metalsmith-prism

Syntax highlighting for Metalsmith HTML templates using Prism.js

Requirements

• Node >= 4.x.x
• NPM >= v3.x.x
• Metalsmith >= v2.x.x

Quickstart

• Install metalsmith-prism

  npm install metalsmith-prism --save-dev

• Add language definition to code block

<code class="language-css">p { color: red }</code>

• Add metalsmith-prism plugin to metalsmith

const metalsmith = require('metalsmith');
const metalsmithPrism = require('metalsmith-prism');

metalsmith(__dirname)
  .use(metalsmithPrism())
  .build();

• OPTIONAL To use with Markdown code blocks rendered by metalsmith-markdown

const metalsmith = require('metalsmith');
const markdown = require('metalsmith-markdown');
const metalsmithPrism = require('metalsmith-prism');

metalsmith(__dirname)
  // Custom langPrefix option needed as markdown uses 'lang-' by default:
  .use(markdown( { langPrefix: 'language-' } ))
  .use(metalsmithPrism())
  .build();

Language support

Supports all programming languages that have a corresponding Prism.js component file. Component files are found in the Prism.js components directory.

Options

decode (optional)

• Always decode the html entities when processing language of type markup

Metalsmith(__dirname)
  .use(metalsmithPrism({
    decode: true
  }))

lineNumbers (optional)

• Appends class line-numbers to parent <pre> tag if present

Metalsmith(__dirname)
  .use(metalsmithPrism({
    lineNumbers: true
  }))

preLoad (optional)

• Pre-loads language component(s), such that each language component registers itself in the order given in the input array
• Useful for loading syntax that extends other language components that are not automatically registered by Prism

Metalsmith(__dirname)
  .use(metalsmithPrism({
    preLoad: ["java", "scala"]
  }))
