sokol_glue.h -- glue helper functions for sokol headers
Project URL: https://github.com/floooh/sokol
Do this:
#define SOKOL_IMPL or
#define SOKOL_GLUE_IMPL
before you include this file in *one* C or C++ file to create the
implementation.
...optionally provide the following macros to override defaults:
SOKOL_ASSERT(c) - your own assert macro (default: assert(c))
SOKOL_GLUE_API_DECL - public function declaration prefix (default: extern)
SOKOL_API_DECL - same as SOKOL_GLUE_API_DECL
SOKOL_API_IMPL - public function implementation prefix (default: -)
If sokol_glue.h is compiled as a DLL, define the following before
including the declaration or implementation:
SOKOL_DLL
On Windows, SOKOL_DLL will define SOKOL_GLUE_API_DECL as __declspec(dllexport)
or __declspec(dllimport) as needed.
OVERVIEW
========
sokol_glue.h provides glue helper functions between sokol_gfx.h and sokol_app.h,
so that sokol_gfx.h doesn't need to depend on sokol_app.h but can be
used with different window system glue libraries.
PROVIDED FUNCTIONS
==================
sg_environment sglue_environment(void)
Returns an sg_environment struct initialized by calling sokol_app.h
functions. Use this in the sg_setup() call like this:
sg_setup(&(sg_desc){
.environment = sglue_enviornment(),
...
});
sg_swapchain sglue_swapchain(void)
Returns an sg_swapchain struct initialized by calling sokol_app.h
functions. Use this in sg_begin_pass() for a 'swapchain pass' like
this:
sg_begin_pass(&(sg_pass){ .swapchain = sglue_swapchain(), ... });

sokol_log.h -- common logging callback for sokol headers
Project URL: https://github.com/floooh/sokol
Example code: https://github.com/floooh/sokol-samples
Do this:
#define SOKOL_IMPL or
#define SOKOL_LOG_IMPL
before you include this file in *one* C or C++ file to create the
implementation.
Optionally provide the following defines when building the implementation:
SOKOL_ASSERT(c) - your own assert macro (default: assert(c))
SOKOL_UNREACHABLE() - a guard macro for unreachable code (default: assert(false))
SOKOL_LOG_API_DECL - public function declaration prefix (default: extern)
SOKOL_API_DECL - same as SOKOL_GFX_API_DECL
SOKOL_API_IMPL - public function implementation prefix (default: -)
Optionally define the following for verbose output:
SOKOL_DEBUG - by default this is defined if _DEBUG is defined
OVERVIEW
========
sokol_log.h provides a default logging callback for other sokol headers.
To use the default log callback, just include sokol_log.h and provide
a function pointer to the 'slog_func' function when setting up the
sokol library:
For instance with sokol_audio.h:
#include "sokol_log.h"
...
saudio_setup(&(saudio_desc){ .logger.func = slog_func });
Logging output goes to stderr and/or a platform specific logging subsystem
(which means that in some scenarios you might see logging messages duplicated):
- Windows: stderr + OutputDebugStringA()
- macOS/iOS/Linux: stderr + syslog()
- Emscripten: console.info()/warn()/error()
- Android: __android_log_write()
On Windows with sokol_app.h also note the runtime config items to make
stdout/stderr output visible on the console for WinMain() applications
via sapp_desc.win32_console_attach or sapp_desc.win32_console_create,
however when running in a debugger on Windows, the logging output should
show up on the debug output UI panel.
In debug mode, a log message might 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 source path and line number is formatted like compiler errors, in some IDEs (like VSCode)
such error messages are clickable.
In release mode, logging is less verbose as to not bloat the executable with string data, but you still get
enough information to identify the type and location of an error:
[sspine][error][id:12][line:3472]
RULES FOR WRITING YOUR OWN LOGGING FUNCTION
===========================================
- 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
