Plugin / Syntax-highlighting Code Block (with Server-side Rendering)

Weston Ruter

Description

Description

This plugin extends to Code block in WordPress core to add syntax highlighting which is rendered on the server. By performing the syntax highlighting on the server, there is then no need to enqueue any JavaScript on the frontend (e.g. Highlight.js or Prism.js) and this ensures there is no flash of unhighlighted code (FOUC?). Reducing script on the frontend improves frontend performance and it also allows for the syntax highlighted code to appear properly in AMP pages as rendered by the official AMP plugin (see also ampproject/amp-wp#972).

The extended Code block uses auto-detection for the language in the block to add syntax highlighting, but you can override the language in the block inspector. (There is currently no syntax highlighting of the Code block in the editor.) The plugin supports for all 185 programming languages that highlight.php supports (being a port of highlight.js).

Any one of 89 styles may be enqueued that highlight.php/highlight.js provide. To override the default style, use the syntax_highlighting_code_block_style to supply the one of the style names, for example github:

add_filter(
    'syntax_highlighting_code_block_style',
    function() {
        return 'github';
    }
);

This plugin is developed on GitHub. See list of current issues with the plugin. Please feel free to file any additional issues or requests that you may come across. Pull requests are welcome to help extend.
