adu what does <x>: mean? 01:10
TimToady don't backtrack into it 01:11
phenny TimToady: 08 May 22:48Z <diakopter> tell TimToady try 3875928375982735.383854792874359827349682.floor on p6eval

adu TimToady: you've been soo helpful today :)
TimToady well, everyone here is that way because someone was helpful to them at some point 01:13
adu why is this not working? 02:03
"24" ~~ m{ \d ** 1..3 { +$0 < 256 or fail } }
TimToady put () around the capture 02:04
otherwise it doesn't get into $0
adu YEY thanks :) 02:05
that looks so much nicer on the eyes than [ \d | <[1..9]> \d | '1' \d \d | '2' <[0..4]> \d | '25' <[0..5]> ]
colomon or it could be +$/, instead of $0 ? 02:06
oh, no, never mind
TimToady and I'd write that <?{ $0 < 256 }> which tests a boolean expression more succinctly
adu ok
TimToady since it's not clear that 'or fail' is going to be the eventual backtrack trigger 02:07
colomon TimToady++
TimToady but <?{ ... }> will continue to work whatever
adu "257" ~~ m{ \d ** 1..3 <?{+$/ < 256}> }
YEY it fails :)
adu I've learned so much in one day 02:08
TimToady don't worry, you'll forget most of it by tomorrow. :)
sisar moritz++ # range bugfix 02:10
adu how do I use tokens and rules in matches/regexes? 02:16
TimToady wanting to usually means you should write a grammar instead, but there's some support for calling <Grammar::rule> I think 02:18
generally a grammar is invoked with .parse though
adu ok
TimToady we may revise our view of that as we get more experience 02:19
adu I'm having trouble loading the whole grammar
TimToady syntactically? 02:20
adu if I do use dreme::datum::Grammar then it says Cannot call 'trait_mod:<is>'; none of these signatures match...
I probably suck at writing grammars 02:21
TimToady well, it'd be nice if it told you the line number, but rakudo is a bit weak on that for run-time errors (and traits, though run at compile time, are basically run-time code) 02:22
adu the only "is" is at the top
grammar dreme::datum::Grammar is HLL::Grammar;
should I delete the HLL::Grammar when testing with perl6?
TimToady I don't know; is that from parrot somewhere?
adu yes, well I started with parrot's language template 02:23
TimToady it sounds like one of those bits of nqp that doesn't really translate to P6 02:24
but I've never done anything with HLL::Grammar
in theory, just declaring 'grammar' should give you whatever base classes are necessary for a normal grammar 02:25
adu hmm
ok, the "use" worked i think 02:26
now how do I access this "parse" method?
adu ok perlcabal.org/syn/S32/Rules.html says for the Grammar API, See Abstractions.pod 02:36
adu where is Abstractions.pod? 02:38
TimToady beats me; I've never seen that file before, despite my name being on it... 02:42
anyway, dinner &
oh, another thing you might try is running it under niecza, which has a different set of not-yet-implementeds than rakudo
bbl & 02:43
adu hmm 02:49
adu I keep getting Could not locate compile-time value for symbol dreme::datum::Grammar 03:05
how do I load a grammar? 03:06
adu what's the difference between require and import? 03:13
and need?
and use?
adu is so confused 03:39
diakopter hm 03:40
PerlJam adu: what about?
adu import, require, use, need 03:40
diakopter did you see S11? 03:41
adu I'm reading S11 right now
but I'm not sure if it applies
because they seem to be for packages and modules
and I'm trying to import a grammar
diakopter about a 1/3 of the way through it it explains what need/import/use do 03:42
and require
just to be certain, you're reading perlcabal.org/syn/S11.html ?
adu yes
so I do this: use dreme::datum::Grammar; 03:43
and perl6 says "Nil"
then: dreme::datum::Grammar::TOP
and perl6 says Could not find symbol 'dreme::datum::Grammar::&TOP'
PerlJam adu: what's the name of the file that contains dreme::datum::Grammar? 03:44
adu dreme/datum/Grammar.pm
diakopter omg I just typed that exact question
adu in the current dir
I can pastebin it
PerlJam adu: please do 03:45
adu: your grammar declaration needs to be grammar dreme::datum::Grammar { ... } too:q 03:46
adu pastebin.com/dukkRaqd
diakopter did you try the { } form 03:47
adu hmm nope
diakopter might be a bug that makes that necessary
adu it would be nice if S11 mentioned grammars too
diakopter agree 03:47
adu I'm still getting "Could not find symbol 'dreme::datum::Grammar::&TOP'" 03:49
diakopter can you pastebin the file that's using the grammar? 03:49
adu I'm not importing it from a file 03:49
I'm using rakudo's repl 03:50
diakopter ah
that has problems, I seem to recall
adu ok I put it in a file 03:51
pastebin.com/q55xnv6e 03:52
diakopter I don't know that TOP will be accessible like that
adu hmm ok 03:54
how do I parse the grammar then?

