WRSomsky I was wondering: Can the current rakudo compiler (2019.11) be dropped into rakudo-star 2019.03? Mostly wondering for getting a jump on the Perl6 -> Raku renaming... 00:42
AlexDaniel WRSomsky: I'm curious, why do you use star? :)
WRSomsky Thought that was the way to get the appropriate libraries/modules/etc. 00:43
vrurg wonders if RakudoStart makes any sense in the light of rakudobrew existance. 00:44
cpan-raku New module released to CPAN! LibXML (0.2.1) by 03WARRINGD
Kaiepi just uploaded a new module that will be of interest of anyone working with the MOP :) 00:49
AlexDaniel WRSomsky: you can just install modules that you need with zef 00:50
Star is probably useful on Windows, but everywhere else you can probably do without 00:51
WRSomsky Ah. I've been using perl5 for years, but only glanced at perl6/6lrep/raku so far. 00:52

Doc_Holliwould stack-exchange code review doesn't know about raku yet 01:23
i had to post under "perl6" 01:24
i dont have enough rep there to create a new tag
codereview.stackexchange.com/quest...e-knapsack if someone is bored 01:25
Grinnz it says you can ask for a tag to be created at codereview.meta.stackexchange.com/

tbrowder tyil: mine is in draft on raku advent wp, should be visible, but more edits coming. 14:52
tyil tbrowder: that's a good sign :>
tbrowder but comments welcome...
tyil tbrowder: currently still at work, so I have no time at this very moment 14:53
tbrowder wp is nasty, but i now write in html. found a cpan module for cli posting, etc.
tyil heh, the tab says "Drafts (1)", but clicking on it says "no posts found"
Doc_Holliwood m: my $s = ''; for ^2 { $s .= sprintf('%s', $_ ) }; say $s;
camelia Your printf-style directives specify 0 arguments, but 2 arguments were supplied

tbrowder that's wp!
Doc_Holliwood why the heck is raku using Str.sprintf here and not the routine sprintf? 14:54
tbrowder maybe i changed visibility...
Doc_Holliwood my $s = ''; for ^2 { $s = $s ~ sprintf('%s', $_ ) }; say $s;
evalable6 01
Doc_Holliwood as admiral ackbar would put it: It's a trap!! 14:55
tbrowder wp draft is still set on "everyone" 14:56
tyil: you are on rakuadvent or perl6advent?
tyil tbrowder: raku 15:00
15:00 RobRaku left
tbrowder my bad. the button i pressed was "everyone" which apparently means see numbers and it shows 3 scheduled, tyil's most likely. 15:00
tyil I have 3 scheduled, yes 15:01
tbrowder i don't know how to make my draft visible
tobs m: my $s = ''; for ^2 { $s ~= sprintf('%s', $_ ) }; say $s;
camelia 01 15:02
tobs Doc_Holliwood: did you mean this ^? Using the method sprintf on $s seems perfectly fine when you use .=
Doc_Holliwood arrgh 15:03
tobs I don't get why "[Your printf-style directives specify] *0* arguments" in the first try though...
Doc_Holliwood i got bitten by a perl5ism
tobs I think there are warnings about it in some cases :) 15:04
m: say "ab"."cd"

's isn't plural.

Avoid plural entirely with a slight reword.
[Coke] fixes his key issue.

sarna hi, what would be the best way of distributing a raku program? we probably aren’t at self-contained yet, are we 15:31
(let’s say I’d like to send a script to my pal and want them to avoid the pain of installing rakudo n friends) 15:32
[Coke] Docker? 15:33
tyil tbrowder: maybe jj has an idea, I'm not familiar with WordPress at all :< 15:34
tbrowder tyil: i think you said you did your advent articles in raw html? or was that someone else? 15:36
tyil I did some raw html in order to get fixed-width text working correctly 15:39
there was no button in the rich text formatter to get this done
tbrowder thnx 15:41
15:43 abraxxa left, abraxxa joined
sarna [Coke]: well, that seems like the only option :( thanks 15:46
did the gsoc project get anywhere? or was it only to reduce the startup time, I don’t remember 15:48
15:51 chloekek joined
tyil sarna: I believe it had limitations on using multiple modules, but was working when you only used core functionality 15:55
sarna tyil: was it self-contained though? I mean it was able to run without rakudo?
tyil I believe it was, yes 15:56
a single binary file that you could share
sarna would be very nice
sometimes at work I have to run a script on a remote server I can’t install anything on 15:57
tyil sarna: I can't check out the project on the GSoC dashboard as I wasn't the mentor of that mentee 15:58
but I can see her name, let me check if searching the 'net uncovers more 15:59
that seems to be the blog that was used to post updates

