OK. Due to metachars, there is no way to get this any cleaner, right? 00:19

timotimo of course it can be cleaner
AlexDaniel ‘’
timotimo you can use quotes
Xliff Even with the Alternative delimeter on the substitution operator.

timotimo no, i don't think it would work
inside quotes, backslash sequences mean what they mean outside regexes 00:21

ZoffixWin I get my mistake now.
Xliff ZoffixWin, ahh! Thanks! Bookmarking now.
timotimo AlexDaniel: yes, you very much can
Xliff And I'm not using rexexp to parse HTML. I am using it to REMOVE XML. 00:24
timotimo you can only remove XML properly if you parse it properly :P
ZoffixWin :P
timotimo otherwise you'll easily get confused by smileys that include > and <
ZoffixWin Xliff, sure, that's why I merely mentioned and not shouted at you ^_^
Xliff If the problem-set requires that the program needs to grok XML. 00:25
If the XML is just the same as any other text, it isn't parsing.
There is a difference, even if it's splitting hairs.
And I'm assured that I do not have to worry about smileys.
AlexDaniel .tell jnthn hey. Perhaps leave this in a terminal for several minutes or something: ｢while :; do perl6 -e 'await (start { print ‘x’; sleep 1; } for ^100); say ‘’;'; done｣ 00:27
yoleaux AlexDaniel: I'll pass your message to jnthn.
AlexDaniel .tell jnthn also, there's one thing that I've noticed. Maybe that will tell you something, who knows. See this screenshot: files.progarm.org/2016-04-08-03282..._scrot.png . So, it looks like there's a maximum number of threads or something, so these ‘x’-es are appearing in batches. It crashes only during the second batch, hmmm… 00:30
yoleaux AlexDaniel: I'll pass your message to jnthn.
AlexDaniel .tell jnthn that is, the exception always appears after exactly 32 ‘x’ characters
yoleaux AlexDaniel: I'll pass your message to jnthn.

Xliff Heh
ZoffixWin No idea why that code shows that error :S
Xliff Yeah. Figured it out. 00:41
"$newIndexF.defined" was what was throwing the error. Replaced with "$newIndex === Nil" fixed it. 00:42
Still, I would expect a better error to be emitted for that.
ZoffixWin, another datapoint. If I do "if (!$indexF.defined) { ... }" it works as opposed to "{...} if !$indexF.defined" 00:55

Nope. Blows up every time I try that or a variant.

36k file.
for $contents ~~ m:g/ '<' (.+?) '>' (.+?) '</' $0 '>'/ -> $t {
... } <--- Seems to be an endless loop.
AlexDaniel Xliff: maybe you'll finally stop trying to parse html yourself? :D 05:17
Xliff AlexDaniel: I've tried using Mojo::DOM and it didn't work.
AlexDaniel Xliff: good. Just use Gumbo
Xliff Gumbo might not work. Mainly because I might not have a good enough understanding of Inline::Perl5. 05:18
Gumbo is perl6 native though, right?
But that's really not the issue.
The above for loop never completes and it should.
Dropping the length of $contents from 36k to 500, the loop completes immediately. 05:19
AlexDaniel Xliff: Gumbo is a Perl 6 module
Xliff AlexDaniel, good to know. That's next.
Dropping the length of $contents to 5k... the loop still never completes.
Could be the regexp? But why work at 500, and not 5k? 05:20
AlexDaniel Xliff: I don't think that it is a bug. Most likely it starts backtracking and it just takes time…
Xliff OK. Can I turn off backtracking?
Xliff looks at docs.
AlexDaniel Xliff: perhaps you can make its life easier by doing something like '<' (<-['>']>+) '>' 05:21
skids Some of that works. Like use an empty closure e.g. "{ 1; }" as a sequence point
Xliff m/ '<' (.+:?) '>' (.+:?) '</' $0 '>'/ <-- ? 05:22
I'm getting this at the end of execution:
"Cannot convert string to number: base-10 number must begin with valid digits or '.' in '...'"
Where "..." is the rest of $contents 05:23
Definitely an improvement --> m:g/ '<' (<-[>]>+) '>' (.+?) '</' $0 '>'/ 05:25

The reason I am using the p5 sub is because when I try to use $m.find() in a P6 context, I don't get anything back, and I should. 07:38
moritz is that because of list vs. scalar context?
Xliff Even using $m.children() returns nothing, and I know that there are <p> tags in $content.
moritz: An earlier version did "my @tags = $m.children('p')" with no results. 07:39
Timbus the error indicates that, somehow, $m is undefined. at least from perl5's point of view 07:40
Mojo::DOM source confirms that its trying to do $_[0]->_css 07:41
Xliff Timbus: I can confirm that $m is "Inline::Perl5::Perl5Object.new(ptr => NativeCall::Types::Pointer.new(211119144), perl5 => Inline::Perl5.new)" before the $p5.call()
Timbus which is what initially failed in find()
why not print out what $m is from your perl5 sub
Xliff OK
07:43 zakharyas joined
Timbus at a guess its like.. a blessed undef? because the -> part works.. 07:43

