libwinr

This is a library that handles the boilerplate necessary to create a window, get its framebuffer to draw on and handle events. It can also render text properly (which is usually difficult without a big fat library). Currently only Wayland is supported, but X11 and Linux framebuffer backends are planned.

Features:

very small API (<20 functions) and implementation (~2k LOC)
handles text rendering
doesn't take control over your main loop
very few dependencies (libwayland-client, libxkbcommon and that's it)

Font rendering is done by SSFN. Fonts are only supported in SFN format and might have to be converted (automatic conversion is a planned feature).

This is alpha software. There will be some rough edges. Be careful.

Example

// draw must be included before the others
#include <winr/draw.h>
#include <winr/font.h>
#include <winr/win.h>

int
main()
{
    char buf[32];
    int buflen = 0;
    Win *w;
    Font *f;

    w = winopen(Point(800, 600), "winr example");
    f = fontopen("monospace", 16);

    w->listen = Eclosed | Eframe | Ekey;

    Event ev;
    do {
        ev = winevent(w);
        if (ev.kind & Ekey) {
            buflen = winkeytext(ev, buf, sizeof(buf));
        }
        if (ev.kind & (Eframe | Ekey)) {
            drawrect(&w->fb, w->fb.r, 0xffffffff);
            drawtext(&w->fb, f, w->fb.r.min, 0xff000000, "Hello, world!", -1);
            if (buflen > 0)
                drawtext(&w->fb, f, w->fb.r.min, 0xff444444, buf, buflen);
            winflush(w);
        }
    } while (!(ev.kind & Eclosed));

    fontclose(f);
    winclose(w);

    return 0;
}

Compiling

You need the wayland-client and xkbcommon headers to compile.

make

To install:

make install

The PREFIX and DESTDIR variables do what you would expect.
