00:12 autarch could someone explain what this error means -
00:13 timotimo what kind of thing is Pod::TreeWalker?
00:13 autarch joined #perl6
00:13 timotimo what kind of thing is Pod::TreeWalker?
00:14 autarch timotimo:
00:14 autarch oops, wrong link -
00:14 timotimo does it contain other things? did use-ing the module it's in cause some mismerge to happen, so that Pod::TreeWalker is now only a module/package?
00:14 autarch it's "unit class Pod::TreeWalker;"
00:14 timotimo hum.
00:15 timotimo i don't know :(
00:15 autarch the tests for that module pass just fine
00:15 timotimo uh-oh
00:15 timotimo and the code you've written?
00:15 autarch but when I try to use the code via PERL6LIB I get that error - maybe that's helpful?
00:15 autarch except at least one thing which uses it via PERL6LIB _does_ work
00:15 timotimo does it work if you use -I instead of PERL6LIB?
00:16 * autarch checks
00:16 Hotkeys say a class has ::ver<1.2.3> tacked on it, is there a way to get the version?
00:16 autarch nope
00:19 micxjo joined #perl6
00:19 autarch I'll update to the latest HEAD just in case

00:22 roguelazer What's the correct way to install panda right now? `rakudobrew build-panda` seems to indicate some syntax issues with moar-2015.11
00:22 flussence m: class Ttt:ver<1.2.3> { }; say Ttt.^methods(:all).elems

00:23 autarch ok, still getting the same error with the latest rakudobrewed p6
00:23 autarch if someone could me figure this out, I'd appreciate it - it's the last thing I need to resolve before my advent calendar article is ready for review
00:29 flussence m: class Pod::TreeWalker { }; class Foo { has Pod::TreeWalker $w .= new() };
00:29 camelia rakudo-moar 97ef74: OUTPUT«===SORRY!===␤Could not locate compile-time value for symbol Pod::TreeWalker␤»
00:30 flussence maybe a symptom of that?
00:30 flussence (neither error makes sense to me, mind)
00:30 Psyche^_ joined #perl6
00:30 timotimo oh, probably because Pod:: is already in core?
00:30 timotimo m: say Pod::
00:30 camelia rakudo-moar 97ef74: OUTPUT«Pod␤»
00:30 flussence m: class Foobar::TreeWalker { }; class Foo { has Foobar::TreeWalker $w .= new() };
00:30 camelia rakudo-moar 97ef74: OUTPUT«===SORRY!===␤Could not locate compile-time value for symbol Foobar::TreeWalker␤»
00:31 timotimo um
00:31 timotimo wait, does .= work in that location?
00:31 timotimo m: class Pod::TreeWalker { }; class Foo { has Pod::TreeWalker $w = 1 };
00:31 camelia rakudo-moar 97ef74: ( no output )
00:31 flussence it ought to, but I'm just being lazy...
00:31 timotimo it does not
00:31 flussence m: class Foobar::TreeWalker { }; class Foo { has Foobar::TreeWalker $w = };
00:31 camelia rakudo-moar 97ef74: ( no output )
00:31 flussence guess I'm wrong
00:32 autarch this all started after I renamed the module from Pod::NodeWalker to Pod::TreeWalker
00:32 flussence m: class Foobar::TreeWalker { }; class Foobar::TreeWalker::SomethingElse { has Foobar::TreeWalker $w = };
00:32 camelia rakudo-moar 97ef74: ( no output )
00:33 autarch the weird thing is I have a branch of Pod::To::HTML that uses TreeWalker and it works fine -
00:33 timotimo hm, didn't masak just file a bug on RT about things going missing when ... something mumble mumble?
00:34 flussence you have a use; for it both inside and outside the class scope there, maybe that's why?
00:34 timotimo
00:35 autarch flussence: I removed the use inside the class scope and it's fine
00:37 autarch anyway, if someone could review my advent article, that'd be great - it's saved as a draft in the wordpress blog - day 11
00:38 MadcapJake is there any way to nuke panda?
00:38 flussence rm -r $install_prefix (or git clean -dfx if you used the default one)
00:39 flussence though that'll nuke rakudo too, which may be overkill
00:40 timotimo autarch: when will it go live?
00:40 timotimo oh
00:40 autarch timotimo: well, day 11, I'd assume ;)
00:40 timotimo 11
00:40 timotimo that's in a few days, not a few hours

00:46 csd_ joined #perl6
00:49 pippo joined #perl6
00:52 ShimmerFairy .tell masak I just had a thought about the ugly {{{}}} syntax: what about a vaguely Lisp-inspired `{} ? After all, the backtick is free in P6 :) . (Though I don't think it'd have quite the same meaning as `(), hence "vaguely inspired")
00:52 yoleaux ShimmerFairy: I'll pass your message to masak.
00:52 MadcapJake ok so my rakudo fork is looking in a completely different directory for modules than the rakudobrew-installed perl6
00:52 moei joined #perl6
00:53 ShimmerFairy did you use --prefix in your configuration, perchance? If not, that might explain it :)
00:53 MadcapJake i didn't even make install, can't you just work with it inside the src dir?
00:53 MadcapJake i don't want to install it anywhere in my usr dirs
00:54 Juerd Is it possible to have either lazy interpolation, or a custom quotelike operator/
00:54 MadcapJake ShimmerFairy: do you mean in the perl command?
00:54 ShimmerFairy yes
00:55 ShimmerFairy MadcapJake: btw, I think you do need to install it. Note that by default rakudo and friends install locally within the repo. I always configure MoarVM and the rest with --prefix=/usr/local  :)
00:56 ShimmerFairy MadcapJake: or maybe you don't have to. I'm not entirely sure.
00:57 Juerd OMG, I should dive into the source more often. Just discovered "ignoremark". I've seen recent commits from TimToady, but didn't know what it was about. But now I get it, and it's wonderful.
00:57 MadcapJake well everything works except for modules :P  it looks inside the source directory and the rakudobrew installed version looks inside `.rakudobrew/moar-nom/install/share/perl6/{site,vendor,.}`
00:58 Juerd m: say so "föó" ~~ /:m foo/
00:58 camelia rakudo-moar 97ef74: OUTPUT«True␤»
00:58 Juerd
00:58 ShimmerFairy MadcapJake: hm, it probably makes sense that it doesn't know about your weird rakudobrew directory :P  ("weird" as in "not some kind of universal system directory or something")
00:58 dy joined #perl6
00:59 MadcapJake ShimmerFairy: definitely would be a bizarre convention, however to me it seems more bizarre that there's no way to work on rakudo in isolation from your system.
01:00 MadcapJake I wish I could have a stable install and then leave the rakudo bleeding edge inside it's source dir
01:00 Hotkeys anyone know how I can get the version number of a class
01:00 Hotkeys without having a seperate variable for it ofc
01:00 ShimmerFairy MadcapJake: I'm not sure I follow; isn't the source version not using ~/.../rakudobrew/.../ accomplishing that "isolation from your system" ?
01:01 MadcapJake yes but then how can I use modules :(
01:01 Hotkeys since there is the :ver adverb
01:01 MadcapJake I thought maybe modules were separate from rakudo
01:01 MadcapJake but they seem tied to each version
01:02 ugexe yes, precompilation assures you it needs to be rebuilt for each version/change of the compiler
01:02 ShimmerFairy MadcapJake: ah, you'd maybe want -I or PERL6LIB in that case? I don't know how the new module system works, and it's worth pointing out precompilation _does_ tie the precomps to each version
01:02 ugexe although without precompilation you are right
01:02 ugexe at least right in that you can do it if you want
01:03 ShimmerFairy Hotkeys: based on my nearly-nonexistent understanding, that's probably not exposed yet. Unless the :ver adverb is explicitly mentioned in docs on the new module system, chances are that's specified by the META6.json instead
01:04 MadcapJake Ok I see that, so I concievably *could* keep it isolated by installed panda inside my rakudo fork's source dir?
01:04 Hotkeys I know it's in S11 and I've seen it used but I can't really find an other docs
01:04 MadcapJake is that possible?
01:05 PotatoGim joined #perl6
01:06 ShimmerFairy MadcapJake: I always have panda install to ~/.perl6, not sure if that info helps any (I don't know what it'd do if run with a non-[system-]installed p6)
01:06 csd_ joined #perl6
01:07 MadcapJake ok i'll explore that idea at least
01:08 ShimmerFairy MadcapJake: if nothing else, there's always manually using -I to point to git repos of the right modules (blech), or officially graduating to using just bleeding-edge rakudo all the time (I've done it for years!) :P
01:09 flussence if you're insane, you can also put the paths to everything you want in a meta6.json sitting in a directory on its own and -I that
01:10 MadcapJake where does panda install modules? in `.perl6/<rakudo_version>`
01:10 ShimmerFairy MadcapJake: but I will say that the idea of a version-independent collection of modules for developers sounds like a nice idea
01:11 Actualeyes joined #perl6
01:11 flussence MadcapJake: it did that for about a day and it made everyone unhappy, I think it puts modules there but binaries go in install_prefix
01:11 ShimmerFairy MadcapJake: For me, running  ./  after installing rakudo to /usr/local  will install to ~/.perl6. Presumably running the bootstrap under 'sudo' would use a system location
01:11 flussence yep, modules are there for me
01:12 flussence looks like %?RESOURCES go to install_prefix too, I see in it
01:15 * AlexDaniel wonders if anybody will ever merge tau tests :D
01:15 * MadcapJake is glad to see the rest got merged at least!

01:24 dj_goku or is looping through each one building a new hash the only way?
01:25 flussence crazy idea, may not actually work, maybe %h1.append(%h2)?
01:25 dj_goku oh append
01:25 flussence just a guess, like I say it might not be right
01:25 dj_goku oh oh
01:25 flussence if that fails, :{ |%h1, %h2 } ought to do the job

01:38 flussence if there's a short, readable way to .map on a hash's values and get a hash back... I don't know it.

01:41 flussence if you know exactly how long your input is, you *might* use grammars, if you don't, use regexes

01:42 dalek perl6-most-wanted: review:
01:42 ShimmerFairy Herby__: if your code starts to look like a massive tree of    if $a ~~ /.../ { if $a ~~ /..../ { ... } }    , chances are you want a grammar :)
01:43 Herby__ hmmm
01:43 ShimmerFairy Herby__: in the case of parsing a file, you'll probably want grammars. If nothing else, it'll organize the regexes nicely.
01:43 Herby__ My code does kind of look like that.
01:44 * flussence has that type of code in Text::Wrap and it's horrible, long overdue for a rewrite
01:44 flussence in a few places the *right* of the smartmatch is variable too...
01:44 ShimmerFairy I personally would suggest that the times you use grammars over inline /.../ regexes are about the same as the times you write an explicit function over using an inline -> { ... } closure :)

01:47 ShimmerFairy Herby__: another possible question is "would using <subrule>s in my parsing make things easier to write?" (you can write "local" rules, e.g.    my token foo { ... };    , as an intermediate sort of step between inline regexes and full grammars, if you like)
01:47 ShimmerFairy Herby__: I'm not aware of any speed difference, so chances are "not much" :)

01:48 dalek perl6-most-wanted: review:
01:48 flussence Grammars are slow. Painfully slow sometimes (which is why we have a gazillion JSON modules, and why building rakudo takes forever at "Stage parse"). But they're declarative syntax so you can write your code once and making it run fast becomes Someone Else's Problem :)
01:50 ShimmerFairy except for the procedural bits :)
01:52 MadcapJake if i cloned and installed a new rakudo and panda, why does it say there are modules already installed?
01:53 flussence if you didn't completely wipe the install directory, they're still there
01:53 MadcapJake i wiped the rakudo directory completely
01:53 Zoffix Did you nuke both .rakudobrew and .perl6?
01:53 MadcapJake the source dir
01:53 MadcapJake no i should do that then
01:55 zengargoyle MadcapJake: i think the spell is: rakudobrew nuke moar; rakudobrew self-upgrade; rm -rf ~/.perl6; rakudobrew build moar; ...
01:55 Zoffix MadcapJake, BTW:
01:55 Zoffix I misspelt your name tho :)
01:55 zengargoyle which avoids deleting .rakudobrew and re-installing it.

01:55 yoleaux 7 Dec 2015 18:58Z <ZoffixW> MadcapJack: Found a really annoying breakage of the syntax highlighter: apostrophes in regexes: say so "You're wrong" ~~ /'You\'re wrong'/;   That breaks all the following code after that line :(
01:56 Zoffix MadcapJake, and props on making the highlighter work. it detects all the incorrect keys :D MadcapJake++
01:57 MadcapJake what you mean by detects the incorrect keys?
01:57 Zoffix (I also found a way to get around that highlighter issue: add # ' after the regex
01:58 Zoffix MadcapJake, I don't have Atom on this box,but I had "authority" IIRC, and it was highlighted in a different colour than all the other keys that ARE listed in the META spec
01:58 glaukommatos Does the existance of a perl6-debug-m but no perl6-debug indicate that I've built something wrong and/or happen to explain why perl6-debug-m does not stop at my breakpoints? :)
01:59 Zoffix MadcapJake, like, if you open this META in Atom, all keys will be in blue, but "authority" will be in different colour:
01:59 flussence glaukommatos: not having `perl6-debug` is normal, can't speak for the rest
02:00 MadcapJake Zoffix: and you liked that or didn't?
02:00 glaukommatos Mmm, perhaps I ought not to trust the homebrew package then.
02:00 Zoffix MadcapJake, definitely did :) I didn't even realize authority was not a proper key :)
02:00 MadcapJake ahhh! yeah I looked at the spec and put special case highlighting for each true meta6.json key
02:00 Zoffix MadcapJake++
02:01 MadcapJake cool! glad you liked it! I was worried i missed a key :P
02:02 hoelzro flussence: %?RESOURCES doesn't get installed; that's just because of a hack I put in Linenoise

02:12 Ben_Goldberg joined #perl6
02:14 glaukommatos So, I hope someone familiar with the debugger might be able to point out something silly I'm doing. I run my p6 file with perl6-debug-m filename.p6; then I do bp add <linnum> and press enter; then I type r and press enter. I expect the debugger to stop at <linnum>, but instead it just goes straight on through the rest of the file. Is this the expected behavior, or is something weird?

