lambd0x The newest rakudo is more reliable for large sized inputs when it boils down to sorting algs (e.g., bubble up to counting, bucket) ;) . I enjoyed seeing it had improved performance in comparison to last month. Gotta sleep, later. 00:46
00:47 tushar joined 00:48 Girafferson joined 00:50 pierre_ joined
tushar I have an array and I would like to create same length of array by joining the index of first array with a text. I am achieving this by below code. Is there any other way of doing the same? 00:53
m: my @a = [1..4]; for @a.pairs.hash.keys.sort -> $idx { say join("", "V", $idx); }

camelia rakudo-moar 8be36b: OUTPUT«[0V 1V 2V 3V]␤»
tushar geekosaur: you are doing joining of array element with text, not array index with text. Also, joining results are other way around. I am trying to get "V0, V1, V2, V3". 01:08
geekosaur m: my @a = ^4; say @a.keys >>R~>> 'V' 01:09
camelia rakudo-moar 8be36b: OUTPUT«(V0 V1 V2 V3)␤»
geekosaur m: my @a = [5..8]; say @a.keys >>R~>> 'V' 01:10
camelia rakudo-moar 8be36b: OUTPUT«(V0 V1 V2 V3)␤»
01:11 perlawhirl joined
tushar geekosaur: thanks. How can i forget R operator? hmm.. 01:11
perlawhirl alternatively...
m: my @a = 1..4; say @a.keys.map('V'~*) 01:12
camelia rakudo-moar 8be36b: OUTPUT«(V0 V1 V2 V3)␤»
tushar Is there anyway to check the empty array?
geekosaur or alternately
m: my @a = ^4; say 'V' <<~<< @a.keys
camelia rakudo-moar 8be36b: OUTPUT«(V0 V1 V2 V3)␤»
geekosaur and what is "check the empty array"?
m: my @a; say +@a 01:13
camelia rakudo-moar 8be36b: OUTPUT«0␤»
tushar In perl 5 we can check whether an array is defined or not using "define" keyword. I read some where that defined doen't work exactly same as Perl5. So, is there any way to check if array is empty array or not? 01:14
geekosaur I thought they removed that, actually; defined is not sensible on list or hash 01:15
(iirc it did'nt tell you whether it was empty; it told you whether it had storage allocated) 01:16
01:17 pierre_ left
tushar hmm.. How can we do that in Perl 6? 01:18
Juerd tushar: Just use the array itself as the condition 01:19
geekosaur as I already showed
Juerd m: my @array = (); if (@array) { say "Not empty" } else { say "Empty" } 01:20
camelia rakudo-moar 8be36b: OUTPUT«Empty␤»
Juerd m: my @array = (1, 2, 3); if (@array) { say "Not empty" } else { say "Empty" }
camelia rakudo-moar 8be36b: OUTPUT«Not empty␤»
geekosaur (and yes, at least as of perl 5.18 defined @array and defined %hash are deprecated)
Juerd Note that this is the same in Perl 5 and Perl 6. Even in Perl 5, you shouldn't use defined with arrays, as geekosaur already explained.
tushar @geekpsaur and @ Juerd.. thanks for your help 01:21
perlawhirl tushar: also, the brackets aren't required around simple conditionals like this... more idiomatic perl6 is just: if @array { ... } 01:23
unless you're trying to write polyglot code that runs in both perl 5 and 6 :D 01:24
tushar perlawhirl: thanks. I am getting used to it now.
geekosaur in p5: my @a = 1; pop @a; # @a is now empty but defined
which usually isn't what you intended, and arguably allocation state is an internal detail that was being leaked 01:25

also, not the first time this is brought up -- there's probably an RT somewhere :) 08:22

