--- Add a sokol_main() function to your code which returns a sapp_desc structure + with initialization parameters and callback function pointers. This + function is called very early, usually at the start of the + platform's entry function (e.g. main or WinMain). You should do as + little as possible here, since the rest of your code might be called + from another thread (this depends on the platform): + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc) { + .width = 640, + .height = 480, + .init_cb = my_init_func, + .frame_cb = my_frame_func, + .cleanup_cb = my_cleanup_func, + .event_cb = my_event_func, + ... + }; + } + + To get any logging output in case of errors you need to provide a log + callback. The easiest way is via sokol_log.h: + + #include "sokol_log.h" + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc) { + ... + .logger.func = slog_func, + }; + } + + There are many more setup parameters, but these are the most important. + For a complete list search for the sapp_desc structure declaration + below. + + DO NOT call any sokol-app function from inside sokol_main(), since + sokol-app will not be initialized at this point. + + The .width and .height parameters are the preferred size of the 3D + rendering canvas. The actual size may differ from this depending on + platform and other circumstances. Also the canvas size may change at + any time (for instance when the user resizes the application window, + or rotates the mobile device). You can just keep .width and .height + zero-initialized to open a default-sized window (what "default-size" + exactly means is platform-specific, but usually it's a size that covers + most of, but not all, of the display). + + All provided function callbacks will be called from the same thread, + but this may be different from the thread where sokol_main() was called. + + .init_cb (void (*)(void)) + This function is called once after the application window, + 3D rendering context and swap chain have been created. The + function takes no arguments and has no return value. + .frame_cb (void (*)(void)) + This is the per-frame callback, which is usually called 60 + times per second. This is where your application would update + most of its state and perform all rendering. + .cleanup_cb (void (*)(void)) + The cleanup callback is called once right before the application + quits. + .event_cb (void (*)(const sapp_event* event)) + The event callback is mainly for input handling, but is also + used to communicate other types of events to the application. Keep the + event_cb struct member zero-initialized if your application doesn't require + event handling. + + As you can see, those 'standard callbacks' don't have a user_data + argument, so any data that needs to be preserved between callbacks + must live in global variables.

Note that the cleanup-callback isn't + guaranteed to be called on the web and mobile platforms. + + MOUSE CURSOR TYPE AND VISIBILITY + ================================ + You can show and hide the mouse cursor with + + void sapp_show_mouse(bool show) + + And to get the current shown status: + + bool sapp_mouse_shown(void) + + NOTE that hiding the mouse cursor is different and independent from + the MOUSE/POINTER LOCK feature which will also hide the mouse pointer when + active (MOUSE LOCK is described below). + + To change the mouse cursor to one of several predefined types, call + the function: + + void sapp_set_mouse_cursor(sapp_mouse_cursor cursor) + + Setting the default mouse cursor SAPP_MOUSECURSOR_DEFAULT will restore + the standard look. + + To get the currently active mouse cursor type, call: + + sapp_mouse_cursor sapp_get_mouse_cursor(void) + + MOUSE LOCK (AKA POINTER LOCK, AKA MOUSE CAPTURE) + ================================================ + In normal mouse mode, no mouse movement events are reported when the + mouse leaves the windows client area or hits the screen border (whether + it's one or the other depends on the platform), and the mouse move events + (SAPP_EVENTTYPE_MOUSE_MOVE) contain absolute mouse positions in + framebuffer pixels in the sapp_event items mouse_x and mouse_y, and + relative movement in framebuffer pixels in the sapp_event items mouse_dx + and mouse_dy. + + To get continuous mouse movement (also when the mouse leaves the window + client area or hits the screen border), activate mouse-lock mode + by calling: + + sapp_lock_mouse(true) + + When mouse lock is activated, the mouse pointer is hidden, the + reported absolute mouse position (sapp_event.mouse_x/y) appears + frozen, and the relative mouse movement in sapp_event.mouse_dx/dy + no longer has a direct relation to framebuffer pixels but instead + uses "raw mouse input" (what "raw mouse input" exactly means also + differs by platform). + + To deactivate mouse lock and return to normal mouse mode, call + + sapp_lock_mouse(false) + + And finally, to check if mouse lock is currently active, call + + if (sapp_mouse_locked()) { ... } + + Note that mouse-lock state may not change immediately after sapp_lock_mouse(true/false) + is called, instead on some platforms the actual state switch may be delayed + to the end of the current frame or even to a later frame. + + The mouse may also be unlocked automatically without calling sapp_lock_mouse(false), + most notably when the application window becomes inactive. + + On the web platform there are further restrictions to be aware of, caused + by the limitations of the HTML5 Pointer Lock API: + + - sapp_lock_mouse(true) can be called at any time, but it will + only take effect in a 'short-lived input event handler of a specific + type', meaning when one of the following events happens: + - SAPP_EVENTTYPE_MOUSE_DOWN + - SAPP_EVENTTYPE_MOUSE_UP + - SAPP_EVENTTYPE_MOUSE_SCROLL + - SAPP_EVENTTYPE_KEY_UP + - SAPP_EVENTTYPE_KEY_DOWN + - The mouse lock/unlock action on the web platform is asynchronous, + this means that sapp_mouse_locked() won't immediately return + the new status after calling sapp_lock_mouse(), instead the + reported status will only change when the pointer lock has actually + been activated or deactivated in the browser. + - On the web, mouse lock can be deactivated by the user at any time + by pressing the Esc key. When this happens, sokol_app.h behaves + the same as if sapp_lock_mouse(false) is called. + + For things like camera manipulation it's most straightforward to lock + and unlock the mouse right from the sokol_app.h event handler, for + instance the following code enters and leaves mouse lock when the + left mouse button is pressed and released, and then uses the relative + movement information to manipulate a camera (taken from the + cgltf-sapp.c sample in the sokol-samples repository + at https://github.com/floooh/sokol-samples): + + static void input(const sapp_event* ev) { + switch (ev->type) { + case SAPP_EVENTTYPE_MOUSE_DOWN: + if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) { + sapp_lock_mouse(true); + } + break; + + case SAPP_EVENTTYPE_MOUSE_UP: + if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) { + sapp_lock_mouse(false); + } + break; + + case SAPP_EVENTTYPE_MOUSE_MOVE: + if (sapp_mouse_locked()) { + cam_orbit(&state.camera, ev->mouse_dx * 0.25f, ev->mouse_dy * 0.25f); + } + break; + + default: + break; + } + } + + For a 'first person shooter mouse' the following code inside the sokol-app event handler + is recommended somewhere in your frame callback: + + if (!sapp_mouse_locked()) { + sapp_lock_mouse(true); + } + + CLIPBOARD SUPPORT + ================= + Applications can send and receive UTF-8 encoded text data from and to the + system clipboard. By default, clipboard support is disabled and + must be enabled at startup via the following sapp_desc struct + members: + + sapp_desc.enable_clipboard - set to true to enable clipboard support + sapp_desc.clipboard_size - size of the internal clipboard buffer in bytes + + Enabling the clipboard will dynamically allocate a clipboard buffer + for UTF-8 encoded text data of the requested size in bytes, the default + size is 8 KBytes. Strings that don't fit into the clipboard buffer + (including the terminating zero) will be silently clipped, so it's + important that you provide a big enough clipboard size for your + use case. + + To send data to the clipboard, call sapp_set_clipboard_string() with + a pointer to an UTF-8 encoded, null-terminated C-string. + + NOTE that on the HTML5 platform, sapp_set_clipboard_string() must be + called from inside a 'short-lived event handler', and there are a few + other HTML5-specific caveats to workaround. You'll basically have to + tinker until it works in all browsers :/ (maybe the situation will + improve when all browsers agree on and implement the new + HTML5 navigator.clipboard API). + + To get data from the clipboard, check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED + event in your event handler function, and then call sapp_get_clipboard_string() + to obtain the pasted UTF-8 encoded text. + + NOTE that behaviour of sapp_get_clipboard_string() is slightly different + depending on platform: + + - on the HTML5 platform, the internal clipboard buffer will only be updated + right before the SAPP_EVENTTYPE_CLIPBOARD_PASTED event is sent, + and sapp_get_clipboard_string() will simply return the current content + of the clipboard buffer + - on 'native' platforms, the call to sapp_get_clipboard_string() will + update the internal clipboard buffer with the most recent data + from the system clipboard + + Portable code should check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED event, + and then call sapp_get_clipboard_string() right in the event handler. + + The SAPP_EVENTTYPE_CLIPBOARD_PASTED event will be generated by sokol-app + as follows: + + - on macOS: when the Cmd+V key is pressed down + - on HTML5: when the browser sends a 'paste' event to the global 'window' object + - on all other platforms: when the Ctrl+V key is pressed down + + DRAG AND DROP SUPPORT + ===================== + PLEASE NOTE: the drag'n'drop feature works differently on WASM/HTML5 + and on the native desktop platforms (Win32, Linux and macOS) because + of security-related restrictions in the HTML5 drag'n'drop API. The + WASM/HTML5 specifics are described at the end of this documentation + section: + + Like clipboard support, drag'n'drop support must be explicitly enabled + at startup in the sapp_desc struct. + + sapp_desc sokol_main(void) { + return (sapp_desc) { + .enable_dragndrop = true, // default is false + ... + }; + } + + You can also adjust the maximum number of files that are accepted + in a drop operation, and the maximum path length in bytes if needed: + + sapp_desc sokol_main(void) { + return (sapp_desc) { + .enable_dragndrop = true, // default is false + .max_dropped_files = 8, // default is 1 + .max_dropped_file_path_length = 8192, // in bytes, default is 2048 + ... + }; + } + + When drag'n'drop is enabled, the event callback will be invoked with an + event of type SAPP_EVENTTYPE_FILES_DROPPED whenever the user drops files on + the application window. + + After the SAPP_EVENTTYPE_FILES_DROPPED is received, you can query the + number of dropped files, and their absolute paths by calling separate + functions: + + void on_event(const sapp_event* ev) { + if (ev->type == SAPP_EVENTTYPE_FILES_DROPPED) { + + // the mouse position where the drop happened + float x = ev->mouse_x; + float y = ev->mouse_y; + + // get the number of files and their paths like this: + const int num_dropped_files = sapp_get_num_dropped_files(); + for (int i = 0; i < num_dropped_files; i++) { + const char* path = sapp_get_dropped_file_path(i); + ... + } + } + } + + The returned file paths are UTF-8 encoded strings. + + You can call sapp_get_num_dropped_files() and sapp_get_dropped_file_path() + anywhere, also outside the event handler callback, but be aware that the + file path strings will be overwritten with the next drop operation. + + In any case, sapp_get_dropped_file_path() will never return a null pointer, + instead an empty string "" will be returned if the drag'n'drop feature + hasn't been enabled, the last drop-operation failed, or the file path index + is out of range. + + Drag'n'drop caveats: + + - if more files are dropped in a single drop-action + than sapp_desc.max_dropped_files, the additional + files will be silently ignored + - if any of the file paths is longer than + sapp_desc.max_dropped_file_path_length (in number of bytes, after UTF-8 + encoding) the entire drop operation will be silently ignored (this + needs some sort of error feedback in the future) + - no mouse positions are reported while the drag is in + process, this may change in the future + + Drag'n'drop on HTML5/WASM: + + The HTML5 drag'n'drop API doesn't return file paths, but instead + black-box 'file objects' which must be used to load the content + of dropped files. This is the reason why sokol_app.h adds two + HTML5-specific functions to the drag'n'drop API: + + uint32_t sapp_html5_get_dropped_file_size(int index) + Returns the size in bytes of a dropped file. + + void sapp_html5_fetch_dropped_file(const sapp_html5_fetch_request* request) + Asynchronously loads the content of a dropped file into a + provided memory buffer (which must be big enough to hold + the file content) + + To start loading the first dropped file after an SAPP_EVENTTYPE_FILES_DROPPED + event is received: + + sapp_html5_fetch_dropped_file(&(sapp_html5_fetch_request){ + .dropped_file_index = 0, + .callback = fetch_cb + .buffer = { + .ptr = buf, + .size = sizeof(buf) + }, + .user_data = ... + }); + + Make sure that the memory pointed to by 'buf' stays valid until the + callback function is called! + + As result of the asynchronous loading operation (no matter if succeeded or + failed) the 'fetch_cb' function will be called: + + void fetch_cb(const sapp_html5_fetch_response* response) { + // IMPORTANT: check if the loading operation actually succeeded: + if (response->succeeded) { + // the size of the loaded file: + const size_t num_bytes = response->data.size; + // and the pointer to the data (same as 'buf' in the fetch-call): + const void* ptr = response->data.ptr; + } + else { + // on error check the error code: + switch (response->error_code) { + case SAPP_HTML5_FETCH_ERROR_BUFFER_TOO_SMALL: + ... + break; + case SAPP_HTML5_FETCH_ERROR_OTHER: + ... + break; + } + } + } + + Check the droptest-sapp example for a real-world example which works + both on native platforms and the web: + + https://github.com/floooh/sokol-samples/blob/master/sapp/droptest-sapp.c + + HIGH-DPI RENDERING + ================== + You can set the sapp_desc.high_dpi flag during initialization to request + a full-resolution framebuffer on HighDPI displays. The default behaviour + is sapp_desc.high_dpi=false, this means that the application will + render to a lower-resolution framebuffer on HighDPI displays and the + rendered content will be upscaled by the window system composer. + + In a HighDPI scenario, you still request the same window size during + sokol_main(), but the framebuffer sizes returned by sapp_width() + and sapp_height() will be scaled up according to the DPI scaling + ratio. + + Note that on some platforms the DPI scaling factor may change at any + time (for instance when a window is moved from a high-dpi display + to a low-dpi display). + + To query the current DPI scaling factor, call the function: + + float sapp_dpi_scale(void); + + For instance on a Retina Mac, returning the following sapp_desc + struct from sokol_main(): + + sapp_desc sokol_main(void) { + return (sapp_desc) { + .width = 640, + .height = 480, + .high_dpi = true, + ... + }; + } + + ...the functions the functions sapp_width(), sapp_height() + and sapp_dpi_scale() will return the following values: + + sapp_width: 1280 + sapp_height: 960 + sapp_dpi_scale: 2.0 + + If the high_dpi flag is false, or you're not running on a Retina display, + the values would be: + + sapp_width: 640 + sapp_height: 480 + sapp_dpi_scale: 1.0 + + If the window is moved from the Retina display to a low-dpi external display, + the values would change as follows: + + sapp_width: 1280 => 640 + sapp_height: 960 => 480 + sapp_dpi_scale: 2.0 => 1.0 + + Currently there is no event associated with a DPI change, but an + SAPP_EVENTTYPE_RESIZED will be sent as a side effect of the + framebuffer size changing. + + Per-monitor DPI is currently supported on macOS and Windows. + + APPLICATION QUIT + ================ + Without special quit handling, a sokol_app.h application will quit + 'gracefully' when the user clicks the window close-button unless a + platform's application model prevents this (e.g. on web or mobile). + 'Graceful exit' means that the application-provided cleanup callback will + be called before the application quits. + + On native desktop platforms sokol_app.h provides more control over the + application-quit-process. It's possible to initiate a 'programmatic quit' + from the application code, and a quit initiated by the application user can + be intercepted (for instance to show a custom dialog box). + + This 'programmatic quit protocol' is implemented through 3 functions + and 1 event: + + - sapp_quit(): This function simply quits the application without + giving the user a chance to intervene. Usually this might + be called when the user clicks the 'Ok' button in a 'Really Quit?' + dialog box + - sapp_request_quit(): Calling sapp_request_quit() will send the + event SAPP_EVENTTYPE_QUIT_REQUESTED to the applications event handler + callback, giving the user code a chance to intervene and cancel the + pending quit process (for instance to show a 'Really Quit?' dialog + box). If the event handler callback does nothing, the application + will be quit as usual. To prevent this, call the function + sapp_cancel_quit() from inside the event handler. + - sapp_cancel_quit(): Cancels a pending quit request, either initiated + by the user clicking the window close button, or programmatically + by calling sapp_request_quit(). The only place where calling this + function makes sense is from inside the event handler callback when + the SAPP_EVENTTYPE_QUIT_REQUESTED event has been received. + - SAPP_EVENTTYPE_QUIT_REQUESTED: this event is sent when the user + clicks the window's close button or application code calls the + sapp_request_quit() function. The event handler callback code can handle + this event by calling sapp_cancel_quit() to cancel the quit. + If the event is ignored, the application will quit as usual. + + On the web platform, the quit behaviour differs from native platforms, + because of web-specific restrictions: + + A `programmatic quit` initiated by calling sapp_quit() or + sapp_request_quit() will work as described above: the cleanup callback is + called, platform-specific cleanup is performed (on the web + this means that JS event handlers are unregistered), and then + the request-animation-loop will be exited. However that's all. The + web page itself will continue to exist (e.g. it's not possible to + programmatically close the browser tab). + + On the web it's also not possible to run custom code when the user + closes a browser tab, so it's not possible to prevent this with a + fancy custom dialog box. + + Instead the standard "Leave Site?" dialog box can be activated (or + deactivated) with the following function: + + sapp_html5_ask_leave_site(bool ask); + + The initial state of the associated internal flag can be provided + at startup via sapp_desc.html5_ask_leave_site. + + This feature should only be used sparingly in critical situations - for + instance when the user would loose data - since popping up modal dialog + boxes is considered quite rude in the web world. Note that there's no way + to customize the content of this dialog box or run any code as a result + of the user's decision. Also note that the user must have interacted with + the site before the dialog box will appear. These are all security measures + to prevent fishing. + + The Dear ImGui HighDPI sample contains example code of how to + implement a 'Really Quit?' dialog box with Dear ImGui (native desktop + platforms only), and for showing the hardwired "Leave Site?" dialog box + when running on the web platform: + + https://floooh.github.io/sokol-html5/wasm/imgui-highdpi-sapp.html + + FULLSCREEN + ========== + If the sapp_desc.fullscreen flag is true, sokol-app will try to create + a fullscreen window on platforms with a 'proper' window system + (mobile devices will always use fullscreen). The implementation details + depend on the target platform, in general sokol-app will use a + 'soft approach' which doesn't interfere too much with the platform's + window system (for instance borderless fullscreen window instead of + a 'real' fullscreen mode). Such details might change over time + as sokol-app is adapted for different needs. + + The most important effect of fullscreen mode to keep in mind is that + the requested canvas width and height will be ignored for the initial + window size, calling sapp_width() and sapp_height() will instead return + the resolution of the fullscreen canvas (however the provided size + might still be used for the non-fullscreen window, in case the user can + switch back from fullscreen- to windowed-mode). + + To toggle fullscreen mode programmatically, call sapp_toggle_fullscreen(). + + To check if the application window is currently in fullscreen mode, + call sapp_is_fullscreen(). + + WINDOW ICON SUPPORT + =================== + Some sokol_app.h backends allow to change the window icon programmatically: + + - on Win32: the small icon in the window's title bar, and the + bigger icon in the task bar + - on Linux: highly dependent on the used window manager, but usually + the window's title bar icon and/or the task bar icon + - on HTML5: the favicon shown in the page's browser tab + - on macOS: the application icon shown in the dock, but only + for currently running applications + + NOTE that it is not possible to set the actual application icon which is + displayed by the operating system on the desktop or 'home screen'. Those + icons must be provided 'traditionally' through operating-system-specific + resources which are associated with the application (sokol_app.h might + later support setting the window icon from platform specific resource data + though). + + There are two ways to set the window icon: + + - at application start in the sokol_main() function by initializing + the sapp_desc.icon nested struct + - or later by calling the function sapp_set_icon() + + As a convenient shortcut, sokol_app.h comes with a builtin default-icon + (a rainbow-colored 'S', which at least looks a bit better than the Windows + default icon for applications), which can be activated like this: + + At startup in sokol_main(): + + sapp_desc sokol_main(...) { + return (sapp_desc){ + ... + icon.sokol_default = true + }; + } + + Or later by calling: + + sapp_set_icon(&(sapp_icon_desc){ .sokol_default = true }); + + NOTE that a completely zero-initialized sapp_icon_desc struct will not + update the window icon in any way. This is an 'escape hatch' so that you + can handle the window icon update yourself (or if you do this already, + sokol_app.h won't get in your way, in this case just leave the + sapp_desc.icon struct zero-initialized). + + Providing your own icon images works exactly like in GLFW (down to the + data format): + + You provide one or more 'candidate images' in different sizes, and the + sokol_app.h platform backends pick the best match for the specific backend + and icon type. + + For each candidate image, you need to provide: + + - the width in pixels + - the height in pixels + - and the actual pixel data in RGBA8 pixel format (e.g. 0xFFCC8844 + on a little-endian CPU means: alpha=0xFF, blue=0xCC, green=0x88, red=0x44) + + For instance, if you have 3 candidate images (small, medium, big) of + sizes 16x16, 32x32 and 64x64 the corresponding sapp_icon_desc struct is setup + like this: + + // the actual pixel data (RGBA8, origin top-left) + const uint32_t small[16][16] = { ... }; + const uint32_t medium[32][32] = { ... }; + const uint32_t big[64][64] = { ... }; + + const sapp_icon_desc icon_desc = { + .images = { + { .width = 16, .height = 16, .pixels = SAPP_RANGE(small) }, + { .width = 32, .height = 32, .pixels = SAPP_RANGE(medium) }, + // ...or without the SAPP_RANGE helper macro: + { .width = 64, .height = 64, .pixels = { .ptr=big, .size=sizeof(big) } } + } + }; + + An sapp_icon_desc struct initialized like this can then either be applied + at application start in sokol_main: + + sapp_desc sokol_main(...) { + return (sapp_desc){ + ... + icon = icon_desc + }; + } + + ...or later by calling sapp_set_icon(): + + sapp_set_icon(&icon_desc); + + Some window icon caveats: + + - once the window icon has been updated, there's no way to go back to + the platform's default icon, this is because some platforms (Linux + and HTML5) don't switch the icon visual back to the default even if + the custom icon is deleted or removed + - on HTML5, if the sokol_app.h icon doesn't show up in the browser + tab, check that there's no traditional favicon 'link' element + is defined in the page's index.html, sokol_app.h will only + append a new favicon link element, but not delete any manually + defined favicon in the page + + For an example and test of the window icon feature, check out the + 'icon-sapp' sample on the sokol-samples git repository. + + ONSCREEN KEYBOARD + ================= + On some platforms which don't provide a physical keyboard, sokol-app + can display the platform's integrated onscreen keyboard for text + input. To request that the onscreen keyboard is shown, call + + sapp_show_keyboard(true); + + Likewise, to hide the keyboard call: + + sapp_show_keyboard(false); + + Note that onscreen keyboard functionality is no longer supported + on the browser platform (the previous hacks and workarounds to make browser + keyboards work for on web applications that don't use HTML UIs + never really worked across browsers). + + INPUT EVENT BUBBLING ON THE WEB PLATFORM + ======================================== + By default, input event bubbling on the web platform is configured in + a way that makes the most sense for 'full-canvas' apps that cover the + entire browser client window area: + + - mouse, touch and wheel events do not bubble up, this prevents various + ugly side events, like: + - HTML text overlays being selected on double- or triple-click into + the canvas + - 'scroll bumping' even when the canvas covers the entire client area + - key_up/down events for 'character keys' *do* bubble up (otherwise + the browser will not generate UNICODE character events) + - all other key events *do not* bubble up by default (this prevents side effects + like F1 opening help, or F7 starting 'caret browsing') + - character events do not bubble up (although I haven't noticed any side effects + otherwise) + + Event bubbling can be enabled for input event categories during initialization + in the sapp_desc struct: + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc){ + //... + .html5_bubble_mouse_events = true, + .html5_bubble_touch_events = true, + .html5_bubble_wheel_events = true, + .html5_bubble_key_events = true, + .html5_bubble_char_events = true, + }; + } + + This basically opens the floodgates and lets *all* input events bubble up to the browser. + + To prevent individual events from bubbling, call sapp_consume_event() from within + the sokol_app.h event callback when that specific event is reported. + + + SETTING THE CANVAS OBJECT ON THE WEB PLATFORM + ============================================= + On the web, sokol_app.h and the Emscripten SDK functions need to find + the WebGL/WebGPU canvas intended for rendering and attaching event + handlers. This can happen in four ways: + + 1. do nothing and just set the id of the canvas object to 'canvas' (preferred) + 2. via a CSS Selector string (preferred) + 3. by setting the `Module.canvas` property to the canvas object + 4. by adding the canvas object to the global variable `specialHTMLTargets[]` + (this is a special variable used by the Emscripten runtime to lookup + event target objects for which document.querySelector() cannot be used) + + The easiest way is to just name your canvas object 'canvas': + +

