CodeHighlighterPlus

Introduction

I have been using WordPress for a personal blog for many years. Before that, everything was in a PostgreSQL database with journaling software I wrote myself. Before that it was static HTML pages. This is going back to before Y2K. But one thing that I always wanted in the journal was a nice syntax highlighter. CodeHighlighter was nearly perfect.

This is a slight fork of that becauce it also fixes some problems in GeSHI as well. Also, the original CodeHighlighter is evidently not on GitHub. So I've started this project, and it's something that I'll maintain as needed - pulling in GeSHI changes and adding things as I need them.

Installation

At the current time, the only way to install the plugin is to place it in your WodPress' /wp-content/plugins/ directory. The easiest way to do this is to simple clone this repo in that directory:

  $ cd blog/wp-content/plugins/
  $ git clone https://github.com/drbobbeaty/CodeHighlighterPlus.git

at this point, the plugin will be available, but not active - activate it on the WordPress admin console.

From now on, you can get updates to this plugin with a simmple:

  $ cd blog/wp-content/plugins/CodeHighlighterPlus
  $ git pull

and it's up to date. This makes it easy to control the updates, and not have themm automatically done.

Usage

Once the plugin is activated, adding a highlighted code snippet to a post is pretty simple. You simply encase the code in the pre tag, and add in two optional attributes: lang and lineno.

For example, if I wanted to put the commands for updating the plugin into a post I would write:

<pre lang="bash">
  $ cd blog/wp-content/plugins/CodeHighlighterPlus
  $ git pull
</pre>

and if I needed to include line numbers, that would be as easy as:

<pre lang="bash" lineno="433">
    /**
     * Line number styles
     * @var string
     */
    protected $line_style1 = 'font-weight: normal; vertical-align:top;';
</pre>
