  • Resolved Weston Ruter


    Greetings! I wanted to reach out to you as author of syntax-highlighter-for-wp-editor (and to authors of other plugins like yours) and let you know that CodeMirror is currently being integrated into WordPress, specifically in the Theme & Plugin editors, Custom HTML widget, and Additional CSS in the Customizer (integration with the Text tab of the post editor is not currently in scope).

    The goal is to release core with CodeMirror in 4.9, the current release in development. The initial merge of CodeMirror is being planned for trunk (4.9-alpha) within the next couple weeks. Given that your plugin also integrates CodeMirror, I wanted to alert you to this upcoming change, since it will likely mean your plugin will need changes to be compatible with 4.9. Additionally, given your experience in working with CodeMirror, I wanted to reach out to see if you wanted to review and contribute what is being worked on for core.

    The feature plugin can be found on GitHub:

    We appreciate your feedback. Thank you!