02:20 Ben_Goldberg joined #perl6
02:22 adu glaukommatos: I've only used the grammar debugger
02:22 adu glaukommatos: I've never used the regular debugger
02:26 glaukommatos Interesting. It seemed like perl6-debug-m was allowing me to step through the grammar in my p6 file. Am I confusing the grammar debugger with the normal debugger? How do you normally invoke the grammar debugger?
02:28 zengargoyle i think Grammar::Debugger and Grammar::Tracer are activated by 'use Grammar::Debugger;' in your code.
02:29 zengargoyle like you just 'use' it before you define your own grammar and magic happens.
02:30 Zoffix use Grammar::Debugger; lets you see and step through the grammar matching process. use Grammar::Tracer; just prints the matching tree.
02:30 glaukommatos Interesting. I haven't got any such use statements. But when I run with perl6-debug-m file.p6 it still lets me step through the whole process (which is really freaking amazing, btw). I need to read more docs!
02:31 zengargoyle but i seem to recall a bit about being able to do the same with the perl6-debug-m mostly.  as in perl6-debug-m is powerful enough to go all the way down ...
02:32 cdg joined #perl6
02:32 Ben_Goldberg joined #perl6
02:32 glaukommatos Yeah, I know that when I step through with perl6-debug-m that it will go into detail during the parsing process if I do my MyGrammar.parse($string).
02:32 glaukommatos It's pretty awesome to watch the input string get consumed. <3
02:33 zengargoyle wonder if the breakpoint thing is it not finding the file/line properly since curli
02:34 zengargoyle since now they get turned into hashes and such.
02:34 glaukommatos I'm not familiar with curli.
02:40 lolisa joined #perl6
02:45 zengargoyle glaukommatos: debug seems to be working for me. at least adding a breakpoint and having it stop thereabouts.
02:45 Jeguen left #perl6
02:46 natefanaro joined #perl6
02:46 dj_goku any idea what is causing this warning: Trailing item in Hash.append
02:46 glaukommatos zengargoyle: Interesting. Would you be able to let me know what command you're using to add the breakpoint and then subsequently to run up to it? I'm trying to figure out if I'm just doing something stupid or not, since I'm not terribly familiar with the debugger's syntax.
02:47 skids m: my %h; %h.append(a,1,b);
02:47 yoleaux 7 Dec 2015 21:13Z <jnthn> skids: Thanks for the S17 gist; I look through it tomorrow when I've (hopefully) more brane :)

02:49 glaukommatos zengargoyle: Huh, that's so very strange. Well, at least I'm glad I'm not going crazy.
02:49 zengargoyle stops before doing line 16 showing lines 14-18 with line 16 highlighted.
02:49 glaukommatos zengargoyle: thanks
02:50 zengargoyle what type of line are you setting the breakpoint on?  a simple statement? a function call?
02:51 glaukommatos Oh shoot. You know what, I made a stupid.
02:52 glaukommatos I've been putting the line number of blank lines in front of the lines I care about. Don't ask me why I thought that would work.
02:52 glaukommatos I think gdb or something probably just rounds things to the nearest line that actually generates code, and somehow I've gotten into a habit or doing that.
02:53 zengargoyle heh
02:53 glaukommatos I just did it again with a line that, oh you know, actually had code on it. And surprise: it works.
02:53 glaukommatos I am not a clever person.
02:53 glaukommatos In other news, Grammars are easily the coolest language feature I've ever played with.
02:53 MadcapJake now for some reason make is crashing on me :(

03:21 zengargo1le autarch: ok, that worked... will read. :)
03:21 autarch thanks!
03:22 MadcapJake ShimmerFairy: why does it give me a permission denied if I try to install to there without using sudo?
03:22 ShimmerFairy weird
03:23 MadcapJake I used `--prefix=/usr/local` when installing perl6, which requires sudo right?
03:23 hahainternet MadcapJake: yes, /usr/local is part of the filesystem typically owned by root
03:23 geekosaur what platform?
03:24 hahainternet i assume someone else has mentioned rakudobrew already :)
03:24 geekosaur because on OS X with Homebrew, /usr/local is typically made writable by you
03:24 hahainternet oh i forgot OSX has wacky stuff
03:24 MadcapJake rakudobrew won't let me use commits I made to rakudo though right?
03:24 geekosaur this is not OS X stupid, it's Homebrew stupid
03:24 MadcapJake i'm on linux/ubuntu
03:24 hahainternet geekosaur: i'll stick with 'wacky' :D
03:24 geekosaur that and the curl|sh installer give me hives
03:25 hahainternet and MadcapJake i see, well i don't know much about rakudobrew but just create yourself a local directory for your builds
03:25 hahainternet i typically have ~/.local/projectname/ for local binaries, so golang and perl etc
03:27 zengargo1le autarch: are you going for ideal or actual? :)  pod outside of =begin pod/=end pod works just fine.
03:28 zengargo1le [ => 1, config => {}, contents => [ => {}, contents => ["NAME"])]), => 1, config => {}, contents => [ => {}, contents => ["SYNOPSIS"])])]
03:28 zengargo1le =head1 NAME␤=head1 SYNOPSIS
03:33 zengargo1le ah, maybe not say this "All Pod blocks must be delimited with =begin pod and =end pod markers." but go into the 3 types and then mention =begin pod/=end pod as a common container like thing.  mostly just means inside here is POD only, no code.
03:33 kaare_ joined #perl6
03:41 zengargo1le the example1.p6 code looks to have a spurrious 'perl6' as the first line....
03:41 dj_goku hmm.
03:42 dj_goku I am getting random failures with this code:
03:43 dj_goku oh I bet it is hitting thread limit.
03:45 zengargo1le Unlike with Perl 5, in Perl 6 Pod syntax is purely semantic. In other words, you describe what something is, rather than how to present it. -- in theory, Perl 5 pod is just as semantic... B<> still meant basis, I<> still important ... i think the only *format* thing was =over/=back maybe..
03:46 autarch zengargo1le: oh, I was just going by the synopsis on the begin/end thing
03:46 autarch zengargo1le: no, Perl 5 pod had =over 4, etc
03:47 zengargo1le maybe mention that =begin/=end wrap and =for/=block end at the first blank line.  maybe mention indenting.
03:47 Jesseract joined #perl6
03:47 zengargo1le yeah =over is the only sorta-formatting thing i can think of in Perl 5
03:48 zengargo1le and it ended up just being something to wrap =item in.
03:56 abraham joined #perl6
03:58 ShimmerFairy Pod 6 lets you use any kind of block in code, it's just that =begin pod/=end pod are the nicest (if not best) way of delineating a "document" instead of a couple blocks here and there :)
03:58 zengargo1le C<=pod>             No "ambient" blocks inside
03:59 autarch I'll change that part
04:01 ShimmerFairy e.g. you could use =head1, =head2, etc. on their own just to section parts of your file :P
04:02 zengargo1le =begin pod lets you have =head1 foo␤␤some para stuff␤␤   indented code example that if not in a pod section would be real code␤␤=end pod
04:03 zengargo1le actually, the para would be real code as well...
04:04 AW3i joined #perl6
04:06 zengargo1le autarch: otherwise, nothing jumps out as awkward or confusing... so looks pretty good.

04:27 zacts I think Perl5 had poor support? (or am I mistaken)
04:28 zacts Perl6 that is (caps 'P')
04:28 dj_goku zacts: checkout:
04:28 zacts cool
04:28 dj_goku zacts: what are you wanting to do?
04:29 zacts dj_goku: oh it was just a general curiosity question
04:29 MadcapJake oops apparently tilde in's prefix argument doesn't work :P
04:29 zacts although, I do have to say I love the nice and pretty web design of the Perl6 doc
04:29 vendethiel joined #perl6
04:30 zacts dj_goku: I'm just learning about concurrency from another language, and I am eager to try it out with Perl6 sometime
04:30 zacts but I think your link has all the answers I need for now
04:30 zacts so just curious... :-)
04:31 AlexDaniel jdong11: yeah
04:31 AlexDaniel jdong11: well, Perl 6 was pretty useful for quite some time now
04:32 AlexDaniel jdong11: so it should not be so surprising :)
04:32 dj_goku zacts: outside of just using gearman for queue client/worker. I haven't I don't have much experience. I am current working on examples and give a talk tomorrow about those things listed on the concurrency page.
04:32 zacts oh nice
04:32 zacts dj_goku: if you get a recording or slides, I would be interested
04:32 AlexDaniel zacts: long story short: it is pretty awesome
04:33 zacts AlexDaniel: nice!
04:33 MadcapJake is there any way to improve how fast the parse stage is for compiling rakudo?
04:33 MadcapJake how long does it take people?
04:33 AlexDaniel MadcapJake: a few minutes
04:33 MadcapJake Mine takes 83.585 seconds
04:33 hoelzro MadcapJake: a minute or two
04:33 zacts All this progress with Perl6, and an upcoming release, is making me eager to learn enough to contribute towards Perl6 modules
04:33 hoelzro that's pretty typical
04:33 AlexDaniel zacts: that'd be great!
04:34 hoelzro zacts++
04:34 zacts =)
04:34 zacts is rakudo implemented in C?
04:34 hoelzro rakudo is implemented in NQP
04:34 MadcapJake why do I need sudo to install to ~/.local o_O
04:34 hoelzro which is a subset of Perl 6
04:34 hoelzro MadcapJake: o_O
04:34 dj_goku zacts: lol I am just now starting the night before. Not sure how well it'll go. :D
04:34 dj_goku zacts: coders block.
04:35 MadcapJake "mkdir /home/jrusso/.local/share/nqp/lib/Perl6: Permission denied at /usr/share/perl/5.20/ExtUtils/ line 288.'
04:35 AlexDaniel hoelzro: I thought that parts of it are full-blown Perl 6, am I wrong?
04:35 zacts dj_goku: oh that's cool
04:35 hoelzro AlexDaniel: ah, yes, good point
04:35 zacts if it's a success just /msg me tomorrow or wednesday
04:35 hoelzro src/core/ is in Perl 6
04:35 zacts it's monday still in my timezone
04:35 zengargoyle MadcapJake: did you sudo something that touched .local previously?  sometimes you can sudo and muck permissions so that you don't own it anymore...
04:35 hoelzro the rest (barring a few VM-specific things) is in NQP
04:35 zengargoyle sudo chow -R you:yourgroup .local
04:35 dj_goku zacts: CDT here.
04:35 AlexDaniel zacts: MoarVM though is implemented in C
04:36 zacts MDT USA here
04:36 dj_goku zacts: colorado?
04:36 zacts New Mexico
04:36 dj_goku 42 seconds to 'stage parse' here!
04:36 dj_goku zacts: ahh sweet. where at?
04:36 zacts ABQ
04:36 AlexDaniel zacts: but most of the time it should not matter for you much since most contributions are actually happening in rakudo
04:36 dj_goku albq has an awesome balloon festival. :D
04:37 zacts AlexDaniel: ah nice, so rakudo is mainly implemented in Perl6, and the VM it runs on top of C?
04:37 AlexDaniel zacts: correct
04:37 zacts neato
04:37 zacts well, hopefully I can get involved soon
04:37 AlexDaniel zacts: well, Perl 6 and NQP. NQP is not quite Perl 6, so you can't say that it is just Perl 6 :)
04:37 zacts even if just a few patches
04:38 zengargoyle albu has awesome green chile
04:38 hoelzro the plus of working on Moar is that your compile times are a lot shorter =P
04:38 AW3i how are the performances fairing currently vs perl5
04:38 zacts zengargoyle: indeed
04:38 AW3i i've seen some graphs some months ago they looked decent
04:38 AlexDaniel AW3i: depends
04:38 hoelzro MadcapJake: depdending on what you're doing, there are some tricks you can pull to get around having to parse
04:38 AlexDaniel AW3i: startup time is a bit slow-ish
04:39 AlexDaniel AW3i: everything else is indeed decent, but if you start doing some heavy tasks you may find it really slow
04:39 AW3i oh ok thanks
04:40 AW3i sadly I don't have the time to play around with perl6 yet :/
04:40 hoelzro MadcapJake: are you still working on the Perl6::Compiler stuff?
04:40 MadcapJake hoelzro: yeah
04:40 AlexDaniel AW3i: well, feel free to abuse camelia here

04:41 MadcapJake hoelzro: well i was having trouble testing it within the src dir because it was looking in the wrong place.  So then I fumbled around getting it to properly install, now I'm hoping that I'll have it in ~/.local *fingers crossed*
04:42 * hoelzro crosses fingers too
04:42 hoelzro let me know if you need another pair of eyes on it!
04:42 MadcapJake alright, thanks!
04:43 hoelzro I feel like I got you into this mess =/
04:43 hoelzro but hey, if you stick with it, future contributions to Rakudo will be a cinch ;)
04:44 dj_goku hehe
04:44 MadcapJake looks like perl6 installed, now panda is giving me permission errors: Failed to open file /home/jrusso/github/panda/ext/Shell__Command/lib/.precomp/.lock: permission denied
04:44 MadcapJake I tried to run `perl6 --prefix=/home/jrusso/.perl6
04:45 zengargoyle MadcapJake: you probably have previous sudo damage left over.
04:45 zengargoyle created something as root, now can't touch it anymore.
04:45 MadcapJake gah, that's what happened to my .local folder too xD
04:45 zengargoyle what it sounds like to me.
04:46 * zengargoyle has done that often enough.....
04:46 dj_goku delete all the things!
04:46 zengargoyle sudo chown -R
04:46 MadcapJake to what though?
04:46 dj_goku or that.
04:46 MadcapJake I deleted .perl6, and it's still saying that o_O
04:46 zengargoyle _Command/lib/.precomp/.lock
04:47 zengargoyle get rid of all the .precomp files under panda/ext/*
04:47 zengargoyle or chown them
04:48 MadcapJake `sudo rm -rf ~/github/panda/**/.precomp` did the trick
04:49 WizJin joined #perl6
04:54 AlexDaniel I wonder what would be the shortest Perl 6 program demonstrating most of its killer features. e.g. 「say τ² * ½」 is already cool, now add some hyper operators, phasers, junctions, multiple dispatch, infinite lists, async stuff…
04:55 hahainternet use unicode division instead of ugly * :)
04:55 AlexDaniel hahainternet: unicode division?
04:55 hahainternet but yeah, you'd want to build some sort of infinite list using tau² and do so in a threaded manner i guess
04:55 hahainternet AlexDaniel: there are unicode symbols for division, i don't know if any are supported