diakopter hmm
adu PerlJam: that gives me: "Could not find symbol 'dreme::datum::&Grammar'" 03:56
there must be something I'm missing about packages or importing 03:57
diakopter it worked ("broke") in my gist
maybe loading Grammars from another file doesn't work
it might not be implemented
PerlJam diakopter: it does work.
diakopter or spec'd, for that matter
oh
PerlJam ww might not be implemented though 03:58
diakopter adu: see my gist?
adu so you put it in the same file 03:59
PerlJam Hmm
adu that'll do for now
PerlJam adu: it works in separate files too, but it dies the same way as diakopter's gist 04:00
adu this is why I wanted to run it :)
so I could get feedback
PerlJam something weird is going on with <ww> 04:01

PerlJam you don't like newlines?
warp0x00 is that what that is
PerlJam ah, yes. that's a newline symbol
warp0x00 what font do i need for that
diakopter small N and L
depends on your platform
warp0x00 debian gnu/linux 6.0 04:31
so once various compilers pass all the tests 04:34
does that mean it its time to write more tests
adu I'm using gnu-unifont, and I can see NL just fine 04:35

inchok78 hello all 04:44
adu hello 04:45
inchok78 can u recommend webpages with stories of Perl 6 used for production work? 04:49
join #kubuntu
(boy am I rusty) 04:51
sisar is having fun and wasting time with ie.microsoft.com/testdrive/Graphic...chEffects/ 04:52
sorear inchok78: 'stories' isn't really how stuff gets done. 04:54
masak might havge something, but he won't be here for a few more hours
also, 'production' is a pretty nebulous concept 04:55
we once had a user in #mono come in asking if it was production ready... after much harassing, I got them to admit their goal: create a website able to serve equal or greater traffic load to Wikipedia 04:56
inchok78 ok... non-technical people trying to get a 30000 feet feeling for whether Perl 6 is able to be a player in a project BEFORE the programmers get involved...
this is about connecting a heart recording device to a remote database 04:57
diakopter I think a good definition of used in production is: used in business or large-scale personal activities
inchok78 forgive my ignorance and if my tone is not right, forgive that too
diakopter :)
there's lots of forgiveness around here
sorear inchok78: I'm not mad at you
inchok78 yeah. i used to do scripting in 5.8 or something, when the universe was young. now i do project for big research and haven't touched a proper programming lang. in 5 yrs 04:58
sorear Perl 5 and Perl 6 are being developed concurrently 04:59
sorear Perl 5 is still a lot faster and is less likely to break on you 04:59
inchok78 oh
(i used to keep tabs on pugs back in the day) 05:00
sorear for various regrettable reasons, Perl 6 did a lot of stalling back in the mid-2010s 05:01
diakopter inchok78: to get that 30000 feet feeling would be difficult at this point, I think.
inchok78 mmhhhh 05:02
sorear I'm the main developer of one of the currently active implementations and I have a lot of forest/trees problems, yeah 05:03
performance (broadly construed) of implmentations currently... in a word, inconsistantg
some things work compellingly better than Perl 5. other things will cause major slowdows. You don't get to know in advance 05:04
is this a project which requires certainty or high speed? if so, definitely stay away from 6
inchok78 got that. i will do my due diligence 05:05
inchok78 just for curiosity, what is the implementation you're working on? 05:05
diakopter niecza 05:06
diakopter github.com/sorear/niecza 05:06
inchok78 thanks... will look it up on the windows machine... this here kubuntu has no web access 05:07
sorear fwiw, niecza works fine on mono 05:08
oh, wait, if you haven't looked it up yet you must not be commenting on that 05:09
inchok78 my wife is a mono guru. i am not currently into programming but want to get back on soooo badly
