highlightjs-lean

A highlightjs language grammar for the Lean theorem proving language.

Usage

(Usage instructions adapted from the highlightjs-robots-txt README.md.)

Simply include the Highlight.js library in your webpage or Node app, then load this module.

This adds a sorry style on top of the standard highlightjs styles for highlighting sorry and admit. You can set the color of this by adding the following CSS style:

<style>
.hljs-sorry {
  color: red;
}
</style>

Static website or simple usage

Simply load the module after loading Highlight.js. You'll use the minified version found in the dist directory. This module is just a CDN build of the language, so it will register itself as the Javascript is loaded.

<script type="text/javascript" src="/path/to/highlight.min.js"></script>
<script type="text/javascript" charset="UTF-8"
  src="/path/to/highlightjs-lean/dist/lean.min.js"></script>
<script type="text/javascript">
  hljs.highlightAll();
</script>

Using directly from the UNPKG CDN

<script type="text/javascript"
  src="https://unpkg.com/highlightjs-lean/dist/lean.min.js"></script>

• For a minimal HTML page which uses this package from the UNPKG CDN, see test/cdn_test.html (contributed by Ed Ayers).

Important note: If you have pinned a CDN version of highlightjs-lean older than 1.2.0 in your web page, please update as those builds are broken and cannot be fixed. See the explanation in issue #13.

With Node or another build system

If you're using Node / Webpack / Rollup / Browserify, etc, simply require the language module, then register it with Highlight.js.

var hljs = require('highlightjs');
var leanHljs = require('highlightjs-lean');

hljs.registerLanguage("lean", leanHljs);
hljs.highlightAll();
