A neat regex for finding out whether a given torrent name is a series or a movie. Returns the full name of the series with the separator needed to make it pretty (ie, replace it with space or what you want). Also returns the season number or the year for the movie/series, depending on what was previously matched.

Variable name of code

Created·2015-09-19 11:18

Flavor·PCRE (Legacy)

To get a variable name from a source code: The variable name is before the '=' (equal sign) This is the way to detect. Problem: Only 1 variable can get from 1 line. Unfortunately, this can get variable between after "//" and before ";" too. I made this for fake script debugger. Just get variable from source code and put that after last semicolon with so much tab and messagebox code for every line.
