v0.26.2

Introduces warning if plural messages are defined with the same singular message and conflicting plural messages.
Improves performance by striping not required metadata when compiling the Gettext backend.

v0.26.1

Address backwards incompatible changes in previous release

v0.26.0

This release changes the way you use Gettext. We're not crazy: it does so because doing so makes it a lot faster to compile projects that use Gettext. The changes you have to make to your code are minimal, and the old behavior is deprecated so that you will be guided on how to update.

The reason for this change is that it removes compile-time dependencies from modules that used to import a Gettext backend. In applications such as Phoenix applications, where every view and controller imports the Gettext backend, this change means a lot less compilation when you make translation changes!

Here's the new API. Now, instead of defining a Gettext backend (use Gettext) and then importing that to use its macros, you need to:

Define a Gettext backend with use Gettext.Backend
Import and use its macros with use Gettext, backend: MyApp.Gettext.

Before and After

Before this release, code using Gettext used to look something like this:

defmodule MyApp.Gettext do
  use Gettext, otp_app: :my_app
end

defmodule MyAppWeb.Controller do
  import MyApp.Gettext
end

This creates a compile-time dependency for every module that imports the Gettext backend.

With this release, the above turns into:

defmodule MyApp.Gettext do
  use Gettext.Backend, otp_app: :my_app
end

defmodule MyAppWeb.Controller do
  use Gettext, backend: MyApp.Gettext
end

We are also updating Phoenix generators to use the new API.

If you update Gettext and still use use Gettext, otp_app: :my_app to define a backend, Gettext will emit a warning now.

Migration with Igniter

If your project is using igniter, you can run mix igniter.update_gettext to automatically migrate to the new API.

Detailed Changelog

This is a detailed list of the new things introduced in this release:

Add Gettext.Macros, which contains all the macros you know and love (*gettext). It also contains *gettext_with_backend variants to explicitly pass a backend at compile time and keep extraction working.
Document lgettext/5 and lngettext/7 callbacks in Gettext.Backend. These get generated in every Gettext backend.
Add the Gettext.domain/0 type.

v0.25.0

Run merging for mix gettext.extract's POT files even if they are unchanged.
Allow Expo 1.0+.

v0.24.0

Handle singular and plural messages with the same msgid as the same message.
This change produces a Expo.PO.DuplicateMessagesError if you already have messages with the same singular msgid. This can be solved by calling the expo.msguniq mix task on your .po file:
```
mix expo.msguniq \
  priv/gettext/LOCALE/LC_MESSAGES/DOMAIN.po \
  --output-file priv/gettext/LOCALE/LC_MESSAGES/DOMAIN.po
```

v0.23.1

Use the Hex version of the excoveralls dependency.

v0.23.0

Add the :custom_flags_to_keep Gettext option.

v0.22.3

Fix a bug with extracting translations in Elixir 1.15.0+.

v0.22.2

Use Code.ensure_compiled/1 instead of Code.ensure_loaded/1 for Elixir < 1.12 compatibility.
Ensure all modules are properly loaded for mix gettext.merge.
Fix a "protected" check when extracting translations.

v0.22.1

Put correct Plural-Forms header on gettext.merge for the first time.
Fix extractor crash in case of conflicting backends.
Fix to use the correct plural forms for multiple languages.
Update expo to ~> 0.4.0 to fix issues with empty msgstr.

v0.22.0

Deprecate (with a warning) the --plural-forms CLI option and the :plural_forms option in favor of --plural-forms-header and :plural_forms_header.
Supply the Plural-Forms header to Gettext.Plural callbacks.
Bump Expo requirement to ~> 0.3.0.
Add the types:
- Gettext.Interpolation.bindings/0
- Gettext.Error.t/0
- Gettext.Plural.locale/0
- Gettext.Plural.pluralization_context/0
- Gettext.Plural.plural_info/0
Add the optional callbacks Gettext.Plural.init/1 and Gettext.Plural.plural_forms_header/1.

Bug fixes

Fix --check-up-to-date with msgids split in different ways.
Don't write the same file more than once in references when using write_reference_line_numbers: false.

v0.21.0

New features and improvements

Bump Elixir requirement to 1.11+.
Extract parsing and dumping of PO/POT files to the expo library, and start depending on that.
Support marking messages as obsolete with the new :on_obsolete Gettext configuration option.

Bug fixes

Sort messages independent of line splits when dumping PO files.

v0.10.0

Emit warnings when the domain passed to one of the *gettext macros has slashes in it (as we don't support domains in subdirectories).
Discard dangling comments when parsing/dumping PO(T) files (dangling comments are comments that are not followed by a transaction they can be attached to).
Updated informative comments for newly generated PO/POT files.

v0.9.0

Strip ## comments from POT files when they're being merged into PO files; these comments are comments meant to be generated by tools or directed at developers (so they have no use for translators in PO files).
Add informative comments at the top of newly generated PO/POT files.
Add Gettext.known_locales/1
Fix a bug with PO parsing when the PO file starts with a BOM character (which broke the parser, now a warning is issued).

Create missing locale directories (for example, en/LC_MESSAGES) when running the gettext.merge Mix task.
Fallback to default messages (that is, the msgid) when the msgstr (or one or more msgstr strings for plural messages) is empty.

When dumping PO files, dump as many references as possible on one line, wrapping at the 80th column
Parse multiple references in the same reference comment
Remove Gettext.locale/0-1 and Gettext.with_locale/2 in favour of Gettext.get_locale/1, Gettext.put_locale/2, and Gettext.with_locale/3 which now work by setting/getting the locale on a per-backend basis (instead of a global one)
Remove the :default_locale config option for the :gettext application in favour of configuring the :default_locale for backends tied to their :otp_app (for example, config :my_app, MyApp.Gettext, default_locale: "pt_BR")

v0.6.1

Fix a bug with the mix gettext.merge task that was failing in Elixir v1.1.1 because 0.5 in 0..1 returns false with it
