TimToady but it should really support coercive keys, since the default is essentially Str() 00:00
that is, coerce to Str
and uint8() should surely allow coercion from Int 00:01
but coercion types are still fairly recent

jdv79 hmm, i think i just read that part wrong. i read it as implying there is a case where a module could be declared inline and be automatically imported. 00:09
rjbs Hm. I need to do complex validation of new objects. For example, $.x + $.y must be odd. I thought I could do this in BUILD, as one does in Moose. Not so: can't call the readers on a partially constructed object. 00:10

TimToady you can cheat with self.x + self.y 00:11
rjbs Okay.
Thanks, that helped.
TimToady or you can write your own BUILDALL that calls the builtin and then tests
which is cleaner if you want to allow derivation
or you can write your own constructor that tests after the .bless 00:12

raydiak is there a way to specify different git commits or tag for different versions of your module? eg if someone does use Foo:ver<1>, and installed Foo from the ecosystem is now at ver 2, great it gives a better error than just running until it breaks, but how can you tell it where to get ver 1 from? 06:32
I guess I'm wondering if there is a way to support something along the lines of panda install Foo:ver<1> or --ver=1 or so from a single module on the ecosystem, instead of distinct modules like FooV1, FooV2 etc which kinda defeats the purpose of all our nice versioning stuffs 06:37
06:40 Sqirrel left
raydiak the real thought which led to this was "I kinda wanna put this thing on the ecosystem, but I might want to keep radiacally changing the api/syntax for a while", so if anyone has a different answer to that dillema besides more useful versioning...cool :) 06:41

ugexe me and tony-o have been working on that ourselves 07:05
raydiak oh neat, how so? 07:08
ugexe other solutions just tag releases with a format vXX.XX
raydiak doesn't sound unreasonable
ugexe a combination of meta.info analysis, maintaining clones of authorities, package management integration crap to make it easy to do it a specific way 07:10
raydiak sounds like two changes to panda: to make --ver pull a specific git tag, and to allow it to install multiple versions in parallel instead of overwriting existing 07:12
then you can leave meta.info out entirely
though I guess it'd be better to declare what versions are valid and available or not in the meta.info, without fetching and grepping a list of all the git tags 07:14
ugexe not doing it in panda. and the meta stuff lets us do thing like flatten the dependency tree out as much as possible without having to serve out the meta of all packages
raydiak well ultimately the goal, at least my thought was, to allow users to install the proper version of the module to satisfy the dependency...how not doing it in panda? 07:16
ugexe yes, but how do you know what dependencies your dependencies have? you dont know until you download it. no reason that list couldnt be squashed into a de-duped tree so you can go right into paralell downloading/testing 07:20

