parv perhaps a function of dd? 10:14
tyil it seems so, but I'm not using dd in my test
and my test shows it with the \, which of course fails the test 10:15
10:19 mcmillhj joined
jnthn .perl would also do that, I guess 10:19
10:23 mcmillhj left
tyil can I stop it from doing that? 10:23
jnthn Are you actually calling .perl in your test? 10:25
If so, call .perl on the thing you're testing it against?
tyil not yet
but I can add a .perl
jnthn Ah 10:26
Then I'm suspecting it's only showing the \ as part of the error reporting
Rather than it being there in the data
Or at least, it's worth checking if that's what is going on :)
jast I found a moarvm issue the other day on armv7l and I'm going to report the bug the next time I actually manage to get home before night, but just in case I wanted to try and figure it out myself, any smart ideas on what docs I could read to get an overview of the 6model under-the-hood stuff without going through all of the code? 10:28
jnthn jast: What kind of issue was it?
jast a SIGBUS due to alignment issues
possibly a compiler problem, too, I haven't tried too many yet 10:29
just one so far. lack of time and all that...
jnthn Ah. I can probably give more hints with a stacktrace 10:30
Does it get so far as building Rakudo, or does it explode well before that?
jast the build all succeeds 10:31
anyway, I've already traced it, it fails in P6num's set_num
the default case of the switch block, as I recall, but I'd better check again
for getting more info on where the data is actually coming from I'll probably need to collect more than just the stacktrace 10:32
jnthn Do you observe the failure in a nativecall test?
jast doesn't help that I'm not exactly literate in ARM-style instruction sets
no, it's when I launch perl6.moarvm 10:33
jnthn Ah
Then maybe take a look in P6opaque.c which does the layout of objects
It may be doing insufficient alignment ahead of a P6num
But iirc that's a data-driven process, based on alignment configuration which may be in P6num.c 10:34
jast well, the SIGBUS happens in a 'bx' instruction, that would be code-driven, right?
jnthn I meant that the calculation of object layout and alignment may be 10:35
jast ah looky here, I kept a copy of the output... gist.github.com/jast/df9ba1a023222...7ad1dfce45
in another run I checked the register contents and lr was, indeed, not aligned
but I know nothing about the registers and all that, so that didn't tell me a lot :)
I suppose this is an opportunity to start learning more about ARM 10:37
jnthn p &(((MVMP6numBody *)data)->value) may be interesting 10:38
(To see what the lower bits of the address are, which may hint an the alignment issue)
10:39 Cabanossi left 10:41 Cabanossi joined
jast $2 = (union {...} *) 0xb413266a 10:42
so I guess it wants 64 bit values aligned at 64 bits, which this isn't 10:45

ZzZombo #perl6, I'm still struggling to make attribute binding to work, what I need is to make an attribute bound to value in the setter. Can somebody show a quick example? 12:05
12:07 eliasr joined
timotimo maybe you need to set the incoming parameter "is raw" so that it doesn't recontainerize what you're passing into a read-only container? 12:08
what is your setup? are you using a proxy?
ZzZombo yes, it is result of `Str.substr-rw` 12:09
timotimo ok, try an "is raw" on the argument to the STORE block in the proxy
ZzZombo m: class C { has Str $.s;multi method s is raw{return-rw $!s};multi method s(Str:D \s) is raw{$!s:=s};submethod TWEAK(:$s){ self.s($s)} };my $a=C.new(:s<a>);my $s='aaaaaaaaaa';$a.s($s.substr-rw(2,3));$a.s('asd');say ($a,$s) 12:11
camelia 5===SORRY!5===
Trait 'is raw' needs whitespace before block
at <tmp>:1
------> 3$.s;multi method s is raw{return-rw $!s}7⏏5;multi method s(Str:D \s) is raw{$!s:=s}
Missing block (apparently claimed by 'is raw')

