Removed Lines for Files of Any Type Using Regular Expressions That You Define

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-line-remover --save-dev

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


lineremover task

Run this task with the grunt lineremover command.

Removes lines from the files passed in using either an inclusion or exclusion regular expression pattern.


All options assume that you are passing in either a RegExp instance or a string (which will be wrapped in new RegExp()). Also, note that if all lines are removed from a file, the result will not be put into the destination file (as that file would be empty).


Type: RegExp
Default: /\S/g

Does not remove lines that meet the pattern that is passed in. By default, this task uses an inclusion rule that includes non-whitespace characters. This means, that by default the task removes all lines that contain only whitespace.


Type: Boolean
Default: none

Removes lines that meet the pattern that is passed in.

Example config

  lineremover: {
    noOptions: {
      files: {
        'tmp/sampleWithoutWhitespace.html': 'test/fixtures/sampleWithWhitespace.html'
    customExclude: {
      files: {
        'tmp/sampleExclusionRule.html': 'test/fixtures/sampleWithWhitespace.html'
      options: {
        exclusionPattern: /html/g
