Set by moritz on 22 December 2015.
timotimo moritz: seems like the server i was ircing from until now has gone belly-up. i think i might want to move over to irc.p6c.org, but i don't think i have an account there; could you make one for me with the same authorized_keys as on hack? 01:02
timotimo also, i wonder why the weechat version on hack is 1.0.1 when there's already one with a much higher version number available 01:05
there have been 7 releases since 1.0.1, the latest of which was on the 2nd of october: version 1.6 01:06
timotimo - remove "freenode" server from default config - :\ 01:09
timotimo seems like the server's back 01:12
MasterDuke timotimo: would you know anything about this nqp-j error: "Flattening named argument must have VMHash REPR"? 01:16
timotimo hm, are you calling |%foo with something that's actually NQPMu? 01:18
MasterDuke it's happening somewhere in tools/build/install-core-dist.pl, during make install 01:19
timotimo hm, so it's actually perl6-j?
it could help if you'd output the actual REPR that you get for this error message
MasterDuke yeah, but the error is in nqp/src/vm/jvm/runtime/org/perl6/nqp/runtime/CallSiteDescriptor.java
i added a .getClass().getName(), it was '__P6opaque__74' 01:20
timotimo is that how we get the debugname of things on the jvm?
MasterDuke no idea
timotimo i'd have expected something more helpful there
timotimo that script i was running in the background is now at 167 megabytes (35 minutes of cpu time on the main thread) 01:21
Herby__ if i'm on Windows, and wanting to do some basic HTML parsing, is there a recommended module?
or am I destined to use regex?
i browsed through the module library but didnt see anything that stood out 01:22
timotimo there's modules for you
i think HTML::Parser::XML isn't bad. Gumbo isn't bad either.
Herby__ my eyes passed right over HTML::Parser::XML, let me give it a whirl 01:23
Herby__ couple of basic basic questions incoming... 01:44
following the last example here (github.com/tony-o/perl6-html-parser-xml), I now have an xmldoc 01:45
Herby__ how do I print that out in a coherent manner so I can see what my data looks like? 01:45

dataf4l hey guys 05:34
I just have a quick question
dataf4l I generated a moar file using perl6 —target=mbc —output=mine.mbc mine.p6 05:35
after generating the file, I’d like to run the mbc file wihout the p6 file
you know, for science
I have no idea on how to do that, and I feel the docs aren’t clear.
timotimo at the moment, you have to pretend it's a module and run an empty script
dataf4l any pointers?
timotimo perl6 -Mmine -e '' 05:36
dataf4l so run an empty p6 file and use the -m option?
let me try
timotimo at least it was like that the last time i looked ... last year maybe?
dataf4l Felipes-MacBook-Pro:backend2 a$ perl -Mguess.mbc -e "" 05:37
syntax error at -e line 0, near "use guess."
my codeI’m afraid your suggestion was not effective, but in any case I’d like to give you thanks, I feel you tried to help, and I value that a lot. 05:38
timotimo no, not "guess.mbc"
dataf4l perl6 --target=mbc --output=guess.mbc guess.p6 05:39
what is the correct extension for mbc target?
timotimo -M is equivalent to a use statement; you don't put filename extensios into use statements
dataf4l so a pm then?
