pmichaud TimToady: ... is "take" considered an instance of abnormal control, in the sense of being trappable by CONTROL handlers...? 02:53
*abnormal control flow
02:54 sunnavy left
TimToady presumably 02:54
at least as currently implemented
pmichaud well, I mean more "as designed"
TimToady it doesn't really have to be control flow, if it merely knows where to put the next value 02:55
pmichaud I'd prefer it not be control flow.
TimToady fine by me 02:56
pmichaud in some sense it is, in another it's not, since as far as the block is concerned execution continues immediately following the take anyway :)
it's more like an interrupt than a control flow break :)
TimToady certainly we want to maintain the right to optimize 02:57
pmichaud yes
works for me.
skids Well, someone will come looking for a coruotine construct if take stops behaving as one.
pmichaud skids: I'm not changing that. 02:58
adu TimToady: you're such a libertarian 02:59
pmichaud There are just cases where take can be smart enough to recognize that it's safe to store the value somewhere and proceed without immediately doing the control jump.
02:59 adu left, adu joined
skids Ah, good, I am all for optimizing those too :-) 02:59
pmichaud when it's not safe, it does the continuation/jump bit. 03:00

TimToady you can say that again

TimToady Mouq: yes, re irclog.perlgeek.de/perl6/2015-06-10#i_10729270 a deepmap is intented to retain structure, so there's that's gone buggy with some of our GLR stuff, and will need fixing 04:19
*something
Mouq Okay 04:22
TimToady jnthn: the intent of having a .parsefile in the first place is to capture the filename for use in error messages 04:23
otherwise it's rather uselessly redundant with .slurp.parse
well, .parse(slurp) or some such 04:24

Add answer to skids++'s e71c0a1 question.
 04:25
Mouq Part of me, after implementing it, is still uncertain about »+» creating lists of the same type as were passed, until we get coersion worked out better :/
TimToady that seems right to me 04:26
pmichaud I suspect a lot of new information will fall out of the new GLR semantics
er, phrased that wrong
I suspect we'll have a lot better picture of how it should work once the initial GLR semantics are in implementation 04:27
I'm very much liking the model that is emerging from thoughts/discussions
it feels clean, elegant, and (potentially) fast

Add "Sublist" to the brainstorm.
 04:51
pmichaud Also "SList", which combines "sublist" but maybe sounds a bit like "slice". :-)
04:52 SevenWolf joined
TimToady the conjectured type won't replace Nil, only Empty 04:54
pmichaud correct.
Nil ends up being quite orthogonal to lists, I think. 04:56
as in, it doesn't have any special listy properties.
pmichaud adds to S07
TimToady I just was reading a partial context line, and didn't see the pre-GLR note on Nil

Add note about post-GLR C<Nil>.
TimToady kinda wonders whether our new type is really just an iterator, rather than something you ask for an iterator
pmichaud it's certainly Iterable.
and in pre-GLR, all Iterators were Iterables. 04:59
Mouq Also, "Expand"? (Seq bikeshedding)
TimToady
.oO(Shoehorn)
Hoist 05:00
pmichaud I knew I'd be opening the bikeshed paint store with that commit. :)
Clip, Cut, Paste were ideas coming from the notion of film editing. :)
TimToady Splice
pmichaud I thought of Splice, but it's too close to .splice for my taste.
TimToady well, rather similar idea 05:01
pmichaud yes, but part of me feels that .splice should then return a Splice. :)
TimToady whatever it is, Foo() has to feel like Empty 05:02
pmichaud thesuarus.com only knows about the verb form of "splice", and the noun definitions I've seen think of a "splice" as the whole result of the join, and not the piece being joined
TimToady More()
pmichaud I kind of like Seq() 05:03
I didn't at first, but it's growing on me.
Mouq To bad we already used Mu :P
pmichaud Lu
TimToady Moo 05:04
we were wanting a Dog type...
pmichaud I'm also toying with the idea that the type object itself disappears in a list.
05:04 lolisa left
pmichaud like Empty does now. 05:04
m: say Empty.defined
camelia rakudo-moar 15c6fb: OUTPUT«False␤»
pmichaud so then one could just return Seq
and not have to do Seq()
TimToady but Seq doesn't feel empty
pmichaud (or whatever it gets called) 05:05
TimToady Slot
pmichaud Hole
TimToady Virus
pmichaud Gene
TimToady Intron 05:06
Slip
as in, "slip this in"
but also "slip one cog" when nothing is there
pmichaud "Welcome to Pm's Bikeshed Paint Emporium! Today we have a special running on all sorts of list-related terms" 05:07
yes, I like the double-meaning to slip
I was thinkng "slip by this one"
TimToady and it implies "sneaky"
pmichaud Sneak
(slip is better)
Mouq Pm()
pmichaud are you implying I'm empty? :-)
Mouq You just fit in so well 05:08
pmichaud I think I'll tentatively go with Slip for now, I like it better than Seq

