librasteve o/ hi! 09:16
my regex brain is fading ... I have this rx / <[A..Za..z]> && <[0..9]> / to check that a str has at least one digit and one letter... but it fails I guess since the conjunction && requires a substring to match BOTH the first and second criteria ... can anyone show me how to do this within a regex? 09:18
nahita3882 hi, i think doing this within a regex involves lookaheads/behinds etc. and gets tedious if not worse in performance 09:29
compared to doing two regexes and &&'ing their results
coranila @librasteve: regex are linear unless you introduce lookaround or backreferences; as such you probaby want "a letter followed by a number or a number followed by a letter", as in /[ <[A..za..z]> .* <[0..9]> ] || [<[0..9]> .* <{A..Za..z]>/ or /<alpha><?before <digit>>||<digit><?before <alpha>>/ 09:41
lizmat m: say so"fo1".contains(/ <[A..Za..z]> / & / <[0..9]> /) 09:42
camelia True
lizmat I think that actually reads better as well
coranila yes but that's the "cheat" of using two regexes - which i do agree is probably appropriate, but still is a bit of cheat in that it does reframe the problem somewhat - of course, in the interest of clarity this is totally approppriate here! 09:43
.oO( too many words for "i agree" :-) ) 09:44

librasteve thanks to all… it certainly reads better … this is the test for a Cro::WebApp::Form is validated trait, so hopefully I can jam multiple regex into the API 10:59
the api takes the thing and applies as the rhs of a ~~ smartmatch will report back later when back in the keys 11:01
feels a junction coming on 11:13

lizmat: that works well... 12:22

timo if you want a && to ensure both a letter and a digit, you can most easily .* before and after it I think 14:37
m: for <abc 987 ab1cd2ef abcd1 1abcd 11a33> { say $_, " matched? ", so m/ .* <[a..z A..Z]> .* && .* <[0..9]> / } 14:43
camelia abc matched? False
987 matched? False
ab1cd2ef matched? True
abcd1 matched? True
1abcd matched? False
11a33 matched? True		 14:44

Guest35 what is the keyword that says stop scanning the source code? 15:43
jdv exit? 15:46
lizmat =finish
jdv hmm, is there something like __DATA__ in raku? 15:49
i feel like i used to know this
lizmat $=finish
everything after =finish 15:50
jdv but is that a fh?
or stream or whatever
lizmat it's a string
m: say $=finish.^name
camelia Mu
lizmat meh
m: say $=finish␤=finish␤foo 15:51
camelia foo
lizmat m: say $=finish.^name␤=finish␤foo
camelia Str

jdv ugexe: nevermind. odd that the dir listing looks the same for all but "inst#" prefix is needed for the "non-regular" one 19:31

tbrowder my wife’s macbook wants to upgrade from Sonoma to Sequoia, any reason not to? 20:13
tellable6 2025-04-24T23:02:54Z #raku <wayland> tbrowder: This is why I've wrapped my github tests in a docker container, so that I can run the container on local when debugging these problems.
tbrowder wayland: sounds like a good idea, but i just tried reading github’s logs again and it wasn’t too bad. i think when the test’s do fail, their short msg seems not to be very helpful. 20:17
re macbook, only 8 GB ram, is that enough for the upgrade? 20:19
