i moved the offending test to the top of the only test file 00:03
Zoffix is getting ---INIT___ a bunch of times; then "This type (Submethod) does not support positional operations" 00:04
HoboWithAShotgun: what rakudo version are you on? 00:05
HoboWithAShotgun This is Rakudo version 2017.08-91-g9785356 built on MoarVM version 2017.08.1-128-gde6dced 00:06
homebrewn
Zoffix Yeah, runs on 2017.08 00:07
Looks like some bug was introed afterwards :o
00:07 ryn1x joined
Zoffix Between 2017.08 and 2017.09 00:07
HoboWithAShotgun i seem to have a talent to find these :-D 00:08
Zoffix .tell AlexDaniel if bisections and regressions are your thing, seems something got broken between 2017.08 and 2017.09. If you run the t/01-* test, in 2017.08 it shows some output, but on 2017.09 it crashes with " 00:09
yoleaux Zoffix: I'll pass your message to AlexDaniel.
Zoffix grr

Zoffix AlexDaniel "This type (Submethod) does not support positional operations": github.com/zoffixznet/perl6-Unit-SI
AlexDaniel let's see…
Zoffix Line points to definition of this sub: sub postfix:<V> ($value) returns Unit::SI is export {
return $value does( Unit::SI[ %UNITS<volt><signature> ] ); 00:10
};
HoboWithAShotgun: "but even if that is wrong, it doesnt explain why i see the same value for $a and $b" but you're calling callwith with same args (and could use `callsame`) aren't you? 00:14
Why is it expected for them to change?
00:15 rindolf left
HoboWithAShotgun yes, but at least for the first invocation. i mean $a is supposed to be the LHS and $b to be the RHS of the infix 00:15
Zoffix oh 00:17
If I do `my $a = 12V; my $b = 12A; say "== $a, $b";` in test file I get both as 12A 12A
00:18 kyan joined
Zoffix And there's no volt method in Units::SI 00:19
AlexDaniel: looks like the regression likely just changed the error. ^ the "volt" thing is in the same method that errors out on more recent rakudos
oh wait... maybe it don't gotta have methods 00:20
AlexDaniel how long does it take to run that test file…
Zoffix right, never mind
AlexDaniel doesn't make it in 10 seconds here :) 00:21
Zoffix AlexDaniel: ages. 11.8s to precomp; 0.6 afterwards

HoboWithAShotgun that explains why we see the 12A 12A
it's 12V == 12A,

committable6 Zoffix, ¦HEAD(322dcc9): «["Foo+\{Meow}", "Foo+\{Moo}"]»
Zoffix HoboWithAShotgun: not really
HoboWithAShotgun: oh, now I do. Yeah, you're mixing right into the cached constant
HoboWithAShotgun: you need `Int.new($value)` up in there; thought it only recently got fixed to Do The Right Thing 00:27
AlexDaniel well, the big picture is here: gist.github.com/Whateverable/1fa08...2fbc5d4f04
Zoffix recently as in... a few commits before 2017.10 release
HoboWithAShotgun you mean it should work like this, it just doesn't because my perl is outdated 00:29
Zoffix HoboWithAShotgun: not how you have it, but if you add Int.new($value) to get a new object instead of the cached constant, then yeah, then it'll work and yeah, that works correctly only on 2017.10 release 00:30
HoboWithAShotgun: also, it only affects values under 100, so you could test with 120V == 120A
00:31 aborazmeh joined, aborazmeh left, aborazmeh joined
Zoffix HoboWithAShotgun: also, you could do `use nqp; nqp::div_I(nqp::decont($value), 1, $value.WHAT)` instead of Int.new releases, but note that very soon that nqp op hack will stop working (so you'd need to use Int.new instead) 00:32
HoboWithAShotgun will not enter where will be dragons until i am confident in slaughtering griffins, tyvm 00:34
uh, mixed persons, that means bad luck 00:35
Zoffix m: use nqp; constant can-Int-new = ?try 'nqp::boxI_I(1, 1, Int)'.EVAL; sub rebox-Int {can-Int-new ?? Int.new($^v) !! nqp::div_I(nqp::decont($v), 1, $v.WHAT) }; my $x := rebox-Int 2; $x does role Meow {}; my $y := rebox-Int 2; $y does role Moo {}; dd [$x.^name, $y.^name]

committable6 Zoffix, ¦2017.08: «["Int+\{Meow}", "Int+\{Moo}"]»
HoboWithAShotgun also, no point when it's deprecated anyway
Zoffix HoboWithAShotgun: what is?
HoboWithAShotgun the nqp hack you mentioned 00:36
Zoffix You could use ^ that. But it's a hack and we don't support users' use of nqp
HoboWithAShotgun (where will be dragons) == nqp
Zoffix HoboWithAShotgun: it won't be deprecated. just optimized and optimization will remove the side effect that it reboxes it
I mean, use Int.new, sure, just keep in mind users with older compilers won't get the stuff working right 00:37
Anyway, the OP issue... 00:38
m: multi sub infix:<==> (Int, Int) is default {say "here"; nextsame }; say 42 == 42
camelia here
here
True
Zoffix m: multi sub infix:<ZZ> (Int, Int) is default {say "here"; nextsame }; say 42 ZZ 42
camelia here