rjbs Say I read a UTF-8 bytestream from a file, then decode it. Is there a way to get back the exact characters that were encoded in the bytestream, if they were not normalized? 11:31
timotimo if you first read it, then decode it, you still have the original ;)
FROGGS no
when we normalize, we lose information 11:32
timotimo i've claimed before that this is dangerous for filenames
rjbs And is there a way to decode a string without NFGing it?
decode to a string
jnthn rjbs: You'll be able to get it as a Uni
Not as a Str
Str means NFG
Uni will give you an array of Unicode "as they were"
FROGGS like if the bytestream contained a ö as o + marks, then it won't end up being that 11:33
rjbs jnthn: but it's nyi?
timotimo NFG and Uni are very much I, jnthn++
jnthn rjbs: Uni is, reading one directly from a file isn't
Or Buf -> Uni
rjbs jnthn: That's cool, how does one get a Uni? (I don't see it on doc.perl6.org)
jnthn They're not *hard*, I just didn't do it yet
Yeah, Uni is quite newly I
Uni.new(...codepoints here...)
rjbs Cool. And will Str coerce to Uni via NFC or something? 11:34
or must it be explicit?
jnthn Str.NFC gets you a Uni
And Str.NFD and so on
rjbs Right, but then I need to detect that what I got was Str and not Uni. Which is fine...
jnthn But by then you've doen the NFG round-trip 11:35
Note that NFG is entirely internal
So output is NFC
rjbs I can just write a multi, I suppose, where the Str form calls the Uni form with str.NFC.
sure
jnthn You're going to have to go out of your way if you want to work with normal string data and not have it be normalized on input.
rjbs Okay, all very helpful!
jnthn++ 11:36
jnthn For one because it's almost certainly never what you want in normal use cases. :)
rjbs jnthn: What do you mean when you say "with normal string data"?
jnthn rjbs: Uh, I mean, if you want to do text processing and not be under NFG semantics.
rjbs Okay. That word "normal"... :)
jnthn Yes, that was unfortunate :P 11:37
rjbs $buf.decode($encoding, :Uni) ? :)
I'm afraid it's something I'm likely to need, but I know it's not the common case, and don't mind some hoops to jump through.
jnthn Well, one reason it's NYI yet also that when I mentioned something like that, TimToady wasnt' sure .decode with a named arg was the right way to expose it.
Though it's mostly just that I didn't get around to it. 11:38
rjbs I *definitely* am not sure, as I'm still flailing about and speaking p6 with a weird outworlder accent.
11:38 jdurand left
jnthn I'd be surprised if there are that many cases where it's an issue for anyone. 11:38
rjbs Da, el buf sui very suggoi! 11:39
timotimo SUGOOOOIIII desu ne
jnthn For one, within ASCII and Latin-1 then the NFG round-trip is a total no-op
FROGGS not so for e.g. utf8
rjbs In this case, it is a potential issue for people in my very very niche market doing very very niche-again things. So I'm not worried, as long as it's somehow possible eventually.
11:40 laouji left
FROGGS so utf8 -> nfg -> utf8 results in input ne output 11:40
that's also the reason why we need buf/utf8 to become more Stringy
rjbs ...at least sometimes. Right, that was quite clear.
jnthn FROGGS: Correct, though what I said above was more "if you're using codepoints within the latin-1 range", which still applies even if you encoded them as UTF-8 11:41
rjbs btw, is the best way to iterate over codepoints with $str.split('') ?
jnthn The best way to go over codepoints is to do .NFC.list or .NFD.list
timotimo that's outworlder accent for $str.comb :)
jnthn .comb is grapheme level
FROGGS isnt there supposed to be a .codes or .codepoints method? dunno if this repr is still valid 11:42

rjbs Great, thanks. 11:43

colomon: maybe that's related
TimToady having looked recently at the implementation of callframe, I'm not terribly surprised...throwing a fake exception in order to collect a backtrace from which we fake up objects that pretend to be frames seems a bit roundabout... 16:10
colomon bartolin++
TimToady: what does “skip onlystar on CALLER” mean? 16:11
TimToady if you have a proto whose body is defined as {*}, it's not counted as the caller of the multi
it's as if the caller of the proto called the multi directly 16:12
colomon and that’s the default proto?
lichtkind TimToady thanks man looking foreward to see you again in granada
TimToady colomon: yes
colomon bet that’s exactly it
TimToady I didn't change callframe
callframe actually has nothing to do with CALLER currently
CALLER and other PseudoStashes are implemented with low-level nqp ops that access the frames directly 16:13
colomon TimToady: you say that, but it’s in a multi sub with a default proto and changing it to callframe(1) fixes the seg fault
TimToady the default proto is often optimized away anyway, so it could be a similar trigger, yes 16:14
the bug I was working on was that an implicit (autogenerated) proto was not optimized away till after the first call
so you had to say CALLER::CALLER:: on the first call, but CALLER:: on subsequent calls 16:15
callframe could easily suffer the same issue, I suppose
an explicit proto is a workaround
colomon and that fixed things
TimToady but I didn't change how things actually get optimized, just compensated for the inconsistency 16:16
16:16 kaare_ left
TimToady callframe probably needs the same compensation, unless the optimizer is made more consistent 16:16
Erendis42d bbl<3 16:17
TimToady unless, maybe, the fix I did to the autogen also fixed callframe, maybe it already skips onlystars, but didn't have the info because the autogen didn't install a &?ROUTINE symbol 16:18