+ + This works because the default css selector string used by sokol_app.h + is '#canvas'. + + If you name your canvas differently, you need to communicate that name to + sokol_app.h via `sapp_desc.html5_canvas_selector` as a regular css selector + string that's compatible with `document.querySelector()`. E.g. if your canvas + object looks like this: + +

+ + The `sapp_desc.html5_canvas_selector` string must be set to '#bla': + + .html5_canvas_selector = "#bla" + + If the canvas object cannot be looked up via `document.querySelector()` you + need to use one of the alternative methods, both involve the special + Emscripten runtime `Module` object which is usually setup in the index.html + like this before the WASM blob is loaded and instantiated: + + + + The first option is to set the `Module.canvas` property to your canvas object: + + + + When sokol_app.h initializes, it will check the global Module object whether + a `Module.canvas` property exists and is an object. This method will add + a new entry to the `specialHTMLTargets[]` object + + The other option is to add the canvas under a name chosen by you to the + special `specialHTMLTargets[]` map, which is used by the Emscripten runtime + to lookup 'event target objects' which are not visible to `document.querySelector()`. + Note that `specialHTMLTargets[]` must be updated after the Emscripten runtime + has started but before the WASM code is running. A good place for this is + the special `Module.preRun` array in index.html: + + + + In that case, pass the same string to sokol_app.h which is used as key + in the specialHTMLTargets[] map: + + .html5_canvas_selector = "my_canvas" + + If sokol_app.h can't find your canvas for some reason check for warning + messages on the browser console. + + + OPTIONAL: DON'T HIJACK main() (#define SOKOL_NO_ENTRY) + ====================================================== + NOTE: SOKOL_NO_ENTRY and sapp_run() is currently not supported on Android. + + In its default configuration, sokol_app.h "hijacks" the platform's + standard main() function. This was done because different platforms + have different entry point conventions which are not compatible with + C's main() (for instance WinMain on Windows has completely different + arguments). However, this "main hijacking" posed a problem for + usage scenarios like integrating sokol_app.h with other languages than + C or C++, so an alternative SOKOL_NO_ENTRY mode has been added + in which the user code provides the platform's main function: + + - define SOKOL_NO_ENTRY before including the sokol_app.h implementation + - do *not* provide a sokol_main() function + - instead provide the standard main() function of the platform + - from the main function, call the function ```sapp_run()``` which + takes a pointer to an ```sapp_desc``` structure. + - from here on```sapp_run()``` takes over control and calls the provided + init-, frame-, event- and cleanup-callbacks just like in the default model. + + sapp_run() behaves differently across platforms: + + - on some platforms, sapp_run() will return when the application quits + - on other platforms, sapp_run() will never return, even when the + application quits (the operating system is free to simply terminate + the application at any time) + - on Emscripten specifically, sapp_run() will return immediately while + the frame callback keeps being called + + This different behaviour of sapp_run() essentially means that there shouldn't + be any code *after* sapp_run(), because that may either never be called, or in + case of Emscripten will be called at an unexpected time (at application start). + + An application also should not depend on the cleanup-callback being called + when cross-platform compatibility is required. + + Since sapp_run() returns immediately on Emscripten you shouldn't activate + the 'EXIT_RUNTIME' linker option (this is disabled by default when compiling + for the browser target), since the C/C++ exit runtime would be called immediately at + application start, causing any global objects to be destroyed and global + variables to be zeroed. + + WINDOWS CONSOLE OUTPUT + ====================== + On Windows, regular windowed applications don't show any stdout/stderr text + output, which can be a bit of a hassle for printf() debugging or generally + logging text to the console. Also, console output by default uses a local + codepage setting and thus international UTF-8 encoded text is printed + as garbage. + + To help with these issues, sokol_app.h can be configured at startup + via the following Windows-specific sapp_desc flags: + + sapp_desc.win32_console_utf8 (default: false) + When set to true, the output console codepage will be switched + to UTF-8 (and restored to the original codepage on exit) + + sapp_desc.win32_console_attach (default: false) + When set to true, stdout and stderr will be attached to the + console of the parent process (if the parent process actually + has a console). This means that if the application was started + in a command line window, stdout and stderr output will be printed + to the terminal, just like a regular command line program. But if + the application is started via double-click, it will behave like + a regular UI application, and stdout/stderr will not be visible. + + sapp_desc.win32_console_create (default: false) + When set to true, a new console window will be created and + stdout/stderr will be redirected to that console window. It + doesn't matter if the application is started from the command + line or via double-click. + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc){ + // ... + .allocator = { + .alloc_fn = my_alloc, + .free_fn = my_free, + .user_data = ..., + } + }; + } + + If no overrides are provided, malloc and free will be used. + + This only affects memory allocation calls done by sokol_app.h + itself though, not any allocations in OS libraries. + + + ERROR REPORTING AND LOGGING + =========================== + To get any logging information at all you need to provide a logging callback in the setup call + the easiest way is to use sokol_log.h: + + #include "sokol_log.h" + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc) { + ... + .logger.func = slog_func, + }; + } + + To override logging with your own callback, first write a logging function like this: + + void my_log(const char* tag, // e.g. 'sapp' + uint32_t log_level, // 0=panic, 1=error, 2=warn, 3=info + uint32_t log_item_id, // SAPP_LOGITEM_* + const char* message_or_null, // a message string, may be nullptr in release mode + uint32_t line_nr, // line number in sokol_app.h + const char* filename_or_null, // source filename, may be nullptr in release mode + void* user_data) + { + ... + } + + ...and then setup sokol-app like this: + + sapp_desc sokol_main(int argc, char* argv[]) { + return (sapp_desc) { + ... + .logger = { + .func = my_log, + .user_data = my_user_data, + } + }; + } + + The provided logging function must be reentrant (e.g. be callable from + different threads). + + If you don't want to provide your own custom logger it is highly recommended to use + the standard logger in sokol_log.h instead, otherwise you won't see any warnings or + errors. + + TEMP NOTE DUMP + ============== + - sapp_desc needs a bool whether to initialize depth-stencil surface + - the Android implementation calls cleanup_cb() and destroys the egl context in onDestroy + at the latest but should do it earlier, in onStop, as an app is "killable" after onStop + on Android Honeycomb and later (it can't be done at the moment as the app may be started + again after onStop and the sokol lifecycle does not yet handle context teardown/bringup) + + + LICENSE + ======= + zlib/libpng license + + Copyright (c) 2018 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

Callback model: You provide a callback function, which will be called + when Sokol Audio needs new samples. On all platforms except emscripten, + this function is called from a separate thread. + 2. Push model: Your code pushes small blocks of sample data from your + main loop or a thread you created. The pushed data is stored in + a ring buffer where it is pulled by the backend code when + needed. + + The callback model is preferred because it is the most direct way to + feed sample data into the audio backends and also has less moving parts + (there is no ring buffer between your code and the audio backend). + + Sometimes it is not possible to generate the audio stream directly in a + callback function running in a separate thread, for such cases Sokol Audio + provides the push-model as a convenience. + + SOKOL AUDIO, SOLOUD AND MINIAUDIO + ================================= + The WASAPI, ALSA and CoreAudio backend code has been taken from the + SoLoud library (with some modifications, so any bugs in there are most + likely my fault). If you need a more fully-featured audio solution, check + out SoLoud, it's excellent: + + https://github.com/jarikomppa/soloud + + Another alternative which feature-wise is somewhere inbetween SoLoud and + sokol-audio might be MiniAudio: + + https://github.com/mackron/miniaudio + + GLOSSARY + ======== + - stream buffer: + The internal audio data buffer, usually provided by the backend API. The + size of the stream buffer defines the base latency, smaller buffers have + lower latency but may cause audio glitches. Bigger buffers reduce or + eliminate glitches, but have a higher base latency. + + - stream callback: + Optional callback function which is called by Sokol Audio when it + needs new samples. On Windows, macOS/iOS and Linux, this is called in + a separate thread, on WebAudio, this is called per-frame in the + browser thread. + + - channel: + A discrete track of audio data, currently 1-channel (mono) and + 2-channel (stereo) is supported and tested. + + - sample: + The magnitude of an audio signal on one channel at a given time. In + Sokol Audio, samples are 32-bit float numbers in the range -1.0 to + +1.0. + + - frame: + The tightly packed set of samples for all channels at a given time. + For mono 1 frame is 1 sample. For stereo, 1 frame is 2 samples. + + - packet: + In Sokol Audio, a small chunk of audio data that is moved from the + main thread to the audio streaming thread in order to decouple the + rate at which the main thread provides new audio data, and the + streaming thread consuming audio data. + + WORKING WITH SOKOL AUDIO + ======================== + First call saudio_setup() with your preferred audio playback options. + In most cases you can stick with the default values, these provide + a good balance between low-latency and glitch-free playback + on all audio backends. + + You should always provide a logging callback to be aware of any + warnings and errors. The easiest way is to use sokol_log.h for this: + + #include "sokol_log.h" + // ... + saudio_setup(&(saudio_desc){ + .logger = { + .func = slog_func, + } + }); + + If you want to use the callback-model, you need to provide a stream + callback function either in saudio_desc.stream_cb or saudio_desc.stream_userdata_cb, + otherwise keep both function pointers zero-initialized. + + Use push model and default playback parameters: + + saudio_setup(&(saudio_desc){ .logger.func = slog_func }); + + Use stream callback model and default playback parameters: + + saudio_setup(&(saudio_desc){ + .stream_cb = my_stream_callback + .logger.func = slog_func, + }); + + The standard stream callback doesn't have a user data argument, if you want + that, use the alternative stream_userdata_cb and also set the user_data pointer: + + saudio_setup(&(saudio_desc){ + .stream_userdata_cb = my_stream_callback, + .user_data = &my_data + .logger.func = slog_func, + }); + + The following playback parameters can be provided through the + saudio_desc struct: + + General parameters (both for stream-callback and push-model): + + int sample_rate -- the sample rate in Hz, default: 44100 + int num_channels -- number of channels, default: 1 (mono) + int buffer_frames -- number of frames in streaming buffer, default: 2048 + + The stream callback prototype (either with or without userdata): + + void (*stream_cb)(float* buffer, int num_frames, int num_channels) + void (*stream_userdata_cb)(float* buffer, int num_frames, int num_channels, void* user_data) + Function pointer to the user-provide stream callback. + + Push-model parameters: + + int packet_frames -- number of frames in a packet, default: 128 + int num_packets -- number of packets in ring buffer, default: 64 + + The sample_rate and num_channels parameters are only hints for the audio + backend, it isn't guaranteed that those are the values used for actual + playback. + + To get the actual parameters, call the following functions after + saudio_setup(): + + int saudio_sample_rate(void) + int saudio_channels(void); + + It's unlikely that the number of channels will be different than requested, + but a different sample rate isn't uncommon. + + (NOTE: there's an yet unsolved issue when an audio backend might switch + to a different sample rate when switching output devices, for instance + plugging in a bluetooth headset, this case is currently not handled in + Sokol Audio). + + You can check if audio initialization was successful with + saudio_isvalid(). If backend initialization failed for some reason + (for instance when there's no audio device in the machine), this + will return false. Not checking for success won't do any harm, all + Sokol Audio function will silently fail when called after initialization + has failed, so apart from missing audio output, nothing bad will happen. + + Before your application exits, you should call + + saudio_shutdown(); + + This stops the audio thread (on Linux, Windows and macOS/iOS) and + properly shuts down the audio backend. + + THE STREAM CALLBACK MODEL + ========================= + To use Sokol Audio in stream-callback-mode, provide a callback function + like this in the saudio_desc struct when calling saudio_setup(): + + void stream_cb(float* buffer, int num_frames, int num_channels) { + ... + } + + Or the alternative version with a user-data argument: + + void stream_userdata_cb(float* buffer, int num_frames, int num_channels, void* user_data) { + my_data_t* my_data = (my_data_t*) user_data; + ... + } + + The job of the callback function is to fill the *buffer* with 32-bit + float sample values. + + To output silence, fill the buffer with zeros: + + void stream_cb(float* buffer, int num_frames, int num_channels) { + const int num_samples = num_frames * num_channels; + for (int i = 0; i < num_samples; i++) { + buffer[i] = 0.0f; + } + } + + For stereo output (num_channels == 2), the samples for the left + and right channel are interleaved: + + void stream_cb(float* buffer, int num_frames, int num_channels) { + assert(2 == num_channels); + for (int i = 0; i < num_frames; i++) { + buffer[2*i + 0] = ...; // left channel + buffer[2*i + 1] = ...; // right channel + } + } + + Please keep in mind that the stream callback function is running in a + separate thread, if you need to share data with the main thread you need + to take care yourself to make the access to the shared data thread-safe! + + THE PUSH MODEL + ============== + To use the push-model for providing audio data, simply don't set (keep + zero-initialized) the stream_cb field in the saudio_desc struct when + calling saudio_setup(). + + To provide sample data with the push model, call the saudio_push() + function at regular intervals (for instance once per frame). You can + call the saudio_expect() function to ask Sokol Audio how much room is + in the ring buffer, but if you provide a continuous stream of data + at the right sample rate, saudio_expect() isn't required (it's a simple + way to sync/throttle your sample generation code with the playback + rate though). + + With saudio_push() you may need to maintain your own intermediate sample + buffer, since pushing individual sample values isn't very efficient. + The following example is from the MOD player sample in + sokol-samples (https://github.com/floooh/sokol-samples): + + const int num_frames = saudio_expect(); + if (num_frames > 0) { + const int num_samples = num_frames * saudio_channels(); + read_samples(flt_buf, num_samples); + saudio_push(flt_buf, num_frames); + } + + Another option is to ignore saudio_expect(), and just push samples as they + are generated in small batches. In this case you *need* to generate the + samples at the right sample rate: + + The following example is taken from the Tiny Emulators project + (https://github.com/floooh/chips-test), this is for mono playback, + so (num_samples == num_frames): + + // tick the sound generator + if (ay38910_tick(&sys->psg)) { + // new sample is ready + sys->sample_buffer[sys->sample_pos++] = sys->psg.sample; + if (sys->sample_pos == sys->num_samples) { + // new sample packet is ready + saudio_push(sys->sample_buffer, sys->num_samples); + sys->sample_pos = 0; + } + } + + THE WEBAUDIO BACKEND + ==================== + The WebAudio backend is currently using a ScriptProcessorNode callback to + feed the sample data into WebAudio. ScriptProcessorNode has been + deprecated for a while because it is running from the main thread, with + the default initialization parameters it works 'pretty well' though. + Ultimately Sokol Audio will use Audio Worklets, but this requires a few + more things to fall into place (Audio Worklets implemented everywhere, + SharedArrayBuffers enabled again, and I need to figure out a 'low-cost' + solution in terms of implementation effort, since Audio Worklets are + a lot more complex than ScriptProcessorNode if the audio data needs to come + from the main thread). + + The WebAudio backend is automatically selected when compiling for + emscripten (__EMSCRIPTEN__ define exists). + + https://developers.google.com/web/updates/2017/12/audio-worklet + https://developers.google.com/web/updates/2018/06/audio-worklet-design-pattern + + "Blob URLs": https://www.html5rocks.com/en/tutorials/workers/basics/ + + Also see: https://blog.paul.cx/post/a-wait-free-spsc-ringbuffer-for-the-web/ + + THE COREAUDIO BACKEND + ===================== + The CoreAudio backend is selected on macOS and iOS (__APPLE__ is defined). + Since the CoreAudio API is implemented in C (not Objective-C) on macOS the + implementation part of Sokol Audio can be included into a C source file. + + However on iOS, Sokol Audio must be compiled as Objective-C due to it's + reliance on the AVAudioSession object. The iOS code path support both + being compiled with or without ARC (Automatic Reference Counting). + + For thread synchronisation, the CoreAudio backend will use the + pthread_mutex_* functions. + + The incoming floating point samples will be directly forwarded to + CoreAudio without further conversion. + + macOS and iOS applications that use Sokol Audio need to link with + the AudioToolbox framework. + + THE WASAPI BACKEND + ================== + The WASAPI backend is automatically selected when compiling on Windows + (_WIN32 is defined). + + For thread synchronisation a Win32 critical section is used. + + WASAPI may use a different size for its own streaming buffer then requested, + so the base latency may be slightly bigger. The current backend implementation + converts the incoming floating point sample values to signed 16-bit + integers. + + The required Windows system DLLs are linked with #pragma comment(lib, ...), + so you shouldn't need to add additional linker libs in the build process + (otherwise this is a bug which should be fixed in sokol_audio.h). + + THE ALSA BACKEND + ================ + The ALSA backend is automatically selected when compiling on Linux + ('linux' is defined). + + For thread synchronisation, the pthread_mutex_* functions are used. + + Samples are directly forwarded to ALSA in 32-bit float format, no + further conversion is taking place. + + You need to link with the 'asound' library, and the + header must be present (usually both are installed with some sort + of ALSA development package). + + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + ... + saudio_setup(&(saudio_desc){ + // ... + .allocator = { + .alloc_fn = my_alloc, + .free_fn = my_free, + .user_data = ..., + } + }); + ... + + If no overrides are provided, malloc and free will be used. + + This only affects memory allocation calls done by sokol_audio.h + itself though, not any allocations in OS libraries. + + Memory allocation will only happen on the same thread where saudio_setup() + was called, so you don't need to worry about thread-safety. + + + ERROR REPORTING AND LOGGING + =========================== + To get any logging information at all you need to provide a logging callback in the setup call + the easiest way is to use sokol_log.h: + + #include "sokol_log.h" + + saudio_setup(&(saudio_desc){ .logger.func = slog_func }); + + To override logging with your own callback, first write a logging function like this: + + void my_log(const char* tag, // e.g. 'saudio' + uint32_t log_level, // 0=panic, 1=error, 2=warn, 3=info + uint32_t log_item_id, // SAUDIO_LOGITEM_* + const char* message_or_null, // a message string, may be nullptr in release mode + uint32_t line_nr, // line number in sokol_audio.h + const char* filename_or_null, // source filename, may be nullptr in release mode + void* user_data) + { + ... + } + + ...and then setup sokol-audio like this: + + saudio_setup(&(saudio_desc){ + .logger = { + .func = my_log, + .user_data = my_user_data, + } + }); + + The provided logging function must be reentrant (e.g. be callable from + different threads). + + If you don't want to provide your own custom logger it is highly recommended to use + the standard logger in sokol_log.h instead, otherwise you won't see any warnings or + errors. + + + LICENSE + ======= + + zlib/libpng license + + Copyright (c) 2018 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