sorear inchok78: I'm sorry I can't give a straight answer. I won't say "use Perl 6" because there are a zillion things that are still very much broken with it. I won't say "avoid it" because there are even more things that work fine. 05:10
inchok78 i guess that sums it up. looking niecza on the other computer, but pretty aware this is mostly to satisfy my curiosity at this point 05:11
sorear another note... popular perception of Perl 6 among programmers is still mostly at the "dismal failure" stage 05:13
diakopter and they're probably mostly right, by their definition of dismal failure. 05:14
inchok78 i clearly recall that was the feeling on reddit a few years ago, but then left that too (...)
sorear the community was in a sorry state 2-3 years ago, and sometimes information propagates amazingly slowly through the internet
adu I think perl6 definitely needs more tutorials 05:15
TimToady if success is eventually defined by not letting the bastards wear you down, we've gotten real good at that part of it :)
the tutorials could use work though :)
diakopter to amend my previous statement, I agree that there is also lots of false information believed. 05:17
adu YEY 05:20
pastebin.com/GJ3enmmw
0 to Scheme in less than a day! 05:21
diakopter anyone like/dislike my definition of used in production?
adu++ # most impressive
inchok78 may I say, usage of "production" differs slightly across segments of industry 05:22
in my case, since it involves clinical/medical/veterinarian, a production system is one that has been validated to comply with applicable laws and regulations and is used to produce (quack!) information that is to be delivered to a customer 05:23
TimToady production, in the case of a language, also implies more commitment to backward compatibility than you're likely to find yet in Perl 6 05:23
adu Go took that step recently 05:24
they released "Go 1"
inchok78 (even though you'd be surprised what crap can be validated by the naive organization)
TimToady yes, and we'll get there as soon as our implementations and specs/tests converge on each other
shinobicl hi,,, i'm finished a module for perl6. i dont think it's ready for the ecosystem, though. But i think is good enough for a beta version. 05:26
TimToady at that point we'll also provide the user the ability to freeze at a particular semantic version, even if emulated by something newer
shinobicl github.com/shinobi/p6/tree/master/...ayCalendar
adu diakopter: thanks
adu diakopter: I think "used in production" has more to do with risk than business or large-ness 05:27
diakopter I think you and TimToady are defining "production ready", which is different from what I was defining 05:28
adu like keeping 1 person's heart beating isn't large or busy, but the risk of railure is high 05:29
fail
diakopter that's definitely a business activity
adu i suppose
TimToady shinobicl_: \o/ 05:37
diakopter is still reading WorkdayCalendar.pm 05:38
shinobicl_ hi... had to switch computers...
i'm on a tablet now :(
diakopter ooo repeat-until

shinobicl_: which implementation(s) did you develop on?
shinobicl_ rakudo only
afaik niecza does not have Date yet 05:43

adu crap
diakopter I wish I knew enough to comment on how idiomatic it is

tadzik I'm at $work atm so I can't really give it a try though :( 14:25
kboga np, also, the pack.t tests seem to require Buf to have a contents method, couldn't find it in the spec's tho... 14:26
tadzik you should probably ask masak++ about it
masak yeah, probably. 14:28
masak claims he knows a bunch about pack/unpack and how to implement them in Perl 6.
myself, I think he's just a poser. :P 14:29
kboga didn't he implement that initial version I blatantly copy pasted? :) 14:29
masak probably. 14:30
I hear he's tried to port the Perl 5 tests to Perl 6 as well, but nothing concrete's even come of that.

