Kaiepi jesus i didn't notice how bad the boilerplate in my bot was until i shortened ~200 lines of code to this hastebin.com/legawomoqu.pl 00:58
01:00 mcmillhj left
Zoffix Doesn't that code have a data race? You're pushing to @lines from two separate threads. 01:00
I think a Channel is better for that (since it protects for such cases)
Kaiepi hm
depends, is any of rakudo's build scripts concurrent? 01:01
wait i think the tests are
Zoffix No idea, but does it matter? If either prints to both to STDERR and STDOUT, they don't need to be concurrent 01:02
01:02 zachk left
Kaiepi probbaly not 01:02
01:03 telnet is now known as tel, tel is now known as telnet
Kaiepi oh good channels work roughly the same as golang channels 01:05
AlexDaniel just use react maybe?
01:05 pharv left
AlexDaniel then you can just push into arrays just fine 01:05
01:06 pharv joined
AlexDaniel also .stdout.tap does not tap on lines 01:06
Zoffix What does it tap on?
AlexDaniel chunks
Zoffix Of what size?
And how to control them
?
AlexDaniel dunno to both, but you can use .stdout.lines to get lines 01:07
Kaiepi it taps each 80 characters from what i've seen
01:08 mcmillhj joined
Kaiepi lines would be better though 01:08
AlexDaniel Kaiepi: maybe see this as a reference: github.com/perl6/whateverable/blob...#L224-L268
Kaiepi ohhh 01:09
Zoffix This gives 20030 consistently with and without atomicint: gist.github.com/zoffixznet/ad3f569...baab369ed5
Kaiepi see i've read the docs for react, but i still didn't understand how it works
Zoffix So maybe there isn't a race.
Also, don't get where the extra 30 come from :S 01:10
I guess the chunking
yeah, doing stdout.line gives 20000 exact
01:10 elcaro[m] joined, pharv left
AlexDaniel Zoffix: try perl5 maybe 01:10
it could be that perl6 process is printing just too slow? 01:11
AlexDaniel tries himself
Kaiepi wait does react work sort of like select in golang? 01:12
except not specific to channels
01:13 mcmillhj left
AlexDaniel Zoffix: haha yea seems to be different with perl5 01:13
wait… 01:15
nah that's something else
I had this gist.github.com/AlexDaniel/6ce255c...bf3eadbddf 01:16
which outputs different numbers
but I guess for a different reason
Zoffix That's the chunking
.tell pmurias did some initial debugging for JVM issue, but giving up. Maybe it'll help you fix the problem: github.com/rakudo/rakudo/issues/17...-383771805 01:18
yoleaux Zoffix: I'll pass your message to pmurias.
AlexDaniel anyway, I don't know why it works, but it shouldn't 01:19
Zoffix What is? 01:20
AlexDaniel pushing to the same array from two taps
Zoffix Well, I'm guessing the two taps are fed from one event loop so it's just one thread actually or something? 01:21
Because it's one proc async
01:22 mcmillhj joined
AlexDaniel yeah, looks so 01:22
Zoffix or maybe not... sticking a `sleep` in one doesn't block the other
Zoffix doesn't know much about this stuff
AlexDaniel at least according to “say $*THREAD”
Zoffix or it's the affinity worker.... 01:24
Yup: *** Error in `/home/zoffix/rakudo/install/bin/moar': double free or corruption (!prev): 0x00007f87d86955c0 *** 01:25
Kaiepi: yeah, it's not thread safe.
AlexDaniel Zoffix: how did you get it to do that?
Zoffix If you stick ` sleep 2` into one of the code blocks, a second affinity worker will spawn and it'll be two threads. So the number of used threads depends on how busy the system is. The supervisor checks every 100ms (or 10ms) to see if it needs to spawn more workers and that sleep forces it to spawn 01:26
Kaiepi damn
01:26 mcmillhj left
Kaiepi i tried with channels but $c.list hanged regardless of if the channel was closed or not 01:27
AlexDaniel just use react, it's easier 01:28
Zoffix Kaiepi: react version: gist.github.com/zoffixznet/cb002b0...ad9057c094
This one is safe, 'cause only one whenever is run at a time. It also gives you better error reporting when stuff explodes
Kaiepi how does react decide which whenever statement to run? 01:29
that's what confuses me about it 01:30
Zoffix As for $c.list hanging... I'm guessing you forgot to .close the Channel 01:31
Kaiepi: it's asynchronous. So it runs whenever the event occurs
AlexDaniel well, if it's running something else already 01:32
01:32 rjt_pl left
AlexDaniel not* 01:32
Zoffix yeah
01:32 rjt_pl joined
Zoffix it queues it up to run, I guess I should say 01:32
Kaiepi ohh
AlexDaniel so it's doing synchronous processing of asynchronous events, sorta :) 01:33
Kaiepi zoffix i closed the channel before doing .list
Zoffix m: my Channel $c .= new; $c.send: "meows"; $c.send: "foos"; $c.send: 42; $c.close; say $c.list
camelia (meows foos 42)
Kaiepi i checked Channel.pm6 and it's trying to use .Seq on itself, but it doesn't seem to have a Seq method in it or its roles...?
ok weird 01:34
Zoffix s: Channel.new, 'Seq', \()
SourceBaby Zoffix, Sauce is at github.com/rakudo/rakudo/blob/a138...ny.pm6#L73
Zoffix It's provided by Any
Kaiepi oh
perlawhirl m: say (^10).head('5')
camelia This type cannot unbox to a native integer: P6opaque, Str
in block <unit> at <tmp> line 1
perlawhirl should .head be Cool ?
be Cool, man
Zoffix I really wish we establish a language-wide policy on such thing rather than fixing things piece-meal 01:35
m: say substr "abc", "1", "2"
camelia bc
Zoffix like here it works. There it don't
.splice used to coerce, now it doesn't.
01:35 timotimo left
AlexDaniel Zoffix: any downsides to coercing everywhere? 01:37
Zoffix m: say substr "abc", ("maybe",), <there are>
camelia bc
01:38 mcmillhj joined
perlawhirl maybe a good rule might be, if the argument can only ever be an Int, then it should be Cool (whether or not that criteria should be wider than Int is up for discussion) 01:38