timotimo well, then it'll use a precompilation repository for you 05:40
oh, and also the extension it'll look for is .moar, not .mbc 05:41
dataf4l what the expletiv is a precompilation repository! if you pardon my ignorance
ok I’ll try moar
timotimo actually, i can't get it to load the .moar file locally 05:42
if you -Ilib for example, rakudo-moar will create a .precomp folder in lib/ and .moar files go there
dataf4l -llib at the compilation step? 05:43
I’m trying this: 05:44
perl6 -I. -Mguess -e ""
===SORRY!===

whoops, now he's gone
timotimo hey dataf4l 05:57
dataf4l hi
timotimo it'll want to find a guess.pm6 if you -Mguess
dataf4l ok
I have a .moar file
no idea on how to load that one
timotimo well, in theory moar eats moar files
so just "moar guess.moar" 05:58
but i don't think it'll actually do what you want
dataf4l Felipes-MacBook-Pro:backend2 a$ moar guess.moarvm 05:58

p3rln00b kinda annoying
I guess it's some composing thing that's causing this and it ain't a bug :} 13:00
jnthn "It's complicated" 13:04
p3rln00b :D
jnthn So roles are generic and parametric
jnthn And thus a "does Foo" is not in general resolvable until we are actually finally composing into the target class 13:05
The solution we take for classes is to put of attribute decl checks until after roles are composed
So we know what we've got and what, if anything, is missing
jnthn *put off 13:06
That's rather harder for roles themselves though
p3rln00b I see.
DrForr Well, there's some activity here now; I'll toss this out to the channel. 13:09
I got an email last night from brian d foy asking me if I'd like to co-author Learning Perl 6.
p3rln00b Does brian d foy even use Perl 6? Never seen him here 13:10
iH2O he should, using it is adopting it 13:11
DrForr He's getting more interested in it, certainly. Plus you don't have to be on this channel in order to use perl6 :)
p3rln00b still remembers being chasticed by bdfoy over a module name
iH2O not sure, esp if u a beginner 13:12
jnthn Not everyone does IRC :)
iH2O they do facebook?
reddit?
DrForr Uh, he wrote "Learning Perl" :) I don't think he needs help with presence :) 13:13
iH2O this room is a must to produce intricate regex expressions 13:15
on one line
p3rln00b Well, I guess that was one of my points. Is he writing Learning Perl 6 because he likes the language and knows a lot about it or just because he wrote Learning Perl and knows people will buy Learning Perl 6 just 'cause it got his name on it :)
DrForr It can't be both? 13:16
iH2O theres a shortage of good up-to-date perl6 book anyway 13:17
*books
im not sure theres any
DrForr Shortage as in "there are none." (not counting Laurent's work, as it's still being reviewed.)
iH2O :(
p3rln00b DrForr: So was there more to bdfoy asked you to write a book? Or is that the entire news item? :)
DrForr No, asked if I'd like to join him. That's ... pretty much it. Sorry you're underwhelmed. 13:18
moritz and Laurent's book is Learning to think likea programmer, using Perl 6 to teach that
it's not about teaching Perl 6
so for an experienced programmer, it's probably a bit long-winded
p3rln00b DrForr: heh. Well, it's just I already found that out yesterday, so yeah... underwheliming :) 13:19
DrForr: did you tell him you'd love to join him?
DrForr Yes, I do know I've mentioned it elsewhere.
Well, of course. Why wouldn't I?
p3rln00b :)
moritz \o/ 13:20
the more books, the merrier
iH2O theres none for now
DrForr We talked about this in person a few months back when he was in Cluj. 13:21
p3rln00b DrForr: when will the book be finished? 13:24
I recall Damian also promising a book "in a year" when he was in Toronto a few months ago
DrForr No idea; he's the one working on financing. All I really know is he's interested in doing the book and is setting up a Kickstarter project and looking at funding. 13:25
p3rln00b cool 13:26
perlpilot_ DrForr: nice! Would merlyn be coauthor too or just you and bdf? 13:29
DrForr I don't know whom else he's talked to, but either way I'm happy to share credits. 13:30
DrForr Basically he's wanting to kick around some ideas, so I'm going to take some time this weekend to brainstorm some notions and send them his way. 13:31

samcv nice
p3rln00b samcv: using $.irc ... um... it's a bit more involved, since the client is multi-server. You need to know what server to ask for channels for. 14:27
p3rln00b glances at the docs
samcv yeah
p3rln00b samcv: you can just use the variable and tell the client to join channels in that variable and loop over that same variable: gist.github.com/zoffixznet/213f910...e-p6-p6-L6 14:28
samcv ah ok i thought about doing that 14:28
p3rln00b samcv: this is a "proper" way to loop over all connected servers and channels: github.com/zoffixznet/perl6-IRC-Cl....p6#L7-L15 14:29
There's a blog post for that module FWIW: perl6.party/post/IRC-Client-Perl-6-...IRC-Module
samcv yeah it's a good post 14:30
oh did not see that part
p3rln00b The guy who wrote it is a genius.