X X . byte 6: 0x66 + . . . . . . . . byte 7: 0x00 + + A complete font consists of 256 characters, resulting in 2048 bytes for + the font data array (but note that the character codes 0..31 will never + be rendered). + + If you provide such a complete font data array, you can drop the .first_char + and .last_char initialization parameters since those default to 0 and 255, + note that you can also use the SDTX_RANGE() helper macro to build the + .data item: + + sdtx_setup(&sdtx_desc_t){ + .fonts = { + [0] = sdtx_font_kc853(), + [1] = { + .data = SDTX_RANGE(my_font_data) + } + } + }); + + If the font doesn't define all 256 character tiles, or you don't need an + entire 256-character font and want to save a couple of bytes, use the + .first_char and .last_char initialization parameters to define a sub-range. + For instance if the font only contains the characters between the Space + (ASCII code 32) and uppercase character 'Z' (ASCII code 90): + + sdtx_setup(&sdtx_desc_t){ + .fonts = { + [0] = sdtx_font_kc853(), + [1] = { + .data = SDTX_RANGE(my_font_data), + .first_char = 32, // could also write ' ' + .last_char = 90 // could also write 'Z' + } + } + }); + + Character tiles that haven't been defined in the font will be rendered + as a solid 8x8 quad. + + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + ... + sdtx_setup(&(sdtx_desc_t){ + // ... + .allocator = { + .alloc_fn = my_alloc, + .free_fn = my_free, + .user_data = ...; + } + }); + ... + + If no overrides are provided, malloc and free will be used. + + + ERROR REPORTING AND LOGGING + =========================== + To get any logging information at all you need to provide a logging callback in the setup call, + the easiest way is to use sokol_log.h: + + #include "sokol_log.h" + + sdtx_setup(&(sdtx_desc_t){ + // ... + .logger.func = slog_func + }); + + To override logging with your own callback, first write a logging function like this: + + void my_log(const char* tag, // e.g. 'sdtx' + uint32_t log_level, // 0=panic, 1=error, 2=warn, 3=info + uint32_t log_item_id, // SDTX_LOGITEM_* + const char* message_or_null, // a message string, may be nullptr in release mode + uint32_t line_nr, // line number in sokol_debugtext.h + const char* filename_or_null, // source filename, may be nullptr in release mode + void* user_data) + { + ... + } + + ...and then setup sokol-debugtext like this: + + sdtx_setup(&(sdtx_desc_t){ + .logger = { + .func = my_log, + .user_data = my_user_data, + } + }); + + The provided logging function must be reentrant (e.g. be callable from + different threads). + + If you don't want to provide your own custom logger it is highly recommended to use + the standard logger in sokol_log.h instead, otherwise you won't see any warnings or + errors. + + + LICENSE + ======= + zlib/libpng license + + Copyright (c) 2020 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

lot about "IO threads". Actual + threads are only used on platforms where threads are available. The web + version (emscripten/wasm) doesn't use POSIX-style threads, but instead + asynchronous Javascript calls chained together by callbacks. The actual + source code differences between the two approaches have been kept to + a minimum though. + + FEATURE OVERVIEW + ================ + + - Asynchronously load complete files, or stream files incrementally via + HTTP (on web platform), or the local file system (on native platforms) + + - Request / response-callback model, user code sends a request + to initiate a file-load, sokol_fetch.h calls the response callback + on the same thread when data is ready or user-code needs + to respond otherwise + + - Not limited to the main-thread or a single thread: A sokol-fetch + "context" can live on any thread, and multiple contexts + can operate side-by-side on different threads. + + - Memory management for data buffers is under full control of user code. + sokol_fetch.h won't allocate memory after it has been setup. + + - Automatic rate-limiting guarantees that only a maximum number of + requests is processed at any one time, allowing a zero-allocation + model, where all data is streamed into fixed-size, pre-allocated + buffers. + + - Active Requests can be paused, continued and cancelled from anywhere + in the user-thread which sent this request. + + + TL;DR EXAMPLE CODE + ================== + This is the most-simple example code to load a single data file with a + known maximum size: + + (1) initialize sokol-fetch with default parameters (but NOTE that the + default setup parameters provide a safe-but-slow "serialized" + operation). In order to see any logging output in case or errors + you should always provide a logging function + (such as 'slog_func' from sokol_log.h): + + sfetch_setup(&(sfetch_desc_t){ .logger.func = slog_func }); + + (2) send a fetch-request to load a file from the current directory + into a buffer big enough to hold the entire file content: + + static uint8_t buf[MAX_FILE_SIZE]; + + sfetch_send(&(sfetch_request_t){ + .path = "my_file.txt", + .callback = response_callback, + .buffer = { + .ptr = buf, + .size = sizeof(buf) + } + }); + + If 'buf' is a value (e.g. an array or struct item), the .buffer item can + be initialized with the SFETCH_RANGE() helper macro: + + sfetch_send(&(sfetch_request_t){ + .path = "my_file.txt", + .callback = response_callback, + .buffer = SFETCH_RANGE(buf) + }); + + (3) write a 'response-callback' function, this will be called whenever + the user-code must respond to state changes of the request + (most importantly when data has been loaded): + + void response_callback(const sfetch_response_t* response) { + if (response->fetched) { + // data has been loaded, and is available via the + // sfetch_range_t struct item 'data': + const void* ptr = response->data.ptr; + size_t num_bytes = response->data.size; + } + if (response->finished) { + // the 'finished'-flag is the catch-all flag for when the request + // is finished, no matter if loading was successful or failed, + // so any cleanup-work should happen here... + ... + if (response->failed) { + // 'failed' is true in (addition to 'finished') if something + // went wrong (file doesn't exist, or less bytes could be + // read from the file than expected) + } + } + } + + (4) pump the sokol-fetch message queues, and invoke response callbacks + by calling: + + sfetch_dowork(); + + In an event-driven app this should be called in the event loop. If you + use sokol-app this would be in your frame_cb function. + + (5) finally, call sfetch_shutdown() at the end of the application: + + There's many other loading-scenarios, for instance one doesn't have to + provide a buffer upfront, this can also happen in the response callback. + + Or it's possible to stream huge files into small fixed-size buffer, + complete with pausing and continuing the download. + + It's also possible to improve the 'pipeline throughput' by fetching + multiple files in parallel, but at the same time limit the maximum + number of requests that can be 'in-flight'. + + For how this all works, please read the following documentation sections :) + + + API DOCUMENTATION + ================= + + void sfetch_setup(const sfetch_desc_t* desc) + -------------------------------------------- + First call sfetch_setup(const sfetch_desc_t*) on any thread before calling + any other sokol-fetch functions on the same thread. + + sfetch_setup() takes a pointer to an sfetch_desc_t struct with setup + parameters. Parameters which should use their default values must + be zero-initialized: + + - max_requests (uint32_t): + The maximum number of requests that can be alive at any time, the + default is 128. + + - num_channels (uint32_t): + The number of "IO channels" used to parallelize and prioritize + requests, the default is 1. + + - num_lanes (uint32_t): + The number of "lanes" on a single channel. Each request which is + currently 'inflight' on a channel occupies one lane until the + request is finished. This is used for automatic rate-limiting + (search below for CHANNELS AND LANES for more details). The + default number of lanes is 1. + + For example, to setup sokol-fetch for max 1024 active requests, 4 channels, + and 8 lanes per channel in C99: + + sfetch_setup(&(sfetch_desc_t){ + .max_requests = 1024, + .num_channels = 4, + .num_lanes = 8 + }); + + sfetch_setup() is the only place where sokol-fetch will allocate memory. + + NOTE that the default setup parameters of 1 channel and 1 lane per channel + has a very poor 'pipeline throughput' since this essentially serializes + IO requests (a new request will only be processed when the last one has + finished), and since each request needs at least one roundtrip between + the user- and IO-thread the throughput will be at most one request per + frame. Search for LATENCY AND THROUGHPUT below for more information on + how to increase throughput. + + NOTE that you can call sfetch_setup() on multiple threads, each thread + will get its own thread-local sokol-fetch instance, which will work + independently from sokol-fetch instances on other threads. + + void sfetch_shutdown(void) + -------------------------- + Call sfetch_shutdown() at the end of the application to stop any + IO threads and free all memory that was allocated in sfetch_setup(). + + sfetch_handle_t sfetch_send(const sfetch_request_t* request) + ------------------------------------------------------------ + Call sfetch_send() to start loading data, the function takes a pointer to an + sfetch_request_t struct with request parameters and returns a + sfetch_handle_t identifying the request for later calls. At least + a path/URL and callback must be provided: + + sfetch_handle_t h = sfetch_send(&(sfetch_request_t){ + .path = "my_file.txt", + .callback = my_response_callback + }); + + sfetch_send() will return an invalid handle if no request can be allocated + from the internal pool because all available request items are 'in-flight'. + + The sfetch_request_t struct contains the following parameters (optional + parameters that are not provided must be zero-initialized): + + - path (const char*, required) + Pointer to an UTF-8 encoded C string describing the filesystem + path or HTTP URL. The string will be copied into an internal data + structure, and passed "as is" (apart from any required + encoding-conversions) to fopen(), CreateFileW() or + the html fetch API call. The maximum length of the string is defined by + the SFETCH_MAX_PATH configuration define, the default is 1024 bytes + including the 0-terminator byte. + + - callback (sfetch_callback_t, required) + Pointer to a response-callback function which is called when the + request needs "user code attention". Search below for REQUEST + STATES AND THE RESPONSE CALLBACK for detailed information about + handling responses in the response callback. + + - channel (uint32_t, optional) + Index of the IO channel where the request should be processed. + Channels are used to parallelize and prioritize requests relative + to each other. Search below for CHANNELS AND LANES for more + information. The default channel is 0. + + - chunk_size (uint32_t, optional) + The chunk_size member is used for streaming data incrementally + in small chunks. After 'chunk_size' bytes have been loaded into + to the streaming buffer, the response callback will be called + with the buffer containing the fetched data for the current chunk. + If chunk_size is 0 (the default), than the whole file will be loaded. + Please search below for CHUNK SIZE AND HTTP COMPRESSION for + important information how streaming works if the web server + is serving compressed data. + + - buffer (sfetch_range_t) + This is a optional pointer/size pair describing a chunk of memory where + data will be loaded into (if no buffer is provided upfront, this + must happen in the response callback). If a buffer is provided, + it must be big enough to either hold the entire file (if chunk_size + is zero), or the *uncompressed* data for one downloaded chunk + (if chunk_size is > 0). + + - user_data (sfetch_range_t) + The user_data ptr/size range struct describe an optional POD blob + (plain-old-data) associated with the request which will be copied(!) + into an internal memory block. The maximum default size of this + memory block is 128 bytes (but can be overridden by defining + SFETCH_MAX_USERDATA_UINT64 before including the notification, note + that this define is in "number of uint64_t", not number of bytes). + The user-data block is 8-byte aligned, and will be copied via + memcpy() (so don't put any C++ "smart members" in there). + + NOTE that request handles are strictly thread-local and only unique + within the thread the handle was created on, and all function calls + involving a request handle must happen on that same thread. + + bool sfetch_handle_valid(sfetch_handle_t request) + ------------------------------------------------- + This checks if the provided request handle is valid, and is associated with + a currently active request. It will return false if: + + - sfetch_send() returned an invalid handle because it couldn't allocate + a new request from the internal request pool (because they're all + in flight) + - the request associated with the handle is no longer alive (because + it either finished successfully, or the request failed for some + reason) + + void sfetch_dowork(void) + ------------------------ + Call sfetch_dowork(void) in regular intervals (for instance once per frame) + on the same thread as sfetch_setup() to "turn the gears". If you are sending + requests but never hear back from them in the response callback function, then + the most likely reason is that you forgot to add the call to sfetch_dowork() + in the per-frame function. + + sfetch_dowork() roughly performs the following work: + + - any new requests that have been sent with sfetch_send() since the + last call to sfetch_dowork() will be dispatched to their IO channels + and assigned a free lane. If all lanes on that channel are occupied + by requests 'in flight', incoming requests must wait until + a lane becomes available + + - for all new requests which have been enqueued on a channel which + don't already have a buffer assigned the response callback will be + called with (response->dispatched == true) so that the response + callback can inspect the dynamically assigned lane and bind a buffer + to the request (search below for CHANNELS AND LANE for more info) + + - a state transition from "user side" to "IO thread side" happens for + each new request that has been dispatched to a channel. + + - requests dispatched to a channel are either forwarded into that + channel's worker thread (on native platforms), or cause an HTTP + request to be sent via an asynchronous fetch() call (on the web + platform) + + - for all requests which have finished their current IO operation a + state transition from "IO thread side" to "user side" happens, + and the response callback is called so that the fetched data + can be processed. + + - requests which are completely finished (either because the entire + file content has been loaded, or they are in the FAILED state) are + freed (this just changes their state in the 'request pool', no actual + memory is freed) + + - requests which are not yet finished are fed back into the + 'incoming' queue of their channel, and the cycle starts again, this + only happens for requests which perform data streaming (not load + the entire file at once). + + void sfetch_cancel(sfetch_handle_t request) + ------------------------------------------- + This cancels a request in the next sfetch_dowork() call and invokes the + response callback with (response.failed == true) and (response.finished + == true) to give user-code a chance to do any cleanup work for the + request. If sfetch_cancel() is called for a request that is no longer + alive, nothing bad will happen (the call will simply do nothing). + + void sfetch_pause(sfetch_handle_t request) + ------------------------------------------ + This pauses an active request in the next sfetch_dowork() call and puts + it into the PAUSED state. For all requests in PAUSED state, the response + callback will be called in each call to sfetch_dowork() to give user-code + a chance to CONTINUE the request (by calling sfetch_continue()). Pausing + a request makes sense for dynamic rate-limiting in streaming scenarios + (like video/audio streaming with a fixed number of streaming buffers. As + soon as all available buffers are filled with download data, downloading + more data must be prevented to allow video/audio playback to catch up and + free up empty buffers for new download data. + + void sfetch_continue(sfetch_handle_t request) + --------------------------------------------- + Continues a paused request, counterpart to the sfetch_pause() function. + + void sfetch_bind_buffer(sfetch_handle_t request, sfetch_range_t buffer) + ---------------------------------------------------------------------------------------- + This "binds" a new buffer (as pointer/size pair) to an active request. The + function *must* be called from inside the response-callback, and there + must not already be another buffer bound. + + void* sfetch_unbind_buffer(sfetch_handle_t request) + --------------------------------------------------- + This removes the current buffer binding from the request and returns + a pointer to the previous buffer (useful if the buffer was dynamically + allocated and it must be freed). + + sfetch_unbind_buffer() *must* be called from inside the response callback. + + The usual code sequence to bind a different buffer in the response + callback might look like this: + + void response_callback(const sfetch_response_t* response) { + if (response.fetched) { + ... + // switch to a different buffer (in the FETCHED state it is + // guaranteed that the request has a buffer, otherwise it + // would have gone into the FAILED state + void* old_buf_ptr = sfetch_unbind_buffer(response.handle); + free(old_buf_ptr); + void* new_buf_ptr = malloc(new_buf_size); + sfetch_bind_buffer(response.handle, new_buf_ptr, new_buf_size); + } + if (response.finished) { + // unbind and free the currently associated buffer, + // the buffer pointer could be null if the request has failed + // NOTE that it is legal to call free() with a nullptr, + // this happens if the request failed to open its file + // and never goes into the OPENED state + void* buf_ptr = sfetch_unbind_buffer(response.handle); + free(buf_ptr); + } + } + + sfetch_desc_t sfetch_desc(void) + ------------------------------- + sfetch_desc() returns a copy of the sfetch_desc_t struct passed to + sfetch_setup(), with zero-initialized values replaced with + their default values. + + int sfetch_max_userdata_bytes(void) + ----------------------------------- + This returns the value of the SFETCH_MAX_USERDATA_UINT64 config + define, but in number of bytes (so SFETCH_MAX_USERDATA_UINT64*8). + + int sfetch_max_path(void) + ------------------------- + Returns the value of the SFETCH_MAX_PATH config define. + + + REQUEST STATES AND THE RESPONSE CALLBACK + ======================================== + A request goes through a number of states during its lifetime. Depending + on the current state of a request, it will be 'owned' either by the + "user-thread" (where the request was sent) or an IO thread. + + You can think of a request as "ping-ponging" between the IO thread and + user thread, any actual IO work is done on the IO thread, while + invocations of the response-callback happen on the user-thread. + + All state transitions and callback invocations happen inside the + sfetch_dowork() function. + + An active request goes through the following states: + + ALLOCATED (user-thread) + + The request has been allocated in sfetch_send() and is + waiting to be dispatched into its IO channel. When this + happens, the request will transition into the DISPATCHED state. + + DISPATCHED (IO thread) + + The request has been dispatched into its IO channel, and a + lane has been assigned to the request. + + If a buffer was provided in sfetch_send() the request will + immediately transition into the FETCHING state and start loading + data into the buffer. + + If no buffer was provided in sfetch_send(), the response + callback will be called with (response->dispatched == true), + so that the response callback can bind a buffer to the + request. Binding the buffer in the response callback makes + sense if the buffer isn't dynamically allocated, but instead + a pre-allocated buffer must be selected from the request's + channel and lane. + + Note that it isn't possible to get a file size in the response callback + which would help with allocating a buffer of the right size, this is + because it isn't possible in HTTP to query the file size before the + entire file is downloaded (...when the web server serves files compressed). + + If opening the file failed, the request will transition into + the FAILED state with the error code SFETCH_ERROR_FILE_NOT_FOUND. + + FETCHING (IO thread) + + While a request is in the FETCHING state, data will be loaded into + the user-provided buffer. + + If no buffer was provided, the request will go into the FAILED + state with the error code SFETCH_ERROR_NO_BUFFER. + + If a buffer was provided, but it is too small to contain the + fetched data, the request will go into the FAILED state with + error code SFETCH_ERROR_BUFFER_TOO_SMALL. + + If less data can be read from the file than expected, the request + will go into the FAILED state with error code SFETCH_ERROR_UNEXPECTED_EOF. + + If loading data into the provided buffer works as expected, the + request will go into the FETCHED state. + + FETCHED (user thread) + + The request goes into the FETCHED state either when the entire file + has been loaded into the provided buffer (when request.chunk_size == 0), + or a chunk has been loaded (and optionally decompressed) into the + buffer (when request.chunk_size > 0). + + The response callback will be called so that the user-code can + process the loaded data using the following sfetch_response_t struct members: + + - data.ptr: pointer to the start of fetched data + - data.size: the number of bytes in the provided buffer + - data_offset: the byte offset of the loaded data chunk in the + overall file (this is only set to a non-zero value in a streaming + scenario) + + Once all file data has been loaded, the 'finished' flag will be set + in the response callback's sfetch_response_t argument. + + After the user callback returns, and all file data has been loaded + (response.finished flag is set) the request has reached its end-of-life + and will be recycled. + + Otherwise, if there's still data to load (because streaming was + requested by providing a non-zero request.chunk_size), the request + will switch back to the FETCHING state to load the next chunk of data. + + Note that it is ok to associate a different buffer or buffer-size + with the request by calling sfetch_bind_buffer() in the response-callback. + + To check in the response callback for the FETCHED state, and + independently whether the request is finished: + + void response_callback(const sfetch_response_t* response) { + if (response->fetched) { + // request is in FETCHED state, the loaded data is available + // in .data.ptr, and the number of bytes that have been + // loaded in .data.size: + const void* data = response->data.ptr; + size_t num_bytes = response->data.size; + } + if (response->finished) { + // the finished flag is set either when all data + // has been loaded, the request has been cancelled, + // or the file operation has failed, this is where + // any required per-request cleanup work should happen + } + } + + + FAILED (user thread) + + A request will transition into the FAILED state in the following situations: + + - if the file doesn't exist or couldn't be opened for other + reasons (SFETCH_ERROR_FILE_NOT_FOUND) + - if no buffer is associated with the request in the FETCHING state + (SFETCH_ERROR_NO_BUFFER) + - if the provided buffer is too small to hold the entire file + (if request.chunk_size == 0), or the (potentially decompressed) + partial data chunk (SFETCH_ERROR_BUFFER_TOO_SMALL) + - if less bytes could be read from the file then expected + (SFETCH_ERROR_UNEXPECTED_EOF) + - if a request has been cancelled via sfetch_cancel() + (SFETCH_ERROR_CANCELLED) + + The response callback will be called once after a request goes into + the FAILED state, with the 'response->finished' and + 'response->failed' flags set to true. + + This gives the user-code a chance to cleanup any resources associated + with the request. + + To check for the failed state in the response callback: + + void response_callback(const sfetch_response_t* response) { + if (response->failed) { + // specifically check for the failed state... + } + // or you can do a catch-all check via the finished-flag: + if (response->finished) { + if (response->failed) { + // if more detailed error handling is needed: + switch (response->error_code) { + ... + } + } + } + } + + PAUSED (user thread) + + A request will transition into the PAUSED state after user-code + calls the function sfetch_pause() on the request's handle. Usually + this happens from within the response-callback in streaming scenarios + when the data streaming needs to wait for a data decoder (like + a video/audio player) to catch up. + + While a request is in PAUSED state, the response-callback will be + called in each sfetch_dowork(), so that the user-code can either + continue the request by calling sfetch_continue(), or cancel + the request by calling sfetch_cancel(). + + When calling sfetch_continue() on a paused request, the request will + transition into the FETCHING state. Otherwise if sfetch_cancel() is + called, the request will switch into the FAILED state. + + To check for the PAUSED state in the response callback: + + void response_callback(const sfetch_response_t* response) { + if (response->paused) { + // we can check here whether the request should + // continue to load data: + if (should_continue(response->handle)) { + sfetch_continue(response->handle); + } + } + } + + + CHUNK SIZE AND HTTP COMPRESSION + =============================== + TL;DR: for streaming scenarios, the provided chunk-size must be smaller + than the provided buffer-size because the web server may decide to + serve the data compressed and the chunk-size must be given in 'compressed + bytes' while the buffer receives 'uncompressed bytes'. It's not possible + in HTTP to query the uncompressed size for a compressed download until + that download has finished. + + With vanilla HTTP, it is not possible to query the actual size of a file + without downloading the entire file first (the Content-Length response + header only provides the compressed size). Furthermore, for HTTP + range-requests, the range is given on the compressed data, not the + uncompressed data. So if the web server decides to serve the data + compressed, the content-length and range-request parameters don't + correspond to the uncompressed data that's arriving in the sokol-fetch + buffers, and there's no way from JS or WASM to either force uncompressed + downloads (e.g. by setting the Accept-Encoding field), or access the + compressed data. + + This has some implications for sokol_fetch.h, most notably that buffers + can't be provided in the exactly right size, because that size can't + be queried from HTTP before the data is actually downloaded. + + When downloading whole files at once, it is basically expected that you + know the maximum files size upfront through other means (for instance + through a separate meta-data-file which contains the file sizes and + other meta-data for each file that needs to be loaded). + + For streaming downloads the situation is a bit more complicated. These + use HTTP range-requests, and those ranges are defined on the (potentially) + compressed data which the JS/WASM side doesn't have access to. However, + the JS/WASM side only ever sees the uncompressed data, and it's not possible + to query the uncompressed size of a range request before that range request + has finished. + + If the provided buffer is too small to contain the uncompressed data, + the request will fail with error code SFETCH_ERROR_BUFFER_TOO_SMALL. + + + CHANNELS AND LANES + ================== + Channels and lanes are (somewhat artificial) concepts to manage + parallelization, prioritization and rate-limiting. + + Channels can be used to parallelize message processing for better 'pipeline + throughput', and to prioritize requests: user-code could reserve one + channel for streaming downloads which need to run in parallel to other + requests, another channel for "regular" downloads and yet another + high-priority channel which would only be used for small files which need + to start loading immediately. + + Each channel comes with its own IO thread and message queues for pumping + messages in and out of the thread. The channel where a request is + processed is selected manually when sending a message: + + sfetch_send(&(sfetch_request_t){ + .path = "my_file.txt", + .callback = my_response_callback, + .channel = 2 + }); + + The number of channels is configured at startup in sfetch_setup() and + cannot be changed afterwards. + + Channels are completely separate from each other, and a request will + never "hop" from one channel to another. + + Each channel consists of a fixed number of "lanes" for automatic rate + limiting: + + When a request is sent to a channel via sfetch_send(), a "free lane" will + be picked and assigned to the request. The request will occupy this lane + for its entire life time (also while it is paused). If all lanes of a + channel are currently occupied, new requests will wait until a + lane becomes unoccupied. + + Since the number of channels and lanes is known upfront, it is guaranteed + that there will never be more than "num_channels * num_lanes" requests + in flight at any one time. + + This guarantee eliminates unexpected load- and memory-spikes when + many requests are sent in very short time, and it allows to pre-allocate + a fixed number of memory buffers which can be reused for the entire + "lifetime" of a sokol-fetch context. + + In the most simple scenario - when a maximum file size is known - buffers + can be statically allocated like this: + + uint8_t buffer[NUM_CHANNELS][NUM_LANES][MAX_FILE_SIZE]; + + Then in the user callback pick a buffer by channel and lane, + and associate it with the request like this: + + void response_callback(const sfetch_response_t* response) { + if (response->dispatched) { + void* ptr = buffer[response->channel][response->lane]; + sfetch_bind_buffer(response->handle, ptr, MAX_FILE_SIZE); + } + ... + } + + + NOTES ON OPTIMIZING PIPELINE LATENCY AND THROUGHPUT + =================================================== + With the default configuration of 1 channel and 1 lane per channel, + sokol_fetch.h will appear to have a shockingly bad loading performance + if several files are loaded. + + This has two reasons: + + (1) all parallelization when loading data has been disabled. A new + request will only be processed, when the last request has finished. + + (2) every invocation of the response-callback adds one frame of latency + to the request, because callbacks will only be called from within + sfetch_dowork() + + sokol-fetch takes a few shortcuts to improve step (2) and reduce + the 'inherent latency' of a request: + + - if a buffer is provided upfront, the response-callback won't be + called in the DISPATCHED state, but start right with the FETCHED state + where data has already been loaded into the buffer + + - there is no separate CLOSED state where the callback is invoked + separately when loading has finished (or the request has failed), + instead the finished and failed flags will be set as part of + the last FETCHED invocation + + This means providing a big-enough buffer to fit the entire file is the + best case, the response callback will only be called once, ideally in + the next frame (or two calls to sfetch_dowork()). + + If no buffer is provided upfront, one frame of latency is added because + the response callback needs to be invoked in the DISPATCHED state so that + the user code can bind a buffer. + + This means the best case for a request without an upfront-provided + buffer is 2 frames (or 3 calls to sfetch_dowork()). + + That's about what can be done to improve the latency for a single request, + but the really important step is to improve overall throughput. If you + need to load thousands of files you don't want that to be completely + serialized. + + The most important action to increase throughput is to increase the + number of lanes per channel. This defines how many requests can be + 'in flight' on a single channel at the same time. The guiding decision + factor for how many lanes you can "afford" is the memory size you want + to set aside for buffers. Each lane needs its own buffer so that + the data loaded for one request doesn't scribble over the data + loaded for another request. + + Here's a simple example of sending 4 requests without upfront buffer + on a channel with 1, 2 and 4 lanes, each line is one frame: + + 1 LANE (8 frames): + Lane 0: + ------------- + REQ 0 DISPATCHED + REQ 0 FETCHED + REQ 1 DISPATCHED + REQ 1 FETCHED + REQ 2 DISPATCHED + REQ 2 FETCHED + REQ 3 DISPATCHED + REQ 3 FETCHED + + Note how the request don't overlap, so they can all use the same buffer. + + 2 LANES (4 frames): + Lane 0: Lane 1: + ------------------------------------ + REQ 0 DISPATCHED REQ 1 DISPATCHED + REQ 0 FETCHED REQ 1 FETCHED + REQ 2 DISPATCHED REQ 3 DISPATCHED + REQ 2 FETCHED REQ 3 FETCHED + + This reduces the overall time to 4 frames, but now you need 2 buffers so + that requests don't scribble over each other. + + 4 LANES (2 frames): + Lane 0: Lane 1: Lane 2: Lane 3: + ---------------------------------------------------------------------------- + REQ 0 DISPATCHED REQ 1 DISPATCHED REQ 2 DISPATCHED REQ 3 DISPATCHED + REQ 0 FETCHED REQ 1 FETCHED REQ 2 FETCHED REQ 3 FETCHED + + Now we're down to the same 'best-case' latency as sending a single + request. + + Apart from the memory requirements for the streaming buffers (which is + under your control), you can be generous with the number of lanes, + they don't add any processing overhead. + + The last option for tweaking latency and throughput is channels. Each + channel works independently from other channels, so while one + channel is busy working through a large number of requests (or one + very long streaming download), you can set aside a high-priority channel + for requests that need to start as soon as possible. + + On platforms with threading support, each channel runs on its own + thread, but this is mainly an implementation detail to work around + the traditional blocking file IO functions, not for performance reasons. + + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + ... + sfetch_setup(&(sfetch_desc_t){ + // ... + .allocator = { + .alloc_fn = my_alloc, + .free_fn = my_free, + .user_data = ..., + } + }); + ... + + If no overrides are provided, malloc and free will be used. + + This only affects memory allocation calls done by sokol_fetch.h + itself though, not any allocations in OS libraries. + + Memory allocation will only happen on the same thread where sfetch_setup() + was called, so you don't need to worry about thread-safety. + + + ERROR REPORTING AND LOGGING + =========================== + To get any logging information at all you need to provide a logging callback in the setup call, + the easiest way is to use sokol_log.h: + + #include "sokol_log.h" + + sfetch_setup(&(sfetch_desc_t){ + // ... + .logger.func = slog_func + }); + + To override logging with your own callback, first write a logging function like this: + + void my_log(const char* tag, // e.g. 'sfetch' + uint32_t log_level, // 0=panic, 1=error, 2=warn, 3=info + uint32_t log_item_id, // SFETCH_LOGITEM_* + const char* message_or_null, // a message string, may be nullptr in release mode + uint32_t line_nr, // line number in sokol_fetch.h + const char* filename_or_null, // source filename, may be nullptr in release mode + void* user_data) + { + ... + } + + ...and then setup sokol-fetch like this: + + sfetch_setup(&(sfetch_desc_t){ + .logger = { + .func = my_log, + .user_data = my_user_data, + } + }); + + The provided logging function must be reentrant (e.g. be callable from + different threads). + + If you don't want to provide your own custom logger it is highly recommended to use + the standard logger in sokol_log.h instead, otherwise you won't see any warnings or + errors. + + + FUTURE PLANS / V2.0 IDEA DUMP + ============================= + - An optional polling API (as alternative to callback API) + - Move buffer-management into the API? The "manual management" + can be quite tricky especially for dynamic allocation scenarios, + API support for buffer management would simplify cases like + preventing that requests scribble over each other's buffers, or + an automatic garbage collection for dynamically allocated buffers, + or automatically falling back to dynamic allocation if static + buffers aren't big enough. + - Pluggable request handlers to load data from other "sources" + (especially HTTP downloads on native platforms via e.g. libcurl + would be useful) + - I'm currently not happy how the user-data block is handled, this + should getting and updating the user-data should be wrapped by + API functions (similar to bind/unbind buffer) + + + LICENSE + ======= + zlib/libpng license + + Copyright (c) 2019 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

