OpenGL in Loli programming language

Building

Copy libloli.so (libloli.dll on windows) to bin directory and execute commands:

mkdir ./build               # make build directory
cmake -S ./ -B ./build      # generate make file to build directory
cd build && make            # compile LoliGL

Then in the build folder you can find GL.so (GL.dll on windows) file.

Using in Loli

Copy GL.so (GL.dll on windows) to pkg directory with your loli sources.
Then import module in code:

import GL

Example: Creating window

import sys
import GL

# define `future` functions
future fn glutKeyboardFunc(Byte, Integer, Integer) { ... }
future fn glutDisplayFunc                          { ... }

# init window
GL.glutInit               ("Test OpenGL application in loli")
GL.glutInitDisplayMode    (GL.GLUT_RGBA | GL.GLUT_SINGLE)
GL.glutInitWindowSize     (200, 200)
GL.glutInitWindowPosition (100, 100)

# create window
GL.glutCreateWindow       (GL.loliGlVersion)

# bind functions
GL.glutDisplayFunc        (glutDisplayFunc)
GL.glutKeyboardFunc       (glutKeyboardFunc)

# main loop
GL.glutMainLoop           ()

fn glutKeyboardFunc(key: Byte, arg1: Integer, arg2: Integer) {
    if (key == 27t): { sys.exit(0) } # on `Esc` press ...
}

fn glutDisplayFunc {
    sayln("on display draw")
}
