I take it you've seen Coro for Perl 5 ?
That's a very well developed system, having locks, support for async IO handles, etc 01:20
Of course the way Coro works is a little ... scary ;)

TimToady mugwump: mostly we won't be using async {...} or locks, I hope
lambdabot TimToady: You have 1 new message. '/msg lambdabot @messages' to read it.
TimToady most of the threading will be done by gather/take, lazy lists, and ==> operators 01:43
and most of the (non)-locking will be handled by STM
using contend/maybe/defer 01:44
mugwump I use it for threading 01:45
eg, in a network server 01:46
it means I don't have to worry about locking
yet, still everything is shared
TimToady which "it" do you mean? 01:50
STM?
nothingmuch ruoso: a nice idea is to use journalling 02:00
for the debugger, that is
an append only journal of Everythingā„¢ would make a nice omniscient debugger possible (since it's appendable it should be reflected from the runtime too, as long as it's own events are filtered at the very end to prevent infinite looping) 02:01
since it's only appendable that is
s/it's/its/ in the second instance
mugwump sorry, back 02:07
I use coroutines for writing network servers
I think it has advantages over ruby-esqye "green threads" in simplicity - you know that if a block of code has no preemption points it can't be interrupted 02:09

mncharity TimToady: STD.pm, line 2863: $here.expect_term() and similar elsewhere, but $here appears to get its value from expect_term() and similar. But expect_term is a token in the grammar Perl. /me puzzled. what am I missing? 14:48
expect_term looks to have type Match, or perhaps some class does PrecOp, or whatever 'make' is? 14:49
14:49 Andy_ joined
pmurias mncharity: why does a method in kp6-ruby return a closure which does the actual work? 14:51
pugs_svn r19864 | putter++ | [misc/red_STD] started work on operators. 14:54
mncharity pmurias: running the zero-ary method is actually name resolution. foo.whaterver works both when foo is a lexical var, and when it's a method (serving as a package/class var). 14:57
the thing it returns is the actual method (currently a closure, perhaps should be some Container instance ("Routine"?), perhaps with a Method or some such within). 14:58
pmurias is searching his copy of Programming Ruby 14:59
mncharity it's basically a hack to be able to emit code for variables without having to do a non-local ast check on what kind of variable it is. 15:00
err, the Container, Routine, and Method, were all intended as p6 classes. (well, ruby has Method too - might have to work around that:/ ) 15:01
15:03 Andy_ left
mncharity class A { sub f($n){$n+3} sub g(){ say f(1); { my sub f($n){$n-1}; f(3) } } becomes 15:04
15:04 rindolf joined
mncharity class A; def f;->(s_n){s_n+3};end; def g;->(){ say f.(1); ->(f){ f = ->(s_n){s_n-1}; f.(3) }.(nil) }; end 15:06
key thing is, the f.(1) and f.(3) have the same form, despite one being a class-scope and one being lexical. 15:07
which saves having to grovel over the ast to figure out what they are at compiletime. if you did that, then you wouldn't care.
you could emit the two cases differently. 15:08
pmurias mncharity: i see
mncharity hmm, actually the instances of f and g would really be c_f and c_g (for &f and &g, just as s_n is $n) 15:09
pmurias mncharity: our can be also view as declaring an lexical alias to a package variable 15:10
mncharity the ->(f){...}.(nil) is just introducing f as a lexical variable, with nil its initialization. for scalars, it would be ->(s_whatever){...}.(Scalar.new) 15:11
->(s_foo,a_bar,h_hee){...}.(Scalar.new,ArrayContainer.new,HashContainer.new) 15:12
{my($s,@a,%h; ...} 15:13
err, no, {my($foo,@bar,%hee; ...}
pmurias mncharity: i understand
mncharity stops rambling 15:14