samcv , we loop over all of the connected channels and use $.irc.send method to send a message to that particular channel and server, unless the server and channel are the same as where the message originated.
p3rln00b I want him to have my babies :}
samcv it's a lot better than perl5's BasicBot :P 14:31
i hate that thing
i mean it's not 'that' bad. but
it's nowhere as good as IRC::Client
p3rln00b samcv: ah, right. That's just for the forwarder. For yours, you'd just get rid of this line to send to *all* channels: github.com/zoffixznet/perl6-IRC-Cl...rder.p6#L9

samcv i want a perl6 book :( i wish there was one 15:14
someday
p3rln00b Why do people want books so badly? :) 15:15
iH2O the official documentation is deficient
samcv because i wanna read
p3rln00b deficient! Bah
iH2O for beginners, or intermediate users its deficient 15:15
samcv documentation is documentation :)
mst p3rln00b: because you didn't figure out how to script conversion of docs.perl6.org to an ebook instead
samcv yeah what iH2O
if you already know perl6 you can see the docs and say, yes that is true and correctly documented
iH2O i agree 100% 15:16
samcv otherwise you're like but. what does that mean for me as a programmer :)
p3rln00b mst: actually we have. gfldex++ made it generate one giant HTML file that can be converted to an ebook :P
mst p3rln00b: WHY IS THERE NOT A LINK TO THAT ON THE FRONT PAGE
p3rln00b mst: dunno. I personally found it a bit unmanagable.
p3rln00b It's like 500 pages long 15:17
samcv link to it anyway :P
will be good to ctrl + f it
mst that would've been fine. I read through all the individual pages, one at a time, in pubs
some of them had medicore wifi
samcv googling perl6 "$!" turns up nothing because google ignores it :) found what it is, for attributes on the perl6 sigil page
mst so I'd have to stand up, walk to the other side of the room where the signal was better, load the next three pages, then go back to my beer
samcv but doesn't talk all that much about it
mst an ebook would have removed this impediment to my alcohol consumption 15:18
p3rln00b I think this is it:
docs.perl6.org/perl6.xhtml
DrForr duckduckgo is better about the "special" variables.
samcv nice
sometimes *_* sometimes not
mst p3rln00b: yeah, I meant an ebook conversion of it
chrome would've lost my place I'm sure
samcv i will sell you that printed out for 50 dollars
p3rln00b there's probably html2epub somewhere 15:19
samcv it would look bad tho
p3rln00b If not, print as HTML and I know calibri can convert to epub from pdf
*print as PDF
samcv wew
duckduckgo $! perl6 and
stockflare.com/stocks/$perl6 get this page
for stocks of perl6 15:20
p3rln00b Considering duckduckgo has special bells and whistles for Perl 5 and Python docs, I'm sure they would be open to add same feature for Perl 6 :)
mst p3rln00b: waah. the point I'm making is a conversion on the front page would be nice.
p3rln00b mst: wasn't it you who were telling tbrowder awhile back that when someone says "would be nice" it means they want someone else to do it? :P 15:21
p3rln00b You got a commit bit, don't you? :) 15:21
mst p3rln00b: I believe I was talking about "should"
p3rln00b Ah, right.
