highlight-loader - Applies highlight.js to given module

This loader can apply syntax-highlighting via highlight.js in two ways:

1. Given HTML (either straight HTML or the output of something like markdown-loader), it will replace the contents of blocks with syntax-highlighted HTML generated by highlight.js. This is the default behavior.

2. Given a raw file, it will return syntax-highlighted HTML generated by highlight.js. This can be enabled by using the raw parameter.

You probably want to pass the HTML output of this loader through html-loader.

Parameters

$3

If any value is provided, the loader will interpret its input as a raw string to run through highlight.js.

By default, the language is auto-detected. To specify a language, use the lang parameter.

$3

Specify a language for highlight.js. Only works in combination with the raw parameter.

(To specify a language for non-raw input, apply lang-[something] classes to your blocks.)

$3

Execute the input that highlight-loader receives. Useful in cases when chaining another loader which returns a function. One use case is to combine this with the apply-loader.

By default, exec is false and simply treats its input as a string.

Installation

Install with npm:

``bash
npm install highlight-loader --save-dev
`

Make sure highlightjs is included and initialized on your page.

Usage

Add highlight-loader as a webpack loader:

`javascript
module: {
loaders: [
{
test: /\.md$/,
loader: 'html!highlight!markdown',
include: PATHS.markdown
}
]
}
`

Examples

`javascript
// Reading HTML from parsed markdown
var highlightedMarkdown = require('html!highlight!markdown!./README.md');

// Reading a file's raw contents and auto-detecting the language
var highlightedRaw = require('html!highlight?raw=true!./example-script.js');

// Reading a file's raw contents and specifying the language
var highlightedRawCss = require('html!highlight?raw=true&lang=css!./example-stylesheet.css');

// Reading HTML from a template loader
var highlightedRenderedJadeTemplate = require('html!highlight?exec!apply!jade!./index.jade')
`