pmurias mncharity: will red_STD be purely hand written? 15:20
15:20 cathyal left 15:22 cathyal joined
mncharity I suspect so. I'm currently viewing it as an experiment to see if "you can implement a p6 parser by just writing method code, with a bit of regex glue hand blended" works out. if it does, then the right thing may be 15:24
for someone to do a p5 version, for TimToady to hack on (potentially much faster and easier and non-buggy compared to pugs) as the grammar gets debugged, with STD.pm thus freed to be simply a "needn't work on pugs" spec. 15:25
even if the p5 version is cruftier than the p6, the edit-test (vs edit-cheat-metholate-pugs-test) cycle is soo much tighter and less landmined, that it could be an easier place to work until say parsing of t/ happens. 15:28
although it's hard to tell if you have a valid parse unless you run it 15:29
s/run it/compile+emit+run+test it/
pmurias i wander if most of the none fancy rules can be translated mechanicly (see KindaPerl6/Emit/Perl5Regex) 15:30
mncharity no doubt. one could perhaps adapt metholate. I'm still at the point of only attempting "42+1", a single flavor of literal, plus infix, just to see if I can figure out the operator precedence parser implementation. 15:34
15:35 cathyal left
mncharity though hand written ruby also has the potential to be much more concise than STD.pm, which decided not to use macros to simplify bootstrap. so it has appeal just to be able to see and understand the grammar in just a few hundred lines of code (vs a few thousand). 15:36
maybe. 15:37
15:37 cathyal joined
mncharity ok, I don't buy that "lots and lots more concise" argument. some things are 10x compression, but it's atypical. just happens to be what I was working on most recently 15:40
moritz_ diakopter: now I'm around ;)
mncharity brunch & 15:47
re translate, also, it seems there is a great deal of regex complexity (which one would thus have to examine manually anyway), and simple repetition (which it would be nice to abstract over). I did a transliterator hack for the EXPR code, but it's lossy enough I suspect hand syncing may be easier than continued use. 15:56

TimToady mncharity: at the method level (not at the rule/token level) the return values and the "self" are the current match continuation, which is proxying for both the current grammar and the current match object 16:44
it might well be that we need an explicit .extract_match to get the actual Match out of the continuation 16:45
(when implementing in something other than p6) 16:46
especially since the match data might not actually be stored in a hash yet, but scattered through a list of recent continuations 16:49
in short $here represents the complete state of the current match, including both current language and current results 16:52
16:54 jjore joined
TimToady there's also some monkey business going on about collecting all the old match data into the current reduction, which EXPR probably neglects to do yet 17:01
actually, that method is currently called .matchify, but I kept running into pugs bugs trying to collect match info, alas 17:06
.matchify is defined in Cursor.pm 17:07
note also that metholate can already emit non-backtracking code without gather/take; except that pugs doens't implement andthen or allow me to work around its absence 17:10

Daenyth I installed pugs a while back, before my distro had a package for it. I was wondering if there is a specific method for uninstalling it, as I'd like to install the packaged version 17:59
I can always --force it, but I wasn't sure if that had the potential to break things
moritz_ the Makefile has an 'uninstall' target 18:00
don't sure if it works, though
Daenyth mm, worth trying though
I didn't notice it in the readme
moritz_ found it by grep'ping Makefile
Daenyth heh 18:01
from make uninstall "uninstall is unsafe and deprecated" 18:05

hmm, I thought "a grammar instance captures the state of a search". guess not? ok, it looks like there are: Grammar, Cursor, Match, MatchContinuation. where MatchContinuation is a combination of Grammar and Cursor, and pretends to be a Match? 19:21
rhr_ ruoso: all tests pass on debian etch x86-64. solaris sparc 2.9 fails because I don't have complex.h (probably something I haven't installed) 19:23
mncharity Grammars have rules/etc... but no methods? the methods are all on the MC... which gets them via proxy from the Grammar? ok, my brain hurts. time to reread an Snn. 19:25
wolverian diagrams are good, though they don't answer the why
