ckraniak | So I know y'all were saying if I wanted to load a function pointer into a CStruct I needed to nativecast to pointer | 00:59 | |
Only missing bit now is I don't know how to define a function I can do that with in Perl | |||
Can I tack an "is native" and give it an actual function body and expect it to behave? | 01:00 | ||
Basically how to define a callback in Perl that C can use, or if that is eve a thing | 01:01 | ||
01:08

lookatme | the callback is normal function in Perl 6 declare with sub | 01:11 | |

nadim | can't. the objects are build somewhere else, all I can do is pass roles | 06:27 | |
lookatme | I'm not get it, what are you trying to do ? | 06:28 | |
nadim | one of the roles I am passing has $.x; when the object is created I want $.x to be set to, say, 42. | 06:30 | |
06:30
dubi0us left
|
|||
nadim | the role, I have, uses $x to display a limited part of a string. if I do not set $.x, the whole string is displayed | 06:30 | |
the only way I see is to have a derived role which will set $.x | 06:31 | ||
remember that I do not have the object, just roles I can pass | |||

nadim | I have two pieces of code. In the first one I had the object so I could $o.x = 42. In the second code I call a sub which contructs a special object that can take roles. | 06:38 | |
as a shortcut I copied the whole role but it not very OO | |||

yes, but | |||
arguably, it should not be necessary | |||
piojo9 | Haha. Just looking for advice on the best environment for learning and fairly simple (100-1000 line) scripting | ||
brrt | i don't think we're in the part of the cycle where we have self-sustaining quality checks | ||
i.e. like perl5 has | 08:25 | ||
we have a test suite, but it's not nearly large enough | |||

pmurias joined
|
|||
moritz | the p5 developers regularly smoke-test most of CPAN with their bleadperl | 08:26 | |
because their core test suite alone isn't enough either | |||
brrt | that's mostly what i mean, yes | 08:27 | |
a heavily-used, mature language can afford that | |||
now rakudo is one hell of a test suite by itself | |||
but it's nowhere near everything | |||
pmurias | brrt: rakudo is written in NQP | ||
brrt | true | 08:28 | |
but for MoarVM that's still quite good | |||
lookatme | :) NQP syntax is more functional style | ||
pmurias | brrt: re afford that, is running tests for all our modules too expensive for Perl 6? | 08:29 | |
brrt: or do you mean that we don't have enough modules to test everything? | 08:30 | ||
gfldex | last time I checked it took about 8h on a not so fast host to test the whole ecosystem | 08:31 | |
it seams AMD is making CPUs for us :) | |||
nadim | Am I right to assume that a Socket going out of scope will have it's close method called? | 08:35 | |
08:36

|
|||
moritz | only when the GC collects it | 08:37 | |
LEAVE $socket.close if $socket; | |||
lizmat | or: | 08:40 | |
LEAVE .close with $socket | |||
brrt | brrt: more the later than the former | ||
i don't expect that running a cpan smoke test is very cheap for the perl5 hackers | |||

araraloren | Perl 6 's IO performance is 10x slower than Perl 5 | 12:32 | |
timotimo | what code are you timing? | 12:33 | |
moritz | araraloren: did you measure comparable things? Like actually doing the UTF-8 encoding/decoding in Perl 5 that Perl 6 does by default? | ||
jnthn | That's not generally true 'cus I got one quite common case (reading a UTF-8 file line by line) *faster* on Friday :P | 12:34 | |
12:35
zakharyas joined
|
|||
timotimo | might have to check whether you've got buffering on the perl6 side or not, because perl5 does buffer | 12:35 | |
and the difference between buffered and direct can be huge | 12:36 | ||
12:36
gregf_ left,
dubi0us left
|
|||
jnthn | That too; for file output, then :buffer passed to open can make quite a difference. | 12:37 | |
We'll do that by default for non-tty at some point in the near future | |||
araraloren | I have one unix format file, how can I improve my program performance: for $file.IO.lines { my @cols = .split("\t"); @db.push([ @cols[0].Int, @cols[1].Int, @cols[2] ]); } | ||
I read file like above | |||
timotimo | can you give us a little one-liner that would generate a typical piece of input file at a reasonable size? | 12:38 | |
araraloren | It's like `<11 number> \t <11 number> \t <4 number>` | 12:39 | |
1300012000013000129999022 | 12:40 | ||
timotimo | okay so kind of like (10000000000..99999999999).roll(2).join("\t") ~ "\t" ~ (1000..9999).roll | ||
how many lines are you working with? | |||
araraloren | It's about thirty thousand line | 12:41 | |
sorry | |||
three hundred thousand | 12:42 | ||
And I have SSD | |||
timotimo | how long does it take on your machine? | ||
araraloren | 12~13s | 12:43 | |
timotimo | ok that's good | ||

