Zoffix oh, OK. I'll move it to the COMPLETED.md file 00:17
samcv ok thanks :)
Zoffix: is there a way to see whether we're on 6.d or not yet?
from rakudo code that is 00:18
00:18 damnlie joined
samcv that's this issue? github.com/rakudo/rakudo/issues/1289 00:18
i'll check it out some
Zoffix samcv: yeah, that's the issue. When compiling, you can use the newly available $*W.lang-ver-before('d'), for lexicals, you can just stick them in a file in src/core.d/*, but the rest (such as finding caller's lang version), that's what the Issue is about. 00:20
00:20 raschipi left
samcv Zoffix: so that would wok in rakudo code or no? 00:20
*work 00:21
Zoffix samcv: yeah
samcv i need to control whether .decode is strict or lenient in the decoding same with encoding
ah ok cool
Mark04 forgot quite how long compiling rakudo takes on a raspberry pi :)
Zoffix samcv: that probably is part of the Issue, because you need to know the caller's lang to figure out how to make that method behave
Mark04: took like 25 minutes on mine 00:22
samcv ah yeah

Zoffix Mark04: using these instructions: github.com/MoarVM/MoarVM/issues/34...-395962001 with swap increased to 2GB 00:22

Mark04 Zoffix: hum good tips, I'm already at 2GB swap, but I'm using the arch user repository package for rakudo, and other than changing the architecture to support arm I haven't changed anything so I'll let you know how long it takes :) 00:25
Zoffix ok :)

Kaiepi i'm experimenting with dynamic variables and eval in grammars and i'm a bit confused 01:27
i wrote this hastebin.com/ayutuyagut.pl, but i'm not sure what <?{}> or <!{}> are doing or why they work
01:27 kjk left
Zoffix <?{}> is a successful match if the code inside the curlies returns a true value. <!{}> is the same, except false value 01:28
And in `token type` you probably meant to use just a bare block? So it's executed when that branch matches? 01:29
01:30 TreyHarris joined
Xliff If a subrule in a rule has multiple matches, how do I access each individual match? 01:30
timotimo yes, that's why you have to put an ! when you have = 0 and a ? when you have a = 1
Kaiepi ohhh
Xliff I am trying $/<rule>[], but that doesn't seem to be working.
Kaiepi when would i be able to use <{}>? 01:31
Zoffix Kaiepi: when you're returning something to match 01:32
m: say "foo" ~~ /<{'f+'}>/
camelia ｢f｣
timotimo <{ }> uses the return value of the block and treats it as regex syntax
Zoffix uh
ah
m: say "foo" ~~ /<{'f.+'}>/
camelia ｢foo｣
Kaiepi oh that's perfect for the grammar i'm trying to write for net::telnet
Zoffix Kaiepi: like gist.github.com/zoffixznet/0431129...a9fdbf4f06
Xliff: FWIW, $/<rule> can be written as just $<rule> 01:33
Xliff: what's the .gist of $/ ?
timotimo Xliff: does .gist of the match object help figure out the ... yes
i can also recommend Data::Dump::Tree for dumping match objects
Zoffix I think that module still fails on newer rakudos 01:34
Xliff I am using Data::Dump::Tree
And I am using subrules that are matched via [ <s1> <s2> ]+ % [ ',' \s* ]
Zoffix Xliff: what's the .gist of $/ ? 01:35
Xliff So if I gist, I get alternating lines of s1=..., s2=...
Kaiepi this would be equivalent right? gist.github.com/Kaiepi/420265032e1...4326a6d38a
Xliff Zoffix: One second.
Zoffix m: say "foo" ~~ /<{Empty}>/ 01:36
camelia Nil
timotimo Kaiepi: depends on how the regex engine interprets the return value of a non-taken if or unless
Zoffix Kaiepi: looks like it
Kaiepi what do you mean timotimo?
timotimo m: say "Empty" ~~ /<{Empty}>/
camelia Nil
timotimo m: say "()" ~~ /<{Empty}>/
camelia Nil
timotimo m: say Empty.Str 01:37
camelia
Zoffix m: say "foo meow ber" ~~ m:g/<{<foo bar ber>}>/
camelia (｢foo｣ ｢ber｣)
Xliff Zoffix - pastebin.com/yc10i6uv
timotimo well, it'll interpolate an empty string in that case, it looks like
Zoffix timotimo: I think it's treated as a list of alternatives to match, not just a plain Str
timotimo ah, an empty list, that's better
i forgot we have that feature. it's a good feature. 01:38
i'm going to bed, good luck!
Xliff Zoffix: Any ideas? 01:39
Zoffix Xliff: in $/<rule>[0] 'rule' is what? 'type' in your gist? 01:40
Xliff Yes.
OK. Is there a way to iterate? Does $/<rule>[0] do Iterator?
Because when I do $/<rule>.elems, I get 1
Zoffix I get 2 01:41
timotimo just checking, @<rule> makes no difference?
Zoffix m: say "foo 42, bar 100" ~~ /[$<type>=<[a..z]>+ \s+ $<rule>=\d+]+ % [","\s*]/; say $<type>.elems
camelia ｢foo 42, bar 100｣
type => ｢foo｣
rule => ｢42｣
type => ｢bar｣
rule => ｢100｣
2
Zoffix m: "foo 42, bar 100" ~~ /[$<type>=<[a..z]>+ \s+ $<rule>=\d+]+ % [","\s*]/; say $<type>.elems
camelia 2
Zoffix Xliff: so it *would* be $/<rule>[0], etc.
timotimo Xliff: do you know of GPTrixie? you might be reinventing it 01:42
Xliff timotimo: No, that gives me an error.
Zoffix m: "foo 42, bar 100" ~~ /[$<type>=<[a..z]>+ \s+ $<rule>=\d+]+ % [","\s*]/; for $<type> { say $++ ~ "th type is $_" }
camelia 0th type is foo
1th type is bar
Zoffix eco: GPTrixie
buggable Zoffix, App::GPTrixie 'Generate NativeCall code from C headers file': modules.perl6.org/dist/App::GPTrixi...ail.com%3E
Xliff Ooh! I did NOT know about $++
timotimo is it supposed to put the whole email address in there, too?
Xliff Thanks!
Zoffix timotimo: it's using `author`, but it should be using `auth`, which AFAIK currently is poorly specced. 01:43
But then, nothing stops people from putting email addresses into auth either, I guess
timotimo OK
seeya later 01:44
Zoffix \o
Xliff: it's `$` actually. An anonymous state variables. The `++` is an op.
And since you ain't got a name for the variable you can only access it up there once, so ++$, --$, $++, $-- are the most common operations to do on it 01:45
01:47 Zoffix left

