Nemokosch umm, for the weekly challenge... 12:12
> Given a number base, derive the largest perfect square with no repeated digits and return it as a string. (For base>10, use ‘A’..‘Z’.)
are we expected to find fast enough solutions for large bases? the possible values grow exponentially 12:13
if you take the square root of a 36-digit number, that's still a humonguous 18-digit number 12:14

andinus can i make cro respond to both 'page' and 'page/' ? 16:45

leont andinus: generally speaking, you do not want to do that. Any relative URL in such a page will point to a different location depending on the presence of the slash or not 18:47
[Coke] might be better to have a redirect. 18:48
leont Exactly, that's generally the better idea.
[Coke] then the final page will act consistently for relative urls
leont++
leont I'd personally make the slashless version canonical, but that's entirely personal taste. Either option is fine, just be consistent 18:49
Another problem with aliasing them is that it's cache unfriendly
Because as far as caches are concerned, they're different URLs 18:50
andinus ugexe: i see, ya that would work 18:51
Voldenet: iasked it in #cro, - the middleware solution - paste.debian.net/hidden/ff0cb0f2/
leont: i see, that makes sense, i'll setup a redirect then 18:53
19:02 jjido left
SmokeMachine I was wondering… would that be possible/make sense to @ sigiled arguments of functions become Tuple? 19:07
[Coke] I don't think you can change what the default @ means. 19:12
You could specifically type things Tuple if you wanted.
leont Is there a less annoying way to turn a number into a bigendian encoded Buf than «my $b = Buf.new; $b.write-uint16(0, 1234, BigEndian);» 19:16
It seems like that shouldn't take two statement
[Coke] ... Buf.new.writ.... 19:17
which isn't helpful, but is one statement. :)
leont write-* return Nil, so it's useless 19:18
[Coke] I don't think there's a shorter way, no
SmokeMachine We can change what’s the default smile… shouldn’t we be able to change the default class for a sigil? Making Tuple the default for @ on function args would make simple to people understanding this: stackoverflow.com/questions/707794...rs-are-not 19:29
lizmat SmokeMachine: there have been several problem solving issues about that already 19:31
Personally, I think we need to revisit the whole picture for either 6.e or 6.f 19:32
19:34 lizmat left 19:37 lichtkind__ left
SmokeMachine Agree… but if we are adding an “immutable list” in core, that would be a great chance “fix the inconsistency” 19:38

thundergnat I stumbled across (typoed actually,) a bit of syntax I never saw before and was more than a little surprised it gave the answer I was looking for. 20:06

thundergnat I don't believe I have ever seen .$ as an alias for $_ before.
I assume I shouldn't rely on it... Or have I just been blind and never noticed before that was legal? 20:08
Voldenet bisect: for 1..5 { say .$ } 20:11

thundergnat Kind of a weird Easter egg rather than legal syntax I guess.
Voldenet m: for 1..5 { say $_.Any } 20:16
camelia No such method 'Any' for invocant of type 'Int'. Did you mean 'any'?
in block <unit> at <tmp> line 1
Voldenet most puzzling, I'm sure it's because `$` is Any 20:17

21:54 younder joined
younder I have problems with Compress:Zlib. I have a file in iso-latin1 and when it encounters a 8 bit character it goes into a infinate loop. 21:58
I eventually gave up copied the file and unzipped it in the local directory. 21:59
anyhow: 22:01

22:02 MasterDuke joined
younder "$line.encode("utf8").bytes == $line.chars" was needed to to filer ascii from iso-latin1 22:05
That took a lot of time to figure out.. 22:06
s/filer/filter/ 22:08
Anyhow what is the story of 'leave' not implemented yet. Would be more belivable if it didn't work :) 22:14
22:15 Garbanzo_ left
younder As i see it C(continue, break) -> raku(next, leave) 22:17
MasterDuke last is break
moon-child leave, not last?
leave is return from blocks, I think, and still nyi 22:18
younder That explains a lot.. 22:19
I thoght leave was like a goto where you jumped out of blocks except that you spesify the exit symbol before the nested loop rather than after. So leave without a symbol would be exit just the innermost loop. 22:24
guifa it's most commonly used in subs as a sort of cleanup-ish thing 22:25
younder yes. 22:26
guifa m: sub calculate-something { LEAVE say 'finished calculations'; return 'here are calculations' }; calculate-something()
camelia finished calculations
moon-child well no leave is different from LEAVE 22:27
younder of cource you have lEAVE to that or try {} CATCH {}.. there are many ways to do things
yes, the all caps versions confused me. What is the difference? 22:28
LEAVE { 22:30
        close $file;
  }
moon-child LEAVE is a phaser. leave is a not-yet-implemented directive which is similar to return except that it escapes blocks rather than subroutines 22:31
younder I sort of got that from working with the code. 22:33
Sorry to trouble you with a beginner like me, but the raku-beginner has practically no attendants. 22:35
22:37 jjido left
younder Why do you call it a phaser? 22:38
moon-child I don't know why they're called that. But see docs.raku.org/language/phasers 22:39
22:39 xinming left 22:41 xinming joined
younder So raku has no character type, just string?  I needed a 'for $word.split('', :skip-empty) -> $ch {' .. to itterate over characters. 22:45
and a integer.chr returns a string 22:46
moon-child do you perhaps want comb? 22:47
m: .say for "quux".comb
camelia q
u
u
x
younder perhaps like a 'go' rune..
moon-child 'rune' is not well-defined given unicode 22:48
younder nor is character
moon-child yes
(or, rather, it is well-defined but not to anything interesting)
again: comb probably does what you want here
younder Yes from the doc comb seems what I was after. thanks! 22:50
Is comb more efficent than .split('', :skip-empty)? 22:52
22:52 xinming left, xinming joined
moon-child seems so 22:53
I would not worry too much about it though
younder replaced it and it works.. 22:55
MasterDuke on a 50k line file, i get ~0.34s for comb()ing every line and ~0.45s for split()ting every line 22:57
22:58 SqrtNegInf joined
younder Another thing I miss Python's 'x in [array] is there a better way than 'grep { $ch eq $_ }, @guessed'? 23:06
moon-child x (elem) array or x ∊ array
younder thanks 23:07
23:08 xinming left 23:09 xinming joined
younder  '$ch (elem) @guessed' works.. 23:12
Well I have learned a lot. Thanks for your time. 23:13

elcaro .tell younder Phasers are contructs than can "fire" (get triggered) outside of the standard flow control. The ALLCAPS are to make them stand out because of this 23:49
tellable6 elcaro, I'll pass your message to younder
elcaro .tell younder eg. and INIT block at the bottom of your script doesn't happen last... or you could have a single CATCH block handle _all_ exceptions in a script. 23:50
