Module:Unsigned: Difference between revisions

Module documentation[view] [edit] [history] [purge]

This module implements {{unsigned}}. It has a few functions:

• main called by {{unsigned}}; not intended for broader use
• getTimestamp find a timestamp from a string. If only a date is found, it returns the date. If only a time is found, it returns the empty string. If a time and a date are both found, it appends (UTC).
• getUsername gets the username from a string containing a timestamp. It currently assumes that everything besides a timestamp is part of the username.

-- There's probably a way to use strptime or some other more sophisticated way, but you're not supposed to be using a non-timestamp as input anyway.
