dalek c/signature-test-option: fbe8525 | Altai-man++ | / (18 files):
This commit adds new pod config option: 'signature', and adapts current type documentation to it's usage instead of brackets addition.
AlexDaniel tbrowder: I see there's “Perl_6” on the experimental page (with underscore) 00:14
tbrowder: I'm not sure why, but my guess is that you probably mistaken in to   which is displayed as a colored underscore in emacs 00:15
it*
tbrowder:   being non-breaking space
sena_kun tbrowder, if you're using emacs, you can easily add non-breaking spaces with "C-x 8 space". Just number "8" and then normal space will do the trick. 00:16
AlexDaniel sena_kun: ｢C-x 8｣, right! I should probably use it more 00:18
tbrowder You both are correct. Can one of you correct that, please?
AlexDaniel sure

sena_kun AlexDaniel, I wonder how people work without emacs. Vim, probably. 00:19

Change Perl_6 to Perl 6

Sometimes it's not too hard to confuse non-breaking space with an underscore in emacs, as both are displayed as an underscore (one being different color).		 00:20
AlexDaniel sena_kun: I'm not sure if I'm with you on this. The thing is, I have solved so many problems that vim/emacs are trying to solve, but I did it on completely different levels (keyboard, layout, OS), so in my view if you do all that, then you don't really need emacs or vim. 00:23
00:23 canopus left
AlexDaniel for example, I don't need ｢C-x 8 space｣ because I can type it 00:23
sena_kun AlexDaniel, it can be. Anyway, not again this emacs/vim/anything flame. 00:24
AlexDaniel it is not a flame, it is just a different point of view :)
my point is that you can like your editor as much as you want, but you should always be open to other solutions to common problems. 00:26
Xliff I'm getting this error "Cannot unbox a type object" when attempting to pass a type object to a nativecall sub. 00:27
Isn't that allowed?
sena_kun AlexDaniel, more importangly, can you help me, please, with github.com/perl6/doc/pull/814? I'm worring about the CONTRIBUTING.md changes.
Xliff Rebuilding rakudo... just in case. 00:30
AlexDaniel sena_kun: I don't think that I am more native, but perhaps it would be better if it specified what kind of “body” it is talking about. Or maybe “don't do this” example can help? 00:31
sena_kun: but it is not that important really, people are more likely to look at other parts of the documentation to see what they should be doing

TimToady is not a bug 02:25
awwaiid What's the concept? 02:26
(or link to doc works too of course)
TimToady we need a literal notation for rats and complex, and <> is it
awwaiid how about the space vs no-space differene? 02:27
AlexDaniel m: say <42e2i>.perl
TimToady we don't need an extra literal notation for ints or nums, so we don't bother to treat <> special

AlexDaniel m: say < 42e2i >.perl

TimToady m: say <42e2+3i>.perl
camelia rakudo-moar 589061: OUTPUT«<4200+3i>␤»
awwaiid Right -- so 1/2 is an operation that results in a Rat, whereas <1/2> is a Rat literal.
(compiler optimization excepted) 02:28
TimToady yes, and while you can get away with (1/2), it only works by constant folding
awwaiid cool
TimToady and bare 1/2 is a problem if you have a surrounding operator that is tighter than /
02:28 noganex joined
TimToady so we just stole <> for those literals, but only when there's no space 02:29
sure, it's a little inconsistent, but there are reasons

TimToady generally, you wouldn't write that 02:30
it's just a degenerate case of qw

TimToady anyway, it's working as designed, even if you think the designer is an idiot :) 02:31
awwaiid not at all -- just want to understand. In this case :)
02:31 noganex_ left
awwaiid (kidding. TimToady++ # awesomesauce) 02:32
AlexDaniel TimToady: it kinda makes sense. “kinda” because it is very confusing at first and now I will be thinking “wait, what am I going to get here?” whenever I use <>, as there's no simple rule.
TimToady you think <> is inconsistent here, try inside regex :) 02:33
awwaiid so the rule is <> bumping right up against a slashy fraction is a Rat. What's with the RatStr?
best of both worlds I guess
TimToady allomorphism is for when someone is forced to use a textual representation, and needs a bit of dwimmery
awwaiid interesting 02:34
TimToady when someone is asked for a number at a prompt, you'd like to be able to treat it like a number
likewise, your program is forced to be a textual representation
BenGoldberg m: num $x = 0; ++$x; say $x;
camelia rakudo-moar 589061: OUTPUT«5===SORRY!5=== Error while compiling <tmp>␤Two terms in a row␤at <tmp>:1␤------> 3num7⏏5 $x = 0; ++$x; say $x;␤ expecting any of:␤ infix␤ infix stopper␤ statement end␤ statement modifier␤ st…»