timotimo | profiling now | 12:45 | |

dubi0us joined
|
|||
timotimo | okay it's spending 36.6% of its time inside split and 16.6% of its time inside the Int method | 12:46 | |
araraloren_ | jnthn, Hi, I found a IO Pipe problem. When use `morel` look through the result, press q will cause rakudo complain : Failed to write bytes to filehandle: Broken pipe | 12:47 | |
12:47
araraloren left
|
|||
timotimo | on my machine it also takes just 10 seconds | 12:47 | |
araraloren_ | ls /usr/bin -al | perl6 -e '$*IN.Supply(:size<8>).tap(&print)' | more | ||
timotimo | there's been a ticket discussing this very issue recently | ||
araraloren_ | jnthn, here is the command ^^^ | 12:48 | |
OH, you mean the broken pipe ? | |||
jnthn | signal(SIGPIPE).tap: { exit(0) } | ||
If you want to silently exit on such things | |||
timotimo | interestingly, STORE, i.e. putting the result of .split into the array, takes 20% of the time inside the loop block | 12:49 | |
12:50
dubi0us left
|
|||
araraloren_ | ok, seems like add try around it also work | 12:50 | |
while(<KK>){my @abc=split "\t",$_; | 12:51 | ||
push @kk,\@abc; | |||
} | |||
and this is perl 5 code | |||
timotimo | using substr three times (since you know the lengths of the numbers up front) reduces it to 7.5 seconds | 12:52 | |
12:52
itaipu joined
|
|||
timotimo | you're not numifying the values in the perl5 version? | 12:52 | |
without the two .Int i get down to 4.5s | 12:53 | ||
12:53
ambs joined
|
|||
araraloren_ | timotimo, but I will compare to Int after read over | 12:54 | |
timotimo | OK | 12:55 | |
if your ints are the same lengths every time, maybe doing string comparison is cheaper than intifying | |||
araraloren_ | will try it | ||
jnthn | Even then, == in Perl 6 will compare them as numerics late | 12:56 | |
*later | |||
So there's no particular reason to do the conversion earlier | |||
timotimo | except if you keep one side of the comparison the same every time and that's a string that gets intified over and over again :) | ||
jnthn | Well, true :) | ||
Then it makes sense :) | 12:57 | ||
araraloren_ | Okay | ||
jnthn | Though still changes the cost of the work in the loop we're comparing | ||
timotimo | i've had some benchmarks *terribly* slow because they grabbed the "number of times to run" from @*ARGS and it was a string that was being compared to in the main loop a bajillion times | ||

araraloren_ | But the whole time of Perl 5 only cost 0.9s | ||
Altreus | can I do substr(Str, $start) such that it returns the whole string if it is not $start chars long? | ||
araraloren_ | yeah you can | 14:32 | |
Altreus | uh | ||
I mean the empty string | |||
brain fart | |||
Currently it tells me off | |||
"Start argument to substr out of range" it says | |||
araraloren_ | empty string ? | ||
stmuk | mspo: ok hang on I'm nuking and starting from scratch | ||
Altreus | Yeah if the string is not N chars long then I want substr(Str, N) is to be no chars, not an error | 14:33 | |
jnthn | Altreus: It's probably a Failure, so you can just // '' afterwards | ||
Altreus | tak | ||
ilmari | m: say substr("foo", 4) // "too short" | ||
camelia | too short | ||
araraloren_ | m: say substr("foo", 4) | ||

araraloren_ | Where is the exception ? | 14:34 | |
m: say substr("foo", 4) // "too short" | |||
camelia | too short | ||
Altreus | who said exception? | ||
jnthn | araraloren_: It returns a Failure (lazy exception) | ||
If you call .defined it's disarmed | |||
mspo | I also wish I understood this error: Serialization Error: missing static code ref for closure 'BUILD' | ||
araraloren_ | okay, cool | ||
Altreus | I like it more now that I'm aware of it | 14:35 | |

stmuk_ | yeah I agree | 15:21 | |
mspo | I'm a little afraid that if everyone else, including lib developers, are just using zef all the time otherwise | 15:22 | |
install-dist.pl might always be playing catch up or drifting out of sync | |||
but I probably don't understand that they're both just front-ends to Comp Unit stuff | 15:23 | ||
ugexe | lib developers shouldnt be using install-dist.pl | ||
install-dist.pl is essentially a convience to writing a 1 liner to do the same thing since all the class names are so long. everything is just using CompUnit stuff to get the job done, there is nothing to catch up to | 15:25 | ||
stmuk_ | does anything actually use it? | ||