07:57 _nadim Good morning everyone.
08:02 moritz \o
08:10 glaukommatos joined #perl6
08:15 masak morning, #perl6
08:15 yoleaux 00:52Z <ShimmerFairy> masak: I just had a thought about the ugly {{{}}} syntax: what about a vaguely Lisp-inspired `{} ? After all, the backtick is free in P6 :) . (Though I don't think it'd have quite the same meaning as `(), hence "vaguely inspired")
08:16 masak ShimmerFairy: it'd have the "opposite" meaning. unquotes are more akin to the ,myvar syntax. using `{} would be needlessly confusing.
08:17 masak as for myself, I'm starting to come around to keeping {{{ }}} :)
08:17 masak (but I've had a few cycles of disliking it and liking it again, so who knows where we'll end up)
08:17 masak more pressing now than syntactical concern is getting the semantics goodenuf
08:17 moritz what I really dislike about {{{}}} is that it's mis-parsed as nested blocks if it's a place where we expect not {{{}}}
08:18 ShimmerFairy masak: again, hence "vaguely inspired". I just thought of it as something distinct-looking (using backtick) that doesn't suck, which happened to be inspired by looking at lisp stuff :)
08:18 masak moritz: yes, that's obviously not going to be acceptable in the long run
08:18 masak ShimmerFairy: yes, but ` is Lisp for "quasi", not "{{{ }}}"
08:19 masak (though as pdcawley points out, Perl 6's quasiquoting construct is different enough that maybe it shouldn't even be called "quasi")
08:20 ShimmerFairy masak: while true, I don't think that's a good argument for not doing it. My thought process was just "Hey, what if this `() looked like `{} and we used it instead of {{{}}}? That ` would highlight something very different going on"
08:21 masak ShimmerFairy: "strangely consistent" is all about using loose connections people have in their brains, so that a feature feels syntactically vaguely right for various reasons. your proposal does the opposite.
08:23 ShimmerFairy masak: eh, if I didn't mention the very-vaguely Lisp-inspired bit, you probably wouldn't've noticed. And I think "we don't use the backtick" far far far outweighs "a Lisper might somehow get momentarily confused perhaps"
08:24 * masak goes and does something else
08:25 vytas just use unicode characters until you come up with suitable texas version (=
08:25 * vytas doesn't know what {{{}}} does though :)
08:26 sno joined #perl6
08:26 TEttinger is not using any non-english-keyboard characters called texas because "we speak american in texas"?
08:26 masak vytas: it's a "hole in the program" where macros can put in program fragments.
08:28 TEttinger or is it related to texas instruments in some way
08:28 masak TEttinger: it's "Texas" because the ASCII variants are longer, and everything's bigger in Texas.
08:28 TEttinger ha
08:28 masak ⦃ ⦄ is probably the closest Unicode equivalent to {{{ }}}
08:28 TEttinger haha
08:29 masak but I don't see that we need to go there
08:29 TEttinger m: say ⦃ 1 ⦄

09:46 _nadim hi, given a class with a routine, can I get the routine object? something like $routine = C::D::routine
09:47 mohae joined #perl6
09:47 llfourn _nadim: C::D::<&routine>
09:47 _nadim thanks
09:47 llfourn it should be our scoped though
09:47 timotimo llfourn: that only works if the routine is an "our" routine, no?
09:47 timotimo yeah
09:47 llfourn :D
09:48 timotimo m: class T { our sub foo() { say "ohai" } }; T::foo(); my $sub = T::<&foo>; $sub()
09:48 camelia rakudo-moar 036e19: OUTPUT«ohai␤ohai␤»
09:48 * grondilu thought the syntax was &T::foo
09:48 * llfourn thinks you can do it that way too
09:48 timotimo i think so, too
09:48 cosimo w/in 27
09:49 _nadim how does one get
09:49 xinming joined #perl6
09:49 * timotimo doesn't get
09:49 grondilu the suspense is unbearable
09:49 _nadim Oops, I meant that I can get something that is not declared as our but I get an Any, not a Routine
09:49 llfourn m: class T { method foo { say "ohai" } };; # _nadim: to me this is clearer
09:49 camelia rakudo-moar 036e19: OUTPUT«ohai␤»
09:50 llfourn _nadim: can you gold what you are trying to do?
09:50 _nadim llfourn: I am writting a dumper
09:50 grondilu if it's not declared as "our", it's declared as "my".  So you can't access it from the outside.
09:50 _nadim I want to test what it does when it get a routine
09:51 llfourn _nadim: if you are writing a dumper you should use the MOP to introspect the class and dump stuff
09:51 _nadim URL please
09:51 llfourn m: class T { method foo { say "ohai" } }; .say for T.^methods;
09:51 camelia rakudo-moar 036e19: OUTPUT«foo␤»
09:52 _nadim but in this case I am not dumping a class, just a Routine
09:52 jdong joined #perl6
09:52 llfourn _nadim: what do you mean by "Routine"?
09:52 llfourn Routine is a role afaik
09:52 jdong perl6, amazing !!!!

09:54 _nadim llfourn: good to know, so I can't get objects that are just routines
09:54 stmuk can anyone reproduce [perl #126840] $*KERNEL and env lookup?
09:54 llfourn Methods, Submethods and Subs are routines I think
09:54 _nadim Sub is too
09:54 stmuk I have seen that warning on building panda but not how described in the ticket
09:55 _nadim sorry, didn't scan the Sub in your comment
09:55 pippo joined #perl6
09:57 gfldex _nadim: and you can get stuff that you are not looking for when talking to the dispatcher. see: (and a few other things)
09:57 _nadim says that Sub is derived from Routine, and says it is a class not a role
09:58 llfourn _nadim: that's why we have docs :)
09:58 llfourn m: say
09:58 camelia rakudo-moar 036e19: OUTPUT«Cannot make a Routine object using .new␤  in block <unit> at /tmp/gLB0RfEbrb:1␤␤»
09:59 llfourn you are right it's a class
09:59 _nadim docs will get better, that's the way of docs ;)
10:00 _nadim gfldex: thanks, I'll check
10:06 llfourn _nadim: what is Data:::Dump::Tree?

10:44 RabidGravy fabulous
10:44 timotimo it's hard to tell how many views each article has gotten, because we don't have "read more" buttons on most of them
10:45 timotimo but it seems like the "unicode, perl6 and you" article has been getting a bunch of direct links: 2.6k views

10:47 timotimo it was also discussed on hackern00z
10:55 RabidGravy I do think the sheer fabulousness of the unicode implementation is going to be the winner, people can bitch and moan about the OO, about the functional features about the sigils but there's no gainsaying the unicode stuff

11:14 RabidGravy (i.e. a '=head3' )

11:16 ShimmerFairy timotimo: for the record I'm still shocked my post could be so popular :3
11:16 timotimo hehe

11:22 ShimmerFairy Yeah, it'd be funny if it's all because "hey, hear about this weird old bug?" :P

11:26 timotimo FWIW, your post is the only post from this years advent calendar that's in the top 10 viewed posts
11:26 timotimo but Home page / archives is a very distant first place
11:26 timotimo i have no clue if fetching new articles by scrolling down is properly stat'd, either
11:29 Woodi yes, there is around 50% unused space! menu with posts or days or even years would be great

11:32 lizmat yeah guys, no pressure  :-)
11:32 timotimo all i can do is scroll through the list of available free themes and try to find one that's all right
11:32 Zoffix ShimmerFairy, well, go pick a good theme that provides that :)
11:32 ShimmerFairy Zoffix: I couldn't see the theme chooser when I looked, but I'll be sure to check again :)
11:33 timotimo actually
11:33 timotimo it doesn't seem like i have anywhere to configure themes and such
11:33 Zoffix ShimmerFairy, timotimo "Customize" bottom right, then top left there's a "Choose theme" area
11:33 Zoffix Or "Active Theme" rather, with a "Change" button
11:34 timotimo i don't have a customize button there
11:34 RabidGravy lizmat++ # just because
11:34 RabidGravy jnthn++ # hugs
11:34 timotimo it seems like i can get the theme for my own wordpress site
11:36 Zoffix timotimo, another way is to go to and choose "Appearance" on the left middle
11:37 RabidGravy llfourn, I think I'll go with "=head3 The C<$> anonymous state variable
11:37 Zoffix Hm, same place has "Widgets" page... maybe you can add the stuff you want from there on any theme
11:37 RabidGravy this may enhance searching
11:38 timotimo Zoffix: no such entry in that menu
11:38 _nadim Any eample of using a shared enumeration somewhere?
11:38 llfourn RabidGravy: um maybe I'm not sure if it will work? lemme check :)
11:38 timotimo _nadim: "shared"?
11:38 RabidGravy this is why I said "may" ;-)
11:39 masak lol, I blogged!

11:40 timotimo masak: if you ha dposted that yesterday, it'd have gone into the weekly immediately!
11:40 RabidGravy masak++
11:41 masak hehe
11:41 _nadim timotimo: defined in a place and used in other places
11:41 masak maybe there will be a weekly next week... ;)
11:42 Zoffix timotimo, are you timojbo?
11:43 llfourn RabidGravy: I can't even find the code where it specifies what headings it looks for to make auto links
11:43 llfourn but I'm sure it exists!
11:43 timotimo i am, yes
11:43 timotimo _nadim: if you could only use enums where they are defined, they would be pretty useless
11:44 _nadim Indeed!
11:44 Zoffix timotimo, you should have the theme thing now (if not, try logging out and logging in again)
11:44 timotimo but ... but ...
11:45 Zoffix ?
11:45 timotimo i don't even *want* to fix this myself :<
11:45 * Zoffix laughs
11:45 llfourn RabidGravy:
11:45 llfourn ^^ that's the regex
11:45 timotimo seriously. web dev can be such a pain. and wordpress "web dev" is the absolute worst
11:46 Zoffix But it's not web dev. It's you using an annoying interface to click on a bunch of pictures to see if the website looks fine to you :)
11:47 timotimo urgh
11:47 timotimo i'd rather have my brain pulled out through my nose with a red-hot metal hook
11:48 timotimo yeah, the "themes" button just appeared
11:48 timotimo i didn't have to refresh, which i guess is cool
11:48 Zoffix :)
11:50 ShimmerFairy between the theming and the content-mangling, I propose we develop our own blogging platform for Advent 2016 :P
11:50 timotimo;theme=pub/satellite - this one gives us a "menu" button on the top left (burger menu) where we can put an entry for every table of contents post
11:50 timotimo ShimmerFairy: yes, please!
11:51 RabidGravy llfourn, so no it wouldn't work :-(
11:51 timotimo ShimmerFairy: then we can also have a proper "preview & get feedback" mode for my weekly blog, too ... pretty please with a cherry on top
11:51 llfourn RabidGravy: doesn't look like it atm :\
11:51 Zoffix ShimmerFairy, well volunteered! :D
11:51 ShimmerFairy timotimo: heh, I think it would want to be called "october" or something, in keeping with the... pattern?... set by that old "november" thing :)
11:52 timotimo hahaha :)
11:52 timotimo MarchOfThePostuins
11:53 llfourn RabidGravy: best to stick with The C<$> Variable for now :)
11:53 RabidGravy yeah, going to
11:53 ShimmerFairy It'd probably be a really good test of Perl 6 for CGI actually, esp. compared to when masak did november :)
11:53 Zoffix CGI? Bruh, 1990s called, they want their stuff back
11:53 timotimo ShimmerFairy: is there a name for the Bleemth month of the year?
11:54 timotimo ShimmerFairy: i hope you don't *actually* mean CGI :)
11:54 ShimmerFairy timotimo: Bleemth?? (and yes, not CGI the specific thing, but CGI the vaguer concept of Common Gateway Interface)
11:54 Zoffix And I can tell you the results already: Perl 6 would suck at it, due to slow start up time (which has to happen when dealing with CGI for every page load)
11:54 timotimo  -  TL;DR: there exists a secret integer between 2 and 3
11:55 Zoffix Which is one no one uses CGI anymore :)
11:55 timotimo Zoffix: tthat's also why ShimmerFairy didn't mean actual CGI
11:55 lucasb Sure someone could write a blog thing in Perl 6. On the other hand, there is no need to reimplement this, since Jekyll already exists :) There is no shame in using a tool written in another language. I would really like if in the future, both weekly and advent blogs used jekyll
11:55 matt_ joined #perl6
11:55 timotimo lucasb: how's the "authoring" part of jekyll?
11:55 lucasb I think having a domain would be cool
11:55 timotimo yeah, and have it be at least a little better than the movable type installation on ...
11:56 lucasb timotimo: what authoring mean? I think it is just markdown files :)
11:56 ShimmerFairy lucasb: there's definitely no shame if we've lowered ourselves to using PHP of all languages :D
11:57 timotimo lucasb: that's not good enough.
11:57 ShimmerFairy lucasb: but I do think a p6-based blogging platform would be really cool for showing off Perl 6 and so on.
11:57 koo8 joined #perl6
11:57 ShimmerFairy timotimo: a P6-based platform would be able to use the (spec'd) power of Pod6, now that it's brought up :)
11:58 timotimo that would be cool, but i'd also ask for a javascript-in-the-browser instant-preview-as-you-edit feature
12:00 ShimmerFairy as long as it doesn't perpetually mangle angle brackets and the like, it'll be an improvement :P
12:00 timotimo YES
12:00 timotimo oh lord, those angle brackets
12:00 glaukommatos joined #perl6
12:01 timotimo ugh, the left-side slide-out menu steals a lot of screen real estate on a phone
12:03 timotimo;theme=pub/kelly - this almost looked promising until i saw it brings out horizontal scrollbars because the link doesn't wordwrap
12:06 timotimo cool. my browser now has three vertical scrollbars on the very right. only one of them "active"
12:08 * gfldex .oO( it's scrollbars all the way down )
12:08 Woodi masak++ # blogpost
12:11 tadzik oh, the idea was for posts to be up as soon as the day starts :o

