Automatic, Supervised, or Manual: automatic

Programming language(s): AWB

Source code available: AWB

Function overview: Remove UTM parameters (Google analytics) from external links and references (i.e. resurrect Theo's Little Bot task #23)

Links to relevant discussions (where appropriate): Wikipedia:Bot requests/Archive 55#Remove Google Analytics tracking from external links

Edit period(s): Once a month

Estimated number of pages affected: 16000 in the initial run, and maybe 200 a month after that? Theo's task ran in batches of 500, which also works, but I couldn't then give a timeframe.

Exclusion compliant (Yes/No): Yes

Already has a bot flag (Yes/No): Yes

Function details: Straight-forward find-and-remove. Regex:

• \??(?:&?utm_[^=]*?=[^&\s\]\|]*)+(?=]|\s|\|)|(?<=\?)(?:&?utm_[^=]*?=[^&\s\]\|]*)+& (test cases)
• \??(?:&?utm_[^=\s]*?=[^&\s\]\|]*?)+(?=<|}|]|\s|\|)|(?<=\?)(?:&?utm_[^=\s]*?=[^&\s\]\|]*)+&|(?<=&)(?:&?utm_[^=\s]*?=[^&\s\]\|]*)+& (tests)

As near as I can tell, I've managed to cover all of the edge cases which were of concern in the original BRFA. The blue section covers the case where ?utm_ is followed by an & not followed by another utm_ (e.g. ?utm_example=1234&para=value). The red hits everything else (i.e. where the utm_ term(s) are only at the end of the URL). Green is when utm falls in between two other codes
