## Updates ## Updates
- **20-Feb-2023**: sokol_gfx.h has a new set of functions to get a 'best-effort'
desc struct with the creation parameters of a specific resource object:
```c
sg_buffer_desc sg_query_buffer_desc(sg_buffer buf);
sg_image_desc sg_query_image_desc(sg_image img);
sg_shader_desc sg_query_shader_desc(sg_shader shd);
sg_pipeline_desc sg_query_pipeline_desc(sg_pipeline pip);
sg_pass_desc sg_query_pass_desc(sg_pass pass);
```
The returned structs will *not* be an exact copy of the desc struct that
was used for creation the resource object, instead:
- references to external data (like buffer and image content or
shader sources) will be zeroed
- any attributes that have not been kept around internally after
creation will be zeroed (the ```sg_shader_desc``` struct is most
affected by this, the other structs are fairly complete).
Calling the functions with an invalid or dangling resource handle
will return a completely zeroed struct (thus it may make sense
to first check the resource state via ```sg_query_*_state()```)
Nevertheless, those functions may be useful to get a partially filled out
'creation blueprint' for creating similar resources without the need
to keep and pass around the original desc structs.
>MINOR BREAKING CHANGE: the struct members ```sg_image_info.width``` and
```sg_image_info.height``` have been removed, this information is now
returned by ```sg_query_image_desc()```.
PR: https://github.com/floooh/sokol/pull/796, fixes: https://github.com/floooh/sokol/issues/568
- **17-Feb-2023**: sokol_app.h on macOS now has a proper fix for the problem
that macOS doesn't send key-up events while the Cmd key is held down.
Previously this was handled through a workaround of immediately sending a
key-up event after its key-down event if the Cmd key is currently held down
to prevent a 'stuck key'. The proper fix is now to install an "event monitor"
callback (many thanks to GLFW for finding and implementing the solution).
Unfortunately there's no such solution for the Emscripten code path, which
also don't send a key-up event while Cmd is pressed on macOS (the workaround
there to send a key-up event right on key-down while Cmd is held down to
prevent a stuck key is still in place) For more details, see:
https://github.com/floooh/sokol/issues/794
- **15-Feb-2023**: A fix in the sokol_gfx.h GL backend: due to a bug in the
state cache, the GL backend could only bind a total of
SG_MAX_SHADERSTAGE_IMAGES (= 12) when it actually should be twice that amount
(12 per shader stage). Note however that the total amount of texture bindings
is still internally limited by the GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS
runtime variable (~~currently this is not exposed in sg_limits though~~). Many
thanks to @allcreater for PR https://github.com/floooh/sokol/pull/787.
PS: sg_limits now exposes GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS as
```sg_limits.gl_max_combined_texture_image_units```, and the
value can also be inspected via the debug UI in sokol_gfx_imgui.h.
- **13-Feb-2023**: The way logging works has been completely revamped in
the sokol headers. UWP support has been removed from sokol_audio.h
and sokol_app.h (this also means that the sokol headers no longer contain
any C++ code).
**REQUIRED ACTION**: Since the sokol headers are now completely silent
without a logging callback (explanation below), it is highly recommended
to use the standard logging callback provided by the new header ```sokol_log.h```.
For instance for sokol_gfx.h it looks like this:
```c
#include "sokol_log.h"
//...
sg_setup(&(sg_desc){
//...
.logger.func = slog_func,
});
```
All sokol samples have been updated to use sokol_log.h for logging.
The former logging callback is now a combined
logging- and error-reporting callback, and more information is available
to the logging function:
- a 'tag string' which identifies the sokol headers, this string
is identical with the API prefix (e.g. "sg" for sokol_gfx.h,
"sapp" for sokol_app.h etc...)
- a numeric log level: 0=panic, 1=error, 2=warning, 3=info
- a numeric 'log item id' (think of it as error code, but since
not only errors are reported I called it a log item id)
- a human readable error message
- a source file line number where the log item was reported
- the file path of the sokol header
Log level ```panic``` is special in that it terminates execution inside
the log function. When a sokol header issues a panic log message, it means
that the problem is so big that execution can not continue. By default,
the sokol headers and the standard log function in sokol_log.h call
```abort()``` when a panic log message is issued.
