01:14 Limbic_Region left
zev I'm looking at #58524, which references S04. S04 says that "=<>" is equivilent to "=$*ARGS". should that be "@*ARGS"? 01:15
pmichaud no, it's $*ARGS 01:16
@*ARGS is an array
lambdabot Unknown command, try @list
pmichaud $*ARGS is a magic filehandle iterator
zev I ask because misc.pir has the '=<>' sub calling 'prefix:=' with "get_hll_global '@ARGS'" as its argument 01:17
pmichaud yes, it's wrong. 01:18
(misc.pir, that is.)
zev then it should be get_hll_global '$*ARGS' ?
pmichaud it can be, if someone would write the code for '$*ARGS' :-) 01:19
(rakudo doesn't implement $*ARGS yet.)
01:19 hudnix_ joined 01:23 alc joined 01:24 ruoso left
zev so, it's supposed to be an iterator that iterates over either the command line arguments or standard in? 01:25
pmichaud over the files given by the command line arguments, yes.
zev what is the $*ARGS capture then? 01:26
pmichaud I don't understand.
zev (I'm looking at the table in S06 under 'Declaring a MAIN subroutine')
wolverian www.itu.dk/people/mir/typesafepatterns.pdf reminds me of some aspects of given/when 01:27
01:27 kisu_ joined
pmichaud $*ARGS as a capture (as described in S06) would be the command line arguments after they've been processed for option switches 01:28
I'm not sure that's intended to be the same $*ARGS described in S02/S04 01:29
so perhaps one or the other is a typo
if they are intended to be the same, then iterating over $*ARGS is what produces the successive opens of any filenames given in @*ARGS 01:30
01:30 alanhaggai left
zev how would it be different if they weren't the same $*ARGS? 01:30
01:31 kisu left
pmichaud I don't know. 01:31
we probably need a clarification from p6l
zev ok. I'll send mail
anyway, so $*ARGS should iterate over all the files specified on the command line followed by stdin 01:41
in terms of implementation, does it make sense for it to be an instance of a subclass of IOIterator? 01:42
01:43 alexn_org joined
zev or perhaps this is something that would be better implemented in Perl6 itself (to get anonymous subclasses) 01:44

TimToady qq and q have independent backslashing rules 01:50

TimToady for instance, the default is different for things that didn't need backslashing
01:52 azawawi_ joined
TimToady :b is the qq semantics, not sure what the parenthetical remark means 01:53
literal so q{\s\d\k} == '\f\b\g', while qq{\s\d\k} == 'fbg' ?
assuming \s, \d, \k are meaningless espace sequences 01:54

pmichaud TimToady: when we say that 'map' and 'for' are isomorphic, does that extend to things like NEXT/LAST/REDO closure traits? 02:25
TimToady seems reasonable 02:26
pmichaud is 'next' lexical like 'return' is lexical?
02:27 alexn_org left
pmichaud i.e., if I have for @list { ... my @b = map { next if ... }, @something } 02:27
then the "next" applies to the lexical for loop, and not the 'map' ?
TimToady why shouldn't it apply to the map? 02:28
pmichaud it certainly _can_, but afaik 'map' isn't a statement construct just yet 02:29
TimToady lemme stew about it over dinner.
pmichaud okay.
pmichaud had stew for dinner last night. 02:30

it seems you're doing a lot of work :) 11:22
pmurias the output from eval_pv disappears when stdin is redirected to a file
any ideas what causes this
?
ruoso you mean stdin fed from a file 11:24
or stdout redirected to a file
?
pmurias sorry stdout
ruoso it's probably because of buffering
pmurias ruoso: it's ok that i change the build system to scons? 11:25
ruoso conceptually, yes...
but i'm not being able to build it 11:26

