> Low-level [GNU gettext][gettext] file handling (for `.po`, `.pot`, and `.mo`
|
||
|
|
> files), including writing and parsing.
|
||
|
|
|
||
|
|
See [the documentation][docs].
|
||
|
|
|
||
|
|
For a full Gettext integration, see the [Gettext library][elixir-gettext].
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Expo can *parse* PO, POT, and MO files from [GNU gettext][gettext]:
|
||
|
|
|
||
|
|
```elixir
|
||
|
|
Expo.PO.parse_file!("priv/gettext/default.pot")
|
||
|
|
#=> %Expo.Messages{...}
|
||
|
|
```
|
||
|
|
|
||
|
|
It can also *write* well-formed PO, POT, and MO files:
|
||
|
|
|
||
|
|
```elixir
|
||
|
|
"priv/gettext/default.pot"
|
||
|
|
|> Expo.PO.parse_file!()
|
||
|
|
|> Expo.PO.compose()
|
||
|
|
|> then(fn content -> File.write!("priv/gettext/copy.pot") end)
|
||
|
|
```
|
||
|
|
|
||
|
|
This library can also parse [`Plural-Form`
|
||
|
|
headers](https://www.gnu.org/software/gettext/manual/html_node/Plural-forms.html)
|
||
|
|
in PO or POT files, and ships with a built-in list of languages and their plural
|
||
|
|
forms. You can find which plural form to use for a given *amount* by using
|
||
|
|
`Expo.PluralForms.index/2`:
|
||
|
|
|
||
|
|
```elixir
|
||
|
|
{:ok, plural_form} = Expo.PluralForms.plural_form("de")
|
||
|
|
|
||
|
|
Expo.PluralForms.index(plural_form, 1)
|
||
|
|
#=> 0
|
||
|
|
Expo.PluralForms.index(plural_form, 213)
|
||
|
|
#=> 1
|
||
|
|
```
