function locale_translation_source_check_file

Checks whether a po file exists in the local filesystem.

It will search in the directory set in the translation source. Which defaults to the "translations://" stream wrapper path. The directory may contain any valid stream wrapper.

The "local" files property of the source object contains the definition of a po file we are looking for. The file name defaults to %project-%version.%language.po. Per project this value can be overridden using the server_pattern directive in the module's .info.yml file or by using hook_locale_translation_projects_alter().

Parameters

object $source: Translation source object.

Return value

object Source file object of the po file, updated with:

• "uri": File name and path.
• "timestamp": Last updated time of the po file.

FALSE if the file is not found.
