grunt-highlight

Run highlight.js over files

Getting Started

This plugin requires Grunt.

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-highlight --save-dev

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

grunt.loadNpmTasks('grunt-highlight');

The "highlight" task

Overview

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

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

Options

options.lang

Type: Boolean Default value: false

If you know the highlight language, use this.

options.useCheerio

Type: Boolean Default value: true

You target files are HTML and you want to parse over them and highlight code blocks. Turn off for raw code input.

options.selector

Type: Boolean Default value: pre code

This is what cheerio will be looking for as code block in your HTML. Only used when useCheerio is true.

Usage Examples

Default Options

grunt.initConfig({
  highlight: {
    task: {
      options: {},
      files: {
        'dest/out.html': ['src/in.html'],
      }
    }
  }
});

Full Code Files

If you want to highlight an entire file then use the following:

grunt.initConfig({
  highlight: {
    task: {
      options: {
        useCheerio: false,
        lang: 'javascript' // treat the file as a javascript file
      },
      files: {
        'dest/highlighted.html': ['src/bunch-o-javascript.js'],
      }
    }
  }
});

grunt.initConfig({
  highlight: {
    scripts: {
      options: {
        useCheerio: false,
        lang: 'javascript'
      },
      files: {
        'javascript.html': ['src/script.js']
      }
