Codeblocks

Description

Codeblocks lets you add highlighted and formatted source code into your website without cluttering the visual editor. Write your code in individual blocks outside the built-in Content editor, and access these blocks simply by adding [codeblock name='MY_BLOCK'] into your blog post or page. Codeblocks highlights the code on your website using Rainbow.js, and themes can customize the color scheme of your code.

Theme editors: See the Installation section for information on how to adjust Codeblocks options in your theme.

Theme Editors

You can hook into codeblocks/rainbow_theme filter inside your functions.php file to change the Rainbow.js theme (there are many themes on GitHub). Return a URL to the new theme stylesheet file, or null to disable highlighting, or true to only include the Rainbow.js file without a theme (useful if your themes already-loaded stylesheet file contains the code highlighting styles). Here’s a few examples:

add_filter('codeblocks/rainbow_theme', function($oldURL) {

    // Use the file 'cool-rainbow.css' inside our theme directory

    return plugins_url('cool-rainbow.css', __FILE__);
});

You can also disable code highlighting with your theme by returning null in the filter.

add_filter('codeblocks/rainbow_theme', function($oldURL) {

    // Disable code highlighting on our theme

    return null;
});

If your theme’s base stylesheet file already includes the Rainbow.js styles, just return true and we’ll skip importing the stylesheets, and just load the Rainbow.js plugin.

add_filter('codeblocks/rainbow_theme', function($oldURL) {

    // Add Rainbow.js tags, but don't include a separate stylesheet file

    return true;
});

Screenshots

  • Codeblocks adds source code editors below your main post body.

Installation

The plugin is simple to install:

  1. Download the Codeblocks plugin file (.zip)
  2. Unzip and upload the plugin files folder to your wp-content/plugins folder
  3. Go to the Plugins page and activate the Codeblocks plugin

While writing a post or page in your blog, add your code in the Codeblocks section of the Edit page. If this section does not show up, open the Screen Options dropdown from the top of the page and make sure Codeblocks is checked.

In your article content, you can access your blocks of code using [codeblock name='MY_BLOCK'] where MY_BLOCK is whatever you titled your block of code. Codeblocks will automatically take care of setting up the highlighting feature on your website.