12:10 alexn_org joined
ruoso pmurias, I think I'm going to work on sanitizing the interpreter usage according to lowdoc/03 12:10
actually, 02
so we can implement exception handling 12:11
pmurias doesn't 02 describe the current state? 12:12
btw it might make sense to merge has_next/next/eval into eval 12:16
ruoso pmurias, it describe how we already think it should be 12:35
but not every continuation has .back being set all the time
and none of them has .control and .catch
pmurias continuations should have a .clone method if we want to support continuations 12:36
ruoso that would be cool
pmurias the continuations we currently have are really coroutines
ruoso well... the definition for "continuation" is not that strict 12:37
but I see what you mean
it is still a continuation, even if it can only be invoked once
but at least mold can be cloned easily 12:38
pmurias got any solutions for making pcl valgrind clean? 12:41

pmurias ruoso: you want to drop the haskell dependency? 14:07
14:07 ejs left
ruoso well, we already depend on p5, if it's not too hard, it would be nice... 14:07
and it would have the advantage that it could only "require SMOP" when trying to exec 14:08
and thus avoiding the circularity between m0ld and libsmop 14:09
pmurias, we could even write the m0ld grammar in Perl 6 ;) 14:12
pmurias ruoso: how do you intend to run the Perl 6 grammar
?
ruoso the same way STD runs 14:14
pmurias it's a bit frail
i went that way with sm0p and it broke a couple of times 14:15
ruoso but I think Parse::RecDescent would be enough to parse m0ld

14:19 vixey joined
pmurias the circularity could be avoided even without a rewrite of the m0ld compiler 14:22

ruoso is it sane to assume that ReturnControlException is a prototype that is closed and final? 18:13
meaning that you can't subclass it, nor compose roles into it... 18:14
this would be important because it would mean we can make it as a native type in SMOP

@tell pmurias do you think we could have a "leave" operator in mold? This operator would call setr on the back with the given register and goto the back frame... 18:19

dwhipp That's an answer to the first "winter scipting games" challenge

dwhipp problem is, "X-X" does the full cross-product, not justhte diagonal halves
pmichaud please please please post (and explain) it somewhere. :-)
eric256 i was going to use a cross but couldn't decide what to do about matching itself, yours is good, albeit scary 18:42

then I count them
18:42 gbacon joined
eric256 i think he meant somwhere else ;) 18:42
dwhipp but I need to adjust the count to remove the diagonal and the repeats
eric256 hence the /2 right? 18:43
oh wait i get it, /2 is for both halves of the pair, -@.elems is for the pairs that are themselves
dwhipp - @a.elems gets rid of the diagonal
pmichaud yes, I meant post and explain somewhere else. So others can see the awesome beauty and power that is Perl 6. :-)
dwhipp Perhaps "beauty", yes. But to my mind it shows that the cross operator is too limited for true elegance 18:44
eric256 is there anyway to get all the elements in an array that arn't the current one? hmm @a(*..^$i^..*) ?

dwhipp this gives the correct result for hte "count number of cards that have subsequent partners" question 20:11
but we need the overall range to be "0 .. @a-2", not "0..@a-1" 20:12
so ^@a doesn't work as a range in this context
ruoso maybe 0 ..^ @a.last makes it clearer
0 ..^ @a.end actually 20:13
dwhipp is this an edge-case bug with junctional behavior -- or just a gotcha?
ruoso what do you mean?
dwhipp rakudo: 3 == any() 20:14

dwhipp rakudo: ?(3 == any())

20:15 alanhaggai_ joined
ruoso ah... but if you have @a[$x..$x], you're hitting the rakudobug 20:15
because it was supposed to return an empty list, but it's returning the entire lits
dwhipp OK, so once that's fixed the "(^@a).grep: {...}" should work. No need to figure out the exact range expression @a.end-1 20:17
eric256 could you just get the indexs that are not the current index?

eric256 the any doesn't match cause its returning 1 if there is 1 or more matches
you actualy want to count all the occurences of the same value after this one 20:21

eric256 i think so yes
thats two for me ;)
unobe is $_ the same as $k? 21:07
ah, no
eric256 .kv on an array returns the index and then the value so i put those in $k and $v 21:11
unobe right, and since $_ is in grep, it's not $k 21:12
I like the .kv usage 21:13
it's just the p +=
it's just the $p += part
eric256 yea i dunno what to do with that. could push them onto an array and sum it, but i'm not sure thats much of a win 21:15