For instance + here is an example from the ozz-skin-sapp.c sample shader which samples an + RGBA32F texture with skinning matrices in the vertex shader: + + ```glsl + @image_sample_type joint_tex unfilterable_float + uniform texture2D joint_tex; + @sampler_type smp nonfiltering + uniform sampler smp; + ``` + + This will result in SG_IMAGESAMPLETYPE_UNFILTERABLE_FLOAT and + SG_SAMPLERTYPE_NONFILTERING being written to the code-generated + sg_shader_desc struct. + + + ON VERTEX FORMATS + ================= + Sokol-gfx implements the same strict mapping rules from CPU-side + vertex component formats to GPU-side vertex input data types: + + - float and packed normalized CPU-side formats must be used as + floating point base type in the vertex shader + - packed signed-integer CPU-side formats must be used as signed + integer base type in the vertex shader + - packed unsigned-integer CPU-side formats must be used as unsigned + integer base type in the vertex shader + + These mapping rules are enforced by the sokol-gfx validation layer, + but only when sufficient reflection information is provided in + `sg_shader_desc.attrs[].base_type`. This is the case when sokol-shdc + is used, otherwise the default base_type will be SG_SHADERATTRBASETYPE_UNDEFINED + which causes the sokol-gfx validation check to be skipped (of course you + can also provide the per-attribute base type information manually when + not using sokol-shdc). + + The detailed mapping rules from SG_VERTEXFORMAT_* to GLSL data types + are as follows: + + - FLOAT[*] => float, vec* + - BYTE4N => vec* (scaled to -1.0 .. +1.0) + - UBYTE4N => vec* (scaled to 0.0 .. +1.0) + - SHORT[*]N => vec* (scaled to -1.0 .. +1.0) + - USHORT[*]N => vec* (scaled to 0.0 .. +1.0) + - INT[*] => int, ivec* + - UINT[*] => uint, uvec* + - BYTE4 => int* + - UBYTE4 => uint* + - SHORT[*] => int* + - USHORT[*] => uint* + + NOTE that sokol-gfx only provides vertex formats with sizes of a multiple + of 4 (e.g. BYTE4N but not BYTE2N). This is because vertex components must + be 4-byte aligned anyway. + + + UNIFORM DATA LAYOUT: + ==================== + NOTE: if you use the sokol-shdc shader compiler tool, you don't need to worry + about the following details. + + The data that's passed into the sg_apply_uniforms() function must adhere to + specific layout rules so that the GPU shader finds the uniform block + items at the right offset. + + For the D3D11 and Metal backends, sokol-gfx only cares about the size of uniform + blocks, but not about the internal layout. The data will just be copied into + a uniform/constant buffer in a single operation and it's up you to arrange the + CPU-side layout so that it matches the GPU side layout. This also means that with + the D3D11 and Metal backends you are not limited to a 'cross-platform' subset + of uniform variable types. + + If you ever only use one of the D3D11, Metal *or* WebGPU backend, you can stop reading here. + + For the GL backends, the internal layout of uniform blocks matters though, + and you are limited to a small number of uniform variable types. This is + because sokol-gfx must be able to locate the uniform block members in order + to upload them to the GPU with glUniformXXX() calls. + + To describe the uniform block layout to sokol-gfx, the following information + must be passed to the sg_make_shader() call in the sg_shader_desc struct: + + - a hint about the used packing rule (either SG_UNIFORMLAYOUT_NATIVE or + SG_UNIFORMLAYOUT_STD140) + - a list of the uniform block members types in the correct order they + appear on the CPU side + + For example if the GLSL shader has the following uniform declarations: + + uniform mat4 mvp; + uniform vec2 offset0; + uniform vec2 offset1; + uniform vec2 offset2; + + ...and on the CPU side, there's a similar C struct: + + typedef struct { + float mvp[16]; + float offset0[2]; + float offset1[2]; + float offset2[2]; + } params_t; + + ...the uniform block description in the sg_shader_desc must look like this: + + sg_shader_desc desc = { + .vs.uniform_blocks[0] = { + .size = sizeof(params_t), + .layout = SG_UNIFORMLAYOUT_NATIVE, // this is the default and can be omitted + .uniforms = { + // order must be the same as in 'params_t': + [0] = { .name = "mvp", .type = SG_UNIFORMTYPE_MAT4 }, + [1] = { .name = "offset0", .type = SG_UNIFORMTYPE_VEC2 }, + [2] = { .name = "offset1", .type = SG_UNIFORMTYPE_VEC2 }, + [3] = { .name = "offset2", .type = SG_UNIFORMTYPE_VEC2 }, + } + } + }; + + With this information sokol-gfx can now compute the correct offsets of the data items + within the uniform block struct. + + The SG_UNIFORMLAYOUT_NATIVE packing rule works fine if only the GL backends are used, + but for proper D3D11/Metal/GL a subset of the std140 layout must be used which is + described in the next section: + + + CROSS-BACKEND COMMON UNIFORM DATA LAYOUT + ======================================== + For cross-platform / cross-3D-backend code it is important that the same uniform block + layout on the CPU side can be used for all sokol-gfx backends. To achieve this, + a common subset of the std140 layout must be used: + + - The uniform block layout hint in sg_shader_desc must be explicitly set to + SG_UNIFORMLAYOUT_STD140. + - Only the following GLSL uniform types can be used (with their associated sokol-gfx enums): + - float => SG_UNIFORMTYPE_FLOAT + - vec2 => SG_UNIFORMTYPE_FLOAT2 + - vec3 => SG_UNIFORMTYPE_FLOAT3 + - vec4 => SG_UNIFORMTYPE_FLOAT4 + - int => SG_UNIFORMTYPE_INT + - ivec2 => SG_UNIFORMTYPE_INT2 + - ivec3 => SG_UNIFORMTYPE_INT3 + - ivec4 => SG_UNIFORMTYPE_INT4 + - mat4 => SG_UNIFORMTYPE_MAT4 + - Alignment for those types must be as follows (in bytes): + - float => 4 + - vec2 => 8 + - vec3 => 16 + - vec4 => 16 + - int => 4 + - ivec2 => 8 + - ivec3 => 16 + - ivec4 => 16 + - mat4 => 16 + - Arrays are only allowed for the following types: vec4, int4, mat4. + + Note that the HLSL cbuffer layout rules are slightly different from the + std140 layout rules, this means that the cbuffer declarations in HLSL code + must be tweaked so that the layout is compatible with std140. + + The by far easiest way to tackle the common uniform block layout problem is + to use the sokol-shdc shader cross-compiler tool! + + + ON STORAGE BUFFERS + ================== + The two main purpose of storage buffers are: + + - to be populated by compute shaders with dynamically generated data + - for providing random-access data to all shader stages + + Storage buffers can be used to pass large amounts of random access structured + data from the CPU side to the shaders. They are similar to data textures, but are + more convenient to use both on the CPU and shader side since they can be accessed + in shaders as as a 1-dimensional array of struct items. + + Storage buffers are *NOT* supported on the following platform/backend combos: + + - macOS+GL (because storage buffers require GL 4.3, while macOS only goes up to GL 4.1) + - platforms which only support a GLES3.0 context (WebGL2 and iOS) + + To use storage buffers, the following steps are required: + + - write a shader which uses storage buffers (vertex- and fragment-shaders + can only read from storage buffers, while compute-shaders can both read + and write storage buffers) + - create one or more storage buffers via sg_make_buffer() with the + buffer type SG_BUFFERTYPE_STORAGEBUFFER + - when creating a shader via sg_make_shader(), populate the sg_shader_desc + struct with binding info (when using sokol-shdc, this step will be taken care + of automatically) + - which storage buffer bind slots on the vertex-, fragment- or compute-stage + are occupied + - whether the storage buffer on that bind slot is readonly (readonly + bindings are required for vertex- and fragment-shaders, and in compute + shaders the readonly flag is used to control hazard tracking in some + 3D backends) + + - when calling sg_apply_bindings(), apply the matching bind slots with the previously + created storage buffers + - ...and that's it. + + For more details, see the following backend-agnostic sokol samples: + + - simple vertex pulling from a storage buffer: + - C code: https://github.com/floooh/sokol-samples/blob/master/sapp/vertexpull-sapp.c + - shader: https://github.com/floooh/sokol-samples/blob/master/sapp/vertexpull-sapp.glsl + - instanced rendering via storage buffers (vertex- and instance-pulling): + - C code: https://github.com/floooh/sokol-samples/blob/master/sapp/instancing-pull-sapp.c + - shader: https://github.com/floooh/sokol-samples/blob/master/sapp/instancing-pull-sapp.glsl + - storage buffers both on the vertex- and fragment-stage: + - C code: https://github.com/floooh/sokol-samples/blob/master/sapp/sbuftex-sapp.c + - shader: https://github.com/floooh/sokol-samples/blob/master/sapp/sbuftex-sapp.glsl + - the Ozz animation sample rewritten to pull all rendering data from storage buffers: + - C code: https://github.com/floooh/sokol-samples/blob/master/sapp/ozz-storagebuffer-sapp.cc + - shader: https://github.com/floooh/sokol-samples/blob/master/sapp/ozz-storagebuffer-sapp.glsl + - the instancing sample modified to use compute shaders: + - C code: https://github.com/floooh/sokol-samples/blob/master/sapp/instancing-compute-sapp.c + - shader: https://github.com/floooh/sokol-samples/blob/master/sapp/instancing-compute-sapp.glsl + - the Compute Boids sample ported to sokol-gfx: + - C code: https://github.com/floooh/sokol-samples/blob/master/sapp/computeboids-sapp.c + - shader: https://github.com/floooh/sokol-samples/blob/master/sapp/computeboids-sapp.glsl + + ...also see the following backend-specific vertex pulling samples (those also don't use sokol-shdc): + + - D3D11: https://github.com/floooh/sokol-samples/blob/master/d3d11/vertexpulling-d3d11.c + - desktop GL: https://github.com/floooh/sokol-samples/blob/master/glfw/vertexpulling-glfw.c + - Metal: https://github.com/floooh/sokol-samples/blob/master/metal/vertexpulling-metal.c + - WebGPU: https://github.com/floooh/sokol-samples/blob/master/wgpu/vertexpulling-wgpu.c + + ...and the backend specific compute shader samples: + + - D3D11: https://github.com/floooh/sokol-samples/blob/master/d3d11/instancing-compute-d3d11.c + - desktop GL: https://github.com/floooh/sokol-samples/blob/master/glfw/instancing-compute-glfw.c + - Metal: https://github.com/floooh/sokol-samples/blob/master/metal/instancing-compute-metal.c + - WebGPU: https://github.com/floooh/sokol-samples/blob/master/wgpu/instancing-compute-wgpu.c + + Storage buffer shader authoring caveats when using sokol-shdc: + + - declare a read-only storage buffer interface block with `layout(binding=N) readonly buffer [name] { ... }` + (where 'N' is the index in `sg_bindings.storage_buffers[N]`) + - ...or a read/write storage buffer interface block with `layout(binding=N) buffer [name] { ... }` + - declare a struct which describes a single array item in the storage buffer interface block + - only put a single flexible array member into the storage buffer interface block + + E.g. a complete example in 'sokol-shdc GLSL': + + ```glsl + @vs + // declare a struct: + struct sb_vertex { + vec3 pos;

