tadzik good morning #perl6 04:21
sorear hello tadzik
tadzik sorear: what's so bad about IRC?
sorear where do I begin? 04:22
tadzik I wonder
sorear enforced tree topology makes redundant connections impossible
no way for clients to transparently resume after a connection drop
510-character limit by truncation brain damage
lack of character encoding awareness 04:23
inadequate handling of presense data
no remote echo
"standard" that NO server follows anymore 04:24
ad-hoc extensions with no discovery protocol
basically, the protocol is set up at every level to make it impossible to write a better client than irssi 04:25
tadzik I see your point
sorear I learned most of this when I got fed up with irssi and tried to do exactly that
Eevee time for a new protocol
tadzik or for wider adoption 04:26

&foo adds to %*MYSTERY
sorear yeah, it's basically done except for the "defined but not used" warnings, which keep bouncing between oversensitive and undersensitive 05:37
TimToady I gave niecza more visibility on the rosettacode.org/wiki/Category:Perl_6 page today
tadzik examtime & 05:39
TimToady have the appropriate amount of fun 05:40
sorear it' 05:42
it's not regressed on spectests at this point (though I haven't reviewed warnings yet), also can compile itself again
05:46 wamba joined
sorear I'm thinking of changing source position in backtraces to a range of positions 05:48
if we have A(B), then there are 3 possible points for an exception - in eval(A), in eval(B), or in apply() 05:50
05:50 jdv79 left
sorear the other trick is that sometimes niecza doesn't exactly know when an exception came in, due to a bit of CLR brain damage 05:50
so sometimes niecza might know "either in eval(A) or eval(B), but definitely not in apply" 05:51
I wonder how best to present that to the user
05:51 jdv79 joined

sorear then I decided to ask what it was one day...

sorear ok then
06:41 Woodi joined 06:42 birdwindupbird joined
TimToady a tighter based on a looser op is always looser than the looser based on the tigher op; such precedence levels never overlap, so tighter/looser are only tiebreakers if the original precedence would be ambig 06:43
06:43 Aridai joined
TimToady if if there is a between of the original precedence levels, it's between all the looser-tighters and all the tighter-loosers, as it were 06:44
sorear between exists?
or do you just mean like + relative to tighter(=) and looser(*) ? 06:45
TimToady it was speculated at least
tighters and loosers are only infinitesimally far away from their base prec
though you can always fit more in 06:46
if we have between, it has to interpolate though
interpolating between loosers and tighters looks to be fraught with peril, though :) 06:47

p6eval pugs: OUTPUT«24␤»
TimToady I don't think pugs does anything with tighter/looser
sorear doesn't look like it
so probably niecza will be the first implementation to do infinite precedence \o/
TimToady well, till you run out of memory :) 06:49
06:50 cooper left, cooper joined
TimToady similarly a tighter(looser(+)) is still looser than + 06:50
06:50 sanc joined
sorear I could make between work, using infinitesimal calculus, but it would be a pain to test and it would probably slow down EXPR 06:51
since it wouldn't be able to use lt/gt anymore
plus I'm not really sure "0.5 of the way between the arguments precedence" is really _useful_ 06:52
TimToady you'd just have to figure out some way to generate an intermediate string
06:52 cooper left
TimToady me either 06:52
06:52 cooper joined
TimToady so consider it conjectural 06:52
sorear if we wanted to go that far I'd rather see topological sorting stuff
where you give X > Y constraints, and then the system decides if operators are <, >, =, incomparable by the transitive closure 06:53
TimToady oh, I think we decided to replace 'is between' with 'is tighter is looser'
and let the two traits fight it out :)
sorear I think I proposed that system for Haskell' back when I was 10 or so...
hmm 06:54
TimToady in any case, don't need new syntax for it
sorear ah, Haskell' was 2010, not 2000
that's more consistent with my timeline... I didn't think I was playing with Haskell until after I was on Linux, which required post-13 06:55
06:55 natureboy joined 06:56 cooper left
TimToady useful topological prec likely requires you to name both upper and lower bounds, which is problematic from an extensibility point of view 06:58
06:58 kai__ joined
TimToady the between stuff more more useful for bootstrapping your initial levels, I suspect 06:59
sorear I was supposing just is Niecza::absprec<k= right> for that
TimToady so you can get the moral equivalen of the a..z levels without going all Church numerally 07:00
sorear between needs at least 2 prec levels to bootstrap
TimToady yes, but you can see how you could bootstrap between a..z with a split-the-difference thing
sorear and I'd rather have a system that allows users to see at a glance that is absprec<i= right> is related to constant $item_assignment_prec = 'i='; 07:01
TimToady yes, I prefer to hardwire the initial levels 07:02
it's an example of "Give them all the rope they want to be flexible, but then give them enough options that the don't want to extend it." :)
*they
that's easier with precedence levels than with operators, of course 07:03
but we'll probabl never add factorial as a built-in op simply because it's such an amusing operator to add :)
sorear "show me the use case" 07:04
factorial... well it's a great builtin operator in Maxima
but Perl 6 has no delusions of being a CAS
TimToady we've got plenty of delusions already, thank you... 07:05