In debug mode (NDEBUG not defined, or SOKOL_DEBUG defined), a log message
(in this case from sokol_spine.h) will look like this:
```
[sspine][error][id:12] /Users/floh/projects/sokol/util/sokol_spine.h:3472:0:
SKELETON_DESC_NO_ATLAS: no atlas object provided in sspine_skeleton_desc.atlas
```
The information can be 'parsed' like this:
- ```[sspine]```: it's a message from sokol_spine.h
- ```[error]```: it's an error
- ```[id:12]```: the numeric log item id (associated with ```SKELETON_DESC_NO_ATLAS``` below)
- source file path and line number in a compiler-specific format - in some IDEs and terminals
this is a clickable link
- the line below is the human readable log item id and message
In release mode (NDEBUG is defined and SOKOL_DEBUG is not defined), log messages
are drastically reduced (the reason is to not bloat the executable with all the extra string data):
```
[sspine][error][id:12][line:3472]
```
...this reduced information still gives all the necessary information to identify the location and type of error.
A custom logging function must adhere to a few rules:
- must be re-entrant because it might be called from different threads
- must treat **all** provided string pointers as optional (can be null)
- don't store the string pointers, copy the string data instead
- must not return for log level panic
A new header ```sokol_log.h``` has been added to provide a standard logging callback implementation
which provides logging output on all platforms to stderr and/or platform specific logging
facilities. ```sokol_log.h``` only uses fputs() and platform specific logging function instead
of fprintf() to preverse some executable size.
**QUESTION**: Why are the sokol headers now silent, unless a logging callback is installed?
This is mainly because a standard logging function which does something meaningful on all
platforms (including Windows and Android) isn't trivial. E.g. printing to stderr is not
enough. It's better to move that stuff into a centralized place in a separate header,
but since the core sokol headers must not (statically) depend on other sokol headers
the only solution that made sense was to provide a standard logging function which must
be 'registered' as a callback.
- **26-Jan-2023**: Work on SRGB support in sokol_gfx.h has started, but
this requires more effort to be really usable. For now, only a new
pixel format has been added: SG_PIXELFORMAT_SRGB8A8 (see https://github.com/floooh/sokol/pull/758,
many thanks to @allcreater). The sokol-gfx GL backend has a temporary
workaround to align behaviour with D3D11 and Metal: automatic SRGB conversion
is enabled for offscreen render passes, but disabled for the default
framebuffer. A proper fix will require separate work on sokol_app.h to
support an SRGB default framebuffer and communicate to sokol-gfx
whether the default framebuffer is SRGB enabled or not.
- **24-Jan-2023**: sokol_gfx.h Metal: A minor inconsistency has been fixed in
the validation layer and an assert for the function ```sg_apply_uniforms()```
which checks the size of the incoming data against the uniform block size.
The validation layer and Metal backend did a ```<=``` test while the D3D11
and GL backends checked for an exact size match. Both the validation layer
and the Metal backend now also check for an exact match. Thanks to @nmr8acme
for noticing the issue and providing a PR! (https://github.com/floooh/sokol/pull/776)
- **23-Jan-2023**: A couple more sokol_audio.h updates:
- an AAudio backend has been added for Android, and made the default. This
means you now need to link with ```aaudio``` instead of ```OpenSLES``` when
using sokol_audio.h on Android. The OpenSLES backend code still exists (for
now), but must be explicitly selected by compiling the sokol_audio.h
implementation with the define ```SAUDIO_ANDROID_SLES``` (e.g. there is
no runtime fallback from AAudio to OpenSLES). AAudio is fully supported
since Android 8.1. Many thanks to @oviano for the initial AAudio PR
(https://github.com/floooh/sokol/pull/484)
- in the WebAudio backend, WebAudio is now properly activated on the first
input action again on Chrome for Android (at some point activating WebAudio
via a ```touchstart``` event stopped working and had to be moved to the
```touchend``` event, see https://github.com/floooh/sokol/issues/701)
- audio backend initialization on iOS and macOS is now a bit more fault-tolerant,
errors during initialization now properly set sokol_audio.h to 'silent mode'
instead of asserting (or in release mode ignoring the error)
- ...and some minor general code cleanup things in sokol_audio.h: backend-specific
functions now generally have a matching prefix (like ```_saudio_alsa_...()```)
for better searchability
- **16-Jan-2023**:
- sokol_audio.h android: https://github.com/floooh/sokol/pull/747 has been merged
which adds a couple more error checks at OpenSLES startup.