pmichaud fwiw, I tried really hard to convince myself that C<Dog> could work. :-P
and perhaps C<Tac> is too much "you think that's cute today" 05:11
05:14 llfourn left, skids left
pmichaud I wonder if the result of an infix:<...> should naturally be a Slip 05:30
(idle thought)
TimToady we might implement the postulated foo(@inner): @outer using a slip of some sort too 05:33
pmichaud this feels very much like a primitive type we've been missing for some time :)
TimToady .u ､ 05:34
yoleaux U+FF64 HALFWIDTH IDEOGRAPHIC COMMA [Po] (､)
pmichaud I get a box for that char in my font. 05:35
TimToady .u ⸴ 05:36
yoleaux U+2E34 RAISED COMMA [Po] (⸴)
pmichaud same there. :)
TimToady looking for non-Texas forms :)
"raised" is cute though
pmichaud well, we want to make sure it's visually distinct from normal commas, too.
TimToady u ⨩ 05:37
.u ⨩
yoleaux U+2A29 MINUS SIGN WITH COMMA ABOVE [Sm] (⨩)
TimToady has been considering various Texas forms
05:37 prevost left
TimToady ,, or \, or ^, and such 05:37
the (,) ain't so bad except it would imply a set operator 05:38
pmichaud yup
TimToady <,>
pmichaud I conjectured @, at one point.
but too sigil/twigilish 05:39
TimToady it's kind of a shame that _ is considered alpha 05:40
as a "flat" sugar
other possible flat sugars: *() *: 05:41
would obviously have to win under LTM, but fit nicely with * for slurp
pmichaud there's always *** :-) 05:42
that's the Alaska form. :)
TimToady too bad there isn't a monster truck glyph 05:43
05:43 RabidGravy joined
pmichaud aha 05:44
the O_O operator
TimToady maybe we should use snowman for hierarchical, and comet for "flattening" :)
pmichaud O_O looks like a steamroller :)
TimToady O¯O 05:45
pmichaud I'm pretty sure someone can create a Texas monster truck
but for that matter, how about infix:<slip> 05:46
I really don't expect it to be common at all.
TimToady o̿o
pmichaud (perhaps I'm wrong about that with all of the other flattening/itemization changes we're making... perhaps it'll be very common)
TimToady I considered infix:<slip>, but while it's huffmanly ok, it just doesn't quite feel right for some reason 05:47
pmichaud or even prefix:<slip>
TimToady prefix slip is close to your one-level flat
pmichaud yes, and it fits with the other "list" and "flat" contextualizers.
and then you can do return slip;
as well as return slip()
TimToady but a reduce on the infix is probably sufficient instead of a prefix 05:48
pmichaud indeed
TimToady return Slip; ain't so bad
pmichaud yeah, but Slip.new(1,2) isn't so much fun.
It works, but....
TimToady [,,] 1,2 05:49
pmichaud I suppose we can do Slip(1,2), but that feels wrongish also.
TimToady not opposed to a slip listop
pmichaud return [slip] 1,2 feels interesting also
the "slip" almost looks parenthetical :)
FROGGS hmmmm, 'return Slip' would be identical to 'return Panties' where I am 05:50
pmichaud FROGGS: TMI
TimToady the Slips I'm familiar with are not identical to Panties...
pmichaud WTMI

TimToady @x X (@y Zslip @z) feels odd 05:52
@x X, (@y Z^, @z) seems more better
or @x X, (@y Z\, @z) 05:53
so I'd like it to seem like a comma variant
pmichaud I'd be okay with ^, or \.
TimToady that's probably what bothers me about slip
pmichaud er, \,
yes, I prefer a comma variant of some sort also.
I just haven't come up with one I like better than slip. :) 05:54
I just haven't come up with one I like.
TimToady [\,] is bad though

