Distinguish torrent files (series vs movies)

Created·2014-06-26 09:59

Updated·2023-07-20 15:08

Flavor·Python

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.

UK Postcode Checker

Created·2014-10-21 08:23

Flavor·PCRE (Legacy)

Checks for valid UK/British postcodes. There was another on here that had for some reason been upvoted, but it was actually incorrect as it worked on none of my valid own postcodes! Namely that it assumed two letters and a number (BS3) when you can have variations (M20). Allows for an optional space and separates the two parts into groups.
