Update program.py

Better #include handling using regex

This should fix the issue with includes that contain "-escaped strings. Did not test it though.
This should also work: r"#include\s+[",']?([^",']+)"

Thanks. There might be some unit tests for this. Will take a look over the weekend.

Thanks for looking into it. There might be some other changes needed as well. I still can't get the lygia library to work. I guess the finders somehow get confused with the relative paths.

Right. Looking at this ... https://github.com/patriciogonzalezvivo/lygia#how-to-use-it

#ifdef GL_ES
precision mediump float;
#endif

uniform vec2    u_resolution;
uniform float   u_time;

#include "lygia/space/ratio.glsl"
#include "lygia/math/decimate.glsl"
#include "lygia/draw/circle.glsl"

void main(void) {
    vec3 color = vec3(0.0);
    vec2 st = gl_FragCoord.xy/u_resolution.xy;
    st = ratio(st, u_resolution);
    
    color = vec3(st.x,st.y,abs(sin(u_time)));
    color = decimate(color, 20.);
    color += circle(st, .5, .1);
    
    gl_FragColor = vec4(color, 1.0);
}

I would guess we would need to add some absolute search path to make this work, but I haven't looked at this in ages. It looks very doable to find a solution. I can clone the repo and give it a try soon. Through the creation of this library I was kind of trying to avoid relative paths entirely since they are a source of a lot of issues.

moderngl_window.resources.register_program_dir(absolute_path) is likely to solve it, or just add it to the generic resource path that includes all resource types.

moderngl-window/moderngl_window/resources/__init__.py

Line 28 in f527bc4

def register_program_dir(path: Union[Path, str]) -> None:

I guess the best way to obtain the absolute path is to base it on the location of a module in your project using the __file__ module member.

perfect. thanks for the response. moderngl_window.resources.register_program_dir(absolute_path) worked.