Zoffix AlexDaniel: also, either slower speed or larger size with all the multies 01:39
m: say [].^lookup("splice").candidates.elems
camelia 31
Zoffix Like this would end up prolly around 50-60 candidates.
AlexDaniel puts his head in the sand 01:40
perlawhirl If I'm feeling bitter, I would say that making Lists Cool feels like it was something that was done to make the language more like perl5 that ended up being a mistake :S
Zoffix (and don't tell me the "torture the developer" stuff; there won't be any developers to torture when the code is an unmaintable pile)
Kaiepi zoffix: issue was i was closing the channel before awaiting the promise 01:41
instead of after
Zoffix ah
perlawhirl: in an alternate universe, there's a perlawhirl who's bitter because they have to stick explicit .elems all over the place :) 01:42
AlexDaniel just a prefix +
01:42 mcmillhj left
Zoffix You'll get 1 01:42
But it's not Cool anymore. It doesn't know how to behave like a number anymore. 01:43
Kaiepi btw thanks for the help
AlexDaniel :'(
right
Zoffix Well, I guess you won't get one either, because I was thinking you'd get a 1-el list :)
m: say +class {}.new
camelia Cannot resolve caller Numeric(<anon|1>: ); none of these signatures match:
(Mu:U \v: *%_)
in block <unit> at <tmp> line 1
Zoffix you'd get that :D
AlexDaniel
.oO( all universes suck )
 01:44
TEttinger I gotta say, I've been in here for a while now and I still have no understanding of the names Perl6 uses for almost anything
Zoffix Like what?
TEttinger Cool
01:44 eliasr left
Zoffix It's "Convenient OO Loop" 01:44
Also a pun.
TEttinger it's like there's a rule that unless it's an inside joke it can't be made permanent 01:45
Zoffix Like MoarVM is "Metamodel On A Runtime"
AlexDaniel
.oO( Strinty? Numstry? )
 01:46
01:46 ilbot3 left
TEttinger I still don't know what Cool is or does by the name or acronym 01:46
Zoffix Well, the first sentence of the docs answers precisely that :) 01:47
TEttinger I mean I'm not using perl6 any time soon, but I just want the channel to know that it sounds like you're all having strokes
Zoffix Erm. Thanks? :) 01:48
perlawhirl Zoffix: actually, I often perfer to use .elems because it conveys intent a little better then the short prefixes... but regardless, I suspect i'm bitter in all universes :D 01:49
01:50 AlexDaniel left
Zoffix perlawhirl: doesn't that argumentation defeat your original proposal to coerce things? :) Just use `say (^10).head: $x.Int`... conveys intent a little beter :D 01:51
perlawhirl I'm a walking contradiction
Zoffix perlawhirl: also, currently you don't need short prefixes. An array coerces to numeric automagically. It's Cool like that :)
Zoffix &
01:51 Zoffix left
perlawhirl TEttinger: Cool just means it can will coerce to string or a number depending on the context 01:54
AlexDaniel` TEttinger:
oops
perlawhirl m: my @l = < one two three >; say @l + 1; say @l ~ ' four';
camelia 4
one two three four
AlexDaniel` anyway, hey, we got rid of the texas thingy
and also we no longer use `nom` branch :)
there's also much less of “RT” which most newcomers know nothing about 01:55
TEttinger perlawhirl: what does the first say do there?
01:56 mcmillhj joined
TEttinger it looks like it prints the number 4? 01:56
01:56 ilbot3 joined, ChanServ sets mode: +v ilbot3
perlawhirl TEttinger: The use of the '+' infix means _numeric_ addition, so the list is coerced to it's number of elements (ie. 3) 01:56
AlexDaniel` yeah, number of elements + 1
perlawhirl so it's doing 3 + 4
01:56 AlexDaniel joined
perlawhirl i mean ... 3 + 1 01:56
m: say ('alpha', 'beta', 'gamma') + 1 01:57
camelia 4
TEttinger so... ~ is string concatenation but ~~ is smart match?
perlawhirl Yes
AlexDaniel and there's also ≅ :) 01:58
for approximate equality, but no ≈
TEttinger ≝ 02:00
02:00 mcmillhj left
AlexDaniel that's a cool character 02:01
perlawhirl TEttinger: It's mainly nice for checking number of elems in conditions, eg. if @things < 5 { ... }
similar to addition '<' means numerically less than, so arguments are coerced to numbers if possible 02:02
TEttinger mmm 02:04
02:04 vcv_ left 02:06 Herby_ joined
Herby_ o/ 02:06
\o 02:07
TEttinger I dunno. as I've gotten more opinionated on programming, I've found implicit behavior to be counterproductive even if it saves some keystrokes. having to consult a manual and hoping it adequately describes some corner case that's causing me issues takes a lot more time than typing out what I mean 02:08
a friend hit a worst-case scenario for this in Go, recently 02:09
golang.org/pkg/net/url/#URL.Parse was failing to fail on a clearly-invalid URL, the string containing only the ASCII char 127 (a control char, often DEL in older encodings) 02:12
going through comments in the code he found that it had been changed to address a Git issue. that issue cross-referenced the actual issue, which was that it was broken in the first release, was fixed but that broke code that expected the parser to be incorrect, so they had to un-fix the correct code for compatibility 02:13
02:14 mcmillhj joined
perlawhirl yeah I tend to agree on the opinionated thing most of the time, which is why i'll typically write `@things.elems` 02:18
02:19 mcmillhj left
perlawhirl but i constantly appreciate that i can treat the string '10' as a number in perl if i want to 02:19
particualy when translating things to other languages, and realising to make calls to `int()` in a bunch of places 02:20
so I'm not against Cool in principal... but making Lists Cool is the source of quite a few traps that I'd happy do without 02:21
happily*

