cpan-p6 New module released to CPAN! FindBin::libs (0.0.1) by 03LEMBARK 00:46
swissChili Hey folks, I'm trying to learn perl6 again, I've used perl5 estensively but am fairly new to perl6. How can I check if a file exists in p6? 03:40
I've looked on the subroutine docs and can't find anything 03:41
sjn m: say "/etc".IO.e 03:42
camelia True
sjn it's an IO method 03:43
m: say "/etc/example".IO.e
camelia False
sjn swissChili: docs at doc.perl6.org/routine/e 03:44
a good place to start when you already know Perl 5 is to check out the migration guides at doc.perl6.org/language.html 03:46
swissChili great, thank you so much! 03:48
From what I gather perl style flags (-e, -m, etc) aren't a thing in p6, is that correct?

timotimo kawaii: is the discord irc bot sick? 17:13
kawaii timotimo: uh not sure, I didn't create/maintain it sorry! 17:14
timotimo your name just came to mind when i thought "discord" :P 17:15
timotimo oh, it's tyil who runs it, isn't it? 17:15
AlexDaniel maettu, rba: ↑ 17:18
another thing you should be aware of :)
timotimo ah, good point 17:19
sena_kun is github.com/perl-gsoc-2019/ideas/bl...linking.md accepted, right? and it means an ability to ship a single binary, right? 17:41
lizmat yes, I think that is indeed the goal 17:43
sena_kun thanks 17:44
rba Hmm. What is the discord irc bot? 17:50
jmerelo sena_kun: yep. It's now in the community bonding phase, but I'm not sure how they are doing. 17:51
MasterDuke sena_kun, jmerelo: they're discussing in #moarvm right now 17:52
jmerelo MasterDuke: great
MasterDuke rba: bridges the discord room and this channel 17:52
jmerelo Thanks!
sena_kun jmerelo, I see, so that's what I thought. Just got asked by a friend, "Can Perl 6 give binaries?" and I responded with "There is a gsoc project doing this year", but then wanted to re-confirm I am right. :) 17:53
s/this/this this/ 17:54
MasterDuke sena_kun: i think samcv did something with flatpak already and jnthn has App::Wix for windows if they don't mind big files 17:54
samcv yeah there is some flatpak thing. i think somebody else did it better though 17:55
samcv not sure. otherwise ask me and i'll show you my repo. 17:55
samcv did we fix the issue that perl 6 can't be relocated yet? 17:55
sena_kun I think "yes" 17:56
MasterDuke yeah
samcv ok. then yeah. my package works but can be simplified now :)
maybe why it's failing the build. in addition to maybe other things. i used to have to use sed on binary files to change the directory :)
kawaii timotimo: ah, no it's the API::Discord module I maintain :)
samcv so now it's muchhh easier to do :)
sena_kun I told there are docket images available, so it is probably enough
*docker
samcv yeah. my appimage is not production ready anyway. modules were. weird 17:57
random module breakyness
can't install modules etc
timotimo samcv: wasn't that AppImage? 18:06
ah, you also mentioned those
samcv yep 18:13
kawaii It'd be interesting to see Java binaries to run Perl 6 code, I expect something is possible with the JVM backend. 19:08
antoniogamiz can someone tell me difference between when :(Pod::FormattingCode $) and :("",Pod::FormattingCode $,"") 19:53
?
sena_kun antoniogamiz, where is this from?
antoniogamiz htmlify 19:54
there's a comment that says # XXX: Remove when extra "" have been purged 19:55
sena_kun both are signatures, first one takes a Pod::FormattingCode object(though leaves it anonymous), the second takes three arguments, two are constant empty strings, in between there is a Pod::FormattingCode.
m: sub foo("", Int $_, "") { say $_ }; foo('', 42, '') 19:56
camelia 42
sena_kun m: sub foo("", Int $_, "") { say $_ }; foo('', 42)
camelia Too few positionals passed; expected 3 arguments but got 2
in sub foo at <tmp> line 1
in block <unit> at <tmp> line 1
sena_kun m: sub foo("", Int $_, "") { say $_ }; foo('', 42, 'bar')
camelia Constraint type check failed in binding to parameter '<anon>'; expected "" but got "bar"
in sub foo at <tmp> line 1
in block <unit> at <tmp> line 1
sena_kun so it enforces a call like `'', $code, ''`, though I don't have an idea for what it can be necessary, you can be interested in taking a look at callers 19:57
antoniogamiz that happens a lot in htmilify xdd
thanks sena_kun
sena_kun I don't know what you are doing, I would just look at recent attempts to rewrite the whole thing from scratch... but that's just me. good luck, anyway. 19:59
s/doing, /doing, but / 20:00
antoniogamiz I'm trying to understand how definitions are made
sena_kun would stick a `say $_` at github.com/perl6/doc/blob/master/h...fy.p6#L570 and something like `say normal`, `say a thing with weird "" around` in `when` blocks, and then run the thing to see what it prints out and what items go into ("", Pod::FormattingCode $, ""), and what items go into :(Pod::FormattingCode $), once you can figure the difference in input, you can think of what to do with it. 20:03
antoniogamiz sena_kun: yep, I will do that :) 20:07
this is also to build tests and move that logic to Perl6::Documentable
sena_kun but it somehow seems very unidiomatic for me, so ++antoniogamiz if you will be able to get rid of it. ;) 20:08
antoniogamiz first I have to untagle it haha 20:09
sena_kun yes, that's for sure
antoniogamiz surprise, that case does not even run in the full set docs 20:20
sena_kun .oO ( rip and tear, rip and tear ) 20:21
antoniogamiz :D
MasterDuke kawaii: the truffle branch of nqp can make binaries with graalvm that start instantly 20:27
antoniogamiz use say everywhere is the best debugger :D 20:39
sena_kun I remember Comma to be unable to parse htmlify, not sure if it is so today 20:40
antoniogamiz Comma? 20:41
sena_kun commaide.com/
antoniogamiz uoh :oo 20:42
sena_kun yes, unfortunately, it cannot process htmlify.p6 as it is now. :/
antoniogamiz for the moment :D 20:43
sena_kun yup
jnthn sena_kun: Hm, why not? 20:44
sena_kun jnthn, it fails to parse it in multiple places
for example, `=begin` with an indentation, `>>` operation in an expression(which is a hard one) 20:45
kawaii I should probably update my Comma, still using the release version 20:46
sena_kun kawaii, hmm, what release? 20:47
kawaii sena_kun: like the first public release of the community edition 20:47
jnthn Ah, then yes, there is a newer community one than that. :)
sena_kun and it fixes a number of bugs 20:48
kawaii can I just overwrite the files with the files from the new tarball? 20:49
sena_kun better to put it in the sibling directory, and once you migrate, you can just remove the old one 20:50
jnthn sena_kun: Will see if I can figure out any of the htmlify.p6 issues...at least when I'm not distracting myself with $shiny-new-feature :) 20:51
sena_kun jnthn, good luck.