When a public API function is called, and + a trace hook callback has been installed for this function, the + callback will be invoked with the parameters and result of the function. + This is useful for things like debugging- and profiling-tools, or + keeping track of resource creation and destruction. + + To use the trace hook feature: + + --- Define SOKOL_TRACE_HOOKS before including the implementation. + + --- Setup an sg_trace_hooks structure with your callback function + pointers (keep all function pointers you're not interested + in zero-initialized), optionally set the user_data member + in the sg_trace_hooks struct. + + --- Install the trace hooks by calling sg_install_trace_hooks(), + the return value of this function is another sg_trace_hooks + struct which contains the previously set of trace hooks. + You should keep this struct around, and call those previous + functions pointers from your own trace callbacks for proper + chaining. + + As an example of how trace hooks are used, have a look at the + imgui/sokol_gfx_imgui.h header which implements a realtime + debugging UI for sokol_gfx.h on top of Dear ImGui. + + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + ... + sg_setup(&(sg_desc){ + // ... + .allocator = { + .alloc_fn = my_alloc, + .free_fn = my_free, + .user_data = ..., + } + }); + ... + + If no overrides are provided, malloc and free will be used. + + This only affects memory allocation calls done by sokol_gfx.h + itself though, not any allocations in OS libraries. + + + ERROR REPORTING AND LOGGING + =========================== + To get any logging information at all you need to provide a logging callback in the setup call + the easiest way is to use sokol_log.h: + + #include "sokol_log.h" + + sg_setup(&(sg_desc){ .logger.func = slog_func }); + + To override logging with your own callback, first write a logging function like this: + + void my_log(const char* tag, // e.g. 'sg' + uint32_t log_level, // 0=panic, 1=error, 2=warn, 3=info + uint32_t log_item_id, // SG_LOGITEM_* + const char* message_or_null, // a message string, may be nullptr in release mode + uint32_t line_nr, // line number in sokol_gfx.h + const char* filename_or_null, // source filename, may be nullptr in release mode + void* user_data) + { + ... + } + + ...and then setup sokol-gfx like this: + + sg_setup(&(sg_desc){ + .logger = { + .func = my_log, + .user_data = my_user_data, + } + }); + + The provided logging function must be reentrant (e.g. be callable from + different threads). + + If you don't want to provide your own custom logger it is highly recommended to use + the standard logger in sokol_log.h instead, otherwise you won't see any warnings or + errors. + + + COMMIT LISTENERS + ================ + It's possible to hook callback functions into sokol-gfx which are called from + inside sg_commit() in unspecified order. This is mainly useful for libraries + that build on top of sokol_gfx.h to be notified about the end/start of a frame. + + To add a commit listener, call: + + static void my_commit_listener(void* user_data) { + ... + } + + bool success = sg_add_commit_listener((sg_commit_listener){ + .func = my_commit_listener, + .user_data = ..., + }); + + The function returns false if the internal array of commit listeners is full, + or the same commit listener had already been added. + + If the function returns true, my_commit_listener() will be called each frame + from inside sg_commit(). + + By default, 1024 distinct commit listeners can be added, but this number + can be tweaked in the sg_setup() call: + + sg_setup(&(sg_desc){ + .max_commit_listeners = 2048, + }); + + An sg_commit_listener item is equal to another if both the function + pointer and user_data field are equal. + + To remove a commit listener: + + bool success = sg_remove_commit_listener((sg_commit_listener){ + .func = my_commit_listener, + .user_data = ..., + }); + + ...where the .func and .user_data field are equal to a previous + sg_add_commit_listener() call. The function returns true if the commit + listener item was found and removed, and false otherwise. + + + RESOURCE CREATION AND DESTRUCTION IN DETAIL + =========================================== + The 'vanilla' way to create resource objects is with the 'make functions': + + sg_buffer sg_make_buffer(const sg_buffer_desc* desc) + sg_image sg_make_image(const sg_image_desc* desc) + sg_sampler sg_make_sampler(const sg_sampler_desc* desc) + sg_shader sg_make_shader(const sg_shader_desc* desc) + sg_pipeline sg_make_pipeline(const sg_pipeline_desc* desc) + sg_attachments sg_make_attachments(const sg_attachments_desc* desc) + + This will result in one of three cases: + + 1. The returned handle is invalid. This happens when there are no more + free slots in the resource pool for this resource type. An invalid + handle is associated with the INVALID resource state, for instance: + + sg_buffer buf = sg_make_buffer(...) + if (sg_query_buffer_state(buf) == SG_RESOURCESTATE_INVALID) { + // buffer pool is exhausted + } + + 2. The returned handle is valid, but creating the underlying resource + has failed for some reason. This results in a resource object in the + FAILED state. The reason *why* resource creation has failed differ + by resource type. Look for log messages with more details. A failed + resource state can be checked with: + + sg_buffer buf = sg_make_buffer(...) + if (sg_query_buffer_state(buf) == SG_RESOURCESTATE_FAILED) { + // creating the resource has failed + } + + 3.

For instance when loading data + asynchronously from a slow data source, you may know what buffers and + textures are needed at an early stage of the loading process, but actually + loading the buffer or texture content can only be completed at a later time. + + For such situations, sokol-gfx resource objects can be created in two steps. + You can allocate a handle upfront with one of the 'alloc functions': + + sg_buffer sg_alloc_buffer(void) + sg_image sg_alloc_image(void) + sg_sampler sg_alloc_sampler(void) + sg_shader sg_alloc_shader(void) + sg_pipeline sg_alloc_pipeline(void) + sg_attachments sg_alloc_attachments(void) + + This will return a handle with the underlying resource object in the + ALLOC state: + + sg_image img = sg_alloc_image(); + if (sg_query_image_state(img) == SG_RESOURCESTATE_ALLOC) { + // allocating an image handle has succeeded, otherwise + // the image pool is full + } + + Such an 'incomplete' handle can be used in most sokol-gfx rendering functions + without doing any harm, sokol-gfx will simply skip any rendering operation + that involve resources which are not in VALID state. + + At a later time (for instance once the texture has completed loading + asynchronously), the resource creation can be completed by calling one of + the 'init functions', those functions take an existing resource handle and + 'desc struct': + + void sg_init_buffer(sg_buffer buf, const sg_buffer_desc* desc) + void sg_init_image(sg_image img, const sg_image_desc* desc) + void sg_init_sampler(sg_sampler smp, const sg_sampler_desc* desc) + void sg_init_shader(sg_shader shd, const sg_shader_desc* desc) + void sg_init_pipeline(sg_pipeline pip, const sg_pipeline_desc* desc) + void sg_init_attachments(sg_attachments atts, const sg_attachments_desc* desc) + + The init functions expect a resource in ALLOC state, and after the function + returns, the resource will be either in VALID or FAILED state.

Same when trying to create + an attachments object with invalid image objects. + + + WEBGPU CAVEATS + ============== + For a general overview and design notes of the WebGPU backend see: + + https://floooh.github.io/2023/10/16/sokol-webgpu.html + + In general, don't expect an automatic speedup when switching from the WebGL2 + backend to the WebGPU backend. Some WebGPU functions currently actually + have a higher CPU overhead than similar WebGL2 functions, leading to the + paradoxical situation that some WebGPU code may be slower than similar WebGL2 + code. + + - when writing WGSL shader code by hand, a specific bind-slot convention + must be used: + + All uniform block structs must use `@group(0)` and bindings in the + range 0..15 + + @group(0) @binding(0..15) + + All textures, samplers and storage buffers must use `@group(1)` and + bindings must be in the range 0..127: + + @group(1) @binding(0..127) + + Note that the number of texture, sampler and storage buffer bindings + is still limited despite the large bind range: + + - up to 16 textures and sampler across all shader stages + - up to 8 storage buffers across all shader stages + + If you use sokol-shdc to generate WGSL shader code, you don't need to worry + about the above binding conventions since sokol-shdc. + + - The sokol-gfx WebGPU backend uses the sg_desc.uniform_buffer_size item + to allocate a single per-frame uniform buffer which must be big enough + to hold all data written by sg_apply_uniforms() during a single frame, + including a worst-case 256-byte alignment (e.g. each sg_apply_uniform + call will cost at least 256 bytes of uniform buffer size). The default size + is 4 MB, which is enough for 16384 sg_apply_uniform() calls per + frame (assuming the uniform data 'payload' is less than 256 bytes + per call). These rules are the same as for the Metal backend, so if + you are already using the Metal backend you'll be fine. + + - sg_apply_bindings(): the sokol-gfx WebGPU backend implements a bindgroup + cache to prevent excessive creation and destruction of BindGroup objects + when calling sg_apply_bindings(). The number of slots in the bindgroups + cache is defined in sg_desc.wgpu_bindgroups_cache_size when calling + sg_setup. The cache size must be a power-of-2 number, with the default being + 1024. The bindgroups cache behaviour can be observed by calling the new + function sg_query_frame_stats(), where the following struct items are + of interest: + + .wgpu.num_bindgroup_cache_hits + .wgpu.num_bindgroup_cache_misses + .wgpu.num_bindgroup_cache_collisions + .wgpu_num_bindgroup_cache_invalidates + .wgpu.num_bindgroup_cache_vs_hash_key_mismatch + + The value to pay attention to is `.wgpu.num_bindgroup_cache_collisions`, + if this number is consistently higher than a few percent of the + .wgpu.num_set_bindgroup value, it might be a good idea to bump the + bindgroups cache size to the next power-of-2. + + - sg_apply_viewport(): WebGPU currently has a unique restriction that viewport + rectangles must be contained entirely within the framebuffer. As a shitty + workaround sokol_gfx.h will clip incoming viewport rectangles against + the framebuffer, but this will distort the clipspace-to-screenspace mapping. + There's no proper way to handle this inside sokol_gfx.h, this must be fixed + in a future WebGPU update (see: https://github.com/gpuweb/gpuweb/issues/373 + and https://github.com/gpuweb/gpuweb/pull/5025) + + - The sokol shader compiler generally adds `diagnostic(off, derivative_uniformity);` + into the WGSL output. Currently only the Chrome WebGPU implementation seems + to recognize this. + + - Likewise, the following sokol-gfx pixel formats are not supported in WebGPU: + R16, R16SN, RG16, RG16SN, RGBA16, RGBA16SN. + Unlike unsupported vertex formats, unsupported pixel formats can be queried + in cross-backend code via sg_query_pixel_format() though. + + - The Emscripten WebGPU shim currently doesn't support the Closure minification + post-link-step (e.g. currently the emcc argument '--closure 1' or '--closure 2' + will generate broken Javascript code. + + - sokol-gfx requires the WebGPU device feature `depth32float-stencil8` to be enabled + (this should be widely supported) + + - sokol-gfx expects that the WebGPU device feature `float32-filterable` to *not* be + enabled (since this would exclude all iOS devices) + + + LICENSE + ======= + zlib/libpng license + + Copyright (c) 2018 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

This + allows to mix/interleave sokol-gl rendering with other render operations. + + Layered rendering is controlled through two functions: + + sgl_layer(int layer_id) + sgl_draw_layer(int layer_id) + + (and the context-variant sgl_draw_layer(): sgl_context_draw_layer() + + The sgl_layer() function sets the 'current layer', any sokol-gl calls + which internally record draw commands will also store the current layer + in the draw command, and later in a sokol-gfx render pass, a call + to sgl_draw_layer() will only render the draw commands that have + a matching layer. + + The default layer is '0', this is active after sokol-gl setup, and + is also restored at the start of a new frame (but *not* by calling + sgl_defaults()). + + NOTE that calling sgl_draw() is equivalent with sgl_draw_layer(0) + (in general you should either use either use sgl_draw() or + sgl_draw_layer() in an application, but not both). + + WORKING WITH CONTEXTS: + ====================== + If you want to render to more than one sokol-gfx render pass you need to + work with additional sokol-gl context objects (one context object for + each offscreen rendering pass, in addition to the implicitly created + 'default context'. + + All sokol-gl state is tracked per context, and there is always a "current + context" (with the notable exception that the currently set context is + destroyed, more on that later). + + Using multiple contexts can also be useful if you only render in + a single pass, but want to maintain multiple independent "state buckets". + + To create new context object, call: + + sgl_context ctx = sgl_make_context(&(sgl_context_desc){ + .max_vertices = ..., // default: 64k + .max_commands = ..., // default: 16k + .color_format = ..., + .depth_format = ..., + .sample_count = ..., + }); + + The color_format, depth_format and sample_count items must be compatible + with the render pass the sgl_draw() or sgL_context_draw() function + will be called in. + + Creating a context does *not* make the context current. To do this, call: + + sgl_set_context(ctx); + + The currently active context will implicitly be used by most sokol-gl functions + which don't take an explicit context handle as argument. + + To switch back to the default context, pass the global constant SGL_DEFAULT_CONTEXT: + + sgl_set_context(SGL_DEFAULT_CONTEXT); + + ...or alternatively use the function sgl_default_context() instead of the + global constant: + + sgl_set_context(sgl_default_context()); + + To get the currently active context, call: + + sgl_context cur_ctx = sgl_get_context(); + + The following functions exist in two variants, one which use the currently + active context (set with sgl_set_context()), and another version which + takes an explicit context handle instead: + + sgl_make_pipeline() vs sgl_context_make_pipeline() + sgl_error() vs sgl_context_error(); + sgl_draw() vs sgl_context_draw(); + + Except for using the currently active context versus a provided context + handle, the two variants are exactlyidentical, e.g. the following + code sequences do the same thing: + + sgl_set_context(ctx); + sgl_pipeline pip = sgl_make_pipeline(...); + sgl_error_t err = sgl_error(); + sgl_draw(); + + vs + + sgl_pipeline pip = sgl_context_make_pipeline(ctx, ...); + sgl_error_t err = sgl_context_error(ctx); + sgl_context_draw(ctx); + + Destroying the currently active context is a 'soft error'. All following + calls which require a currently active context will silently fail, + and sgl_error() will return SGL_ERROR_NO_CONTEXT. + + UNDER THE HOOD: + =============== + sokol_gl.h works by recording vertex data and rendering commands into + memory buffers, and then drawing the recorded commands via sokol_gfx.h + + The only functions which call into sokol_gfx.h are: + - sgl_setup() + - sgl_shutdown() + - sgl_draw() (and variants) + + sgl_setup() must be called after initializing sokol-gfx. + sgl_shutdown() must be called before shutting down sokol-gfx. + sgl_draw() must be called once per frame inside a sokol-gfx render pass. + + All other sokol-gl function can be called anywhere in a frame, since + they just record data into memory buffers owned by sokol-gl. + + What happens in: + + sgl_setup(): + Unique resources shared by all contexts are created: + - a shader object (using embedded shader source or byte code) + - an 8x8 white default texture + The default context is created, which involves: + - 3 memory buffers are created, one for vertex data, + one for uniform data, and one for commands + - a dynamic vertex buffer is created + - the default sgl_pipeline object is created, which involves + creating 5 sg_pipeline objects + + One vertex is 24 bytes: + - float3 position + - float2 texture coords + - uint32_t color + + One uniform block is 128 bytes: + - mat4 model-view-projection matrix + - mat4 texture matrix + + One draw command is ca. 24 bytes for the actual + command code plus command arguments. + + Each sgl_end() consumes one command, and one uniform block + (only when the matrices have changed). + The required size for one sgl_begin/end pair is (at most): + + (152 + 24 * num_verts) bytes + + sgl_shutdown(): + - all sokol-gfx resources (buffer, shader, default-texture and + all pipeline objects) are destroyed + - the 3 memory buffers are freed + + sgl_draw() (and variants) + - copy all recorded vertex data into the dynamic sokol-gfx buffer + via a call to sg_update_buffer() + - for each recorded command: + - if the layer number stored in the command doesn't match + the layer that's to be rendered, skip to the next + command + - if it's a viewport command, call sg_apply_viewport() + - if it's a scissor-rect command, call sg_apply_scissor_rect() + - if it's a draw command: + - depending on what has changed since the last draw command, + call sg_apply_pipeline(), sg_apply_bindings() and + sg_apply_uniforms() + - finally call sg_draw() + + All other functions only modify the internally tracked state, add + data to the vertex, uniform and command buffers, or manipulate + the matrix stack. + + ON DRAW COMMAND MERGING + ======================= + Not every call to sgl_end() will automatically record a new draw command. + If possible, the previous draw command will simply be extended, + resulting in fewer actual draw calls later in sgl_draw(). + + A draw command will be merged with the previous command if "no relevant + state has changed" since the last sgl_end(), meaning: + + - no calls to sgl_viewport() and sgl_scissor_rect() + - the primitive type hasn't changed + - the primitive type isn't a 'strip type' (no line or triangle strip) + - the pipeline state object hasn't changed + - the current layer hasn't changed + - none of the matrices has changed + - none of the texture state has changed + + Merging a draw command simply means that the number of vertices + to render in the previous draw command will be incremented by the + number of vertices in the new draw command. + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + ... + sgl_setup(&(sgl_desc_t){ + // ... + .allocator = { + .alloc_fn = my_alloc, + .free_fn = my_free, + .user_data = ...; + } + }); + ... + + If no overrides are provided, malloc and free will be used. + + + ERROR REPORTING AND LOGGING + =========================== + To get any logging information at all you need to provide a logging callback in the setup call, + the easiest way is to use sokol_log.h: + + #include "sokol_log.h" + + sgl_setup(&(sgl_desc_t){ + // ... + .logger.func = slog_func + }); + + To override logging with your own callback, first write a logging function like this: + + void my_log(const char* tag, // e.g. 'sgl' + uint32_t log_level, // 0=panic, 1=error, 2=warn, 3=info + uint32_t log_item_id, // SGL_LOGITEM_* + const char* message_or_null, // a message string, may be nullptr in release mode + uint32_t line_nr, // line number in sokol_gl.h + const char* filename_or_null, // source filename, may be nullptr in release mode + void* user_data) + { + ... + } + + ...and then setup sokol-gl like this: + + sgl_setup(&(sgl_desc_t){ + .logger = { + .func = my_log, + .user_data = my_user_data, + } + }); + + The provided logging function must be reentrant (e.g. be callable from + different threads). + + If you don't want to provide your own custom logger it is highly recommended to use + the standard logger in sokol_log.h instead, otherwise you won't see any warnings or + errors. + + + LICENSE + ======= + zlib/libpng license + + Copyright (c) 2018 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

+ uint16_t indices[4096]; + + sshape_buffer_t buf = { + .vertices = { + .buffer = SSHAPE_RANGE(vertices), + }, + .indices = { + .buffer = SSHAPE_RANGE(indices), + } + }; + ``` + + To find out how big those memory buffers must be (in case you want + to allocate dynamically) call the following functions: + + ```c + sshape_sizes_t sshape_plane_sizes(uint32_t tiles); + sshape_sizes_t sshape_box_sizes(uint32_t tiles); + sshape_sizes_t sshape_sphere_sizes(uint32_t slices, uint32_t stacks); + sshape_sizes_t sshape_cylinder_sizes(uint32_t slices, uint32_t stacks); + sshape_sizes_t sshape_torus_sizes(uint32_t sides, uint32_t rings); + ``` + + The returned sshape_sizes_t struct contains vertex- and index-counts + as well as the equivalent buffer sizes in bytes. For instance: + + ```c + sshape_sizes_t sizes = sshape_sphere_sizes(36, 12); + uint32_t num_vertices = sizes.vertices.num; + uint32_t num_indices = sizes.indices.num; + uint32_t vertex_buffer_size = sizes.vertices.size; + uint32_t index_buffer_size = sizes.indices.size; + ``` + + With the sshape_buffer_t struct that was setup earlier, call any + of the shape-builder functions: + + ```c + sshape_buffer_t sshape_build_plane(const sshape_buffer_t* buf, const sshape_plane_t* params); + sshape_buffer_t sshape_build_box(const sshape_buffer_t* buf, const sshape_box_t* params); + sshape_buffer_t sshape_build_sphere(const sshape_buffer_t* buf, const sshape_sphere_t* params); + sshape_buffer_t sshape_build_cylinder(const sshape_buffer_t* buf, const sshape_cylinder_t* params); + sshape_buffer_t sshape_build_torus(const sshape_buffer_t* buf, const sshape_torus_t* params); + ``` + + Note how the sshape_buffer_t struct is both an input value and the + return value. This can be used to append multiple shapes into the + same vertex- and index-buffers (more on this later). + + The second argument is a struct which holds creation parameters. + + For instance to build a sphere with radius 2, 36 "cake slices" and 12 stacks: + + ```c + sshape_buffer_t buf = ...; + buf = sshape_build_sphere(&buf, &(sshape_sphere_t){ + .radius = 2.0f, + .slices = 36, + .stacks = 12, + }); + ``` + + If the provided buffers are big enough to hold all generated vertices and + indices, the "valid" field in the result will be true: + + ```c + assert(buf.valid); + ``` + + The shape creation parameters have "useful defaults", refer to the + actual C struct declarations below to look up those defaults. + + You can also provide additional creation parameters, like a common vertex + color, a debug-helper to randomize colors, tell the shape builder function + to merge the new shape with the previous shape into the same draw-element-range, + or a 4x4 transform matrix to move, rotate and scale the generated vertices: + + ```c + sshape_buffer_t buf = ...; + buf = sshape_build_sphere(&buf, &(sshape_sphere_t){ + .radius = 2.0f, + .slices = 36, + .stacks = 12, + // merge with previous shape into a single element-range + .merge = true, + // set vertex color to red+opaque + .color = sshape_color_4f(1.0f, 0.0f, 0.0f, 1.0f), + // set position to y = 2.0 + .transform = { + .m = { + { 1.0f, 0.0f, 0.0f, 0.0f }, + { 0.0f, 1.0f, 0.0f, 0.0f }, + { 0.0f, 0.0f, 1.0f, 0.0f }, + { 0.0f, 2.0f, 0.0f, 1.0f }, + } + } + }); + assert(buf.valid); + ``` + + The following helper functions can be used to build a packed + color value or to convert from external matrix types: + + ```c + uint32_t sshape_color_4f(float r, float g, float b, float a); + uint32_t sshape_color_3f(float r, float g, float b); + uint32_t sshape_color_4b(uint8_t r, uint8_t g, uint8_t b, uint8_t a); + uint32_t sshape_color_3b(uint8_t r, uint8_t g, uint8_t b); + sshape_mat4_t sshape_mat4(const float m[16]); + sshape_mat4_t sshape_mat4_transpose(const float m[16]); + ``` + + After the shape builder function has been called, the following functions + are used to extract the build result for plugging into sokol_gfx.h: + + ```c + sshape_element_range_t sshape_element_range(const sshape_buffer_t* buf); + sg_buffer_desc sshape_vertex_buffer_desc(const sshape_buffer_t* buf); + sg_buffer_desc sshape_index_buffer_desc(const sshape_buffer_t* buf); + sg_vertex_buffer_layout_state sshape_vertex_buffer_layout_state(void); + sg_vertex_attr_state sshape_position_vertex_attr_state(void); + sg_vertex_attr_state sshape_normal_vertex_attr_state(void); + sg_vertex_attr_state sshape_texcoord_vertex_attr_state(void); + sg_vertex_attr_state sshape_color_vertex_attr_state(void); + ``` + + The sshape_element_range_t struct contains the base-index and number of + indices which can be plugged into the sg_draw() call: + + ```c + sshape_element_range_t elms = sshape_element_range(&buf); + ... + sg_draw(elms.base_element, elms.num_elements, 1); + ``` + + To create sokol-gfx vertex- and index-buffers from the generated + shape data: + + ```c + // create sokol-gfx vertex buffer + sg_buffer_desc vbuf_desc = sshape_vertex_buffer_desc(&buf);

This section +// includes documentation for each API function. +// +// Some important concepts to understand to use this library: +// +// Codepoint +// Characters are defined by unicode codepoints, e.g. 65 is +// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is +// the hiragana for "ma". +// +// Glyph +// A visual character shape (every codepoint is rendered as +// some glyph) +// +// Glyph index +// A font-specific integer ID representing a glyph +// +// Baseline +// Glyph shapes are defined relative to a baseline, which is the +// bottom of uppercase characters. Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since they different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// ADVANCED USAGE +// +// Quality: +// +// - Use the functions with Subpixel at the end to allow your characters +// to have subpixel positioning. Since the font is anti-aliased, not +// hinted, this is very import for quality. (This is not possible with +// baked fonts.) +// +// - Kerning is now supported, and if you're supporting subpixel rendering +// then kerning is worth using to give your text a polished look. +// +// Performance: +// +// - Convert Unicode codepoints to glyph indexes and operate on the glyphs; +// if you don't do this, stb_truetype is forced to do the conversion on +// every call. +// +// - There are a lot of memory allocations. We should modify it to take +// a temp buffer and allocate from the temp buffer (without freeing), +// should help performance a lot. +// +// NOTES +// +// The system uses the raw data found in the .ttf file without changing it +// and without building auxiliary data structures. This is a bit inefficient +// on little-endian systems (the data is big-endian), but assuming you're +// caching the bitmaps or glyph shapes this shouldn't be a big deal. +// +// It appears to be very hard to programmatically determine what font a +// given file is in a general way.

