grunt-multi-stage-sourcemap

Remap multi-level sourcemaps using the multi-stage-sourcemap library.

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-multi-stage-sourcemap --save-dev

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

grunt.loadNpmTasks('grunt-multi-stage-sourcemap');

The "multi_stage_sourcemap" task

Overview

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

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

Options

options.map

Type: function

Default value:

function naiveMapping(pathMapFrom, pathMapTo) {

  function getFilename(path) {
    return path.split("/").pop();
  }

  if (getFilename(pathMapFrom) === getFilename(pathMapTo)) {
    return true;
  }
}

A function which decides which maps should be offset to each other. The function recieves the paths to both files and should return true if they match up otherwise it should return false.

By default the function will return true if both files have the same name.

Usage Examples

Default Options

In this example, the default options are used to retrieve the default_options.js.map source map from directory A and remap it using default_options.js.map from directory B.

grunt.initConfig({
  multi_stage_sourcemap: {
    filesFrom: 'test/fixtures/A/default_options.js.map',
    options: {},
    files: [{
      expand: true,
      cwd: 'test/fixtures/B/',
      src: ['default_options.js.map'],
      dest: 'tmp'
    }],
  },
});

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