- sokol_gfx.h: support for half-float vertex formats has been added via
PR https://github.com/floooh/sokol/pull/745
- sokol_imgui.h: fixes for Dear ImGui 1.89 deprecations (via PR https://github.com/floooh/sokol/pull/761)
- **15-Jan-2023**: two bugfixes in sokol_app.h and sokol_gfx.h:
- sokol_app.h x11: Mouse button events now always return valid mouse
coordinates, also when no mouse movement happened yet
(fixes https://github.com/floooh/sokol/issues/770)
- sokol_gfx.h gl: The GL context is now configured with
GL_UNPACK_ALIGNMENT = 1, this should bring texture creation and updating
behaviour in line with the other backends for tightly packed texture
data that doesn't have a row-pitch with a multiple of 4
(fixes https://github.com/floooh/sokol/issues/767)
- **14-Jan-2023**: sokol_app.h x11: a drag'n'drop related bugfix, the
XdndFinished reply event was sent with the wrong window handle which
confused some apps where the drag operation originated
(see https://github.com/floooh/sokol/pull/765#issuecomment-1382750611)
- **16-Dec-2022**: In the sokol_gfx.h Metal backend: A fix for a Metal
validation layer error which I just discovered yesterday (seems to be new in
macOS 13). When the validation layer is active, and the application window
becomes fully obscured, the validation layer throws an error after a short
time (for details see: https://github.com/floooh/sokol/issues/762).
The reason appears to be that sokol_gfx.h creates a command buffer with
'unretained references' (e.g. the command buffer doesn't manage the
lifetime of resources used by the commands stored in the buffer). This
seems to clash with MTKView's and/or CAMetalLayer's expectations. I fixed
this now by creating a second command buffer with 'retained references',
which only holds the ```presentDrawable``` command. That way, regular
draw commands don't have the refcounting overhead (because they're stored
in an unretained-references cmdbuffer), while the drawable surface is
still properly lifetime managed (because it's used in a separate command
buffer with retained references).
- **15-Dec-2022**: A small but important update in sokol_imgui.h which fixes
touch input handling on mobile devices. Many thanks to github user @Xadiant
for the bug investigation and [PR](https://github.com/floooh/sokol/pull/760).
- **25-Nov-2022**: Some code cleanup around resource creation and destruction in sokol_gfx.h:
- It's now safe to call the destroy, uninit and dealloc functions in any
resource state, in general, the functions will do the right thing without
assertions getting in the way (there are however new log warnings in some
cases though, such as attempting to call an ```sg_dealloc_*()``` function on
a resource object that's not in ALLOC state)
- A related **minor breaking change**: the ```sg_uninit_*()``` functions now return
void instead of bool, this is because ```sg_dealloc_*()``` no longer asserts
when called in the wrong resource state
- Related internal code cleanup in the backend-agnostic resource creation
and cleanup code, better or more consistent function names, etc...
- The validation layer can now be disabled in debug mode with a runtime
flag during setup: ```sg_desc.disable_validation```. This is mainly useful
for test code.
- Creating a pass object with invalid image objects now no longer asserts,
but instead results in a pass object in FAILED state. In debug mode,
the validation layer will still stop at this problem though (it's mostly
an 'undefined API behaviour' fix in release mode).
- Calling ```sg_shutdown()``` with existing resources in ALLOC state will
no longer print a log message about an 'active context mismatch'.
- A new header documentation blurb about the two-step resource creation
and destruction functions (search for RESOURCE CREATION AND DESTRUCTION IN DETAIL)
- **16-Nov-2022**: Render layer support has been added to sokol_debugtext.h,
same general changes as in sokol_gl.h with two new functions:
sdtx_layer(layer_id) to select the layer to record text into, and
sdtx_draw_layer(layer_id) to draw the recorded text in that layer inside a
sokol-gfx render pass. The new sample [debugtext-layers-sapp](https://floooh.github.io/sokol-html5/debugtext-layers-sapp) demonstrates the feature together with
sokol-gl.
- **11-Nov-2022**: sokol_gl.h has 2 new public API functions which enable
layered rendering: sgl_layer(), sgl_draw_layer() (technically it's three
functions: there's also sgl_context_draw_layer(), but that's just a variant of
sgl_draw_layer()). This allows to 'interleave' sokol-gl rendering
with other render operations. The [spine-layers-sapp](https://floooh.github.io/sokol-html5/spine-layers-sapp.html)
sample has been updated to use multiple sokol-gl layers.
- **09-Nov-2022**: sokol_gfx.h now allows to add 'commit listeners', these
are callback functions which are called from inside sg_commit(). This is
mainly useful for libraries which build on top of sokol-gfx to be notified
about the start/end point of a frame, which in turn may simplify the public
API, or the internal implementation, because the library no longer needs to
'guess' when a new frame starts.
For more details, search for 'COMMIT LISTENERS' in the sokol_gfx.h header.
This also results in a minor breaking change in sokol_spine.h: The function
```sspine_new_frame()``` has been removed and replaced with an internal commit
listener.
Likewise, sokol_gl.h now uses a commit listener in the implementation, but
without changing the public API (the feature will be important for an upcoming
sokol-gl feature to support rendering layers, and for this a 'new-frame-function'
would have been needed).