Zoffix Looks like something to do with `==` op
Gonna take a look at it after fixing callyalater's issue :) But again, the fix (if it's broken and needs fixing) won't be on 2017.08 compiler :)
Yeah, looks like a proper bug; using `UInt` types instead of `Int`s + is default doesn't run it twice 00:39
m: multi sub infix:<ZZ> (Int, Int) is default {say "here"; nextsame }; say 42 ZZ 42 00:40

HoboWithAShotgun zoffix: the haters would deem themselves proofed correct, the hopeful will have sympathy and the rest won't probably give a flying clusterfibonacci 00:43
i was told to avoid the f word and fibonacci was the only other one i could think of :) 00:44
zoffix: btw, there is a similar issue in the Str method 00:46
it also gets called twice *sometimes*, i worked around that
may be the same cause
AlexDaniel Zoffix: well I'd say that there's something wrong about that commit, but that's a huge diff of nqp stuff so no idea. A revert is not supposed to introduce completely new behavior, but this one was done manually so ¯\_(ツ)_/¯ 00:49
Zoffix AlexDaniel: OK thanks. I'll leave the buggy code open on one of the desktops. Maybe will remember to try to golf it later 00:50

Todd_ How do I get Perl6 to check for pm6 first? Is there a way to tell "use" to use the extension? 01:08
HoboWithAShotgun ok, I can't use Int.new in my postfix or else i must provide a multi for Rats et al, so i figured 01:09
m: my $x = 2; say $x.WHAT.new( $x + 3 );
camelia 5
HoboWithAShotgun but then
my $x = 0.3; say $x.WHAT.new( $x + 0.2 );

Add example "Add actions directly", review needed

Since this tutorial shows actions in grammar only by associating a action object, I add an example to introduce write actions directly.
As a nonnative, maybe there is some improper expression in the text.
Thank for your review!
Zoffix Todd_: it's something along the lines of using Terminal::Print or termios to set terminal to non-buffering mode and then you can just use getc or something

geekosaur yes because it's looking for a combining character. there's something or other to change that low level behavior that I don;t recall of the top of my head 03:29
but since perl 6 works by default at the grapheme level, it does that by default
Zoffix You could try switching $*IN to binary mode ($*IN.encoding: Nil) and using .read(1)
instead of .getc
03:30 cpage_ left 03:34 noganex joined
Todd_ I am not following. how would I write `my $c = $*IN.getc;` in encoding? 03:37
03:37 noganex_ left
geekosaur I ... don;t even understand the question 03:39
Zoffix Todd_: are you trying to read the key or read one character?
03:39 Cabanossi left
geekosaur perl; 6 is already doing encoding, that is why it is waiting for more. Unicode graphemes can consist of multiple characters 03:39
Todd_ I am trying to read one charatcter at a time. Flush first, so I only get new stuff 03:40
Zoffix Todd_: it'd often need to read more than one character; otherwise it doesn't know when you've finished entering your character.

