grunt-shader-concat

Merges all shader files into one file in a object structure.

Getting Started

This plugin requires Grunt ~0.4.5

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-shader-concat --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-shader-concat');

The "shader_concat" task

Overview

In your project's Gruntfile, add a section named shader_concat to the data object passed into grunt.initConfig().

grunt.initConfig({
  shader_concat: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
});

Options

options.lineEndings

Type: String Default value: \n

A string value that defines the line break in your shader files. This is needed to split the file content in lines.

options.fragmentExtension

Type: String Default value: frag

A string value that is used to determine if the file parsed is a fragment shader.

options.vertexExtension

Type: String Default value: vert

A string value that is used to determine if the file parsed is a vertex shader.

options.groupByShaderType

Type: Boolean Default value: true

A boolean value that determines if the shaders should be subgrouped by shader type.

Directives

In the shader files you can use two directives to control the group and name of the shader in the final file.

shader-concat-group {group name}

Default value: default.

For example: //#shader-concat-group ssao

//#shader-concat-group ssao

precision mediump float;

void main() {
  // etc
}

shader-concat-name {group name}

For example: //#shader-concat-name merger

//#shader-concat-name merger

precision mediump float;

void main() {
  // etc
}

Usage Examples

Default Options

grunt.initConfig({
  shader_concat: {
    options: {},
    files: {
      'tmp/default_options': [
        'test/fixtures/shader1.frag', 
        'test/fixtures/shader1.vert'
      ]
    },
  },
});
