HighlightJS Plugin

A redmine plugin to highlight code blocks much better than coderay! :) 135 languages with autodetection feature, 65 color themes, multi language code highlight (like http+json) Try Your language and choose best theme for You: https://highlightjs.org/static/demo/

Old good coderay:

Example highlihts (monokai_sublime theme) - json, http+json:

It's very easy to use because it works automatically :) finds blocks of code, detects a language (one or more!), highlights it.

Install

Follow the Redmine plugin installation steps at: http://www.redmine.org/wiki/redmine/Plugins

Restart the server (this will ensure that the CSS file and other assets are copied to the right place)
(optional) Configure color theme in Administration -> Plugins -> HighlightJS

Browser Restrictions

Plugin is restricted to work with following browsers (or newer):

  Browser.new('Safari', '2'),
  Browser.new('Firefox', '3'),
  Browser.new('Chrome', '10'),
  Browser.new('Internet Explorer', '9')

If You find out that there are some problems with Your browser then report bug in github, so we can turn it off for selected software. Some people still using old browsers like IE8, when others are up to date. IE8 is unsupported by main lib so there is nothing better than turning on coderay again.

Usage

This plugin will replace existing Coderay highlights, You can specify target language like usual:

<pre><code class="json">
[
      {
        "title": "apples",
        "count": [12000, 20000],
        "description": {"text": "...", "sensitive": false}
      },
      {
        "title": "oranges",
        "count": [17500, null],
        "description": {"text": "...", "sensitive": false}
      }
]
</code></pre>

or use autodetection:

<pre><code>
[
  {
    "title": "apples",
    "count": [12000, 20000],
    "description": {"text": "...", "sensitive": false}
  },
  {
    "title": "oranges",
    "count": [17500, null],
    "description": {"text": "...", "sensitive": false}
  }
]
</code></pre>

Autodetection works great with more than one language on the board, like http with appliction/json body:

<pre><code>
POST /task?id=1 HTTP/1.1
Host: example.org
Content-Type: application/json; charset=utf-8
Content-Length: 19

{"status": "ok", "extended": true}
</code></pre>

To disable highlighting altogether use the nohighlight class:

<pre><code class="nohighlight">...</code></pre>

Plugin additionaly trims white lines from start and end so

<pre><code>{"status": "ok", "extended": true}</code></pre>

is equal to:

<pre><code>
{"status": "ok", "extended": true}
</code></pre>

Build Your own HighlightJS version

If You need subset of supported languages follow instruction on highlightJS site: http://highlightjs.readthedocs.org/en/latest/building-testing.html Just replace redmine_highlightjs/assets/javascript/highlight.pack.min.js with Your build

For Your new language definition follow instructions here: http://highlightjs.readthedocs.org/en/latest/language-guide.html

FAQ:

Line numbers?

No, that probably never happens! http://highlightjs.readthedocs.org/en/latest/line-numbers.html

This plugin removes line numbers from file-view too in order to get one block to highlight.