yoleaux AlexDaniel: I'll pass your message to gfldex.
BenGoldberg wonders what would break if ++ on a num increased by the smallest amount which results a value greater that the initial num. 02:37
geekosaur everyone expecting $x = 0.5; $x++; to do what it does *everywhere* 02:40
also, I defy you to provide a simple, comprehensible explanation of the resulting behavior on floating point numbers (remember that said increase will scale depending on the magnitude of the original value) 02:42

camelia rakudo-moar 589061: OUTPUT«True␤»
geekosaur yes, but that's at least consistent with floating point everywhere else
BenGoldberg How about at least provide .smallest-greater and .largest-smaller methods? 02:44
TimToady and what would you do with it? 02:45
BenGoldberg TBH, I'm not sure ;)
TimToady adding 1 tends to have more real-world application, I suspect

TimToady Rats are really only useful when doing addition/subtraction with limited denominators
which is a lot of calculation, but not typically when you're multiplying by pi
geekosaur also iirc at one point the Rat implementation of pi was a hairier Rat, but that just made all Rat computations using it painful 03:07
(hairier but more precise)
although the counterargument there is that if you're doing Rat math involving pi, you're already doing it wrong >.> 03:09
or else need something more specific to whatever non-floating approximation you are using anyway
BenGoldberg thinks he's got an idea...
Would a method pi(Rat:U, $precision) make sense? 03:10

smls TimToady: Your grammar-based solution to rosettacode.org/wiki/Amb#Perl_6 doesn't work anymore in the latest Rakudo... :( 07:54
It simply *stops* after reaching the end of the first branch, and doesn't backtrack, so it prints no solution. 07:56
Strangely enough, it works if the <{...}> regex EVAL interpolations are replaced with the regex code they produce.
Did something change about the <{...}> feature that would prevent backtracking over it?
Here's the code with some cleanup and debug statements added, to show the problem: gist.github.com/smls/407f65d275810...2148f2312a 08:00

dalek c: eb847e3 | (Jan-Olof Hendig)++ | doc/Type/List.pod6:
Added docs for List.antipairs
 10:43
smls Why is .antipairs needed if it does the same thing as .pairs.invert ? 10:44
timotimo hoh, it is? 10:47
10:47 andrzejku left, wamba left
timotimo m: { :1a, :2b, :3c, :4d }.antipairs.perl.say 10:47
camelia rakudo-moar 589061: OUTPUT«(1 => "a", 4 => "d", 3 => "c", 2 => "b").Seq␤»

camelia rakudo-moar 589061: OUTPUT«(1 => "a", 4 => "d", 3 => "c", 2 => "b").Seq␤»
dogbert17 timotimo: there's something fishy here, there is an implementation of 'invert' in List.pm, but it soes not seem to work 10:49
m: say (1,2,3).invert # ?? 10:50
camelia rakudo-moar 589061: OUTPUT«Method 'value' not found for invocant of class 'Int'␤ in block <unit> at <tmp> line 1␤␤»
timotimo um, that's quite weird
to have .invert on list do what antipairs does on a hash, but only if the list is a list of pairs
10:50 wamba joined
dogbert17 the code is a one-liner: self.map({ nqp::decont(.value) »=>» .key }).flat 10:50
timotimo right 10:51
i find that ... weird
also, why would it have »=>» there? unless there's more than one key per thing? 10:52
dogbert17 timotimo: it could be I guess, in other places invert drills down into lists
docs.perl6.org/type/Map#method_invert 10:53
I wonder if there is a :kv missing from List.invert 10:54
smls ah.
timotimo could be, yeah
dogbert17 where's lizmat when we need her :) 10:56
lizmat I'm here
.oO( you rang? )
I'm not sure why we have List.invert either.... I don't think I touched it in any opt work
dogbert17 can you backlog ~15 lines please :) 10:57
lizmat Hash.invert is *not* the same as Hash.antipairs