- **05-Nov-2022** A breaking change in sokol_fetch.h, and a minor change in
sokol_app.h which should only break for very few users:
- An ```sfetch_range_t``` ptr/size pair struct has been added to sokol_fetch.h,
and discrete ptr/size pairs have been replaced with sfetch_range_t
items. This affects the structs ```sfetch_request_t``` and ```sfetch_response_t```,
and the function ```sfetch_bind_buffer()```.
- The required changes in ```sfetch_response_t``` might be a bit non-obviois: To
access the fetched data, previous ```.buffer_ptr``` and ```.fetched_size```
was used. The fetched data is now accessible through an ```sfetch_range_t data```
item (```data.ptr``` and ```data.size```). The old ```.fetched_offset``` item
has been renamed to ```.data_offset``` to better conform with the new naming.
- The last two occurrences of discrete ptr/size pairs in sokol_app.h now have also
been replaced with ```sapp_range_t``` items, this only affects the structs
```sapp_html5_fetch_request``` and ```sapp_html5_fetch_response```.
- **03-Nov-2022** The language bindings generation has been updated for Zig 0.10.0,
and clang-14 (there was a minor change in the JSON ast-dump format).
Many thanks to github user @kcbanner for the Zig PR!
- **02-Nov-2022** A new header sokol_spine.h (in the util dir), this is a
renderer and 'handle wrapper' around the spine-c runtime (Spine is a popular 2D
character anim system: http://esotericsoftware.com/). This turned out a much bigger
rabbit-hole than I initially expected, but the effort is justified by being a
experimentation testbed for a couple of things I want to add to other sokol
headers (for instance cleaned up handle pool code, a new logging- and error-reporting
system, render layers which will be useful for sokol_gl.h and sokol_debugtext.h).
- **22-Oct-2022** All sokol headers now allow to override logging with a
callback function (installed in the setup call) instead of defining a SOKOL_LOG
macro. Overriding SOKOL_LOG still works as default fallback, but this is no
longer documented, consider this deprecated. Many thanks to github user
@Manuzor for the PR (see https://github.com/floooh/sokol/pull/721 for details)
- **21-Oct-2022** RGB9E5 pixel format support in sokol_gfx.h and a GLES2 related
bugfix in the sokol_app.h Android backend:
- sokol_gfx.h now supports RGB9E5 textures (3*9 bit RGB + 5 bit shared exponent),
this works in all backends except GLES2 and WebGL1 (use ```sg_query_pixelformat()```
to check for runtime support). Many thanks to github user @allcreater for the PR!
- a bugfix in the sokol_app.h Android backend: when forcing a GLES2 context via
sapp_desc.gl_force_gles2, the Android backend correctly created a GLES2 context,
but then didn't communicate this through the function ```sapp_gles2()``` (which
still returned false in this case). This caused the sokol_gfx.h GL backend to
use the GLES3 code path instead GLES2 (which surprisingly seemed to have worked
fine, at least for the sokol samples which force GLES2).
- **19-Oct-2022** Some fixes in the embedded Javascript code blocks (via EM_JS)
in sokol_app.h, sokol_args.h, sokol_audio.h and sokol_fetch.h:
- the JS code has been 'modernized' (e.g. const and let instead of var,
```() => { ... }``` instead of ```function () { ... }``` for callbacks)
- false positives in the Closure static analysis have been suppressed
via inline hints
- **16-Oct-2022** The Odin bindings generator and the generated bindings have
been simplified (the Odin binding now don't have separate wrapper functions).
Requires the latest Odin release. Also note: On M1 Macs I'm currently seeing
what looks like an ABI problem (in functions which pass color values to the C
side as uint8_t, the colors come out wrong). This also happened with the
previous binding version, so it looks like a regression in Odin. Might be
related to this recent bugfix (which I haven't tested yet):
https://github.com/odin-lang/Odin/issues/2121 Many thanks to @thePHTest for the
PR! (https://github.com/floooh/sokol/pull/719)
- **15-Oct-2022**
- fixes for Emscripten 3.1.24: the sokol headers now use the new
**EM_JS_DEPS()** macro to declare 'indirect dependencies on JS library functions'.
This is a (much more robust) follow-up fix to the Emscripten related fixes from 10-Sep-2022.
The new Emscripten SDK also displays a couple of Javascript "static analyzer" warnings
by the Closure compiler (used in release mode to optimize and minify the generated
JS code). I fixed a couple of those warnings, but some warnings persist (all of them
false positives). Not sure yet if these can be fixed or need to be suppressed, but
that's for another time.
- the webkitAudioContext() fallback in sokol_audio.h's Emscripten backend
has been removed (only AudioContext is supported now), the fallback also
triggered a Closure warning, so it probably never worked as intended anyway.
