grunt-indent

A grunt task to change the indentation of files.

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-indent --save-dev

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

grunt.loadNpmTasks('grunt-indent');

The "indent" task

Overview

This task will let you increase or decrease the indentation of lines within files. It simply walks all of the lines in the specified files, adds or removes indents as you specify in the options, and saves the modified files to the location you want.

This is useful for building JavaScript projects where you want the built/concatenated files to have proper indentation.

Options

options.style

Type: String Default value: tab

The type of indentation to add or remove. The options are tab or space.

options.size

Type: Number Default value: 1

The number of options.style characters in an indent. For example, if you use 2 spaces per indent then you would set options.style to space, and this to 2.

options.change

Type: Number Default value: 0

The indentation level change. If this is a positive number it will indent all lines the specified number of times. If this is a negative number it will remove the specified number of indents. If this number is zero then it will merely copy the files without modifying the contents.

Usage Examples

Increase Indentation

In this example the indent task will increase the indent of all .js files in the src directory by one and save the modified files in the dist directory.

grunt.initConfig({
  indent: {
    scripts: {
      src: [
        'src/*.js'
      ],
      dest: 'dist/',
      options: {
        style: 'space',
        size: 2,
        change: 1
      }
    }
  }
});

Decrease Indentation

In this example the indent task will decrease the indent of all .css files in the css directory by one and save the modified files in the dist directory.

grunt.initConfig({
  indent: {
    stylesheets: {
      src: [
        'css/*.css'
      ],
      dest: 'dist/',
      options: {
        style: 'space',
        size: 2,
        change: -1
      }
    }
  }
});
