GLSL

This package helps to combine GLSL code snippets.

This package is build around functions of type Generator -> Generator. They are all meant to be used in a pipeline (|>) or by composing them (>>).

type Generator

A type that describes a fragment shader

emptyFragmentShader : Generator

This starts a fragment shader pipeline

emptyVertexShader : Generator

Starts a vertex shader

Shaders usually start by defining variables and functions

emptyFragmentShader
    |> defineUniform "vec3" "color"
    |> define glslCodeDefiningAFunction

type alias GLSLType =

String

defineAttribute : GLSLType -> String -> Generator -> Generator

defineUniform : GLSLType -> String -> Generator -> Generator

defineVarying : GLSLType -> String -> Generator -> Generator

define : String -> Generator -> Generator

Then you define the code for main using code snippets and possibly some more variables. Variables used here will be automatically declared in the genrated code.

code
    |> (s "vec4 c = vec4(color * " >> uniform "float" "colorScale" >> ", 1.0);")
    |> s "gl_FragColor = c;"

s : String -> Generator -> Generator

Adds some lines of code to main

attribute : GLSLType -> String -> Generator -> Generator

uniform : GLSLType -> String -> Generator -> Generator

varying : GLSLType -> String -> Generator -> Generator

Then you take a finished Generator and generate code from it:

generateGLSL : Generator -> String

Transform a generator into the finished GLSL code

generateElm : String -> Generator -> String

Transform a generator into the finished elm code