mst I use "would be nice" specifically to avoid that effect 15:22
p3rln00b samcv: as for the book. I know currently of two that are in production, with a third one that was kinda-sorta "promised" to be done "in a year" a few month ago. 15:22
mst cuz what I'm saying is "I haven't written a patch that, but currently you're being so dismissive of the idea I don't see why I'd bother"
Xliff_ zoffix: Nice blog post on IRC::Client
samcv p3rln00b, please send me the proof copies :P 15:23
mst also, honestly, also "I'm lazy, riba's insane, and I need to cpan my ::EU stuff more than I need to fix this"
p3rln00b samcv: as for the docs. You would be in the best position to improve them. Those who know Perl 6 well can fill in the missing pieces and it's hard to know which stuff is missing. 15:23
mst: I didn't mean to be dismissive. 15:24
samcv i am glad to help howerever i can
p3rln00b samcv: what's the email address? I can sub you to a mailing list that should be put up soon. For the other book, ask DrForr
samcv ok
sent pm
p3rln00b got it.
FROGGS o/ 15:25
DrForr For the other book I don't know much more than bdf right now. 15:25
samcv oh btw p3rln00b the sigil page should have a link to docs.perl6.org/language/objects.html#Attributes
when it talks about the $! sigil
mst samcv: github.com/perl6/doc/issues/
samcv: please throw problems you spot into there
samcv oo ok. just open an issue?
ok :)
that makes me happy 15:26
p3rln00b samcv: better yet, submit a PR
mst samcv: yeah. I opened them at quite a rate as I was working through the docs and people were happy about that
but I was usually going "I don't know what the right thing is, but I think this is wrong"
samcv who was usually right? 15:31
mst I'm sorry? 15:32
there were quite a few people who figured out the various fixes and tweaks and etc. for those
p3rln00b Oh crap. 15:33
p3rln00b just did a "It's a small fix. Push it to production because testing is a pain"
And now I broke something :P Lesson: Always test on dev server first 15:34
mst p3rln00b: the only time it's valid not to is if production is already down 15:39

p3rln00b That paste looks really messed up. Are you using tabs for indentation? :) 15:54
moritz seems like you use $!proc outside of a method
p3rln00b One too many braces.
samcv ok i fixed the problem by fixing the braces. yes i am
there were two actually
moritz which happens if you close too many parenthesis before using it, for example 15:55
samcv no my braces were just all messed up in reality p3rln00b
p3rln00b Ah yeah
moritz fix that first
no wonder you're losing overview
p3rln00b samcv: really? Weird. When I paste from that pastebin to Atom, it shows all the braces aligned just fine.
Well, other than the two extra ones :)
samcv well they are aligned 'fine'
but not correctly
so maybe it did mess it up
yeah i copied in stuff without tabs in it 15:56
geekosaur atom likely treatng hard tabs as 4 spaces, pastebin as the usual-for-unixes 8
samcv yeah that messes things up
well the browser does that geekosaur
it just has the literal tab character on the page
moritz method irc-connected ends before the "await .start" line
which is likely not what you want
moritz so, too many closing curlies 15:56
samcv usually it converts them when i paste things it but i guess it didn't work this time. yeah moritz it was not good 15:57
geekosaur yes. technically it's the browser rendering. you still won't find anything to tell every browser everywhere to render them as 4 spaces; they always use 8
samcv yeah
geekosaur (and if there were one it'd be different for every freaking browser /o\ )
p3rln00b Clearly the correct answer is to use spaces for indent :P 16:01
samcv in python 3 i hear you can't even use tabs for indent 16:02
idk i use tabs for indenting code blocks and spaces for aligning things to the current block 16:03
say what you will!