sarna by the way, does raku automatically close files? 16:09
sena_kun sarna, what do you mean? I mean, what way to work with files do you use? 16:13
jnthn sarna: At exit, I think yes, but there's no promise of them being closed in any kind of timely manner otherwise. 16:15
japhb sarna: File handles that *you* open are not autoclosed, but see the discussions at docs.perl6.org/type/IO::Handle#routine_close and docs.perl6.org/language/phasers#in...will_trait for a way to make sure they close at scope exit. 16:26
sarna: In other words, declaring the file handle as e.g. `my $fh will leave(*.close) = ...` 16:27
AlexDaniel japhb: pretty sure they are closed nowadays 16:30
at exit, even if you use `exit` if I'm not mistaken
or at least that was improved fairly recently (like a year ago or so?) 16:31
16:36 jmerelo joined 16:38 abraxxa left, abraxxa joined
japhb AlexDaniel: I didn't mean at exit, I meant when the FH is out of scope. 16:39
AlexDaniel right! yes
but then, they're still closed once GC-ed, no?
japhb Especially people coming from a refcounted language will commonly make the mistake of assuming out of scope --> closed
AlexDaniel which may happen whenever, but still :)
japhb Yes, but GC can happen after your process is out of handles, because out of handles doesn't trigger GC yet. 16:40
AlexDaniel that's correct, yes :)
japhb wonders if we ought to actually fix that (make an out of handles/descriptors error trigger GC) 16:41
AlexDaniel and I wonder if `will leave` actually works 16:42
AlexDaniel tests
japhb: yeah that doesn't work I think 16:45
not that cleanly for sure
you need to check if the filehandle was created at all, it can be Nil 16:46
then it's fine
will leave { .close with $_ } ?
somehow I just tend to write it by hand: github.com/perl6/whateverable/blob...m6#L31-L34 16:47
less magical I guess
greppable6: will leave 16:48
greppable6 AlexDaniel, 83 lines, 15 modules: gist.github.com/3eaadc506c799f1b3a...e9cc870397
AlexDaniel yep most of these are (relatively) wrong, unfortunately 16:49
jmerelo AlexDaniel: are docs wrong, do you think?
tellable6 2019-11-27T12:01:06Z #raku <tyil> jmerelo currently only my 3 posts are scheduled for the raku advent, do we have any updates from the other people's posts?
jmerelo tell .tyil I'll start nudging everyone. 16:50
AlexDaniel jmerelo: yep, they are
or at least that's what I consider wrong
sena_kun will prepare the posts... hopefully, soon 16:51
[Coke] jmerelo: I think you misplaced a . there.
AlexDaniel there are two examples of will leave on this page: docs.perl6.org/type/IO::Handle
jmerelo [Coke]: sorry
tell tyil I'll start nudging everyone
.tell tyil I'll start nudging everyone
tellable6 jmerelo, I'll pass your message to tyil
jmerelo .tell jmerelo you're dumb
tellable6 jmerelo, I'll pass that message to your doctor
jmerelo .tell tellable6 that's lovely, thanks. 16:52
tellable6 jmerelo, Thanks for the message
AlexDaniel and while both these examples are minimal and maybe don't suffer from the issue, they don't explain that in real code you'll face it
jmerelo AlexDaniel: just the "will leave", right? 16:53
AlexDaniel here's an example:
m: sub foo($foo) { return ‘ok’ if $foo == 42; my $fh will leave { say ‘closing’; .close } = ‘foo’.IO.open; }; foo(42)
camelia closing
No such method 'close' for invocant of type 'Any'. Did you mean 'clone'?
in sub foo at <tmp> line 1
in block <unit> at <tmp> line 1
AlexDaniel I don't remember now, but I think there were other examples when LEAVE would fire unexpectedly 16:54
16:54 abraxxa left
AlexDaniel something about multi dispatch maybe? 16:54
16:55 abraxxa joined
AlexDaniel jmerelo: it needs to be `will leave {.close with $_}` 16:55
ah yes 16:56
these two: docs.perl6.org/language/traps#LEAV...r_and_exit
let's try…
m: sub foo(Int $foo) { my $fh will leave { say ‘closing’; .close } = ‘foo’.IO.open; }; foo ‘oops’ 16:57
camelia 5===SORRY!5=== Error while compiling <tmp>

camelia closing
No such method 'close' for invocant of type 'Any'. Did you mean 'clone'?
in sub foo at <tmp> line 1
in block <unit> at <tmp> line 1
jnthn Alternatively, .?close 16:58
AlexDaniel jnthn: even though it works, it feels so wrong :D
it checks if the method exists and it just happens that there's no .close in Any 16:59
I remember having this conversation with vrurg recently, and he pointed out that there's `andthen` or one of these weirdly named things 17:00
and in my snippet back then it made things easier, yeah
but here I again wish we had .?-like thingy that'd check for Nil 17:01
jnthn .//close :P 17:05

Also 17:48
Can someone with enough privs help reopen this question in StackOverflow? stackoverflow.com/questions/590352...k-wont-end
I know it's a duplicate-ish, but it's bound to still show up in searches and it's much better to point in the answer to the other answer and explain how this case might (or not) be different. 17:49
jnthn jmerelo: It's exactly the same case. 17:54
And the answer applies equally 17:55
So IMO it's probably right to have it marked as a duplicate
jmerelo jnthn: the question is different. And still. Let's asume they've done their homework and didn't understand the answer, or whatever.
jnthn I looked at it and didn't answr it exactly for that reason. 17:56
jmerelo I know, but look at the tiny hand that says "New contributor". Let's try to help. Again, the question is different. They're not understanding what's happening. So let's hold their hand to the correct answer, please. 17:58
jnthn Oddly, they even created a thread pool of size 2 in both questions...
Anyway, I can vote for reopening, but won't because I believe the marking as duplicate is correct. Sorry. 17:59
