Unable to use regex to get substring from directory name

[ohrenkino]

here is a statement about the flavour:

What regex engine does mp3tag use?

perl flavor to a large extent

@jerblack

Also, FYI, the regex you posted returns the entire string if there is no match

Yes, that is the way the regexp machine works in MP3tag

@jerblack

. I previously read the doc blurb you pointed to and did not see anything about quote requirements or why the regex behavior is different in mp3tag.

See the Help on scripting:
$regexp(x,expr,repl) replaces the pattern specified by the regular expression expr in the string x by repl . The fourth optional parameter enables ignore case (1) or disables the ignore case setting (0). Please note that you have to escape comma and other special characters in expr .