the "Inline::Perl5::Perl5Object.new(ptr => NativeCall::Types::Pointer.new(216816896), perl5 => Inline::Perl5.new)" says that $m is not undefined.
At least not according to P6 07:46
Timbus i know that part, but yeah, something happens to it when you pass it back
garbage collection?
Xliff OK. Just as long as I am not making an obvious mistake. 07:47
.....am I?
Now H
*ggrrrr*
Now GC would be non-obvious. I wouldn't expect GC to hit the way the scoping should work.
Depends on how Inline::Perl5 works. 07:48
Timbus I mean the perl 5 GC. like you even get some crazy double-free thing going on after it crashes
and youre clearly calling methods on undefs, which should definitely be defined
Xliff Timbus, JINX! --> *punch*]
Timbus :/ 07:49
Xliff LOL
Seriously. I appreciate the help.
Timbus you might wanna uhh.. make your Mojo::DOM in the perl5 sub, or not use .call ?
Xliff You mean use "Mojo::DOM" in the p5 scope?
Timbus I mean, that's not really what you should do, but if you have to... 07:50
Xliff Can't NOT use call, since I tried it that way at first and got Nil as a result.
Timbus Nil seems saner than your other attempts, tbh 07:51
Xliff "$m.children('p')" should have returned a list of Mojo::Collection, but did not. It returned undef. 07:52
Or Nil, if you want to be technical. But it should not have returned that.
I know what the XML/HTML looks like. I did not get the results that I expected. 07:53

El_Che sdo: you're maybe compiling the jvm backend? you can specify to only compile moarvm 08:31

00:30Z <AlexDaniel> jnthn: also, there's one thing that I've noticed. Maybe that will tell you something, who knows. See this screenshot: files.progarm.org/2016-04-08-03282..._scrot.png . So, it looks like there's a maximum number of threads or something, so these ‘x’-es are appearing in batches. It crashes only during the second batch, hmmm…

Ulti Swift is like the corporate sister to Perl 6 in my mind especially around some of its bigger opinion pieces like unicode support 08:35

jnthn Ulti: Oh...for [+] 1..100000 ?

that still counts towards my comment to the reddit around zoffix post
jnthn github.com/rakudo/rakudo/blob/nom/...ge.pm#L653 08:38
hah, reddit...bet that's a hotbed of positivity :P

jnthn Uh, yeah... :)

MadcapJake truthfully, I probably wouldn't have been able to use it, just got curious if it was possible 14:31

smls I don't think it should 15:58
gregf_ well, then why lock a resource ;)
smls you *don't* lock anything 15:59
you just initialize a lock, but never call .protect
gregf_ smls: granted, in the code above.. you can stick in a $lock.protect { # access_chared_resources} *cries*

smls ^^ I get varying results from 8 to 10 for that 16:03
skink Probably a stupid question: if I'm supplying random numbers, should they be Big Endian or Little?
[Coke] skink: huh? 16:04
skink I'm taking a Buf[uint8] and deriving an Int from it
[Coke] ah, I missed some backscroll, I guess.
skink I was .unpack("L") vs ("N") 16:05
considering*
Well, rather, I was using "L" and then just found a way of doing it that's an order of magnitude faster but it's big endian 16:06
skids If the random number is over the entire binary field and equally distributed, and nothing sees the original buffer, it should not matter. 16:08
skink skids, That last optimization you pasted last night brought me from ~115 UUID/s to ~725 16:09
16:09 sue joined
skids glad to help. I'm sure there must be more to gain. 16:09
RabidGravy if you have four bytes and want to turn then into an Int it's just "my $int = ($buf[0] +< 0x18 ) + ($buf[1] +< 0x10) + ($buf[2] +< 0x08) + $buf[3] 16:10
skink Now I'm optimizing the Int generation and allowing for arbitrary-sized results rather than just 32bit ones.
RabidGravy, That's basically what I'm doing now. 16:11
RabidGravy cool
skink my Int $count = 0;
($count +<= 8) += $_ for crypt_random_buf($length).values;

ufobat okay got it so far 19:03
ZoffixWin Sorry, that wasn't an answer from me, I just wanted to see what .signature would give from a block.

19:03 labster joined, labster left, labster joined
ufobat so a Block does not have a own @_, and return does not leave a block but the outer routine 19:04

ChristopherBotto It didn't, but I thought it should.

