Confused

I'm still really confused as to how to use this. What is \1? What in the regex indicates more values like \1 \3? Are they like parameters of the regex? Please explain it as simply as possible. Lectrician1 (talk) 00:50, 20 January 2021 (UTC)

• What are you trying to do with it? It might be easier to explain it in relation to your usecase. --- Jura 01:31, 20 January 2021 (UTC)

I want to fix the required qualifier constraint (Q21510856) suggestion flag on the URL match pattern (P8966) property in LittleSis organization ID (P3393). Lectrician1 (talk) 05:29, 20 January 2021 (UTC)

It's optional there. I removed the constraint [1]. --- Jura 15:32, 20 January 2021 (UTC)

Pretty sure \1 is meant to indicate a regex capturing group (anything inside () but not if it has ?: in it) which is confusing since formatter URL (P1630) uses $1 to indicate a regex capturing group. - I is chan (talk) 17:07, 11 July 2022 (UTC)

Change the case

Have come across this a few times, the unique ID itself should be in capitals but the websites that use it don't care, for example IATA airport code (P238) should be three uppercase letters, however "flight radar" uses lowercase https://www.flightradar24.com/airport/bqh

Can "URL match replacement value" take the captured value "bqh" and convert it "BQH"  ? Back ache (talk) 02:17, 9 March 2022 (UTC)

Just replace "bqh" with "(?:bqh|BQH)" this will allow for both all lowercase and all uppercase but BqH will not work - I is chan (talk) 17:10, 11 July 2022 (UTC)

Sorry I think I misread, bqh is the value? I don't think it is possible to convert cases with regex, you'll have to convert the case via some other method like a program before using it. - I is chan (talk) 17:17, 11 July 2022 (UTC)

I think I found something: \U\1 the \U converts the captured group in uppercase I'm not sure if this is supported in wikidata tools or anything though - I is chan (talk) 17:21, 11 July 2022 (UTC)