Todd_ I am looking for one instance of any key on the entire keyboard being pressed. Weird keys too. 03:41
Zoffix Todd_: ^ that's a 2000-byte single character
geekosaur Todd_, good luck with that.
(a) shift doesn;t send a character 03:42
(b) F1 sends, depending on the exact terminal, up to 5 or so
03:42 wander left
Todd_ well, how do I read everything else, except shift. I will compromise on that 03:42
Zoffix Why "good luck"? There are many programs that read presses like Ctrl and Shift 03:43
Like most video games
geekosaur by not using a terminal, yes
if you are using a GUI you can get raw key events
if you are using a video game console you get raw key codes
03:43 mson left
geekosaur temrinals are neither 03:43
zostay does zef precompile during installation? 03:44
Zoffix zostay: yes
zostay hmmm
Todd_ this is how I do it in Perl 5. vpaste.net/reOF7
Zoffix Presumably you can set the same modes with termios module or whatever 03:46
Todd_ xterm, terminal, ssh, xrdp
geekosaur try pressing F1
Todd_ I want it all.
geekosaur that does not handle it
heh. F1 doesn;t even go to the terminal on my system, it pops up help. 03:47
03:47 Zoffix left
Todd_ chuckle. It asks me if I was to read teh Xfce manual. I will compromise 03:47
geekosaur lpaste.net/359585 03:51
to get any rawer than that, you'd have to use X11 operations and process key events; I don't know if anyone has xcb bindings for perl 6 yet
Todd_ in the example for termios, the furst key I press gets ignored. The second one gets read.
03:54 wander joined
Todd_ maybe I typod something. I will copy and paste. 03:55
No such method 'ord' for invocant of type 'Buf[uint8]' But a lest it read the first key
geekosaur hm. that error is probably correct, if you go to fully raw mode you are not working with Str any more 03:56
ptogrammers always think a string is a string. They're always wrong but most languages let them get away with it and silently do the wrong thing in many cases 03:57
(or verbosely, for e.g. early python 3 releases)
wander m: my @primes = ^100000 .hyper.grep: *.is-prime; say @primes; 03:58
camelia (signal XCPU)
wander m: my @primes = ^100000 .hyper.grep: *.is-prime; say @primes.head(10);
camelia (signal XCPU)
Todd_ and it really messed up my terminal, leaving it in raw mode. 03:59
geekosaur hm, it should have reset it. I didn't change that part
oh, wait. because of the error. 04:00
type: stty sane
then control-J
(NOT enter!)
Todd_ that fixed it 04:01
:-)
geekosaur testing this time before sending update... 04:05
lpaste.net/359585#a359587 04:07
more correct would be to extract the byte from the Buf, but this will do 04:08
Todd_ And it works! Thank you!

geekosaur no, it's not 100% the same, ~~ does more stuff than just rearranging
it thunkifies, it sets $_ locally, it does a number of other metasyntactic things 05:02
wander ok
I rewrite it in "b11d" ~~ /:r b .* d /, it shows the match fails.
have nothing to do with token, grammar,... 05:03
geekosaur no, it has to do with :ratchet 05:04
wander right
thank you, I see that
that's what I concentrate on, whether I write a wrong regex/token 05:05
05:06 cdg left
geekosaur smells like :ratchet is iperating at the wrong level. it's preventing the .* from backtracking instead of preventing backtracking from re-entering the regex (which is kinda irrelevant here, I think). or if :r has that effect when standalone then this might be a gotcha 05:06
because .* will, if ratcheted, commit to consuming the rest of the string and not backtrack to allow the d to be literally matched
wander yes 05:07
geekosaur and it looks like this is expected, so perhaps use of .* in a regex with :r should be in the Traps documment 05:08
*document
regex really expects to be used with things like keywords that don't require backtracking to work 05:09
Todd_ I forgot how to trim a \n off the end of a sting. Trim seems to only get the white space. 05:20
geekosaur works here? 05:22
pyanfar Z$ 6 'my $x = "foo\n"; dd $x.trim' 05:23
"foo"
note that if you got a literal \n into it, it wont be whitespace and won't be removed 05:24
pyanfar Z$ 6 'my $x = q{foo\n}; dd $x.trim'
"foo\\n"
Todd_ $HostName ~~ s/\n//; worked. I do not understand pyanfar
geekosaur that is my prompt
and 6 is an alias for running perl 6 one-liners

stmuk_ piojo_: I think distro packages probably should be starting with packing rakudo itself rather then star. Star would be a meta package of rakudo itself and modules. Rakudo is supposed to have DESTDIR support although last time I looked I was unclear whether it was complete 08:06
piojo_: In fact rakudo itself is probably 3 packages -- nqp, MoarVM and rakudo proper 08:08
piojo_: its probably worth checking what Debian and OpenSUSE have done already
08:08 dominix joined
dominix hi all 08:09
I have a tricky things. How do I declare my first elemnet of an array to be empty when using <> 08:10
for ex : my @aa = < empty foo bar> 08:11
if I say : my @aa = < "" foo bar>; it doesn't works
it may be trivial, but I don't find. 08:12
08:17 piojo joined, piojo_ left
piojo dominix: What do you mean by an empty value? An empty list? An empty string? the "Any" type value? 08:32
either way, the short answer is that you can't do it with <>, because only literal strings are allowed 08:33
You can add an empty string with <<>> (or "«»"), but even with that, it's not a true empty string, but an IntStr 08:34
m: say «'' 'second element' third fourth».perl
camelia (IntStr.new(0, ""), "second element", "third", "fourth")
piojo The first element can be interpreted as an empty string, or as 0.
08:37 evalable6 left
piojo stmuk_: I'll add a note to the rakudo-star (3rd party) package suggesting people install rakudo instead. 08:37
08:37 evalable6 joined, ChanServ sets mode: +v evalable6
piojo stmuk_: this is a psychological problem, more than anything else. When I first installed perl6, I found there was no perl6 software/package, so I searched for what it was called. All the blogs talk about installing "rakudo star", so that's what I searched for. (To find that it didn't work.) I didn't know what "rakudo" was, but I thoughtit would be less appropriate, since it's not the recommended software... 08:38
it's only a minus for user acquisition--it makes very little difference to a current user. 08:39
stmuk_ to be frank the packaging of perl 5 in distributions historically has usually led to upstream advice to avoid it 08:49
probably because CentOS etc. ship years old versions .. probably less of a problem with arch :) 08:50
although anyone installing the current debian stable rakudo (2016.12) will probably find many modules no longer work 08:52
eg. DBIish 08:53