AlexDaniel implicit behavior being that lists turn into the number of elements in numeric contexts? 02:49
02:50 espadrine_ left, mcmillhj left 02:57 mcmillhj joined 03:02 mcmillhj left
MasterDuke i think List.contains is a trap (implicit behavior being it stringifies the list) 03:03
lookatme good noon 03:05
m: say (1, 2, 3, ).contains(1) 03:06
camelia True
lookatme m: say (1, 2, 3, ).contains(12) 03:07
camelia False
lookatme m: say (1, 2, 3, ).contains("1, ") 03:08
camelia False
lookatme m: say (1, 2, 3, ).Str 03:09
camelia 1 2 3
lookatme m: say (1, 2, 3, ).contains("1 2 ")
camelia True
Herby_ rookie question: does declaring types for functions and objects typically provide a speedup compared to not declaring them?
sub triple-number(Int $x) {} versus triple-number($x) {} 03:10
03:16 mcmillhj joined
MasterDuke Herby_: right now there's usually not much of a speedup for using high-level types (e.g., Int, Str). however, native types (e.g., int, str) are frequently faster (assuming of course it's correct to use them in the given situation) 03:16
m: my Int $s; for ^1_000_000 { $s += $_ }; say $s; say now - INIT now 03:17
camelia 499999500000
0.8544502
MasterDuke m: my int $s; for ^1_000_000 -> int $_ { $s += $_ }; say $s; say now - INIT now 03:18
camelia 499999500000
0.5473163
Herby_ ahh ok
Looking here: docs.perl6.org/type.html, I see Int, int, and Str but I don't see str 03:19
MasterDuke that may be deliberate, i don't think str is as different from Str as int is from Int 03:21

