rypervenche Is it possible to pull two values out of a hash at once? I'm currently pulling one out with: @data»<date> . Is there some way to do this without needing to use @data twice? 00:59
oh 01:00
I just figured it out. Just do @data»<date day-of-week>

rypervenche Although it's returning an array of arrays and I'd like it to be an array of strings. I'll have to figure out how to change it. 01:38

guifa how are you making it? It should provide a list of the hash values 01:49

camelia (List)
rypervenche No, I think it's normal. I'm doing this from an array of hashes. 01:57
I guess I'll have to do something like two for loops to change the inner arrays into strings.
guifa Don’t forget about the hyper operator, it can be useful at times for that 02:05

rypervenche I may be doing this all wrong, but yeah. Trying to sort by date and also have the day-of-week available for printing in sorted order.
Ahhhh, good ol' map always doing what I need.
guifa I don’t know the whole of what you’re doing, but you can sort on just a key. 02:11

rypervenche I'm trying to count how many of each date and then print the date and day-of-week along with that number. I was thinking of throwing that string in a bag and then maniulating the string afterward to get the right order of text. 02:14

camelia TrueTrue
lizmat Voldenet: in other words, let subs a and b eat all extra nameds
Voldenet: if this is about using subs in a class, then maybe making them private methods would be clearer ? 17:52
Voldenet that looks a lot better, thanks 17:59
and no, they're not methods in the class, it's a whole mess of a script at the moment :D 18:00
I wonder…
m: sub a(:$x, :$y, |) { say $x, $y }; sub b(:$z, :$r, |) { say $z, $r }; sub c(|e) { a(|e); b(|e) }; c(:x, :y, :z)
camelia TrueTrue
Voldenet ha, obviously
lizmat that would also eat additional positionals, which you probably don't want ?
Voldenet I don't mind - all subs take named arguments 18:02
lizmat which means you would like to be informed at compilation that you mistyped ":$a" by forgetting the ":" ? 18:03
.oO( been there, done that :-)
18:05 kensanata left
Voldenet I shouldn't have written so many arguments to subs in the first place and should've used a few configuration classes in the first place 18:08

(just asking - it's possible to convert most of things into json anyway) 18:19

[Coke] I've been happy with macports, if you want a second opinion. 23:27

cfa fwiw, i also like macports but have nothing against homebrew 23:48
also, afternoon all 23:49
tbrowder supposedly with homebrew i can get the gnu tools with same behavior as on linux as opposed to rhe bsd-like in normal osx 23:51
cfa tbrowder: coretools, gmake etc? 23:52
tbrowder that's what i think they advertise
i'll check more closely. i got the advert for them when i was looking foe emacs on mac... 23:54
my son is giving me an old mac mini i plan to use with a large screen tv, and do a little rakuing with it on the side ;-) 23:55
vrurg tbrowder: if memory serves me right, homebrew has much lesser number of ports. 23:56
23:56 titsuki joined
tbrowder ah, that may be a deal breaker... 23:57
cfa the supposed advantage of homebrew over macports is that it leverages a lot of system-installed libraries
whereas macports tends to build its own, which in some cases are duplicates
the advantage is that everything is consistent and sandboxed
tbrowder ok, thnx, i guess it will be a new learning experience. so macports are from bsd people? 23:59
