17:21 Jedai joined
fglock TimToady: ah, much easier than what I was doing - thanks! 17:22
does $pos++ increments .graphs?
TimToady it increments whatever "char" means in this unicode mode. 17:24
which is default graphs
but under "use codes" or "use bytes" it would be a smaller bite 17:25
all subject to the maximum and minimum abstraction levels allowed by the stirng
fglock k 17:26
TimToady a string marked as "max bytes" will always increment by bytes even under a higher level
and it is likely an error to increment a "min codes" string under use bytes 17:27
in other words, it's okay for narrow characters to pretend to be wider, but not the other way around. 17:28
(as long as Unicode semantics are preserved) 17:29
(which means it is probably required to know the encoding of the bytes to know how they would have been treated if they'd been codepoints) 17:30

ruoso I was thinking this days... One interesting feature would be to create a regex modifier to allow matching of unaccented characters, like /a/ with the modifier would match both 'ã' and 'a'
offby1 I bet you'd find characters where it's not clear if it's accented or not 18:19
just my general pessimism 18:20
ruoso offby1, that would depend on the locale
as \w already does
fglock ruoso: I think you can - maybe take a look at unicode properties
ruoso there's Text::Unaccent that does that by mapping
but having that as a regex modifier would be really interesting... 18:21
consider you have a html that you want to make some words bold, but one of these words have an accent, but you still want to make bold the word without the accent... 18:22
PerlJam ruoso: I'm pretty sure that is already specced and is not a regex modifier 18:23
ruoso PerlJam, any clue of what I should look for in the spec? 18:24
PerlJam not really. 18:26
But taking your example, you would do something like s/(word&mumble)/<b>$1</b>/g; where mumble is the thing that would include matching the appropriate unicode properties. 18:29
Jedai But is there really a case where you would like to match ANY accentuation of the same letter ? 18:30
ruoso yes...
Jedai, accepting mistyped names
Jedai Ok... 18:31
ruoso that's quite common in places where you accented letters in people's name
s/you /you have /
Jedai well, not as a regex modifier then ? Rather a letter by letter thing ? 18:32
ruoso letter by letter? hmm
doesn't seems like a good idea 18:33
this is what I do today... so no gain...
Jedai I mean something like a modifier who take letters as arguments
ruoso but... why would I need to pass the letters as arguments? 18:34
Jedai If you accept any accent, you accept things really different from what you want 18:35
It's really the same as Text::Unaccent
ruoso yeah... except that I can make a s/this/that/ and substitute both 'thís' as 'this' as 'thîs' 18:36
which is not that simple with p5 regexes 18:37
Jedai Yeah, I see your point :)
And it's pretty screwy to do with Text::Unaccent too 18:38
TimToady with Perl 6 you could presumably transform the string to NFD and then under "use codes" match the base character separately from the accents. 18:40
ruoso TimToady, hmm... how the code for that would look like? 18:41
Jedai The joys of unicode... 18:42
TimToady well, depending on how we represent Unicode properties, something like (<-M>)(<M>*) matches any grapheme and splits it into base and accents, assuming NFD 18:44
ruoso hmmm... I see... 18:45
ayrnieu (I lament the loss of the yen operator -- because I have it on my keyboard. Well, I can still use it for screen's cmd_char.)
TimToady just use it for backslash. :¥ 18:46
er, :\
ruoso but still... what if I want to match, but I simply don't want to care about it, as it is for case-sensitiveness.... 18:49
TimToady don't want to care about what? the accents? a<M>* 18:50
or do you want sugar for lexically scoped not-caring? 18:51
ruoso yeah... but this way I still have to go through all the chars that may be accented and add the <M>* after it
18:51 Lorn joined
TimToady so you want sugar for lexically scoped not-caring 18:51
ruoso I mean $str = 'João'; $str =~ s/(Joao)/<B>$1</B>/ 18:52
TimToady that could likely be arranged.
could even temporary match a chunk of string with NFD even if you never explicitly convert
fglock define your own 'regex_mod_external:<noaccent>' ?
TimToady maybe able to list the accents you want to ignore 18:53
ruoso optionally, yes... that could be usefull... 18:54
But I'm more in the sense of just ignoring it, as in ignore-case...
TimToady maybe just :insert which defaults to :insert(/<M>*/) or some such
hmm, insert too generic, but noaccent is kinda long 18:55
maybe overload :ignore
fglock :base 18:56
ruoso base seems fine
TimToady that probably works
presumably, like :i, it doesn't care whether you write the pattern with accents either, just normalizes both sides 18:58
ruoso sure...
[particle] isn't there already :base(n) for math-related stuff? 19:00
TimToady not in regex
also, like :i, only applies lexically in this rule, not dynamically in subrules
ruoso thinks this solves completely the problem 19:02

