gaal @tell Limbic~Region Data and Typeable are two datatypes used in haskell reflection, yes; Data is the one allowing generic folds. So for example, to implement the function that looks at a block like { $^a cmp $^b } and infers the set of placeholder variables are {$^a, $^b}, you basically need to write only a function that works on variables, and the generics stuff will sift through a possibly very complex AST node and find those, applying your functi 05:38
lambdabot Consider it noted.
gaal @tell Limbic~Region both you can get default implementations of both typeclasses from GHC, but Typeable's defaults are more likely to DTRT. 05:39
lambdabot Consider it noted.
gaal @tell lumi regarding Hs<=>pugs val bridge, see class (Show a, Typeable a, Ord a) => Boxable at Pugs.Class:36 and various instances from there, eg instance (Show a, Typeable a, Ord a) => Boxable (Maybe a). No Data required. 05:43

lichtkind: sounds even better
lichtkind but you cant use it inside perl5? 09:52
moritz lichtkind: it says "This is a regular expression/rules/grammar engine/parser designed to 09:53

lichtkind yeah but re::Engine is normaly a perl5 plugin 09:54
so i thopught re::engine::PGE is for the use in perl

moritz but what's the reverse for? 11:50
it currently reverses only a scalar

lambdabot tinyurl.com/yrp267 11:51
masak (but for different reasons)
11:51 Debolaz2 is now known as Debolaz
ayrnieu masak - well, for the same reason, but of course the semantics differ. 11:51
masak ayrnieu: as I understand it, in Haskell a string is a list
while in Perl, reverse does one thing for scalars and another for arrays 11:52
ayrnieu masak - yes, that would be part of the 'semantics' that differ. The reason is still the same.
masak ayrnieu: ok, granted :)
ayrnieu but OK, I'll accept { reverse [*] 1..4 } as a nice golf of that Haskell :-) 11:53
It could be better with a take 4 $ [1..] ; how is that in perl6? In Perl5, that specifically is easy enough to simulate with a tied array. 11:57

avar wrap Pugs::Compiler::Rule so you can do 13:03
if ("boobs" =~ /\$<x> = (b[oo|w]bs)/) {
say $&->{x}; # implemented
say $+{x}; # plan on it

all the re::engine:: stuff swaps out perl5 regexes for something else

obra We're looking for a new perl6 summarizer. Would anyone here be interested in the fame and fortune that comes with being the person to put a public face on all the work that goes on on Perl 6 each week? 15:31

obra smacks particle
15:32 buetow joined
[particle] has ann stopped for good? 15:32
obra ann's finding herself without enough time to do as good a job as she feels the job deserves 15:33
She's going to hang around for a bit to help with an orderly transition.
[particle] you know, i was wondering if there was a way a wiki or obby could allow multiple folks to act as summarizer 15:34
i call it, "cooperation"
obra it'd certainly be interesting
nothingmuch: want to hack on your tools more to make collaborative summarization easyier?
[particle] i was thinking about how spreading out release manager role for parrot has improved things, and thought the summarys could benefit 15:35
obra sure
it makes lots of sense 15:36
15:36 bonesss is now known as bones`almoco
obra "With enough hands, all work is shallow" 15:36
gaal kudra++ # great job when she did have time 15:38
[particle] indeed
lichtkind obra i would contribute but defeinitvly have the time to do it alone
[particle] i read every post, and i still find the summaries quite valuable 15:39
Alias__ obra! 15:40
You are totally the person I need to talk to right now
use.perl.org/~Alias/journal/32762
obra Alias__: how can I help?
[particle] wanted to talk to Alias__, but can't remember why
Alias__ Read that, then talk to me about commit bit
lambdabot Title: Journal of Alias (5735)
obra ok. setting up commitbit shouldn't take much work. sorry to hear about your repostorty. have you lost data? 15:41
masak pmurias: ah, now that you mention it, yes
so it's not really an error 15:42
Alias__ obra: Yeah :(
obra: The actual CPAN code is all intact, but I'm still patching together some commercial stuff
I mean, I have enough checkouts spread around they are ok, but I really don't want to lose the history
obra ok. was gonna say. I have a currentish mirror of the cpan code.
...this is where having svk can be a lifesaver ;) 15:43
Alias__ I'm extra careful to always have 4-5 semi-current checkouts
And fairly irregular proper backups
Or should that be fairly regular irregular backups :)
gaal unfairly regular backups? 15:48
Alias__ heh 15:49
Fortunately, MOST of the commercial code moved to DreamHost subversion, since for them having plain text passwords to edit doesn't hurt 15:50
For the CPAN repo though, it demands the automated account management stuff
ew 15:54
One thing I might have lost though, is the master for my codegen system
in fact, I haven't found an intact current checkout yet either 15:55
managed to save the database thank god
avar 15:34:07 <[particle]> you know, i was wondering if there was a way a wiki or obby could allow multiple folks to act as summarizer 16:01
I belive svn should be used for this
host it in the pugs repos?:)
obra avar: yes, though tools may help a lot to prevent duplicated work
16:01 fglock joined
avar *nod* 16:02
obra and we need someone to run the show 16:04
Are you interested in trying to speakhead ?
"spearhead"
Alias__ I prefer the term "spadehead" 16:10
Because it means you're the one down in the shit doing something useful before anyone else realises there's actually something happening
And then of course, while others are pouring the concrete, you sit back and lap up the applause :)

