This allows text editors to use correct syntax coloring for the heredoc sections.
Heredoc tag names we use:
languages: SQL, JS, RUBY, LUA, HTML, CSS, SCSS, SH, HBS, XML, YAML/YML, MF, ICS
other: MD, TEXT/TXT, RAW, EMAIL
This adds a new property, `pluginId` which you can pass to `modifyClass`
which prevent the class from being modified over and over again.
This also includes a fix for polls which was leaking state between tests
which this new functionality exposed.
The `details_enabled` site setting description did not clearly convey what it controls.
The copy change was discussed here: https://meta.discourse.org/t/183923
- removes the option from site settings
- deletes the site setting on existing sites that have it
- marks posts using emojis as requiring a rebake
Note that the actual image files are not removed here, the plan is to
remove them in a few weeks/months (when presumably the rebaking of old
posts has been completed).
Using arrow functions changes `this` context, which is undesired in tests, e.g. it makes it impossible to setup things like pretender (`this.server`) in `beforeEach` hooks.
Ember guides always use classic functions in examples (e.g. https://guides.emberjs.com/release/testing/test-types/), and that's what it uses in its own test suite, as do various addons and ember apps.
It was also already used in Discourse where `this` was required. Moving forward, it will be needed in more places as we migrate toward ember-cli.
(I might later add a custom rule to eslint-discourse-ember to enforce this)
In newer Embers jQuery is removed. There is a `find` but it only returns
one element and not a jQuery selector. This patch migrates our code to a
new helper `queryAll` which allows us to remove the global.
