lambd0x Hello everyone! 00:31
timotimo hey you 00:32
lambd0x timotimo: \o/
timotimo: how're doing?
timotimo today was not a good day, but otherwise all right
how are you?
lambd0x fine, just having some doubts using file in perl6 00:33
timotimo "file"? 00:34
lambd0x timotimo: basically yes... I'm trying something that I used to do all the time in C...
to have a config file and that would provide parameters and also input to the program.. 00:35
but I'm not being able to get the hold of a handle that just firstly reads two numbers to some vars and considers the rest of that file as input. 00:36
timotimo what are you tryung?
like, are the first two numbers in a line of their own? 00:37
lambd0x To multiply two Matrixes. I'm providing first the two numbers to know the order of the first matrix then its contents and in the same file the next two numbers of the second matrix and then its contents 00:38
timotimo: yes.
timotimo then you can just .get it line by line, can't you?
lambd0x timotimo: yes, but if I do that. how can I say read it up to that point? For the contents, and then again read another two and repeat the process 00:39
timotimo depends entirely on how you know how much content there is 00:40
lambd0x those two files express the order of a matrix and therefore if I have a 2 2 -> 4 numbers should be read
timotimo are the values in the matrices encoded as human-readable numbers? are they just 32bit floats or something? 00:41
timotimo is it still line-based? a certain number of numbers per line? 00:41
lambd0x timotimo: they're integers separated by lines acording to their order (in matrix form) I managed to save them such that would be easily read by performing a loop with the order numbers 00:42
lambd0x basically I wanted a way to read a number from the stream and keep the handler to afterwards read another number that I would be able to control somehow... 00:43
timotimo for ^2 { my $matrixorder = +$file.get; my @matrixlines = $file.get xx $matrixorder; say @matrixlines.perl } 00:45
try that
lambd0x timotimo: ^2 means? 00:46
timotimo "up to two", in other words 0..1 00:47
or in this context, "twice"
lambd0x timotimo: You gave me an idea. I'll work it out from here. Thanks :) 00:52
timotimo YW
lambd0x timotimo: nice this ^n operator...
timotimo it's cool how the xx operator will execute something twice
m: (say "hello") xx 4
camelia rakudo-moar 328402: OUTPUT«hello␤hello␤hello␤hello␤»
timotimo m: (say rand) xx 4 00:53
camelia rakudo-moar 328402: OUTPUT«0.352484542036053␤0.867382257469645␤0.345555578673232␤0.721099736714825␤»
timotimo and each time it's a fresh execution, too. so it's like a little loop
lambd0x indeed
lambd0x timotimo: ^$somevar-1 will execute ^$somevar first and then -1 over it or none at all? Had something similar here that didn't work. Changed to 0..$somevar-1 01:04
timotimo yeah, the precedence of .. is very tight; you can - 1 a range and it'll be "shifted" one to the left 01:05
m: say ^5 - 1
camelia rakudo-moar 328402: OUTPUT«-1..^4␤»
timotimo m: say ^(5 - 1) 01:06
camelia rakudo-moar 328402: OUTPUT«^4␤»
timotimo the precedence of ^ is very tight, i meant to say 01:07
lambd0x timotimo: ah good to know :) 01:08
m: say ^5 + 1
camelia rakudo-moar 328402: OUTPUT«1..^6␤»
lambd0x that's nice :P 01:09
timotimo yeah, that's how you get "from one" instead of "from zero" while still keeping the ^
AlexDaniel m: say 1..^6 # if you want to keep ^, why not do it this way? ;) 01:14
camelia rakudo-moar 328402: OUTPUT«1..^6␤»
timotimo *shrug*
AlexDaniel m: say 2..^10 / 2 01:15
camelia rakudo-moar 328402: OUTPUT«2..^5.0␤»
timotimo that's tighter than ..^ apparently
AlexDaniel is it supposed to be this way? 01:16
timotimo *shrug*, i usually go for parens with this sort of thing
AlexDaniel it makes sense, I think. But it is somewhat inconsistent
unmatched} GIGO 01:22
wc
unmatched} I love these answers for person asking for source code of split :) www.reddit.com/r/perl/comments/4ww..._of_split/ 01:37
I think P6 being written in P6 is a very real strength, although I see the inevitableness of it being rewritten in NQP 01:38
timotimo actually, larry is hoping we'll be rewriting it completely in perl6 at some point 01:41
so .. the opposite of what you're fearing :)
unmatched} As much as I believe in TimToady's power of though, I doubt we'll one day just go "you know what, let's make this method 30 times slower" 01:43
(that's based on my observation of lizmat++'s stellar work of rewriting stuff in nqp and the speed benefits reaped from such conversions) 01:44
gfldex the idea is not to have to make it 30x slower
timotimo right. the idea is that perl6 code at one point will optimize as well as nqp code does now
geekosaur ^ optimization is very much a work in progress, brrt was charting out more optimization work earlier today even 01:45
unmatched} "one point"? What's stopping us from doing it now?
geekosaur people, available time?
timotimo yeah, it's not trivial 01:45
are you interested in maybe implementing escape analysis for moarvm?
geekosaur welp. that'd certainly be an intro to why optimization is hard :) 01:46
unmatched} timotimo: sure 01:46
timotimo: if we start from the point that I don't know wtf "escape analysis" even is :)
timotimo cool. but i'm afraid it might require a bit of design work, too
well, there's wikipedia and lots of papers for that 01:47
timotimo basically, analysis of "will this value stay alive past a certain point? perhaps it gets assigned to something, or somehow referenced or something" 01:47
because once you know an object will definitely become unused at a certain point, you can either allocate it on the stack instead of on the gc-managed heap, or even leave out the allocation partially
unmatched} Are those papers free to read? 01:48
timotimo i bet many are
escape analysis was probably invented like 80 years ago
unmatched} Cool. I'll look around then.
:o
timotimo you'll be interested to know that moarvm's bytecode is in SSA form composed of "basic blocks" (only during spesh, but escape analysis is spesh-only) 01:49
unmatched} Challenge accepted! :D 01:50
timotimo wow
there's a branch already that has a tiny bit of the escape analysis work 01:51
you'll be wanting to read the header files inside src/spesh/, especially graph.h and facts.h
timotimo and src/core/oplist is also interesting 02:02
unmatched} Thanks. I'll start researching this once I'm done with the internals course (should be by end of week). 02:07