RabidGravy (but schwern made me do that one)
dogbert17 have you managed to stop Brexit ?
RabidGravy working on it 10:59
lizmat dogbert17: all I can say is that TimToady added/changed it early 2015
RabidGravy HACKERS FOR EUROPE!
timotimo HACK THE CONTINENT!!
dogbert17 lizmat: maybe we'll have to wait for his comments on the matter then 11:00
lizmat is checking further
11:01 rindolf joined
dogbert17 RabidGravy: have you tried your musicstreaming stuff lately. perhaps it works better/faster now thanks to all recent opts? 11:01
lizmat feels to me that .invert on a List *is* the same as antipairs
dogbert17 lizmat: in which case it would be redundant 11:02
11:02 pierre_ joined
lizmat well, I guess we want to keep supplying it so you can call .invert on anyhing 11:03
dogbert17 lizmat: in which case we have a bug :)
lizmat yeah

lizmat hopes Apple will come out with a 32core MBP soon 11:08
11:09 itaipu joined
dogbert17 guess Apple will have something new besides iPhones in September 11:12
lizmat hmmmm I borked 2 spectests 11:14
dogbert17 uh oh 11:15
smls Having List.invert invert the pairs of a list of pairs, is not that different than other instances where Perl 6 treats lists of pairs specially... 11:16
lizmat apparently you can only List.invert if the List contains pairs
dogbert17: so In guess the right course of action would be to rakudobug it as a @LARRY bug 11:18
11:19 stmuk joined
dogbert17 lizmat: so the bug is that it only handles list of pairs? 11:20
lizmat well, I guess the bug is that the error is really LTA if the list does not consist of pairs *OR* it should call .pairs on itself first before inverting 11:21
(aka, be the same as .antipairs)
11:21 stmuk_ left
dogbert17 so a mail to [email@hidden.address] with [BUG] and @LARRY then? 11:22
in the subject that is 11:23
11:24 stmuk_ joined 11:26 stmuk left
lizmat dogbert17: yup 11:33
dogbert17: (sorry, was distracted)
dogbert17 lizmat: rt.perl.org/Public/Bug/Display.html?id=128860 11:36
lizmat dogbert17++ 11:37
dogbert17 hooray, thx for the help 11:38
btw, what's the fastest way in Perl 6 to split a string into a list of single characters, comb? 11:39
lizmat yup, .comb 11:40
dogbert17 lizmat: thx, I was working on a Project Euler problem and got the impression that comb is rather slow. Is it a target for opts in the future? 11:41
lizmat I was just looking at it again
dogbert17 I'm specifically referring to the default case. i.e. "string".comb 11:42
MasterDuke bench: releases .comb for ^100000 11:44
11:44 pierre_ left
benchable MasterDuke: gist.github.com/ee0173e2863fb8b944...332eaefd62 11:45
dogbert17 MasterDuke: cool 11:46
MasterDuke looks like it did get twice as fast between 2016.06 and 2016.07
dogbert17 MasterDuke: indeed
lizmat yeah, but that was not because of changes to .comb itself 11:47
dogbert17 I was working on projecteuler.net/problem=112 in case you're interested
MasterDuke github.com/rakudo/rakudo/commit/efbfdaa 11:48
that's where benchable found the difference
dogbert17 those bots are nifty 11:49
MasterDuke projecteuler.net/problem=60 is what got me started committing to Rakudo 11:51
been stuck/working on that one for a long time now
dogbert17 That one I haven't solved :( 11:52
MasterDuke it's why i wrote github.com/MasterDuke17/List-Combinations 11:53
because the core combinations() was too slow 11:54
dogbert17 nice, I actually managed to solve 112, and comb definitely played a part, but the code took like 6 minutes to run on my machine 11:56
replacing comb with some % and div trickery reduced the time to approx one minute 11:57
MasterDuke nice. my Perl 5 solution takes 6 seconds 11:58
using a 'split //' 11:59
dogbert17 yeah, there's still some work to be done although some other problems which I solved earlier in the year have become much faster thx mainly to lizmat++ and jnthn++

RabidGravy I was thinking about that metaphone thing and unicode, seeing as metaphone (and soundex) are pretty useless for anything other than ascii words 13:43
is there a reliable way of knowing for a given character whether it is based on a latin character (in the rakudo implementation)? 13:45
13:47 lucar joined
lucar Hi there 13:47
how does the perl6 repl compare with Common Lisp? 13:48
does it support interactive coding ?
DrForr As far as I know, yeah. It lets you type in code, read it, eval's it and prints it, just like CL. 13:49
lucar great
arnsholt The Perl 6 REPL isn't as functional as you'd get from something like SBCL
