[Tux] Goot * folk, has something changed in Numification? I see CSV tests fail where I did not change anything 11:38
lizmat [Tux] could be me, do you have a golf ? 11:44
[Tux] m: dd +"15".unival.Int 11:46
camelia 1
lizmat .ask samcv how hard would it be to create a "give me a random key of a hash" nqp op that would be significantly faster than the current Map.roll ?
yoleaux lizmat: I'll pass your message to samcv.
lizmat [Tux]: do you that's wrong ? 11:47
*think
[Tux] no, but I now have doubts about the line before it:
method Numeric {
$!text.defined
?? $!text.starts-with(0..9) ?? +$!text
!! $!text.unival.Int
!! Num;
}
m: my Str $t = "15"; $t.starts-with(0..9) and say "YES"; 11:49
camelia ( no output )
[Tux] that used to say YES
AlexDaniel lizmat: please see github.com/rakudo/rakudo/wiki/Ticket-updates 11:52
lizmat: there are two reports for the last two week (current week will be ready tomorrow), one more for the month of Dec and another one for the whole 2018 year
s
c: 2018.12 my Str $t = "15"; $t.starts-with(0..9) and say "YES"; 11:54

committable6 AlexDaniel, ¦releases (36 commits): «» 11:55
AlexDaniel [Tux]: no, it never said YES
[Tux] then /me wonders why those tests ever PASSed
AlexDaniel do you have the full test as a gist? we can bisect 11:56
lizmat weekly: github.com/rakudo/rakudo/wiki/Ticket-updates
notable6 lizmat, Noted!
lizmat AlexDaniel++
[Tux] it is t/30_field.t fro Text::CSV
m 11:57
AlexDaniel oh so Blin should be able to figure it out, right?
AlexDaniel runs `PERL6LIB=lib ./bin/blin.p6 --old=2018.10 Text::CSV` 11:58
[Tux] tux.nl/Files/x.pl ← minimized test case 11:59
AlexDaniel c: releases gist.github.com/AlexDaniel/92f6f26...a70b71c252
committable6 AlexDaniel, gist.github.com/411652a91700e189da...61b489b1b0 12:00
AlexDaniel [Tux]: see ↑
if there was a change, then the test case is too minimized
[Tux] apologizes - looks like a local change that isn't pushed and that could never have worked: 12:02
- ?? $!text ~~ m{^ <[0..9]> } ?? +$!text
+ ?? $!text.starts-with(0..9) ?? +$!text
but should it? :) 12:03
AlexDaniel [Tux]: Blin refused to bisect it because tests passed: gist.github.com/AlexDaniel/45bb958...ffe8f550ea
oh, ok, I see :)
Blin++ committable6++ :) 12:04
[Tux]: see also github.com/rakudo/rakudo/issues/2268 12:05
TL;DR everybody wants to add more candidates to basic string matching functions because performance, but we should be making regex matches faster instead 12:08
and if that's not possible, add just one more function that doesn't create a Match object
IMO 12:09
[Tux] I think I agree. My change was however not directly geared towards not using regexes, as to DWIM'ary 12:11
AlexDaniel sorry, no, it doesn't look like a good idea 12:14
it may look cute for 0..9, but what about other kinds of ranges? 12:15
like 0..999? -999..999? Should it all work?
what about string ranges?
False..True? What does that match? 12:16
[Tux] all of those examples would at least *read* easier than a regex
AlexDaniel even if I can read them easily, I still have no idea what they'd do :) 12:17
[Tux] I'd restrict the list to Cool, but I was just fantasising
AlexDaniel and what does that mean? 12:18
[Tux] 0..999: the string starts with 1 to three digits (probably a lot less efficient than using a regex)
-999..999: The string starts with an optional minus folowed by 1 to 3 digits. Again a lot slower than a regex 12:19
but yes, a gray zone
AlexDaniel so what if it starts with a plus?
[Tux] it doesn't match
AlexDaniel why? 12:20
see…
[Tux] because the range has no plus
AlexDaniel how do you create a range with a plus?
[Tux] with map :P
AlexDaniel ok, fine, I'll take that
now, unicode minus and hyphen-minus at the same time, right? 12:21
[Tux] nope
AlexDaniel I mean… it's probably more explicit to write your own regex… 12:22
[Tux] 00002d 0002d7 002212 002796 00ff0d
yes, a regex is much clearer in most cases (when entering the gray zone)
AlexDaniel it's not exactly a gray zone 12:23
it's something we will have to implement and test
[Tux] but just like with split/haystack, $string.starts-with(@list), where @list is a list of Cool, should be DWIM
AlexDaniel github.com/perl6/doc/issues/992 12:25
kinda reverse though, hmm
[Tux] is is just a translation to something like @list.first($string.starts-with(*)}
given the correct parens and races and whatever 12:26
AlexDaniel m: say ‘f o o’.starts-with(<f o>)
camelia True
AlexDaniel m: say ‘fo o’.starts-with(<f o>)
camelia False
AlexDaniel right, still github.com/perl6/doc/issues/992 I'd say
[Tux] indeed 992 in reverse
m: ("A" .. "M").first: "Zoe".starts-with(*); 12:41
camelia Cannot resolve caller starts-with(Str:D: Whatever:D); none of these signatures match:
(Str:D: Cool:D $needle, *%_ --> Bool)
(Str:D: Str:D $needle, *%_ --> Bool)
in block <unit> at <tmp> line 1
[Tux] should that be valid? I just read the docs on "first", but I don't see why that barfs

lizmat [Tux]: it barfs on starts-with 12:43
m: "a".starts-with(*)
camelia Cannot resolve caller starts-with(Str:D: Whatever:D); none of these signatures match:
(Str:D: Cool:D $needle, *%_ --> Bool)
(Str:D: Str:D $needle, *%_ --> Bool)
in block <unit> at <tmp> line 1
[Tux] I see, but *why* 12:47
* comes from first
so it is "A" .. "M" until the part right of: is true 12:48
[Tux] must go now. Lunch and then new-years visit :( 12:49

samcv lizmat, well. i mean you could do it faster than now 15:51
yoleaux 11:46Z <lizmat> samcv: how hard would it be to create a "give me a random key of a hash" nqp op that would be significantly faster than the current Map.roll ?
samcv i mean i'd probably choose a random slot and then choose a random key in the chain inside that slot
so i guess the answer is yet :) 15:52