------>…
ZzZombo m: class C { has Str $.s;multi method s is raw {return-rw $!s};multi method s(Str:D \s) is raw {$!s:=s};submethod TWEAK(:$s){ self.s($s)} };my $a=C.new(:s<a>);my $s='aaaaaaaaaa';$a.s($s.substr-rw(2,3));$a.s('asd');say ($a,$s)
camelia (C.new(s => "asd") aaaaaaaaaa)
timotimo ah, you're already using a sigilless parameter, that's equivalent to "is raw" 12:12
oh, it looks like it worked what you wanted there? 12:13
like, what's your goal here?
ZzZombo no? the original string didn't change. I want to be able to change the provided part of a string from my objects.
timotimo then what you want is assignment, not binding 12:14
you're binding "asd" into $!s, at which point the result from substr-rw is replaced with "asd" 12:15
you need two different methods here, one to bind so you can get the substr-rw result in, and one to assign so you can assign into the substr-rw result

lucs How do I get Inline::Perl5 to use my just installed more recent version of Perl 5? 14:15
(the more recent version is the one found in the path where I am using Inline, but it sees my previously installed perl5) 14:17
14:20 comborico1611 joined
lucs (uninstalling and reinstalling Inline changed nothing) 14:20
timotimo lucs: i'd say inline::perl5 compiling a helper .so during its installation could have something to do with which perl5 actually gets used 14:26
lucs Makes sense, trying to delete relevant stuff (but not sure exactly what) to reattempt build. 14:28
timotimo i'd zef install --force Inline::Perl5, that ought to do it 14:29
ilmari lucs: presumably it builds against whichever perl is first in your path
lucs timotimo: Tried that, no luck.
Oops, meeting 14:30
TTYL
ilmari 'zef uninstall Inline::Perl5' first?
lucs ilmari: Yep, did that
El_Che rm -rf ~/.perl6 should fix it, but you'll loose other home installed modules 14:32

Zoffix Along with `samewith` weirdness, there's also this thing, where you have to pass `self` to nextwith/callwith: 14:44
m: $*OUT.WHAT.^lookup('print').wrap: my method (|) { nextwith 42 }; say 42
camelia Type check failed in binding to parameter '<anon>'; expected IO::Handle but got Int (42)
in method <anon> at <tmp> line 1
in block <unit> at <tmp> line 1
Zoffix Despite `nextsame` knowing what to do... Was this really the design of how this thing was meant to work?
Feels like the wrapper is in want of having its dispatcher tweaked or something 14:45
ugexe zef nuke StoreDir, or zef look Inline::Perl5 && make clean && zef install . 14:46
Zoffix tyil: didn't see anyone mention: the backslashes in `"test\@domain.org"` come from `.perl`. It escapes the `@` because depending on what follows, it could be interpreted as an interpolated Array. Even though in this particular case it wouldn't by escaping all the `@` it doesn't need to know what follows it. 14:47
tyil I saw it before in Config::TOML too, and back then I believed it to be a bug in their lib, but couldnt figure out why 14:48
lucs Hiya DrForr :)
tyil jnthn: also said it was probably the .perl part 14:49
which seems to also be used in Config::TOML, so now I can try to fix another issue as well
and the test I had my problem with earlier today now works as well :>
so everything is fine again
lucs Okay, getting rid of ~/.perl6
tyil if I can fix the Config::TOML bug I can resolve another small bug in cpan6, and then continue on writing more tests 14:50
but that'll have to wait until I get home