You only need to provide non-default + values here when rendering to render targets with different + pixel format attributes than the default framebuffer. + + --- Before starting to render text, optionally call sdtx_canvas() to + dynamically resize the virtual canvas. This is recommended when + rendering to a resizeable window. The virtual canvas size can + also be used to scale text in relation to the display resolution. + + Examples when using sokol-app: + + - to render characters at 8x8 'physical pixels': + + sdtx_canvas(sapp_width(), sapp_height()); + + - to render characters at 16x16 physical pixels: + + sdtx_canvas(sapp_width()/2.0f, sapp_height()/2.0f); + + Do *not* use integer math here, since this will not look nice + when the render target size isn't divisible by 2. + + --- Optionally define the origin for the character grid with: + + sdtx_origin(x, y); + + The provided coordinates are in character grid cells, not in + virtual canvas pixels. E.g. to set the origin to 2 character tiles + from the left and top border: + + sdtx_origin(2, 2); + + You can define fractions, e.g. to start rendering half + a character tile from the top-left corner: + + sdtx_origin(0.5f, 0.5f); + + --- Optionally set a different font by calling: + + sdtx_font(font_index) + + sokol-debugtext provides 8 font slots which can be populated + with the builtin fonts or with user-provided font data, so + 'font_index' must be a number from 0 to 7. + + --- Position the text cursor with one of the following calls.

X X . byte 6: 0x66 + . . . . . . . . byte 7: 0x00 + + A complete font consists of 256 characters, resulting in 2048 bytes for + the font data array (but note that the character codes 0..31 will never + be rendered). + + If you provide such a complete font data array, you can drop the .first_char + and .last_char initialization parameters since those default to 0 and 255, + note that you can also use the SDTX_RANGE() helper macro to build the + .data item: + + sdtx_setup(&sdtx_desc_t){ + .fonts = { + [0] = sdtx_font_kc853(), + [1] = { + .data = SDTX_RANGE(my_font_data) + } + } + }); + + If the font doesn't define all 256 character tiles, or you don't need an + entire 256-character font and want to save a couple of bytes, use the + .first_char and .last_char initialization parameters to define a sub-range. + For instance if the font only contains the characters between the Space + (ASCII code 32) and uppercase character 'Z' (ASCII code 90): + + sdtx_setup(&sdtx_desc_t){ + .fonts = { + [0] = sdtx_font_kc853(), + [1] = { + .data = SDTX_RANGE(my_font_data), + .first_char = 32, // could also write ' ' + .last_char = 90 // could also write 'Z' + } + } + }); + + Character tiles that haven't been defined in the font will be rendered + as a solid 8x8 quad. + + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + ... + sdtx_setup(&(sdtx_desc_t){ + // ... + .allocator = { + .alloc_fn = my_alloc, + .free_fn = my_free, + .user_data = ...; + } + }); + ... + + If no overrides are provided, malloc and free will be used. + + + ERROR REPORTING AND LOGGING + =========================== + To get any logging information at all you need to provide a logging callback in the setup call, + the easiest way is to use sokol_log.h: + + #include "sokol_log.h" + + sdtx_setup(&(sdtx_desc_t){ + // ... + .logger.func = slog_func + }); + + To override logging with your own callback, first write a logging function like this: + + void my_log(const char* tag, // e.g. 'sdtx' + uint32_t log_level, // 0=panic, 1=error, 2=warn, 3=info + uint32_t log_item_id, // SDTX_LOGITEM_* + const char* message_or_null, // a message string, may be nullptr in release mode + uint32_t line_nr, // line number in sokol_debugtext.h + const char* filename_or_null, // source filename, may be nullptr in release mode + void* user_data) + { + ... + } + + ...and then setup sokol-debugtext like this: + + sdtx_setup(&(sdtx_desc_t){ + .logger = { + .func = my_log, + .user_data = my_user_data, + } + }); + + The provided logging function must be reentrant (e.g. be callable from + different threads). + + If you don't want to provide your own custom logger it is highly recommended to use + the standard logger in sokol_log.h instead, otherwise you won't see any warnings or + errors. + + + LICENSE + ======= + zlib/libpng license + + Copyright (c) 2020 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

The web + version (emscripten/wasm) doesn't use POSIX-style threads, but instead + asynchronous Javascript calls chained together by callbacks. The actual + source code differences between the two approaches have been kept to + a minimum though. + + FEATURE OVERVIEW + ================ + + - Asynchronously load complete files, or stream files incrementally via + HTTP (on web platform), or the local file system (on native platforms) + + - Request / response-callback model, user code sends a request + to initiate a file-load, sokol_fetch.h calls the response callback + on the same thread when data is ready or user-code needs + to respond otherwise + + - Not limited to the main-thread or a single thread: A sokol-fetch + "context" can live on any thread, and multiple contexts + can operate side-by-side on different threads. + + - Memory management for data buffers is under full control of user code. + sokol_fetch.h won't allocate memory after it has been setup. + + - Automatic rate-limiting guarantees that only a maximum number of + requests is processed at any one time, allowing a zero-allocation + model, where all data is streamed into fixed-size, pre-allocated + buffers. + + - Active Requests can be paused, continued and cancelled from anywhere + in the user-thread which sent this request. + + + TL;DR EXAMPLE CODE + ================== + This is the most-simple example code to load a single data file with a + known maximum size: + + (1) initialize sokol-fetch with default parameters (but NOTE that the + default setup parameters provide a safe-but-slow "serialized" + operation). In order to see any logging output in case or errors + you should always provide a logging function + (such as 'slog_func' from sokol_log.h): + + sfetch_setup(&(sfetch_desc_t){ .logger.func = slog_func }); + + (2) send a fetch-request to load a file from the current directory + into a buffer big enough to hold the entire file content: + + static uint8_t buf[MAX_FILE_SIZE]; + + sfetch_send(&(sfetch_request_t){ + .path = "my_file.txt", + .callback = response_callback, + .buffer = { + .ptr = buf, + .size = sizeof(buf) + } + }); + + If 'buf' is a value (e.g. an array or struct item), the .buffer item can + be initialized with the SFETCH_RANGE() helper macro: + + sfetch_send(&(sfetch_request_t){ + .path = "my_file.txt", + .callback = response_callback, + .buffer = SFETCH_RANGE(buf) + }); + + (3) write a 'response-callback' function, this will be called whenever + the user-code must respond to state changes of the request + (most importantly when data has been loaded): + + void response_callback(const sfetch_response_t* response) { + if (response->fetched) { + // data has been loaded, and is available via the + // sfetch_range_t struct item 'data': + const void* ptr = response->data.ptr; + size_t num_bytes = response->data.size; + } + if (response->finished) { + // the 'finished'-flag is the catch-all flag for when the request + // is finished, no matter if loading was successful or failed, + // so any cleanup-work should happen here... + ... + if (response->failed) { + // 'failed' is true in (addition to 'finished') if something + // went wrong (file doesn't exist, or less bytes could be + // read from the file than expected) + } + } + } + + (4) pump the sokol-fetch message queues, and invoke response callbacks + by calling: + + sfetch_dowork(); + + In an event-driven app this should be called in the event loop. If you + use sokol-app this would be in your frame_cb function. + + (5) finally, call sfetch_shutdown() at the end of the application: + + There's many other loading-scenarios, for instance one doesn't have to + provide a buffer upfront, this can also happen in the response callback. + + Or it's possible to stream huge files into small fixed-size buffer, + complete with pausing and continuing the download. + + It's also possible to improve the 'pipeline throughput' by fetching + multiple files in parallel, but at the same time limit the maximum + number of requests that can be 'in-flight'. + + For how this all works, please read the following documentation sections :) + + + API DOCUMENTATION + ================= + + void sfetch_setup(const sfetch_desc_t* desc) + -------------------------------------------- + First call sfetch_setup(const sfetch_desc_t*) on any thread before calling + any other sokol-fetch functions on the same thread. + + sfetch_setup() takes a pointer to an sfetch_desc_t struct with setup + parameters. Parameters which should use their default values must + be zero-initialized: + + - max_requests (uint32_t): + The maximum number of requests that can be alive at any time, the + default is 128. + + - num_channels (uint32_t): + The number of "IO channels" used to parallelize and prioritize + requests, the default is 1. + + - num_lanes (uint32_t): + The number of "lanes" on a single channel. Each request which is + currently 'inflight' on a channel occupies one lane until the + request is finished. This is used for automatic rate-limiting + (search below for CHANNELS AND LANES for more details).

Search for LATENCY AND THROUGHPUT below for more information on + how to increase throughput. + + NOTE that you can call sfetch_setup() on multiple threads, each thread + will get its own thread-local sokol-fetch instance, which will work + independently from sokol-fetch instances on other threads. + + void sfetch_shutdown(void) + -------------------------- + Call sfetch_shutdown() at the end of the application to stop any + IO threads and free all memory that was allocated in sfetch_setup(). + + sfetch_handle_t sfetch_send(const sfetch_request_t* request) + ------------------------------------------------------------ + Call sfetch_send() to start loading data, the function takes a pointer to an + sfetch_request_t struct with request parameters and returns a + sfetch_handle_t identifying the request for later calls. At least + a path/URL and callback must be provided: + + sfetch_handle_t h = sfetch_send(&(sfetch_request_t){ + .path = "my_file.txt", + .callback = my_response_callback + }); + + sfetch_send() will return an invalid handle if no request can be allocated + from the internal pool because all available request items are 'in-flight'. + + The sfetch_request_t struct contains the following parameters (optional + parameters that are not provided must be zero-initialized): + + - path (const char*, required) + Pointer to an UTF-8 encoded C string describing the filesystem + path or HTTP URL. The string will be copied into an internal data + structure, and passed "as is" (apart from any required + encoding-conversions) to fopen(), CreateFileW() or + the html fetch API call. The maximum length of the string is defined by + the SFETCH_MAX_PATH configuration define, the default is 1024 bytes + including the 0-terminator byte. + + - callback (sfetch_callback_t, required) + Pointer to a response-callback function which is called when the + request needs "user code attention". Search below for REQUEST + STATES AND THE RESPONSE CALLBACK for detailed information about + handling responses in the response callback. + + - channel (uint32_t, optional) + Index of the IO channel where the request should be processed. + Channels are used to parallelize and prioritize requests relative + to each other. Search below for CHANNELS AND LANES for more + information. The default channel is 0. + + - chunk_size (uint32_t, optional) + The chunk_size member is used for streaming data incrementally + in small chunks. After 'chunk_size' bytes have been loaded into + to the streaming buffer, the response callback will be called + with the buffer containing the fetched data for the current chunk. + If chunk_size is 0 (the default), than the whole file will be loaded. + Please search below for CHUNK SIZE AND HTTP COMPRESSION for + important information how streaming works if the web server + is serving compressed data. + + - buffer (sfetch_range_t) + This is a optional pointer/size pair describing a chunk of memory where + data will be loaded into (if no buffer is provided upfront, this + must happen in the response callback). If a buffer is provided, + it must be big enough to either hold the entire file (if chunk_size + is zero), or the *uncompressed* data for one downloaded chunk + (if chunk_size is > 0). + + - user_data (sfetch_range_t) + The user_data ptr/size range struct describe an optional POD blob + (plain-old-data) associated with the request which will be copied(!) + into an internal memory block. The maximum default size of this + memory block is 128 bytes (but can be overridden by defining + SFETCH_MAX_USERDATA_UINT64 before including the notification, note + that this define is in "number of uint64_t", not number of bytes). + The user-data block is 8-byte aligned, and will be copied via + memcpy() (so don't put any C++ "smart members" in there). + + NOTE that request handles are strictly thread-local and only unique + within the thread the handle was created on, and all function calls + involving a request handle must happen on that same thread. + + bool sfetch_handle_valid(sfetch_handle_t request) + ------------------------------------------------- + This checks if the provided request handle is valid, and is associated with + a currently active request. It will return false if: + + - sfetch_send() returned an invalid handle because it couldn't allocate + a new request from the internal request pool (because they're all + in flight) + - the request associated with the handle is no longer alive (because + it either finished successfully, or the request failed for some + reason) + + void sfetch_dowork(void) + ------------------------ + Call sfetch_dowork(void) in regular intervals (for instance once per frame) + on the same thread as sfetch_setup() to "turn the gears". If you are sending + requests but never hear back from them in the response callback function, then + the most likely reason is that you forgot to add the call to sfetch_dowork() + in the per-frame function. + + sfetch_dowork() roughly performs the following work: + + - any new requests that have been sent with sfetch_send() since the + last call to sfetch_dowork() will be dispatched to their IO channels + and assigned a free lane. If all lanes on that channel are occupied + by requests 'in flight', incoming requests must wait until + a lane becomes available + + - for all new requests which have been enqueued on a channel which + don't already have a buffer assigned the response callback will be + called with (response->dispatched == true) so that the response + callback can inspect the dynamically assigned lane and bind a buffer + to the request (search below for CHANNELS AND LANE for more info) + + - a state transition from "user side" to "IO thread side" happens for + each new request that has been dispatched to a channel. + + - requests dispatched to a channel are either forwarded into that + channel's worker thread (on native platforms), or cause an HTTP + request to be sent via an asynchronous fetch() call (on the web + platform) + + - for all requests which have finished their current IO operation a + state transition from "IO thread side" to "user side" happens, + and the response callback is called so that the fetched data + can be processed. + + - requests which are completely finished (either because the entire + file content has been loaded, or they are in the FAILED state) are + freed (this just changes their state in the 'request pool', no actual + memory is freed) + + - requests which are not yet finished are fed back into the + 'incoming' queue of their channel, and the cycle starts again, this + only happens for requests which perform data streaming (not load + the entire file at once). + + void sfetch_cancel(sfetch_handle_t request) + ------------------------------------------- + This cancels a request in the next sfetch_dowork() call and invokes the + response callback with (response.failed == true) and (response.finished + == true) to give user-code a chance to do any cleanup work for the + request. If sfetch_cancel() is called for a request that is no longer + alive, nothing bad will happen (the call will simply do nothing). + + void sfetch_pause(sfetch_handle_t request) + ------------------------------------------ + This pauses an active request in the next sfetch_dowork() call and puts + it into the PAUSED state. For all requests in PAUSED state, the response + callback will be called in each call to sfetch_dowork() to give user-code + a chance to CONTINUE the request (by calling sfetch_continue()). Pausing + a request makes sense for dynamic rate-limiting in streaming scenarios + (like video/audio streaming with a fixed number of streaming buffers. As + soon as all available buffers are filled with download data, downloading + more data must be prevented to allow video/audio playback to catch up and + free up empty buffers for new download data. + + void sfetch_continue(sfetch_handle_t request) + --------------------------------------------- + Continues a paused request, counterpart to the sfetch_pause() function. + + void sfetch_bind_buffer(sfetch_handle_t request, sfetch_range_t buffer) + ---------------------------------------------------------------------------------------- + This "binds" a new buffer (as pointer/size pair) to an active request.