12:11 tadzik my bad :(
12:11 timotimo ;)
12:11 timotimo it's all right
12:12 tadzik let's maybe pull in Day 9 now and I'll have mine ready for tomorrow?
12:12 tadzik to minimize the delay
12:12 |Tux| why does «my $fh = open "non-existing.weird.ext", :r or warn "Bummer!"» cause an exception instead of a warn?
12:13 El_Che timotimo: I have now sample code for the react+channel bug :
12:13 nine |Tux|: I hope that's because Perl 6 fixed one of Perl 5's mistakes there ;)
12:13 El_Che about 15% of the time, this code get something like a deadlock
12:13 lizmat nine: shouldn't that return a Failure, though ?
12:13 nine lizmat: oh, true, we have Failure
12:14 Ch0c0late joined #perl6
12:15 rurban joined #perl6
12:15 tadzik masak: ping
12:15 |Tux| nine, for me that dwim's. What is the perl6 way to do it?
12:15 timotimo El_Che: yeah, i see it's behaving strangely
12:15 |Tux| and, maybe more interesting, where do you see the flaw in perl5 approach
12:16 nine IO::Handle::open contains this: # TODO: catch error, and fail()
12:16 timotimo [Tux]: "or" doesn't have "try" semantics automatically
12:16 timotimo [Tux]: when open finds an error, it throws an exception, so you don't have to "open ... or die" all the time everywhere
12:16 El_Che nine: the thing is, this code shouldn't fail
12:17 |Tux| if (my $fh = open "frubble.hyg", :r) { neither?
12:17 timotimo [Tux]: maybe "orelse" would do the trick, as it has "exception semantics"
12:17 timotimo m: die "oh no, file not found" orelse warn "bummer!"
12:17 camelia rakudo-moar 036e19: OUTPUT«oh no, file not found␤  in block <unit> at /tmp/eYEdWYPXLD:1␤␤»
12:17 timotimo hm, no. still needs to  have a try
12:17 nine |Tux|: Perl 5 swallows such errors leading to action at a distance. You have to check every call manually or use autodie; How many people do you know who check the result of every print or say?
12:17 timotimo m: try die "oh no, file not found" orelse warn "bummer!"
12:17 camelia rakudo-moar 036e19: ( no output )
12:17 |Tux| many :)
12:17 timotimo and the precedence of "try" is too loose to get the warning
12:18 |Tux| nine, at least I know me, myself and I
12:18 nine |Tux|: so you're the ONE!
12:19 kid51 joined #perl6
12:20 timotimo El_Che: indeed, all threads are in uv_cond_wait here.
12:20 El_Che timotimo: it also happens with 1 file, but less often
12:20 timotimo El_Che: one from "shift", which is likely the whenever on the channel trying to get the next value
12:21 vytas am I blind or it is really telling that there are 4 comments, but shows only 3 ?
12:21 moritz vytas: it's really doing that
12:22 El_Che timotimo: I'll simplify the code on the gist by using only 1 instance
12:22 * |Tux| mubmles that Path should have an .exists and a .non-empty method
12:22 vytas thanks : )
12:22 timotimo moritz, vytas, the fourth "thought" is the pingback at the very bottom, i think?
12:22 timotimo hm, no, actually not
12:22 * El_Che wished that the bugtrack would be on github
12:23 lizmat m: "foobar".IO.e.say   # [Tux]
12:23 camelia rakudo-moar 036e19: OUTPUT«False␤»
12:23 * moritz never understand what pingbacks are for
12:23 timotimo lizmat: that's not the only reason open could fail
12:23 ChoHag joined #perl6
12:31 El_Che timotimo: here is the simplified class:
12:31 El_Che timotimo: I'll post a bugreport based on that
12:33 timotimo El_Che: i just copy-pasted both workers together into the get_data method and made the channel a "my" instead of a "ha"
12:33 timotimo "has". and it still hangs sometimes
12:34 ShimmerFairy vytas: could it be counting the pingback?
12:34 El_Che ok
12:35 timotimo ShimmerFairy: it's not "a pingback", it's the link you're supposed to use to pingback
12:35 ShimmerFairy (pingbacks are on occasion "pending comments")
12:35 timotimo El_Che: and now i removed the class entirely, replacing it with a sub. it still freezes sometimes
12:35 ShimmerFairy timotimo: huh? I'm fairly certain I've heard of pingback as a noun, not a verb :)
12:35 timotimo ShimmerFairy: could be, but not in this case; it shows 0 commits pedning review :|
12:36 timotimo ShimmerFairy: i can verb whatever i want :)
12:36 ShimmerFairy timotimo: well, I recall approving some comments for perl6advent, among which were pingbacks from weekly :)
12:36 vytas not sure what is it but for instance here -> it says 1 comment but none exist so either it starts counting from 2 or includes pingback
12:37 ShimmerFairy yeah, I'm certain it counts pingbacks as comments
12:38 timotimo hmm

13:03 vytas in perl6 REPL can i somehow save the session and restore it later ?
13:03 masak vytas: nope.
13:03 Skarsnik try 2015.10 or the most recent version. some stuff are still buggy with panda/module
13:03 MadcapJake not yet, i am working on adding that

13:05 vytas spacebat, do self rakudobrew self-upgrade first
13:05 spacebat yup have done already
13:05 MadcapJake what message do they give?
13:05 MadcapJake oh i see :P
13:05 timotimo El_Che: i don't know if this helps, but it looks like the "shift" entries in the backtrace are from the scheduler waiting for jobs on its job queue
13:05 MadcapJake it's early for me xD

13:10 timotimo good
13:11 stmuk is anyone looking at the %ENV warning issue?
13:11 vytas MadcapJake, awesome, I assume you will commit it in the core ? is there a way to extend ::Compiler outside core?
13:11 timotimo we could try running the whole thing in a loop and see if we can get it to 100% freeze rate (if left running long enough) or if it'd either work forever or freeze early
13:12 masak today in your "Unicode is hard" news reporting:
13:13 pippo vytas: you can have REPL commands history saved for later re-use with rlwrap.
13:14 timotimo fantastic

13:58 llfourn mm yes I was asking about w/o arguments
13:58 lucs I may have missed earlier arguments, but wouldn't initializing to the current moment be a useful default for an argumentless
13:58 RabidGravy so => 2015, month => 12, day => 25) is still cool
13:59 moleculesoflife mortiz++ Thank you. I really like Christmas Eve and Christmas and everything, but just didn't expect it in that context.

14:01 tadzik I'll give it one last proofread and push it live, I'll appreciate a second pair of early adopters' eyes :)
14:01 Juerd "now" would be incorrect, because "now" is much more specific than "today". To get today's date, something like would make more sense than
14:02 BooK also, TZ
14:02 RabidGravy "full meta jacket"
14:02 Juerd BooK: Anyway.
14:02 llfourn Juerd: is a thing
14:02 ChoHag Is there a more perl6-ish way to say [ <foo> <.sep> ]* <foo>?
14:02 Juerd llfourn: Yes, because date + time is as specific as the concept of 'now' can be expressed.
14:02 BooK llfourn: I think this is exactly what Juerd meant

14:04 Ven I almost have a blog post ready for today, should I go for it? If people can give me their input
14:04 BooK sjn: I think it's the same reason for both
14:04 Juerd sjn: 1 is *'s identity. It's the number you can prepend to the list of things to multiply without changing the outcome.

14:05 Juerd BooK: No, / doesn't have identity like that because  4 / 4 and x / 4 / 4 are different for every x.
14:05 moritz BooK: no, because you can't just add 1's to a list that you pass to [/] without changing the result
14:05 tadzik Ven: hey, I'm for today :)
14:05 BooK depends if you push or unshift
14:05 Ven tadzik: okay, I wasn't sure if you were gonna get to it or not :)
14:06 Juerd BooK: It's about unshifting.
14:06 tadzik I am, I'm just late :/
14:06 Ven np :)
14:06 Juerd BooK: It's whatever *starts* the process, in the implementation: my $x = identity; for @foo { $x op= $_ }
14:06 ShimmerFairy Juerd: prepend or append? (after all, appending means 4 / 4 / 1 / 1 / 1 ... would be identity)
14:06 Juerd ShimmerFairy: ^
14:07 ShimmerFairy ah, alright then :)
14:07 Juerd But I read somewhere that it's actually a mathematical thing, widely accepted etc, and not really an implementation detail.
14:07 Juerd But the implementation explanation works for me
14:08 moritz if you talk about neutral elements of non-commutatitive operations, you have to talk about the side on which you apply it
14:08 moritz and we don't want to go to such lengths in Perl 6

14:09 ShimmerFairy moritz: in particular, that corroborates ** having an identity of 1 (so... "prepend" in direction of associativity?)

14:19 darutoko one more question
14:19 darutoko is there a way to check if string is number?
14:19 Juerd Why only one more? There's no limit on the number of questions you may ask :D
14:19 darutoko :)
14:20 BooK there might be a limit on the number of answers you get, though
14:20 Juerd darutoko: "is" a number is a bit hard, because there's no single definition for it.

15:14 Skarsnik creating a perl6 modules goes this way for now: Create a github repository, write a, put your stuff in lib/ write some test, eventually a travis.yml. and that it

15:16 AlexDaniel m: my int @a[8]; say @a[3].WHAT
15:16 camelia rakudo-moar 240b9a: OUTPUT«(Int)␤»
15:17 Skarsnik _nadim, there are some work for a cpan for perl6. the short answer : "It's not that easy"
15:18 Ven timotimo: `int @a[8]` can be used with nativecall, right? does it give anything better over `int @a`?
15:18 Skarsnik no
15:18 _nadim I am not, not too much at least, more silly than anyone else, and here I am preparing to write tests, I know where to put them, hmmmm how do I run them? I understand that those look like useless details but if people are going to do P6 on a scratch pad and then wait, we may not get as many people using it as we wish.
15:18 Skarsnik NC will need a CArray[int]
15:18 moritz _nadim: perl6 -Ilib t/your-test.t
15:19 moritz _nadim: PERL6LIB=lib prove -e perl6 t/
15:19 Ven Skarsnik: so, size of the natively typed array "only" gives contiguous memory guarantee?
15:19 _nadim p5 prove?
15:20 moritz _nadim: yes (though a p6 prove is being worked on)
15:20 moritz leont++
15:20 _nadim Has someone taken on himself all those nasty management questions?
15:20 moritz but the protocol is the same
15:20 Skarsnik Ven, no idea, NC is quite... weird x)
15:20 moritz _nadim: not yet. THanks for volunteering!
15:21 Skarsnik A big step will be a more complete doc about writing modules :)
15:21 _nadim I may, BooK will help me, I vonlonteer him
15:21 csd_ joined #perl6
15:21 BooK I first need to write my first module
15:21 RabidGravy lucasb++, added documentation for C<@> and C<%> anon variables as well, that's probably what killed dalek
15:21 _nadim that's what I am doing right now too
15:21 BooK so you're already ahead of me!
15:21 Skarsnik for now it's mainly "look at other modules"
15:21 Ven moritz: not sure how to get a post as "preview" on wordpress?
15:22 Ven okay, found it
15:22 moritz Ven: you press the "preview" button :-)
15:22 DrForr I just use -Ilib, that's why I removed the @*INC stuff from my libraries instead of adding 'use lib'. But that's just me.
15:22 Ven moritz: can you give me your input on;preview=true&amp;iframe=true ?
15:22 moritz Ven: subject should start with "Day $n - "
15:22 _nadim BooK: let's talk a bit later, maybe I can get you to do something for once ;)
15:22 Ven moritz: it doesn't have a day yet :P
15:22 jnthn Some people seem to have utterly missed the point that is about declaring a stable *language* so that people will feel investing time on advancing the infrastructure is worthwhile, because their work won't break next week/month. It is *not* some magical "we have a super mature ecosystem out of nowhere" point; I don't know why anyone would reasonably expect that. :)
15:23 moritz Ven: "PDL" could be a link
15:23 BooK I have a micro-hackathon (4 hours) planned for Friday evening
15:23 jnthn I'm really happy people already are doing a great amount of work on our documentation, module ecosystem, and so forth.
15:24 jnthn Especially while we're still tightening up the last things before Christmas and so have visited some icky breaking changes on them.
15:24 BooK jnthn: but I thought Perl was all about magic?
15:24 Ven moritz: done
15:24 moritz Ven: IMHO it needs some kind of punch line
15:25 Ven moritz: definitely does. There's no "end" :)
15:25 _nadim we are happy too, it's just that we can't do like Napoleon, the administration will not follow, because this is a spaceship and they are hard to follow, specially when they travel in hyperspace.
15:25 Ven :(*
15:25 jnthn But I'm under no illusion that we'll still have lots and lots to do in that area.
15:25 Skarsnik unrelated. Should NativeCall be renamed or something? I think it's really confusing to have native perl6(npq?) type like int and that get mixed with "native/ctype"
15:25 moritz Ven: for example, doing the math about how much storage my int @a[4;4] vs. normal arrays use, ,or something
15:25 _nadim jnthn: I think a lot of people are very happy already, I am.
15:26 moritz Ven: or even better, a benchmark of matrix multiplication, one using ordinary arrays, one using NSA
15:26 lucasb Thanks for writing those docs, RabidGravy++ :)
15:26 jnthn _nadim: I'm glad; I wasn't addressing you in particular, just a general sentiment that I've seen.
15:28 _nadim jnthn: I got that :)   IMHO, the super nifty stuff can wait for the little practical things to be in place, once I get a little hold of this, I may be able to help.
15:28 jnthn :-)
15:28 lucs In the REPL, can I force "use My:InDevelopment::Module" to load again?
15:29 RabidGravy jnthn, I still think we should aim for the 500 modules in the ecosystem, just *because* ;-)
15:29 jnthn RabidGravy: Works for me ;-)
15:29 Skarsnik lol
15:29 _nadim RabidGravy: how many are they right now? not that it matters.
15:29 Skarsnik around 470
15:30 Ven moritz: ah, yeah. int is int8 on 64-bit machines, right? so I can just do 4*4*8 bytes :P
15:30 _nadim easy!
15:30 Skarsnik int is int64?
15:30 zakharyas joined #perl6
15:30 jnthn Skarsnik: In Rakudo, always, yes. By the Perl 6 design docs, it'd be allowed to be 32-bit too.