jnthn ah, ok
Which I think moritz++ is on top of already 14:40
masak kboga: yes, that's a good summary. Perl 6 is more type-constrained in this area than Perl 5. so it needs to disallow certain combinations.
kboga: that said, we still want to make easy things easy, so it's a balance for sure. one we haven't found yet. 14:41

colomon actually, by current spec most of the Rat tests in stringify.t are wrong. 14:45
kboga I'm curious about how compact structs will mix with pack & unpack. Somehow it reminds me of Convert::Binary::C. 14:46
gfldex S03 says: "Any class composing the Pattern role may choose to provide a single ACCEPTS method to handle everything, which corresponds to those pattern types that have only one entry with an Any on the left above." 14:47
gfldex yet i can't find any role named Pattern, is that NYI? 14:47
jnthn Wow, I didn't even know it existed... 14:52
jnthn wonders if there's any spectests for it 14:53
kboga: Compact structs should go fairly nicely with it.
Well, they probably are an alternative I guess...
Taking a Buf and using the data in it to populate the compact struct. 14:54
Though, we could actually implement the data extraction from Buf using unpack I guess.
jnthn You get into all kinds of fun questions about what "compact" implies 14:57
Like, does it mean "pack it as tightly as you can" or does it mean "pack it as tightly as the usual way to back a struct on the underlying architecture would allow"
s/back/pack/ 14:58

this is quickly becoming a rathole
TimToady might be awake enough to discuss rats 16:23
phenny TimToady: 11:08Z <colomon> tell TimToady Just looking over quote:mm in Niecza and std, wondering if there was a copy and paste mistake. Seems to me that maybe quote:mm is implemented the way quote:ms should have been (it's not there at all) and quote:mm should also have .tweak(:mm) ?
TimToady: 11:12Z <colomon> tell TimToady errr... or does quote:mm not make any sense at all? "The :mm (or :samemark) variant may be used on a substitution...."
TimToady: 14:24Z <colomon> tell TimToady We need to talk about Rat.perl and Rat.Str....
colomon TimToady: I think I sorted out the mm/ms thing -- when mm// became ms//, STD.pm6 was never updated to match. (I have now done so.) 16:24
TimToady I saw that
TimToady wonders if we should allow <1=digit> and such
and maybe simplify <~~1> to <1>
colomon well, I was just trying it to get $<1 2 3> to make sense
colomon as for Rats -- my big question is, are we really serious about "The .perl method will produce a decimal number if the denominator is a power of 10, or normalizable to a power of 10 (that is, having factors of only 2 and 5 (and -1)). Otherwise it will normalize and return a rational literal of the form -47/3." ? 16:25
(and that should be <-47/3>, right?)
the spec is not at all consistent on this.
TimToady
.oO(now they want the specs to be *consistent*, sheesh...)
 16:26
colomon I'm working on implementing a new Rat -> Str conversion that follows what the spec actually says. :)
TimToady well, the spec might be wrong :) 16:27
it's happened once or twice
colomon the spec certainly is wrong somewhere here... it's 100% definitely not consistent

jnthn masak: Yes.
masak: It knows what it is, and it knows that it doesn't know how to do it :) 16:32
TimToady tadzik: I seriously doubt that bit of the translator is implemented
colomon TimToady: personally I like essence (as I take it) of the stated Rat rules; I just want to clean up the rest of the spec bits to match.
TimToady or do you mean translate everything around the tests, but leave the formats the same?
tadzik TimToady: possible; just a random thought 16:33
masak jnthn: I think this used to work, in b, no?
jnthn masak: "work"
PerlJam TimToady: does <!~~1> exist? If so, what would that become if <~~1> became <1>?
jnthn masak: Also, the implementation of it was horrible.
masak oki 16:34
tadzik phenny: tell sisar yes, you need to recompile ALL THE THINGS
phenny tadzik: I'll pass that on when sisar is around.
TimToady reducing <~~1> to <1> doesn't help get rid of <~~foo> anyway, since <foo> means something different
but <1=foo> is easier to read than $1=<foo>
jnthn It's probably more consistent to leave it as <~~1>
<1=foo> wfm though
TimToady as for <!...>, that's really a sort of metaoperator, and recursively calls <...> 16:35

