Editor: Add CodeMirror-powered code editor with syntax highlighting, linting, and auto-completion.

  • Code editor is integrated into the Theme/Plugin Editor, Additional CSS in Customizer, and Custom HTML widget. Code editor is not yet integrated into the post editor, and it may not be until accessibility concerns are addressed.
  • The CodeMirror component in the Custom HTML widget is integrated in a similar way to TinyMCE being integrated into the Text widget, adopting the same approach for integrating dynamic JavaScript-initialized fields.
  • Linting is performed for JS, CSS, HTML, and JSON via JSHint, CSSLint, HTMLHint, and JSONLint respectively. Linting is not yet supported for PHP.
  • When user lacks unfiltered_html the capability, the Custom HTML widget will report any Kses-invalid elements and attributes as errors via a custom Kses rule for HTMLHint.
  • When linting errors are detected, the user will be prevented from saving the code until the errors are fixed, reducing instances of broken websites.
  • The placeholder value is removed from Custom CSS in favor of a fleshed-out section description which now auto-expands when the CSS field is empty. See #39892.
  • The CodeMirror library is included as wp.CodeMirror to prevent conflicts with any existing CodeMirror global.
  • An wp.codeEditor.initialize() API in JS is provided to convert a textarea into CodeMirror, with a wp_enqueue_code_editor() function in PHP to manage enqueueing the assets and settings needed to edit a given type of code.
  • A user preference is added to manage whether or not "syntax highlighting" is enabled. The feature is opt-out, being enabled by default.
  • Allowed file extensions in the theme and plugin editors have been updated to include formats which CodeMirror has modes for: conf, css, diff, patch, html, htm, http, js, json, jsx, less, md, php, phtml, php3, php4, php5, php7, phps, scss, sass, sh, bash, sql, svg, xml, yml, yaml, txt.