ufobat_ is there a difference between --> and returns for signatures? I wanted to put a function signature in a pod C<...> but that would not work with --> 06:46
06:50 wamba left
jmerelo ufobat_: that should work in Pods. Maybe escaping? 06:57
ufobat_: and yes, there are differences between --> and returns docs.perl6.org/type/Signature#inde...turn_Types 06:58
ufobat_ docs.perl6.org/language/functions#...onstraints dosn't mention that there is any difference 07:00
07:00 mcmillhj joined
ufobat_ maybe there should just be once place in the documentation which covers this topic? 07:01
jmerelo ufobat_: Yep, maybe. Main differences is that returns will probably be obsoleted and it does not work with constant values (verbatim from above)
ufobat_ i am reading through it :) 07:02

ufobat_ if --> is the way to go, and the pod documentation doesn't mention how to quote the > in C<...> it might be not possible 07:03
jmerelo ufobat_: but maybe we should say "different and not equivalent" instead of "many" ways.
ufobat_ ack! 07:04
jmerelo ufobat_: yep, that's the other end of your question. I can't say off the top of my head. Either escaping or equivalent unicode char or quoting should work... But would have to check it out. 07:05
ufobat_: maybe ask in StackOverflow? ;-)
07:06 mcmillhj left
ufobat_ hah! 07:06

jmerelo ufobat_: have you tried it? It seems to work, although in a weird way... 07:13
ufobat_ tried what?
i just wrote the stackoverflow question
moritz you can use C<< stuff with --> in it >>
ufobat_ moritz, what about writing a stack overflow answer :p 07:14
jmerelo ufobat_: thanks!
moritz done 07:15
ufobat_ \o/

moritz stackoverflow.com/questions/499954...d/49995512 for the record 07:21
El_Che ufobat_: I remember a discussion inclusing TimToady. He liked the '-->' (I like the returns) 07:22
07:22 wamba joined
moritz same here :-) 07:22
but --> has some advantages (like, it's obviously part of the signature)
also, people seem to downvote stackoverflow.com/a/49892419/14132 and I have no idea why
ufobat_ is "is export" part of the signature, technically?
El_Che there was an advantage I forgot. It was a really good point. 07:23
moritz ufobat_: no
El_Che: the other is about scoping
($x, $y --> returns $x * $y) { # side effect here }
argl
($x, $y --> $x * $y) { # side effect here }
(I don't think that's implemented yet)