15:31 zengargoyle good * #perl6
15:31 jnthn (And it's not actually a Rakudo thing, more a consequene of he underlying VMs)
15:31 RabidGravy so #perl6++ doing good
15:31 jnthn *the
15:31 Skarsnik Oh it's something I should add in my nc::typediag, not accept int in cnative stuff
15:32 AlexDaniel in fact, we've just seen how one module was removed. And that's good!
15:33 zengargoyle is the %?RESOURCES thing back to a point where it should possibly work?
15:34 Ven jnthn: my int @a[4;4] => 4*4*8 bytes, right? what's the "overhead"?
15:34 RabidGravy I added a module about six months ago, noticed that tony-o had made something almost identical simulataneously, merged some of the functionality and removed my module within less than a week
15:34 RabidGravy zengargoyle, yes
15:35 zengargoyle RabidGravy: cool, maybe i'll try and get my .so using module working again. :)
15:35 RabidGravy in fact it definitely does work as I properly fixed and tested Sys::Utmp and Sys::Lastlog yesterday

16:46 kyclark I'd like to understand the "so" operator:
16:46 lizmat cygx: how is that holding up with the spectest?
16:47 cygx lizmat: I'll write a test for it, then I can do a run
16:47 cygx I have no idea what my baseline is, though...
16:47 lizmat m: say ?(2 == <1 2 3>.any)    # kyclark
16:47 camelia rakudo-moar 947660: OUTPUT«True␤»
16:47 lizmat kyclark: aka a lower precedence version of prefix ?
16:48 kyclark It just forces a (Bool)?
16:48 psch kyclark: Bool coercion collapses Junctions into a single Bool value, yes
16:48 moritz kyclark:
16:48 lizmat m: say ?(2 == <1 2 3>.all)    # kyclark
16:48 camelia rakudo-moar 947660: OUTPUT«False␤»
16:48 kyclark lizmat, that helps
16:48 kyclark Is there a mnemonic for "so"?  Is it short for something?
16:49 ChristopherBotto kyclark: Imagine an argument between children: is not! is so! is not! is so!
16:49 n0tjack joined #perl6
16:50 ChristopherBotto kyclark: It is just the opposite of not
16:50 lizmat kyclark:  well, that is "so True"  :-)
16:51 hankache joined #perl6
16:52 kyclark One thing I love about the Haskell REPL is the ability to ask the type of an operator.  Is there any way to ask something like "so" what it takes and returns?  :t so  ???
16:52 psch kyclark: you can introspect the Signature of any Routine
16:53 psch well, Block, actually, but Routine isa Block
16:53 kyclark Ah, please tell me how!
16:53 AlexDaniel kyclark: you can also look at the docs

16:55 kyclark BTW, one rakudo I have prints "^[[A" when I hit the up arrow for the previous command, another works fine.  What do I need to do to fix that?
16:55 hoelzro kyclark: you could use rlwrap
16:55 hoelzro or install Linenoise
16:55 hoelzro MadcapJake: I think to add a command line switch, you'll need to look at src/main.nqp

17:01 lucs So, for a new module, .travis.yml,, or what? (any docs on that?)
17:01 AlexDaniel psch: though here it mentions that return type is Bool:D
17:01 AlexDaniel lucs: for sure, travis not required but recommended

17:02 Skarsnik
17:02 lucs Okay, will look, thanks :)
17:03 Skarsnik Something intesting could be to force travis to rebuild the ecosystem when doing a new release of rakudo

17:13 joeschome Hello
17:13 AlexDaniel hi!
17:13 RabidGravy nine, does anything do callwith in there?
17:13 ChristopherBotto Here's how private messaging camelia works, in case anyone is wondering (just don't leave any spaces at the beginning):
17:13 ChristopherBotto /msg camelia m: say so True
17:14 joeschome I am thinking of learning Rust & Perl6; do you think the two will work together well?
17:14 AlexDaniel you can also /notice camelia
17:15 nine $obj is an object of a runtime created class while self is the Perl6Callbacks object that's created only once. The only connection is that one of Perl6Callbacks' methods is in the call stack
17:16 lucs p6doc still uses @*INC ? :(
17:16 AlexDaniel joeschome: what do you mean by “will work together well”?
17:16 joeschome So what im thinnking is Rust would be good for low level and perl for more abstract
17:17 RabidGravy If Rust can make dynamic libraries it might work, though it doesn't appear to do anything Perl 6 can't
17:18 joeschome So maybe network concurancy and memory management in rust and string and file parsing in perl
17:18 dj_goku joeschome: I would suggest just trying both.
17:18 marchelzo joined #perl6
17:18 marchelzo hi
17:18 nine WTF? With method call_context() { note self.^name }; I get the wrong self, while with method call_context(\SELF:) { note SELF.^name } it's correct!
17:18 AlexDaniel joeschome: hm, interesting question. I think that if I were you I'd go C and Perl 6. The reason is that you can use NativeCall to call stuff written in C from Perl 6. Well, unless you can use NativeCall with Rust, I'm not sure
17:19 AlexDaniel marchelzo: hello!
17:19 nine I really start to suspect that there's a rakudobug to be found here
17:19 marchelzo is the MoarVM startup time going to get significantly faster, or is it bound to be slow?
17:19 AlexDaniel marchelzo: how slow it is for you?
17:19 tadzik hm, I honestly find it quite fast. How slow is it for you, and how do you measure it?
17:20 joeschome What im thinking is I know myself and I think rusts type safty will save me a lot of headache; however i love perl6 regex engine
17:20 marchelzo I haven't used it much, but from what I've read it's even worse than the JVM. I've heard it takes several seconds to start, rendering it useless for small command-line programs. It's making me hesitant to invest time into learning Perl 6, despite the fact that the language looks really interesting.
17:20 AlexDaniel marchelzo: look
17:21 AlexDaniel m: say 'hello world'
17:21 camelia rakudo-moar 947660: OUTPUT«hello world␤»
17:21 nine marchelzo: it's about 100ms here
17:21 dj_goku joeschome: doesn't perl6 have some type safety built in?
17:21 psch marchelzo: where'd you read MVM is slower than the JVM?
17:21 marchelzo Hmm... has it improved a lot recently?
17:21 dj_goku m: my Int $i = 'str';
17:21 camelia rakudo-moar 947660: OUTPUT«Type check failed in assignment to $i; expected Int but got Str␤  in block <unit> at /tmp/YqvjM7FyMO:1␤␤»
17:21 tadzik marchelzo: oh, you do read reddit, don't you? :)
17:21 AlexDaniel j: say 'hello world'
17:21 tadzik I saw that comment too, and contested it
17:21 camelia rakudo-jvm 6c0f93: OUTPUT«hello world␤»
17:21 joeschome Im sure it does so that brings me to my next question is perl6 better at systems programing that perl5
17:21 tadzik moarvm has always been MASSIVELY faster at startup than jvm
17:22 dj_goku joeschome: it is probably to early to say either way.
17:22 psch AlexDaniel: j: has nothing to do with jvm startup time, it's slow for all the other reasons r-j is slow :)
17:22 yqt joined #perl6
17:22 dj_goku joeschome: it is what you make it.
17:22 marchelzo I originially read it in this comment:
17:22 marchelzo But it looks like the author has editited it.
17:23 joeschome Ive always been under the "assumption" that perl is not ideal for systems programing.... I am willing to be wrong.
17:23 Skarsnik rakudo was slow without precomp with lot of module
17:23 nine joeschome: define systems programming
17:23 dj_goku joeschome: what do you mean by systems programming?
17:23 tadzik it still is with precomp and with a lot of modules
17:24 tadzik well, slower :)
17:24 marchelzo so what is rakudo? the compiler? it can emit jvm bytecode or moarvm bytecode?
17:24 tadzik yes
17:24 Skarsnik well I still hve a version without precomp and it's like 10-20 sec per launch with 4-5 modules xD
17:24 nine tadzik: now it takes some time to load a lot of modules. Previously it took lots of time with just having modules installed
17:24 tadzik oh, yes
17:24 tadzik correct
17:25 marchelzo ok. that's relieveing. where is the best place to learn perl6 from?
17:25 RabidGravy tadzik matey can I entice you to merge - I RT'd the cause but it may not get resolved very soon :)
17:25 tadzik oh, oh
17:26 tadzik absolutely :)
17:26 tadzik I should just add you to that project
17:26 RabidGravy cool, I'd like to encourage people to use Test::META which depends on it
17:26 RabidGravy :-*
17:27 nine Any opinions on renaming CompUnitRepo to CompUnit::Repository::Registry? I figure that's what it really is now: you can register types of CompUnit::Repositories with it and it gives you a CompUnit::Repository instance for a spec string.
17:27 jnthn nine: works for me
17:27 RabidGravy sounds fabulous :)
17:27 jnthn Though I'd probably drop the second ::
17:28 ChristopherBotto marchelzo: I'd recommend getting Rakudo Star here:
17:28 jnthn Because the Registry is not a type of CompUnit::Repository
17:28 nine jnthn: err...I actually meant RepositoryRegistry :)
17:28 lizmat nine: fine by me
17:28 jnthn hah! :)
17:28 jnthn nine++ # API design taste :)

17:28 jnthn Damn, nice!

17:28 jnthn Should fix that some day :)
17:29 Skarsnik Should I add support for .desktop format and windows registery in most wanted modules? x)
17:29 nine jnthn: oh yes :)
17:29 Skarsnik Could be useful to have perl6 that integrate well with a system

17:30 AlexDaniel joeschome: just what dj_goku said
17:30 dj_goku joeschome:
17:31 joeschome I think I am "believing" some  of the anti-Perl stuff about it only being a glue language or scripting language.
17:31 cygx t\spec\S17-supply\throttle.t hangs for me at 5/47
17:31 joeschome Personaly i love the syntax of perl
17:31 RabidGravy Skarsnik, I started working up the XDG spec but got blocked and only release the XDG::BaseDirectory
17:31 dj_goku joeschome: well it sounds like you have your answer. :D
17:31 joeschome Yeah
17:32 Skarsnik oh it's called xdg? I looked a bit to the format it look like .ini
17:32 ajs_ It seems that BUILDALL's return value is currently the return value of .new... is that intentional? Do we have to write our BUILDALL to return the invocant?
17:32 RabidGravy well it is an .ini type file yes, but the contents thereof are part of the XDG spec

17:34 Skarsnik RabidGravy, I wanted to add this a Config module (or something) to work like Qt::Config stuff. Where you register you app and it etheir write in windows registry or .desktop file on unix
17:34 joeschome So any idea when the perl6 "butterfly book" comes out; it looks like im going to need to buy it

17:52 hankache
17:52 joeschome It will probably take alot less time to write things in perl and if I can make reasonable responsive programs why not.
17:53 hankache That is still relevant even today.
17:53 nine .tell jnthn you'd never guess. It's a require Inline::Perl5 in the :lang<Perl5> EVAL candidate
17:53 yoleaux nine: I'll pass your message to jnthn.
17:54 AlexDaniel joeschome: by the way, do you have any previous programming experience?
17:54 joeschome a tiny bit of perl5
17:54 joeschome it was fun
17:54 Skarsnik joeschome, I think that depend a lot of what you want to do. writing a Gui not using something C#/.net or C++/Qt (or even C/Gtk) sound like a bad idea x)
17:55 marchelzo Is there any way to see documentation for a function or method within the perl6 repl? Like python's help() or something?
17:55 marchelzo Or at least list available methods on an object.
17:55 hankache Camelia will suck the brains of unrepentant grinches. I f*cking like this line
17:55 AlexDaniel marchelzo: $object.^methods

17:57 joeschome I think someone said you can do gtk in perl6
17:58 joeschome Im mainly a BSD/LINUX guy so thats fine with me
17:58 Skarsnik well you can use a part of gtk x)
17:58 marchelzo so, 'flat' basically forces an iterator/generator to produce a list? like list() in python.
17:59 xtreak joined #perl6
17:59 joeschome so what would you recomend for the GUI part
17:59 Skarsnik It the only thing available in perl6 for now so... gtk x)
17:59 dj_goku I have always wanted to write C++/Qt, but would be neat to do Perl6/Qt
18:00 timotimo i want that, too. but at the moment we have to go via Inline::Python to get Qt
18:00 Skarsnik Well feel free to write the smoke generator/binding
18:01 Skarsnik smoke is the tool used to generate C#, python/ruby/perl5 binding
18:01 Skarsnik for Qt
18:01 dj_goku timotimo: yeah I wondered if that is how we go it. wondereed how hard it would be to build an app.
18:02 timotimo Skarsnik: smoke is not used to create python bindings
18:02 timotimo Skarsnik: PyQt has SIP, PySide has Shiboken aka ApiExtractor/GeneratorRunner

18:05 timotimo Lylakudo Wars
18:05 joeschome I still use MC and Mp3blaster so a ncurses podcatcher in perl6 woudl be cool!
18:05 [Coke] marchelzo: there's more than one way to do it.
18:05 Skarsnik no idea. I came accross ~ or .Str
18:05 [Coke] I personally would use ~ unless I had a compelling reason to explicitly call .Str
18:06 Hotkeys There's more than one way to skin a cat
18:06 Skarsnik http::ua like .Str
18:06 marchelzo TMTOWTDI is still a thing in perl6?
18:06 lucs So should I just wait till after Christmas? I find it really hard to work without a module installer, a doc browser, and a debugger.
18:06 dj_goku marchelzo: why not?
18:06 RabidGravy marchelzo, very much so
18:06 xfix joined #perl6
18:07 Skarsnik lucs, fill an RT (or look it one already exists)
18:07 RabidGravy [Coke], my eyesight ain't so great so I prefer the more obvuos .Str ;-)
18:07 marchelzo I thought people agreed that 'There should be one-- and preferably only one --obvious way to do it.' was the better philosophy.
18:07 nine .tell jnthn I can lookup CompUnit::RepositoryRegistry at runtime. Seems like a small price for getting rid of it in the BOOTSTRAP
18:07 yoleaux nine: I'll pass your message to jnthn.
18:07 Hotkeys Which people
18:07 marchelzo People who bash perl5.