moritz_ it's easy to search for if you happen to remember the title :-)
TimToady colomon: anyway, I've taken a dislike to the part of the spec that stringifies Rat via Num, which violates POLS by throwing away precision above the decimal point for largish numbers 16:55
masak well, I tried ddg'ing before asking.
moritz_: used your post in a reply here: www.reddit.com/r/perl/comments/tdq8...on/c4lzli7 16:56
moritz_ masak: I ddg'ed too. But I remembered the exact title :-)
masak aye, that helps. 16:57
TimToady I think a Rat.Str should always produce the integer part exactly, and how much of the fraction is negotiable
TimToady of course, my stupid little routine doesn't handle :base, nor did it bother to round the last digit 16:58
it was more a proof of concept
and running 1/3 all the way out to 50 digits could be construed as antisocial :) 16:59
fglock p5-to-p6 would emit unmaintainable code that goes through an emulation layer, that's not good for translating tests (this is not a perlito specific problem) 17:10
masak nod. 17:15
though for narrower use cases, it's still possible to get something useful out the other end.
TimToady I could see a use for a translator that does the easy stuff, but just marks the hard stuff rather than trying to emulate it 17:16
fglock hmm - that sounds... easy 17:19

colomon TimToady: interesting, your approach to this was very different than mine...
TimToady if yours is faster and produces the same results, go for it 20:05
I was more prototyping policy than anything else
TimToady the important part is to leave the integer part out of the precision calculation entirely 20:07
the rest is negotiable, but 6 digits for repeaters seems to fit with the %f format default 20:08
and gets all the repeating digits for 1/7 20:09
the important thing is that it never loses precision for denominators that are sufficiently decimal 20:10
I *think* one digit of slop is enough to guarantee that, but I have no proof... 20:11
anyway, the gist above has a rudimentary test of that out past the six digit minimum 20:12
and seems to work for those two numbers anyway
there's probably a faster way to take the log10 of the number than look at the length of the string conversion 20:13
jnthn figgers out what's up in #112624 20:14
colomon well, my approach was very different, as I was only trying to get all the decimal digits for cases that were supposed to be exact according to the existing spec.
jnthn Not sure I've got the energy to fix it tonight, though.
jnthn leaves it for tomorrow
TimToady colomon: well, turns out you can get that for "free" with this approach 20:15
jnthn moritz: I think rt.perl.org/rt3/Ticket/Display.html?id=112586 is taken care of now? 20:17
TimToady it's also probably faster to compare the number with 1_000_000 than to stringify it and max with 6 20:18
so that line would be something more like: 20:19
my $want = $r.denominator < 1_000_000 ?? 6 !! $r.denominator.Str.chars + 1;
or maybe that wants to be 100_000, since we should fudge a large 6-digit number up to 7 20:20
okay, gist revised again 20:23

