defmodule Pleroma.Web.Gettext do
@moduledoc """
A module providing Internationalization with a gettext-based API.
By using [Gettext](https://hexdocs.pm/gettext),
your module gains a set of macros for translations, for example:
import Pleroma.Web.Gettext
# Simple translation
gettext "Here is the string to translate"
# Plural translation
ngettext "Here is the string to translate",
"Here are the strings to translate",
3
# Domain-based translation
dgettext "errors", "Here is the error message to translate"
See the [Gettext Docs](https://hexdocs.pm/gettext) for detailed usage.