18:09 Hotkeys For one it isn't perl 6 :p
18:09 timotimo nah, python's good. lots of neat stuff to steal
18:09 marchelzo dj_goku: it is
18:09 El_Che I am looking on a way to serialize perl6 datastructures. I have big LDAP ldif that I read in order to convert into a data structure. While comparing these data structures I run out of memory (a 4gb VM). Is there native way to do serializing in p6? Use JSON::(Un)Marshal?
18:09 RabidGravy lucs, that warning is somewhat lower level and will go away when someone works out how to replicate
18:09 timotimo [Coke]: i bash perl5 sometimes
18:10 dj_goku I wouldn't mind an awesome REPL like ipython in perl6
18:10 timotimo dj_goku: then help arnsholt out
18:10 timotimo dj_goku: he's working on the iperl6 kernel
18:10 marchelzo Which type is used to represent a list of Int? I tried <1 2 3>.WHAT and it says Parcel.
18:10 [Coke] lucs: if you can't handle bleeding-edge, then yes, wait 2 weeks. But there's not going to be that many changes between now and then other than bugfixes and slight improvements. If you can report issues NOW, then hopefully we can fix them before the release on Christmas.
18:10 dj_goku timotimo: I have no idea where I would start. except at the beginning.
18:10 joeschome You guys have been super helpful: so my tentative idea is to learn perl6 by making an ncurses based pod-catcher. They say the best way to learn is to do a project. I listen to alot of podcasts (Twit and Jupiter broadcasting)
18:10 [Coke] timotimo: Mostly distinct.
18:10 El_Che dj_goku: :)
18:10 marchelzo Like if I wanted to write a routine to sum a list of Ints, what should its argument's type be?
18:10 [Coke] marchelzo: if you're getting parcel, you have an ANCIENT perl 6.
18:10 timotimo dj_goku: the good thing is that there's some code you can work upon
18:11 AlexDaniel marchelzo: it seems like your Perl 6 is old
18:11 [Coke] marchelzo: what does perl6 -v say ?
18:11 AlexDaniel m: say <1 2 3>.WHAT
18:11 camelia rakudo-moar 2f0d38: OUTPUT«(List)␤»
18:11 timotimo dj_goku:  -  have a look-see if you find it comprehensible
18:11 marchelzo [Coke]: what? I _just_ built it from source.
18:11 AlexDaniel marchelzo: it is List, as you might expect
18:11 dj_goku I have a module idea I want to start/build first.
18:11 [Coke] marchelzo: what does perl6 -v say?
18:11 joeschome You guys have been super helpful: so my tentative idea is to learn perl6 by making an ncurses based pod-catcher. They say the best way to learn is to do a project. I listen to alot of podcasts (Twit and Jupiter broadcasting). Do you think its  reasonable or crazy?
18:11 Skarsnik marchelzo, sub f(*@tab) (or just [+] if you want to sum a list)
18:11 marchelzo I downloaded the .tar.gz for 2015.11 but perl6 -v says 2015.03.
18:12 [Coke] I suspect you forgot to install and are running "perl6" instead of "./perl6"
18:12 vividsnow joined #perl6
18:12 dj_goku timotimo: oh great!
18:12 marchelzo ah, I was running the perl6 in /usr/local/bin.
18:12 AlexDaniel joeschome: it is 100% correct that you will learn by doing
18:12 [Coke] or perhaps installed it somewhere else.
18:12 marchelzo [Coke]: yeah, why doesn't make install put in in $PATH?
18:12 marchelzo put it in*
18:12 ajs_ m: class Foo does Iterator { has @.a handles "pull-one"; }; say
18:12 camelia rakudo-moar 2f0d38: OUTPUT«===SORRY!===␤Method 'pull-one' must be implemented by Foo because it is required by a role␤»
18:12 [Coke] you have to tell it where to install it.
18:12 Skarsnik rakudobrew does not install system wide
18:12 [Coke] there is a warning when you build.
18:12 marchelzo ah, I'll just move it.
18:13 Skarsnik that will not work probably
18:13 marchelzo why?
18:13 [Coke] perl --help will point you at --prefix, which is what you want.
18:13 Skarsnik some path are hardcoded like panda if I remember correctly
18:13 AlexDaniel marchelzo: so that you can install it in environments that you don't control
18:13 [Coke] I would reconfigure with the correct --prefix and then install.
18:13 marchelzo if I run into problems I will
18:14 AlexDaniel marchelzo: ah sorry, thought that “why?” was about not installing system wide
18:14 dj_goku I read a article recently say "we don't know anything as software developers/architect" we are just testing theories and learning from our mistakes. :D
18:14 marchelzo so <1 2 3> has type List. Is there no type called 'List of Int'?
18:14 timotimo dj_goku: you can only really learn from mistakes, fo course
18:15 timotimo marchelzo: you can get an array that's typed to contain only Int (or derived things, of course)
18:15 Skarsnik my Int @array;
18:15 geekosaur "if builders built buildings the way programmers write programs, the first woodpecker to come along would destroy civilization"
18:15 AlexDaniel m: my Int @a = <1 5 10>; say @a; say @a.WHAT
18:15 camelia rakudo-moar 2f0d38: OUTPUT«[1 5 10]␤(Array[Int])␤»
18:15 [Coke] m: my Int @stuff; @stuff.push("HI");
18:15 camelia rakudo-moar 2f0d38: OUTPUT«Type check failed in assignment to @stuff; expected Int but got Str␤  in block <unit> at /tmp/zl2KdpG6OO:1␤␤»
18:15 timotimo but if you have a sub like foo(Int @arr) { } you will not be able to call it with just [1 5 10], you'll have to give the type with it
18:15 marchelzo timotimo: which one is preferred. Like say I just want to do some computation with a bunch of Ints. Maybe sum them or compute their product or whatever.
18:15 marchelzo s/\./?/
18:16 [Coke] most of your questions about "which is preferred" are going to be "it depends".
18:16 timotimo if you have a bunch of ints, you can actually use "my int @arr", that'll give you 64bit ints
18:16 * lucs will rebuild rakudo/moar/nqp/panda from scratch for the umpteenth time and will see if panda still warns (like the last few times), if JSON::Fast still hangs (but knows how to work around), if p6doc still fails with @*INC, if the debugger still fails (after complaining of circular module loading).
18:16 marchelzo [Coke]: I know. I wish I could use other languages to make analogies.
18:17 [Coke] Also, in general, typing helps, but in the future, it will help more. (still more optimizations to come)
18:17 timotimo lucs: JSON::Fast doesn't hang any more. if it stlil does, tell me ASAP
18:17 Skarsnik sub foo(Int *@tab) {Do something with the array}
18:17 marchelzo vector<int> in C++ or [Int] in Haskell. like, the go-to simplest and most general way to represent a list of ints.
18:17 lucs timotimo: Okay, thanks.
18:17 timotimo fixed it like 3 days ago or so
18:17 lucs Oh, well, was failing last night :(
18:17 ajs_ So, is "handles" implemented currently? It doesn't seem to play well with composition.
18:18 timotimo whaaaaat? :(
18:18 lucs (commenting out line 153 in the first test fixes it iirc)
18:18 timotimo ajs_: can you supply a few test cases we could put into the spec tests to make sure the right semantics are covered for Christmas?
18:18 timotimo lucs: you may need to "git pull" in panda
18:18 marchelzo the 2015.11 perl6 wasn't built with readline :( is that something I had to configure as well?
18:18 ajs_ m: class Foo does Iterator { has @.a handles "pull-one"; }; say
18:18 camelia rakudo-moar 2f0d38: OUTPUT«===SORRY!===␤Method 'pull-one' must be implemented by Foo because it is required by a role␤»
18:18 ajs_ I don't think that would produce an error....
18:18 [Coke] ajs_: easiest way to get feedback on stuff like that is to make a gist with code that shows the behavior and describes the behavior youw ant.
18:18 timotimo marchelzo: not configure, just install the Linenoise module (you may need to use an earlier commit, though)
18:19 lucs timotimo: Like I said, I built from scratch (maybe I forgot something, going for it again).
18:19 [Coke] ... and I was too slow. Thakns. :)
18:19 AlexDaniel yeah, well, people can scream about only one way to do it right all day long, all I can say is that they can enjoy their crippled down functional programming (just because it didn't feel right to someone)…

18:54 Skarsnik well last commit is from 2-3 months for mi6 x)
18:54 timotimo zengargoyle: could very well be that mi6 doesn't know anything about RESOURCES yet
18:55 hoelzro I noticed this morning that panda will install anything under resources/ if resources isn't in; is that spec'd behavior, or just panda-specific?
18:55 hoelzro because I'm not sure how I should deal with liblinenoise.{so,dll,dylib} when I fix Linenoise =/
18:55 RabidGravy also blib is largely incompatible with the way that panda does a build
18:56 zengargoyle yeah, just letting peeps know since mi6 has been advertised a bit recently.  i've been using it for a while and it's been mostly OK.
18:56 zengargoyle it even worked for .so module pre-curli

19:11 tadzik what did this!?
19:11 tadzik can you even have directories with such names!?
19:11 zengargoyle lucs: hehe, saw that a few times.
19:11 lucs Oh, by the way, it appears that panda was installed nevertheless, but when installing a module, the "Use of uninitialized value %ENV of type Any in string context" still appears (but the module appears to be installed).
19:12 tadzik or is it just a stacktrace?
19:12 lucs tadzik: It's a directory hierarchy that was created under my panda/ directory when doing a
19:12 flussence joeschome: when people say perl6 is too slow, it almost always means they read an angry rant about an alpha version of it once five years ago, and are basing all their judgements off of that misinformation

19:12 lucs :)
19:13 geekosaur perfectly valid, if seizure-inducing, on unixlikes >.>
19:13 zengargoyle lucs, tadzik: i saw that from doing `mi6 build`
19:13 zengargoyle thought it was a mi6 problem...
19:13 tadzik mi6?
19:13 lucs It looks like some message that was redirected to path building instead of ERR or something.

19:14 nine amorphis++
19:14 zengargoyle so i'd guess it's coming from Panda::Builder or somesuch
19:14 tadzik lucs: alright, so the steps to reproduce is just 1) build rakudo somehow 2) clone panda 3) run
19:15 lucs tadzik: Apparently, yes.
19:15 tadzik and yours is a regular linux system?
19:15 lucs Let me try something first...
19:15 nine Got my brane going. Ginna replace %CUSTOM_LIB by a Compunit::RepositoryRegistry method.
19:15 vividsnow AlexDaniel: ok, sended
19:16 lucs tadzik: Yep, pretty much.
19:16 tadzik lucs: and you have no other rakudo/panda installations, due to rakudobrew or something?
19:17 lucs tadzik: Wait a sec, just thought of something...
19:17 jnthn is amazing :)
19:17 yoleaux 17:53Z <nine> jnthn: you'd never guess. It's a require Inline::Perl5 in the :lang<Perl5> EVAL candidate
19:17 yoleaux 18:07Z <nine> jnthn: I can lookup CompUnit::RepositoryRegistry at runtime. Seems like a small price for getting rid of it in the BOOTSTRAP
19:17 jnthn nine: +1
19:18 jnthn nine: Wait, you got to see amorphis too?! Darn. :)
19:18 lucs tadzik: (okay) Not as far as I can tell, no, I'll double check...
19:21 lucs tadzik: Everything looks kosher.
19:21 tadzik lucs: okay, will try to reproduce
19:22 retupmoca nine: could this be a cause of my panda bootstrap hang on windows?
19:22 lucs tadzik: Wait a sec.
19:23 lucs tadzik: Let me make really sure -- I'll reboot and try again -- better waste my time than yours.
19:23 tadzik I'm not sure that's true :P

19:27 nine retupmoca: could be. I have no idea about file locking semantics on Windows.

19:28 tadzik lucs: I honestly have no clue
19:28 lucs Yeah, not obvious eh :/
19:29 tadzik first gut feeling: some modules in panda return a Failure when they, well, fail
19:29 retupmoca nine: yeah, I only get hangs when I run 'perl6'. Sometimes I get errors about 'unable to write bytecode' from moarvm too, which makes it more confusing

20:28 lizmat if a list however contains containers, you *can* change a list
20:28 psch lucasb: i think the message is fine.  the Str is what's immutable, because Lists don't containerize

20:32 lizmat if you say "my @a = (...list...)"
20:32 lizmat you're effectively copying the list into an array, and thus it gets containerized

20:35 zengargoyle .tell RabidGravy your «ERL6LIB=blib/lib prove -v -r --exec=perl6 t/» isn't actually testing against blib, the «use lib 'lib';» in t/*.t are forcing it to use the .precomp in 'lib' instead.
20:35 yoleaux zengargoyle: I'll pass your message to RabidGravy.

