grunt-dust-compiler v0.1.6

A grunt task for compiling dust templates.

Prerequisites

In order to compile dust templates dustjs-linkedin must be installed globally to use the dustc command:

npm install -g dustjs-linkedin

Getting Started

This plugin requires Grunt ~0.4.0

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-dust-compiler --save-dev

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

grunt.loadNpmTasks('grunt-dust-compiler');

This plugin was designed to work with Grunt 0.4.x. If you're still using grunt v0.3.x it's strongly recommended that you upgrade

Dustc task

Run this task with the grunt dustc command.

Task targets, files and options may be specified according to the grunt Configuring tasks guide.

Options

registerFileName

Type: Boolean Default: false

By default dust templates are compiled and registered with its relative path. If registerFileName is set to true, then the compiled template(s) will be registered with only its filename.

Usage Examples

dustc: {
  main: {
    files: [
      // includes files within path
      {expand: true, src: ['path/*'], dest: 'dest/', filter: 'isFile'},

      // includes files within path and its sub-directories
      {expand: true, src: ['path/**'], dest: 'dest/'},

      // makes all src relative to cwd
      {expand: true, cwd: 'path/', src: ['**'], dest: 'dest/'},

      // register dust templates individually with register property
      {src: ['path/file.dust'], dest: 'dest/file.js', register: 'foo'},
    ]
  }
}

This task supports all the file mapping format Grunt supports. Please read Globbing patterns and Building the files object dynamically for additional details.

Here are some additional examples, given the following file tree:

$ tree -I node_modules
.
├── Gruntfile.js
└── src
    ├── a
    └── subdir
        └── b

2 directories, 3 files

Compile a single file tree:

dustc: {
  main: {
    src: 'src/*',
    dest: 'dest/',
  },
},

$ grunt dustc
Running "dustc:main" (dustc) task
Created 1 directories, copied 1 files

Done, without errors.
$ tree -I node_modules
.
├── Gruntfile.js
├── dest
│   └── src
│       ├── a
│       └── subdir
└── src
    ├── a
    └── subdir
        └── b

5 directories, 4 files

Flattening the filepath output:

dustc: {
  main: {
    expand: true,
    cwd: 'src/',
    src: '**',
    dest: 'dest/',
    flatten: true,
    filter: 'isFile',
  },
},

$ grunt dustc
Running "dustc:main" (dustc) task
Copied 2 files

Done, without errors.
$ tree -I node_modules
.
├── Gruntfile.js
├── dest
│   ├── a
│   └── b
└── src
    ├── a
    └── subdir
        └── b

3 directories, 5 files

Troubleshooting

By default, if a file or directory is not found it is quietly ignored. If the file should exist, and non-existence generate an error, then add nonull:true. For instance, this Gruntfile.js entry:

dustc: {
  main: {
    nonull: true,
    src: 'not-there',
    dest: 'create-me',
  },
},

gives this output:

$ grunt dustc
Running "dustc:main" (dustc) task
Warning: Unable to read "not-there" file (Error code: ENOENT). Use --force to continue.

Aborted due to warnings.
