Stephen Niedzielski 676faa3514 Hygiene: consolidate CSS class manipulation
• Instead of removing 'mwe-popups-no-image-tri' in
  renderer#layoutPreview(), add more conditions to #getClasses().

  The addition condition in getClasses() was:

    ( !hasThumbnail || isTall ) && !flippedY

  The removal condition in layoutPreview() was:

    flippedX && !flippedY && hasThumbnail && isTall

  To combine them, the removal logic is inverted and the conjunction is
  taken:

    ( ( !hasThumbnail || isTall ) && !flippedY ) &&
    !( flippedX && !flippedY && hasThumbnail && isTall )

  Push the negation inwards:

    ( !hasThumbnail && !flippedY || isTall && !flippedY ) &&
    ( !flippedX || flippedY || !hasThumbnail || !isTall )

  Expand:

    !hasThumbnail && !flippedY && !flippedX ||
    !hasThumbnail && !flippedY && flippedY ||
    !hasThumbnail && !flippedY && !hasThumbnail ||
    !hasThumbnail && !flippedY && !isTall ||
    isTall && !flippedY && !flippedX ||
    isTall && !flippedY && flippedY ||
    isTall && !flippedY && !hasThumbnail ||
    isTall && !flippedY && !isTall

  Eliminate always false conditions and combine redundancies:

    !hasThumbnail && !flippedY && !flippedX ||
    !hasThumbnail && !flippedY ||
    !hasThumbnail && !flippedY && !isTall ||
    isTall && !flippedY && !flippedX ||
    isTall && !flippedY && !hasThumbnail

  Further eliminate redundancies:

    !hasThumbnail && !flippedY ||
    isTall && !flippedY && !flippedX ||
    isTall && !flippedY && !hasThumbnail

  Factor:

    !flippedY && (
      !hasThumbnail || isTall && !flippedX || isTall && !hasThumbnail
    )

  Factor more:

    !flippedY && (
      !hasThumbnail || isTall && ( !flippedX || !hasThumbnail )
    )

  Eliminate last redundancies:

    !flippedY && ( !hasThumbnail || isTall && !flippedX )

  The getClasses() test is updated for the new logic.

• Move thumbnail clip path manipulation from renderer#layoutPreview() to
  a new function, #setThumbnailClipPath(). The new function flips the
  order of the series of if statements so that an if / else block can be
  used instead which clarifies that clip-path state is exclusive. In
  other words:

    if ( a ) { foo.prop = 1; }
    if ( b ) { foo.prop = 2; }
    if ( c ) { foo.prop = 3; }
    if ( d ) { foo.prop = 4; }

  Can generically be refactored regardless of condition or value to:

    if ( d ) { foo.prop = 4; }
    else if ( c ) { foo.prop = 3; }
    else if ( b ) { foo.prop = 2; }
    else if ( a ) { foo.prop = 1; }

  Because prop was originally overwritten which implies if / else-like
  priority.

  Additionally:
  • The entire function call is wrapped in a hasThumbnail conditional
    which previously was checked as an input in each case.
  • Consolidate the last two conditions since they only differed by a
    single boolean input.
  • Move the setAttribute() action to the end of the function since the
    conditionals just map condition to value and the action is now
    identical.

• Revise pokey mask doc to use clip-path terminology. This inverts the
  thinking about the mask but better matches usage.

Popups

mediawiki/extensions/Popups

See https://www.mediawiki.org/wiki/Extension:Popups for more information about what it does.

Development

Popups uses an asset bundler so when developing for the extension you'll need to run a script to assemble the frontend assets.

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

After an npm install:

  • On one terminal, kickstart the bundler process:
    • npm start Will run the bundler in watch mode, re-assembling the files on file change.
    • npm run build Will compile the assets just once, ready for deployment. You must run this step before sending the patch or CI will fail (so that sources and built assets are in sync).
  • On another terminal, run tests and linting tools:
    • npm test To run the linting tools and the tests.
      • You can find the QUnit tests that depend on running MediaWiki under tests/qunit/
      • You can find the isolated QUnit tests under tests/node-qunit/, which you can run with npm run test:node
    • We recommend you install a file watcher like nodemon to watch sources and auto run linting and tests.
      • npm install -g nodemon
      • Example running linting and node unit tests:
        • nodemon -w src/ --exec "grunt lint:all && npm run test:node"
    • Get code coverage report with npm run coverage
      • Reports printed in the coverage/ folder

Developers are likely to work with local MediaWiki instances that do not have content to test with. To reduce this pain, you can create a single page with a list of links that point to an existing and external wiki by using the following config flag:

$wgPopupsGateway = 'restbaseHTML';
$wgPopupsRestGatewayEndpoint = 'https://en.wikipedia.org/api/rest_v1/page/summary/';

Popups works with a local copy of the Mobile Content Service too:

$wgPopupsGateway = 'restbaseHTML';
$wgPopupsRestGatewayEndpoint = 'http://localhost:6927/en.wikipedia.org/v1/page/summary/';