20:37 geraud joined #perl6
20:37 psch hrm
20:37 RabidGravy zengargoyle, the thing is that the blib thing makes it difficult to test whether it will actually work installed, which I found by accident
20:37 psch what's happening with install paths anyway?
20:38 RabidGravy as "panda install" doesn't do blib
20:38 psch 0ec5ad56 was needed because make install installed the .jars into the wrong directory
20:38 zengargoyle yeah, it's a conundrum...  i usually don't 'use lib "lib"' in test files and i kept failing to find my library.
20:38 psch now when i'm trying make install now, i get complaints that the previous directory doesn't exist
20:38 zengargoyle no blib/resources/lib/
20:39 zengargoyle wait, panda install doesn't do the panda-build to blib and then copy from blib?
20:39 zengargoyle doesn't that break any sort of generated content?
20:41 Peter_R joined #perl6
20:41 RabidGravy if you generate into blib/... yes
20:41 RabidGravy which is how I found out
20:42 prevost joined #perl6
20:42 zengargoyle seems it should do a install to blib just like it would install to final destination, then test, then sorta re-install to final destination...
20:44 zengargoyle things would work better if panda-build also copied the resources like it does for the real install...
20:48 timotimo lucasb: can you locally golf the problem? because i can't reproduce it :(
20:49 * zengargoyle thinking best workaround for travis might be to install the module then prove the tests without any -I/PERL6LIBS setting.

21:18 RabidGravy or if it does I'd be surprised
21:18 marchelzo I don't know why it wasn't overwritted by the new install.

21:19 marchelzo Okay, when I run 'make install', I'm getting a lot of 'Can't exec "/usr/local/bin/bin/perl6-m"'.
21:19 marchelzo that path looks weird

21:22 RabidGravy timotimo, at some point people are going to want to do it though
21:22 marchelzo I know that would probably result in fewer issues, but for some reason I like all my installed binaries to be in /usr/local/bin.
21:22 timotimo (and sometimes i have to delete my whole prefix if some radical changes occur)
21:23 Skarsnik I use /opt x)
21:23 RabidGravy but yes while building several times a week or even a day it's a lot more sensible
21:24 RabidGravy my /usr/local is a different filesystem

21:31 timotimo .tell leont i would like to have a bit of help with Test::Harness at some point; moarvm is getting a line-based coverage reporting tool and reqiures to have an env var set; maybe something clever could be done in rakudo's t/harness?
21:31 yoleaux timotimo: I'll pass your message to leont.
21:31 RabidGravy mst, I was thinking about you and all that flooding, you escaped with your feet dry?
21:31 mst two of my three favourite pubs failed to float
21:32 mst the power was out for 48h
21:32 RabidGravy :(
21:32 mst I'm on the first floor -and- at the top of the hill, so the water was well away from me
21:32 marchelzo ugh.. now I'm getting errors building rakudo
21:32 marchelzo "Unhandled exception: Bytecode stream version too high"
21:32 hoelzro marchelzo: you probably have a MoarVM that's too old
21:32 leont o/
21:32 yoleaux 21:31Z <timotimo> leont: i would like to have a bit of help with Test::Harness at some point; moarvm is getting a line-based coverage reporting tool and reqiures to have an env var set; maybe something clever could be done in rakudo's t/harness?
21:32 timotimo mst: oh damn, that's tough :(
21:33 hoelzro so you'll have to checkout, build, and install MoarVM by hand
21:33 hoelzro same with NQP
21:33 marchelzo hoelzro: right before that it says: "Found /usr/local/bin/moar version 2015.11, which is new enough."
21:33 mst the area substation ended up under several feet of river
21:33 mst our power infrastructure is not quite designed for that
21:33 hoelzro I wonder if that's the actual moar it's using
21:33 jdv79 mst: where did all this water come from?
21:33 flussence the sky, mostly
21:33 lizmat jdv79: from above
21:33 mst we got a month's worth of rain in a day, and it splattered over all the hills as well
21:34 lizmat 300 mm of rain in a few hours, I've been led to understand
21:34 mst so anything near the river got a trifle soggy
21:34 * jnthn wonders if it's the same storm system that was causing some fun in Scandinavia at the weekend...
21:34 lizmat jnthn: pretty sure of that
21:34 mst it went across scandinavia then diagonally across scotland and down over us
21:34 marchelzo hoelzro: it's not T_T
21:34 flussence a few things here ended up underwater too, including a bus and most of the bridge it was on
21:34 lizmat it even had a name?  Patrick ?
21:34 mst I think
21:34 flussence (it was empty fortunately)
21:34 mst lizmat: DESMOND
21:35 marchelzo I though I removed all the 2015.03 stuff, but /usr/local/bin/moar was still a symlink to the homebrew rakudo install.
21:35 lizmat ah, oops
21:35 marchelzo thought*
21:35 hoelzro
21:35 lucasb The problem with installing things in /usr/local is that. You can't just simply delete a directory, you have to hunt those binaries...
21:35 marchelzo I really hope it works this time...
21:35 marchelzo lol
21:35 * mst usually installs into /usr/local/program-1.23/
21:35 mst and then symlinks things into /usr/local/bin
21:35 hoelzro this is why I install to $HOME/.mokudo, or better yet, /tmp/nom
21:41 leont timotimo: I'm not sure why you'd need the harness' assistence for that, I mean can't you just set it when running it? (probably missing something here)
21:42 Juerd lizmat: Yes, but not available for today and the next few days
21:42 leont Or do you want it to have a new value for every test file?
21:45 marchelzo I have no idea what I'm doing wrong.
21:45 marchelzo I configured with -prefix=/usr/local, but it didn't put perl6 or perl6-m in /usr/local/bin.
21:45 timotimo leont: i think it'd be good to have a separate value per test file, yeah
21:45 marchelzo So when I run 'sudo make install', it fails because it tries to use /usr/local/bin/perl6-m.
21:47 leont That would be tricky, in both implementations, it pretty much requires a custom source handler.

21:47 dalek roast: Fudge tests returning Int instead of Bool for JVM
21:47 dalek roast: review:
21:47 marchelzo It's installing it to ./install/bin/perl6. Is that normal even if you used a prefix like /usr/local?
21:47 timotimo leont: in that case, no problem. i'll just set a single value
21:47 leont Passing it a constant format (expanded with file name and process id) would probably be easier
21:48 timotimo leont: just ... how do i do that in perl5? :3
21:48 timotimo moar opens the given file in append mode, so it'll be all right
21:49 hoelzro marchelzo: I don't think so
21:49 hoelzro what is the exact command line you're calling with?
21:49 marchelzo perl --prefix=/usr/local --gen-moar
21:50 lucs Can I control (change) which directory is used for  ~/.perl6 ?
21:50 marchelzo it appears to execute successfully
21:51 marchelzo and when I run make install, it writes all kinds of stuff to /usr/local/share, so it must have recognized the prefix.
21:51 lucs (and what happens if I run perl6 from another $HOME?)
21:53 hoelzro hmm, that looks ok to me
21:53 leont append may or may not be atomic, it depends
21:53 timotimo yeah :(
21:54 timotimo i've noticed
21:54 timotimo i'll perhaps have to put in a mutex even for single-program cases
21:55 marchelzo do you think it would work if I just copied ./install/bin to /usr/local/bin?
21:56 ugexe no
21:56 marchelzo i tried it
21:58 marchelzo I think it worked
21:58 marchelzo it looks like it was trying to use /usr/local/bin/perl6 before having installed it.
21:59 marchelzo The very last thing that happens during a make install is 'Installing binaries for MoarVM'.

22:05 hoelzro I'm beginning to think the best next move for you, marchelzo, is to use rakudobrew
22:05 hoelzro that should (hopefully) straighten things out
22:05 marchelzo that's where I got the 2015.03 one
22:05 marchelzo I think...
22:06 timotimo rakudobrew doesn't support putting stuff outside of the /home at all, though
22:06 timotimo like, give it a --prefix and it will get quite confused
22:06 tadzik it's not supposed to accept a --prefix even :)
22:06 tadzik but it seems like quite a few people like rakudobrew as a build tool in general, rather than a "maintain installations in my homedir" tool
22:06 Skarsnik there is a --configure-option you can pass it --prefix
22:07 Skarsnik but yeah, it's not fun
22:07 tadzik I'd quite like to know the concrete usecases, maybe I can find some way for both of them to peacefully coexist. And, well, work
22:07 Skarsnik but git clone rakudo and running work

22:09 marchelzo does 'rakudobrew build moar' use git HEAD?
22:09 Skarsnik yes
22:09 tadzik I mean, if people want rakudo in a specific place, why go for rakudobrew
22:09 marchelzo I thought HEAD was not very good to follow right now?
22:10 lichtkind o/
22:10 tadzik you can ask rakudobrew to install a specific version
22:10 tadzik rakudobrew build moar 2015.11 for instance
22:10 tadzik it goes for HEAD by default
22:10 marchelzo to be honest, I just wanting a working perl6 repl with readline bindings
22:10 hoelzro I would recommend rakudobrew
22:10 jdv79 Skarsnik: you're not alone.  i've never used a repl or felt the need.
22:11 marchelzo if rakudobrew can give me that, I don't care if it's installed in HOME or not.
22:11 jdv79 i honestly do not comprehend it
22:11 tadzik what calculator do you use? :o
22:11 Skarsnik windows calc xD
22:12 jdv79 i mean from an interpreter like python or p6:|
22:12 jnthn Differnet people like to work in different ways. That's fine. It's Perl, there's more than one way to do it.

22:16 marchelzo that's something you should ask yourself, not me
22:16 Skarsnik I write code or execute stuff with -e to test thing lol
22:16 jdv79 marchelzo: ok
22:16 timotimo me, too, Skarsnik
22:16 ugexe i dont use the repl either, but probably because im too stuborn to learn a new way to code
22:17 marchelzo I haven't used the perl6 repl very much, maybe it isn't great, but I've used good repls and they really are helpful.
22:17 jdv79 the natural progression for me is one liner and then to a test file.  idk.
22:17 ugexe me too
22:17 hankache for some people repl can be helpful
22:17 * jnthn finds having a window with the REPL open kinda useful when teaching
22:17 hankache it's not one size fit all
22:17 RabidGravy yea, I'm in the -e or test file camp
22:18 jnthn 'cus it lets you show stuff without the ceremony of doing -e, and it auto-prints expressions

22:23 hankache congrats marchelzo
22:23 hoelzro marchelzo: did you install rakudo from git HEAD?
22:23 hoelzro or 2015.11?
22:23 Juerd hankache: Perl has no official IRC channel, but there are multiple channels about Perl
22:23 marchelzo git HEAD I believe (I just did rakudobrew build moar).
22:24 hoelzro marchelzo: then you'll need Linenoise HEAD
22:24 marchelzo oh, right
22:24 [Coke] ... oh my! we're going to beat Half Life 3.
22:24 hankache Juerd which one is the equivalent of this?
22:24 hoelzro you'll probably need to --force install it
22:25 marchelzo hoelzro: FINALLY!
22:25 hoelzro \o/
22:25 Juerd hankache: There is no equivalent. Perl is literally older than IRC and the channels just co-exist.
22:26 marchelzo hoelzro: timotimo: thanks for all the help
22:26 marchelzo anyone else who helped too
22:26 hoelzro no problem

22:28 marchelzo it's ok

22:28 Juerd Might be a timezone thing
22:28 hankache ah! the freenode one showed a sign of life
22:29 marchelzo ok so <1 2 3> has type List, but <3> has type IntStr. What's with that?

22:37 Juerd It's everyone's favourite debug tool, so it deserves a nice and short name.
22:38 marchelzo what's the difference between an Array and a List?
22:38 Juerd Arrays are mutable
22:38 hankache m: my $a = 42; say $a.perl;
22:38 camelia rakudo-moar 96bc43: OUTPUT«42␤»
22:38 marchelzo Juerd: Is that the only difference?
22:39 Juerd I'm not sure
22:39 jnthn Arrays can also be typed, and shaped, or typed and shaped (including native types to provide packed storage)
22:39 hankache i see dd can be more useful than .perl sometimes
22:39 hankache thanks lizmat Juerd
22:39 hankache thanks jnthn
22:40 lizmat Juerd: also, if an element of a List is a container, it *can* be changed
22:40 lizmat m: my $a = (1, my $ = 2, 3); $a[1] = 42; dd $a
22:40 camelia rakudo-moar 96bc43: OUTPUT«List $var = $(1, 42, 3)␤»
22:40 jnthn Generally, arrays are used for mutable storage, lists are often more transient
22:41 Juerd lizmat: Sure, but the elements are not the List
22:41 marchelzo lizmat: well that is consistent with Lists being immutable
22:42 lizmat well, some people interpret "List are immutable" as the values in a List being immutable as well
22:42 jnthn Right, nothing stops an immutable list containing mutable objects.
22:42 lizmat I wanted to get that across  :-)
22:42 jnthn Yes, it's an important distinction :)
22:43 * hankache still doesn't fully understand who is mutable and who is not
22:43 timotimo jnthn: - did you see this? it hangs after a while of running :(
22:44 * hankache and how to know if a function is a mutator or requires .=
22:44 jnthn timotimo: No, but is it another case of that concurrent GC issue?
22:44 jnthn hankache: It's probably easier to assume "not mutating" in Perl 6 and learn the things that do mutate.
22:45 jnthn Most things don't.
22:45 hankache ok
22:46 hankache what about functions and mutators
22:46 hankache .pop vs .sort
22:46 Juerd What about them?
22:46 El_Che jnthn: it's not very concurrent
22:47 jnthn El_Che: Waht isn't?
22:47 El_Che timotimo's linkk
22:47 hankache .pop modifies the array
22:47 hankache .sort doesn't
22:47 zengargoyle hankache: i think that.. scalar containers do a good job at being invisible ... helps a bit.
22:48 hankache and so if you want to store the array and store it sorted you use .= instead of=
22:48 zengargoyle as in there's sometimes a scalar container there (just like there could be an array container there) except the scalar container often tried to hide that it's there.
22:49 lizmat El_Che: how can $closed ever be true if it doesn't get updated inside the loop ?
22:49 lizmat until $channel.closed {
22:49 jnthn Yes, push/pop/shift/unshift/splice are some of the handful that mutate, mostly becuase they'd be a heck of a lot less useful if they didn't.
22:49 lizmat would make more sens to me
22:50 jnthn lizmat: It's a Promise
22:50 timotimo jnthn: it doesn't happen in GC, nah
22:50 lizmat ah, ok
22:50 jnthn timotimo: How long does it take to hang?
22:50 timotimo usually does so well within a single minute
22:50 jnthn I'm up to 170 iteratoins here
22:51 TimToady m: [&&] 0, say("oops")
22:51 camelia rakudo-moar 96bc43: OUTPUT«oops␤»

