Dear Christian and BaseX friends, I hope this email finds you well! I had a question about function signatures:
it would seem that there's a typo/issue with the signature (and final example) for array:sort[1,2]. Shouldn't the signature for array:sort read: array:sort( $array as array(*), $collation as xs:string? := fn:default-collation(), $key as fn(item()*) as xs:anyAtomicType* := fn:data#1 ) as item()* (cribbed from the qt4cg.org specs[3])? Unless I'm misreading the signature... in which case, excuse me! Additionally, the current signature for array:sort seems to be in approximate alignment with array:sort-by, which is missing from our lovely BaseX docs' array page. To further my confusion, it looks like the examples from the qt4cg.org array:sort-by[4] signature work generally in my BaseX 12.0. Could that be added, or is the function still waiting in the BaseX wings? :) Best wishes, Bridger [1] https://docs.basex.org/main/Array_Functions#array:sort [2] the example `array:sort( [ 1, 2, 3 ], keys := fn($n) { -$n })` throws an error in BaseX 12.0: [XPST0017] array:sort(array[,collation,key]): Unknown keyword: keys. I'll update the example if I may please have access, otherwise, change `keys` to `key`, please.