I haven't debugged cores since the 90s. Pretty much around the time I started to use Perl.
jnthn Using NativeCall successfully pretty much means knowing at least something about C programming. 09:37
moritz and C is simply too untyped for most kinds of automated checks 09:38
09:38 mcmillhj joined
jmerelo jnthn: but it's not too obvious that to get a CPointer you just need to instantiate a CSstruct. 09:38
jnthn It's not actually Rakudo that dumps core, it's the C code you called dumping core because you called it wrong.
jmerelo jnthn: Yep, I know. Maybe it should be the "Rather unforgiving nature of the C code called from NativeCode", but it didn't have the same ring to it. 09:39
09:39 scimon joined
jnthn "How to correctly call clock_gettime with NativeCall" would have been even better ;-) 09:40
jmerelo jnthn: stackoverflow.com/questions/499975...-interface 09:41
jnthn: way I see it, the main problem is that I'm using a CPointer instead of a CStruct. But, in fact, clock_gettime uses a pointer to a struct linux.die.net/man/3/clock_gettime 09:43
09:43 zakharyas joined
jnthn jmerelo: A CStruct instance is already implicitly a pointer to a struct though 09:44
jmerelo jnthn: in fact, you are also creating a new instance, which I don't, but it coredumps all the same if I keep using CPointer and I try to instantiate it.
jnthn: OK, I need to document that, then. Then what's the use case for CPointer? 09:45
jnthn CPointer is when you just want an opaque pointer to something
But don't have any data stored within it
It should probably complain if you declare something with CPointer and it has attributes
jmerelo jnthn: as in void*
09:45 mcmillhj left
jmerelo jnthn: a complain by NativeCall would have made it less unforgiving. 09:45
jnthn Yeah, file an issue about that 09:46
void* - well, maybe, but it's more useful when the C library does all of the memory allocation itself and you don't ever need to look inside of the structure.
You just need to receive and pass the pointer 09:47

jmerelo jnthn: done github.com/rakudo/rakudo/issues/1767 09:52
There are apparently no uses of CPPStruct "in the wild" 10:07
Only one I've found is github.com/FROGGS/p6-Box2D/tree/fc...1f9424e7/t by FROGGS but it's not too clear to me how it's actually loading the library. 10:08
10:12 Actualeyes left
jmerelo I find also curious the use of native(Str) for functions already loaded. It does not seem to work with native(Mu) or native(Cool). Anyone knows why? 10:15