El_Che ugexe: it looks like zef could use a clean-install command :) 16:11
ugexe perhaps, or alternatively makefiles could run a make clean step first since they will be more familiar with their build system 16:13
im open to suggestions though
perlpilot zef caches module downloads? 16:14
ugexe yes
perlpilot Hmm. if this were only cpan, I'd say only cache the tarballs and unpack them each time. 16:15
16:15 committable6 left 16:16 committable6 joined, ChanServ sets mode: +v committable6
El_Che why the caching actually? 16:16
ugexe yeah managing a transparent handling of directory based repo vs archive based repo is not fun
El_Che I can imagine
perlpilot ugexe: you could make tarballs out of the repos :) 16:17
ugexe a couple of reasons. one is because a name/auth/ver/api combo is meant to represent that dist no matter what so caching, in theory, should be perfectly fine
another was so there was a work directory to see what actually happened in a build 16:18
16:18 cdg joined
ugexe and finally because it is faster (maybe not compared to tarballs, but to git cloning yeah) 16:19
well, it should be faster than tarballs but I mean its probably not fast enough to make much difference
pmurias what is more correct 'Return 1 if ..., 0 otherwise' or 'Return 1 if ..., otherwise 0' 16:26
moritz return ... ?? 1 !! 0 16:28
perlpilot I don't know about "correct", but I like the second one
moritz oh, this is about language, not code
sorry
perlpilot moritz: yeah, it's hard to tell these days sometimes :)
ilmari prefers the second form too 16:29
ugexe perlpilot: then i have to do cross-os adapters for creating tar archives, not just reading them
perlpilot yeah, that would suck. 16:30
Better would be to give a --no-cache option or something 16:31
--refetch? 16:32
ugexe you can disable the cache with --/cache
--refetch would not help because the distribution is still the same 16:33
er --/cached 16:34
but this also means it can be disabled in config.json 16:35
16:38 Cabanossi left
El_Che ugexe: I am curious where did you get the --/ syntax 16:39
little weird
ugexe its built in to perl6
El_Che ok, now I am curious where perl6 got it :)
16:41 Cabanossi joined 16:42 jferrero joined
moritz you could ask [particle]1 16:43
ugexe not sure, but whats the alternative? if you prefix with `no-` or some such then your MAIN signature no longer works like most other subs because you cant have a `no-whatever` param in the signature 16:44
16:45 wamba left
moritz ugexe: no, the preprocessor could do that for you 16:45
ugexe and if you have two flags (true and false) that means you could also set them both which would conflict
moritz that's the same with --/foo and --no-foo 16:46
El_Che before lizmat fixed MAIN params where pretty useless
ag options before commands stuff.
ugexe --no-foo is a different name, it would (should) show up twice
moritz there's a step that translates @*ARGS into a capture. It could turn --no-foo into :foo(False)
ugexe --foo and --/foo would not
well yeah, but now your MAIN signature handles named items significantly different than other subs 16:47
El_Che I have no associaciation in my head with / as a negation
moritz ugexe: it's not MAIN that does it
El_Che hence the question
ugexe when i program a MAIN sub i'm not thinking about the preprocessor, and hence not thinking if I can add a :no-whatever option or not 16:49
if I already have a :whatever, then I cannot add a :no-whatever
moritz but, how often do you want to add both a :whatever and a :no-whatever option? 16:50
this sounds like a very theoretical option to me
s/option/problem/
perlpilot You have: no tea.
moritz Getopt::Long in Perl 5 does it
argparse in python does it too (but without the dash) 16:51
ugexe and yet people love perl6's MAIN handling and i never hear praise about either of those
ilmari ugexe: if you have a Bool :whatever you can do --/whatever to disable it 16:52
moritz ugexe: but it's not because of the weird negation thing that people love Perl 6's MAIN handling
El_Che should you just give default values (false) and add 1 bool to disabled if needed? 16:53

ugexe ilmari: right
El_Che so you'll end up with no --cache option, but a --no-cache is cache is the default
ugexe and what if the user chooses the defaults? 16:54
El_Che if cache is the defaut
ugexe: he'll use a wrapper?
ugexe in zef you can set any of the plugins to any command you want
flag rather
moritz well, i'd proppose --cache calls MAIN(:cache), and --no-cache calls MAIN(:!cache)
and MAIN can do a $cache // $users-default 16:55
and MAIN would be declared as sub MAIN(Bool :$cache) { }

perlawhirl Hi perlers
python's itertools.permutations takes a second argument that can give you permutations of length N 19:34
ie. list(permutations('ABC', 2)) --> [(A B) (A C) (B A) (B C) (C A) (C B)]
trying to find a nice way to do it in perl and this is what i got
my @x = <A B C>; my $n = 2; say ([X] ^@x xx $n).map({ @x[|$_] if set($_) == $n })
m: my @x = <A B C>; my $n = 2; say ([X] ^@x xx $n).map({ @x[|$_] if set($_) == $n })
camelia ((A B) (A C) (B A) (B C) (C A) (C B))
moritz m: say permutations([<a b c>], 2) 19:35
camelia Too many positionals passed; expected 1 argument but got 2
in block <unit> at <tmp> line 1
moritz m: say combinations([<a b c>], 2)
camelia ((0 1) (0 2) (1 2))
moritz m: say combinations([<a b c>], 2).map: *.permutations
camelia (((0 1) (1 0)) ((0 2) (2 0)) ((1 2) (2 1)))
moritz m: say combinations([<a b c>], 2).map(*.permutations).flat
camelia (0 1 1 0 0 2 2 0 1 2 2 1)
moritz too flat :-) 19:36
perlawhirl moritz: the combinations trick works... albeit in a different order 19:38