El_Che aah. I hate it when DHL marks something as 'delivered' when it isn't 08:34
lizmat El_Che: don't get us started on DHL :-) 08:35

delivery seems like something that's tricky to get right
El_Che lizmat: the USA import hing?
t
lizmat El_Che: yeah that
08:35 zakharyas1 joined
lizmat still waiting for them to take us to court :-) 08:36
brrt wonders about that story
lizmat in short: you cannot send something from NL to yourself in the US if you're not a US citizen 08:39
arnsholt tadzik: Logistics is tricky. Chock full of NP-complete problems
lizmat DHL gladly did and charged us for it there and back. we still refuse to pay
arnsholt Travelling salesman for example is a pretty fundamental part of logistics
tadzik nodnod
moritz arnsholt: the algorithmic side usually isn't the problem 08:40
arnsholt: the problem is more regulations, company policy and stuff
arnsholt That's true. There are good approximations for TSP
moritz dealing with organizational boundaries
all that "good" stuff
El_Che dhl is annoying. When you order stuff from the USA to BE, they automatically add import taxes + an administrative fee for their work 08:41
other don't do it
you only pay if customs thinks you should pay (base on value or volume or whatever)
dhl does it for you without asking 08:42
brrr
08:43 andrzejku left 08:45 bjz left, RabidGravy joined
masak lizmat: curious. so the shipment actually got all the way to the US, and then got sent back? 08:46
lizmat: one would think that DHL had been in exactly such a situation before, and could be a little proactive -- "hey, this won't work" or something 08:47
lizmat yup, all the way to Cleveland, OH (destined for Salt Lake City) and then back
masak: exactly our point
08:47 donaldh joined 08:48 bjz joined, bjz left
masak lizmat: I don't see how it's in your interest to pay. I don't see how it's in their interest to take you to court over such an absurd thing. (though I Am Not A Lawyer.) 08:49
08:49 bjz joined
lizmat well, they've been threatening to do this for over a year now :) 08:49
llfourn_ it's probably in their interest to at least threaten it ;)
lizmat well, that's the thing, they don't threaten themselves 08:50
they have a collection agency do that
masak outsource your threatening
llfourn_ ah
tadzik "we're not evil"
lizmat and now I think the collection agency basically has told them this isn't working
and now they don't know what to do
tadzik: I don't think they're evil, just incompetent 08:51
after the collection agency returned the contract to get the money from us to DHL
they said they would reply
to this day, we never got a reply in writing from DHL
just a phone call from some understudy at DHL who was told to phone us to tell us they decided we should pay 08:52

they cut you with the razor

psch i think that's on composition order, somehow 09:36
m: class A { has $x handles <foo> }; say A.^can('foo');
camelia rakudo-moar 8be36b: OUTPUT«(foo)␤»
psch a handled method gets added to the class of the Attribute
but the role-stub check probably happens before that
no idea if we can change that
jnthn It's because role composition happens before attribute composition because roles might bring along attributes
llfourn_ hmm that makes sense 09:37
jnthn That in itself can't change. It's possible that the handles trait could do its work more immediately but I fear that'd have a different surprise
llfourn_ I'll make an RT for later consideration :) 09:38
psch ISTR we have that already
jnthn oh...yeah, it'd break when the handles is in a role, at least if we don't make further changes to compensate for that :)
psch i think it was about 'does Positional' and 'has @.a handles <AT-POS ...>'
have the RT, i mean 09:39

gfldex moritz: your post made me think of what will remain of me when I am not. There is pretty much nothing left of the original Linux or Unix source code. But what about man-pages? Does writing docs made me immortal (for a value of immortal that depends on how long humans use english)? 11:05
moritz gfldex: and, is it really important that something will remain of you, after your death? 11:06
you won't care anymore
the idea is nice, but why?
gfldex For the I-am-me-problem it has relevance. 11:07
moritz gfldex: also, today's Linux evolved from Linux 0.01. Even if none of the code of Linux 0.01 remains in today's kernel, its inheritance in terms of project/community still influences Linux today
(where by Linux 0.01 I mean the first code that Linus wrote, even if it never had that version tag) 11:08
gfldex I can refer to something persistent that others can refer to, proving that I am not imagining me (for low values of proof).
moritz others can refer to your body, or to your lines on IRC just the same 11:09
moritz is being obnoxious today
gfldex also humans seam to like grave stones, what is a completely pointless endeavour for the person whos name is on it.
[ptc] it's nice to have the feeling that one has made a contribution to society etc., at least while one is still "here", however afterwards it only probably matters to those left behind 11:10
moritz: nice post btw :-)
moritz [ptc]: thanks

