glsl-include  

glsl-include is a rust library for expanding #include directives in GLSL source strings

Quick Start

Cargo.toml:

[dependencies]
glsl-include = "0.3"

main.rs:

extern crate glsl_include;
use glsl_include::Context;

fn main () {
    let main = r"
        #version 410
        #include <platform.glsl>
        #include <common.glsl>
        out vec4 fragColor;
        void main () {
            fragColor = vec4(1.0);
        }";
    let platform = "void platform_fn() {}";
    let common = "uniform float iTime;";
    let expanded_src = Context::new()
        .include("platform.glsl", platform)
        .include("common.glsl",common)
        .expand(main).unwrap();
}

pragma include

The library also expands #pragma include statements with no additonal configuration required.

Benchmarks

cargo bench

The workflow I currently use for benchmarking a changeset:

git checkout master; cargo bench
git checkout feature-branch; cargo bench

For the best results with criterion, install gnuplot (macos: brew install gnuplot)
