Method: AuthModule#parse_args

Defined in:
lib/rbot/core/auth.rb

#parse_args(ar, setting) ⇒ Object

The permission parameters accept arguments with the following syntax:

cmd_path... [on #chan .... | in here | in private]

This auxiliary method scans the array ar to see if it matches the given syntax: it expects + or - signs in front of cmd_path elements when setting = true

It returns an array whose first element is the array of cmd_path, the second element is an array of locations and third an array of warnings occurred while parsing the strings
