MadcapJake ohhh, so the `(-)` turns it into a set?
psch ^^^ that's why .keys
yeah, the list gets promoted to a set, and the .keys call gives turns it back into a List
i'd guess in hindsight that the .cache call in that line isn't neccessary.. 05:40
MadcapJake interesting, is there a situation where the value of a set pair would be `False`?

zengargoyle ah, when i saw it without keys it was later .pick()'d to get a value.
so stayed a Set 05:42
MadcapJake That rotated line is really spiffy. Surprisingly readable too! 05:43

psch as in, whenever you don't enforce context onto something iterate-y, you still have the Seq 05:56
and if you iterate over a Seq more than once it complains
where "something iterate-y" means "something that could be lazy"

06:43 rarara joined
TimToady though poking the symbol into $*UNIT is probably wrongish, now that I think about it, since a subscope could have overridden the base op, and that should not leak out to outer scopes 06:45
dalek kudo/nom: 2856ed3 | TimToady++ | src/Perl6/Grammar.nqp:
autogen should go into current scope, not unit

Since a meta depends on the current base op, and that can be shadowed inside a scope, we should only install the autogen into the current lexical scope, and let outer scopes do their own autogen with (presumably) different base ops.		 06:48
rarara Good morning
TimToady it's not morning for 12 minutes yet :) 06:49

rarara Idem 06:54
Can somebody explain me the difference between the following two pieces of code? 06:59
my @a=(List(1,2,3), Seq(1,2,3)); for @a -> @b ($c, $d, $e) { say @b.WHAT; }
and my @a=(List(1,2,3), Seq(1,2,3)); for @a -> $b ($c, $d, $e) { say $b.WHAT; }
only the former works
dalek ast: 11681b8 | TimToady++ | S03-metaops/reverse.t:

TimToady @ caches the sequence automatically, $ does not 07:02

rarara TimToady: wouldn' be better for the subsignature to just consume the Seq? 07:13
in analogy to: my @a=(List(1,2,3), Seq(4,5,6)); my ($c, $d, $e) = @a[1]; say $d;
well, they are not really the same (the assignment doesn't check the correct number of elements) 07:14

Fix off-by-one error spotted by ShimmerFairy++
 10:27
lizmat I'm getting slightly worried about one aspect of the GLR with regards to spectesting that we've possibly overlooked 10:28
jnthn lizmat: Which one? :)
lizmat a difference in test result when pull-one was used, or push-all, or push-exactly, or count-only 10:29
jnthn BTW, from backlog: one of the assumptions of the GLR was that normal Perl 6 users will assign the results of operations that produce many results into @-sigil variables, not $-sigil ones, and those putting them into $-sigil ones would mostly be after the one-shot/pipeline semantics 10:30
So if folks are hitting a lot of "already consumed", nudging them towards using @ in the appropriate places will often be helpful :)
10:30 _mg_ left
lizmat also, I have my doubts about the default implementation of bool-only 10:30
jnthn lizmat: Ah, yes
We have a bool-only? Hm :) 10:31
RabidGravy tadzik, I'm wrapping it in a role for my own nefarious purposes so I won't have to type it that often ;-)
timotimo the tool jnthn suggested for seeing what lines of the core setting get hit by roast
lizmat yeah, I know, I invented it
jnthn The things people do when I ain't watching... :P
lizmat hehe
jnthn But it's probably fine enough 10:32
lizmat well, I either think we should force implementation of it
timotimo you invented that "lines getting hit" or bool-only?
jnthn I'd expect it to do pull-one and see if it gets IterationEnd or not, as a first guess
lizmat or we should let it default to True
jnthn Default to True sounds wrong...
lizmat well, a pull-one, e.g. in the case of a grep, is no guarantee of a result
timotimo default do Die
lizmat which would be the same as forcing to implement 10:33
jnthn lizmat: Huh?
lizmat default die is the same as forcing to implement ?
timotimo default to True seems very wrong to me, too