maybe i'm totally insane :)
mst samcv: tabs for indentation and spaces for aligment is actually the objectively superior system in theorty 16:04
samcv yeah
mst however, in practice it seems to involve dipping your genitals into a bag of rusty razor blades
samcv hahah 16:05
pmurias having tools to take care of indenting code seems more important then the exact details of the way used 16:07
mst my main reason for using spaces is that I hate every re-indenter I've ever worked with 16:09
so I'd rather do everything the hard way, because at least then it does what I expect 16:10
jonadab Tabs for indentation work in word processing, when you want to indent by some number of inches while using a proportional font. Though even there, setting paragraph indent is usually better. 16:26
Tabs in source code are evil and must be destroyed. 16:27
p3rln00b :D
mspo mm tabs 16:32
mspo I think .eu prefers tabs but .us tends to prefer spaces 16:32
.uk indents in something called "whitz" ;) 16:33
jonadab Tabs don't work for indenting source because A) nobody can agree how wide they are and B) no matter what width you say they are, it's wrong for a lot of use cases and C) the correct level of indentation relative to the line above will not always be a multiple of any number higher than 1 in the first place. 16:36
p3rln00b fight fight! 16:37
jonadab You can make it work for stuff like indenting the body of a loop, but it falls over very badly when you have things like conditions wrapping onto more than one line.
p3rln00b Well, for all of those points there's an equal number of counterpoints :) 16:41
The Tabs vs. Spaces is the biggest bikeshed of the galaxy.

well, if the tabs would remain in the source file, you'd have a proper encoding of your intent in the file
geekosaur but that's exactly the problem. tabs are not semantic markup 16:54
p3rln00b My intent is to indent, not to insert tabs
geekosaur people want them to be, but they aren't
geekosaur nor can you somehow combine them with spaces so you get both the semantic markup and the physical representation that compilers and editors insist on using 16:55

harmil_wk Using the parameter-type-conversion syntax (A(B) $c) with MAIN seems to not work. Is this how I should have expected it to work? gist.github.com/ajs/80ceb7fe672cfe...40ecf93e69 18:35
p3rln00b harmil_wk: what does "not work" mean? 18:36
geekosaur I think that's known and expected because anything handed to MAIN is intrinsically string-y 18:36
timotimo right, you get IntStr and such there 18:37
harmil_wk p3rln00b: It fails to convert from Str, and just gives usage
timotimo those will already match Int and Str 18:38
well, did you give Str a .Filename method?
harmil_wk geekosaur: But Foo(Str) :$foo should take a Str and ugprade it shouldn't it? 18:39
geekosaur as timotimo said, only if there is a coercer already

p3rln00b harmil_wk: ^ that's your problem. I guess sub MAIN just doesn't actually throw that error and instead prints usage
geekosaur yes, I think it catches exceptions and prints usage instead 18:40

harmil_wk Is it? That's not what that syntax is supposed to be
geekosaur [13 18:39:45] <geekosaur> you can't tell it "coerce these" unless it knows how to coerce, which means a .Filename method in Str 18:41
p3rln00b harmil_wk: syntax for what?
harmil_wk Hold up... I'm confused. So, if I want to have a type that can be coerced to from Str, I have to monkey-patch Str to know about it? Isn't that backwards? 18:42
timotimo it's sub-optimal, but all solutions to this particular problem are 18:43
geekosaur what timotimo just said
p3rln00b harmil_wk: but how else would a type know how to coerce to your custom type?
timotimo subs are lexical, for example, so the knowledge of how to coerce would be limited to where you're calling from
timotimo AFK 18:44
harmil_wk p3rln00b: I don't think that's what anyone should want. What we should want is to have my custom type know how to coerce FROM a given type. That's what I assumed the A(B) $c signature syntax was doing...
If my custom type can be coerced to from Int, Str, Complex and IO, I don't think that it makes sense to go modifying all of those, does it? 18:45
p3rln00b harmil_wk: Feels dirty. You're not coercing anthing "from". You're proposing a mechanism that would set attributes or create a new object when a particular routine is called. 18:46
harmil_wk Well, coercing is, of course, creating a new object. It's not polymorphism. 18:47
p3rln00b Which I'm pretty can be done with a subset anyway
harmil_wk how?

