TimToady you mean more like ::($from)::{$_}, or maybe ::($from)::($_) 01:10
or ::($from ~ '::' ~ $_) 01:12
sorear No
I do not want to look up a name
I just want to construct a string
TimToady then the way you wrote it first seems pretty okay 01:13
but I don't know what you mean by 'idiomatic' 01:14
sorear "{$package}::$name" just looks a bit ugly to me
TimToady perl6: my $from = "abc"; $_ = "def"; say "$from\::$_" 01:15

moritz it's much more important to put whitespace around the infix operator 12:19

Add initial version of nqp:: pseudo-opcode space for low-level primitives.
moritz pmichaud: do the control nqp:: opcodes take closures? 14:59

pmichaud moritz: yes, bootstrapping. 15:53
eventually ?? !! will be defined in terms of nqp::if() . 15:54
Agreed on "uc" versus "upcase" -- fixing.
15:54 slontec left
moritz pmichaud: but isn't control flow usually bootstrapped by the code emitting part? 15:54
pmichaud nqp::if() is just another way of saying PAST::Op(:pasttype<if> ... ) 15:55
moritz I mean, the PAST if-block takes care of that
ok
pmichaud all of the nqp:: "opcodes" are really just ways of requesting specific PAST nodes
it even occurred to me earlier that we can do nqp::stmts(...) and create PAST::Stmt blocks
i.e., eventually it would be possible to write all of nqp using nqp:: ops :) 15:56
(well, maybe not all, but we can get darn close)
what nqp:: really does is give us a functional syntax to map to the capabilities of whatever virtual machine we happen to be on 15:57
(as exposed by PAST)
eventually PAST will be written in nqp, at which point we'll be very self-hosted
15:58 cotto left
pmichaud About 20 minutes ago I was thinking of nqp::parrot(...), which performs an operation on Parrot but is a no-op everywhere else. 15:58
moritz might be useful, might be dangerous
pmichaud well, I was thinking of the case of something like the 'compreg' opcode. 15:59
Eventually HLL::Compiler will have its own "lookup a compiler" equivalent, that can be independent of compreg
i.e., it'll keep its own table of compilers 16:00
but if we're running on parrot, we'd like to go ahead and register the compiler via compreg anyway
so: nqp::parrot(pirop=>'compreg', ...args...) can do that for us. It lets us execute a parrot opcode, but gets ignored by non-parrot vms. 16:01
16:01 Yaakov joined
pmichaud anyway, yes, there's a lot of new capability here to be explored :) 16:01
I'm eager to start converting nom to using nqp:: instead of pir:: where we can 16:02
moritz shouldn't be too hard, once you've bootstrapped 16:03
16:03 Yaakov left
pmichaud oh, I can add nqp:: syntax to nom now :) 16:03
no bootstrap necessary, at least for the CORE.setting part
moritz ah, I misread
I thought you meant nqp
for nqp you'd need bootstrapping 16:04
pmichaud nqp already can start using nqp::
that's how it's able to test it :)
(nqp:: is already built into nqp.)
moritz but not in the stage1 compiler, is it?
pmichaud rakudo uses the stage2 compiler
anyway, "make bootstrap-files" will put it into stage 0 :) 16:05
moritz but you couldn't use nqp:: in NQP's Action.pm unless you bootstrap, right?
moritz just wants to check his sanity
pmichaud right
s/unless/until, at this point.
moritz right
pmichaud doing that now :) 16:07
the opcodes I'm not entirely happy with are nqp::bindattribute and nqp::getattribute. They feel "long", and I'm not fond of "get" either. I'm thinking of just nqp::bindattr and nqp::getattr 16:09
or even just nqp::attr instead of nqp::getattr
PerlJam whenever I see "get...", I tend to expect there to be a corresponding "set..." 16:10
(just a data point)
16:10 mj41 left, strider__ left, strider__ joined
pmichaud PerlJam: I'm the same way. I'm still stung by Parrot's over-misuse of that term. 16:11
16:11 MayDaniel joined
pmichaud and I think I'd be much more explicit by using "bind*" instead of "set*", so that means "get*" should probably disappear in favor of something else 16:12