moritz you have to check how often the grep block is executed
not how often the generating code block is executed
you see that it only goes up to 13 in the generating block
so you know that it stopped after it found the first match
colomon right, that's because !@a.grep translators to !?@a.grep 13:44

arnsholt moritz: Yeah, I didn't include parrot, that's true 14:27
moritz though parallelized parrot rebuild with ccache isn't slow either 14:28

icwiener Hi, small question: What kind of regexpes does the smart match operator expect? 16:22
PerlJam what kind? 16:24
icwiener: what do you mean? 16:25
icwiener PerlJam: Well, I use a regular expression that works fine with plain grep but Perl6 gives me a syntax error there. if $line ~~ /^\#.*20[01][0-9]\.$/ { 16:26
So I thought Perl6 might use a different style of regular expressions.
PerlJam oh!
perl 6 expects Perl 6 regex :)
16:27 dju_ left, mj41 joined
PerlJam icwiener: Perl 6 has refactored regex syntax somewhat so, for instance, character classes are now <[0..9]> instead of [0-9] 16:27
icwiener Hmm,, the ones I saw pretty much looked the same as the usual extended regexp I used to use in Perl 5.
Oh! 16:28
PerlJam but maybe you want to use \d instead ?
icwiener That explains a bit. :)
Is there something to read about the new syntax? 16:29
PerlJam icwiener: well, there's github.com/perlpilot/perl6-docs/bl...-intro.pod

I think this is a bug waiting to happen... what if $obj1 === $obj2, but the first call triggers a garbage collection which changes the object's address? 18:49

masak sorear: agreed. 19:03
sorear: I've been meaning to look at the diff and perhaps blog about it.
it will be a few days before I have that kind of time; probably sometime early next week. 19:04

colomon so, MAIN(Int $n) doesn't work? 19:20
PerlJam I think it's mainly because I have these ideas of things I want to work on for $work, but I have to put together a narrative for a proposal by tomorrow and that's more important but less fun.
masak moritz: today, researching Perl 5's pseudo-package SUPER, I realized that it actually does handle MRO and MI. I'm not advocating putting it back into Perl 6 (because nextsame et al are just fine), but I no longer see a conceptual problem with having it there. 19:21
moritz masak: but it is otherwise completely insane 19:24
masak right, exactly.
PerlJam heh
moritz ie it's not tied to an invocant, but to the current package
masak it just struck me that the "won't work with MI" objection wasn't very strong, since it does work with MI in Perl 5. 19:25
moritz but does it work *well* with MI in Perl 5?
masak I didn't say that. :)
19:25 bluescreen10 joined
colomon what I'm seeing (this is in master): MAIN(Int $n) doesn't work. MAIN($n) works, but then hides MAIN("test") (ie if the command-line argument is "test", MAIN($n) is called. Help? 19:25
masak I don't plan to use MI much in Perl 5. Perl 5 has Moose, and Moose has roles. 19:26
colomon: the former is well-known. the latter sounds weird and new.
colomon: are those really multis?
rakudo: sub MAIN("test") {}; sub MAIN($n) {} 19:27
p6eval rakudo 248244: OUTPUT«===SORRY!===␤Cannot re-declare sub &MAIN without declaring it multi at line 22, near ""␤»

masak ah.
masak didn't know that 19:29
is that filed?
colomon moritz++
moritz but it just iterates over the candidates, and invokes the first one it finds
erm, the first one it can bind to