jnthn About this one: 17:20
my $r = start { sleep .25; say $*E; }; my $*E = 5; await $r;
We currently look up $*FOO down the caller chain (only).
And the caller chain of the thread that runs the start block is unrelated to that of the thing that does "start" 17:21
I dunno if we're *meant* to do something else, but we've been getting away with doing it the current way for...ages. :) 17:22
jnthn is gonna eat, then will get back to fixing stuffs :)
TimToady so it's really getting the worker thread's caller, eh? that seems not very...useful... 17:24
jnthn Not even that 17:26
Every thread's call chain bottoms out at the start of the thread.
The call stacks are independent.
TimToady I get more than that when I list callframes though
seems 17:27
but anyway, how hard would it be to fake caller back to the start?
jnthn Well, you'll be able to see the infrastructure that is pulling tasks out of the todo list
Hmm

timotimo can't do that with the evalbot
naptastic Very well, then.
Makes sense.
After all, securitah :)
Would be nice to be able to open into a scalar, at least; though I'm sure that's not a super common need.
timotimo please explain what "open into a scalar" means? 18:38
i never perl5'd, you see
masak timotimo: think it means just "store the file handle in a variable". :) 18:39
timotimo oh, that's cute
is that what the barewords thing is with perl5?
no, not barewords. what was the term?
something glob?
naptastic no, I mean
open (my $fh, ">", \$scalar);
and if you print {$fh}, the output goes into the scalar. 18:40
I use it in testing, if some subroutine wants to read a file and I can't guarantee the file exists. "Here's an example of what such a file might look like," I say, handing the subroutine a scalar-ref instead of a filename... 18:41

pmichaud lizmat++ asked me this question in Oslo, and I came down pretty strongly on the side of pick($n) should always return a List. 20:58
the fact that some scalar values autopromote to List doesn't resolve the problem, because we also have to worry about the (user-defined) types that might not.
masak let me see if I understand you correctly. 20:59
pmichaud and, the bigger problem is when picking from a list of lists, or a list of mixed scalars-and-lists
jnthn We long ago decided not to keep the thing where a one-item Parcel dissolved into that item, as I remember it.
masak you're proposing breaking the current behavior of .pick() for consistency
vendethiel thinks .pick should return an item, and .pick($n) a list as well
tony-o_ vendethiel++
masak so that all current code that relies on .pick not being a list will have to be rewritten to .pick[0] 21:00
pmichaud I don't know that that's what I'm proposing. I don't know where it's been established that .pick() should be the same as .pick(1).
I'm okay with .pick() returning a single element, while .pick($n) returns a list.
jnthn masak: .pick returns a single elemnt, as we just saw
masak: And .pick($n) a list
masak ok, so .pick() just becomes distinct from .pick(1) -- ok
I'm less against that. :)
FROGGS jnthn: seems I can serialize the data from with CUR::Installation when I push it through to-json/from-json first... 21:01
pmichaud I do know that having .pick($n) do different things depending on the value of $n is a Bad Idea.
FROGGS jnthn: so I might have some object in the structure that do not like serializing
21:01 muraiki left
pmichaud I also know that Bool.pick probably doesn't want to return a List 21:01
jnthn FROGGS: Maybe, yeah...guess that can be golfed 21:03

zacts hello 21:22
I'm going to be studying some programming language design 21:23
and some basic linguistics for fun
I got some books
but they are mostly lisp books
I wonder which resources may be helpful for eventually hacking on rakudo
(or even an alternate implementation)
jercos probably all of them
zacts I do know of appel too
ok
andreoss m: use warnings;