yoleaux U+275F HEAVY LOW SINGLE COMMA QUOTATION MARK ORNAMENT [So] (❟)
pmichaud I'm going to go with "slip" for now, knowing we'll likely change it to something comma-based. 05:58
I definitely like the prefix "slip" form. 05:59
06:00 bin_005 left 06:01 bin_005 joined
TimToady the thing I like about ,, though is that it kinda implies the two commas in the upper list on either side of the bit we're slipping in, a kind of comma-hole 06:03
pmichaud put a "hole" between the commas, then. 06:05
like ,O,
but not alpha
so that it doesn't look like a typo but is obviously deliberate. 06:06
06:10 diana_olhovik_ joined
pmichaud perhaps we could do ,, and make it illegal to mix ,, and , in the same chain. 06:12
3,,4 # okay 06:13
3,4,,5 # error
3,(4,,5) # okay, but same as 3,4,5
oh! 06:14
for that matter, even if someone typoed the ,, they'd end up with the same result. 06:15
(I think)
I can probably find a case where that doesn't work.
TimToady well, 3,4,,5 would already be an error, since two list assoc have to be the same operator already 06:18

quietfanatic Insert() was what I was thinking 06:18

TimToady extra arg to 2nd TOP 06:20
quietfanatic But the signature of first TOP is (ASDF: *%_) 06:21
according to introspection
so why would anything be calling anything with two args?
RabidGravy struggling to reproduce this "smallbin double linked list corrupted" thing in a bite size chunk of code 06:22
it appears to only happen when running tests with "panda-test" 06:23
which is odd 06:24
quietfanatic And those two multis really shouldn't affect one another. Even if this is an unlikely use case, it looks like a bug to me. 06:25
RabidGravy and also makes it difficult to run valgrind on it
06:26 telex left
TimToady quietfanatic: you're probably completel freaking out the LTM analyzer by mixing a rule and a method... 06:26
quietfanatic Well I wouldn't freak out if I were it. :) 06:27
pmichaud Yes you would.
The entire regex engine is a big mess of "OMG WTF I AM SO FREAKED OUT!"
if you're wanting to put the action methods into the grammar, how about just using a closure? 06:28
FROGGS m: grammar ASDF { multi rule TOP { { say "WAT" } }; multi method TOP (*@, *%) { say "hello" } }; say ASDF.parse("asdf", :actions(ASDF))

pmichaud rule TOP { ^ asdf $ { $/.make: "asdf" } } 06:28
quietfanatic Yes, that's what TimToady replied offline
I recall somebody several years ago on here telling me not to do that though 06:29
pmichaud you don't get inheritance/substitutability, but I suspect it works just as well.
TimToady there was a point where make didn't work in rakudo if you used it there
but that's been fixed
FROGGS quietfanatic: yes, it becomes more dirty and dirty when your grammar grows
quietfanatic ah, maybe that wasa it
pmichaud well, putting the two methods in the grammar is going to get dirty as well :)
FROGGS true 06:30
TimToady the main reason for separating out to a separate class is that you can use the same grammar with different actions
pmichaud agreed.
quietfanatic ah, that makes sense too
TimToady such as a pretty-printer
pmichaud that, and also to make it easier to read
I always found it really hard to follow parsing when the action code was intermingled in the rules.
quietfanatic it's easier to read but there's a lot of coupling of method names and organization 06:31
pmichaud yes, I didn't find a way to avoid the name coupling.
tbh, I didn't expect it to be adopted. :) :)
TimToady yeah, and it's difficult to optimize away the double dispatch too
06:31 domidumont joined
TimToady we really need a composition operator of some sort 06:31
with a grammar and a set of actions 06:32
06:32 mattp__ joined
pmichaud 'action' keyword, perhaps? 06:32
grammar Something does SomethingActions
TimToady well, important thing is to set up some wrapping scheme so only a single dispatch is needed
FROGGS I guess the proto has some trouble coping with a rule and a method in the ASDF example here...
quietfanatic or hey, what about
FROGGS I bet it is auto-gen'd wrongish
quietfanatic grammar X is Y { 06:33
whoops, hold on
TimToady this strikes me as the same problem as wrapping role's BUILD submethods around the class's
pmichaud compose the actions directly into the grammar, and find a way to link the two.
quietfanatic grammar X is Y { method TOP { callsame; $/.make: whatever; } }
TimToady but you don't want the grammar saying what it's mixing in 06:34
quietfanatic You can just inherit the grammar and override and supercall all its methods
06:34 Klaudioh left
quietfanatic Y is the original grammar without actions. 06:34
pmichaud could be a runtime mixin
anyway, I vote post-6C :)
TimToady well, I wanna rework the fate system first, I suspect
and that probaby wants to be pre
FROGGS quick! rewrite all the things! /o/ 06:35