- I also had to undo an older workaround in sokol_app.h on iOS (https://github.com/floooh/sokol/issues/645)
because this is now triggering a Metal validation layer error (https://github.com/floooh/sokol/issues/726).
The original case is no longer reproducible, so undoing the old workaround seems to
be a quick fix. Eventually I want to get rid of MTKView though, and go down to
CAMetalLayer.
- **08-Oct-2022** sokol_app.h Android backend: the ```sapp_touchpoint``` struct
now has a new item ```sapp_android_tooltype android_tooltype;```. This exposes the
result of the Android NDK function ```AMotionEvent_getToolType()```.
Many thanks to @Wertzui123 for the initial PR (https://github.com/floooh/sokol/pull/717).
- **25-Sep-2022**: sokol_app.h on Linux now optionally supports EGL instead of
GLX for the window system glue code and can create a GLES2 or GLES3 context
instead of a 'desktop GL' context.
To get EGL+GLES2/GLES3, just define SOKOL_GLES2 or SOKOL_GLES3 to compile the
implementation. To get EGL+GL, define SOKOL_GLCORE33 *and* SOKOL_FORCE_EGL.
By default, defining just SOKOL_GLCORE33 uses GLX for the window system glue
(just as before). Many thanks to GH user @billzez for the PR!
- **10-Sep-2022**: sokol_app.h and sokol_args.h has been fixed for Emscripten 3.21, those headers
used the Emscripten Javascript helper function ```ccall()``` which is now part of the
'legacy runtime' and causes linker errors. Instead of ```ccall()``` sokol_app.h and sokol_args.h
now drop down to a lower level set of Emscripten JS helper functions (which hopefully won't
go away anytime soon).
- **05-Aug-2022**: New officially supported and automatically updated language bindings for Odin:
https://github.com/floooh/sokol-odin (also see [gen_odin.py](https://github.com/floooh/sokol/blob/master/bindgen/gen_odin.py))
- **10-Jul-2022**: New features in sokol_app.h and sokol_imgui.h:
- In sokol_app.h it's now possible to set a mouse cursor type from a number of predefined
types via the new function ```sapp_set_mouse_cursor(sapp_mouse_cursor cursor)```. The
available cursor types are compatible with GLFW and Dear ImGui. Supported platforms
are: macOS, linux, win32, uwp and web.
- ```sapp_show_mouse(bool shown)``` now also works on the web platform.
- In sokol_app.h, the poorly defined 'user cursor' feature has been removed (```sapp_desc.user_cursor```
and ```SAPP_EVENTTYPE_UPDATE_CURSOR```). This was a hack to allow changing the mouse cursor and
only worked on Win32 and macOS (with different behaviour). Since setting the cursor type
is now 'properly supported, this hack was removed.
- sokol_imgui.h will now set the cursor type via ```sapp_set_mouse_cursor()```. This can be
disabled with the new ```simgui_desc_t``` item ```disable_set_mouse_cursor```.
- sokol_imgui.h now automatically enables resizing windows from edges (not just the bottom-right corner),
this behaviour can be disabled with the new ```simgui_desc_t``` item ```disable_windows_resize_from_edges```.
- sokol_imgui.h can now optionally write to the alpha channel (useful if you want to render the UI
into a separate render target, which is later composed onto the default framebuffer). The feature
is enabled with the new ```simgui_desc_t``` item ```write_alpha_channel```.
Many thanks to **@tomc1998** for the initial [Linux/X11 mouse cursor type PR](https://github.com/floooh/sokol/pull/678) and
**@luigi-rosso** for the [sokol_imgui.h alpha channel PR](https://github.com/floooh/sokol/pull/687)!
- **03-Jul-2022**: A new sokol_gfx.h function ```bool sg_query_buffer_will_overflow(sg_buffer buf, size_t size)```
which allows to check if a call to ```sg_append_buffer()``` would overflow the buffer. This
is an alternative to the ```sg_query_buffer_overflow()``` function which only reports
the overflow after the fact. Many thanks to @RandyGaul for the PR!
- **29-Jun-2022**: In sokol_app.h with the D3D11 backend, if SOKOL_DEBUG is
defined, and the D3D11 device creation fails, there's now a fallback code
path which tries to create the device again without the D3D11_CREATE_DEVICE_DEBUG
flag. Turns out the D3D11 debug support may suddenly stop working (just happened
to me, indicated by the Win10 "Graphics Tool" feature being silently uninstalled
and failing to install when asked to do so). This fix at least allows sokol_app.h
applications compiled in debug mode to run, even if the D3D11 debug layer doesn't
work.
