moritz Radvendii: strings are value types, so there's no difference between "the same string" and "references to the the same string"
shinobicl_ that's the error i'm having
i can't overload !== for a specific datatype. It complains about the !== needing "Numeric" 01:57
Radvendii no... if you use &[!==]($s1, $s2) as the function call it works. i think it's not parsing !== as the operator you defined 01:58
moritz it has to do with !== normally being a meta operator
shinobicl_ ohh, i see
Radvendii rakudo: our multi infix:<!==>(Str $s1, Str $s2) { return ($s1 ne $s2); }; say &[!==]("aaa", "bbb"); 01:59
shinobicl_ and === is a metaoperator too?

TimToady LTM failure for rakudo, methinks
mind, it's bad style to override metaoperators
shinobicl_ i din't know it was a metaoperator, my fault 02:21
moritz only mentioned it half an hour ago
dalek : 53ff291 | moritz++ | misc/perl6advent-2011/topic-brainstorming:
[advent] clean up topic list a bit
 02:22
shinobicl_ moritz: yes i remember :), i didn't know before that.... but is === a metaoperator too? 02:23
TimToady no
and it's only the ! that is the meta
it's ordinarly applied to == when you say !==
in += the = is a metaoperator 02:24
in X=> it's the X
shinobicl_ i thought that, if "==" is the opposite of "!=", then the opposite of "===" should be "!=="
TimToady != is just an alias to !== 02:25
shinobicl_ i fact i din't know it existed before trying to overload it
TimToady metaops don't replace characters like that though
there are currently 8 metaoperators, described in perlcabal.org/syn/S03.html#Meta_operators 02:26
02:27 orafu left
shinobicl_ "To avoid visual confusion with the !! operator, you may not modify any operator already beginning with !." 02:28
i'll use eq and ne then :)
TimToady that's what they're there for 02:29
like !=, ne is just an alias for !eq

pat_js if I have a regex like /<foo>* |<bar>/ in a grammar, how can I access them in a Actions-object? 03:32
with them I refer to $<foo> and $<bar>
oh my regex is not the one I'm asking for, it's more like /[<foo>|<bar>]*/ 03:33
03:34 s1n2 joined, s1n left 03:35 shinobicl_ joined
TimToady the bits should still show up in $<foo> and $<bar> 03:36
if you'd used () instead of [], you'd need $0<foo> instead 03:37
pat_js and the order?
japhb moritz, it looks like you pushed a bump to NQP_REVISION in rakudo 66edf0b6eb , but didn't push nqp?
03:37 molaf joined 03:38 jimmy1980 left
TimToady the subparts will be in the order matched, but you can't tell the relative order between the two lists unless you look at match positions 03:38
actually, if you'd used ()*, then $0[*] would be the order, and each of those would contain either foo or bar 03:39
often if you're starting to use $0, it means you really need a named subrule though 03:40
so you'd match <foobar>*, and foobar would match foo or bar
the standard grammar uses very few numbered captures 03:41
pat_js I don't think that will work, because <foo> is, in my case a proto token and <bar> is a recursive call
TimToady I meant <foobar>* would match <foo> or <bar>, so it isn't bothered by proto or recursion 03:45
03:45 jimmy1980 joined
TimToady that's no different from (<foo>|<bar>)*, except with a named rule 03:45

TimToady from the outside a named rule is simply that; it's invisible to the caller whether it's calling a proto, or something recursive
shinobicl_ perl6: multi infix:<eq>(Int $n1, Int $n2) { return ($n1.log10.floor == $n2.log10.floor); }; say (1 eq 9) ?? "Same" !! "Distinct"; say (1 eq 11) ?? "Same" !! "Distinct"; 03:48

PerlJam I'm refactoring ff and adding the fff variants. Does this look like a reasonable implementation? gist.github.com/1443400 16:17
(secondly to that, when I compiled it just now and attempted to test it, I keep getting complaints: Required named parameter 'x-left' not passed So, I think I might be doing something wrong (or there's a bug)) 16:18
jnthn You can't factor out callerid like that. 16:19
It'll bet the location of the infix.
*get
And not of the thing that called it.
PerlJam I figured that :) I just haven't worked out how to fix it yet.
jnthn Doesn't fff need thunking? 16:20
PerlJam also, I'm guessing there's a problem just using calledid anyway if there are multiple ff in the same scope
jnthn ?
16:21 buubot_backup left
jnthn It's global state, per program position, no? 16:21
callerid gives you unique per bytecode location, not unique per scope..
PerlJam ah, then that's good.
TimToady it's still a hack--long term ff wants to be a macro that declares its own state 16:22
all it really needs is a text macro
PerlJam sure, I just wanted to see if I could get there without macros. 16:23
jnthn TimToady: yeahbut masak++ didn't get macros far enough just yet
TimToady also, it won't work right with cloned closures, I suspect
jnthn it's global state, no?
not unique per closure? 16:24

PerlJam It looks like he's confused that he never sees "process" output to the screen and so thinks wrap is never called. But wrap is called ... just on the $r inside the sub that immediately goes out of scope. 16:41

TimToady he's not assigning to it, he's just calling an object method that happens to be a mutator 16:46
so I doubt this routine can enforce anything on that level 16:47

Util felher: I just looked at that this morning. 20:18
perlcabal.org/syn/S04.html#The_gath...ent_prefix
if a gather lexically contains any take calls, it is marked as lexotic-only, and it will be invisible to a dynamic take.
If the gather contains no take lexically, it by definition cannot be the lexotic target of any take, so it can only harvest dynamic take calls.
felher yeah, that is really cute :) 20:19
Util I wanted to mix lexical and dynamic `take` within one `gather`.
To make it work, just define somthing like:
sub take-dynamic ($item) {take $item} 20:20
and use it in place of the lexical `take`
felher Util: yep, nice one :) 20:21
Util I did not actually try the code; I was just positing an example in my own notes.
dynamic `take` allows for smoother refactoring of complex list-building code. 20:22
