grunt-copy-part-of-file

This grunt tasks will copy a portion of one file and insert it into another file. I use this to keep my angular index.html file in sync with my index-e2e.html file rather than trying to manually copy all the scripts each time the index.html changes.

Getting Started

This plugin requires Grunt ~0.4.1

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-copy-part-of-file --save-dev

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

grunt.loadNpmTasks('grunt-copy-part-of-file');

The "copy_part_of_file" task

Overview

In your project's Gruntfile, add a section named copy-part-of-file to the data object passed into grunt.initConfig().

grunt.initConfig({
  copy_part_of_file: {
      simple_replace_scripts: {
          options: {
              sourceFileStartPattern: '<!-- SIMPLE START -->',
              sourceFileEndPattern: '<!-- SIMPLE END -->',
              destinationFileStartPattern: '<!-- START -->',
              destinationFileEndPattern: '<!-- END -->'
          },
          files: {
              'test/fixtures/simple-destination.html': ['test/fixtures/simple-source.html']
          }
      }
  },
})

Options

options.soureFileStartPattern

Type: String Default value: A STRING OR REGEX

A string or regexp value that is used to match part of the source file and start to copy the content at this line.

options.soureFileEndPattern

Type: String Default value: A STRING OR REGEX

A string or regexp value that is used to match part of the source file and stop copying at this line.

options.destinationFileStartPattern

Type: String Default value: A STRING OR REGEX

A string or regexp value that is used to match part of the destination file and begin to copy the source matched above below this spot.

options.destinationFileEndPattern

Type: String Default value: A STRING OR REGEX

A string or regexp value that is used to match part of the destination file and stop coping the source matched above at this line.

Example Usage

In this example I use the following config and source content to create the destination content

Grunt Config

grunt.initConfig({
  copy_part_of_file: {
        simple_replace_scripts: {
            options: {
                sourceFileStartPattern: '<!-- SIMPLE START -->',
                sourceFileEndPattern: '<!-- SIMPLE END -->',
                destinationFileStartPattern: '<!-- START -->',
                destinationFileEndPattern: '<!-- END -->'
            },
            files: {
                'test/fixtures/simple-destination.html': ['test/fixtures/simple-source.html']
            }
        }
    },
})

Source File ( referenced as test/fixtures/simple-source.html in config above )

<!DOCTYPE html>
<html>
<!-- SIMPLE START -->
<head>
    <title></title>
</head>
<!-- SIMPLE END -->
<body>
 
</body>
</html>

Destination File ( referenced as test/fixtures/simple-destination.html in config above )

 
<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
<!-- START -->
<!-- END -->
 
</body>
</html>
 

Final Destination File After Task Runs ( Not that anyone would do this...but two heads are better than one. )

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
<!-- START -->
<head>
    <title></title>
</head>
<!-- END -->
 
</body>
</html>
