Extracts translations by recompiling the Elixir source code.

mix gettext.extract [OPTIONS]

Translations are extracted into POT (Portable Object Template) files (with a .pot extension). The location of these files is determined by the :otp_app and :priv options given by Gettext modules when they call use Gettext. One POT file is generated for each translation domain.

All automatically extracted translations are assigned the ex-autogen flag. If a translation from the POT is no longer present and has the ex-autogen flag, the translation will be removed.

If you would like to verify that your POT files are up to date with the current state of the codebase, you can provide the --check-up-to-date flag. This is particularly useful for automated checks and in CI systems. This validation will fail even when the same calls to gettext only change location in the codebase:

mix gettext.extract --check-up-to-date

It is possible to give the --merge option to perform merging for every Gettext backend updated during merge:

mix gettext.extract --merge

All other options passed to gettext.extract are forwarded to the gettext.merge task (Mix.Tasks.Gettext.Merge), which is called internally by this task. For example:

mix gettext.extract --merge --no-fuzzy