SmokeMachine____ I just needed to read the error message! I'm sorry! 03:45
geekosaur cached is marked experimental for a reason, it's rather broken and not a high priority to fix iirc
SmokeMachine____ Thanks 03:48
TimToady thinks experimental should be renamed to MONKEY-AROUND or some such 03:51
TimToady or at least be aliased, like "use nqp" 03:59
ugexe just like real animal testing you never know if your work will die horribly for unknown reasons 04:00
TEttinger monkey all the things 04:11
then when perl 6 gets bought by microsoft it suddenly changes to MONEY_AROUND and MONEY_SEE_NO_EVAL
TimToady embrace and MONKEY_BUSINESS 04:14
I suppose it's more like a monkey trap 04:20
Xliff TimToady, would that be MONKEY_EMBRACE_AND_EXTEND 04:47
Next thing you know MONKEY_ASTROTURF will show up, and then it's game over. 04:48
TimToady Look! That cloud over there is a MONKEY-CLOUD! 04:52

AlexDaniel gfldex: you mean that rakudo is right here and I must use a comma? If so, OK then, but we should probably document it as p5→p6 pitfall 06:01
Xliff Ah. Yeah. 06:02
I've run into that.
Good to know about the comma trick. I thought I was going mad.
gfldex AlexDaniel: we should document it in general (looking at it right now)
AlexDaniel gfldex: want me to create an issue on github?

