Pf4wp is POEdit friendly. MO files should be located in the plugin's /resources/l10n directroy, stored as locale + .mo, for example en-US.mo. They will be automatically loaded by Pf4wp, based on the current locale and availability.
By default, POEdit does not have the ability to import Twig templates. This can be resolved by adding an additional parser (Edit -> Preferences -> Parsers) with the following options:
- Language:
Twig - List of extensions:
*.twig - Invocation:
- Parser command:
xgettext --force-po -LPython -o %o %C %K %F - An item in keyword list:
-k%k - An item in input file list:
%f - Source code charset:
--from-code=%c
- Parser command:
Then as keywords you need to use __ (double underscore).
Pf4wp offers both a Twig filter and Twig function for translations.
The function is called using the double underscore as following:
{{ __('Hello World') }}
The filter, called trans can be used as following:
{{ 'Hello World' | trans }}
The drawback of using the filter is that it will not be picked up by POEdit as a translatable string. It is possible to use the view cache instead, usually stored in store/cache/views, and to use the keyword transFilter.
