fui, standing for framebuffer user interface, is a C library for interacting with the framebuffer in a tty context. It writes directly to the framebuffer device, using a system of layers for drawing. Some stuff that it does:
- Draws pixel values to an arbitrary number of layers, which are then composited together and rendered to the framebuffer.
- Primitive drawing functions for lines, rectangles, and circles.
- Text rendering using a bitmap font.
- Event handling for keyboard and mouse input (using libevdev), with a more generic event system implemented that can be used for other events.
- A cheeky sound system using alsa that can play sine tones and chords for now.
The actual library is in fui, and can be compiled and installed with:
The library can then be used by including -Lfui -l:libfui.a in your compiler flags. The library is statically linked, so you don't need to worry about shared libraries.
There are some (half-baked for now) examples included, in the examples folder. main.c and bodies.c kind of demonstrates most of the components of the library. In the asteroids folder we have a simple asteroids game, which uses the sound system. Also, in tests, there are a few tests implemented using cmocka.
Some stuff running with fui (from main.c).