no, better doc it in p5->p6 right away 06:03

Xliff Aha! 06:06
AlexDaniel, ^^ that should probably also be documented.
AlexDaniel /o\
ah no, it's right \o/ 06:07
I still don't get it. Why can you ommit the comma in ｢my ($x,)｣ case but without “my” you must use it? 06:09
brrt hey #perl6. seeing as we can capture the signature of a routine, and that types are objects, i think we should be able to write something like Buf.unkpac(int $x, num $y) and have it automatically do the right thing 06:14
not as flexible as string-unpack, though
also, i just realised that the whole 'serveless architecture' thing is basically re-warmed CGI 06:15
Xliff LOL 06:17
brrt, can I steal that?
brrt ideas? no 06:18
you can copy them though
Xliff Then I shall do so mercilessly...... with your permission, of course.
But then that's not "mercilessly" innit? Hrm.
brrt hmmm
no
Xliff Damn. Sounded good, though.
brrt well, have hun with it :-P 06:19
Xliff hun?
I want to copy that tidbit... not hug it!
=)
AlexDaniel: I'm thinking assignment via "my" is different than assignment without it. At least that's how I'm rationalizing it. 06:21
AlexDaniel Xliff: my rationalization stopped somewhere after “t” in WTF. Like… I do understand that maybe we can't have it to dwim without ｢my｣, but then why the trailing comma is not required if you use ｢my｣? 06:23
AlexDaniel anyway, I'm submitting an RFC rakudo ticket. Feel free to throw your tomatoes at me there 06:24
Xliff AlexDaniel, if I throw anything, it will be lots in with you. 06:27
You have no idea how many hours I wasted on that but on my first P6 project.

jkramer unmatched}: Neat :) 14:08
One more question: I have a list of words and want to match any of them in a regex, is there a way to do that? I mean instead of: /foo ( a | b | c) bar/ I'd like to do: my @x = <a b c>; /foo ( one-of @x ) bar/ 14:10
unmatched} /foo @x bar/ 14:11
jkramer Ha, beautiful :D 14:11
grondilu <@your-list> should work 14:12
oh it was answered already. my bad.

unmatched} It's really annoying to type '($/)' on actions all the time... You think it's possible to do a trait on the class or something like that that would make the signature ($/) by default/ 14:35

unmatched} :) 14:45
unmatched} marks it as a weekend project 14:46
jnthn 1) Implement a trait that mixes some role into the meta-object of the class to mark it. 2) In IMPORT, mix into $*W to override attach_signature (be sure to callsame up to the original). 3) Check the first arg is a Method object. From the signature, grab the nominal type and see if it's a class marked with the trait. If so, meddle with the Signature to include a $/ Parameter object 14:51
Or something along those lines. There's probably something I didn't think of :)

unmatched} Anyone done the internals course? How can I make my compiler read a file, rather than me having to type everything all the time in REPL? 15:37
I got this compiler, and I get the error "Too many positionals passed; expected 0 arguments but got 1": gist.github.com/zoffixznet/521f1eb...62eb72d35a
jnthn Odd, it looks like it actually made it all the way into running the code from the file before failing 15:40
Assuming the file you can is in training/code ?
unmatched} jnthn: Yeah, the file training/code is the file with code and it just has one line: puts "Hello world" 15:41
which works, if I type it in repl
jnthn What happens if you pass --stagestats before the filename?
unmatched} jnthn: gets up to moar: gist.github.com/zoffixznet/78a6f98...91f4409639 15:42
jnthn Which means it compiled the code and is trying to run it at the point it fails
Try --target=ast and see if the constructed AST looks sensible 15:43
unmatched} I think so: gist.github.com/zoffixznet/6dfdaee...3e996e4b43 15:44
jnthn Yeah, looks OK to me also 15:45
--target=mast shows what it's getting compiled into
Also you can --target=ast without a filename to see if what you get in the REPL is any different 15:46
unmatched} I get the same thing
mast also seems to be the same: gist.github.com/zoffixznet/73bd3aa...95ffeabd02 15:47
pmurias I get different ast for the code in that gist 15:48
jnthn ./nqp-m training/compiler-basic --target=mast training/code st
What's that "st" on the end?
pmurias got correct ast when passing a file instead of -e 15:48
unmatched} Just a typo. Here's the output without it: gist.github.com/zoffixznet/e84f64b...cc71df9571 15:49
pmurias the error you get is the program you generate not accepting the command line arguments 15:51
jnthn I think that typo was the problem though? 15:52
It was passing the extra command line arguments to your program but your program didn't accept them
unmatched} Running this still fails: ./nqp-m training/compiler-basic training/code
where compiler-basic is the compiler and the code is the code I want that compiler to run. 15:53
pmurias: OK. I guess I'll just cat the code then
Actually, I think that won't work 'cause REPL treats each line as new one :/ 15:54
new program or whatever... Wasn't working right when I taught the compiler to assign variables.

