Ontolog There is yet another .sub 'split' method in Str.pir, this one does not have :multi in the method signature 06:35
06:36 BinGOs joined 06:37 BinGOs left
Ontolog should it be removed? i'm not even sure what it does 06:40
it just takes two strings, makes them into Perl6Str, and runs a.'split'(b)
Which 'split' method would it be running in this case?
could this cause a recursive call? 06:41

07:14 iblechbot joined
moritz_ Ontolog: then nopaste your patch 07:15
07:17 zamolxes left
Ontolog pasted to #parrot 07:19
however there is still another split method 07:20
that i am confused about
removing also seems to not affect the tests
moritz_ there's a sub form of split also 07:21
for split("delim", "longstring") 07:22
Ontolog isn't $string.split("delim") and split("delim", $string) the same? 07:23
also if you look at 350 .return a.'split'(b) of Str.pir 07:24
which 'split' method is being called here?
moritz_ it's the same in terms of semantics, but it needs to be declared separately
because you can't call a method as a sub
usually we can use the export mechanism, but that would translate to split(lonstring, delim), which is not what we want 07:26
weird stuff
Ontolog i see 07:29
so should all three forms of split be in any-str.pir then?
or should this one stay in Str.pir?
moritz_ I think it should also be moved... 07:31
rakudo_svn r31250 | moritz++ | [rakudo] move Str.split(Str) to any-str.pir, Ontolog++ 07:35
r31250 | moritz++ | Now Str.split(/regex/) works because the method is no longer masked.
r31250 | moritz++ | I still don't understand why it fails with :multi(_,'String') though
Ontolog hmm moving the non-method split causes compile to fail 07:36
07:39 jfredett joined
moritz_ yes 07:41
which is quite weird
I guess because it has no :multi
and then it's in the same namespace as the other subs with the same name
07:48 zamolxes joined 07:54 Alias_ joined 08:00 charsbar left

moritz_ aye
masak also, I agree with Andrei: "Please also implement :g for .subst :-)" 09:55
:)
moritz_ [X] Patches welcome 09:56
rakudo: say ['abcd'.split(/<before .>/)].perl 09:57
p6eval rakudo 31254: No output (you need to produce output to STDOUT) 09:58
moritz_ so it loops
masak shouldn't it? 09:59
moritz_ masak: no, it should bump along after each match, just like in perl 5, and split into characters (I hope so, at least) 10:00
masak ah. reasonable.
actually, what's the shortest way to write // in perl 6?
moritz_ /''/ 10:01
masak oki
moritz_ but if you want to split into characters, no need for a regex
rakudo: say ['abcd'.split('')].perl
p6eval rakudo 31254: OUTPUT[sh: ./parrot: No such file or directory␤]
masak oops :)
moritz_ it's 12:01, rebuild time ;)

masak speaking of errors: on www.november-wiki.org/cgi-bin/w?act...nt_changes how do I change "[no address given]" into some email address? 10:02
moritz_ takes a few minutes on that server, it's not the fastest
eternaleye Is there an operator which takes a List on the left and an Int on the right and returns a slice containing the list repeated Int times? 10:03
so <a b c d> OP 2 would return [a,b,c,d ; a,b,c,d]
moritz_ infix:<xx> 10:04
in slice context
(but no implementation does slice context yet)
eternaleye Ah, that's why it didn't work. It assumed array context, and nothing does slice context yet 10:05
Dang
(I tried it in seevral incaarntions on p6eval but it died every time)
moritz_ as a workaround you can use map {[@list]}, ^$x
eternaleye *several (cursed key-reordering bug
moritz_ rakudo: say ['abcd'.split('')].perl
p6eval rakudo 31254: OUTPUT[Parrot VM: Can't stat languages/perl6/perl6.pbc, code 2.␤main: Packfile loading failed␤]

masak moritz_: not quite there yet 10:12
I'll bump it up in priority, just for you
moritz_ masak: no need, I was just curious
masak I have this wild idea about honeypotting people so that they can edit everything and see their changes, but all they do is queued up for moderation 10:13
until they are approved, then everything goes in
moritz_ like the wikipedia did it?
masak they did? 10:14
moritz_ (at least the German did, I think)
masak and here I thought I had an original idea :)
they don't anymore?
moritz_ no 10:15
masak was it a bad idea? 10:16
masak is curious
moritz_ I think it discouraged contributions
and it expresses that you don't trust people 10:18
(which is generally not a bad idea on the internet, but people don't want to hear that anyway)
masak hm 10:19
makes sense
I guess it's one of those ideas that seems technologically cool, but that turns people off
10:26 alanhaggai joined 10:30 Bzek left, smg left
eternaleye masak: also, it doesn't scale well - it requires that mod_hours/editor_hours remain near-constant, meaning that either moderators must do nothing but mod, or more (possibly unreliable) moderators must be added 10:33
masak eternaleye: aye.
so, for a small-size wiki engine, what's common practice?
moritz_ don't worry about abuse until it becomes a problem 10:34
masak moritz_: hm. :/
I like thinking ahead...
also, I've had problems on my home wiki of this kind
they started after I began publishing addresses to it on mailing lists 10:35
and they are very real, and time-consuming once they've begun
masak hates wiki spammers

i don't know what all the is_deeply stuff is either :p
pmichaud moritz_: I think I may able to get an 'eqv' operator working this weekend, at least for lists.
afk, lunch. 16:11
16:16 ashleyb left 16:17 iblechbot joined 16:22 masak left 16:28 meppl joined
TimToady pmichaud: eqv on a hash could be optimized greatly over naive comparison of serializations 16:41
first of all, you can reject if the number of keys differs
it would also be relatively easy for the hash header to maintain an XOR of all hash values for existing keys 16:42
16:43 alanhaggai joined
TimToady and comparing those would give you an almost instantaneous rejection of hash equality most of the time 16:43
and for the situation where they are equal, you're just wanting to make sure that all keys in one are also in the other
and since the keys are identical, when the hash bucket layout is the same, you can just walk the buckets in parallel, and make sure each pair of buckets contains the same keys 16:45
and in general, for more complicated data structures, there's something to be said for checking all the components for easy falsifiability before checking any of them for trueness, if there is any way to compute such a traversal cheaply 16:50
or lazily 16:51
for immutable values a hash of the .perl of everything might be lazily cached the first time we use a value in an eqv 16:52
anyway, just some random premature optimizations :) 16:53
oh, wait, eqv requires the hash values to be eqv too, so a hash-wide key xor only tells you if the keys are unequal; you still have to walk the buckets for both keys and values if the keys hash equally 16:54

ruoso heh... although the above statement might look weird, it actually means that at the moment a generic lazy list is implemented, it can be used with map... 23:15
it's still missing the map in item context, which provides a flattened iteration, independent of the number of items returned in each iteration...
