antononcube 🙂 thanks for pointing it out! 01:06
guifa I kinda wish there were an equivalent for <!> that failed the outer regex instead of just the current alternation 01:09
maybe <!!> ?
sort of like a "I'm intentionally taking you down a bad path so die plz" 01:10
antononcube @guifa Shouldn't this happen with fail and || ? 01:12
I.e. emulated... 01:13
guifa actually maybe it doesn't and I'm forgetting about backtracking

xinming hmm, I think I need to write the function myself, as they're not Set compare 08:08
nahita3882 are you looking for eqv 08:31
set equality comparator is (==) (or ≡) 08:32

xinming I used sub array-eq (@a, @b) { for @a Z @b -> ($a, $b) { $a == $b }; True } 10:05
nahita3882 that always returns True 10:06
SmokeMachine Why not using eqv? 10:11
m: sub array-eq(@a, @b) { [&&] @a Z[==] @b }; say array-eq [1,2,3], [1,2,3]; say array-eq [1,2,2], [1,4,3] 10:13
camelia True
False

xinming SmokeMachine: I'll use eqv, I just know eqv when I read doc, But don't know how to use that yet. 10:38
the [&&] @a Z[==] @b version is better 10:39

ab5tract Todd2: I think you aren’t in a repl 13:55
Todd2 I actually am 13:56
ab5tract Ah, ok. That’s not clear from the sequence you shared as raku -v doesn’t start one
Todd2 I was giving my revision number 13:57
ab5tract And the error message is a Windows (or maybe even DOS) one
nahita3882 that's exactly the error to get when executing $*OUT.encoding(:bin); $*OUT.write: chr(27) ~ ' Hi ' ~ chr(27) ~ '' on cmd.exe directly 13:58

Todd2 Now this is annoying, in Fedora Bash I get a green `HI`.   In Windows 11-24H2, I get `← HI ←`.   I can send the same command with "echo" and I get teh green HI. 14:08

[Coke] Todd2: I was the one responding via email; all the ANSI codes just work for me on the same version of raku - tried to sync up the module version and then went into a rabbit hole of not being able to compile on windows 11. 14:40
If you're having trouble with just emitting the direct codes, then it's not an issue with the module; guessing you have some OS issue that is not setup to enable the ANSI codes. 14:41

Xliff \o. Is there a way to tell if a Routine is marked "is rw"? 16:11
lizmat m: dd (sub a() { }).rw 16:23
camelia Bool::False
lizmat m: dd (sub a() is rw { }).rw
camelia Bool::True
lizmat Xliff: ^^
Xliff lizmat: Ah, thanks! I actually went trough the whole source tree and found it 5 minutes ago. LOL!
lizmat I guess that made 2 of us :-)
Xliff Buried in nqp of all things. Is this available in the docs? All of the $!flags should be documented there. 16:24
lizmat not sure 16:26
whether documented I mean
the reason it's buried in nqp, is because it's needed to build the proper QAST I guess
Xliff I would look myself, but I'm on the clock and have a meeting in 2 hours. 16:27
lizmat there's no hurry :-)
for looking that up, I mean :-)