perlpilot lambd0x: huh?
unmatched} lambd0x: well, I've still no idea what you're trying to do. So... I give up
lambd0x ok. I want to read lines from a file up to some point while saving it to a bidimensional array and then repeating the process for the other part of the file 16:22
perlpilot lambd0x: how about we start with this: my $n = get; #`{ the number of element is the first line }; my @a = lines[^$n]; my @b = lines; 16:25
lambd0x: does that help?
perlpilot lambd0x: or since you keep saying "bidimensional array", maybe you want something like my @a[$n/2;$n/2]; |@a = lines[^$n]; # ?? 16:26
perlpilot I dunno 16:26
lambd0x hahaha
perlpilot that's a curious response 16:27
lambd0x perlpilot: You see I want to multiply two matrixes. They're in a file generated by another code of mine.
perlpilot: first number is the order of matrix 1. then its contents it should read up to order lines storing it 16:28
but just storing lines wasn't working because then I couldn't get their index for each element and multiply it with the following line of the second matrix 16:29

Nex6 have question, just starting with Perl6; starting by write stuff. I am trying to use "run" to run "ping" 17:14
see: my $results = run 'ping', $line, '-c 1','-v', :out;
unmatched} Nex6: '-c 1', should be two items
Nex6 and the proc capture: my $cap = $results.out.slurp-rest;
unmatched}, ok 17:15
how can i test for failure?
unmatched} I guess it works both ways :S weird
Nex6 yea it works well, but now how can i test for a fail? 17:16
unmatched} fail of what?
Nex6 if i ping say 100 hosts i want to know which ones worked and which ones failed
ilmari udoes ping report that via the exit code? 17:17
Nex6 now, it is sending the shell output to a log file
unmatched} Nex6: that's one way, but there may be a more robust alternative: $results.out.slurp-rest ~~ /$<errors>=\d+ \s+ 'errors'/; say $<errors> && $<errors> > 0 ?? "This one is a fail" !! "not a fail" 17:18
The manpage says one can use the error code to determine whether the host is alive, but .exitcode gives 0 for me at all times 17:21
unmatched} Unless I don't subscribe to :out 17:22
Another bug looks like ~_~
Nex6 here is the output when i added your line:
------> ?? "This one is a fail" !! "not a fail"⏏<EOL>
expecting any of:
infix
infix stopper
postfix
statement end
statement modifier
statement modifier loop
unmatched} Well, it works in the eval above :D 17:23
unmatched} Do you care if you get ping's output in the terminal? You can just use this: say run("ping", "10.10.10.10", "-c", "1", "-v").exitcode == 0 ?? "Good" !! "Fail!" 17:25
unmatched} Technically, you're supposed to be able to add :out and suppress the output, but for some reason then the .exitcode stops working 17:25
Nex6 no i am only using the shell output to see what its doing i want to run it as cron, and report bad hosts 17:26
nine unmatched}: you have to close :out before asking for the exit code
unmatched}: as long as .out is open, the process is still running and does not have any exit code
unmatched} Looks like I have to slurp-rest it too :S 17:29
Nex6: this works: given run "ping", "localhost", "-c", "1", "-v", :out { .out.slurp-rest; say .out.close.exitcode == 0 ?? "Good" !! "Fail" } 17:30
jdv79 why do we have slurp-rest again?
unmatched} again? 17:31
jdv79 the reasoning i mean. couldn't it just be slurp?
timotimo because slurp also closes the filehandle 17:32
whereas slurp-rest doesn't
perlpilot it's still one of those things that bothers me too.
(irrationally, but still)
jdv79 the docs don't mention closing
perlpilot "slurp" fits my brain well. "slurp-rest" feels icky (because most times where I *have* to use it, I want it to be called "slurp") 17:33
Nex6 yea, under proc it does say close it 17:34
thats doesn't say
timotimo jdv79: well, you don't run slurp on a filehandle, right? 17:35
jdv79 yeah, that's true. 17:39
i guess i can sorta seen the use for the odd name. still odd.
*see
timotimo yes, it's kinda odd 17:40
however, would you expect .slurp - given its name and how the other slurp works - to seek to the beginning of a file first?
jdv79 not me but i can see someone thinking that 17:41
a fh implies state
what's wrong with just more read() multis instead of slurp*? 17:42
i guess we favor more names for disinctness these days 17:43
Nex6 this is what works: 17:54
my $results = run 'ping', $line, '-c', '1', '-v', :out;
if $0 != 1 {
say "$line Failed to respond!!!!!!!"
};
in a for loop
unmatched} $0 ? :S 17:55
Nex6 Perl6 v= rakudo-star-2016.04
unmatched} m: say $0
camelia rakudo-moar 5dd91d: OUTPUT«Nil␤»