TimToady and the fates cleanup also probably gets us <*...>
quietfanatic now why doesn't that inheritance one work? Another regex engine freakout?
FROGGS yeah... I still wonder if I will every use that

pmichaud sleepytime for me
be back tomorrow evening
TimToady sleep/drive well 06:50
quietfanatic You know, if regexes (as methods) simply returned what they either matched or made, this would be really easy. 06:51
TimToady yeah, always returning both is kinda silly 06:52
quietfanatic method TOP { return process(callsame); }
currently they return Mu
TimToady there are a few places in the P6 grammar that revisit the submatches after make, but not many

RabidGravy marnin
quietfanatic Not that I want to encourage yet another big refactor before Christmas, but having regex routines return their matches is more functional, more object-oriented, more composable, and simpler. 07:01
moritz .tell ab5tract nice. A few small comments: 1) you should probe for the 'fmt' executable before using it. 2) I don't like interactive prompts much; maybe just show the docs for all matches (much as 'man less more' does)? 3) the routine/method distinction in the user interface is weird, because Method ~~ Routine 07:02
yoleaux moritz: I'll pass your message to ab5tract.
quietfanatic and probably more optimizable.
okay I'm done for the night. Later everyone. 07:03
moritz quietfanatic: there's just one problem: those lists need to be lazy
quietfanatic which lists?
moritz and lazy lists aren't very fast
the list of possible matches
quietfanatic ah
I don't entirely understand the situation I guess 07:04
Do you mean this would require more lazy lists, or it would prevent them from working right? 07:06
well, I should really get to sleep soon. I'll be back later. 07:07
07:07 quietfanatic left
moritz it would mean more places where we need lazy lists, which are expensive 07:07
so a performance problem
pmichaud which are *currently* expensive
moritz yes 07:08
when they become faster, it might be worth evaluating the regex design again
RabidGravy does ':::' as a "package part separator" actually exist or is it being silently ignored or turned into something else? 07:09
moritz after all, the lazy list of matches/cursors is what the design docs say :-)
pmichaud regex methods return cursors, though. Making them return match objects will get expensive.
07:09 _mg_ joined
pmichaud (and returning match objects directly was pge's original model, which needed to be abandoned in favor of cursors) 07:11
RabidGravy lizmat, I don't think I'm going to be able to golf that crashiness - it doesn't even do it if I run the tests in question on their own, only with "panda-test" 07:19
but github.com/jonathanstowe/Audio-Snd...ree/crashy reliably does it with 2015.05-76-g94eed8f built on MoarVM version 2015.05 07:25
pmichaud Oh! The Slip type may also be a way to relax the need for immutable iterators! 07:30
very intriguing.

RabidGravy (^(10)).map({$_}) isn't lazy is it? 07:40
pmichaud depends on the target 07:41
it can be lazy
07:41 [TuxCM] left
RabidGravy it's assigning to an array 07:41
pmichaud you didn't show that part. Array assignment is currently eager, yes. 07:42
RabidGravy I'm just looking for a qucker why to do "@foo = gather { take @bar[$_] for ^10 }"
pmichaud why use gather/take there? 07:43
RabidGravy where infact "10" could be a fairly large number
dalek ecs: c756e93 | pmichaud++ | S07-glr-draft.pod:
Fix grammatical error.
 07:44
RabidGravy pmichaud, because it was the first thing that fell under my fingers ;-)
pmichaud at the moment gather/take is inherently slow.
(GLR will fix this.)
RabidGravy I know, hence "looking for a qucker why"
pmichaud still, a .map would almost certainly be a lot faster than gather/take.
RabidGravy but the actual number of items may be in the tens or even hundreds of thousands 07:45
pmichaud so?
you already have a map there, even using the given/take 07:46
you aren't avoiding the map
moritz the 'for' does a map too
and for/map can also be lazy
pmichaud take @bar[$_] for ^10 is the same as (^10).map( { take @bar[$_] } )
it actually compiles that way.
07:47 bin_005 left, bin_005_c joined
RabidGravy right, the question was probably more "will (^1000000).map({$_})" evaluate the range to make 1000000 items up front? 07:48
07:49 brrt joined
pmichaud no 07:49
range generation is lazy too :)
(in the current implementation, yes, it's possible you'll end up with 1000000 integers in memory before they get GC'd. But GLR is going to address that also.) 07:50
at any rate, it doesn't create 1000000 items "up front"
RabidGravy oh wait, "*** Error in `/home/jonathan/.rakudobrew/moar-nom/install/bin/moar': free(): invalid pointer: 0x0000000005af7cf0 ***" 07:51
pmichaud at least, it's not supposed to create them up front. I can't say what it's actually doing with the various "optimizations" that have been added since I last looked at the code :) 07:52

