camelia rakudo-moar ebccb2: OUTPUT«True␤Int|47556464␤Int|47556464␤»
TimToady this is incorrect, since $x and $y are supposed to be different variables
why VAR is not giving different WHICHes is perhaps the root of the problem; these are different objects 02:10
lizmat: ^^
in any case, the expression should be False, not true, since the identity of a container is its "location" 02:11

camelia rakudo-moar ebccb2: OUTPUT«True␤Parcel|(47195968)(Int|1)␤Parcel|(47195968)(Int|1)␤»
TimToady the problem seems to be tha that variables are dereffing on WHICH when they shouldn't 02:28
so it's ending up with the location of 42, or some such
rather than the location of the variable 02:29

sergot hi o/
cognome And if I has wanted the opening construct, I would have explicetely grouped it.
TimToady = only works on atoms, and ~ does not create an atom 06:26
cognome I think one can go either way for both but that should be said
Well '{' ~ '}' ... creates something pretty tight, I could have construed that as an atom :) 06:28
06:28 chenryn joined
cognome People are usually interested on the whole thing, not the opening construct :) 06:29
TimToady it expresses the relationship of 3 atoms, and it's not really a pattern matcher but shorthand for an error check
the purpose of it is to panic if you don't end up at }
you can't simultaneously do that and also have it participate in backtracking 06:30
cognome Well, I find it so convenient that I wanted to do more than it does :)
TimToady well, but we can't define it to do contradictory things, alas :)
cognome Anyway, the "work around" were easy enough. 06:31

TimToady you have to do make install in MoarVM 07:12

nine FROGGS: I just realized that v5 might become the basis of a P5->P6 translator... 08:10
FROGGS nine: when we can generate P6 code from AST, perhaps yes 08:11
nwc10 I'm not sure how useful a translator is, in the general case. Even if it gets to 100% of the syntax (which it can't) it won't cover semantics of the Perl 5 runtime that poke through 08:13
Python's 2to3 didn't exactly help set the world on fire.
so I don't think it's useful as a primary goal.
other people's opinions may vary, and please don't let me stop anyone having fun trying things. 08:14
nine nwc10: not as a primary goal, no. 2to3 failed because one would have to use it on the entire code base including all used libraries to make the transition.
But being able to migrate an application one piece at a time and being able to start with an automatic direct translation might help a lot. 08:15
nwc10 might. I'm still of the opinion that rewriting of working code from Perl 5 to Perl 6 is unlikely. 08:16
it's subsystem rewrites that we need to "capture"
which is why Inline::Perl5 is awesome
but, I repeat, these are my opinions. 08:17
nine Nobody's gonna rewrite working code just for the sake of it. Especially when with v5 we'll be able to execute P5 code faster. But if I have to do substantial changes to existing code anyway, I'll want to port it to Perl 6 first to be able to use the new features. That's when a translator might come in handy. 08:19
Even if it doesn't produce 100 % working code.

nwc10 jnthn: we have spectest failures. implication -> build builds, sanity tests pass, most spectests pass 13:46
jnthn raiph: Well, the answer to the nine question is "you leaked an exception from a C callback", usually... :)
nwc10: Ah, OK. Hmmm...that almost certainly means it's something to do with flaots...
raiph heh, you guys move way too fast
nwc10 jnthn: however, NQP nativecall test fails. I think it's confusion about 32 vs 64 bit. I've not dug into that one at all
nine that's exactly what I found out...and that getting refcounts in P5 XS code right is really hard.
nwc10 jnthn: might be. Seems to blow up with a NULL pointer in stringification. I'm not asking you to worry about this - I assume that I can figure it out 13:47
jnthn: actually, only question is "is there an easy way to disable spesh, "thing" by "thing", so that I can identify which one it is?"

timotimo that is optimize_smart_coerce? 14:06

timotimo it may need to check for VMNull on top of a null pointer in the facts->type slot

Avoid a bunch of str boxing in !cursor_pass.

