bhsd e4eb2846c9 fix scroll behavior of CodeMirror 6 
Previously, the CM6 editor always scrolls into view, which is annoying during preview. With this patch, the CM6 editor only scrolls to the selection while the whole webpage does not scroll. In addition, the editor's scroll position will be memorized when previewing.

This patch requires an update of the @codemirror/view package.

Development

As part of the upgrade to CodeMirror 6, CodeMirror now uses an asset bundler, so during development you'll need to run a script to assemble the frontend assets.

Use of CodeMirror 6 is controlled by the wgCodeMirrorV6 configuration setting, or by passing in cm6enable=1 in the URL query string.

You can find the v6 frontend source files in src/, the compiled sources in resources/dist/, and other frontend assets managed by ResourceLoader in resources/*.

Commands

NOTE: Consider using Fresh to run these tasks.

  • npm install to install dependencies.
  • npm start to run the bundler in watch mode, reassembling the files on file change. You'll want to keep this running in a separate terminal during development.
  • npm run build to compile the production assets. You must run this step before sending the patch or CI will fail (so that sources and built assets are in sync).
  • npm test to run the linting tools, JavaScript unit tests, and build checks.
  • npm run test:lint for linting of JS/LESS/CSS.
  • npm run test:lint:js for linting of just JavaScript.
  • npm run test:lint:styles for linting of just Less/CSS.
  • npm run test:i18n for linting of i18n messages with banana-checker.
  • npm run test:unit for the new Jest unit tests.
  • npm run selenium-test for the Selenium tests.
  • npm run test:bundlesize to test if the gzip'd entrypoint is of acceptable size.

Older QUnit tests are in resources/mode/mediawiki/tests/qunit/. These will eventually be moved over to tests/qunit and rewritten for CodeMirror 6.

CodeMirror 6 change log

This is a list of changes that either come by default with the CodeMirror 6 upgrade, or changes of our that we deem as reasonable improvements. Some may be removed pending user feedback:

Upstream changes

  • Bracket matching now highlights unmatched brackets in red

New MediaWiki mode features

  • Closing HTML tags that highlighted as an error now also highlight the closing '>'
  • Allow link titles to be both emboldened and italicized.

Deprecations and other changes

  • The .cm-mw-mnemonic CSS class has been renamed to .cm-mw-html-entity
  • The .cm-mw-template-name-mnemonic class has been removed. Use .cm-mw-template-ground.cm-html-entity instead.
  • Line-level styling for <nowiki>, <pre>, and any tag without an associated TagMode has been removed.
  • The browser's native search functionality (ala Ctrl+F) has been replaced with search functionality built into CodeMirror. This is necessary to maintain performance (see T303664).
