TimToady re "class is Foo {...}", you can currently use class { is Foo; ... } as a workaround 00:48
also :: parses as a package name, and could be forced to mean anonymous
std: class :: is Foo {...}
p6eval std 25322: OUTPUT«ok 00:02 33m␤»
TimToady much like you can currently say "sub & is bar {...}" 00:52
or "my $ is baz = 42" 00:53
if (state $)++ is perhaps a better example 00:54

skids /me may put some work in on WITCH this weekend (www.perlfoundation.org/perl6/index.cgi?witch) 01:51
It;s been a year -- any characters change their meanings?
TimToady probably 01:53

TimToady sorry, got a phone call, looking again 02:24
skids Actually I was kinda worried I had created some sort of hour long distraction, not what I wanted to do :-) 02:25
TimToady [] is now used to disambiguate multiple metaops 02:27
basically any infix maybe have [] around it without change of meaning 02:28
$a [+] $b is same as $a + $b
but you can distinguish X[+=] from [X+]=
(description of reduce should probably mention that it only takes infix ops too) 02:29
02:29 icwiener_ joined
TimToady I think you missed use of [] to declare a shaped array 02:30
{N} and {N..M} in regex are wrong 02:31
it's just ** N and ** N..M these days, though a closure is allowed after ** 02:32
skids OK, I'll get all that sorted. Glad to see I linked to a copy of the Synopsis that got updated -- I'll just click through all the links and see if it still describes what I put. 02:34
TimToady in lparen, the (<>) entry is wrong
() is just capturing, <> is metasyntax, and they're unrelated
though <( and )> are standalone tokens indicating start and end of official match 02:35
skids Ah. That was probably my perl5 instincts getting the better of me heheh. 02:36
TimToady maybe you meant <(...)>, but that's <{...}> these days
02:36 [particle] joined
TimToady + is no longer a twigil, * now indicates contextual variables defaulting to global 02:37
skids Yeah I saw something about the + twigil holocaust the other day. 02:38
TimToady oh, we also add &[+] as a short name for &infix:<+>:(Any,Any)
(or something like that) 02:39
- may now be used (along with ') in the middle of an identifier eat-fred's-sock($x) 02:40
skids notes to update verbiage about that in underscore 02:41
02:42 [particle]1 joined
TimToady I do not see how - has wildcard uses in versions 02:43
- and ' aren't quite equiv to underscore 02:44
_ is simply considered alpha, while - and ' require a following alpha
(and may not occur at the front)
02:45 icwiener left
TimToady oh, just a nitpick, technically - isn't a dash to a typographer; dashes are longer, hyphens are short, and - is somewhere in the middle 02:46
er, minus is somewhere in the middle
SamB - is an ascii char
I don't think it means much in particular to a typographer?
02:48 shinobi-cl joined
skids Yeah I'm one of those people who still use -- myself, point taken. 02:49

SamB now, in a given context it probably means something to their typesetting software ;-P

