Snippets Shortcode

Custom post type to hold Code Snippets. A Shortcode is provided to show code blocks in the frontend. Uses CodeMirror in the backend.

In the frontend, Snippets can be shown in plain text, with CodeMirror or with WP-Syntax.

Based in this WordPress Answer: Create custom [sourcecode] shortcode, the right way?

FAQ

Use with WP-Syntax

Install the plugin, and a shortcode will be available to render compatible content.

More than one CodeMirror shortcode

This is not working. Only one CM shortcode can be at each page/post.
Use WP-Syntax instead.