22:51 timotimo got it to hang, will give you backtraces
22:51 jnthn OK. I'm up to like 230 now :)
22:51 jnthn it's warming my room up too :P
22:52 timotimo
22:52 Juerd TimToady: Oops indeed :)
22:52 timotimo i tried to get gdb to go to a certain frame and print the moar-level backtrace with "thread apply all", but it seems to only take a single command argument :(
22:52 hankache thanks zengargoyle
22:53 El_Che lizmat: close would be true when the channel is empty?
22:53 timotimo jnthn: the "shift" invocations were both in scheduler's "maybe_start_thread" looking for new work to enter the queue
22:53 TimToady m: [xor] 1, 1, say("oops")
22:53 camelia rakudo-moar c27a00: ( no output )
22:53 TimToady m: [xor] 1, say("oops")
22:53 camelia rakudo-moar c27a00: OUTPUT«oops␤»
22:54 jnthn The condvar wait is almost certainly going in Promise
22:54 TimToady m: [or] 1, say("oops")
22:54 hankache jnthn: i agree but as an end-user is there a way i can now beforehand who mutates and who doesn't?
22:54 camelia rakudo-moar c27a00: ( no output )
22:54 hankache know**
22:54 jnthn hankache: Read the documentation? :)
22:55 hankache fair enough
22:55 jnthn hankache: Generally though, we can't actually make everything mutate or everything not mutate and end up with, well, a Perl :)
22:56 jnthn So we generally lean fairly strongly towards not mutating, except when the forces push against it.
22:56 jnthn One guideline is "if this didn't mutate, would it be algorithmically more complex"?
22:57 crux joined #perl6
22:57 timotimo jnthn: at least Thread 5 is inside promises .result under status == Planned
22:57 jnthn But that's probably a bit fraught :)
22:58 jnthn hankache: You never have to wonder on value types (all the numeric types, Str, and List, for instance), because those cannot mutate
22:58 jnthn hankache: Similarly for anything you can do on a Supply or a Seq, which are all based around buiding up pipelines of operations.
22:58 timotimo jnthn: paste updated with the MVM_dump_backtrace results
22:58 jnthn Date/time stuff also works like immutable values
22:59 jnthn So generally it's only the mutable things - like Array/Hash/SetHash/BagHash/MixHash - where it's a consideration.
22:59 hankache i see
23:00 * hankache will sleep less ignorant tonight
23:00 El_Che lizmat: compare the channel->poll code with the channel react code. The code is in the same place: vs
23:01 El_Che and it's a Promise indeed
23:01 El_Che I mean, "the close is in the same place"
23:01 hankache thanks jnthn
23:02 jnthn :)
23:02 jnthn timotimo: heh, I'm up to like 900 here by now ;)
23:02 El_Che If we need to check for the channel.close status with react, there isn't much syntatic added value compared to the channel.poll way
23:03 _nadim hi, is transliteration documented somewhere? returnss nothing for tr trans transliteration
23:03 jnthn El_Che: Why do you need to check for that with react/whenever?
23:04 jnthn El_Che: If you want to do something when the channel is closed, use a LAST { ... } block inside the whenever.
23:04 jnthn (Which will trigger after you already processed the last actual value from the Channel)
23:04 Juerd _nadim:
23:04 El_Che jnthn: it just needs to get out of the react block once the channel is closed
23:04 timotimo jnthn: so maybe it's a linux-only thing? :\
23:05 jnthn El_Che: Do you have any other whenevers in the react block?
23:05 El_Che no
23:05 jnthn Then that'll happen automatically
23:05 El_Che jnthn: in 5% of the time it just hangs
23:05 timotimo helgrind, a thread error detector
23:06 El_Che jnthn: put the bug here:
23:06 timotimo much output
23:06 lucs This appears to work, but is there something more idiomatic?:  use lib$?FILE).dirname;
23:06 jnthn El_Che: Yes, I suspect there's a data race somewhere. The "use a Channel in a react block" code is just a few days old.
23:06 _nadim Juerd: thanks but the docuentation doesn't list the. I'll test it
23:06 timotimo ok, now it's hanging
23:06 El_Che in short: 1. I don't get the doc (I'll patch it accordingly when I get it)
23:07 Juerd _nadim: Documentation is missing for a lot of things. Maybe you'd like to write some? :)
23:07 masak "When invoking cuid_7_1449615985.11669 '', provided outer frame 0x59ec270 (cuid_25_1449615985.11669 'install') does not match expected static frame 0x47a02a0 (cuid_12_1449615985.11669 '')"
23:07 jnthn timotimo: It's not immediately clear to me what's to blame from the backtraces
23:07 masak is a bit of a funny error message
23:07 masak is this related to precomp?
23:07 El_Che 2. There is a bug, but there is a valid not much shorter way to do the same -> if it doesn't stabilize, just re-add it after xmas?
23:07 masak should I blow my lib/.precomp/ ?
23:08 timotimo jnthn: F5 on the gist gives you the exact script i ran and helgrind output
23:08 jnthn El_Che: I'm not too worried about bugs in xmas of the "it obviously fails to work right" nature
23:08 jnthn El_Che: I'm worried about "it works wrong and you can end up depending on semantics we don't want"
23:08 timotimo especially the very end might be good, the "at exit, thread #foo was still holding $n locks: ..."
23:08 masak hm, blowing lib/.precomp didn't help
23:08 timotimo jnthn: i suppose it can wait, then :)
23:08 masak I'm now thinking I've actually done something Very Bad in my code...
23:08 jnthn masak: It's one of those "should never really happen" things
23:09 jnthn masak: Last time I saw it, it was because of a nasty data race
23:09 El_Che jnthn: I get the stylish feel of the react syntax (that why I converted my code and hit the bug), but I don't think the channel poll is bad. On the contrary
23:09 jnthn But that was fixed months ago, and I've never seen it again since.
23:09 El_Che very straight forward: a closed promise + poll
23:09 _nadim Juerd: Getting to the point I can help, rigt now I am writting my first lines of P6
23:09 jnthn El_Che: Yes, it's nice the long way around is still not that long :)
23:10 jnthn We'll get to the bottom of what's going on with the react thing
23:10 masak jnthn: suspected the "should never happen" thing
23:10 _nadim I would have expected the methods to be auto generate in the docs, I guess they are, but trans is missing
23:10 masak not sure what I've done yet, but it's nothing to do with data races
23:10 timotimo the only thing i can come up with: $lock.protect doesn't work :P
23:10 jnthn I just need a decent stretch of time to look at them when I'm not tired, and those aren't available for another couple of days. :)
23:10 El_Che jnthn: what a like about the poll thing that it stays in the channel mindset instead of putting you on a supply mindset, imho
23:10 Juerd _nadim: That's cool. I hope you're having fun with your first lines :)
23:11 Juerd _nadim: Docs are not auto-generated (yet?)
23:11 jnthn El_Che: react/whenever work on Promise also
23:11 jnthn El_Che: So they're pretty cross-mindset :)
23:11 jnthn El_Che: The real power is you can use supplies *and* channels in the same react
23:12 _nadim I've had nightmares but fun. I am putting tests in my first module, I should get there before Christmas ;)
23:12 _nadim Hu! not autogenerated!!!!
23:12 El_Che anyway (and unrelated), whoever added the nl-in in IO::Handle recently: You sir or madam, made my code a lot faster. Kudos
23:12 _nadim I need to find time indeed
23:12 Juerd _nadim: Documentation is mostly written separate from the spec and implementation, at
23:12 jnthn El_Che: So, process data coming back from a worker on a channel while looking out for a SIGINT when somebody wants to stop the work, or so :)
23:13 masak good news -- I got rid of the Very Bad thing, and I now know what I did that was Very Bad, and I'll probably be able to produce a rakudobug from it :>
23:13 jnthn masak: Did it involve BEGIN time? :)
23:13 cdg joined #perl6
23:13 timotimo El_Che: nl-in and nl-out moved into the VM in big parts; especially chomping is there now
23:13 jnthn Only nl-in moved into the VM :)
23:14 El_Che jnthn: I process big LDAP ldif (the complete db dump). Now that I can split by records (separated by an empty line) instead of line, everything is easier (e.g. line continuations, etc)
23:14 timotimo oh, right
23:14 jnthn It learned to support multiple, and multi-char, separators at the same time.
23:14 timotimo well, that's the more expensive one anyway :)
23:14 _nadim Juerd: you're sure that's the right url?
23:14 jnthn And to directly construct the correct string, rather than the unchomped one and then substringing it.
23:14 TimToady m: say (say("oops") !R&& 0)
23:14 camelia rakudo-moar c27a00: OUTPUT«True␤»
23:14 TimToady m: say (say("oops") !RRR&& 0)
23:14 camelia rakudo-moar c27a00: OUTPUT«True␤»
23:14 TimToady m: say (say("oops") ![!RRR&&] 0)
23:14 camelia rakudo-moar c27a00: OUTPUT«False␤»
23:14 jnthn o.O
23:14 El_Che timotimo: before the move, using "\n\n" didn't work as a separator, only "\n", "\r\n" and whatever random char :)
23:15 jnthn timotimo: Show-off! :)
23:15 jnthn uh
23:15 jnthn TimToady: Show-off! :)
23:15 donaldh With the new precompilation code, is -I ignored ?
23:15 TimToady ayup :)
23:15 nine Woah...I just stumbled over panda's DepTracker. It's a wonder this thing still works after curli got merged
23:15 jnthn I guess that's another RT down? :)
23:15 nine donaldh: nope
23:16 Juerd _nadim: No, but why would it be the wrong url? :)
23:16 El_Che going to bed. Have fun hacking!
23:16 donaldh I compile a module with --target=jar
23:16 donaldh Then I use module, but it goes and precompiles the module.
23:17 Juerd El_Che: Good night
23:17 timotimo nine: um, does DepTracker even still get used? i don't think so, actually
23:17 lizmat good night, El_Che
23:17 donaldh Is that expected?
23:18 _nadim Juerd: because I tried to clone it rather than open it ;)
23:18 Juerd _nadim: Oh, for cloning remove the last part of the path :D
23:18 _nadim it's cloned already ;)
23:19 Juerd Oh no!
23:19 nine timotimo: oh...then I'll just remove it and see if anything breaks
23:20 timotimo i think it went away when panda kicked out precomp
23:20 timotimo i mean ... became unused
23:20 donaldh nine: I'm trying to debug the "Missing serialize function for REPR ContextRef" JVM bug.
23:20 nine donaldh: any progress?
23:21 nine donaldh: or actually: is it still there?
23:21 donaldh When a module uses another module, it fails to serialize
23:22 donaldh When trying to serialize a CompUnit::Handle
23:22 marchelzo hyper operators are weird as fuck
23:23 marchelzo $a R+= $b
23:23 donaldh nine: yes it's still there as of earlier today
23:23 nine donaldh: 75ca9dcbb495763a2fb9e9f4829b9ba885db2a8e was an attempt to fix that, but it broke the spectests spectacutlarily
23:23 TimToady m: 42 R[+=] my $b; say $b
23:23 camelia rakudo-moar c27a00: OUTPUT«42␤»
23:24 TimToady m: 42 R+= my $b; say $b
23:24 camelia rakudo-moar c27a00: OUTPUT«42␤»
23:26 marchelzo imagine if there were something like IOCCC for perl6
23:26 marchelzo this language is the quirkiest thing I've ever encountered.
23:26 nine donaldh: I guess it broke exactly when a module uses another module
23:27 donaldh hmmm, reading diff
23:27 timotimo i'll go have a sleep
23:27 nine good night timotimo++
23:27 nine timotimo: thanks for the hint about DepTracker :)
23:27 timotimo sure thing! :)
23:27 arnsholt marchelzo: R[op] isn't even a hyperop, that's just a metaop ^_^
23:28 timotimo yeah, that's how we do bracketing inside metaops
23:28 timotimo if things get ambiguous, you can disambiguate
23:28 marchelzo arnsholt: what's a hyperop? Is >> << a hyperop?
23:28 timotimo but does R[[op]] work as a reduction operator?
23:28 timotimo marchelzo: >> << on its own isn't. together with other things it is
23:28 marchelzo I see
23:28 TimToady [] is reduction only when used as a listop
23:29 M-Illandan joined #perl6
23:29 TimToady otherwise it's just disambiguation
23:29 timotimo hm, OK
23:30 * TimToady suspects that hyperops should *not* pay attention to thunking, since they are built to work on single items with internal structure, rather than comma lists
23:30 pippo left #perl6
23:32 timotimo so no >>andthen<< any time soon? ;)
23:32 * timotimo disappears towards bed
23:32 TimToady use Zandthen if you want that
23:33 bookimp joined #perl6
23:36 marchelzo what is .? is it an operator?
23:36 marchelzo or is it syntax?
23:36 TimToady in a method call?
23:37 TimToady it's a variant of . that doesn't blow up if the method doesn't exist
23:37 TimToady m: say 42.nonesuch
23:37 camelia rakudo-moar c27a00: OUTPUT«Method 'nonesuch' not found for invocant of class 'Int'␤  in block <unit> at /tmp/KbMAmAKHBp:1␤␤»
23:37 TimToady m: say 42.?nonesuch
23:37 camelia rakudo-moar c27a00: OUTPUT«Nil␤»
23:37 marchelzo sorry, the question mark was indicating a question
23:37 marchelzo I meant just the dot
23:37 TimToady ah
23:37 TimToady dot in which context?
23:37 marchelzo like 4.sin
23:37 TimToady just means you're calling a method
23:37 TimToady was -> in Perl 5
23:37 marchelzo so it's syntax?
23:38 TimToady yes, it's really sort of a postfix prefix :)
23:38 TimToady in fact, you can take any non-method postfix and add a .
23:38 marchelzo I thought something like: [1, 2, 3] >>.>> sin would work.
23:38 marchelzo but that would require . to be an operator.