JimmyZ though I don't like C# and Java :) 16:26
pmichaud well, if this goes well, then you'll be able to use Perl on the CLR without having to deal with C# :-)
16:26 Trashlord joined
PerlJam "grab" works for me (I tend to favor something with 4 letters to match "bind" in the absence of some mnemonic device) 16:27
JimmyZ never learns commercial language
pmichaud I'll brainstorm a bit more.
JimmyZ I would like fetch
PerlJam so will there be 3 variants or just 2? 16:31
pmichaud ?
PerlJam bind, fetch, and "change the thing bound" ? 16:32
or just bind?
pmichaud bind, fetch, and maybe store
where store means "put into the thing"
PerlJam ok
pmichaud i.e., we bind a lexical symbol, and we can store into a container
(also following some of the p6 terminology here :)
PerlJam You can't go too far wrong following the lead of a linguist when doing languagey things ;) 16:34
pmichaud ...how does this look to folks? gist.github.com/1038259 16:35
PerlJam less verbose than before. 16:36
JimmyZ maladjustment 16:37
PerlJam stupid question: We can't have ops that operate on boxed ints?
pmichaud in parrot, that would mean going through the vtables 16:38
which would mean creating a vtable for every type
which currently means that you either write that code in C (not portable), or you suffer an absolutely gigantonormous performance penalty as you jump through inferior runloops to get to the pir that implements your vtable 16:40
16:41 aidan2011 left
pmichaud if you mean "can we create ops that automatically unbox the ints for us"... we might be able to do that, but jnthn++ feels pretty strongly at this point that we should keep coercions a bit more explicit (I agree with him for now) 16:41
s/ops/pseudo-ops/
s/coercions/(un)boxing/ 16:42
PerlJam I was thinking ahead a little to the mythical VM that caters to Rakudo's needs and wondering how this code would change to run on both that VM (or a VM like it) and Parrot 16:45
pmichaud I think the code might be the same -- on that VM the unbox_i opcodes would be no-ops (and thus optimize out)

pmichaud blog post draft -- comments welcome: pmichaud.com/sandbox/lists.html 19:38
moritz nice one 19:41
sorear TimToady: 'no strict; $x = 5; my $x; say $x' # What should this do in Perl 6?
pmichaud feels a little airy, but maybe I can add more down-to-earth stuff in a future post
masak pmichaud: reading that draft, I'm reminded of what I like about the Perl 6 design process: we're all building towards Perl 6, but we don't exactly know what it is yet. but "we know it when we see it" -- we know what Perl behaves like, and we often realize we have a number of expectations on Perl 6 too. 19:43
how list laziness interacts with arrays is one example.
it feels like it "falls out" of our expectations and our vague notions of what "Perlish" behavior is.
19:43 robinsmidsrod joined
pmichaud in this case it's more like "here's how we think it works, nope -- that's definitely not perlish, let's try this inste.... oops, that doesn't fit either, how about ..." 19:44
PerlJam I like the paragraph with the analogy of quantum physics and chemists
mberends pmichaud: a few short code examples (you're very good at those) would reduce the airiness
masak once I designed a chess variant. it made me realize that I have a lot of vague notions of "Chessish" behavior that made the variant "design itself" in spots. :)
19:45 ingyfoo joined
pmichaud mberends: I'm trying to decide if it's better to put this up now and concrete examples later, or to have this wait for the concrete examples. It might be a day or two before I can get the examples in, which makes me think "post now and again later" may be the better approach. 19:45