- **29-May-2022**: The code generation scripts for the
[sokol-nim](https://github.com/floooh/sokol-nim) language bindings have been
revised and updated, many thanks to Gustav Olsson for the PR! (I'm planning to
spend a few more days integrating the bindings generation with Github Actions,
so that it's easier to publish new bindings after updates to the sokol headers).
- **26-May-2022**: The GL backend in sokol_app.h now allows to override the GL
context version via two new items in the ```sapp_desc``` struct:
```sapp_desc.gl_major_version``` and ```sapp_desc.gl_minor_version```. The
default GL context version remains at 3.2. Overriding the GL version might make
sense if you're not using sokol_app.h together with sokol_gfx.h, or otherwise
want to call GL functions directly. Note that this only works for the
'desktop GL' backends (Windows, Linux and macOS), but not for the GLES backends
(Android, iOS, web). Furthermore, on macOS only the GL versions 3.2 and 4.1
are available (plus the special config major=1 minor=0 creates an
NSOpenGLProfileVersionLegacy context). In general: use at your risk :) Many
thanks to Github user @pplux for the PR!
- **15-May-2022**: The way internal memory allocation can be overridden with
your own functions has been changed from global macros to callbacks
provided in the API setup call. For instance in sokol_gfx.h:
```c
void* my_malloc(size_t size, void* userdata) {
(void)userdata; // unused
return malloc(size);
}
void my_free(void* ptr, void* userdata) {
(void)userdata; // unused
free(ptr);
}
//...
sg_setup(&(sg_desc){
//...
.allocator = {
.alloc = my_malloc,
.free = my_free,
.user_data = ...,
}
});
```
sokol_gfx.h will now call ```my_malloc()``` and ```my_free()``` whenever it needs
to allocate or free memory (note however that allocations inside OS
functions or 3rd party libraries are not affected).
If no override functions are provided, the standard library functions ```malloc()``` and ```free()```
will be used, just as before.
This change breaks source compatibility in the following headers:
- **sokol_fontstash.h**: the function signature of ```sfons_create()``` has changed,
this now takes a pointer to a new ```sfons_desc_t``` struct instead of
individual parameters.
- **sokol_gfx_imgui.h** (NOT sokol_imgui.h!): likewise, the function signature of
```sg_imgui_init()``` has changed, this now takes an additional parameter
which is a pointer to a new ```sg_imgui_desc_t``` struct.
All affected headers also have a preprocessor check for the outdated
macros ```SOKOL_MALLOC```, ```SOKOL_CALLOC``` and ```SOKOL_FREE``` and throw
a compilation error if those macros are detected.
(if configuration through macros is still desired this could be added back in
the future, but I figured that the new way is more flexible in most situations).
The header sokol_memtrack.h and the sample [restart-sapp](https://floooh.github.io/sokol-html5/restart-sapp.html) have been updated accordingly.
Also search for ```MEMORY ALLOCATION OVERRIDE``` in the header documentation block
for more details.
- **14-May-2022**: added a helper function ```simgui_map_keycode()``` to
sokol_imgui.h to map sokol_app.h keycodes (```sapp_keycode```,
```SAPP_KEYCODE_*```) to Dear ImGui keycodes (```ImGuiKey```, ```ImGuiKey_*```).
If you're using Dear ImGui function to check for key input, you'll need to
update the code like this:
- Old:
```cpp
ImGui::IsKeyPressed(SAPP_KEYCODE_A);
```
- New:
```cpp
ImGui::IsKeyPressed(simgui_map_keycode(SAPP_KEYCODE_A));
```
This was basically 'fallout' from rewriting the input system in sokol_imgui.h
to the new evented IO system in Dear ImGui.
- **08-Feb-2022**: sokol_imgui.h has been updated for Dear ImGui 1.87:
- sokol_imgui.h's input code has been rewritten to use the new evented IO
system and extended virtual key codes in Dear ImGui
- on non-Emscripten platforms, mouse buttons are no longer "cancelled" when
the mouse leaves the window (since the native desktop platforms
automatically capture the mouse when mouse buttons are pressed, but mouse
capture is not supported in the sokol_app.h Emscripten backend)
- **28-Jan-2022**: some window size behaviour changes in sokol_app.h.
