Description

This project is adding CodeMirror functionality to the Plugin and Theme file editors, as well as the Customizer Custom CSS box and the Custom HTML widget.

This is currently a Work In Progress playground for experimenting with bringing syntax highlighting to WordPress Core.

We’re working around discussion on a Core ticket, #12423

Getting Started

You can locate a ZIP for this plugin on the releases page on GitHub. To install, simply go to your WP Admin and Plugins > Add New. Then click “Upload Plugin” and select the codemirror-wp.zip you downloaded from the releases page. Then click “Install Now” and on the next screen click “Activate Plugin”. Note on upgrading: If you want to update the plugin from a previous version, you must first deactivate it and uninstall it completely and then re-install and re-activate the new version (see #9757 for fixing this).

Otherwise, to set up the plugin for development: clone this repository and run npm install to download CodeMirror and other assets.

cd wp-content/plugins/
git clone --recursive https://github.com/WordPress/codemirror-wp.git
cd codemirror-wp
npm install

Also install the pre-commit hook via:

`bash

cd .git/hooks && ln -s ../../dev-lib/pre-commit pre-commit && cd –
`

Creating a Release

Contributors who want to make a new release, follow these steps:

1. Bump plugin versions in package.json (×1), package-lock.json (×1, just do npm install first), readme.txt (×1 in Stable Tag), and in codemirror-wp.php (×2: the metadata block in the header and also the CodeMirror_WP::VERSION constant).
2. Run npm run build-release-zip to create a codemirror-wp.zip in the plugin’s root directory.
3. Create new release on GitHub targeting master, with the new plugin version as the tag and release title, and upload the codemirror-wp.zip as the associated binary. Publish the release.
