moritz you might be able to PARROT_INLINE instead of 'inline', I think it is automatically replaced by 'inline' or the empty string, depending on what Configure.pl detected 10:59
mls_ That's exactly what I'm changing right now ;)
plan for today: merge my pct changes to parrot, submit exception/leave handler changes 11:01
to be reviewed by jnthn++ (and maybe pmichaud++)
moritz mls_: does your exception changes fix the return value of try { } blocks when an exception was thrown?
mls_ yes (except that I don't know what the return value should be) 11:02
moritz either the exception (so same as $! on the outside), or a Failure that wraps the exception
mls_ I think it currently "returns" the exception
moritz wunderbar 11:03
mls_ we can easily adapt that to anything TimToady++ comes up with

PerlJam GlitchMr: replace the - than are meant to be ranges with .. and replace [ with <[ and ] with ]> and you're there :) 13:17
GlitchMr: add some whitespace for readability too
moritz__ PerlJam: you can have him read the docs too, that way he might pick up a bit more Perl 6 :-) 13:21
PerlJam Sure, but I'm not going to fall into the #perl trap of "RTFM" at every turn (even when it's the right technical thing) because that's a part of the #perl-culture that isn't very friendly. 13:23
I'm perfectly happy giving out intellectual fish while encouraging someone to learn how to catch fish for themselves. (which you've already done, so I didn't need to fill that niche :) 13:24

[Coke] that looks suspiciously like a builtin rule, also.
GlitchMr Thanks for help... I cannot understand those Perl 6 rules...
But it makes sense...
PerlJam GlitchMr: what do you have trouble understanding? 13:27
moritz__ well, \w matches all those alphanumeric things, but also non-ASCII alphanumerics
GlitchMr Well, it's just long article...
moritz__ so it wouldbe [\w|'-']
so you need a bit more time
GlitchMr Well, I haven't really programmed in Perl 5... 13:28
PerlJam GlitchMr: oh, so you lack a regex background in general?
GlitchMr Well, I used somewhat preg_replace() in PHP... but I guess it's different that this
PerlJam GlitchMr: i.e., all regex would be unfamiliar to you and difficult to understand at this point?
GlitchMr Well, not exactly 13:29
I can understand that [] is like (?:)...
en.wikipedia.org/wiki/Perl_6_rules 13:30
It just wasn't on Wikipedia...
<[]>...
whatever...
PerlJam GlitchMr: ah, that's why you should read the synopsis as moritz__ suggested.
GlitchMr And doing [a|b|c|d|e|f|...] would be really weird
PerlJam GlitchMr: it's the definitive source for the Perl6 regex syntax 13:31
GlitchMr I was trying [[a-z]]... nope

[Coke] moritz: autounfudge could be moved to roast without any modifications, I think. (except perhaps removing a default value for implementation and making it a required argument) 14:18
(might also want perl6-limited, at that point, and then implementaitons can just make sure there have something called ./perl6 that works) 14:19
moritz [Coke]: or just base the invocation form on the implname 14:22
14:22 risou_awy is now known as risou
moritz my %invocation = (rakudo => [$^X, "tools/perl6-limited.pl"], niecza = [qw/mono run/Niecza.exe/]); 14:23
[Coke] moritz: mono may not be the right way to run Niecza. 14:24
so I'd make that a command line arg, then.
moritz [Coke]: is there a better, more generic invocation?
flussence the only more generic way I can think of would be to use binfmt_misc in the kernel and invoke the .exe directly... 14:26
moritz flussence: well, the first part kinda contradicts "generic" :-) 14:27
flussence generic on the fudge script's side, at least. I''m not sure how other *nix OSes would work then though. 14:28

TimToady masak: regarding "allowed to panic, once", it's something I said verbally several times over the years, mostly in unrecorded Q&A sessions. Eventually I decided it needed to be written down, and S01 seemed like the right place to do it. 15:15
but we were dealing with panic from the beginning: A01 has "Nobody should panic when we..." 15:16
and somewhere near the beginning I had the thought that it's fine if we all panic, as long as we don't all do it at the same time. 15:17
dunno if that got written down anywhere
15:19 LuRy left 15:24 daniel-s left, LuRy joined 15:25 LuRy left 15:28 MayDaniel joined
TimToady is starting to think that making ».foo recurse by analogy to dwimmy «+» is probably a mistake, having wanted ».[0] to work more often than wanting a tree walk 15:34
perhaps it should be limited to one level of *shaped* array 15:35
15:35 meraxes left
TimToady or maybe it should stay at one dimension even there 15:35
and something slightly less huffmanly short be used for deeper mappings 15:36
there's a missing .treemap method currently too
so we'd have » means .map, and »» or some such means .treemap 15:37
and abandon the "foolish consistency" with infix dwimmery
15:39 drbean left
TimToady this is a direct result of actually trying to translate a program that runs under b to running under niecza and nom :) 15:39
moritz I for one won't miss the tree semantics of ». very much 15:40
15:40 alester joined
TimToady I know you were one of the people I argued with :) 15:40
moritz (that wasn't intended to be a "told you so" or anything) 15:41
TimToady but I'm thinking about humbly invoking Rule 2. :)
dimensional slicing seems a more appropriate use of "vectorizing" than treewalking does
15:44 drbean joined
TimToady and the unary tree walking is not at all the same dwimmery that is used in infix hypers, where it means replicate to match teh other side 15:45
so it was a false consistency from the start
[Coke] moritz: (generic niecza invocation) nope. that's the best one. but I wouldn't hard code it because it won't work on windows, e.g.
(... not that that matters right now.) 15:46
TimToady another thing I'm wondering; if we get constant folding right, then there's little harm in saying that "foo" xx $count is really a thunky operator that evaluates its left side every time (it *is* doubled, after all) 15:49
so xx would become more like && and friends
but the thunk is on the left 15:50
so rand xx 20 would produce 20 different random numbers as people always seem to expect
otoh, (rand for ^20) is not so far off from that, huffmanly speaking 15:51
but my argument is more about what people expect xx to do 15:52
and that xx already looks a bit thunky 15:54
and that a good optimizer will notice it doesn't have to re-evaluate things that won't change 15:55
sorear good * #perl6 16:01
tadzik hello sorear
TimToady would like sorear++'s opinion on the two proposed mid-course corrections above 16:02