digitalicarus I use Perl 5 a lot at work and in general. I'm curious about learning new things, but am torn... 04:46
It seems like all the interpreted languages do basically the same things. Why make a new Perl. Is it a matter of syntactic taste? 04:47
shinobi-cl look for roles
for me, is the best thing
and junctions too
simcop2387 digitalicarus: well syntactic issues, and lots of features people wanted, and things like that 04:48
digitalicarus I'm not trying to be derogatory, just curious. I'm very happy using Perl5, aside from cumbersome syntax for oop. I've been very tempted by ruby's block friendly syntax. 04:49
simcop2387 i can't say for sure but i believe a number of things like that are addressed (i haven't followed perl6 as closely as i wish i had been) 04:50
digitalicarus Does Perl6 attempt to offer any performance advantages?
diakopter no. no one tries to improve performance anymore. I think everyone just forgot about it.
simcop2387 i think performance is best answered over in Parrot currently 04:51
shinobi-cl digitalicarus... use the library called Moose for perl5
it will make oop much easier
no more 'bless' needed 04:52
TimToady digitalicarus: Perl 6 is *potentially* faster than Perl 5 because the optimizer has more information, but we're concentrating on "correct" before "fast" 04:53
fast will come later 04:54
digitalicarus I guess my questions are aimed at utility. Is there anything I can do in Perl 6, ruby, python, etc that I can't do in Perl 5?
04:54 hercynium left
diakopter digitalicarus: for interesting ideas/thoughts about optimization of dynamic languages... see tartley.com/?p=456 and steve-yegge.blogspot.com/2008/05/dy...-back.html 04:54
TimToady digitalicarus: these are all turing complete languages, so the official answer is "no" 04:55
but there are certainly differences in what is easy 04:56
04:56 alester joined, [particle]1 left
digitalicarus There is some difference in accessibility of APIs. If I want access to a new type of device in a fledgling language, I must code it in C with language X hooks or wait for someone else to. 04:57
shinobi-cl well.. good night all!
04:57 shinobi-cl left
TimToady here's fibonacci in Perl 6: 1,1...&[+] 04:57
Perl 6 will have a better native interface than Perl 5 04:58
if for no other reason than Perl 6 can actually declare APIs with C-like types 05:00
at least for primitive types and simple structs
and the OO doesn't require translation; it can just encapsulate the actual C struct 05:01
digitalicarus I really enjoy the freedom of Perl 5, and I feel like it's more creative and artistic a syntax than some other interpreted languages. I suppose it all comes down to intuitive syntax and getting work done quicker. I hope that Perl 6 carries on the legacy of syntactic freedom. More than that I hope it gets its killer app. 05:02
After all, Ruby would be a lot more obscure if it weren't for Rails.
TimToady Perl 6 is all over freedom, and the killer app will come
it's a controlled freedom, so you don't do it accidentally, but all the defaults are tweakable underneath if you want 05:03
basically, things that seem generalizable in Perl 5 but aren't really, actually are generalizable in Perl 6 05:04
digitalicarus I will start looking into Perl 6. I've looked at Ruby and Python and can't fabricate a reason to learn another language that can't really do anything I can't with my meager Perl 5 chops. 05:05
Perhaps I'm not writing advanced enough code to need cutting edge language constructs :) 05:06
TimToady that's okay, we've tried hard to keep Perl 6 a language you can learn small-end first
but they'll be there when you need 'em 05:07
assuming we finish implementing it, of course...
digitalicarus Is my Perl 5 knowledge extensible to Perl 6? I mean, will I have a leg up on Perl 6 if I'm okay at 5?
TimToady certainly, there aren't many things you have to unlearn
$foo[$ix] becomes @foo[$ix], for instance 05:08
but that's more regular
and we use .foo instead of ->foo for method calls, for various reason
reasons
and foreach loops are now written for @list -> $elem {...} 05:09
05:09 eternaleye left
TimToady because $elem is actually a formal parameter to the block 05:09
digitalicarus Seems to be influenced by the terseness of Ruby 05:10
TimToady in some ways, but hopefully better designed
certainly -> $x {...} is like ruby's {|x| ...}
interestingly, ruby is borrowing the -> form, last I heard 05:11
digitalicarus I thought I read somewhere that Matz was inspired in part by perl 05:12
simcop2387 the main thing i'm waiting for out of perl6 is parrot, its a very nifty idea
TimToady 60-70% of ruby syntax is straight out of perl
digitalicarus gtg. I will try to come back with more stimulating conversation after more research on the Perl 6 and parrot projects.
TimToady I'm waiting for Perl 6 to run on any platform
digitalicarus see you
TimToady have fun

it can only be known at run time
pugs_svn r25325 | lwall++ | [S19] $?PROGRAM makes no sense 05:21
05:21 bigal joined
shinobi-cl i used to work on delphi many years 05:22
one of the things i liked about it was the "with" keyword... which works just like "given"
TimToady it's another topicalizer, but I think "given" is more natural; "with" is too non-specific 05:24
shinobi-cl bue being that given is used as the switch-case, is not really an equivalent to with, since it limits you sometimes.. for example, using a case inside a "with"
yes, i agree, with is too general 05:25
pugs_svn r25326 | lwall++ | [progname] program name needs to come from PROCESS namespace
shinobi-cl the idea of the "with" in delphi was mainly to type less code 05:26
with qryRead do begin Writeln(Fields[0].AsString); Next end.... without with, you had to write qryRead in front of Fields[0] and Next 05:27
pugs_svn r25327 | lwall++ | [progname] botched previous patch 05:28
shinobi-cl it helped a LOT in code readability
TimToady that's basically from Pascal
shinobi-cl yes, pascal 05:29
TimToady we almost have the same, as long as you put an extra . on the front
given %foo { .<foo> = .<bar> }
shinobi-cl but if you use a given inside that given, you loose the default variable 05:30
or is "lose"?
TimToady lose
but then it would be potentially ambiguous anyway 05:31
and you can say given %foo -> $f { $f.<foo> = $f.<bar> }
even if %foo is very long
bigal would like to help with P6, but not a great C programmer... anyone need help not C oriented?
TimToady well, in that case, $f<foo> = $f<bar> is fine
most of the folks around here aren't doing C 05:32
lotta people writing tests
bigal k, thought p6 written in c
shinobi-cl oh i see... its ok then.... even better that "with"
TimToady pugs is written in Haskell
the STD parser is written in Perl 6 :)
elf is at least partly in ruby 05:33
bigal rgr... not a Haskell xpert either (unfrtnly)
TimToady but you can program in Perl 6 if you write tests :)
bigal I'll back off then... was hoping to contribute. not sure how to help though with my skill set.
TimToady or there are docs, wikis, etc
even just blogging your learning curve can be useful 05:34
bigal rgr that, can do docs, wikis, etc. Just point me to the POC. I'll do 6hrs weekly
05:34 icwiener_ left
TimToady well, most of the Perl 6 folks hang out here, and most of the Parrot folks on #parrot on irc.perl.org 05:35
shinobi-cl i have a not official wiki... you can help there if you have some time :) and you can learn some perl6 from there... nothing like this channel, but enough for starting i think
TimToady various people do various bits of it
bigal rgr... [email@hidden.address] shoot me some work, I'll do my best 05:36
TimToady and nobody will be offended if you ask around
would you like a commit bit to the pugs repo to start with?
bigal perhaps, Im win32/Suse10.1/opensolaris os kind of person... anything for the team. Lord know's Ive benefitted from perl enough to pay back. 05:37
TimToady could always use help in portability 05:38
pugs_svn r25328 | wayland++ | S16-io: Reorganised everything, grouping things together a bit better. This is only a

