Module:File/doc

Scope

File title and file information. If the code here grows beyond a border line, this should be converted to an interface and the processing code should be outsourced.

Usage

Note that an error is thrown, if the title can't be constructed (e.g. a title containing invalid characters is supplied) or meta data isn't available (e.g. due to missing file or extraction error). It is your responsibility to catch them; in Lua through pcall(); from Wikitext as {{#iferror: {{#invoke:File|function|file=File:P%bar]baz.qqq}} | meaningful message}}.
