Found a quick fix - turns out current function name includes "$O", a non-word character which will not match "\w+". Change cipher.py line 30 to: (Edited to include @ghrist8p's comment) var_regex = re.compile(r"^[\w\$_]+\W") I do not know all the possible patterns, but...
To ignore all unescaped white space characters and comments (denoted by the un-escaped hash#character and the next new-line character) in the pattern, include thesoption in theoptionsfield: // Specify xin the optionsfield {$regexMatch:{input:"$description",regex:/line/,options:"x"} } ...