jnthn -1 to any more "forced" implementation besides pull-one, anyways :)
lizmat ok, that's clear
jnthn Waht does bool-only do now? 10:35
timotimo that's fair
lizmat pull one, if it's not IterationEnd, it's true
jnthn OK, so what I thought. :) Where does that trip us up?
lizmat well, it might set up a cache where there's none needed
so, I would like to see bool-only be non-constructive, if you will :-) 10:36
timotimo you mean "destructive"?
lizmat no, non-*con*structive
timotimo oh
jnthn Well, that's more a Seq-level decision, not an iterator API one
timotimo right, because if you pull-one, you construct the first value 10:37
lizmat yup
jnthn Oh...you didn't mean destructive :)
timotimo i thought destructive because that first value then gets unreachable
jnthn yeah, me too :)
lizmat ah, ok
timotimo reminds me of "antonyms"
lizmat that's another way of thinking about it: yes, in that view, non-destructive
jnthn lizmat: Do you have any concrete situations where working out if we would produce a first element is massively cheaper than actually producing it? 10:38
lizmat but we already make in non-destructive by caching it
timotimo that's true

lizmat although that would probably not used often 10:38
jnthn And is the current API not sufficient to just implement bool-only differently?
(In the iterator for split) 10:39
lizmat well, I could make a bool-only that doesn't call pull-one
but I wouldn't be sure if that didn't set up the caching anyway ?
timotimo i wonder if we want an iterator to have an attribute (/method) "can-cheaply-bool-only"
lizmat anyways, just something that was on my mind 10:40
jnthn timotimo: I prefer not; since the API here is mostly for improving performance, adding introspection isn't likely to help with that goal :)
10:40 Alina-malina joined
jnthn lizmat: What would set up caching? I don't think the caching actually causes any reification of elements right away anyway? 10:40
timotimo that's fair 10:41
lizmat jnthn: well, that's the thing, I'm not 100% sure, but it *is* another layer of indirection that may not be needed 10:42
but, let me just put a stop on this right now: let it simmer more in my mind :-)
jnthn ok :)
lizmat before I'm bothering you guys with it again :)
ShimmerFairy Would some kind of trait or pragma telling enums not to bother installing unqualified names be feasible at the moment? I tried using quietly { } earlier to at least suppress warnings, but that didn't work. (And besides, I don't want P6 to bother in the first place :P .) 10:48

nine: that's why I always do a "before" test run, so I can compare to the "after" run :)
nine ShimmerFairy: that's what everyone has to do if roast isn't kept clean. But I guess we have loads of developer time to spare. 12:54
[Coke] ShimmerFairy: I can't believe I'm going to have to spend time explaining this, in addition to spending time cleaning up your commits. 12:56
ShimmerFairy nine: there are lots of times I've had in the past where tests fail because of TEST_JOBS usage, or other reasons I don't know. So I guess part of the reason why I don't find it much of an issue is because I myself never trust roast to be "clean", for reasons beyond just "these tests should be fudged". 12:57
[Coke] If there are jobs that fail under stress, those need to be ticketed and fixed. we are also bad about that, yes. 12:58
but every failing test that we leave out there means that we are less likely to notice when new tests start failing. 12:59
12:59 tokuhiro_ joined
[Coke] you make it harder on the release manager, who needs to be fudging these tests so that on release, our users don't get failing tests to run. 12:59
nine lizmat: how do you do that? Right now I see the following test files failing: t/spec/S03-operators/autoincrement-range.t t/spec/S17-scheduler/at.rakudo.moar t/spec/S17-supply/throttle.t t/spec/S32-num/complex.t t/spec/S17-procasync/many-processes-no-close-stdin.t 13:00

ShimmerFairy [Coke]: I think part of my issue is that our current `prove` is quite black-n-white; it doesn't say "We passed the expected tests, but you're still SKIPping some" or "Good so far, but there's more TODO yet". It just claims "All test successful." when that ain't true. 13:07

ShimmerFairy [Coke]: does our current `prove` show that? If not, I still contend that saying "All OK!" when that's not the case is just lying.
[Coke] No, it's not prove.