bioduds_ hi, friends. 19:19
Anyone interested in mining bitcoins using Perl6??? 19:20
arnsholt Note that there's a difference between -> {} and sub {} in how return works 19:21
cygx m: sub coerce(Any:U \Type, \obj) { my $m; $m = obj.can(Type.^name).first(*.cando(\(obj))); return $m(obj) if $m; $m = Type.can("new").first(*.cando(\(Type, obj))); return $m(Type, obj) if $m; obj }; class Foo { method new(Int) { self.bless } }; sub foo($x is copy where { $x = coerce Foo, $x }) { say $x }; foo 42 19:22
camelia rakudo-moar bf7945: OUTPUT«Foo.new␤»
arnsholt m: sub foo($x) { $x(); return 42 }; say foo(-> { return 1 }) 19:23

bioduds_ I'm asking because of what Damian Conway raises in prospect of cryptography breaking capabilities with Perl6 on this talk here www.youtube.com/watch?v=Nq2HkAYbG5o
bioduds_ made me wonder... 19:23
bstamour you would still need a quantum computer to break the crypto in a reasonable amount of time 19:24
maybe we can start porting perl 6 to the d-wave?
p3rln00b bioduds_: you weren't paying attention to that talk. At one point he does say there's no hardware currently in existence for his quantum stuff code to actually do it
(or at least did in person; I attented the "longer version" of that talk; didn't watch the vid :P) 19:25
bioduds_ p3rln00b : oh, okeydokey. thanks a lot :) 19:26
what is d-wave?
p3rln00b bioduds_: and aren't bitcoins minded with purpose-made hardware these days anyway? And isn't bitcoin dead 'cause they reached the limit or whatever the hell happened last year there? :)
bioduds_: en.wikipedia.org/wiki/D-Wave_Systems 19:27
moritz bitcoins are mined with ASICs, yes
bioduds_ blockchain is real, I guess even though I don't really know the status of bitcoins in that matter
p3rln00b "128-qubit superconducting adiabatic quantum optimization processor"... oh, that sounds so sexy
moritz there are other coins with algorithms designed to not be easily approachable with specialized hardware
moritz p3rln00b: to me, "adiabatic" means "boring" :-) 19:28
bstamour p3rln00b: I don't even know what half those words mean, but I want one :-)
bioduds_ adiabatic is a gaseous transformation if I recall correctly from physics classes
p3rln00b doesn't know what adiabatic is so it sounds exciting :D
bioduds_ that happens very fast 19:29
for instance, spraying out some substance makes the can become cool
due to adiabatic transformation, again, if I correctly recall it 19:30
moritz it just means that no heat exchange happens at the system border
bstamour They forgot to mention "mutilating your privacy" on their Applications page 19:30
bioduds_ p3rln00b : please clarify me on that 'whatever happened', I didn't follow this 19:33
geekosaur there is an upper limit to the number of transactions representable on the blockchain 19:34
although I didn't think they had hit it yet, not that I pay that close attention
bioduds_ so basically what you're saying is that a blockchain is limited to a number of transactions? 19:35
p3rln00b bioduds_: I don't remember. One of the founders or someone "up there" with the bitcoin wrote a blog post that they reached the limit or something. All I recall is a giant blog post with a ton of charts and everyone on the net saying it's the end of bitcoin
bioduds_ therefore, making it impractical? 19:36
mst no 19:39
bioduds_: if you google 'bitcoin block size problem' you will find out all about it 19:40
bioduds_ doing right now :)
bioduds_ seems like mining is dead for mere mortals 19:48
samcv nice i'm on freen 20:04
oops sorry wrong room
ugh goddam popups
bioduds_ and looks like the network is "irrecuperably" jammed
thanks for the insight, gentlemen :) 20:05
stmuk_ damm! missed a talk this evening by Sophie Wilson (ARM designer) due to dental issue 20:07
I bet it was good
probably similar to www.youtube.com/watch?v=b5j_Y-ML3dg 20:10
timotimo nothing better than watching a movie over SMB with a network cable that's missing its clip 21:31
when the laptop lies on the floor and the cat keeps walking against the cable
Technaton Just walking against, or playing with it? :) 21:34
AlexDaniel gfldex: hmmm… what about changing all of your answers to community wiki? (re: SO and its crap) 21:48
perlawhirl hi AlexDaniel 21:49
AlexDaniel not sure if it is possible, but sounds like an interesting idea
perlawhirl: hi
perlawhirl i'm not sure why that happens irclog.perlgeek.de/perl6/2016-10-10#i_13374587
but i suspect... the & forces function calling semantics 21:50
the .elems method parameter is an InterationBuffer... whatever that is ??