bigal ok, I can offer 6 hrs weekly min, plus anything I can provide from my servers... owe alot to perl. 05:40
mikehh bigal: have you looked at www.perlfoundation.org/perl6/index.cgi
TimToady I've sent you a commitbit to the pugs repo; which contains the specs and test suite 05:42
it's customary to add yourself to AUTHORS as a test checkin
for pugs repo stuff the principle is forgiveness rather than permissions, so hack away 05:43
bigal checking www.perlfoundation.org/perl6/index.cgi now... I've donated 'lots' for me in $$ ($500) but worth it for me 05:44
afraid of pugs as I am not a pugs guy. Self taught perl/C/Java guy... hate java, never touching C again without an order :>) 05:45
Can learn pugs though if docs...

just go ahead and patch the Rakudo Test.pm? (making sure to run the spectests before and after) 11:41

masak also on the agenda for the weekend: a review of mberends' Pod suite, maybe some proto hacking, maybe maybe implementing unpack in moritz_ unofficial prelude. 14:42
wolverian: any impressions so far that you'd like to share? I'm interested.
jnthn proto hacking? 14:43
wolverian masak: it's incredibly easy to get on a level where you can actually form sentences easily and have conversations (albeit not very fluidly).
masak: I'm not familiar with esperanto or other constructed languages, so I can't really compare.
masak ok. 14:44
14:44 shinobi-cl left, shinobi-cl joined
masak so far I've been a bit put of by the grammatical vocab of Lojban. 14:44
wolverian all I've learned so far has made perfect sense in the minimalist logical context the language is based on, so I'm happy.
masak but maybe that'll eventually lure me in as well. :)
jnthn is too tied up with Slovak and Russian to have time for much other languages ATM. :-| 14:45
masak wolverian: do you have any sense of the size of the international Lojban community?
jnthn: Slovak and Russian sounds plenty.
wolverian masak: lojban.org is somewhat active, as is #lojban; some hundreds.
masak: not a large community.
masak was at a lecture by Douglas Hofstadter yesterday
heard him speak about his translation of Eugene Onegin. 14:46
wolverian: still, larger than many other conlangs.
certainly among the 10 largest.
14:46 maerzhase left
wolverian oh, certainly. 14:46
I'm thinking of making an attempt at porting the grammar to parsec over the summer 14:47

masak :) 14:47
wolverian or perhaps perl 6 rules...
(thing is, if I do it in haskell, I'll probably get credits for it from the CS dept) 14:48
("haskell workshop")
masak anke konsideras lernor Ido 14:49
jnthn "masak is considering lerning Ido"?
masak jnthn: 'also', yes
with the extra twist that 'learning' is a future infinitive. 14:50
wolverian pfft, Ido has verbs, and nouns, and all that.
much too complex. :)
masak wolverian: :P
wolverian: have you looked at Toki Pona?
14:50 cognominal left
masak it's the latest minilang craze among the young Esperantists. 14:50
wolverian masak: yes, it's cute. 14:51
masak I don't much care for it. no language which calls pee 'yellow water' deserves my respect.
wolverian heh.
14:52 cognominal joined
wolverian pinca in lojban. 14:52
gotta run, cheers. 14:53