perlpilot ChristopherBotto: Though, I note that P5 doesn't seem to run END blocks after a SIGINT or SIGTERM 21:05
sortiz skink, Is a good idea to include it in P6-UUID, try a PR. 21:07
21:08 sufrostico joined
lizmat indeed, the END block does not appear to be run 21:14
ChristopherBotto: this is a workaround:
signal(SIGTERM).act: { exit 1 }; Nil while 1; END say "this is the end, my friend"
m: signal(SIGTERM).act: { exit 1 }; Nil while 1; END say "this is the end, my friend" 21:15
perlpilot would be surpised if that worked in camelia
jnthn I'd expect you'd need to install a handler that calls exit

jnthn Oh, exactly as lizmat showed :)

jnthn <-- nearly too tired to read :) 21:16
lizmat jnthn: would you consider that a work around or not ?
jnthn lizmat: I don't mind it being that way, I think 21:17
lizmat neither :-) 21:18
jnthn Installing that handler by default at present would also be rather costly, though that reason won't be with us forever I hope :)
perlpilot ChristopherBotto: what did you want to rely on running in the END phaser anyway? 21:19

grondilu doesn't postcircumfix:<[]> point to .list with no arguments?
grondilu suddenly vaguely remembers it doesn't.
ChristopherBotto skink: I meant, why do you check $one OR $two? Shouldn't they both hold the same number of bytes? 21:54

lizmat ChristopherBotto: you can actually do: signal(SIGTERM,SIGINT).act: { exit 1 }
skink ChristopherBotto, Yeah that should be && 21:59
lizmat I have no idea what could be causing the spurious error... perhaps running it with --ll-exception might help ?
skink sortiz, That's in a cleanup commit I forgot to push
sortiz skink, You can pass a pre-allocated Buf to NC functions and avoid the CArray, for example: sub SystemFunction036(Buf, uint64) is 'native'; my $bytes=Buf.allocate($len); SystemFunction036($bytes,$len). 22:03

skink sortiz, Neat, I'll try it out 22:13
sortiz, Which would also render the carray-to-buf unneeded 22:17
sortiz skink, yep. For native types, using preallocated bufs is better that CArray. Think in Buf[foo].allocate as Perl6's calloc. 22:20
skink So Buf[uint8].allocate? 22:21
sortiz Buf by default is Buf[uint8] :-)

22:27 spintronic left
sortiz Yep, in general native types are faster, so when possible use uint64 over UInt64. 22:28
22:28 firstdayonthejob left, pmurias left 22:29 sufrostico left
skink I figured. 22:29
sortiz Moreover UInt and variants are subtypes so even there are more expensive. 22:30
skink I was wondering what the performance impact of those was. Comparison for every value? 22:31
22:32 sufrostico joined
sortiz See ZoffixWin++ latest blog. 22:33
22:33 ChristopherBotto left
skink I read that earlier. It has native types but not subsets. 22:34
sortiz, Because left-shift adding was faster than .unpack() I had decided to return Int for random(_uniform). Should I change that behavior? 22:35
22:35 kalio left
sortiz Ahh, Are you talking about the subtypes, yes, every assignation should be checked. 22:35
22:36 sufrostico left
sortiz skink, dunno for that particular case, so you should benchmark that. 22:36
sortiz need a coffee, bbl 22:38
skink Well that spouts an error trying to <+= and += the uint64, and returning and taking uint64 makes a whopping 1% performance difference 22:42
22:43 skids joined, Sgeo joined, RabidGravy left
sortiz The error can be a bug, I've seen other. And %1 not worth it. 22:47
skink I'm defaulting to 32bit to mimic arc4random()'s native behavior, but I like the idea of being able to return 8/16/32/64/any from a single short function. 22:48
Taking a uint64 is actually optimal though, since that's actually the number of bytes. 22:50
sortiz, Think the module's ready to add to the list? 22:56
sortiz Sure! 22:57

Timbus how involved is it? i have a VPS using 12.04 23:06
23:10 kid51 joined
sortiz Timbus, not code related, but mysql related. Seems (via travis-ci) that mysql shipped with Precise don't like DATETIME with precision as a column definition. 23:11
Timbus hmmm let me see if it has mysql. i think i opted for pgsql for my wordpress
nope it has mysql. what you need me to copy/paste for ya 23:12
hopefully SQL?
sortiz can you successfully create a table like: 'CREATE TABLE test( date DATETIME(6))' ? 23:14
Timbus ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(6))' at line 1 23:21
sorry, was semi-afk
hope that helps?

teatime as far as I can see.. 23:37
23:37 Khisanth left
teatime the return for upper_bound < 2 is also weird.. wouldn't 1 be a valid upper bound? 23:39
skink It's exclusive, so if you set upper_bound to 1 it can only possibly return 0 23:40
So it just skips the math
teatime oh ok
skink And an upper_bound of 0 would just break it
23:41 AlexDaniel left
teatime yeah it does explicitly say [0, upper_bound) doesn't it 23:41

skink: if you say unary - on a uint32 what type does it get upgraded to? 23:46
a longer signed int type? I don't know the answer, but if it's something unexpected maybe it's just very 'clever' code that does something useful. 23:47

yeah, for 2's complement you have to add 1
23:58 wamba joined
skink So if I wanna use an Int as input I'll have to emulate that behavior in a different way. 23:58
teatime I was actually trying to see if www.codingstandard.com/rule/5-3-1-d...gned-type/ were actually equivalent operations. 23:59
timotimo yeah, i think our UInt is just Int with a refinement that complains if it's a negative value
skink Well, I'm dumb.
/* 2**32 % x == (2**32 - x) % x */
It's right there.