and the elems() function just takes a normal value
but i suspect before *.elems ever receives the arguments, it's being pushed though the function calling semantics of &() 21:51
so you end up with something akin to
m: say (<30 50 60>, <3 4 5 6>)».&elems
camelia rakudo-moar 7f16cb: OUTPUT«((1 1 1) (1 1 1 1))␤»
AlexDaniel m: say (<30 50 60>, <3 4 5 6>)».elems 21:52
camelia rakudo-moar 7f16cb: OUTPUT«(3 4)␤»
perlawhirl one of the core dev's could probably answer, but i suspect IterationBuffer is some special type that buffers the values until the iteration ends, which allows ».elems to work 21:53
I could be wrong about all this... I'm just guessing
again, tho... ».&(*.elems) is an x/y problem
AlexDaniel well, the biggest question right now is how do we document this 21:54
for example, I created this issue: github.com/perl6/doc/issues/960
but we can also improve this: docs.perl6.org/language/operators#...ix_%C2%BB.
perlawhirl i agree the docs for » are lacking. i think part of that improvemnt is documenting the purpose of constructs like '@args».&()' really do. 22:01
my gut says that '».&()' syntax is geared towards mapping a function (ie, in subroutine context) for _each_ of a list of args
'».method' may behave differently because mainly because those methods behave differently from their function equivalents
take 'join' for instance... the method has a default $separator, the function does not 22:03
m: say <a b c>».join
camelia rakudo-moar 7f16cb: OUTPUT«(a b c)␤»
perlawhirl m: say <a b c>».&join
camelia rakudo-moar 7f16cb: OUTPUT«( )␤»
perlawhirl the point is... not all functions act like there method brethren 22:04
timotimo perlawhirl: the reason why it's different is because *.elems doesn't keep the "is nodal" from its thingie 22:33
timotimo perlawhirl: with join, you're actually passing one letter as the separator in turn. but the list you're joining is empty, so you end up with three empty strings as the result 22:34
perlawhirl timotimo: yes, i figured out the join thing the other day, was just using it to illustrate the difference 22:44
timotimo ah 22:46
perlawhirl timotimo: so what does "is nodal" mean/do? 22:50
timotimo exactly the difference between giving you 1 1 1, 1 1 and 3, 2 22:53
perlawhirl so in context... '< a b c >' is a "node" ?
timotimo yeah 22:55
geekosaur more or less, "nodal" indicates whether something should descend into structures or not 22:56
perlawhirl can functions do "is nodal", or only methods ? 23:04
AlexDaniel m: sub foo is nodal {}; foo 23:15
camelia ( no output )
AlexDaniel huggable: dunno 23:16
huggable AlexDaniel, ¯\_(ツ)_/¯
perlawhirl AlexDaniel: in your case, my original comment stands. &() is a function, albeit an anonymous one 23:20
by the time that function recieves the arguments, it's not "nodal"
m: sub count { @_.elems }; say (<a b c>, <x y>).&count; say (<a b c>, <x y>)».&count
camelia rakudo-moar 7f16cb: OUTPUT«5␤((1 1 1) (1 1))␤»
perlawhirl ».&(*.elems) is the same as that last example ^^^ 23:21