jmerelo p6: use NativeCall; sub getppid(--> long) is native(RatStr) {*}; say getppid;
camelia 811
jmerelo He
jnthn Just because it's type-constrained to accept some subtype of Str there 10:20
jmerelo p6: use NativeCall; sub getppid(--> long) is native(Stringy) {*}; say getppid;
camelia 5===SORRY!5=== Error while compiling <tmp>
No appropriate parametric role variant available for 'NativeCall::Native'
at <tmp>:1
jnthn At a C level it'll be mapped into a NULL argument to loadlib (or dlsym, forget off hand) 10:21
jmerelo jnthn: yep, I imagined as much. But I don't really get the rationale after using Str and not Any or Mu. Or the empty string.
p6: use NativeCall; sub getppid(--> long) is native {*}; say getppid;
camelia 811
jmerelo OK, it can use the empty string.
jnthn Right, that's the neater way :)
Empty string is a bit too likely to be an accident rather than intended 10:22
jmerelo Is this the code? github.com/rakudo/rakudo/blob/b07e...ll.pm6#L69
If you change that to "Mu" will it break everything asunder? 10:23
jnthn No
(as in, no, that's not the right place)
Why do you want to change it? Just use the `is native` form without an arg :)
jmerelo jnthn: not really. I just want to know the rationale after using precisely Str and not Mu or just leave it empty. 10:24
jnthn I suspect it may almsot be an accident that Str means that 10:26
*almost
jmerelo jnthn: probably so :-) 10:27
OK, since I got that figured out, thanks to jnthn, next question is: Is there any CPPStruct ready to use without compiling an external C++ program? 10:29
As in, some part of the POSIX interface that's actually written in C++, or part of MoarVM, or Rakudo, or anything in general.
I suspect not, since the rakudo tests actually have to compile an external library, but just in case. 10:30
10:30 markong joined, timo joined, timo is now known as Guest8740 10:31 Guest8740 is now known as timotimo
jmerelo jmerelo: maybe I should put this in some other way. Is there any way of knowing what's readily available from the is native(Str) interface in the form of callable functions or (C|CPP) structs? 10:32
Maybe I should go to StackOverflow for that?
.tell jmerelo you definitely should
yoleaux jmerelo: Talking to yourself is the first sign of madness.
jkramer Is there are a way to make s/// return the modified value instead of modifying the lhv in place? Like s///r in P5? 10:33
Or any other way to do .subst(' ', '', :g), but shorter? :) 10:34
jnthn (S:g/' '// given $var) 10:35
jmerelo: Not sure you'll find any CPP structs. I guess the various things from libc and other posix-y things can be relied on if you're on such a platform. 10:36
jmerelo jnthn: OK, created the question anyway stackoverflow.com/questions/499995...rom-the-na 10:38
jkramer What's uppercase S? Can't find it on docs.perl6.org/language/regexes
moritz return the string with the substitutions, instead of modify-in-place 10:39
jmerelo jnthn: but, theoretically, you can access more layers than just posix, right? At least MoarVM and Rakudo, although this last one is probably not very native. 10:40
jnthn You could I guess find MoarVM functions, yeah
jmerelo And MoarVM is actually written in C, right?
jnthn Rakudo is written in Perl 6, not C, so you won't find its internals that way :)
Yes, MoarVM is C
timotimo finding the functions inside moarvm for its internals will do you little good unless you also find where the MVMInstance lives :P 10:41
or one of the MVMThreadContexts
well, i suppose a pointer to one of those will usually be on the stack 10:42
jnthn But you could create an instance ;-)
jmerelo timotimo: and they will be available as VMStruct, right?
jnthn MoarVM in MoarVM :)
timotimo what's a VMStruct? 10:43
jmerelo timotimo: nothing. I seemed to remember there was something like that in the NativeCall interface. 10:44
jkramer moritz: I thought so, what I meant was: where's the documentation? :)
jmerelo jkramer: please create an issue. I haven't been able to find the documentation either. 10:45
jkramer jmerelo: Will do 10:46
jmerelo timotimo: repr('VMArray'), that's what I remembered... there is no repr('VMstruct') (I guess)
10:48 Zoffix joined
jmerelo jnthn: there are a bunch of NativeCall::Compiler classes, most of which include CPPStructs. Could that be used? 10:48
jkramer: thanks.
Zoffix jkramer: docs.perl6.org/language/operators#...bstitution 10:49

timotimo: but there's a VMArray... 10:51
jnthn jmerelo: Used for what exactly? 10:52
jkramer Zoffix: Ah, too late, already created the ticket :)

timotimo yeah, VMArrays are very different from CArrays. what's the problem? 11:02
i see no reason to patch gcc, clang, and MSVC just so we can invent a VMStruct thing for moarvm 11:03
jnthn VMArray is just the representation of a resizable array provided by the VM 11:07
It's best treated as an implementation detail
I'd especialy treat types like utf8 being based on VMArray as an implementation detail

moritz Lisp is homoiconic, but Ruby and Perl 6 are not. In this regard, Perl 6 is closer to Ruby 20:14
comborico1611 timotimo: Thanks! 20:15

comborico1611 Is a "sequence" what Lisp calls a "list"? 20:16
moritz a sequence is closer to an iterator 20:17
comborico1611 Is there anything closer to a Lisp list than sequences in Perl6?
timotimo lisp lists are only cons cells, right? 20:18
no, wait, that was haskell
comborico1611 Correct, to the best of my newb knowledge.
moritz List is closer
comborico1611 moritz: Thanks!

comborico1611 The main reason I came back to Perl6 over Common Lisp was readability via concise-ness. 20:23
What is returned when you use substr beyond bounds? 20:28
The REPL just did a blank nothing. Is that undefined? 20:29
timotimo m: say "foo bar".substr(100, 1) 20:30
camelia Start argument to substr out of range. Is: 100, should be in 0..7; use *-100 if you want to index relative to the end

timotimo m: say "foo bar".substr(1, 100)
camelia oo bar
timotimo m: say "foo bar".substr(7, 100)
camelia
timotimo m: say "foo bar".substr(8, 100)

