Probably related to overall MetaBrainz issues, if I had to guess. I've had login issues on multiple projects in the past week

waait I just realised I could possibly fix BB-870 myself, https://bookbrainz.org/identifier-type/23/edit what should I edit the Detection RegEx and Validation RegEx with? (can replace just "authors" with "*" work?)
OK, I fixed the regex, it needed a "non capturing group" around authors|work
2025-11-12 31643, 2025
ApeKattQuest
the A is for A at the end of the entity
2025-11-12 31648, 2025
monkey[m]
openlibrary\.org\/(?:authors|works)\/(OL\d+?A)
2025-11-12 31658, 2025
ApeKattQuest
what does non capturing mean?
2025-11-12 31616, 2025
ApeKattQuest
i need to learn regex properly orz

ApeKattQuest: See in the top right "explanation" panel, it explains each token:
2025-11-12 31647, 2025
monkey[m]
`\d matches a digit (equivalent to [0-9])`
2025-11-12 31647, 2025
monkey[m]
`+? matches the previous token between one and unlimited times,`
2025-11-12 31659, 2025
ApeKattQuest
what aprt of the regex makes it ignore the bit after the OL2165055A bit?
2025-11-12 31620, 2025
ApeKattQuest
I'll look at this now
2025-11-12 31639, 2025
ApeKattQuest
so this will let me test regular expresions so i cna make thme work before pasting? oohh neat

a capturing group means at the end you extract whatever is in the capturing group (in our case we ahe the OL ID captured).
2025-11-12 31602, 2025
monkey[m]
A non capturing group allows you to say, in this case, it should be one of "authors" or "works", but don't extract that value cause I'm not interested in it
2025-11-12 31648, 2025
ApeKattQuest
aha, since we already spesify it in the display template
2025-11-12 31611, 2025
monkey[m]
ApeKattQuest: Basically, the regex extracts what matches the capturing group, doesn't capture the rest
2025-11-12 31644, 2025
ApeKattQuest
why does "works" work tho ?
2025-11-12 31602, 2025
ApeKattQuest
oh becasue it was second?
2025-11-12 31613, 2025

openlibrary\.org\/works|authors\/(OL\d+?A) seems to work on authors but not works
2025-11-12 31639, 2025
monkey[m]
Because of the construction of the regex, it can translate as: either match "openlibrary\.org\/authors" OR match "works\/(OL\d+?A)"
2025-11-12 31603, 2025
ApeKattQuest
yes, that's what I wanted
2025-11-12 31616, 2025
monkey[m]
Adding the non-capturing group ensure the "OR" part only applies to "authors" or "works"
2025-11-12 31625, 2025
ApeKattQuest
oh!
2025-11-12 31634, 2025
ApeKattQuest
so not "author or works or OL### or
2025-11-12 31636, 2025
monkey[m]
You got it ? Difference is subtle
2025-11-12 31615, 2025
ApeKattQuest
so a non apturing grou is (?:foobar|foobas) and a capturing group is (blup|blup)
2025-11-12 31619, 2025
monkey[m]
What you wanted is either match "openlibrary.org/authors/OL.....A" OR match "openlibrary.org/works/OL.....A"
2025-11-12 31655, 2025
monkey[m]
ApeKattQuest: Almost, the bar in the middle is not part of the concept of groups, that's the "OR" part
2025-11-12 31605, 2025
ApeKattQuest
yea
2025-11-12 31623, 2025
ApeKattQuest
whats the sign for *and*
2025-11-12 31638, 2025
monkey[m]
But "(?:something)" will match but not capture "something", while "(something)" will match and capture "something"
2025-11-12 31654, 2025
ApeKattQuest
nothing this!
2025-11-12 31600, 2025
ApeKattQuest
noteing*

There is also a "Quick reference" panel on the right at the bottom which is absolutely necessary for people like me who use regexp once in a while and not everyday
2025-11-12 31612, 2025
monkey[m]
Let me tell you, learning regexps is a journey...
2025-11-12 31628, 2025
ApeKattQuest
lol

But you feel powerful once you manage to craft the esoteric incantation that does the magic you wanted it to do

thanks for this site I'll test regexes here before employing in the future