13:58 araujo_ left
ZoffixW Next step would be to make it know which stresstest *file* hits the code, but currently that'd take forever to run. Volunteers to make this parser generate separate reports per input file per run are needed: github.com/MoarVM/MoarVM/blob/line..._report.p6 13:58
So that way, it has to read the annotations (that takes forever) just once and then just would go in and generate separate reports for each stresstest file and then the bot would just look up which files hit a particular line :) 13:59
And perl6.WTF/ has core coverage now :)

xdxdxd How would I organize a ton of retrievable information on different pokemon into a separate perl6 file 17:59
17:59 Ven_ left
xdxdxd oh 18:02
I'd use a map, right?
avuserow hi xdxdxd, depends on what information you want and how you want to retrieve it. you might be able to get away with a file that defines and exports some hashes or objects, or maybe something like SQLite would be more appropriate
xdxdxd It will be nearly 2,000 lines or so of information on each individual pokemon 18:03
Would SQLite be more suitable for that?
timotimo SQLite is quite fantastic in any case 18:04
you can use DBIish to use it from perl6
avuserow SQLite and other databases would excel if you had a bunch of relational data beyond just "pokemon 1 has weight X and height Y", since you could write SQL queries allowing you to ask "what's the most powerful move learned by normal types", or similar 18:07
you can answer the same question if the data is stored in p6 data structures, but you'll have to write the iteration as perl6 rather than SQL. may or may not be better. 18:08
xdxdxd I'll definitely be going with SQLite then
thanks for the help

jnthn No, and there's an explanation here: docs.perl6.org/type/IO$COLON$COLON...hod_Supply
timotimo when a string is received, perl6 has to keep the last character around in case the next char received is a combining character
if there's a newline or some other control character at the end, we know there can't be a combiner 18:17

smls jnthn: Will you expose a complex system of IO layers to userspace, like Perl 5? ;) perldoc.perl.org/PerlIO.html 18:40
18:42 cdg left
jnthn smls: Yeah, the idea is that you'll be able to having something implement the Encoding role and then pass it to the :$enc parameter (and if you pass a string as today we'll resolve it to an Encoding object first) 18:43
smls neat
jnthn In general, the VM-level I/O will deal in binary, and we'll pull the "management" of I/O up to the Perl 6 level, which should make doing various tweaks easier 18:45
The various built-in encodings will still use VM-provided implementations.
But by taking them apart from I/O, you'd be able to re-use them when you have bunches of bytes and want to toss them into a streaming decoder.
(Like the body of a HTTP request after you've looked at the headers to know what encoding it needs) 18:46
18:47 setty1 left
smls You mean you can switch encodings in the middle of reading from a socket or filehandle? 18:47
jnthn Well, more that you'll get bytes in and coordinate decoding of them 18:48
smls ok 18:50
Is CR/LF newline-conversion considered separate from encodings? 18:51
18:53 sjoshi joined
jnthn In current plans I've got it as a parameter given to the decoder 18:54
18:54 cpage_ left
jnthn While "separate pass" is architecturally pretty it's performance ugly. 18:55
Though I suspect for user-space encodings somebody will end up putting a role on CPAN that you can just use and it will do it as another pass. 18:56
18:56 sjoshi left
jnthn Since a decoder is just an object, though, there's no reason you can't nest them, delegating to an inner one then acting upon what it produces. 18:58
So I guess you can recreate IO layers that way ;)