it is certainly "different", but not so much bizarre 18:16
or do you consider postscript bizarre as well?
18:16 vel joined, weinig is now known as weinig|bbl
broquaint I would say ColorForth qualifies as bizarre. 18:19
allbery_b googles and finds himself agreeing 18:20

broquaint That's the ticket.

broquaint Ah no, 5color3Forth it should be according to en.wikipedia.org/wiki/Colorforth 18:26
broquaint gives up
SamB hmm, is colorforth one of the distinguished few languages with multiple sourceplanes? 18:27
broquaint Looks like it.
I imagine it's only a small macro away in perl6 ... 18:28
18:31 aalaa joined
SamB supposes the sourcefiles are probably not actually stored in multiple planes 18:32
broquaint Doesn't look like it, no.
SamB but that was just a PC joke anyway ;-) 18:33

SamB hmm. 18:34
SamB thinks it may have been an incorrect PC joke
18:34 aalaa left 18:37 polettix is now known as torquemada
moritz hey, we could color-code different contexts in p6 source code 18:37

TimToady 18:45
tene use Color; class Foo { has $5private; has $10public; has $11publicisrw;
TimToady 's mind is obviously blank...
but i do kinda like the context coloring idea 18:47
especially since with p6 it turns into lazy vs eager coloring 18:48
broquaint If Perl 6 were a colour what colour what it be?
allbery_b octarine :)
tene broquaint: it changes based on what packages you use. 18:49
Alias__ allbery_b, maybe bluer than that though... octamarine? :) 18:50
moritz wonders how hard it would be to teach the vim perl6 syntax file to use different background colors for different contexts 18:51
TimToady I'm sure gaal would say Perl 5 is tan and Perl 6 is brown.
tene Why would gaal say that? 18:52
TimToady because brown is very mĆøĆøse
tene Ahh. 18:53
[particle] i think perl6 would be grue
grue is the new bleen, you know. 18:54
TimToady would you rather have a cold grue or a cold bleen?

 18:56

well, actually, some of 'em might think it's pretty shweet. 18:57

pmurias how does one write colorForth with a normal editor? 19:07
broquaint I think it can only be done within color 5color3Forth1 presently. 19:10
s/color //
SamB you could translate normalish forth, I think... 19:11
TimToady colorspace as syntax is just about as bad as whitespace as syntax... 19:13
broquaint Possibly a little unfair on the colour blind as well. 19:14
pmurias and the ascii shackled 19:17
SamB TimToady: I'd say it is worse
since it (a) requires editor support and (b) is probably not easy to type 19:18
pmurias (c) it is more expensive to print 19:21
gaal ~/~ given $moose { when :house<7> {...} } ~/~ 19:22

19:39 yuteh joined 19:47 geoffb joined 19:49 bonesss joined
geoffb BTW, as I recall part of the reason for colorForth (aside from pushing yet more CPU work in the runtime -> compiler -> editor direction) is to get as much conceptually on the screen at once, when limited by Chuck's low vision. Entire enlarged screen was 16 x 16 characters or some such, and he needed to fit a maximum amount of semantics within his editor window 19:53