shinobicl_ hi all.... is there a way to get a "review" to a perl6 module i did, so it gets published in modules.perl6.org? 20:24
jnthn shinobicl_: Does it already have a META.info? 20:28
shinobicl_ yes
github.com/shinobi/p6/tree/master/...ayCalendar
jnthn Then it just needs to end up in github.com/perl6/ecosystem/blob/ma.../META.list
shinobicl_ i just have a doubt about what to put exactly on the source-url field 20:29
dalek osystem: 17179c6 | jonathan++ | META.list:
Add Date:WorkdayCalendar to ecosystem; shinobicl++.
 20:30
jnthn shinobicl_: Put the URL of the git repo: git://github.com/shinobi/p6.git 20:31
shinobicl_ thanks!
ok
jnthn oh, wait...
You have one repo for all Perl 6 stuff
I think it's meant to be one per module
shinobicl_ oh i see
jnthn yeah...otherwise I suspect panda won't know to look inside that "p6" directory 20:32
jnthn I guess easiest solution is that GitHub lets you rename a repo, and then just do a commit that moves stuff out of the directoy into top-level 20:33
shinobicl_ i'll create a new one then 20:33
jnthn ah, ok 20:34
jnthn Let me know when you're done and I can update the ecosystem list again. 20:34
TimToady I think there's a bug in r2s for values that round up .9999 and such; it won't carry back to the integer part 21:01
shinobicl ahh... another thing..... i'm using "Date" as the namespace for WorkdayCalendar 21:06
shinobicl should i use this namespace or "DateTime" instead? 21:06
dalek blets: fab2926 | (Herbert Breunung)++ | docs/_nav- (2 files):
repair spacing in header and footer
 21:07
shinobicl i ask because there is a module listed as DateTime::Utils 21:11
moritz if you work with dates, Date. If you work with dates and times, DateTime 21:13
TimToady well, maybe it's a "can't happen" 21:16
TimToady I can't come up with a case that forces it to carry back to the integer part 21:26
sergot_ 'night o/ 21:27
spider-mario in case you’re interested and you understand french, I’ve had a little discussion regarding the readability of a Perl 6 code vs. its Common Lisp equivalent 21:28
progmod.org/forum/sujet/333/message/3949/
(the Lisper is Zeta)
[Coke] huh chrome offers to translate, says it has, but it's allf rench to me.
TimToady wonders if dalek will report the spec change I just pushed for Rat.Str
[Coke] TimToady++ # there you go 21:28
TimToady oh, I don't care about the karma, I just wanted people to see it :)
colomon TimToady: just got a notification for it in my e-mail. :) 21:28
colomon TimToady: why did you change it there and not in S02? 21:28
TimToady lazy :)
colomon BTW, S02 also seems to say that every number with a decimal point should either become a Rat or a RatStr. Does that seem likely to stay to you? 21:28
dalek ecs: e1cc4fa | larry++ | S02-bits.pod:
also tweak Rat.Str description here for colomon++
 21:32
TimToady where does it say that?
colomon TimToady: search for "Allomorphic Rats"
lichtkind TimToady: grrrreetings
what is actuall U ?
some sort of undefined?
TimToady I do still think that .perl should try for decimal notation if it works. 21:33
colomon TimToady: agreed.
TimToady it means it's not a real object
colomon TimToady: if it is exact
jnthn lichtkind: As in, Any:U style things?
lichtkind: It means it's a type object.
Equivalent to checking that .DEFINITE is False 21:34
colomon TimToady: should Rat.perl be one of either N.M or <N/M> ?
TimToady yeah 21:35
lichtkind jnthn: i dunno i just saw moritz to use the U method
TimToady yes, only if it's exact do you get N.M
lichtkind so its true if its a type object?
jnthn lichtkind: Method? Oh...then I dunno :) 21:36
lichtkind jnthn: what is this Any:Uß
jnthn lichtkind: It's a type modifier. 21:38
jnthn r: class A { }; sub foo(A) { say "ok" }; foo(A.new); foo(A); 21:38
p6eval rakudo 9a4981: OUTPUT«ok␤ok␤»
TimToady colomon: it doesn't say 'any number with a decimal', it says 'any rational literal'
jnthn r: class A { }; sub foo(A:U) { say "ok" }; foo(A.new); foo(A);
p6eval rakudo 9a4981: OUTPUT«Parameter '' requires a type object, but an object instance was passed␤ in sub foo at /tmp/V5K06_21PO:1␤ in block <anon> at /tmp/V5K06_21PO:1␤␤»