timotimo m: say "foo bar".substr(8, 100).^name
camelia Failure
timotimo ok, so it's a lazy exception
comborico1611 m: my $dream = "I have a dream"; say $dream.substr(14); 20:33
camelia
comborico1611 m: my $dream = "I have a dream"; say $dream.substr(15);
camelia Start argument to substr out of range. Is: 15, should be in 0..14; use *-15 if you want to index relative to the end

comborico1611 [14] is newline? Hmm. 20:34
timotimo no, the newline comes from the say sub
say puts a newline after everything
comborico1611 So why no error on [14]?
timotimo because it's still in the string
just at the very end 20:35
comborico1611 What is it?
m: my $dream = "I have a dream"; $dream.chars;
camelia ( no output )
moritz m: my $dream = "I have a dream"; say $dream.chars;
camelia 14
comborico1611 Is [14] nil? 20:36
timotimo how do you mean?
20:36 zakharyas left 20:37 pharv left
comborico1611 m: my $deam = "I have a dream"; say $dream.substr(14).WHAT; 20:37
camelia 5===SORRY!5=== Error while compiling <tmp>
Variable '$dream' is not declared. Did you mean '$deam'?
at <tmp>:1
------> 3my $deam = "I have a dream"; say 7⏏5$dream.substr(14).WHAT;
comborico1611 I'm just confused that there are only 13 characters in that string, but the system says there is 14.
timotimo how do you get that impression? 20:38
20:38 pharv joined
comborico1611 I just hand counted. There are 14 chars, but the last one is a space or something. 20:39
mcmillhj_ I'm a little confused about Hash#push. my %h; %h.push('a' => 'b'); # works %h.push(c => 'd'); # doesn't work
^ why is the quoting required here?
timotimo no, there are exactly 14 chars in that text, only three of those are spaces 20:40
mcmillhj_: a pair with an autoquoted key in a parameter list will be taken as a named argument, which Hash#push doesn't do anything with
if you want, you can add a second set of parenthesis, then you don't have to quote inside 20:41
mcmillhj_ hmm okay, is that related to the method signature of Hash#push? Or does that apply generally to all parameter lists? 20:42
20:43 pharv left
timotimo it applies to all parameter lists, it's just that methods by default have a slurpy hash parameter so you won't get an error if you add named arguments it doesn't expect 20:43
mcmillhj_ I also see this syntax in the docs my %h; $h.push: (a => 'b'); # works
Ugh, just noticed this in the docs: "Please note that Pairs or colon pairs as arguments to push will be treated as extra named arguments and as such wont end up the Hash. The same applies to the sub push.". Sorry for the un-needed question :) 20:44
timotimo no problem 20:45
20:46 pharv joined
mcmillhj_ well actually, what does the colon do exactly? Just used to disambiguate? 20:46
20:47 pharv left, pharv_ joined
timotimo well, a sub call without parenthesis is a statement prefix which will gobble the rest of the line up if it can, but method calls without parenthesis are very common (because attribute accesses are method calls, too) so if you want them as statementlist prefix you have to put something, and that something is the colon 20:48
tobs comborico1611: when you substr at index 0, you can read a string of up to 14 chars. When you start at index 14, you can read a substring of 0 chars, which is what you get.
comborico1611 How can you read no character? 20:50
mcmillhj_ timotimo: I understood some of that :) but I take it to mean it is an alternative syntax with which you can call a method. Is that an accurate summary?
timotimo yeah, that's fair 20:52
comborico1611 is topical variable ($_) always associated with "for"? 20:53
moritz no
mcmillhj_ timotimo: cool, thanks for the help !
comborico1611 Thanks!
Kaiepi when should you use latin1 instead of utf8-c8 with encodings for nativecall? 20:57
20:57 zacts joined
Kaiepi with one library i know to use utf8-c8 since it changes the locale to utf8, but what about those that don't? 20:58
timotimo depends entirely on what you want to do with the data 21:00
comborico1611 m: for "25-12-2016".split("-") -> $bob; say $bob; 21:02
camelia 5===SORRY!5=== Error while compiling <tmp>