19:45 sunnavy left
pmichaud tadzik: hmm, the post is really more about the state of Perl 6 list implementations :) 19:48
tadzik oh, ok :) 19:49
TimToady sorear: obviously it should say "'no strict' not allowed in strict mode" :) 19:50
PerlJam pmichaud: will S07 mention all of those listy things you talk about in this post?
pmichaud PerlJam: definitely.
it pretty much has to
TimToady sorear: seriously, rather than just throwing variables into the current package like P5, we should consider whether assuming an implicit 'our' makes more sense 19:51
pmichaud they all relate pretty tightly --- indeed, most of them were developed in response to "hey, lists don't work"
19:52 Raynes left, Raynes joined
PerlJam The only one I don't really have a firm handle on are LoLs. I'd like to see a blog post about them at some point if you're taking suggestions 19:53
pmichaud Yes, I think that's a blog post on its own. :)
19:53 sunnavy joined
pmichaud And I can write that post as soon as I have a handle on LoLs. 19:53
masak PerlJam: I think LoLs are inherently sludgy, not just for you.
pmichaud Which will probably happen just about after the time I finish the first draft implementation of them :)
thou pmichaud: i'm looking forward to your S07 rewrite; there's some stuff in S02 that is hard to understand without knowing the difference between LoL context, list context, list vs Array vs. Seq, etc., and I've still not seen a good description of how all those terms relate
pmichaud thou: as masak++ said, some of them are still fuzzy -- they're waiting for an implementation to sort them out. nom is likely to be that implementation that does the first batch of sorting :) 19:54
masak how do LoLs and captures interact? &zip takes a LoL as an argument, doesn't it?
thou yeah, it's exciting. jnthn++ pmichaud++ !
PerlJam thou: it's easy ... all you have to do is hang out on #perl6 and participate in every discussion relating to lists and then pay attention to what the collective has decided does and does not work. ;-)
thou hehe 19:55
working on it.
pmichaud zip takes a capture, its signature binds the capture into a LoL
masak PerlJam: I wish that weren't so true... :)
19:55 cbk joined
masak pmichaud: yeah, I guess that is pretty easy, actually. 19:55
pmichaud well, there's still some trickiness in that we have to make sure that &infix:<;> dtrt :-)
er, semicolon in arglists, too 19:56
thou and the relationship of get() and getarg() may be a good way to explain things, too -- dive down to that lower level with an example or two
masak pmichaud: did you catch TimToady's comment about ; not being an infix?
pmichaud there is no get() and getarg() in the new implement
thou oh, well, nevermind then
hehhe
pmichaud masak: yes, thus my correction. it's an argument separator
as well as a statement terminator
masak pmichaud: it's only the latter, but the constant folder catches it. 19:57
IIUC.
pmichaud token semiarglist {
<arglist> ** ';'

masak oh, ok.
PerlJam The last sentence of the 5th paragraph may come back to haunt you. "...while Perl 6 programmers can do a lot of useful chemistry without having to be aware of the gory details underneath." I'm *so* reminded of leaky abstractions there. 19:58
As long as they can be gradually aware of the gory details thought, everything is fine. 19:59
s/ght/gh/
pmichaud PerlJam: some chemists do need to know about the quantum mechanics underneath, yes. :)
masak it's hard to get a precise understanding of it without going into the gory details, probably.
pmichaud I didn't say you can do all chemistry without having to be aware of the details, just that you can do a lot.
TimToady y'all make it sound like chemistry isn't Compleatly Gory in its own right... 20:00
pmichaud anyway, it certainly wouldn't be the first statement that comes back to haunt me. :-)
I think one of my first mis-statements was: "Perl 6 compiler pumpking? Sure, why not?" :-P 20:01
masak hugs pmichaud
TimToady that wasn't a statement; it was a question
pmichaud see! that's the sort of haunting I get! :-P
masak mis-question... :)
tadzik it's just that no one answered
TimToady well, the Spirit of Christmas Future answered by pointing at your grave.. 20:02
masak no-one knows the answer.
pmichaud and if I understand correctly, it's really an "interrogatory statement".
masak it's really an interrogatory statement?
:P
PerlJam heh
TimToady it was a derogatory instatement... 20:03
pmichaud looks over the precipice of having any sort of discussion with TimToady++ on the meaning of words and language and decides to back away slowly.