Depending + on the current state of a request, it will be 'owned' either by the + "user-thread" (where the request was sent) or an IO thread. + + You can think of a request as "ping-ponging" between the IO thread and + user thread, any actual IO work is done on the IO thread, while + invocations of the response-callback happen on the user-thread. + + All state transitions and callback invocations happen inside the + sfetch_dowork() function. + + An active request goes through the following states: + + ALLOCATED (user-thread) + + The request has been allocated in sfetch_send() and is + waiting to be dispatched into its IO channel. When this + happens, the request will transition into the DISPATCHED state. + + DISPATCHED (IO thread) + + The request has been dispatched into its IO channel, and a + lane has been assigned to the request. + + If a buffer was provided in sfetch_send() the request will + immediately transition into the FETCHING state and start loading + data into the buffer. + + If no buffer was provided in sfetch_send(), the response + callback will be called with (response->dispatched == true), + so that the response callback can bind a buffer to the + request. Binding the buffer in the response callback makes + sense if the buffer isn't dynamically allocated, but instead + a pre-allocated buffer must be selected from the request's + channel and lane. + + Note that it isn't possible to get a file size in the response callback + which would help with allocating a buffer of the right size, this is + because it isn't possible in HTTP to query the file size before the + entire file is downloaded (...when the web server serves files compressed). + + If opening the file failed, the request will transition into + the FAILED state with the error code SFETCH_ERROR_FILE_NOT_FOUND. + + FETCHING (IO thread) + + While a request is in the FETCHING state, data will be loaded into + the user-provided buffer. + + If no buffer was provided, the request will go into the FAILED + state with the error code SFETCH_ERROR_NO_BUFFER. + + If a buffer was provided, but it is too small to contain the + fetched data, the request will go into the FAILED state with + error code SFETCH_ERROR_BUFFER_TOO_SMALL. + + If less data can be read from the file than expected, the request + will go into the FAILED state with error code SFETCH_ERROR_UNEXPECTED_EOF. + + If loading data into the provided buffer works as expected, the + request will go into the FETCHED state. + + FETCHED (user thread) + + The request goes into the FETCHED state either when the entire file + has been loaded into the provided buffer (when request.chunk_size == 0), + or a chunk has been loaded (and optionally decompressed) into the + buffer (when request.chunk_size > 0). + + The response callback will be called so that the user-code can + process the loaded data using the following sfetch_response_t struct members: + + - data.ptr: pointer to the start of fetched data + - data.size: the number of bytes in the provided buffer + - data_offset: the byte offset of the loaded data chunk in the + overall file (this is only set to a non-zero value in a streaming + scenario) + + Once all file data has been loaded, the 'finished' flag will be set + in the response callback's sfetch_response_t argument. + + After the user callback returns, and all file data has been loaded + (response.finished flag is set) the request has reached its end-of-life + and will be recycled. + + Otherwise, if there's still data to load (because streaming was + requested by providing a non-zero request.chunk_size), the request + will switch back to the FETCHING state to load the next chunk of data. + + Note that it is ok to associate a different buffer or buffer-size + with the request by calling sfetch_bind_buffer() in the response-callback. + + To check in the response callback for the FETCHED state, and + independently whether the request is finished: + + void response_callback(const sfetch_response_t* response) { + if (response->fetched) { + // request is in FETCHED state, the loaded data is available + // in .data.ptr, and the number of bytes that have been + // loaded in .data.size: + const void* data = response->data.ptr; + size_t num_bytes = response->data.size; + } + if (response->finished) { + // the finished flag is set either when all data + // has been loaded, the request has been cancelled, + // or the file operation has failed, this is where + // any required per-request cleanup work should happen + } + } + + + FAILED (user thread) + + A request will transition into the FAILED state in the following situations: + + - if the file doesn't exist or couldn't be opened for other + reasons (SFETCH_ERROR_FILE_NOT_FOUND) + - if no buffer is associated with the request in the FETCHING state + (SFETCH_ERROR_NO_BUFFER) + - if the provided buffer is too small to hold the entire file + (if request.chunk_size == 0), or the (potentially decompressed) + partial data chunk (SFETCH_ERROR_BUFFER_TOO_SMALL) + - if less bytes could be read from the file then expected + (SFETCH_ERROR_UNEXPECTED_EOF) + - if a request has been cancelled via sfetch_cancel() + (SFETCH_ERROR_CANCELLED) + + The response callback will be called once after a request goes into + the FAILED state, with the 'response->finished' and + 'response->failed' flags set to true. + + This gives the user-code a chance to cleanup any resources associated + with the request. + + To check for the failed state in the response callback: + + void response_callback(const sfetch_response_t* response) { + if (response->failed) { + // specifically check for the failed state... + } + // or you can do a catch-all check via the finished-flag: + if (response->finished) { + if (response->failed) { + // if more detailed error handling is needed: + switch (response->error_code) { + ... + } + } + } + } + + PAUSED (user thread) + + A request will transition into the PAUSED state after user-code + calls the function sfetch_pause() on the request's handle. Usually + this happens from within the response-callback in streaming scenarios + when the data streaming needs to wait for a data decoder (like + a video/audio player) to catch up. + + While a request is in PAUSED state, the response-callback will be + called in each sfetch_dowork(), so that the user-code can either + continue the request by calling sfetch_continue(), or cancel + the request by calling sfetch_cancel(). + + When calling sfetch_continue() on a paused request, the request will + transition into the FETCHING state. Otherwise if sfetch_cancel() is + called, the request will switch into the FAILED state. + + To check for the PAUSED state in the response callback: + + void response_callback(const sfetch_response_t* response) { + if (response->paused) { + // we can check here whether the request should + // continue to load data: + if (should_continue(response->handle)) { + sfetch_continue(response->handle); + } + } + } + + + CHUNK SIZE AND HTTP COMPRESSION + =============================== + TL;DR: for streaming scenarios, the provided chunk-size must be smaller + than the provided buffer-size because the web server may decide to + serve the data compressed and the chunk-size must be given in 'compressed + bytes' while the buffer receives 'uncompressed bytes'. It's not possible + in HTTP to query the uncompressed size for a compressed download until + that download has finished. + + With vanilla HTTP, it is not possible to query the actual size of a file + without downloading the entire file first (the Content-Length response + header only provides the compressed size). Furthermore, for HTTP + range-requests, the range is given on the compressed data, not the + uncompressed data. So if the web server decides to serve the data + compressed, the content-length and range-request parameters don't + correspond to the uncompressed data that's arriving in the sokol-fetch + buffers, and there's no way from JS or WASM to either force uncompressed + downloads (e.g. by setting the Accept-Encoding field), or access the + compressed data. + + This has some implications for sokol_fetch.h, most notably that buffers + can't be provided in the exactly right size, because that size can't + be queried from HTTP before the data is actually downloaded. + + When downloading whole files at once, it is basically expected that you + know the maximum files size upfront through other means (for instance + through a separate meta-data-file which contains the file sizes and + other meta-data for each file that needs to be loaded). + + For streaming downloads the situation is a bit more complicated. These + use HTTP range-requests, and those ranges are defined on the (potentially) + compressed data which the JS/WASM side doesn't have access to. However, + the JS/WASM side only ever sees the uncompressed data, and it's not possible + to query the uncompressed size of a range request before that range request + has finished. + + If the provided buffer is too small to contain the uncompressed data, + the request will fail with error code SFETCH_ERROR_BUFFER_TOO_SMALL. + + + CHANNELS AND LANES + ================== + Channels and lanes are (somewhat artificial) concepts to manage + parallelization, prioritization and rate-limiting. + + Channels can be used to parallelize message processing for better 'pipeline + throughput', and to prioritize requests: user-code could reserve one + channel for streaming downloads which need to run in parallel to other + requests, another channel for "regular" downloads and yet another + high-priority channel which would only be used for small files which need + to start loading immediately. + + Each channel comes with its own IO thread and message queues for pumping + messages in and out of the thread. The channel where a request is + processed is selected manually when sending a message: + + sfetch_send(&(sfetch_request_t){ + .path = "my_file.txt", + .callback = my_response_callback, + .channel = 2 + }); + + The number of channels is configured at startup in sfetch_setup() and + cannot be changed afterwards. + + Channels are completely separate from each other, and a request will + never "hop" from one channel to another. + + Each channel consists of a fixed number of "lanes" for automatic rate + limiting: + + When a request is sent to a channel via sfetch_send(), a "free lane" will + be picked and assigned to the request. The request will occupy this lane + for its entire life time (also while it is paused). If all lanes of a + channel are currently occupied, new requests will wait until a + lane becomes unoccupied. + + Since the number of channels and lanes is known upfront, it is guaranteed + that there will never be more than "num_channels * num_lanes" requests + in flight at any one time. + + This guarantee eliminates unexpected load- and memory-spikes when + many requests are sent in very short time, and it allows to pre-allocate + a fixed number of memory buffers which can be reused for the entire + "lifetime" of a sokol-fetch context. + + In the most simple scenario - when a maximum file size is known - buffers + can be statically allocated like this: + + uint8_t buffer[NUM_CHANNELS][NUM_LANES][MAX_FILE_SIZE]; + + Then in the user callback pick a buffer by channel and lane, + and associate it with the request like this: + + void response_callback(const sfetch_response_t* response) { + if (response->dispatched) { + void* ptr = buffer[response->channel][response->lane]; + sfetch_bind_buffer(response->handle, ptr, MAX_FILE_SIZE); + } + ... + } + + + NOTES ON OPTIMIZING PIPELINE LATENCY AND THROUGHPUT + =================================================== + With the default configuration of 1 channel and 1 lane per channel, + sokol_fetch.h will appear to have a shockingly bad loading performance + if several files are loaded. + + This has two reasons: + + (1) all parallelization when loading data has been disabled. A new + request will only be processed, when the last request has finished. + + (2) every invocation of the response-callback adds one frame of latency + to the request, because callbacks will only be called from within + sfetch_dowork() + + sokol-fetch takes a few shortcuts to improve step (2) and reduce + the 'inherent latency' of a request: + + - if a buffer is provided upfront, the response-callback won't be + called in the DISPATCHED state, but start right with the FETCHED state + where data has already been loaded into the buffer + + - there is no separate CLOSED state where the callback is invoked + separately when loading has finished (or the request has failed), + instead the finished and failed flags will be set as part of + the last FETCHED invocation + + This means providing a big-enough buffer to fit the entire file is the + best case, the response callback will only be called once, ideally in + the next frame (or two calls to sfetch_dowork()). + + If no buffer is provided upfront, one frame of latency is added because + the response callback needs to be invoked in the DISPATCHED state so that + the user code can bind a buffer. + + This means the best case for a request without an upfront-provided + buffer is 2 frames (or 3 calls to sfetch_dowork()). + + That's about what can be done to improve the latency for a single request, + but the really important step is to improve overall throughput. If you + need to load thousands of files you don't want that to be completely + serialized. + + The most important action to increase throughput is to increase the + number of lanes per channel. This defines how many requests can be + 'in flight' on a single channel at the same time. The guiding decision + factor for how many lanes you can "afford" is the memory size you want + to set aside for buffers. Each lane needs its own buffer so that + the data loaded for one request doesn't scribble over the data + loaded for another request. + + Here's a simple example of sending 4 requests without upfront buffer + on a channel with 1, 2 and 4 lanes, each line is one frame: + + 1 LANE (8 frames): + Lane 0: + ------------- + REQ 0 DISPATCHED + REQ 0 FETCHED + REQ 1 DISPATCHED + REQ 1 FETCHED + REQ 2 DISPATCHED + REQ 2 FETCHED + REQ 3 DISPATCHED + REQ 3 FETCHED + + Note how the request don't overlap, so they can all use the same buffer. + + 2 LANES (4 frames): + Lane 0: Lane 1: + ------------------------------------ + REQ 0 DISPATCHED REQ 1 DISPATCHED + REQ 0 FETCHED REQ 1 FETCHED + REQ 2 DISPATCHED REQ 3 DISPATCHED + REQ 2 FETCHED REQ 3 FETCHED + + This reduces the overall time to 4 frames, but now you need 2 buffers so + that requests don't scribble over each other. + + 4 LANES (2 frames): + Lane 0: Lane 1: Lane 2: Lane 3: + ---------------------------------------------------------------------------- + REQ 0 DISPATCHED REQ 1 DISPATCHED REQ 2 DISPATCHED REQ 3 DISPATCHED + REQ 0 FETCHED REQ 1 FETCHED REQ 2 FETCHED REQ 3 FETCHED + + Now we're down to the same 'best-case' latency as sending a single + request. + + Apart from the memory requirements for the streaming buffers (which is + under your control), you can be generous with the number of lanes, + they don't add any processing overhead. + + The last option for tweaking latency and throughput is channels. Each + channel works independently from other channels, so while one + channel is busy working through a large number of requests (or one + very long streaming download), you can set aside a high-priority channel + for requests that need to start as soon as possible. + + On platforms with threading support, each channel runs on its own + thread, but this is mainly an implementation detail to work around + the traditional blocking file IO functions, not for performance reasons. + + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + ... + sfetch_setup(&(sfetch_desc_t){ + // ... + .allocator = { + .alloc_fn = my_alloc, + .free_fn = my_free, + .user_data = ..., + } + }); + ... + + If no overrides are provided, malloc and free will be used. + + This only affects memory allocation calls done by sokol_fetch.h + itself though, not any allocations in OS libraries. + + Memory allocation will only happen on the same thread where sfetch_setup() + was called, so you don't need to worry about thread-safety. + + + ERROR REPORTING AND LOGGING + =========================== + To get any logging information at all you need to provide a logging callback in the setup call, + the easiest way is to use sokol_log.h: + + #include "sokol_log.h" + + sfetch_setup(&(sfetch_desc_t){ + // ... + .logger.func = slog_func + }); + + To override logging with your own callback, first write a logging function like this: + + void my_log(const char* tag, // e.g. 'sfetch' + uint32_t log_level, // 0=panic, 1=error, 2=warn, 3=info + uint32_t log_item_id, // SFETCH_LOGITEM_* + const char* message_or_null, // a message string, may be nullptr in release mode + uint32_t line_nr, // line number in sokol_fetch.h + const char* filename_or_null, // source filename, may be nullptr in release mode + void* user_data) + { + ... + } + + ...and then setup sokol-fetch like this: + + sfetch_setup(&(sfetch_desc_t){ + .logger = { + .func = my_log, + .user_data = my_user_data, + } + }); + + The provided logging function must be reentrant (e.g. be callable from + different threads). + + If you don't want to provide your own custom logger it is highly recommended to use + the standard logger in sokol_log.h instead, otherwise you won't see any warnings or + errors. + + + FUTURE PLANS / V2.0 IDEA DUMP + ============================= + - An optional polling API (as alternative to callback API) + - Move buffer-management into the API? The "manual management" + can be quite tricky especially for dynamic allocation scenarios, + API support for buffer management would simplify cases like + preventing that requests scribble over each other's buffers, or + an automatic garbage collection for dynamically allocated buffers, + or automatically falling back to dynamic allocation if static + buffers aren't big enough. + - Pluggable request handlers to load data from other "sources" + (especially HTTP downloads on native platforms via e.g. libcurl + would be useful) + - I'm currently not happy how the user-data block is handled, this + should getting and updating the user-data should be wrapped by + API functions (similar to bind/unbind buffer) + + + LICENSE + ======= + zlib/libpng license + + Copyright (c) 2019 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

For instance + here is an example from the ozz-skin-sapp.c sample shader which samples an + RGBA32F texture with skinning matrices in the vertex shader: + + ```glsl + @image_sample_type joint_tex unfilterable_float + uniform texture2D joint_tex; + @sampler_type smp nonfiltering + uniform sampler smp; + ``` + + This will result in SG_IMAGESAMPLETYPE_UNFILTERABLE_FLOAT and + SG_SAMPLERTYPE_NONFILTERING being written to the code-generated + sg_shader_desc struct. + + + ON VERTEX FORMATS + ================= + Sokol-gfx implements the same strict mapping rules from CPU-side + vertex component formats to GPU-side vertex input data types: + + - float and packed normalized CPU-side formats must be used as + floating point base type in the vertex shader + - packed signed-integer CPU-side formats must be used as signed + integer base type in the vertex shader + - packed unsigned-integer CPU-side formats must be used as unsigned + integer base type in the vertex shader + + These mapping rules are enforced by the sokol-gfx validation layer, + but only when sufficient reflection information is provided in + `sg_shader_desc.attrs[].base_type`. This is the case when sokol-shdc + is used, otherwise the default base_type will be SG_SHADERATTRBASETYPE_UNDEFINED + which causes the sokol-gfx validation check to be skipped (of course you + can also provide the per-attribute base type information manually when + not using sokol-shdc). + + The detailed mapping rules from SG_VERTEXFORMAT_* to GLSL data types + are as follows: + + - FLOAT[*] => float, vec* + - BYTE4N => vec* (scaled to -1.0 .. +1.0) + - UBYTE4N => vec* (scaled to 0.0 .. +1.0) + - SHORT[*]N => vec* (scaled to -1.0 .. +1.0) + - USHORT[*]N => vec* (scaled to 0.0 .. +1.0) + - INT[*] => int, ivec* + - UINT[*] => uint, uvec* + - BYTE4 => int* + - UBYTE4 => uint* + - SHORT[*] => int* + - USHORT[*] => uint* + + NOTE that sokol-gfx only provides vertex formats with sizes of a multiple + of 4 (e.g. BYTE4N but not BYTE2N). This is because vertex components must + be 4-byte aligned anyway. + + + UNIFORM DATA LAYOUT: + ==================== + NOTE: if you use the sokol-shdc shader compiler tool, you don't need to worry + about the following details. + + The data that's passed into the sg_apply_uniforms() function must adhere to + specific layout rules so that the GPU shader finds the uniform block + items at the right offset. + + For the D3D11 and Metal backends, sokol-gfx only cares about the size of uniform + blocks, but not about the internal layout. The data will just be copied into + a uniform/constant buffer in a single operation and it's up you to arrange the + CPU-side layout so that it matches the GPU side layout. This also means that with + the D3D11 and Metal backends you are not limited to a 'cross-platform' subset + of uniform variable types. + + If you ever only use one of the D3D11, Metal *or* WebGPU backend, you can stop reading here. + + For the GL backends, the internal layout of uniform blocks matters though, + and you are limited to a small number of uniform variable types. This is + because sokol-gfx must be able to locate the uniform block members in order + to upload them to the GPU with glUniformXXX() calls. + + To describe the uniform block layout to sokol-gfx, the following information + must be passed to the sg_make_shader() call in the sg_shader_desc struct: + + - a hint about the used packing rule (either SG_UNIFORMLAYOUT_NATIVE or + SG_UNIFORMLAYOUT_STD140) + - a list of the uniform block members types in the correct order they + appear on the CPU side + + For example if the GLSL shader has the following uniform declarations: + + uniform mat4 mvp; + uniform vec2 offset0; + uniform vec2 offset1; + uniform vec2 offset2; + + ...and on the CPU side, there's a similar C struct: + + typedef struct { + float mvp[16]; + float offset0[2]; + float offset1[2]; + float offset2[2]; + } params_t; + + ...the uniform block description in the sg_shader_desc must look like this: + + sg_shader_desc desc = { + .vs.uniform_blocks[0] = { + .size = sizeof(params_t), + .layout = SG_UNIFORMLAYOUT_NATIVE, // this is the default and can be omitted + .uniforms = { + // order must be the same as in 'params_t': + [0] = { .name = "mvp", .type = SG_UNIFORMTYPE_MAT4 }, + [1] = { .name = "offset0", .type = SG_UNIFORMTYPE_VEC2 }, + [2] = { .name = "offset1", .type = SG_UNIFORMTYPE_VEC2 }, + [3] = { .name = "offset2", .type = SG_UNIFORMTYPE_VEC2 }, + } + } + }; + + With this information sokol-gfx can now compute the correct offsets of the data items + within the uniform block struct. + + The SG_UNIFORMLAYOUT_NATIVE packing rule works fine if only the GL backends are used, + but for proper D3D11/Metal/GL a subset of the std140 layout must be used which is + described in the next section: + + + CROSS-BACKEND COMMON UNIFORM DATA LAYOUT + ======================================== + For cross-platform / cross-3D-backend code it is important that the same uniform block + layout on the CPU side can be used for all sokol-gfx backends. To achieve this, + a common subset of the std140 layout must be used: + + - The uniform block layout hint in sg_shader_desc must be explicitly set to + SG_UNIFORMLAYOUT_STD140. + - Only the following GLSL uniform types can be used (with their associated sokol-gfx enums): + - float => SG_UNIFORMTYPE_FLOAT + - vec2 => SG_UNIFORMTYPE_FLOAT2 + - vec3 => SG_UNIFORMTYPE_FLOAT3 + - vec4 => SG_UNIFORMTYPE_FLOAT4 + - int => SG_UNIFORMTYPE_INT + - ivec2 => SG_UNIFORMTYPE_INT2 + - ivec3 => SG_UNIFORMTYPE_INT3 + - ivec4 => SG_UNIFORMTYPE_INT4 + - mat4 => SG_UNIFORMTYPE_MAT4 + - Alignment for those types must be as follows (in bytes): + - float => 4 + - vec2 => 8 + - vec3 => 16 + - vec4 => 16 + - int => 4 + - ivec2 => 8 + - ivec3 => 16 + - ivec4 => 16 + - mat4 => 16 + - Arrays are only allowed for the following types: vec4, int4, mat4. + + Note that the HLSL cbuffer layout rules are slightly different from the + std140 layout rules, this means that the cbuffer declarations in HLSL code + must be tweaked so that the layout is compatible with std140. + + The by far easiest way to tackle the common uniform block layout problem is + to use the sokol-shdc shader cross-compiler tool! + + + ON STORAGE BUFFERS + ================== + The two main purpose of storage buffers are: + + - to be populated by compute shaders with dynamically generated data + - for providing random-access data to all shader stages + + Storage buffers can be used to pass large amounts of random access structured + data from the CPU side to the shaders. They are similar to data textures, but are + more convenient to use both on the CPU and shader side since they can be accessed + in shaders as as a 1-dimensional array of struct items. + + Storage buffers are *NOT* supported on the following platform/backend combos: + + - macOS+GL (because storage buffers require GL 4.3, while macOS only goes up to GL 4.1) + - platforms which only support a GLES3.0 context (WebGL2 and iOS) + + To use storage buffers, the following steps are required: + + - write a shader which uses storage buffers (vertex- and fragment-shaders + can only read from storage buffers, while compute-shaders can both read + and write storage buffers) + - create one or more storage buffers via sg_make_buffer() with the + buffer type SG_BUFFERTYPE_STORAGEBUFFER + - when creating a shader via sg_make_shader(), populate the sg_shader_desc + struct with binding info (when using sokol-shdc, this step will be taken care + of automatically) + - which storage buffer bind slots on the vertex-, fragment- or compute-stage + are occupied + - whether the storage buffer on that bind slot is readonly (readonly + bindings are required for vertex- and fragment-shaders, and in compute + shaders the readonly flag is used to control hazard tracking in some + 3D backends) + + - when calling sg_apply_bindings(), apply the matching bind slots with the previously + created storage buffers + - ...and that's it. + + For more details, see the following backend-agnostic sokol samples: + + - simple vertex pulling from a storage buffer: + - C code: https://github.com/floooh/sokol-samples/blob/master/sapp/vertexpull-sapp.c + - shader: https://github.com/floooh/sokol-samples/blob/master/sapp/vertexpull-sapp.glsl + - instanced rendering via storage buffers (vertex- and instance-pulling): + - C code: https://github.com/floooh/sokol-samples/blob/master/sapp/instancing-pull-sapp.c + - shader: https://github.com/floooh/sokol-samples/blob/master/sapp/instancing-pull-sapp.glsl + - storage buffers both on the vertex- and fragment-stage: + - C code: https://github.com/floooh/sokol-samples/blob/master/sapp/sbuftex-sapp.c + - shader: https://github.com/floooh/sokol-samples/blob/master/sapp/sbuftex-sapp.glsl + - the Ozz animation sample rewritten to pull all rendering data from storage buffers: + - C code: https://github.com/floooh/sokol-samples/blob/master/sapp/ozz-storagebuffer-sapp.cc + - shader: https://github.com/floooh/sokol-samples/blob/master/sapp/ozz-storagebuffer-sapp.glsl + - the instancing sample modified to use compute shaders: + - C code: https://github.com/floooh/sokol-samples/blob/master/sapp/instancing-compute-sapp.c + - shader: https://github.com/floooh/sokol-samples/blob/master/sapp/instancing-compute-sapp.glsl + - the Compute Boids sample ported to sokol-gfx: + - C code: https://github.com/floooh/sokol-samples/blob/master/sapp/computeboids-sapp.c + - shader: https://github.com/floooh/sokol-samples/blob/master/sapp/computeboids-sapp.glsl + + ...also see the following backend-specific vertex pulling samples (those also don't use sokol-shdc): + + - D3D11: https://github.com/floooh/sokol-samples/blob/master/d3d11/vertexpulling-d3d11.c + - desktop GL: https://github.com/floooh/sokol-samples/blob/master/glfw/vertexpulling-glfw.c + - Metal: https://github.com/floooh/sokol-samples/blob/master/metal/vertexpulling-metal.c + - WebGPU: https://github.com/floooh/sokol-samples/blob/master/wgpu/vertexpulling-wgpu.c + + ...and the backend specific compute shader samples: + + - D3D11: https://github.com/floooh/sokol-samples/blob/master/d3d11/instancing-compute-d3d11.c + - desktop GL: https://github.com/floooh/sokol-samples/blob/master/glfw/instancing-compute-glfw.c + - Metal: https://github.com/floooh/sokol-samples/blob/master/metal/instancing-compute-metal.c + - WebGPU: https://github.com/floooh/sokol-samples/blob/master/wgpu/instancing-compute-wgpu.c + + Storage buffer shader authoring caveats when using sokol-shdc: + + - declare a read-only storage buffer interface block with `layout(binding=N) readonly buffer [name] { ... }` + (where 'N' is the index in `sg_bindings.storage_buffers[N]`) + - ...or a read/write storage buffer interface block with `layout(binding=N) buffer [name] { ... }` + - declare a struct which describes a single array item in the storage buffer interface block + - only put a single flexible array member into the storage buffer interface block + + E.g. a complete example in 'sokol-shdc GLSL': + + ```glsl + @vs + // declare a struct: + struct sb_vertex { + vec3 pos;

