@lingui/format-po-gettext

Read and write message catalogs in Gettext PO format with gettext-style plurals
Converts ICU Plural expressions into native gettext plurals

@lingui/format-po-gettext is part of LinguiJS. See the documentation for all information, tutorials and examples.

Warning This formatter is made for compatibility with translation management systems, which do not support ICU expressions in PO files.
It does not support all features of LinguiJS and should be carefully considered over other formats.
Not supported features (native gettext doesn't support this):
SelectOrdinal
Select
Nested ICU Expressions
Signed digits and fractions (-5, and 0.15) in plurals
