grunt-text-grab

Extract chunks of text from files using regular expressions and save them to multiple formats.

grunt-text-grab

Grab and extract text chunks from files using regular expressions and save as a single file formated by a user defined template.

This plugin requires Grunt ~0.4.2

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-text-grab --save-dev

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

grunt.loadNpmTasks('grunt-text-grab');

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

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

Type: RegExp Default value: none

A regular expression, as a string, that is used to find bits of text to extract from your files.

Type: Array Default value: none

An array of regular expressions, as strings, to exclude from the final output.

Type: String Default value: none

A string that will be prepended to the output file. Can be empty.

Type: String Default value: none

This is the bit of the template that gets repeated on each match. Must contain the ´%s´ symbol as the placeholder for grabbed chunks.

Type: String Default value: none

A string that will be appended to the output file. Can be empty.

In this example we'll be extracting from style.css all CSS class selectors with the exception of any containing the exception expression and writing them as an HTML table with single selector per row.

grunt.initConfig({
  text_grab: {
    options: {
      pattern: '\\.[a-zA-Z][a-zA-Z0-9-]+',
      templateStart: '<table>\n',
      templateRow: '<tr><td>%s</td></tr>\n',
      templateEnd: '</table>\n',
      exceptions: ['exception'],
    },
    files: {
      'tmp/css-classes.html': ['css/style.css'],
    },
  },
});

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