TimToady if there were, it would be from reordering operators via precedence, I suspect 00:00
but mostly I just see O nodes copied up the tree
as for viv, there are still a number of missing action methods, I expect 00:01
mncharity re loop, ok. could be me. running STD_blue_run on elf_h_src/CommandLine.pm, even with a branch-local() %seen counter limit of 30, I was still hitting "seen this node too many times". I'll explore. 00:03
00:04 alester joined
mncharity not something to worry about. I'll report back. 00:10
TimToady well, lemme know if you have an example--I think I know where the bug might be
gotta wander off &
mncharity bye. tnx for the help
re viv, it looks like STD_blue will just continue using the class-STD tree directly, rather than switching to viv. since viv wasn't actually labeling the nodes, but rather depending on "no :=" etc for STD-specific guessing, I've just added that dependence to the existing STD_blue tree walker. 00:15
simpler, at least for now. 00:16

pmurias_ when do you have a problem with circularity? 14:21
mncharity ... see a node again. current "answer" is include it a few more times, in case the AST->IR converter needs it, then punt. possible alternative is "just don't include the SIGIL field". another possible answer is "stop being careless - the tree is fine". we'll see.
re when, STD_blue_run --format=p5a 14:22
not sure I'd call it a problem, well, not a real one. :) but an issue. 14:23
pmurias_ you could save circularity with assignment to a variable
or assume that AST->IR won't need it
mncharity yes, that one (won't need) 14:25
:)
14:25 lichtkind joined
mncharity basically, circularity is unexpected, probably shouldn't be there, and would require some small work to deal with. so "before simply adapting, try knocking it off". 14:27

@tell mncharity yep, that's why I'm writing "viv --p6", to see what's not there that should be. I figure if I can reproduce the original exactly then I'm not forgetting anything crucial. 15:47

ruoso TimToady, re: Foo::Bar.randommethod()... my reasoning was that *method* invocation applies to Classes, not all types of packages... therefore Foo::Bar wouldn't be found as a Class... unless we accept that all types of packages can be coerced to classes to do some basic things... otherwise. Foo::Bar.WHAT would return 'Package' 16:25
TimToady, I do understand, however, that WHAT is a macro, but I'd rather accept the coercion to keep the semantic consistency... 16:27

TimToady pmurias_: no, if it's not a known type it 18:05
is a function 18:06
packages are considered degenerate types

azawawi what the correct way to read a line from stdin in p6? 18:09
TimToady =$*IN 18:10
PerlJam greetings
TimToady or =<>, if no command line args
PerlJam I still want to write =<$*IN> sometimes 18:11
azawawi what about 'my $foo = $*IN.readline;'? 18:12
i noticed that pugs also allows bare readline...
TimToady not sure if that will be official
azawawi $*IN.readline or readline alone or readline? 18:14
TimToady any of those
azawawi thx
TimToady but likely there's some single-dispatch api for iterators, and whatever that is... 18:15
so maybe $*IN.shift or some such 18:16
18:16 ab5tract left, hercynium joined
PerlJam $*IN.more_please 18:16
TimToady whatever the multi-dispatch prefix:<=> calls underneath
pmurias_ TimToady: sorry, i should reread code before misleading others

TimToady so almost certainly *not* readline

azawawi rakudo: my $foo = =$*IN; say $foo; 18:20
pmurias_ OTOH it would be cool if it spawned a new bot waiting for input

under rakudo, only =$*IN and $*IN.readline currently work 18:22

PerlJam TimToady: why isn't $*IN.shift blessed? Or have you just not thought about it in enough detail beyond "not readline"?
18:27 jeja joined
TimToady several reasons 18:28
one of which is confusion between multiple dispatch apis and single dispatch
another of which is the principle of "just do it like P5" 18:29
yet another is "filehandles are just iterators"
vs "filehandles *aren't* just iterators"
18:30 zamolxes left
TimToady for instance, suppose you want to generalize =<>, which does double iteration 18:30
18:30 pmurias__ joined
TimToady =@filenames doesn't read the lines from each file like =<> does from @*ARGV 18:31
@*ARGS rather
lambdabot Unknown command, try @list
TimToady not sure whether that worthwhile
*that is
and maybe there's something going on with a slice of iterators 18:34
and =[;] @filenames woudl be what =<> is really doing 18:35
more succinctly, =@*ARGS gives you the next filename, whereas =@@*ARGS gives you the next line 18:38
or maybe something inside out from that
PerlJam is *so* glad he's not a language designer :) 18:40

TimToady well, what are you asking, really? 18:50
pmurias_ i see VAST::Methodcall nodes in VAST and they seem strange 18:51
TimToady it's just a precedence level, really 18:52
so anything postfixey tends to look like that
except for ++ maybe 18:53
pmurias_ why aren't VAST nodes subclasses of Match? 18:54
TimToady because they're not parse trees, they're abstract(er)
pmurias_ is VAST intended to diverge much from the parse tree? 18:57
TimToady it's intended to be something that is easy to walk and spit out p5 so I can replace gimme5 18:58

TimToady or maybe =<> is really ==@*ARGS, where prefix:<==> iterates a list of iterators, or a tree of iterators 19:18

TimToady just running the test
mncharity np, no hurry, just wondering the plan. 22:55
TimToady actually, half way through, so probably good enough to check in
(fix for circularity, not elsif)
ruoso TimToady, just a sanity check... so Foo::Bar.baz() will attempt to "coerce" the package to a dumb class that might even provide a method baz() even not being an actual class? 22:57
pugs_svn r22599 | lwall++ | [STD] fix circularity bug in unary and binary ops
r22599 | lwall++ | [viv] more progress in ~ delimiters through
TimToady something like that--might even degrade down to a P5ish dispatcher
mncharity apropos "reproduce the original exactly" (as a test of some parse tree's correctness), I note that I have learned fear of that concept. it always seems attractive, but since diffs often remain unusable until a sea of little nits get precisely dealt with, my attempts in that direction often converge too slowly to succeed. 22:58
TimToady depends on how you define "succeed" 22:59
and on how stubborn you are... :)
mncharity lol
ruoso TimToady, hmmm... that's actually a very sane option... a class-less package when coerced to a class returns a class that has a p5-like dispatcher as HOW
TimToady I know that's the only thing that worked for MAD
mncharity re (fix for circularity, not elsif), ah, oh, drat. ;) 23:00
TimToady the elsif problem is a little hairier, something to do with trying to bind a quantified parenthesis maybe
anyway, it's probably putting the $<elsif> binding inside the parens and then throwing it all away 23:02
mncharity re MAD, ah. yeah. So I guess my observation is "the path can be unexpectedly expensive".
given MAD, you know this.
TimToady some kinds of success can only be bought for "expensive"
and in that case it was something I had to pay for my earlier transgressions :) 23:03
mncharity re circularity patch, I confirm my loops have gone away. happiness. 23:05