Util lindylex: When I add this code: `say [:$firstHalf, :$reverseSendHalf].perl;` , 02:28
I see: [:firstHalf("bab"), :reverseSendHalf("bab ")].
That space is your problem.
So either the answer *is* false because 'y' is not ' ',
or you need to remove embedded blanks, like `my $without_whitespace = $sring.trans(' ', '')`
lindylex Util: thanks I was trying to figure out what is wrong and how yo see that blank space. 02:29
Util Oops, that should be `.trans(' ' => '')` 02:30
When debugging, use `dd` or `say $something.perl;` , so whitespace is easy to see. 02:31
lindylex Util thanks for that tip.
Util m: my $a = " a b c d e f "; my $b = $a.trans(" " => ""); dd $a, $b; 02:32

Marcool Hi all, I've been struggling with a simple script which is causing perl6 to throw "MoarVM panic: Internal error: Unwound entire stack and missed handler" 08:40
I've reinstalled rakudo, reinstalled both modules that it uses (LibCurl::HTTP and JSON::Fast) and no improvement…
Should I file a bug?
(when I say reinstalled rakudo I mean re-compiled and installed)

hankache hi jj
Anyone interested in translating perl6intro to Russian? 11:25
jmerelo hankache: I know a few Russian users; I don't know how often they hang around here.
.seen shitov
yoleaux I haven't seen shitov around.
jmerelo hankache: maybe create an issue in perl6/marketing? 11:26
hankache jmerelo: I just had someone on GitHub request a Russian translation.
github.com/hankache/perl6intro/issues/184
jmerelo: no need to put it in perl6/marketing since there's already an issue open for it in perl6intro 11:28
jmerelo Besides Andrei Shitov, there's Andrei Melezhik... To reach them, the best might be either issue or contacting them via Twitter (or the Perl 6 facebook group)
hankache: The only thing with perl6/marketing is that quite a bunch of people get notifications. But of course, do whatever you think it's best. 11:29

frankjh Hi I am trying to get a native module of mine installing again. I am 11:40
using 'panda' and I think I have to support 'zef' now.
Currently I can compile the native code, but the perl6 code does not
pick up the shared library object.
jmerelo frankjh: right. Panda is deprecated. 11:41
frankjh: did you setup all paths as indicated?
frankjh jmerelo: Probably not, but I do not find the issue. pastebin.com/raw/zPrx51K9 11:42

Util docs.perl6.org/type/Promise#sub_await says: 13:19
multi sub await(Promise:D --> Promise)
But this code:

camelia Int
Promise
Util indicates that `await` is operating as `await(Promise:D --> whatever_the_result_type_of_the_threaded_op_was)`
, as I would expect (and have relied on in some of my code)

libuv's broken with ipv6, dyncall's broken with nativecall callbacks, gcc's too old iirc 14:03
MasterDuke some sort of BSD, correct? 14:04
Kaiepi yeah, openbsd
MasterDuke doesn't Configure.pl have autodetection of OS and then do some things differently? 14:05
Kaiepi it does, but the issues are in the libraries, not the build script 14:06
MasterDuke Kaiepi: btw, changing topics, it's probably good to get in the habit of using '{*}' (i.e., no spaces) for your protos 14:07
ah
Kaiepi github.com/MoarVM/dyncall/commit/a...716d0b4c5a fixes the issues i was having with dyncall
why {*}?
MasterDuke if you ever want to change the proto to put some actual code in it, you'll need to add a '{*}' 14:08
so it's easier to just use that from the beginning, then you can just put some other braces around it if/when you're adding other code 14:09
Kaiepi you can put code in protos?
MasterDuke yeah

[CaR Grant] Rewrite section on constants

  - Document newly-available auto-coercion
  - Document newly-enforceable type constraints
  - Document ability to use := op and backslashed sigilless names
  - Document anonymous constants
  - Get rid of overly elaborate scoping prose. That belongs to
   the section on scoping.

lindylex I would like to understand why I can not output the value of the class variable pastebin.com/xwiP2Fea 20:04
[Coke] the class isn't constructed at that point. 20:06
at compile time, you're in the middle of constructing the object; are you trying to find that value out when the object is instantiated?
lindylex [Coke] I see. 20:07
I would need to do it in initme
jmerelo [Coke]: When would that code be actually run? Theoretically any code in class scope will be run in compile time?
Zoffix lindylex: you can just stick that linto into `submethod BUILD` to do so: submethod BUILD { say $!halfLength.perl }
That's also a pretty huge way to write a pallindrome checker 20:08
[Coke] jmerelo: I believe it's getting run when the class is being constructed. not sure which phase, but "early".