jdv79 so that would "work" as long as it didn't not work.
haha
i think you want $!, no? 17:57
unmatched} Nex6: what made you use $0 in there?
Isn't that just for caught exceptions? 17:58
And anyway, based on nine++'s explanation, no variables would work there, because the process is still open
Nex6 the line you gave me didn't work, i remember the was a a symbol for return code, and looked it up. I used to do perl many many years ago now spent all my time in other languages i guessd
unmatched} Nex6: you're confusing Perl 6 with our sister language Perl 5. 17:59
jdv79 $0 in p5 is the prog name
Nex6 I think early perl 5/4 was an early language of mine
but have not used it since
unmatched} Right, Perl 6 is very different.
perlpilot very very VERY different :) 18:00
geekosaur $? is what you wanted. $! is errno
(per;5)
in perl6, you don't want either.
Nex6 hmmm , so don't use $0 in Perl6 what should I have used? 18:01
unmatched} The code I showed :)
What do you mean by "didn't work"?
Nex6 ok will play with it thanks, have to go 18:02
will be back later
geekosaur docs.perl6.org/type/Proc docs.perl6.org/routine/run
Nex6 I don't have the output screens but i have it commented
be back in about an hour 18:04
unmatched} chuckles 18:25
A work order came in for a broken button on the website. I notice it's because the product code has a '+' in it and it isn't percent encoded. So I forward this to The Right People, saying their code is failing to percent-encode and that the + should end up as %2B in the URL... They just fixed it. I'm looking at the fix and it amounts to this line in about 30 places: $product-number.subst('+', '%2B') 18:26
Guess we'll wait until we get product numbers with > in them ^_^
timotimo ;_; 18:28
mspo at least they used a direct replce and not a regex 18:31
timotimo but it's cool they're writing perl6 code 18:36
(no other explanation for $product-number having a dash in it) 18:37
geekosaur "it amounts to this line" --- I took that as meaning they translated to p6 :) 18:38
unmatched} Yeah, I translated to Perl 6. Original is an awful BASIC-based abomination that should not be powering any websites. 18:39
Xliff I echo (timo x 2) -- ;_; 18:40
Xliff It's either that or repeated headdesks. 18:40

timotimo If the entire recorded history of humanity could fit in a single megabyte, then Babel alone would consist of SEVENTEEN times the entire recorded history of humanity. Just so that we can avoid writing JavaScript. 21:20