comborico1611 What are the braces doing?
21:03 |oLa| joined
comborico1611 Is there an alternative synatax? 21:03
timotimo they are the block part of the pointy block that you started with ->
comborico1611 Ah, hence the name. I was wondering why it was called a block 21:04
timotimo yes, you can use postfix-for, i.e. say $_ for "25-12-2016".split("-")
block is a kind of code
comborico1611 So every use of -> requires { } ?
timotimo off-hand i can't think of one that doesn't 21:05
comborico1611 (In the context of pointy-blocks, not including other uses.)
I see. Thanks. I'm just trying to get a feel of how things are.
Kaiepi wdym timotimo
can you give some examples? 21:06
AlexDaniel well, sometimes you can get away with WhateverCode
not with for though, but in other cases
m: say <1 5 8 2 3 4>.grep: { $_ < 3 }
camelia (1 2)
AlexDaniel m: say <1 5 8 2 3 4>.grep: * < 3 21:07
camelia (1 2)
comborico1611 I see.
AlexDaniel m: say <1 5 8 2 3 4>.grep: -> $x { $x < 3 }
camelia (1 2)
timotimo Kaiepi: if you don't care about treating it as text, use latin1
m: say "☺".encode("utf8").decode("latin1")
camelia Can not decode a utf-8 buffer as if it were latin1
in block <unit> at <tmp> line 1
timotimo m: say "☺".encode("utf8").list.Buf.decode("latin1")
camelia No such method 'Buf' for invocant of type 'List'
in block <unit> at <tmp> line 1
timotimo m: say Buf.new("☺".encode("utf8").list).decode("latin1") 21:08
camelia âº
timotimo if it's okay with you to get this kind of string from that kind of input, use latin1
Kaiepi ah
so when would latin1 be appropriate to use? 21:09
timotimo when you only want to shove data from one piece of code to another without even something simple like counting how many characters are in it
comborico1611 .say for split ", ", "Jan, Feb, Mar" # Is .say shorthand for something else here? What is long version? 21:10
evalable6 Jan
Feb
Mar
timotimo $_.say is the long version 21:11
comborico1611 Thanks!
Kaiepi so i'm guessing it's not very useful
comborico1611 Danggit. It was the next line in teh book...
Man, this chapter on Strings is super dense. 21:12
timotimo another reason to have latin1 is when you absolutely don't want it to error out when data doesn't look like correct utf8
i'm not sure if utf8-c8 still complains about unicode codepoints outside the valid range 21:13
21:13 mcmillhj_ left
Kaiepi it doesn't 21:14
i think
m: "\x1FFFF".encode('utf8-c8') 21:15
camelia ( no output )
Kaiepi m: dd "\x1FFFF".encode('utf8-c8')
camelia Blob[uint8].new(240,159,191,191)

camelia utf8.new(240,159,191,191)
Kaiepi wait 21:16
hold on lemme find one of the astral codepoints
m: dd "\xDC80".encode('utf8') 21:18
camelia Error encoding UTF-8 string: could not encode Unicode Surrogate codepoint 56448 (0xDC80)

Kaiepi oh wait i know how to test this properly 21:20
timotimo that's the wrong way around :)
moritz m: say Buf.new(0xDC, 0x80).decode('latin1')
camelia Ü
Kaiepi hm maybe i don't 21:26
only way i've had encoding errors happen is screwing up with nativecall

AlexDaniel m: say 'äbcdefghijklmnöpqrstüvwxyz'.ords».chr
camelia (ä b c d e f g h i j k l m n ö p q r s t ü v w x y z)
timotimo be advised that .ords gives you the base ords for every character 22:04
so if you have something very combined, pieces will get lost
Kaiepi so i'd have to use .codes?
timotimo more likely .NFD or .NFC
AlexDaniel Kaiepi: ok well, what are you trying to do in the first place? Why do you need codepoints?
Kaiepi i don't :^) 22:05
timotimo getting at the codepoints under a string is not as easy as getting at the graphemes for a reason: you'll shoot yourself in the foot
Kaiepi i was just curious
for what i'm doing i'm only dealing with ascii
AlexDaniel Kaiepi: so typically .comb will do what you want, yeah
especially if it's ascii-only 22:06

23:15 mcmillhj joined
