# `GettextTranslator.Util.PoHelper`
[🔗](https://github.com/marmend-company/gettext_translator/blob/main/lib/gettext_translator/util/po_helper.ex#L1)

Helpers for updating `Expo.Message` structs with translation entries.

# `get_message_id`

# `update_po_message`

Updates a PO message with a new translation.

For plural messages the PO file itself defines how many plural forms the
language uses (one `msgstr[n]` per form), so only the forms tracked by the
translation entry (`msgstr[0]` and `msgstr[1]`) are replaced. Higher forms
(`msgstr[2]`+) already present in the file are preserved as-is; they are only
filled with the generic plural translation when still empty, so newly
translated messages don't end up with blank forms.

An explicit `:plural_translation_2` key on the translation entry overrides
`msgstr[2]` when present and non-empty.
