Danger - Status

Works for me, but might wipe your harddisk.

What?

Takes a glsl shader, removes white space, comments, etc, and replaces symbols/identifiers/type names by shorter ones that compress better.

Why?

I got tired of installing mono to get shader-minifier working, and needed something that I could embedd into my tools.

Why rust?

Because. And I want to learn rust.

And it's portable, and fast, and future proof.

Usage

Commandline

``` cargo run --help

cargo run -- --input shader.glsl --output shader_crushed.glsl ```

Use --blacklist "dont,crush,these" or ```glsl

// code

pragma SHADERCRUSHEROFF

// code

pragma SHADERCRUSHERON

// code ``` to keep certain identifiers untouched, e.g. uniforms that you need to resolve externaly. Keywords, built-in functions, and 'main' are automatically blacklisted.

Embedded/Linked

From C/C++

c++ shader_crusher::ShaderCrusher* pShaderCrusher = shader_crusher::shadercrusher_new(); shader_crusher::shadercrusher_set_input( pShaderCrusher, fragmentString.c_str() ); shader_crusher::shadercrusher_crush( pShaderCrusher ); char* pOutput = shader_crusher::shadercrusher_get_ouput( pShaderCrusher ); fragmentString = std::string( pOutput ); shader_crusher::shadercrusher_free_ouput( pShaderCrusher, pOutput ); shader_crusher::shadercrusher_free( pShaderCrusher ); Don't forget do include the cbindgen generated header file, and link against the lib.

Stats

I only used it on my shaders so far, but on average the crushed size is 60%, or 40% if you further compress (e.g. with UPX/Crinkler/kkrunchy).

Soon

(because I want it)

Future

(aka not going to happen anytime soon)