masak spider-mario: see D4 of news.perlfoundation.org/2011/09/hag...mplem.html
14:56 fhelmberger left
spider-mario thanks 14:57
masak briefly, if you do `class C {}` in normal code, it registers with the package scope and you can use it directly.
if you do the same in a quasi, you don't expect to get a class C (or whatever) to play with. not until you install the quasi in some actual code. 14:58
TimToady it's the problem of generic code
masak yes.
TimToady so there needs to be a "compose" somewhere
moritz TimToady: yes, in a quasi
TimToady otherwise known as instantiation
not to be confused with instantiation :) 14:59
masak it's a bit of functions:invocations :: quasis:splicings.
moritz well, one could also argue it's a problem of scope
if all declarations were lexical, it would be much less of an issue
masak that's not the language I have to implement this thing in, though :) 15:00
TimToady in some ways it's easier with textual macros, because you know you have to reparse, and it's clear at what level the declarations happen
when "reparsing" must happen at a deeper level, it's a little more abstract 15:01
15:01 nam_ left
TimToady "what would the text that would have produced this AST have done besides producing this AST?" 15:01
masak right. AST macros are semi-digested already. the trick is keeping track of all the semi-digested information (tree, scopes, world-style declarations)
D4 is tempered a little bit for me by the fact that we now know that the foundation on which it rests needs to be rethought. 15:02
moritz you mean the macro part? or World? 15:03
masak the macro part.
TimToady or the grammar part?

moritz lizmat: to me, the solution is pretty clear
dalek p: 1058b96 | jonathan++ | src/QRegex/Cursor.nqp:
Various micro-optimizations to MATCH.

These avoid various bits of boxing. In fact, all of the boxing that we accidentally did in MATCH. In a parse-heavy benchmark such as the NQP JSON parser, this cuts the number of object allocations roughly in half by number (though since it cuts down on boxing, and boxes are comparatively small, it's a much smaller decrease on GC runs needed, from 29 to 25).
moritz lizmat: Parcel.WHICH needs to escape the characters ( and ) in the .WHICH strings from its elements 15:12
TimToady lizmat: yes, our current implementation of WHICH is subject to injection attacks
and as we know, escaping is only a partial solution 15:13
and bug prone
jnthn All todays patches guided by pfoiler++
uh
profiler++
15:13 dayangkun left
lizmat hence my reluctance to go down that path 15:13
I see .WHICH being used in 2 ways in the setting:
1. as a string, for typed hashes and sets/bags/mixes 15:14
TimToady identity is a sequence of assertions, any one of which can falsify
lizmat 2. for comparisons
TimToady but these assertions could be integer comparisons
lizmat for the typed hashes etc, we need a string
TimToady and integers are possibly easier to hash than chars
FROGGS tadzik: there is a message for tadzik2 from me :o) 15:15
lizmat but for comparisons, I would argue, I would argue we need some === overload that would do a sort of eqv on whatever the objects are
maybe an "eqw" operator ? 15:16
moritz or maybe we just need a single routine that can collapse a tree of ObjAt objects into a single one
lizmat moritz: how would that help value based objects?
moritz lizmat: what would be the difference between eqw and === ? 15:17
TimToady if your cryptohash is good enough, you can do the git trick, yes
TimToady thinks the string notion of identity is a bit misguided in the first place
lizmat === checks the stringification of the .WHICH object
eqw would do an eqv on the .WHICH of the object tree
eqw could be cheaper, as most === are not true 15:18
jnthn Let's be clear *why* ObjAt is currenlty a string. It's because the existing portable hash support we have over different backends, that was to hand when getting object arrays in there in the first place, was string keys.
TimToady you should be able to ask an object for a hash of its identity
15:18 zakharyas left
lizmat and could therefore fail on the first mismatch 15:18
15:18 larie is now known as fling
moritz lizmat: as long as that's something internal, and not another user-exposed equivalence operator, I'm all fine with that 15:19
jnthn That does not mean we should keep it that way; it was done that way so we could actually have object hashe at all, 'cus too many things blocked on them, and a passable-for-now implementation "now" beat a perfect one "later"
TimToady gets the feeling eqw is a bandaid over a suboptimal design, yes 15:20
we should fix the notion of identity to be composable
if you later have to serialize *that* in order to hash, so be it 15:21
lizmat quite likely so: but needing to build a string of a Set of 1M entrues for an ===, when you know the Set you're comparing with is most likely not the same
seems less optimal to say the least
TimToady but I was thinking of the precise phrase "injection attack" several days ago with respect to this problem
and that's exactly what moritz++ did 15:22
thankfully he did it with good intentions :)
lizmat (and has done before, I know, it wasn't forgotten moritz++)
TimToady but this really is a security issue, or governments would not issue us identity cards 15:23
lizmat how about we create a WHICH class, and that all .WHICH methods return an object of that type
moritz lizmat: we have that part already. It's called ObjAt 15:24
TimToady though the At is a misnomer
lizmat and then handle the comparison code (the "eqw" thing) in there
15:24 nbrown__ left
TimToady and the internal algorithm can remain hidden and optimizable 15:24
you do need to be able to ask it for a .hashval or so 15:25
15:25 nbrown__ joined
TimToady which it might or might not cache 15:25
masak hashing is a typical domain where not looking at how other big languages do things would be almost criminally stupid.
TimToady it's sort of a smart ID card :)
well, python has a way to ask objects what their hash is 15:26
masak I think you can get pretty far by doing `$hash = 31 * $hash + hash($part);` over all parts. 31 is prime and has nice optimization properties.