And type inference, and lambdas (in C#...) and other goodies. 17:43
masak Nom-: if you ask me, there's less and less reason to, as well. there are fewer urgent things nowadays.
the Novmeber project will start targeting Rakudo releases by the next Rakudo release.
jnthn wonders what that will do for bug discovery 17:44
I guess we get a new batch a month. ;-)
masak jnthn: either that, or continuously from the work we might do in branches.
it's only the master branch that has to target the latest release, I should add. 17:45
jnthn Aha, OK.
Sounds good - more sanity for November development, so time can be spent more on features than chasing Rakudo.
masak exactly. 17:46
perhaps not surprisingly, this decision was reached after the adventorous time in January. :)

shinobi-cl you declared a, so is one element with undefined content. In the previuos try you specified that a is empty

shinobi-cl mmm well.. 0 makes sense to me, instead of undef. 18:44
frew I would have figured it would say that Scalar has not end method
shinobi-cl the other thing is to remove .end from the scalar protoclass

TimToady frew: um, it was the other way in Perl 5. why do you think I changed it? 19:15
frew I dunno, I just thought that this was surprising when I first saw it 19:16
but I have designed or implemented exactly 0 languages
TimToady it's also surprising when someone writes print ($x + 1) * 2 in Perl 5 19:17
frew that's a good point, I hadn't thought of that
TimToady if you really want a little visual separation you can always say foo.(1,2,3) 19:18
frew of course
or just not use an anonymous array
TimToady but p6 get a lot of its power and extensibility from being consistent about postfixes
frew well, I would much rather consistency, I was just curious of the motivation 19:19
TimToady the consistency runs the other way too: you can be guaranteed that foo() will always call a function
even if foo is otherwise a keyword 19:20

what about with named args?
elems(:array(1,2,3,4))?
or do I need more parens?
TimToady the parens on an adverb are not arguments to anything, they're just a list
so you don't need extra parens unless something binds that list to a scalar later 19:30
in list context, parens are a no-op
frew ok
TimToady (same as in p5, btw)
frew so they aren't necesary unless they have to clarify for parsing
TimToady yes, that's what parens are for :) 19:31

frew yessir
Matt-W Just leave off the type annotation, I think 21:38
frew but I have to put a sigil right?
Matt-W you do, but if I remember my Perl 6 correctly (and I might not), if you put a single scalar and give it a single array with an @, it should come out in the scalar as an array reference
I may, however, be wrong about that 21:39

it's not a big deal at this point
it could def be done with a Multi sub

Matt-W it's not really particularly relevant in terms of what .perl does
frew yeah
Matt-W because you can take its output, feed it back into an array or arrayref and it'll work
frew but I am just thinking that it would be nice for REPL to call .perl on everything
oh I see what you mean
I am just thinking basically for a users POV 21:46

frew maybe there isn't a distinction
Matt-W Well I think generally, everything that's not a value type is a reference
just poking through S02
frew interesting 21:59
Matt-W all @ means is that the object at the other end does Positional
and % requires that the object at the other end does Associative
it's syntactic sugar
frew but if I do foo(@huge_array) it's not a huge deal
Matt-W from a certain point of view
no I think that's passed by reference
frew that's excellent
Matt-W S02 talks about how value types are distinct from other types
21:59 japhb joined
Matt-W and Array is specifically mentioned as not being a value type 22:00
frew I need to read more than just S29...
Matt-W it is worth it
although there's a lot to digest
I need to re-read the whole lot again at some point
frew well, I've had my nose in testing functions, because that's pretty easy
at some point I'll learn the deeper stuff
I'm not in a huge rush at this point
Matt-W also, on the question of .perl 22:01
S02 states that .perl assumes that the output will be used to regenerate the original object in item context
so it always doing [] around lists is most definitely correct
frew that's fine
especially with my new knowledge of references in perl6
Matt-W just... don't kill me if I turn out to be slightly wrong :) 22:02
frew I wouldn't
like I said, it's not a huge deal at this point
I am just trying to make my local perl6 be nicer to me
Matt-W but the wohle references thing is definitely different in perl 6
I have to go now
frew alright, station 22:03

s1n oh, yeah, for now just submit that to the pugs repo

s1n no
rakudo uses a file called t/spectest.dat, that's in rakudo's git repo 22:21

jnthn Ah, then the Whatever is probably a special case...but I think you're right...too tired to really think about much ATM. :-) 23:31
I didn't think of a good way to implement ff yet...
frew pugs: 1 ff 2
p6eval pugs: OUTPUT«*** No such subroutine: "&infix:ff"␤ at /tmp/ub4wzzmzFB line 1, column 1 - line 2, column 1␤»
jnthn I'm not sure I thought of a bad way yet either... ;-) 23:32
bacek jnthn: I'm implementing ff ATM :)
jnthn bacek: Nice! 23:34
Will be interested to see what you come up with.
Esepecially, how you plan on storing the flip-flop state. 23:35
bacek src/classes/Flipflop.pir 23:36
Same way as Range
Or it is bad idea?
23:37 kane__ left
bacek It is... 23:38
What expected result for "for (1..5) -> { $_ if 1 ^ff 0 }" ? 23:46
2..5? 23:47