- Asking for a default-sized window (via sapp_desc.width/height = 0) now
behaves a bit differently on desktop platforms. Previously this set the
window size to 640x480, now a default window covers more screen area:
- on Windows CW_USEDEFAULT will be used for the size
- on macOS and Linux, the window size will be 4/5 of the
display size
- no behaviour changes on other platforms
- On Windows and Linux, the window is now centered (in a later update,
more control over the initial window position, and new functions for
positioning and sizing might be provided)
- On Windows, when toggling between windowed and fullscreen, the
window position and size will now be restored (on other platforms
this already happened automatically through the window system)
- On all desktop platforms if an application starts in fullscreen and
then is toggled back to windowed, the window will now be of the
expected size (provided in sapp_desc.width/height)
- **20-Jan-2022**:
- sokol_audio.h: A compatibility fix in the sokol_audio.h WASAPI backend (Windows): On
some configs the IAudioClient::Initialize() call could fail because
of a mismatch between the requested number of channels and speaker config.
See [#614](https://github.com/floooh/sokol/issues/614) for details.
- sokol_app.h D3D11/DXGI: Fix an (uncritical) COM interface leak warning for IDXGIAdapter and
IDXGIFactory at shutdown, introduced with the recent disabling of Alt-Enter.
- **18-Jan-2022**:
- sokol_app.h now has per-monitor DPI support on Windows and macOS: when
the application window is moved to a monitor with different DPI, the values
returned by sapp_dpi_scale(), sapp_width() and sapp_height() will update
accordingly (only if the application requested high-dpi rendering with
```sapp_desc.high_dpi=true```, otherwise the dpi scale value remains
fixed at 1.0f). The application will receive an SAPP_EVENTTYPE_RESIZED event
if the default framebuffer size has changed because of a DPI change.
On Windows this feature requires Win10 version 1703 or later (aka the
'Creators Update'), older Windows version simply behave as before.
Many thank to @tjachmann for the initial PR with the Windows implementation!
- sokol_app.h: DPI scale computation on macOS is now more robust using the
NSScreen.backingScaleFactor value
- sokol_app.h: the new frame timing code in sokol_app.h now detects if the display
refresh rate changes and adjusts itself accordingly (for instance if the
window is moved between displays with different refresh rate)
- sokol_app.h D3D11/DXGI: during window movement and resize, the frame is now
presented with DXGI_PRESENT_DO_NOT_WAIT, this fixes some window system
stuttering issues on Win10 configs with recent NVIDIA drivers.
- sokol_app.h D3D11/DXGI: the application will no longer appear to freeze for
0.5 seconds when the title bar is grabbed with the mouse for movement, but
then not moving the mouse.
- sokol_app.h D3D11/DXGI: DXGI's automatic windowed/fullscreen switching via
Alt-Enter has been disabled, because this switched to 'real' fullscreen mode,
while sokol_app.h's fullscreen mode uses a borderless window. Use the
programmatic fullscreen/window switching via ```sapp_toggle_fullscreen()```
instead.
- **BREAKING CHANGE** in sokol_imgui.h: because the applications' DPI scale
can now change at any time, the DPI scale value is now communicated to
sokol_imgui.h in the ```simgui_new_frame()``` function. This has been
changed to accept a pointer to a new ```simgui_frame_desc_t``` struct.
With C99, change the simgui_new_frame() call as follows (if also using
sokol_app.h):
```c
simgui_new_frame(&(simgui_frame_desc_t){
.width = sapp_width(),
.height = sapp_height(),
.delta_time = sapp_frame_duration(),
.dpi_scale = sapp_dpi_scale()
});
```
On C++ this works:
```c++
simgui_new_frame({ sapp_width(), sapp_height(), sapp_frame_duration(), sapp_dpi_scale() });
```
...or in C++20:
```c++
simgui_new_frame({
.width = sapp_width(),
.height = sapp_height(),
.delta_time = sapp_frame_duration(),
.dpi_scale = sapp_dpi_scale()
});
```
- **KNOWN ISSUE**: the recent change in sokol-audio's WASAPI backend to directly consume
float samples doesn't appear to work on some configs (see [#614](https://github.com/floooh/sokol/issues/614)),
investigation is underway
- **15-Jan-2022**:
- A bugfix in the GL backend for uniform arrays using the 'native' uniform block layout.
The bug was a regression in the recent 'uniform data handling' update. See
[PR #611](https://github.com/floooh/sokol/pull/611) for details, and this [new sample/test](https://github.com/floooh/sokol-samples/blob/master/glfw/uniformarrays-glfw.c).
Many thanks to @nmr8acme for the PR!
- **08-Jan-2022**: some enhancements and cleanup to uniform data handling in sokol_gfx.h
and the sokol-shdc shader compiler:
- *IMPORTANT*: when updating sokol_gfx.h (and you're using the sokol-shdc shader compiler),
don't forget to update the sokol-shdc binaries too!
- The GLSL uniform types int, ivec2, ivec3 and
ivec4 can now be used in shader code, those are exposed to the GL
backends with the new ```sg_uniform_type``` items
```SG_UNIFORM_TYPE_INT[2,3,4]```.