[Coke] ShimmerFairy: I'm sorry you don't understand why we're doing it this way. Perhaps once I'm done going through and cleaning up roast, I'll take the time to write something up to explain it to you. in the meantime, please don't commit any more failing tests. 13:13
nine ShimmerFairy: as a developer I feel not helped at all. Quite the opposite. I did miss regressions I caused because I thought those tests were already failing before.
[Coke] Sorry that we haven't set a great example recently. There's a lot to do, and we appear to be spending some time on cleanup that I wish we didn't have to. 13:14
ShimmerFairy [Coke]: I usually don't, fwiw. I did it in this case because I felt it was more helpful than hiding a new bug (esp. since the test also doesn't crash the rest of the file). Also, to split hairs a bit I hadn't updated my rakudo yet, so for my local copy they were passing :P 13:15
13:16 weihan left
ShimmerFairy nine: I get that, and it hints to me that the spectest could benefit from a different way of handling TDD (since NYI vs. "my bad" is more problematic with something like our roast/), but I have no clue what that even means :) 13:16
13:17 weihan joined
[Coke] obviously, your local copy doesn't matter to anyone who can't use it. you -are- hiding the new bug. Did you create an RT? 13:17
to sum up: you're not the only developer here.
moritz note that roast is mostly used for regression tests, not unit testing 13:18
[Coke] As fun as it's been, I have to get to $dayjob. I'll work on cleaning up roast more on my break. Adios. 13:19
ShimmerFairy [Coke]: there's a reason why I didn't try using that as a serious argument, since I never believed it was one :)
moritz and for regression tests it's essential to not show breakages that have nothing to do with the changes somebody is working on

14:10 ely-se left
jnthn DBIish uses require, but the name form, not the filename form. 14:10
So it'd not be affected 14:11
PerlJam Perhaps the wild isn't wild enough for people to really be using the filename form. Once there's an influx of P5 programmers though, that's likely to increase. 14:12
jnthn Well, yeah, I was mildly pondering if it's unused enough I can just say "nah, we don't do it in 6.c" and punt the issue :P
That'd prevent use of it increasing too :P
PerlJam yep 14:13
jnthn So that'a also an option
The other option would be to actually add another method to the CompUnit::Repository interface to cover this case
And a CU::R::I could just say "no, I got nothing", and only a CU::R::FS would have much idea what to do about it 14:14

jnthn Indeed 14:36
Well, the latter is easier to fix :)
masak PerlJam: re "hallmark of good design" -- I guess it's the flip side of "make it easy for people to unintentionally do the right thing" (aka "Pit of Success"). if you realize this strongly enough on the design end of things, you will engineer for that to be possible, kind of.
timotimo right; we had an idea (but not yet a design IIRC) for having some piece of rakudo code-gen attribute accessors for us
jnthn aye 14:37
timotimo ah, something I still had a "problem" with was that every time we invoke the compiler, we'll be getting a separate CompUnit, is that right? 14:38
PerlJam masak: yes, kind of.
timotimo i suppose that could be cut down to a single CompUnit for each class that gets attribute accessors generated 14:39
jnthn Yeah, which means we needed to really find a way to use the currently executing compiler to ehlp us
PerlJam masak: for instance, I think Matz got a free lunch there in some sense because when I was using Ruby and didn't know how to do something, I approached the problem with "How would I do this in Perl?" and that, more often than not, led me down the right path.

retupmoca azawawi: :keep-filename tries to copy it to a temporary folder
right now I think you can leave that off, because we aren't using the 'store in a database with numbers as filenames' thing right now 15:42
15:42 AlexDaniel joined
retupmoca so the filename *should* be correct anyway 15:42
but I had to do that with bundled .dll files, because panda install would completely remove the filename, and windows doesn't like loading dll files named '37' :P 15:43
azawawi retupmoca: it was so revolutionary thinking into the future that it failed :)
retupmoca something like that :) 15:44
lizmat: that's something to think about for module database discussions in the future as well though - I'd rather not have to copy to a temp directory if I really need the original filename on disk
(with .dll files it's a bit of a security issue as well) 15:45
lizmat azawawi: wasn't that a matter of not having the right extension, though ?
retupmoca that may be - I know the extension straight up broke it 15:46
but I don't recall if there was an issue with the filename itself