harmil_wk I was wondering, how do I get examples added to the examples.perl6.org/categories/parsers.html area? 21:26
That string parser I posted to reddit would be useful there, I think.
gfldex harmil_wk: fork, clone, edit, push, click PR 21:27
timotimo hoelzro: are you sure it's satire? 21:28
because the exports.guy thing is definitely in there
github.com/babel/babel/blob/f36d07...ode.js#L33
hoelzro wat 21:30
did they add that because of the post?
timotimo yes 21:31
github.com/babel/babel/pull/3641
El_Che is there something out there to easily count line of codes to check how many of them have been ported (e.g. comparing the "done" classes with the "still-to-be-ported"? 21:32
or put it differently, has someone seen that kind of badge on github?
hoelzro ... 21:33
that's just...so silly of the babel devs
oh well, it's not my project
¯\_(ツ)_/¯ 21:34
El_Che: what do you mean by ported lines?
El_Che hoelzro: let's say the original (perl5) project has 40 classes, and I already ported 3 to perl 6. So the port is 3/40 on the way 21:35
El_Che I wonder if there is something more finegrained like line of codes 21:35
hoelzro ah, I see
El_Che it's easily silly to do
but I wonder if there are github badges out there 21:36
hoelzro El_Che: my silly comment was regarding //github.com/babel/babel/pull/3641
Xliff HAHAHAHA! ROFLMAO!
hoelzro El_Che: my silly comment was regarding github.com/babel/babel/pull/3641
Xliff That post is awesome.
El_Che hoelzro: yeah, I got that :) 21:37
hoelzro ok =)
Xliff And yes... its got to be satire.
El_Che nice to clarify though :)
Xliff Please tell me it is satire.
unmatched} :)
Xliff reaches for the padded desk.... Just In Case.
unmatched} It is
Xliff finally understands the exports.guy references. 21:39
But seriously..... Fieri? That hack?
Couldn't they have found a better guy?
=)
Xliff "Conclusino" <- The final nail 21:40
pmurias The babel folks actually putting a "Guy Fieri" picture in the source doesn't make a very good impression about their project :/ 21:42
Xliff pmurias, I gno write!!!
Didn't I just say that?
hoelzro pmurias: yeah =/ 21:43
profan it was spawned by a certain blogpost i believe, that was poking fun at dependency hell in js land
hoelzro profan: do you know which?
profan moment, lol
hoelzro I was curious to see if it was just for fun, or if there was some underlying point
Xliff Yeah. I gotta read that one.
Well, dependency hell is universal.
profan medium.com/friendship-dot-js/i-pee....z4l2qfhpk
it's a bit on both sides of the fence, but i believe it came from there :p 21:44
Xliff profan: Er. That's the post we are talking about.
profan oh, woops 21:44
unmatched} pmurias: it's satire. There's no picture :)
Xliff profan: It's cool! =) 21:45

unmatched} geekosaur: no, Perl 6 in general. I started this tiny ass program 4 hours ago. It should've taken 20 minutes to finish. I first wasted time with that .^compose in mainline bug, then this "no candidate" thing that appears to happen when the Proc fails (because that makes a lot of sense somehow?), then zef not seeing the latest and greatest module release, and now... after I finally managed to run the perl6 I 23:03
want to run, it's complaining about a missing module because that perl6 apparently doesn't know where the modules are installed at.
unmatched} throws tables around then opens another beer
I just don't think I'm writing that much of an arcane code to be constantly bombarded with bugs, and quirks, and missing information. 23:04
And a lot of Perl 6 feels like a hack. I know some people poo-pooed Zeframs talk, but I do think he has a point about too many features and their interactions. 23:05
Even the .words/.lines issue above can be tagged with that
</rant>
( this talk I meant www.youtube.com/watch?v=fZZBYRT5Ghc ) 23:08
timotimo maybe Proc doesn't initialize its out pipe (i.e. sets it as the Pipe type object) when the run can't work? 23:11
and then you get "can't call slurp-rest on an undefined object" with a message that doesn't tell you as much
timotimo and you should be able to just ./perl6-m in a rakudo checkout, or find the relevant install/bin/perl6-m 23:12
unmatched} Yeah, the IO::Handle is a :U and I get the NoCandidate exception because all candidates are a :D gist.github.com/zoffixznet/93c1917...342712c570 23:13
