Motivation edit

This will provide a way to extract property and ID from a given URL. A future tool or gadget may benefit from this. GZWDer (talk) 23:46, 26 February 2020 (UTC)[reply]

Discussion edit

  Comment Here's an example of how this would look on Fandom article ID (P6262):

URL match pattern
  https:\/\/([a-z0-9\.-]+)\.(wikia|fandom)\.com\/wiki\/(.*) edit
URL match replacement value \1:\3

If a tool wanted to automatically generate a Fandom article ID (P6262) from the URL https://minecraft.fandom.com/wiki/Sheep for example, it would match the regex specified with property against that URL. There are three caputring groups in the regex. The first one is ([a-z0-9\.-]+), and matches "minecraft", the second one is (wikia|fandom) and matches "fandom", and the third one is (.*) and matches "Sheep". The URL match replacement value allows these capturing groups to be put together. \1:\3 turns into minecraft:Sheep, since \N is replaced with the value of the nth capturing group. --SixTwoEight (talk) 01:52, 4 March 2020 (UTC)[reply]

Replacement for external id extraction

  •   Comment Thanks for the ping Lockal. Something like this will almost certainly help. I don't have time right now to get my head around the alternatives, but I'm very glad to see this. --99of9 (talk) 11:17, 6 October 2020 (UTC)[reply]
  • @GZWDer:, sorry for interruption, what do you think about my suggestion above (about reusing of applies if regular expression matches)? Also, inversion of pattern/replacement creates somewhat cleaner representation in case when different URL patterns are using the same replacement (which is impossible it an opposite way: a single URL pattern can never use multiple replacement patterns). If you agree, could you update your proposal, please? --Lockal (talk) 07:58, 13 October 2020 (UTC)[reply]