When a public API function is called, and + a trace hook callback has been installed for this function, the + callback will be invoked with the parameters and result of the function. + This is useful for things like debugging- and profiling-tools, or + keeping track of resource creation and destruction. + + To use the trace hook feature: + + --- Define SOKOL_TRACE_HOOKS before including the implementation. + + --- Setup an sg_trace_hooks structure with your callback function + pointers (keep all function pointers you're not interested + in zero-initialized), optionally set the user_data member + in the sg_trace_hooks struct. + + --- Install the trace hooks by calling sg_install_trace_hooks(), + the return value of this function is another sg_trace_hooks + struct which contains the previously set of trace hooks. + You should keep this struct around, and call those previous + functions pointers from your own trace callbacks for proper + chaining. + + As an example of how trace hooks are used, have a look at the + imgui/sokol_gfx_imgui.h header which implements a realtime + debugging UI for sokol_gfx.h on top of Dear ImGui. + + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + ... + sg_setup(&(sg_desc){ + // ... + .allocator = { + .alloc_fn = my_alloc, + .free_fn = my_free, + .user_data = ..., + } + }); + ... + + If no overrides are provided, malloc and free will be used. + + This only affects memory allocation calls done by sokol_gfx.h + itself though, not any allocations in OS libraries. + + + ERROR REPORTING AND LOGGING + =========================== + To get any logging information at all you need to provide a logging callback in the setup call + the easiest way is to use sokol_log.h: + + #include "sokol_log.h" + + sg_setup(&(sg_desc){ .logger.func = slog_func }); + + To override logging with your own callback, first write a logging function like this: + + void my_log(const char* tag, // e.g. 'sg' + uint32_t log_level, // 0=panic, 1=error, 2=warn, 3=info + uint32_t log_item_id, // SG_LOGITEM_* + const char* message_or_null, // a message string, may be nullptr in release mode + uint32_t line_nr, // line number in sokol_gfx.h + const char* filename_or_null, // source filename, may be nullptr in release mode + void* user_data) + { + ... + } + + ...and then setup sokol-gfx like this: + + sg_setup(&(sg_desc){ + .logger = { + .func = my_log, + .user_data = my_user_data, + } + }); + + The provided logging function must be reentrant (e.g. be callable from + different threads). + + If you don't want to provide your own custom logger it is highly recommended to use + the standard logger in sokol_log.h instead, otherwise you won't see any warnings or + errors. + + + COMMIT LISTENERS + ================ + It's possible to hook callback functions into sokol-gfx which are called from + inside sg_commit() in unspecified order. This is mainly useful for libraries + that build on top of sokol_gfx.h to be notified about the end/start of a frame. + + To add a commit listener, call: + + static void my_commit_listener(void* user_data) { + ... + } + + bool success = sg_add_commit_listener((sg_commit_listener){ + .func = my_commit_listener, + .user_data = ..., + }); + + The function returns false if the internal array of commit listeners is full, + or the same commit listener had already been added. + + If the function returns true, my_commit_listener() will be called each frame + from inside sg_commit(). + + By default, 1024 distinct commit listeners can be added, but this number + can be tweaked in the sg_setup() call: + + sg_setup(&(sg_desc){ + .max_commit_listeners = 2048, + }); + + An sg_commit_listener item is equal to another if both the function + pointer and user_data field are equal. + + To remove a commit listener: + + bool success = sg_remove_commit_listener((sg_commit_listener){ + .func = my_commit_listener, + .user_data = ..., + }); + + ...where the .func and .user_data field are equal to a previous + sg_add_commit_listener() call. The function returns true if the commit + listener item was found and removed, and false otherwise. + + + RESOURCE CREATION AND DESTRUCTION IN DETAIL + =========================================== + The 'vanilla' way to create resource objects is with the 'make functions': + + sg_buffer sg_make_buffer(const sg_buffer_desc* desc) + sg_image sg_make_image(const sg_image_desc* desc) + sg_sampler sg_make_sampler(const sg_sampler_desc* desc) + sg_shader sg_make_shader(const sg_shader_desc* desc) + sg_pipeline sg_make_pipeline(const sg_pipeline_desc* desc) + sg_attachments sg_make_attachments(const sg_attachments_desc* desc) + + This will result in one of three cases: + + 1. The returned handle is invalid. This happens when there are no more + free slots in the resource pool for this resource type. An invalid + handle is associated with the INVALID resource state, for instance: + + sg_buffer buf = sg_make_buffer(...) + if (sg_query_buffer_state(buf) == SG_RESOURCESTATE_INVALID) { + // buffer pool is exhausted + } + + 2. The returned handle is valid, but creating the underlying resource + has failed for some reason. This results in a resource object in the + FAILED state. The reason *why* resource creation has failed differ + by resource type. Look for log messages with more details. A failed + resource state can be checked with: + + sg_buffer buf = sg_make_buffer(...) + if (sg_query_buffer_state(buf) == SG_RESOURCESTATE_FAILED) { + // creating the resource has failed + } + + 3. And finally, if everything goes right, the returned resource is + in resource state VALID and ready to use. This can be checked + with: + + sg_buffer buf = sg_make_buffer(...) + if (sg_query_buffer_state(buf) == SG_RESOURCESTATE_VALID) { + // creating the resource has failed + } + + When calling the 'make functions', the created resource goes through a number + of states: + + - INITIAL: the resource slot associated with the new resource is currently + free (technically, there is no resource yet, just an empty pool slot) + - ALLOC: a handle for the new resource has been allocated, this just means + a pool slot has been reserved. + - VALID or FAILED: in VALID state any 3D API backend resource objects have + been successfully created, otherwise if anything went wrong, the resource + will be in FAILED state. + + Sometimes it makes sense to first grab a handle, but initialize the + underlying resource at a later time. For instance when loading data + asynchronously from a slow data source, you may know what buffers and + textures are needed at an early stage of the loading process, but actually + loading the buffer or texture content can only be completed at a later time. + + For such situations, sokol-gfx resource objects can be created in two steps. + You can allocate a handle upfront with one of the 'alloc functions': + + sg_buffer sg_alloc_buffer(void) + sg_image sg_alloc_image(void) + sg_sampler sg_alloc_sampler(void) + sg_shader sg_alloc_shader(void) + sg_pipeline sg_alloc_pipeline(void) + sg_attachments sg_alloc_attachments(void) + + This will return a handle with the underlying resource object in the + ALLOC state: + + sg_image img = sg_alloc_image(); + if (sg_query_image_state(img) == SG_RESOURCESTATE_ALLOC) { + // allocating an image handle has succeeded, otherwise + // the image pool is full + } + + Such an 'incomplete' handle can be used in most sokol-gfx rendering functions + without doing any harm, sokol-gfx will simply skip any rendering operation + that involve resources which are not in VALID state. + + At a later time (for instance once the texture has completed loading + asynchronously), the resource creation can be completed by calling one of + the 'init functions', those functions take an existing resource handle and + 'desc struct': + + void sg_init_buffer(sg_buffer buf, const sg_buffer_desc* desc) + void sg_init_image(sg_image img, const sg_image_desc* desc) + void sg_init_sampler(sg_sampler smp, const sg_sampler_desc* desc) + void sg_init_shader(sg_shader shd, const sg_shader_desc* desc) + void sg_init_pipeline(sg_pipeline pip, const sg_pipeline_desc* desc) + void sg_init_attachments(sg_attachments atts, const sg_attachments_desc* desc) + + The init functions expect a resource in ALLOC state, and after the function + returns, the resource will be either in VALID or FAILED state. Calling + an 'alloc function' followed by the matching 'init function' is fully + equivalent with calling the 'make function' alone. + + Destruction can also happen as a two-step process. The 'uninit functions' + will put a resource object from the VALID or FAILED state back into the + ALLOC state: + + void sg_uninit_buffer(sg_buffer buf) + void sg_uninit_image(sg_image img) + void sg_uninit_sampler(sg_sampler smp) + void sg_uninit_shader(sg_shader shd) + void sg_uninit_pipeline(sg_pipeline pip) + void sg_uninit_attachments(sg_attachments pass) + + Calling the 'uninit functions' with a resource that is not in the VALID or + FAILED state is a no-op. + + To finally free the pool slot for recycling call the 'dealloc functions': + + void sg_dealloc_buffer(sg_buffer buf) + void sg_dealloc_image(sg_image img) + void sg_dealloc_sampler(sg_sampler smp) + void sg_dealloc_shader(sg_shader shd) + void sg_dealloc_pipeline(sg_pipeline pip) + void sg_dealloc_attachments(sg_attachments atts) + + Calling the 'dealloc functions' on a resource that's not in ALLOC state is + a no-op, but will generate a warning log message. + + Calling an 'uninit function' and 'dealloc function' in sequence is equivalent + with calling the associated 'destroy function': + + void sg_destroy_buffer(sg_buffer buf) + void sg_destroy_image(sg_image img) + void sg_destroy_sampler(sg_sampler smp) + void sg_destroy_shader(sg_shader shd) + void sg_destroy_pipeline(sg_pipeline pip) + void sg_destroy_attachments(sg_attachments atts) + + The 'destroy functions' can be called on resources in any state and generally + do the right thing (for instance if the resource is in ALLOC state, the destroy + function will be equivalent to the 'dealloc function' and skip the 'uninit part'). + + And finally to close the circle, the 'fail functions' can be called to manually + put a resource in ALLOC state into the FAILED state: + + sg_fail_buffer(sg_buffer buf) + sg_fail_image(sg_image img) + sg_fail_sampler(sg_sampler smp) + sg_fail_shader(sg_shader shd) + sg_fail_pipeline(sg_pipeline pip) + sg_fail_attachments(sg_attachments atts) + + This is recommended if anything went wrong outside of sokol-gfx during asynchronous + resource setup (for instance a file loading operation failed). In this case, + the 'fail function' should be called instead of the 'init function'. + + Calling a 'fail function' on a resource that's not in ALLOC state is a no-op, + but will generate a warning log message. + + NOTE: that two-step resource creation usually only makes sense for buffers + and images, but not for samplers, shaders, pipelines or attachments. Most notably, trying + to create a pipeline object with a shader that's not in VALID state will + trigger a validation layer error, or if the validation layer is disabled, + result in a pipeline object in FAILED state. Same when trying to create + an attachments object with invalid image objects. + + + WEBGPU CAVEATS + ============== + For a general overview and design notes of the WebGPU backend see: + + https://floooh.github.io/2023/10/16/sokol-webgpu.html + + In general, don't expect an automatic speedup when switching from the WebGL2 + backend to the WebGPU backend. Some WebGPU functions currently actually + have a higher CPU overhead than similar WebGL2 functions, leading to the + paradoxical situation that some WebGPU code may be slower than similar WebGL2 + code. + + - when writing WGSL shader code by hand, a specific bind-slot convention + must be used: + + All uniform block structs must use `@group(0)` and bindings in the + range 0..15 + + @group(0) @binding(0..15) + + All textures, samplers and storage buffers must use `@group(1)` and + bindings must be in the range 0..127: + + @group(1) @binding(0..127) + + Note that the number of texture, sampler and storage buffer bindings + is still limited despite the large bind range: + + - up to 16 textures and sampler across all shader stages + - up to 8 storage buffers across all shader stages + + If you use sokol-shdc to generate WGSL shader code, you don't need to worry + about the above binding conventions since sokol-shdc. + + - The sokol-gfx WebGPU backend uses the sg_desc.uniform_buffer_size item + to allocate a single per-frame uniform buffer which must be big enough + to hold all data written by sg_apply_uniforms() during a single frame, + including a worst-case 256-byte alignment (e.g. each sg_apply_uniform + call will cost at least 256 bytes of uniform buffer size). The default size + is 4 MB, which is enough for 16384 sg_apply_uniform() calls per + frame (assuming the uniform data 'payload' is less than 256 bytes + per call). These rules are the same as for the Metal backend, so if + you are already using the Metal backend you'll be fine. + + - sg_apply_bindings(): the sokol-gfx WebGPU backend implements a bindgroup + cache to prevent excessive creation and destruction of BindGroup objects + when calling sg_apply_bindings(). The number of slots in the bindgroups + cache is defined in sg_desc.wgpu_bindgroups_cache_size when calling + sg_setup. The cache size must be a power-of-2 number, with the default being + 1024. The bindgroups cache behaviour can be observed by calling the new + function sg_query_frame_stats(), where the following struct items are + of interest: + + .wgpu.num_bindgroup_cache_hits + .wgpu.num_bindgroup_cache_misses + .wgpu.num_bindgroup_cache_collisions + .wgpu_num_bindgroup_cache_invalidates + .wgpu.num_bindgroup_cache_vs_hash_key_mismatch + + The value to pay attention to is `.wgpu.num_bindgroup_cache_collisions`, + if this number is consistently higher than a few percent of the + .wgpu.num_set_bindgroup value, it might be a good idea to bump the + bindgroups cache size to the next power-of-2. + + - sg_apply_viewport(): WebGPU currently has a unique restriction that viewport + rectangles must be contained entirely within the framebuffer. As a shitty + workaround sokol_gfx.h will clip incoming viewport rectangles against + the framebuffer, but this will distort the clipspace-to-screenspace mapping. + There's no proper way to handle this inside sokol_gfx.h, this must be fixed + in a future WebGPU update (see: https://github.com/gpuweb/gpuweb/issues/373 + and https://github.com/gpuweb/gpuweb/pull/5025) + + - The sokol shader compiler generally adds `diagnostic(off, derivative_uniformity);` + into the WGSL output. Currently only the Chrome WebGPU implementation seems + to recognize this. + + - Likewise, the following sokol-gfx pixel formats are not supported in WebGPU: + R16, R16SN, RG16, RG16SN, RGBA16, RGBA16SN. + Unlike unsupported vertex formats, unsupported pixel formats can be queried + in cross-backend code via sg_query_pixel_format() though. + + - The Emscripten WebGPU shim currently doesn't support the Closure minification + post-link-step (e.g. currently the emcc argument '--closure 1' or '--closure 2' + will generate broken Javascript code. + + - sokol-gfx requires the WebGPU device feature `depth32float-stencil8` to be enabled + (this should be widely supported) + + - sokol-gfx expects that the WebGPU device feature `float32-filterable` to *not* be + enabled (since this would exclude all iOS devices) + + + LICENSE + ======= + zlib/libpng license + + Copyright (c) 2018 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.

This + allows to mix/interleave sokol-gl rendering with other render operations. + + Layered rendering is controlled through two functions: + + sgl_layer(int layer_id) + sgl_draw_layer(int layer_id) + + (and the context-variant sgl_draw_layer(): sgl_context_draw_layer() + + The sgl_layer() function sets the 'current layer', any sokol-gl calls + which internally record draw commands will also store the current layer + in the draw command, and later in a sokol-gfx render pass, a call + to sgl_draw_layer() will only render the draw commands that have + a matching layer. + + The default layer is '0', this is active after sokol-gl setup, and + is also restored at the start of a new frame (but *not* by calling + sgl_defaults()). + + NOTE that calling sgl_draw() is equivalent with sgl_draw_layer(0) + (in general you should either use either use sgl_draw() or + sgl_draw_layer() in an application, but not both). + + WORKING WITH CONTEXTS: + ====================== + If you want to render to more than one sokol-gfx render pass you need to + work with additional sokol-gl context objects (one context object for + each offscreen rendering pass, in addition to the implicitly created + 'default context'. + + All sokol-gl state is tracked per context, and there is always a "current + context" (with the notable exception that the currently set context is + destroyed, more on that later). + + Using multiple contexts can also be useful if you only render in + a single pass, but want to maintain multiple independent "state buckets". + + To create new context object, call: + + sgl_context ctx = sgl_make_context(&(sgl_context_desc){ + .max_vertices = ..., // default: 64k + .max_commands = ..., // default: 16k + .color_format = ..., + .depth_format = ..., + .sample_count = ..., + }); + + The color_format, depth_format and sample_count items must be compatible + with the render pass the sgl_draw() or sgL_context_draw() function + will be called in. + + Creating a context does *not* make the context current. To do this, call: + + sgl_set_context(ctx); + + The currently active context will implicitly be used by most sokol-gl functions + which don't take an explicit context handle as argument. + + To switch back to the default context, pass the global constant SGL_DEFAULT_CONTEXT: + + sgl_set_context(SGL_DEFAULT_CONTEXT); + + ...or alternatively use the function sgl_default_context() instead of the + global constant: + + sgl_set_context(sgl_default_context()); + + To get the currently active context, call: + + sgl_context cur_ctx = sgl_get_context(); + + The following functions exist in two variants, one which use the currently + active context (set with sgl_set_context()), and another version which + takes an explicit context handle instead: + + sgl_make_pipeline() vs sgl_context_make_pipeline() + sgl_error() vs sgl_context_error(); + sgl_draw() vs sgl_context_draw(); + + Except for using the currently active context versus a provided context + handle, the two variants are exactlyidentical, e.g. the following + code sequences do the same thing: + + sgl_set_context(ctx); + sgl_pipeline pip = sgl_make_pipeline(...); + sgl_error_t err = sgl_error(); + sgl_draw(); + + vs + + sgl_pipeline pip = sgl_context_make_pipeline(ctx, ...); + sgl_error_t err = sgl_context_error(ctx); + sgl_context_draw(ctx); + + Destroying the currently active context is a 'soft error'. All following + calls which require a currently active context will silently fail, + and sgl_error() will return SGL_ERROR_NO_CONTEXT. + + UNDER THE HOOD: + =============== + sokol_gl.h works by recording vertex data and rendering commands into + memory buffers, and then drawing the recorded commands via sokol_gfx.h + + The only functions which call into sokol_gfx.h are: + - sgl_setup() + - sgl_shutdown() + - sgl_draw() (and variants) + + sgl_setup() must be called after initializing sokol-gfx. + sgl_shutdown() must be called before shutting down sokol-gfx. + sgl_draw() must be called once per frame inside a sokol-gfx render pass. + + All other sokol-gl function can be called anywhere in a frame, since + they just record data into memory buffers owned by sokol-gl. + + What happens in: + + sgl_setup(): + Unique resources shared by all contexts are created: + - a shader object (using embedded shader source or byte code) + - an 8x8 white default texture + The default context is created, which involves: + - 3 memory buffers are created, one for vertex data, + one for uniform data, and one for commands + - a dynamic vertex buffer is created + - the default sgl_pipeline object is created, which involves + creating 5 sg_pipeline objects + + One vertex is 24 bytes: + - float3 position + - float2 texture coords + - uint32_t color + + One uniform block is 128 bytes: + - mat4 model-view-projection matrix + - mat4 texture matrix + + One draw command is ca. 24 bytes for the actual + command code plus command arguments. + + Each sgl_end() consumes one command, and one uniform block + (only when the matrices have changed). + The required size for one sgl_begin/end pair is (at most): + + (152 + 24 * num_verts) bytes + + sgl_shutdown(): + - all sokol-gfx resources (buffer, shader, default-texture and + all pipeline objects) are destroyed + - the 3 memory buffers are freed + + sgl_draw() (and variants) + - copy all recorded vertex data into the dynamic sokol-gfx buffer + via a call to sg_update_buffer() + - for each recorded command: + - if the layer number stored in the command doesn't match + the layer that's to be rendered, skip to the next + command + - if it's a viewport command, call sg_apply_viewport() + - if it's a scissor-rect command, call sg_apply_scissor_rect() + - if it's a draw command: + - depending on what has changed since the last draw command, + call sg_apply_pipeline(), sg_apply_bindings() and + sg_apply_uniforms() + - finally call sg_draw() + + All other functions only modify the internally tracked state, add + data to the vertex, uniform and command buffers, or manipulate + the matrix stack. + + ON DRAW COMMAND MERGING + ======================= + Not every call to sgl_end() will automatically record a new draw command. + If possible, the previous draw command will simply be extended, + resulting in fewer actual draw calls later in sgl_draw(). + + A draw command will be merged with the previous command if "no relevant + state has changed" since the last sgl_end(), meaning: + + - no calls to sgl_viewport() and sgl_scissor_rect() + - the primitive type hasn't changed + - the primitive type isn't a 'strip type' (no line or triangle strip) + - the pipeline state object hasn't changed + - the current layer hasn't changed + - none of the matrices has changed + - none of the texture state has changed + + Merging a draw command simply means that the number of vertices + to render in the previous draw command will be incremented by the + number of vertices in the new draw command. + + MEMORY ALLOCATION OVERRIDE + ========================== + You can override the memory allocation functions at initialization time + like this: + + void* my_alloc(size_t size, void* user_data) { + return malloc(size); + } + + void my_free(void* ptr, void* user_data) { + free(ptr); + } + + ... + sgl_setup(&(sgl_desc_t){ + // ... + .allocator = { + .alloc_fn = my_alloc, + .free_fn = my_free, + .user_data = ...; + } + }); + ... + + If no overrides are provided, malloc and free will be used. + + + ERROR REPORTING AND LOGGING + =========================== + To get any logging information at all you need to provide a logging callback in the setup call, + the easiest way is to use sokol_log.h: + + #include "sokol_log.h" + + sgl_setup(&(sgl_desc_t){ + // ... + .logger.func = slog_func + }); + + To override logging with your own callback, first write a logging function like this: + + void my_log(const char* tag, // e.g. 'sgl' + uint32_t log_level, // 0=panic, 1=error, 2=warn, 3=info + uint32_t log_item_id, // SGL_LOGITEM_* + const char* message_or_null, // a message string, may be nullptr in release mode + uint32_t line_nr, // line number in sokol_gl.h + const char* filename_or_null, // source filename, may be nullptr in release mode + void* user_data) + { + ... + } + + ...and then setup sokol-gl like this: + + sgl_setup(&(sgl_desc_t){ + .logger = { + .func = my_log, + .user_data = my_user_data, + } + }); + + The provided logging function must be reentrant (e.g. be callable from + different threads). + + If you don't want to provide your own custom logger it is highly recommended to use + the standard logger in sokol_log.h instead, otherwise you won't see any warnings or + errors. + + + LICENSE + ======= + zlib/libpng license + + Copyright (c) 2018 Andre Weissflog + + This software is provided 'as-is', without any express or implied warranty. + In no event will the authors be held liable for any damages arising from the + use of this software. + + Permission is granted to anyone to use this software for any purpose, + including commercial applications, and to alter it and redistribute it + freely, subject to the following restrictions: + + 1.
