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. If keeping state in global variables + is not an option, there's an alternative set of callbacks with + an additional user_data pointer argument: + + .user_data (void*) + The user-data argument for the callbacks below + .init_userdata_cb (void (*)(void* user_data)) + .frame_userdata_cb (void (*)(void* user_data)) + .cleanup_userdata_cb (void (*)(void* user_data)) + .event_userdata_cb (void(*)(const sapp_event* event, void* user_data)) + + The function sapp_userdata() can be used to query the user_data + pointer provided in the sapp_desc struct. + + You can also call sapp_query_desc() to get a copy of the + original sapp_desc structure. + + NOTE that there's also an alternative compile mode where sokol_app.h + doesn't "hijack" the main() function. Search below for SOKOL_NO_ENTRY. + + --- Implement the initialization callback function (init_cb), this is called + once after the rendering surface, 3D API and swap chain have been + initialized by sokol_app. All sokol-app functions can be called + from inside the initialization callback, the most useful functions + at this point are: + + int sapp_width(void) + int sapp_height(void) + Returns the current width and height of the default framebuffer in pixels, + this may change from one frame to the next, and it may be different + from the initial size provided in the sapp_desc struct. + + float sapp_widthf(void) + float sapp_heightf(void) + These are alternatives to sapp_width() and sapp_height() which return + the default framebuffer size as float values instead of integer. This + may help to prevent casting back and forth between int and float + in more strongly typed languages than C and C++. + + double sapp_frame_duration(void) + Returns the frame duration in seconds averaged over a number of + frames to smooth out any jittering spikes. + + int sapp_color_format(void) + int sapp_depth_format(void) + The color and depth-stencil pixelformats of the default framebuffer, + as integer values which are compatible with sokol-gfx's + sg_pixel_format enum (so that they can be plugged directly in places + where sg_pixel_format is expected). Possible values are: + + 23 == SG_PIXELFORMAT_RGBA8 + 28 == SG_PIXELFORMAT_BGRA8 + 42 == SG_PIXELFORMAT_DEPTH + 43 == SG_PIXELFORMAT_DEPTH_STENCIL + + int sapp_sample_count(void) + Return the MSAA sample count of the default framebuffer. + + const void* sapp_metal_get_device(void) + const void* sapp_metal_get_current_drawable(void) + const void* sapp_metal_get_depth_stencil_texture(void) + const void* sapp_metal_get_msaa_color_texture(void) + If the Metal backend has been selected, these functions return pointers + to various Metal API objects required for rendering, otherwise + they return a null pointer.

Call the functions sapp_width() and sapp_height() + each frame to get the current size. + + --- Optionally implement the event-callback to handle input events. + sokol-app provides the following type of input events: + - a 'virtual key' was pressed down or released + - a single text character was entered (provided as UTF-32 encoded + UNICODE code point) + - a mouse button was pressed down or released (left, right, middle) + - mouse-wheel or 2D scrolling events + - the mouse was moved + - the mouse has entered or left the application window boundaries + - low-level, portable multi-touch events (began, moved, ended, cancelled) + - the application window was resized, iconified or restored + - the application was suspended or restored (on mobile platforms) + - the user or application code has asked to quit the application + - a string was pasted to the system clipboard + - one or more files have been dropped onto the application window + + To explicitly 'consume' an event and prevent that the event is + forwarded for further handling to the operating system, call + sapp_consume_event() from inside the event handler (NOTE that + this behaviour is currently only implemented for some HTML5 + events, support for other platforms and event types will + be added as needed, please open a GitHub ticket and/or provide + a PR if needed). + + NOTE: Do *not* call any 3D API rendering functions in the event + callback function, since the 3D API context may not be active when the + event callback is called (it may work on some platforms and 3D APIs, + but not others, and the exact behaviour may change between + sokol-app versions). + + --- Implement the cleanup-callback function, this is called once + after the user quits the application (see the section + "APPLICATION QUIT" for detailed information on quitting + behaviour, and how to intercept a pending quit - for instance to show a + "Really Quit?" dialog box). 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(). + + On the web, sapp_desc.fullscreen will have no effect, and the application + will always start in non-fullscreen mode. Call sapp_toggle_fullscreen() + from within or 'near' an input event to switch to fullscreen programatically. + Note that on the web, the fullscreen state may change back to windowed at + any time (either because the browser had rejected switching into fullscreen, + or the user leaves fullscreen via Esc), this means that the result + of sapp_is_fullscreen() may change also without calling sapp_toggle_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.

