grunt-regex-replace

Grunt plugin to search and replace text content of files based on regular expression patterns

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

Then add this line to your project's grunt.js gruntfile:

grunt.loadNpmTasks('grunt-regex-replace');

Here is an sample of the definition within the object passed to grunt.initConfig

###Sample Code

"regex-replace": {
    foofoo: { //specify a target with any name
        src: ['foo/bar.js'],
        actions: [
            {
                name: 'bar',
                search: '(^|\\s)console.log',
                replace: '//console.log',
                flags: 'g'
            },{
                name: 'foo',
                search: 'var v = \'[^\']*\';',
                replace: 'var v = \'<%= pkg.release.version_code %>\';',
                flags: ''
            },{
               name: 'foobar',
               search: new RegExp('\\w+'),
               replace: function(){
                    return 'foofoo';
               }
            }
        ]
    }
}

Takes the path to the files relative to the grunt file, it accepts strings as well as an array of file paths. Also supports templates, e.g

  src: 'customisation/*.js',
  src: '**/*.js',
  src: ['foo/bar.js','foo/foo.js'],
  src: ['<%= pkg.id %>/bar.js', 'foo/foo.js']

Accepts an array of objects representing the actions to take place. Each action contains an optional name property, a search property, a replace property and a flags property. Example af an object.

  {
    name: 'foo',
    search: '(^|\\s)console.log',
    replace: '//console.log',
    flags: 'gi'
  }
  
  {
    name: 'bar',
    search: /\\w+/g, //also accepts new RegExp()
    replace: function(){
        return 'foo';
    }
  }

A string value

A regular expression string or object defining the text content to be found.

A string / regular expression pattern or function to replace the text content.

Regular expressions options (ie gmi). if the flags property is not defined it defaults to 'g'. To specify no options, set the flags to empty string (ie flags : '').

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.