jnthn heh, for the =begin identation one and my recollection of the grammar there, "good luck" is indeed useful :)
sena_kun this way, I hope a grahical debugger will be helpful for antoniogamiz to hack on docs. ;) 20:52
antoniogamiz :) 20:54
uzl Hello #perl6! 20:56
sena_kun o/
timotimo greetings uzl
uzl So do I pass an array of values to a MAIN with an array signature? 20:57
uzl greetings, sena_kun and timotimo! 20:57
antoniogamiz o/
AlexDaniel uzl: you mean like, properly? I don't think it actually works, but if you have sub MAIN(:@foo) you can then do --foo=42 --foo=43 20:58
it only works if you have zero, two or more elements 20:59
MasterDuke hm, didn't someone say they were going to work on that recently 21:00
uzl AlexDaniel: Oh, I see! Do you think a similar behavior will ever be part of Rakudo? 21:00
AlexDaniel uzl: it's already part of rakudo, it just doesn't work if you only pass one argument 21:01
AlexDaniel ah wait 21:01
github.com/rakudo/rakudo/issues/2797
according to this ticket, it was recently fixed
so lizmat++ and feel free to use it :) 21:02
uzl BTW, what does the '<foo>' symbolizes in the usage message? A list of values?
kawaii sena_kun: wow, Comma detected my previous installation and asked if I wanted to import my settings :O 21:03
sena_kun kawaii, well, it is based on IntelliJ, and IntelliJ does that. ;)
AlexDaniel uzl: it doesn't symbolize anything I think, IMO it should say foo instead of <foo> 21:04
sena_kun so you don't want to overwrite anything, really, just enough to get a new one, import settings, possibly remove the old one if you want, and get back to work with new features. :]
MasterDuke sena_kun: do i need any additional plugins to also use comma for c (moarvm) development?
AlexDaniel uzl: although, if you have something like `sub MAIN(‘foo’)` 21:04
uzl: then it'll be foo instead of <foo>
uzl: man git seems to use a similar notation 21:06
where fixed strings like subcommands are shown as is and everything else is in <>
sena_kun MasterDuke, do we have a lot of Perl 6 code in moarvm? If it is (almost) pure C, then I'd take something that you are using usually.
MasterDuke sena_kun: not a lot of perl 6 code. i mean to use comma for the pure c 21:07
sena_kun MasterDuke, no, Comma is a Perl 6 IDE. You can try out CLion, which is based on IntelliJ as Comma is. 21:08
uzl AlexDaniel: Thanks for the explanation. I just noticed that the foo example in the issues uses a named array but I'm trying with a positional (e.g, sub MAIN(@foo) { ... }). 21:10
Is it possible to use a positional instead?
AlexDaniel uzl: yes, just has to be *@foo 21:10
uzl Oh, great! Thanks. The reason why it needs the '*' is the same reason why one would use in a regular subroutine right? 21:13
I mean... for the slurpy behavior.
AlexDaniel uzl: I guess, but it makes me wonder why `sub MAIN(@foo)` works at all 21:15
shouldn't it complain or something?
uzl It doesn't work on my end! That's why I was struggling with it ;-)! 21:17
nadim_ I have a sub that returna Str but I want it to return a variable container. how does one do that?
uzl It prints out the usage message.
uzl nadim_: return-rw? 21:17
nadim_ ah, right! 21:18
uzl nadim_: docs.perl6.org/syntax/%20return-rw
nadim_ I read about it yesterday :) memory is not so goodany longer 21:18
but what if one wants to return some variables as rw and other ro? 21:19
uzl I'm not a 100% sure but wouldn't using just `return` returns a value which means it's ro since it cannot be mutated? 21:21
Or do you mean returning both from the same subroutine?
nadim_ returning both 21:22
uzl Sorry but I'm not sure :(! 21:23
nadim_ no problem ;) 21:23
AlexDaniel uzl: this works for me: perl6 -e 'sub MAIN(*@foo) { dd @foo }' foo bar baz
e: run <perl6 -e>, ｢sub MAIN(*@foo) { dd @foo }｣, <foo bar baz> 21:24
evalable6 Array element = ["foo", "bar", "baz"]
AlexDaniel uzl: oh, you mean with just @foo? Yeah… 21:24
doesn't complain and doesn't work 21:25
uzl AlexDaniel: Yeah, it works for me too. I was just confirming that without the *, the usage message is printed.
with just @foo
So I guess it's working as expected
