Add gettext as a required dependency

[trarbr]

This fixes compilation of Mix projects which have no explicit dependency on gettext.

I guess the dependency is no longer optional since gettext has been added to the list of compilers.

Thats very interesting, thanks for the report and PR.

I didn't expect that the project list of compilers would leak to an application using the library. Thats surprising. I have it in the ex_cldr_messages mix.exs for testing purposes.

My intention is that Gettext remain optional since not every use case requires it.

[trarbr]

Oh okay 😄 I just pulled ex_cldr_messages down to play around with the library a bit and noticed that version 0.12 did not compile. After a bit of troubleshooting I found that adding gettext as a dependency of my (otherwise empty) Mix project made it work.

Should the gettext compiler only be added in the test environment then?

Thanks for confirming. I will do as you suggest and make sure that it doesn't require Gettext. Thanks for the collaboration.

No problem, happy to help - and thank you so much for your work on the various ex_cldr projects ❤️

I have published ex_cldr_messages version 0.13.0 with the following changelog entry:

Bug Fixes

• Don't add :gettext to Mix.compilers/0 because it gets inherited into client applications and we want Gettext to remain optional. Thanks to @trarbr for the report.

• Fix typos. Thanks as always to @kianmeng

Enhancements

• Add an Elixir formatter plugin for sigil_M. For example in your .formatter.exs file:

[
  inputs: ["mix.exs", "{config,lib,test,mix}/**/*.{ex,exs}"],
  locals_without_parens: [docp: 1, defparsec: 2, defparsec: 3],
  plugins: [Cldr.Formatter.Plugin]
]

TIL that client apps inherit dependent mix compilers! Thanks for the report, the PR and the collaboration. I hope the experience is better now (although I am sure there are other issues waiting to be discovered).
