gulp-prism

Check it out on npm!

About

Pipe code snippets through Prism using gulp to pre-tag code blocks at compile time. This only applies to code blocks formatted properly using both the pre and code tags (i.e. <pre><code>) and that have a specified {lang|language}-{LANG_NAME} class on the code tag. See the usage section for more information.

Install

npm install gulp-prism --save-dev

Usage

gulpfile.js

var gulp = require('gulp');
var highlight = require('gulp-prism');

gulp.task('default', function () {
	gulp.src('src/index.html')
		.pipe(highlight())
		.pipe(gulp.dest('dist'));
});

src/index.html

Input

<pre><code class="language-html">&lt;div&gt;
	This will be highlighted!
&lt;div&gt;</code></pre>

Output

<pre><code class="language-html prism"><span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>div</span><span class="token punctuation">&gt;</span></span>
    This will be highlighted!
<span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>div</span><span class="token punctuation">&gt;</span></span></code></pre>

Notes

• You must specify the snippet language on the <code> tag or else the code block will not be highlighted.

• You must use escaped HTML within the <pre><code> block.

• Code blocks that have been highlighted using Prism will have the prism class added to them. Similarly, code blocks that were not highlighted will have the no-prism class added to them.

Known Issues

• No CSS is included. This is intentional as this library is only intended to pre-wrap code snippets within code blocks using Prism's semantic tags. You are required to define and include your own CSS. An example SCSS file can be found here.
