The typeahead suggests a human-readable `pretty_name` for the
`language` field in the add-playgrounds form.
The suggestions are sorted based on the popularity of these
languages.
E.g: A `py` prefix would match with `Python` first before
matching with others like `Python 2.x` based on priority.
The UI makes use of an onclick on the trash icon to call
DELETE /realm/playground/{playground_id}. The id is
extracted from the data attribute `data-playground-id`
set on that element.
The design of the form is similar to the linkifiers page
and is styled similarly.
The introduction text for "Code playgrounds" is improved
with more details and examples.
Also, we can remove the hardcoded playground and the fix
we had previously done to prevent breaking the hardcoded
playground.
Adds a setting UI to list all configured playgrounds
in a realm. The filter functionality can be used to
search playgrounds by its name or language.
Default sort is provided on the 'pygments_language'
field.
Front tests added to maintain server_event_dispatch
coverage. The `settings_playgrounds.js` file is added
to coverage exclusion list since it is majorly UI
based and will be tested using puppeteer tests (in
following commits).