FROGGS jnthn: I was able to bootstrap panda :S
jercos I mean, that's just my opinion, a great amount of general programming knowledge can come from specific teachings about unrelated languages. 21:24
zacts I don't mean to just read books too, I just didn't know if any stood out as great compiler / interpreter design and implementation books
jercos: I'm reading a bunch of lispy MIT Press language design books first
as lisp is so easy to parse, and I can implement language semantics without a ton of parsing 21:25
jnthn FROGGS: Why is success so ":S"? :)
FROGGS jnthn: I had to also scdisclaim the sc I create in serialize, because otherwise it would refer to that SC when we serialize again in the same process
jnthn: because I can't believe it :o)
zacts but I'm really interested in the practicality of perl5 and perl6 (I'm afraid of perl5 src, but perl6 seems more well designed for newbies to get involved with core rakudo hacking)
FROGGS I've got mixed feeling, is all :o)
zacts I just love perl and regex, and the way it maps to my brain
jnthn FROGGS: :)
cognominal what is the appropriate way to augment par of the setting without getting an "is closed". In other words, I want in some places an augmented setting. 21:26
*augment part of the setting
jercos zacts: I agree with your observation, perl 5 is difficult to get into the source of, perl 6 is much more transparent.
jnthn zacts: There is an NQP and Rakudo internals tutorial
zacts oh neat
FROGGS next up is making the string heap sane, cleaning up moar and implementing the json fallback (for when we recompile rakudo)
but that happens tomorrow
jnthn: thanks a lot btw
zacts is the tutorial the github one?
jnthn zacts: github.com/edumentab/rakudo-and-nq...ls-course/
There's PDFs 21:27
zacts yeah
cool

zacts I'm also working through a few MIT opencourseware linguistics courses and books 21:28
anyway, I may try to make a Perl6 minikanren module
minikanren.org
^ minikanren is a DSL for logic programming
although, indeed this would be at the level of Perl6 and not the interpreter 21:29
cognominal btw, as a sequitur to my question? is there a tutorial about this setting business. The stuff in S02 about all theses pseudo packages makes me dizzy.
zacts anyway, heading to a music lesson. laters
21:29 moritz_ is now known as moritz

Erendis42d aaaw
vendethiel is there a difference between "at the moment" and "at this moment" in english?
masak I like how Perl 6 often turns user confusion into informative error messages.
TimToady a slight difference
vendethiel masak: rust also does a really good job! 21:50
only think I regret in rust error messages is that it's often a bit *too* wordy when explaining, say, how some code was macro-generated, including all the innerworking parts
masak vendethiel: I can imagine. gotta try Rust.
TimToady "at the moment" is vanilla for 'currently' or 'in constrast to some other time' 21:51
"at this moment" would be a marked form emphasizing this moment to the exclusion of any other moment

timotimo so ... did anybody try the Proc::Async workload again with newest rakudo? 22:02
TimToady I tried it this morning and it failed, lemme try now
jnthn Some of the exceptions you ended up with are ones I managed to make go away, but I've still got crashes in the IO::Socket::Async under load. 22:03
And the next issue looked like a parallel GC issue. "Fun!" 22:04
TimToady restart-concurrent still has about 5 failure modes 22:05
jnthn Well, that's down from 8 or so :)
TimToady P6opaque: no such attribute '$!tappers_lock' is the most common
jnthn ooh
Is the latest restart-concurrent somewhere somewhere?
uh, one somewhere :)
...damn, now I have data races too :P 22:06
TimToady there's a github of it, though you have to remove a spurious return
timotimo a gist*
TimToady raw.githubusercontent.com/kgoess/r...restart.p6 is the original 22:07
my copy is identical except for s/'return %result'/%result/ 22:08
it also does: *** Error in `/home/larry/nom/install/bin/moar': double free or corruption (fasttop): 0x00000000021ae9a0 *** 22:09
and sometimes Cannot invoke this object (REPR: Null) 22:10
and occasionally just hangs
oh, and once I got This representation (Null) does not support elems 22:11
jnthn Ugh
But yeah, reproduced here
TimToady it's a really good test case, for some definition of good that ain't :) 22:12
looks slightly *nix centric, I guess
but I suspect it doesn't much matter what commands are run 22:13
jnthn Yeah, I tweaked them all to Windows equivs
TimToady I think once in the last 100 times I've run it, I got the actual desired output, which is something... 22:14