TimToady but it does seem that pi.perl should probably print 3.141592653589793238 rather than the fractional form 21:39
TimToady or maybe it should return the .Str form 21:39
jnthn Uh...pi should be a Num, no?
colomon jnthn: that's what I'm asking.
jnthn rakudo: say pi.Num
p6eval rakudo 9a4981: OUTPUT«3.14159265394248␤»
jnthn grr
rakudo: say pi.WHAT
p6eval rakudo 9a4981: OUTPUT«Num()␤»
colomon I think TimToady has a real good case for making it a RatStr 21:40
TimToady constant pi is export = 3.14159_26535_89793_23846_26433_83279_50288; 21:40
jnthn Having an irrational number being a Rat is irrational!
TimToady I see no 'e' there...
jnthn my constant pi = 3.14159_26535_89793_238e0; 21:40
From Rakudo.
colomon TimToady: pi.perl should totally return the .Str form
jnthn pi.perl should probably do whatever $any-other-num.perl would do ;) 21:41
TimToady jnthn: well, that's not according to spec, then
jnthn TimToady: Then I think the spec is being silly. 21:42
lichtkind is pi officially part of prelude?
TimToady yes, and so are e and i 21:43
TimToady it's fine by me if a RatStr also provides a pre-converted .Num value 21:45
TimToady likes allomorphic literals 21:45
jnthn Is RatStr still multiple inheritnace?
ah, just found the bit in S02. Yes. 21:46
TimToady last I heard
jnthn remains unfond of ending up with MI being used in CORE.setting 21:48
(It's not that it's a problem in any technical sense. I just...find MI uncomfortable.)
(As does 6model, which takes "this is MI" to mean "skip these nice optimizations"...) 21:49
masak something about this irclog.perlgeek.de/perl6/2012-05-09#i_5563296
made me write this gist.github.com/2649172
I don't know what you think. sometimes I just like stories. :)
TimToady putting on my lit crit hat, the ending seems a bit abrupt... 21:53
au that reads like the first half of a story...
TimToady why do I feel like that poor guy in Star Wars saying "Almost there...Almost there..." 21:54
masak I'm sorry, I don't know the ending to this one.
TimToady we need some young, over-confident whippersnapper to nail the heat exhaust port... 21:55
au it may worth noting that both p5 and p6 now both meets and exceeds the scope of the initial apocalypse/exegesis vision, although I'm not exactly sure how to work that into the narrative. :)
diakopter Stay on target ...
TimToady well, I'm sure I can find some bits that P5 has ignored... 21:56
masak au: I think that's all part of the tuning fork narrative. Perl split into 5 and 6, providing everything from redundancy to heterogeneity.
TimToady 'course, there are some bits that P6 has ignored too... :) 21:57
au :)
TimToady had an interesting mental sideslip the other day, when he thought "tuning fork" and said "pitch fork" instead 21:59
which...almost works...
masak :D
diakopter pitch ;pipe 22:00
masak a pitch fork has more than two branches, right? we need more Perls.
MOAR
actually, I wish someone would develop more successful Perls.
diakopter peace pipe
masak but maybe there's not niches enough for more than Perl 5 and Perl 6? 22:01
TimToady well, there are other attempts to revise Perl 5 out there
hopefully they'll turn out to be better designed and less successful than PHP :D
TimToady s/and/or/ 22:02
masak there are parts about perl5i that reach halfway to Perl 6 and then stop.
like, they have a Str.reverse 22:03
that's about what you'd get if you stopped being inspired by Perl 6 about 2008, I guess :)
hm, seems .flip was born in 2009. 22:04

tadzik lichtkind: tablets.perl6.org/appendix-e-exciti...-construct shouldn't "when 'g'" be "when /g/"?
also, the top-left if seems to have some trailing }} 22:20
lichtkind tadzik: depends if eq is nuff 'g' works too
tadzik lichtkind: but the Perl 5 version uses =~ /g/
so that's more like when /g/ than when 'g'
lichtkind right 22:21
the braces are added in translation
i fix that