TimToady forgets what we were talking about
masak today's mini-challenge: (been a while since we had one)
you're given the text "The quick brown fox jumps over the lazy dog."
FROGGS shall we dance it? 15:31
masak and two operations: italic($from, $len) and bold($from, $len), where $from and $len work like in substr.
given an input of N such italic/bold operations, emit the most sensible properly nested markup of <i>...</i> and <b>...</b> tags on the text. 15:33
the task is interesting because (a) one has to decide what an operation on a "mixed" piece of text does, and (b) the operations are allowed to mis-nest, but the tags in the markup aren't. 15:34
moritz masak: what about mutliple-times bolding and italicing? 15:35
FROGGS right, operating on .words

TimToady and, actually, in the xor approach, you never actually have to locate the boundaries at all, since deciding the font is done on each character anyway
masak: as I said, impenetrable :P
masak heh :) 15:52
TimToady er, my previous point was in how your wysiwyg editor, not xml
15:52 denis_boyun left
TimToady s/editor/editor works/ 15:52
obviously xml is boundary oriented
unless you wrap each xml character individually :) 15:53
masak well, my solution would certainly make serialization easy by the end. dunno how elegant the tree transformation logic could be made, though.
TimToady which makes the boundaries Someone Else's Problem :)

if we would follow the lead of the .Set coercer, one could even think of .WHICH as a coercer to the identity of the object 20:13

TimToady that's interesting
TimToady expected the last 3 to be different

colomon TimToady: what you did is just a restatement of what Parcel.WHICH is doing (my last comment)

itz_ what is $?DISTRO and $?KERNEL supposed to return on non linux UNIX systems? 21:29
augustus quick question all, is there a replacement for plaeteria? where are we supposed to go to read all the p6 blogging? 21:30
lizmat $?DISTRO and $?KERNEL are still NYI afaik
timotimo augustus: raiph quite dilligently posts interesting stuff on reddit in r/perl6
lizmat $*DISTRO and $*KERNEL are
suggestions on what they should say, are welcome :-) 21:31
timotimo sadly, the planeteria domain has been taken directly after the current payment stopped
lizmat yuck
[Coke] timotimo: where are you getting your intel on that?
lizmat is there no time between taking it out of DNS and releasing the domain??
itz_ probably $?DISTRO.name I meant .. and I guess most of the time they are the same
augustus i thought planeteria was deliberatey shut down, are you saying it was just an oversight? 21:32
grondilu lizmat: after update and recompilation I still get identical scalars with (my @ = ^3).Parcel.WHICH;
raiph I typically post stuff to /r/perl6 stuff that isn't on planeteria. could we make /r/perl6 our new planeteria?
yoleaux 20:16Z <nine> raiph: I'd say it's really made possible by NativeCall. As NativeCall does conversion of char* and int to Perl 6 types for me and converts all other pointers to OpaquePointer types, I didn't have to figure out how to create such objects on MoarVM. The parts where I had to create such objects for Perl 5 I took directly from Inline::Python's source and conerted it to Perl 6.
[Coke] Yes, it was an oversight, the lead tech guy is working on restoring the domain and the service.
lizmat itz_: src/core/Distro and src/core/Kernel may contain non-linux specific code :-)
[Coke] raiph: I thought the point of something like planeteria was that you didn't have to repost. 21:33
augustus coke: ok thanks, good to know. i'll check back periodically and in the meantime check out reddit. does anybody have any idea what kind of readership it had? I know I check it compulsively, but the blogs never got many comments so I always wondered. 21:34
21:36 denis_boyun joined
[Coke] sorry, no aggregated stats, as far as I know 21:36
timotimo [Coke]: because planeteria is now owned by someone who is "parking" that domain
[Coke] I have a feedly subscription to r/perl6 which hasn't been updated in 90+ days. :(
timotimo: I have spoken to the tech lead for planeteria, who is working to restore service. 21:37
augustus do we have any stats on rakudo downloads etc? anything to tell us how many ppl are at least trying perl6?
[Coke] I suspect that a payment was inadvertently missed, but it sounded like he still had the opportunity to renew.

jack_rabbit IO::Socket::INET is not available through panda?