chakli oh, didnt know 10:19
AlexDaniel chakli: so WhateverCode like * + * will do, or you can try { $^a + $^b }

geekosaur piojo, there's still at least two reasons to avoid the distro package: 11:42
(1) you dont control when things get upgraded, upstream does. bad if you are developing and the API changes when you do a system update 11:43
(2) the system may be using that package and its dependents, and replacing versions with newer ones may break the system
11:44 piojo joined
geekosaur (someone tried that with perl on debian. dpkg utilities depend on perl, or did at the time. dpkg broke *badly* and they ended up reinstalling) 11:44

piojo, there's still at least two reasons to avoid the distro package: 11:45
(1) you dont control when things get upgraded, upstream does. bad if you are developing and the API changes when you do a system update
(2) the system may be using that package and its dependents, and replacing versions with newer ones may break the system
so it's still a good idea to avoid distro packages if you are developing stuff
stmuk_ geekosaur: while agreeing with most of what you say .. I'd say there are practical reasons for using distro packages in large organizations 11:49
so it depends on what sort of development is happening
geekosaur to a point, yes. I;ve been there. and quite a few largs orgs actually maintain their own packages specifically so they have control over the issues I mentioned
(like the one I used to work for) 11:50
most of them also have isolation so devs are in an environment where they see the dev-intended version instead of the system one
stmuk_ there are developers who probably should use vendor supplied languages in some situations (although I doubt anyone on this channel should) 11:51
geekosaur (heck, if the org is big enough, it actually rolls its own *distribution*)
(usually based on some vendor distro but updated on the org's schedule, with org-required variations, and fully regression tested and supported by the org with upstream vendor only brought in when necessary / problem is replicated on unmodified vendor distro) 11:52
stmuk_ all that works fine until the one person who set it all up leaves :) 11:55

lizmat what symbol was missing? Was that during install or during running? 16:25
knight__ running &CSV
maybe some "low level" lib... 16:26
but, I have installed libtext-csv-perl (to debian)
lizmat Text::CSV doesn't use any low level lib, it's Perl 6 code only
not even any nqp ops in it 16:27

18:14 ryn1x left
wander of course I can rewrite and put all actions suffix, but it seems action objects' method is always called after regex got matched 18:17
curious whether actions within grammar are more flexible
18:18 mson left
moritz they aren't 18:24
18:26 darutoko left
moritz in a compiler, for example, it would be reasonable to have some things inline in {} blocks that deal with symbol tables for example, and need to happen immediately 18:26
but to still have regular action methods that transform the parse tree into an AST
wander agree, it happens that i translate text on the fly 18:31
back to the origin question, do action objects' methods always perform after the regex got matched? 18:33
moritz yes

ugexe zef uninstall zef && git clone github.com/ugexe/zef && cd zef && perl6 -Ilib bin/zef install .
0.1.31

ugexe then do `zef install PDF --deps-only`, then record the full output of `zef install PDF --debug` (so if it does not work I can take another guess) 19:36

Brumbazz Hi :> I've just seen the following perl6 code on stackoverflow: someList.pairs.max(*.value).key <- how does that *.value work ? What's it called ? Thanks in advance :> 21:15
HoboWithAShotgun it's called Whatever/Whatevercode and it's a pit of snakes bridged by narrow planks 21:16
21:16 lowin left
HoboWithAShotgun basically the * introduces a closure and represents the argument to said closure, but only until accessed then it means the second argument and so on 21:17
so grep({ * ~~ Int }) and grep( * ~~ Int) is equivalent code 21:18
so grep({ $_ ~~ Int }) and grep( * ~~ Int) is equivalent code 21:19
Brumbazz Aha, so is value just the value of the pair ?