- A new enum ```sg_uniform_layout```, currently with the values SG_UNIFORMLAYOUT_NATIVE
and SG_UNIFORMLAYOUT_STD140. The enum is used in ```sg_shader_uniform_block_desc```
as a 'packing rule hint', so that the GL backend can properly locate the offset
of uniform block members. The default (SG_UNIFORMLAYOUT_NATIVE) keeps the same
behaviour, so existing code shouldn't need to be changed. With the packing
rule SG_UNIFORMLAYOUT_STD140 the uniform block interior is expected to be
layed out according to the OpenGL std140 packing rule.
- Note that the SG_UNIFORMLAYOUT_STD140 only allows a subset of the actual std140
packing rule: arrays are only allowed for the types vec4, int4 and mat4.
This is because the uniform data must still be compatible with
```glUniform()``` calls in the GL backends (which have different
'interior alignment' for arrays).
- The sokol-shdc compiler supports the new uniform types and will annotate the
code-generated sg_shader_desc structs with SG_UNIFORMLAYOUT_STD140,
and there are new errors to make sure that uniform blocks are compatible
with all sokol_gfx.h backends.
- Likewise, sokol_gfx.h has tighter validation for the ```sg_shader_uniform_block```
desc struct, but only when the GL backend is used (in general, the interior
layout of uniform blocks is only relevant for GL backends, on all other backends
sokol_gfx.h just passes the uniform data as an opaque block to the shader)
For more details see:
- [new sections in the sokol_gfx.h documentation](https://github.com/floooh/sokol/blob/ba64add0b67cac16fc86fb6b64d1da5f67e80c0f/sokol_gfx.h#L343-L450)
- [documentation of ```sg_uniform_layout```](https://github.com/floooh/sokol/blob/ba64add0b67cac16fc86fb6b64d1da5f67e80c0f/sokol_gfx.h#L1322-L1355)

PS: and an unrelated change: the frame latency on Win32+D3D11 has been slightly improved
via IDXGIDevice1::SetMaximumFrameLatency()
- **27-Dec-2021**: sokol_app.h frame timing improvements:
- A new function ```double sapp_frame_duration(void)``` which returns the frame
duration in seconds, averaged over the last 256 frames to smooth out
jittering spikes. If available, this uses platform/backend specific
functions of the swapchain API:
- On Windows: DXGI's GetFrameStatistics().SyncQPCTime.
- On Emscripten: the timestamp provided by the RAF callback, this will
still be clamped and jittered on some browsers, but averaged over
a number of frames yields a pretty accurate approximation
of the actual frame duration.
- On Metal, ```MTLDrawable addPresentedHandler + presentedTime```
doesn't appear to function correctly on macOS Monterey and/or M1 Macs, so
instead mach_absolute_time() is called at the start of the MTKView
frame callback.
- In all other situations, the same timing method is used as
in sokol_time.h.
- On macOS and iOS, sokol_app.h now queries the maximum display refresh rate
of the main display and uses this as base to compute the preferred frame
rate (by multiplying with ```sapp_desc.swap_interval```), previously the
preferred frame rate was hardwired to ```60 * swap_interval```. This means
that native macOS and iOS applications may now run at 120Hz instead of
60Hz depending on the device (I realize that this isn't ideal, there
will probably be a different way to hint the preferred interval at
which the frame callback is called, which would also support disabling
vsync and probably also adaptive vsync).
- **19-Dec-2021**: some sokol_audio.h changes:
- on Windows, sokol_audio.h no longer converts audio samples
from float to int16_t, but instead configures WASAPI to directly accept
float samples. Many thanks to github user iOrange for the PR!
- sokol_audio.h has a new public function ```saudio_suspended()``` which
returns true if the audio device/context is currently in suspended mode.
On all backends except WebAudio this always returns false. This allows
to show a visual hint to the user that audio is muted until the first
input event is received.
- **18-Dec-2021**: the sokol_gfx.h ```sg_draw()``` function now uses the currently applied
pipeline object to decide if the GL or D3D11 backend's instanced drawing function
should be called instead of the ```num_instances``` argument. This fixes a
bug on some WebGL configs when instanced rendering is configured
but ```sg_draw()``` is called with an instance count of 1.
- **18-Nov-2021**: sokol_gl.h has a new function to control the point size for
point list rendering: ```void sgl_point_size(float size)```. Note that on D3D11
the point size is currently ignored (since D3D11 doesn't support a point size at
all, the feature will need to be emulated in sokol_gl.h when the D3D11 backend is active).
Also note that points cannot currently be textured, only colored.
