Constants should always be only assigned once. The logical OR assignment
of a constant is a relic of the past before we used zeitwerk for
autoloading and had bugs where a file could be loaded twice resulting in
constant redefinition warnings.
This patch upgrades the MessageFormat library to version 3.3.0 from
0.1.5.
Our `I18n.messageFormat` method signature is unchanged, and now uses the
new API under the hood.
We don’t need dedicated locale files for handling pluralization rules
anymore as everything is now included by the library itself.
The compilation of the messages now happens through our
`messageformat-wrapper` gem. It then outputs an ES module that includes
all its needed dependencies.
Most of the changes happen in `JsLocaleHelper` and in the `ExtraLocales`
controller.
A new method called `.output_MF` has been introduced in
`JsLocaleHelper`. It handles all the fetching, compiling and
transpiling to generate the proper MF messages in JS. Overrides and
fallbacks are also handled directly in this method.
The other main change is that now the MF translations are served through
the `ExtraLocales` controller instead of being statically compiled in a
JS file, then having to patch the messages using overrides and
fallbacks. Now the MF translations are just another bundle that is
created on the fly and cached by the client.
We want to allow admins to make new required fields apply to existing users. In order for this to work we need to have a way to make those users fill up the fields on their next page load. This is very similar to how adding a 2FA requirement post-fact works. Users will be redirected to a page where they can fill up the remaining required fields, and until they do that they won't be able to do anything else.
DEV: Replace instances of Discourse.base_uri with Discourse.base_path
This is clearer because the base_uri is actually just a path prefix. This continues the work started in 555f467.
Minor fixes to add Rails 6 support to Discourse, we now will boot
with RAILS_MASTER=1, all specs pass
Only one tiny deprecation left
Largest change was the way ActiveModel:Errors changed interface a
bit but there is a simple backwards compat way of working it
FIX: client's translation overrides were not working when the current locale was missing a key
FIX: ExtraLocalesController.show was not properly handling multiple translations
FIX: JsLocaleHelper#output_locale was not properly handling multiple translations
FIX: ExtraLocalesController.show's spec which was randomly failing
FIX: JsLocaleHelper#output_locale was muting cached translations hashes
REFACTOR: move 'enableVerboseLocalization' to the 'localization' initializer
REFACTOR: remove unused I18n.js methods (getFallbacks, localize, parseDate, toTime, strftime, toCurrency, toPercentage)
REFACTOR: remove all I18n.pluralizationRules and instead use MessageFormat's pluralization rules
TEST: add tests for localization initializer
TEST: add tests for I18n.js
