grunt-retro

Add grunt@0.4 functionality to grunt@0.3 plugins

Getting Started

Install this grunt plugin next to your project's grunt.js gruntfile with: npm install grunt-retro

Then inside your grunt plugin or grunt.js (depending on the scope of your intent), load and bind grunt-retro to grunt:

// Inside of grunt plugin (MUST BE DONE IMMEDIATELY AFTER module.exports) 
module.exports = function (grunt) {
  grunt = require('grunt-retro')(grunt);
 
  // Continue with normal actions 
};

Documentation

grunt-retro takes care of the gotchas between grunt@0.3 and grunt@0.4. Below is a list of what we guarantee to work:

Define this.file to match the 0.3 specification; {src, file}
Fallback this.utils to be an object of grunt utilites
Allow for registerTask to alias multiple tasks via single string

grunt.registerTask('multi-task', 'lint clean test');

Add back grunt.helper and grunt.registerHelper system

Nuances

Plugins will receive the same array or non-array input from this.file.src
- In 0.4, this is normalized to always be an array.
Fallback grunt.file.glob.minimatch

Examples

grunt plugin

module.exports = function (grunt) {
  // Bind retro functionality 
  grunt = require('grunt-retro')(grunt);
 
  // Create and register our task 
  grunt.registerTask('rot13', 'Rotate a file by 13', function () {
    // Grab file locations -- normally, we would expandFiles(src) 
    var file = this.file,
        src = file.src,
        dest = file.dest;
 
    // Rotate content 
    var input = grunt.file.read(src),
        output = grunt.helper('rot13', input);
 
    // Write out content 
    grunt.file.write(dest, output);
  });
 
  // Register a helper for performing rot13 
  grunt.registerHelper('rot13', rot13Fn);
};

grunt.js

module.exports = function (grunt) {
  // Bind retro functionality 
  grunt = require('grunt-retro')(grunt);
 
  // Set up config 
  grunt.initConfig({...});
 
  // Register default task 
  grunt.registerTask('default', 'lint test');
};