Zoffix | timotimo: once it gets parsed written in one style, the other style will just used cached version. | 18:14 | |
That's the bigger problem with the issue: a pure statement's value can change depending on what type of code got parsed earlier in the program. | |||
timotimo | oooh | 18:15 | |
so that's why | |||
hm, but how does it figure out those two should be the same num value? they aren't string-equal, and they're also not going to be numerically equal? | 18:16 | ||
18:16
dubi0us left
|
|||
Zoffix | Don't know. I never investigated it. | 18:16 | |
Well, actually, I don't know if it's actually using the cached value; that's just the apparent effect and earlier parse affects later values of unrelated statements | 18:17 | ||

raschipi | timotimo: the expoent is a signed number, so the string representation can be turned into the float in multiple ways. Compare mantissa 0.1 with exponent 0 with mantissa 1 with exponent -1. So that might be where the differences come from. | 18:21 | |

ckraniak | I am on Win 7 (6.1) and it returns 6.3 and am not sure if it's failing to report OS properly or if it is doing something else | 19:06 | |
andrzejku | hey people | 19:07 | |
geekosaur | ckraniak, it could be using build time info | ||
that said, windows complicates things with e.g. 32 bit bins on a 64 bit system running in a VM which may be booting a different version :/ | 19:08 | ||
moritz | and that the internal and the marketing versions also often disagree | 19:09 | |
andrzejku | do you think it have a sence to write another HTTP Perl6 server?:P | ||
ckraniak | Build version is what I was thinking | ||
moritz | andrzejku: if it supports HTTP/2, sure | ||
ckraniak | Although I had the impression $*DISTRO was meant for runtime checking | 19:10 | |
geekosaur | arguably $*DISTRO should be runtime and $?DISTRO should be build time, or something like that | ||
lizmat | on Win, it gets the version information from $*VM.config<osvers> | ||
raschipi | ckraniak: It's reporting the NT version, which is 6.1 | ||
andrzejku | moritz, that was a plan | ||
moritz, however we and my friend we think more about | 19:11 | ||
raschipi | Source: en.wikipedia.org/wiki/History_of_M...er_2008_R2 | ||
ckraniak | raschipi: it is reporting 6.3 though | ||

TEttinger joined
|
|||
geekosaur | on theone hand that's arguably an abuse of the $? sigil, on the other it does make the point that the $? one is from a different context (just, the wrong "build tme" :) | 19:11 | |
andrzejku | moritz, Perl6 server which will share wasm perl6 interpreter which should interpret perl6 code and qml frontend | ||
do you think it is good idea? | |||
raschipi | I think service packs upgrade that number. | 19:12 | |
ckraniak | Shouldn't | ||
VerifyVersionInfo documentation / invocation explicitly separates service pack info | |||
raschipi | For example, for me it returns 4.9.0, which is my kernel release. It should do something similar on windows. | ||

yoleaux | 12 Aug 2017 22:45Z <raschipi> masak: In your 007 macro experiments, is it possible to get the parse tree macros get like one would use Perl6::Parse for (in Perl6 instead of 007)? I mean, since it has to be able to hand parse trees to macros, is there an interface that makes it possible to get the same when parsing a string? | ||
raschipi | masak: my question was already answered, thanks. | ||
masak | raschipi: what was the answer? :) | ||
raschipi | That it's already possible to get it trough nqp. | 19:26 | |
masak | ah, nice | ||
though note that that would be NQP nodes, not Qtrees | |||
raschipi | Right. And do you have plans to make the later available? | ||
masak | raschipi: I think there's a 007 issue (still open) about the ability to go from string to Qtree. any such mechanism would be unhygienic, but it might still be useful sometimes. | 19:27 | |
in many cases you're better off combining quasis and synthetic nodes in some way | |||

brimonk | Is there a reason that references don't really exist in perl6? | 22:21 | |
Maybe they do, and I'm still figuring the language out. | |||
But they don't seem to exist. | 22:22 | ||
nadim | almosr everything is a refrence, so you don't need "reference" that's how things are | ||
brimonk | nadim: The syntax has just gotten easier to use then? | 22:23 | |

nadim | lizmat Any idea why requireing a module generates a "No such symbole" error? the trace nopaste.linux-dev.org/?1160729 | 22:33 | |
lizmat | nadim: sadly no: atm I'm trying to finish the P6W and then get some sleep :-) | 22:34 | |

I can try that. | |||
22:52
nhywyll left
|

nadim | it's pretty easy, clone the repo, follow the instruction, takes 3 mn to build | 22:52 | |
El_Che | Can CompUnit::Repository give me more than the name of a loaded module and optionaly a version if specified? I am playing with niner.name/talks/A%20look%20behind%...cker.html, and so far as I can see with the precomp thing, the best I can do to do a portable package of the loaded modules is to ship the precomp | 22:53 | |
directory with the module source somewhere if the user got a new rakudo version? | |||
brimonk | nadim: I've done it before, just making sure that I understood is all. | ||
The parse test is what takes the longest. | |||
nadim | doesn't matter what takes the longest, you have to do it anyway | 22:54 | |

Wait, | 22:56 | ||
El_Che | I see the travis build for perl6 uses rakudobrew and takes ages to run? Is there interest in using my linux packages so the images run way faster? Or is the choice for rakudobrew by design? | ||

El_Che | raschipi: using debs for rakudo the base setup would takes us from dozens of minutes to seconds | 23:05 | |
