Change Details

This is the first step of {T259059}. This will only put us in a basic working state with CodeMirror 6, with everything behind a temporary feature flag. The actual syntax highlighting and other features are to follow. **Acceptance criteria** * Using the [[ https://www.npmjs.com/package/codemirror | basic CodeMirror package ]], identify which modules under the `@codemirror` namespace we need. * Create new `ext.CodeMirror.v6.WikiEditor` module that is loaded when `$wgCodeMirrorV6` is set or if the `cm6enable=1` URL query parameter is set. * Visually, enabling CodeMirror should give you a monospaced text editor without any syntax highlighting. Relevant features of #wikieditor should still work, and you should still be able to save the page, etc.

The actual syntax highlighting and other features are to follow. **Acceptance criteria** * Using the [[ https://www.npmjs.com/package/codemirror | basic CodeMirror package ]], identify which modules under the `@codemirror` namespace we need. ** As CodeMirror 6 uses [[ https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules | native JavaScript Modules ]], use a bundle system as necessary to feed into ResourceLoader. * Create new `ext.CodeMirror.v6.WikiEditor` module that is loaded when `$wgCodeMirrorV6` is set or if the `cm6enable=1` URL query parameter is set. * Visually, enabling CodeMirror should give you a monospaced text editor without any syntax highlighting. ** Relevant features of #wikieditor should still work (no exhaustive testing necessary), and you should still be able to save the page, etc. ** Identify any other integrations that are apparently now broken, and document them (we're not going to enable `$wgCodeMirrorV6` anytime soon so some breakage is expected)