The pixel data consists of *y scanlines of *x pixels, +// with each pixel consisting of N interleaved 8-bit components; the first +// pixel pointed to is top-left-most in the image.

E.g. if you set desired_channels to 4, you will always +// get RGBA output, but you can check *channels_in_file to see if it's trivially +// opaque because e.g. there were only 3 channels in the source image. +// +// An output image with N components has the following components interleaved +// in this order in each pixel: +// +// N=#comp components +// 1 grey +// 2 grey, alpha +// 3 red, green, blue +// 4 red, green, blue, alpha +// +// If image loading fails for any reason, the return value will be NULL, +// and *x, *y, *channels_in_file will be unchanged. The function +// stbi_failure_reason() can be queried for an extremely brief, end-user +// unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS +// to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly +// more user-friendly ones. +// +// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized. +// +// To query the width, height and component count of an image without having to +// decode the full file, you can use the stbi_info family of functions: +// +// int x,y,n,ok; +// ok = stbi_info(filename, &x, &y, &n); +// // returns ok=1 and sets x, y, n if image is a supported format, +// // 0 otherwise. +// +// Note that stb_image pervasively uses ints in its public API for sizes, +// including sizes of memory buffers. This is now part of the API and thus +// hard to change without causing breakage. As a result, the various image +// loaders all have certain limits on image size; these differ somewhat +// by format but generally boil down to either just under 2GB or just under +// 1GB. When the decoded image would be larger than this, stb_image decoding +// will fail. +// +// Additionally, stb_image will reject image files that have any of their +// dimensions set to a larger value than the configurable STBI_MAX_DIMENSIONS, +// which defaults to 2**24 = 16777216 pixels. Due to the above memory limit, +// the only way to have an image with such dimensions load correctly +// is for it to have a rather extreme aspect ratio. Either way, the +// assumption here is that such larger images are likely to be malformed +// or malicious. If you do need to load an image with individual dimensions +// larger than that, and it still fits in the overall size limit, you can +// #define STBI_MAX_DIMENSIONS on your own to be something larger. +// +// =========================================================================== +// +// UNICODE: +// +// If compiling for Windows and you wish to use Unicode filenames, compile +// with +// #define STBI_WINDOWS_UTF8 +// and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert +// Windows wchar_t filenames to utf8. +// +// =========================================================================== +// +// Philosophy +// +// stb libraries are designed with the following priorities: +// +// 1. easy to use +// 2. easy to maintain +// 3. good performance +// +// Sometimes I let "good performance" creep up in priority over "easy to maintain", +// and for best performance I may provide less-easy-to-use APIs that give higher +// performance, in addition to the easy-to-use ones. Nevertheless, it's important +// to keep in mind that from the standpoint of you, a client of this library, +// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all. +// +// Some secondary priorities arise directly from the first two, some of which +// provide more explicit reasons why performance can't be emphasized. +// +// - Portable ("ease of use") +// - Small source code footprint ("easy to maintain") +// - No dependencies ("ease of use") +// +// =========================================================================== +// +// I/O callbacks +// +// I/O callbacks allow you to read from arbitrary sources, like packaged +// files or some other source. Data read from callbacks are processed +// through a small internal buffer (currently 128 bytes) to try to reduce +// overhead. +// +// The three functions you must define are "read" (reads some bytes of data), +// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end). +// +// =========================================================================== +// +// SIMD