Moukeddar_ Hi guys , hope you're all fine 19:31
masak Moukeddar_: hi Moukeddar_ of the abundant whitespace ;) 19:32
tadzik hello Moukeddar_
Moukeddar_ you noticed that ?
what's cooking in the labs? 19:33
masak well, jnthn++ is working on nom, sorear++ is hacking away on Niecza, and the rest of as are (to a first approximation) awestruck by their productivity. :) 19:34
moritz masak: btw I'm working on github.com/moritz/WebService-Libris right now

Moukeddar_ so you think you can code ? 19:39

Moukeddar_ you know the TV shows , Dance with the stars , America got talent , so you think you can dance etc...
masak ah. 19:41
Moukeddar_ please please , overlook the spaces:)
masak in this case, quotes would've helped more :P

Moukeddar_ yes, certainly 19:41
masak it's the ol' use-mention distinction. some of us are very into that one.

Moukeddar_ i can tell 19:42
masak Moukeddar is 185 cm tall, but "Moukeddar" is 8 characters wide :) 19:43

middle value is always the best

flussence I seem to have misplaced my clue today :)

masak I'm curious how the spec for uniq would read.
Moukeddar_ the one and the five?N
do you guys use mocking? 19:45
tadzik yes
masak oops, sorry. 9 characters wide. :)
Moukeddar_: I used it today at work.
Moukeddar_ pretty useful, but all the web is teaching you how to use existing libs , what if you wanted to make your own ? 19:46
masak Moukeddar_: I didn't use a lib. I just wrote the code I needed.
moritz Moukeddar_: www.youtube.com/watch?v=aAb7hSCtvGw
Moukeddar_ i as a try, i created a FakeRepository which implemented the IRepository , i guess that's the principle , right? 19:47
masak aye, sounds like a good start. 19:48
Moukeddar_ moritz, kisses and hugs to you
lue hello zebras o/
Moukeddar_ and the FakeRepository would return specific items/values i hard-coded
moritz Moukeddar_: that's a bit... over-enthusiastic
Moukeddar_ it's completely normal 19:49
moritz depends on the culture
Moukeddar_ i guess
masak lue: hello little panda 19:50
tadzik lue: o/ 19:51
masak yes, we don't have a kissbot ;)
Moukeddar_ you should have one
masak I'm not so sure...
we're pretty radical with the hugs already, compared to other channels. 19:52
tadzik i prefer hugs, especially when it comes to the male population
moritz same here
Moukeddar_ homophobic?
moritz a bit, yes
masak well, it's mostly a cultural thing.
Moukeddar_ lol 19:53
tadzik no, but heterosexual. I don't mind anyone doing anything, I'm speaking for myself
Moukeddar_ there's nothing wrong with hugs and kisses
tadzik I didn't say there is
moritz I don't mind either as long as no man tries to kiss me
masak "to kiss someone" is quite a wide phenomenon in English. could be anything from a peck to making out. 19:54
Moukeddar_ i kiss you = i love/like/respect you
masak or I'm the godfather.
lue masak: for some reason I thought your June 15 post would be about &chomp :) 19:55
Moukeddar_ hehe , you might
if you were they'd kiss your forehead
masak lue: oh! I didn't make the connection, even :P
wolverian I've been totally out of the loop when it comes to (#)perl6 for six months or so. anyone want to summarize what's happened? :>

TimToady given that no guarantees are made about threading hyperops, the best you can say is that it'll sleep from 3 to 6 seconds 23:24
and given that hyper specifically declares you don't care about side effect interactions, you won't get a better promise than that from Perl 6 23:26
hyper *does* guarantee to return the results in the original order though 23:27
Krunch i wasn't really hoping for more :)
TimToady so rakudo is correct there
the other failures were amusing :)
Krunch in p5 i ended up with perl -ne'fork&&sleep$_,print,last' 23:28
this is from dis.4chan.org/read/prog/1295544154 for people who didn't follow
sorear the niecza error is because somebody put token prefix:sleep { <sym> <O(%named_unary) } in the parser :) 23:29

daniel-s about modules and packages 23:53
what I get now is that there is a definite hierarchy
it goes packages -> modules -> class
where the lower down you go, the more functionality you have, but it covers a narrower part of the code 23:54
...well, nobody has corrected me, so I must be correct, :) 23:55
