|
|
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.