support +// +// The JPEG decoder will try to automatically use SIMD kernels on x86 when +// supported by the compiler. For ARM Neon support, you must explicitly +// request it. +// +// (The old do-it-yourself SIMD API is no longer supported in the current +// code.) +// +// On x86, SSE2 will automatically be used when available based on a run-time +// test; if not, the generic C versions are used as a fall-back. On ARM targets, +// the typical path is to have separate builds for NEON and non-NEON devices +// (at least this is true for iOS and Android). Therefore, the NEON support is +// toggled by a build flag: define STBI_NEON to get NEON loops. +// +// If for some reason you do not want to use any of SIMD code, or if +// you have issues compiling it, you can disable it entirely by +// defining STBI_NO_SIMD. +// +// =========================================================================== +// +// HDR image support (disable by defining STBI_NO_HDR) +// +// stb_image supports loading HDR images in general, and currently the Radiance +// .HDR file format specifically. You can still load any file through the existing +// interface; if you attempt to load an HDR file, it will be automatically remapped +// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1; +// both of these constants can be reconfigured through this interface: +// +// stbi_hdr_to_ldr_gamma(2.2f); +// stbi_hdr_to_ldr_scale(1.0f); +// +// (note, do not use _inverse_ constants; stbi_image will invert them +// appropriately). +// +// Additionally, there is a new, parallel interface for loading files as +// (linear) floats to preserve the full dynamic range: +// +// float *data = stbi_loadf(filename, &x, &y, &n, 0); +// +// If you load LDR images through this interface, those images will +// be promoted to floating point values, run through the inverse of +// constants corresponding to the above: +// +// stbi_ldr_to_hdr_scale(1.0f); +// stbi_ldr_to_hdr_gamma(2.2f); +// +// Finally, given a filename (or an open file or memory block--see header +// file for details) containing image data, you can query for the "most +// appropriate" interface to use (that is, whether the image is HDR or +// not), using: +// +// stbi_is_hdr(char *filename); +// +// =========================================================================== +// +// iPhone PNG support: +// +// We optionally support converting iPhone-formatted PNGs (which store +// premultiplied BGRA) back to RGB, even though they're internally encoded +// differently. To enable this conversion, call +// stbi_convert_iphone_png_to_rgb(1). +// +// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per +// pixel to remove any premultiplied alpha *only* if the image file explicitly +// says there's premultiplied data (currently only happens in iPhone images, +// and only if iPhone convert-to-rgb processing is on). +// +// =========================================================================== +// +// ADDITIONAL CONFIGURATION +// +// - You can suppress implementation of any of the decoders to reduce +// your code footprint by #defining one or more of the following +// symbols before creating the implementation. +// +// STBI_NO_JPEG +// STBI_NO_PNG +// STBI_NO_BMP +// STBI_NO_PSD +// STBI_NO_TGA +// STBI_NO_GIF +// STBI_NO_HDR +// STBI_NO_PIC +// STBI_NO_PNM (.ppm and .pgm) +// +// - You can request *only* certain decoders and suppress all other ones +// (this will be more forward-compatible, as addition of new decoders +// doesn't require you to disable them explicitly): +// +// STBI_ONLY_JPEG +// STBI_ONLY_PNG +// STBI_ONLY_BMP +// STBI_ONLY_PSD +// STBI_ONLY_TGA +// STBI_ONLY_GIF +// STBI_ONLY_HDR +// STBI_ONLY_PIC +// STBI_ONLY_PNM (.ppm and .pgm) +// +// - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still +// want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB +// +// - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater +// than that size (in either width or height) without further processing. +// This is to let programs in the wild set an upper bound to prevent +// denial-of-service attacks on untrusted data, as one could generate a +// valid image of gigantic dimensions and force stb_image to allocate a +// huge block of memory and spend disproportionate time decoding it.
