Concurrency:
- Refactored spinlock out of OS api (deprecated old procs)
- Concurrency utilites:
void spinlock_init(Spinlock *l);
void spinlock_acquire_or_wait(Spinlock* l);
bool spinlock_acquire_or_wait_timeout(Spinlock* l, f64 timeout_seconds);
void spinlock_release(Spinlock* l);
void mutex_init(Mutex *m);
void mutex_destroy(Mutex *m);
void mutex_acquire_or_wait(Mutex *m);
void mutex_release(Mutex *m);
void binary_semaphore_init(Binary_Semaphore *sem, bool initial_state);
void binary_semaphore_destroy(Binary_Semaphore *sem);
void binary_semaphore_wait(Binary_Semaphore *sem);
void binary_semaphore_signal(Binary_Semaphore *sem);
Macro MEMORY_BARRIER
- Concurrency tests
Docs:
- custom_logger.c example to show how one can make a custom logger and have logs displayed in-game
Utility:
- draw_text_and_measure() which is just an overload of draw_text but it also does a measure and returns it
Misc:
- Added u64 thread_id to global context. This is set in main() for main thread and in thread startup when you dispatch a Thread
- Fixed a bug where plain rects would be drawn with the incorrect color
- Fixed a bug where quads from earlier frames would be drawn
- Font loading
- Measuring for formatting & justification
- Utf8 Glyph walking
- Commented example in oogabooga/examples/text_rendering.c
- Small 2D renderer refactor
- Pass 8-bit integers "type" and "sampler_index" to shader
- Sample texture differently depending on "type" (text or regular quad)
- Sample with nearest/linear min/mag depending on sampler_index
- Set min/mag filtering in Draw_Quad
- Images are now created and deleted directly with gfx calls rather than deferring it for gfx_update.
- We can now set image sub data with gfx_set_image_data()
- Images are no longer hard coded to 4 channels
- Utf8 utility:
- utf8_to_utf32(): convert utf8 bytes to a single u32 codepoint
- next_utf8(): Convert first utf8 character in a string to a u32 codepoint and advance the passed string to the next unicode
- Renamed m4_multiply -> m4_mul for consistency
- Refactored os window to be DPI aware (scaled_width vs pixel_width)
- in minimal example, renamed hammer_xform -> rect_xform
