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.

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(), ... });

|
|

|
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
|
||||||
