This has popped up because<p>Microui+fenster=Small GUI <a href="https://news.ycombinator.com/item?id=41477446">https://news.ycombinator.com/item?id=41477446</a><p>Was posted in the last day.<p>In that thread I suggested that API compatibility would be the way to go for more esoteric platforms, Since there's already comments here about BSD and Android targets.<p>All you need is<p><pre><code> struct fenster {
const char *title; /* window title */
const int width; /* window width */
const int height; /* window height */
uint32_t *buf; /* window pixels, 24-bit RGB, row by row, pixel by pixel */
int keys[256]; /* keys are mostly ASCII, but arrows are 17..20 */
int mod; /* mod is 4 bits mask, ctrl=1, shift=2, alt=4, meta=8 */
int x; /* mouse X coordinate */
int y; /* mouse Y coordinate */
int mouse; /* 0 = no buttons pressed, 1 = left button pressed */
};
int fenster_open(struct fenster *f)
int fenster_loop(struct fenster *f)
void fenster_close(struct fenster *f)
void fenster_sleep(int ms)
int64_t fenster_time()
fenster_pixel(f, x, y)
uint32_t px = fenster_pixel(f, x, y);
</code></pre>
A bit more for audio, but that's really it's own little API<p>As a mimimal API for doing interactive apps, it's hard to beat. I can see hobbyists who make their own operating systems taking advantage of this to get things working quickly.
