Utility functions to help creating modules

def(value, default)

Returns value if it is not nil or "", and defaultotherwise

_a(arg)

Extracts the argument from the common ways mediawiki passes arguments to modules:

if arg is not a table, it is returned as is (Called from Lua like a function)
if arg is a table and that table has a args field, arg.args[1] is returned (Called from MediaWiki’s {{#invoke:}} parser function)
if arg is a table but doesn’t contain an args field, args[1] is returned (Called with a table as an argument list^[1])

date(y, m, d, short = false)

Formats a date.

If short</text> is set to true, uses shortened months name instead of full length month names.


↑ Some mediawiki functions do that, idk why — Annwan