Reading the glr-draft, I get this feeling that "flat" should really be an adverb on "for". 12:19

Ven admits to not really liking that `my @a = _` is different from `@a = _` 12:20
(it just feels weird to me, probably because I'm not used to it...)
I have one question, though: what are [] and {} useful for if they don't itemize? (I mean -- what makes them different from `()`) 12:21

12:37 Ven left 12:39 Ven joined
timotimo you have to put spaces in that case 12:39
we don't force people to put spaces around infix ops yet
pmichaud the difference between [] and () is that [] creates an Array and {} creates a Hash 12:41
timotimo that's not the difference between [] and () :)
pmichaud sorry
the difference between [], {}, and () is that [] creates an Array, {} creates a Hash, and () creates a List.
Better? 12:42
timotimo fair enough
so it's no longer about the scalar around it, but about the scalars inside
pmichaud and the type of the container itself
timotimo right 12:43
but the differentiation between array and list is mostly scalarification of the things inside?
pmichaud yes 12:44
timotimo 'k
pmichaud and perhaps also that arrays are "flat" 12:45
timotimo OK, so it's mostly LoL, rarely AoA?
pmichaud Not sure I follow that part. 12:46
timotimo well, you wouldn't use arrays for nesting, was my thought
pmichaud you can use arrays for nesting, yes.
my @a = [[1,2,3], [4,5, [7,8]], 9] # does what you expect.
timotimo so in what way are lists considered "flat"? 12:47
muraiki is there somewhere where an explanation of these things are written down? besides the irc logs of course ;)
timotimo er, i meant: "arrays considered 'flat'"
pmichaud once something goes into an array, it's already "flat". Flattening an array just returns the array itself, because all of its elements are itemized.
timotimo oh
i'd call that "firm" instead of "flat"
TimToady I don't think [] will flatten inside, though
by default
pmichaud right 12:48
anyway, I have to go check out of hotel and hit road -- bbl

TimToady AlexDaniel: re irclog.perlgeek.de/perl6/2015-06-11#i_10738316 it's just a hash of match lists, so unordered; .caps is what returns captures in order, but that's less efficient since it basically has to sort them for you based on position 14:21
gtodd1 hoelzro ... well adding or die; makes it die :-) 14:24
hoelzro at that line 14:25
14:27 bjz joined
hoelzro gtodd1: excellent 14:29
if you'd like to dig more, I could use a trace of the program, or a print out of what errno contains
otherwise, I can spin up a FreeBSD VM later and have a look 14:30
this raises an interesting point of how to deal with C-defined constants and such
14:31 bjz left, bjz joined
hoelzro I forget - is there a way to get errno from Perl 6? 14:39
or does one need a wrapper function to get at it?
lizmat good *, #perl6 14:44
hoelzro: I don't know of a way to get at errno. suggest NativeCall for now :-) 14:45
AlexDaniel TimToady: I've already reported it: rt.perl.org/Public/Bug/Display.html?id=125391
hoelzro greetings lizmat
so you think I should include a helper library?
14:45 grondilu joined
AlexDaniel TimToady: so it seems like it should be even less efficient because it does not check .to right now 14:46
but I think that correctness is more important in this case
otherwise why bother with sorting at all, just shuffle it and let the user think about the rest 14:47

Parcel looks like C struct containing List... and with Captures it creates some strange device :) I wonder from where it was borrowed... 16:33
also Ranges looks complicated a bit... I think they are mainly syntax and when they are accesed they immediatelly slipping into List... 16:36

timotimo i think in some places we search for a line number annotation and set -1 if we can't find one, and that probably gets reinterpreted as unsigned at some point 21:31

ugexe im starting to wonder if some moar async IO problems are caused by "/* For now, take last character. */" in re: setting input line seperator because in IO::Socket::INET $sep-len is used in a substr (so if a "\r\n" is passed it would leave "\r" but $sep-len would still be 2). JVM properly splits multi character input line seperators, and hence properly handles `start { <handle chunked encoding or keep-alive> } 23:22
` (moar does not)
my $sock = IO::Socket::INET.new(:host<httpbin.org>, :port(80)); $sock.send("GET /stream-bytes/1024?chunk_size=100\r\nHost: httpbin.org\r\n\r\n"); my $data = utf8.new; await start { while my $d = $sock.recv(:bin) { $data ~= $d; }; }; say $data.bytes; # returns 1024 on jvm, 0 on moar 23:23