gtodd how does one specifiy an input record separator in perl6 ? I know it has sensible standard default :-) but is it possible to set it to an arbitrary value to read data or does one take a more sane approach to that?
lizmat gtodd: you can use IO.open.split() now 15:50
it will take regexes also
jnthn probably will be working on getting any arbitrary string as a separator in next week 15:51
gtodd ah ok ... good so there will be no proliferation of switches or special values ... you just tell perl6 what to do
oh
lizmat well, in the case of split: yes
jnthn You can already do single char custom separator by setting nl on the handle, and I think as a named arg to open
It's multi-char separators that aren't yet handled 15:52

TimToady we need special values that a smartmatch can use to indicate success vs failure; Bool/Match/Nil/List all fall into this category
lizmat dinner& 16:43
TimToady when you write $foo ~~ bar() we have no idea from the syntax whether bar is intended to return a value to be smartmatched against, or is itself performing the smartmatch 16:44
so we distinguish some values that bar can return to indicate it has already done the smartmatch

psch the problem is mapping those lists over slices of the array (or range) you call the method on 20:04
flussence wow, there's a lot more modules using .trans than I thought; most of the web-related ones need it for basic escaping stuff. Making that faster's going to make quite a few people happy...
TimToady psch: that's not fast, that's lazy
I've been calculating permutations(9).elems for several minutes now 20:05
psch TimToady: oh. yes, that makes sense 20:06
i keep forgetting how useful laziness actually is
FSVO "useful"
tony-o lizmat: then how can i guarantee that any socket write is in the originating thread? 20:07
TimToady in any case .permutations[*-1] is a really slow way to write .reverse
lizmat tony-o: but using a Supply, I guess, and doing the write in an .act ? 20:08
although I'm not 100% sure atm, jnthn would know for sure
AlexDaniel is there any other way to insert an element into the middle besides using splice? 20:09
Hotkeys TimToady: It gets the last element. Would reversing and then getting the first element be faster?
timotimo splice is exactly how you do that efficiently 20:10
but you can also @foo[15..*] = @foo[16..*]; foo[15] = $new_elem
or something
got the = the wrong way around
AlexDaniel timotimo: that's ok. I'm just thinking if maybe there should be “&insert” thingy that will do exactly the same. Otherwise it is not obvious, but works for me 20:11

And NQP's is duplicated for every VM :/ 21:53

dalek kudo/nom: 94ce3cf | lizmat++ | src/core/Nil.pm:
Remove special casing of Nil.gist

This makes Nil.gist now appear as '(Nil)' instead of 'Nil', more in line with all other type objects. Also handles fallout of changes to S02-types/WHICH.t tests.		 21:58

AlexDaniel hm, it still mentions inf 22:10
lizmat yeah, but my point is that if you have an non-multi method in a class, that it will *always* be called, even if there are better matching multi's out there
psch is reminded of the .? discussion with zostay
lizmat assuming this is intentional, then it can know at compile time the method has a sig that will never match
psch lizmat: ooh, right. if we know we have only a not-multi hanging there we could opt it, yes
lizmat: oh, but shadowing through children..? is that an argument against it? 22:11
AlexDaniel lizmat: wait, what's the difference between "index out of range" and "effective index out of range"?
psch really isn't sure and will probably stop thinking about this in a bit...
lizmat AlexDaniel: the word "effective" ?
AlexDaniel lizmat: yeah, which means? :)
lizmat well, the *-1 is a "virtual" index that translates to an effective index 22:12
which is actually used to index

right!

psch lizmat: i think that's the general reason for "no compile time opt on methods" 22:16
lizmat: i recognize that that's the same argument from the other side, though. for me this comes down to "people smarter than me thought about this a lot more than i did" 22:17
so, sorry if this seems not-particularly-contributive
lizmat well, you're thinking about it, that's quite a lot already!