sorear mberends++ was complaining about how [ 0 xx matrixColumns ] xx matrixRows didn't DWIM the other day
TimToady the tradeoff with that one is that we force someone to use a temporary to suppress it

TimToady I believe it's called a macro :) 16:59
moritz I believe something easier to used and better fleshed out than macros could be very useful here 17:00
TimToady s/useful/abuseful/
moritz and macros don't fall into the "abuseful" category? :-)
TimToady "hard things should be possible" 17:01
moritz thought more of the "simple things should be easy" part
TimToady mebbe, mebbe not 17:02
just write a macro macro that rewrites macro signatures :P
17:03 aindilis joined
TimToady but it's possible that it would be good documentation to mark the parameter 17:03
and we do, after all, use 'is' to mark other forms of parameter passing
moritz collects macro use cases for masak++ 17:04
TimToady so maybe that's the right way to go; me is just being a knee-jerk conservative, after thinking two impossible things before breakfast already
PerlJam TimToady: if *I* were the language designer, that's what I'd do .... but usually that means it shouldn't be generally done :) 17:05
TimToady so maybe we shouldn't have a 'macro' declarator, but have an 'is ast' trait 17:06
though note that macros *must* be predeclared, so maybe it's good to force recognition of 'is ast' and 'is thunk' by requiring 'macro' up front 17:08
moritz sounds sane

jnthn [Coke]: Not likely, that looks like a memory leak somewhere
mls_ No prob. I hope the implementation matchers the spec.
jnthn mls_: OK, great, thanks. I'll try and look at it soon, but I'm snowed under with $dayjob. 17:37
So it may take me a little bit to get to giving it a proper review.
mls_ jnthn: Don't worry. I also ran out of time today, so I'll commit the leave implementation on monday 17:38
TimToady jnthn: did you see my proposed » and xx revisions above? (already respecced the xx)
jnthn TimToady: No, not yet.
TimToady thinking of reverting » back to flat rather than tree-ish, since it seems more useful in practice 17:39
jnthn Ah, OK
TimToady and the dwim analogy with infix was flawed anyway
jnthn has too much of a headache to really think about anything much properly right now :/
diakopter :(
TimToady well, it's basically back to b semantics, though we might have a »» variant that preserves the deep version
jnthn TimToady: Both do seem to have use cases. 17:40
17:40 GlitchMr joined
TimToady I just found myself wanting to write ».[0] over and over 17:40
jnthn TimToady: Are we just talking about the ». case here?
TimToady or ».<foo>
both unary cases
not infix
jnthn OK, but that's really the same case after desugaring.
TimToady yes 17:41
jnthn >>+<< would still recurse?
as in, go deep...
TimToady so » would turn into ordinary map, while »» (or whatever) would be .leafmap or some such
yes, infixes would remain unchanged
jnthn It's totally possible I'm missing something, but that inconsistency seems...oddish.
moritz jnthn: thing is that you usually want to apply infix operators to scalars, but method calls not so often 17:42
TimToady and we've got Z+ for the flat semantics as well 17:43
jnthn ah, true
17:43 mj41 left
jnthn It just feels like it may be one of those inconsistencies that ends up nagging at us with time, until eventually having to be fixed. 17:44
I can see the argument that they want different defaults though.
Well, to the blury extent I can see anything right now. :)
Having a .leafmap that it can desugar to also makes some sense. 17:45
TimToady we could possible force »+« flat, and require «+» for any non-flat but symmetrical depth
jnthn Not sure the name is spot on
TimToady we probably need to think about tree visitation patterns a bit more
jnthn Hm, but that feels like overloading a simple distinction with multiple meanings.
[Coke] nom: $a='aaa'; $a ~~ s/a$/b/; say $a;
p6eval nom 1c2c2d: OUTPUT«===SORRY!===␤Symbol '$a' not predeclared in <anonymous> (/tmp/pg6wp7_ZKC:1)␤»
[Coke] nom: my $a='aaa'; $a ~~ s/a$/b/; say $a;
p6eval nom 1c2c2d: OUTPUT«aab␤»
[Coke] where is s// defined? 17:46
jnthn TimToady: (tree visitation) yeah, but we have multi dispatch for really fancy trees, so we probably don't need to go to town too much on it.
TimToady doubtless there some adt-ness that needs to be considered from the FP realm too, but I don't want to make your headache worse
jnthn Thanks. :)