Juerd So that ń < ö < p 19:32
fglock mm - I wonder if PCR needs a Str class 19:34
TimToady there's a unicode report about sorting that goes into excruciating detail about all that. 19:38
and we already installed hooks into sort and cmp for alternate collation orders 19:43
(for some definition of installed that may not include implementation)
[particle] maybe it's for some definition of already 19:44
Juerd Neat, because Dutch has three different ways of sorting the ij. 19:46
TimToady well, who can explain the Dutch? Not even the Dutch... 19:47
Juerd Not at all.
But ij can be explained :)
It started as ii, which was like any double vowel.
And started a life of its own.
TimToady I can, of course, slang the Dutch because my ancestors were Flemish. :) 19:48
Juerd 14.oO( that explains a lot )
moritz did the Flemish invent the Flame war? 19:49
Juerd No, they have yet to invade .nl with caravans. 19:50
TimToady well, there were reasons my ancestors moved away, possibly involving flames
Juerd Trojan caravans.

svnbot6 r15545 | fglock++ | PCR - Grammar::Rule - fixed precedence of conjunctive/disjunctive ops

TimToady why not?
ruoso am I the only one who can't resolve pugscode.org? 19:53
moritz ruoso: this afternoon I had problems as well
TimToady: is that a "yes"?
TimToady dunno, but I can ping it
19:53 jesse__ joined
TimToady we don't usually forbid something unless there's a reason 19:53
so I really am asking "why not?" 19:54
moritz ok
TimToady that turns into "yes" only if nobody pipes up with a good reason
contrary to popular opinion, I don't actually know the answer to every question just yet. :) 19:55
moritz my thought was the following: if you have multiple conditions in a PRE-block and you connect them with "and", and one of them fails, you don't know which one failed...
ruoso whois pugscode.org gives a strange result...
moritz so a good workaround would be to use multiple PRE blocks 19:56
so that pugs/perl6 tells me which one failed
TimToady assuming some kind of assert-like mention of the code involved
moritz ?eval sub f($a is Num) {PRE {$a > 0} PRE {$a < 5} say $a} $f(2); f(50) 19:57
evalbot_r15539 Error: No compatible subroutine found: "$f"
moritz ?eval sub f($a is Num) {PRE {$a > 0} PRE {$a < 5} say $a} f(2); f(50)
evalbot_r15539 Error: PRE assertion failed: "&Main::f"
19:57 lampus_ is now known as lampus
TimToady just Num $a, not $a is Num 19:57
moritz ok
20:00 jesse__ is now known as obra
moritz so why does the first test in t/closure_traits/pre_post.t fails? 20:00
20:01 ozo_ joined
moritz ?eval sub foo(int $i) { PRE { $i < 5 } return 1; } foo(2); 20:01
evalbot_r15539 1
moritz at least it fails with r15530 20:02
TimToady Undeclared variable: "$i" 20:04
perhaps the closure isn't closing 20:05
it's not an int vs Int distinction 20:06
moritz well, it doesn't work if you substitute int by Num 20:07
TimToady or perhaps it's simply running the PRE before binding anything to $i, given pugs's penchant for belated reporting of undefineds. 20:08
20:08 Psyche^ joined
TimToady anyway, almost certainly a bug 20:08
svnbot6 r15546 | fglock++ | PCR - updated docs, TODO, ChangeLog 20:09

Juerd Perl Reality Enigma. 20:12
TimToady Potentially wRong Expression
Juerd Hehe
PWE { ... }
moritz Potentially wRong = Partially Right ;) 20:13
TimToady Potentially Other Stupid Thing
moritz is there something in p6 equivalent to Eiffel's class invariants? 20:14
TimToady Pink Remembering Elephants
potentially, though unspecced. I assume they're equivalent to identical PREs factored out from all the methods 20:15
so you could implement such a thing by distributing extre PREs to each method 20:16
moritz they are evaluated before and after any method call (except before the initialiser)
TimToady seems like it would be fairly easy to do even if we don't spec it officially 20:17
moritz so how would I do something like that?
fglock create a Role that adds PRE to methods... 20:18
TimToady depends on what kind of apparatus the MO folks hand us.
fglock Class->add_method( 'name', $closure does MyPre )
does this seem right? VAR(&meth).PRE.push( {...} ) 20:20
TimToady something like that, but you shouldn't need VAR 20:21
&foo.meth already calls a method on the &foo object. 20:22
only .() would be a problem.
fglock k
moritz funny... I've just written a test case that works fine inside eval(), and fails to compile outside of eval() ;) 20:30
TimToady In fact, I don't see any good reason offhand why a method declared inside a sub shouldn't just be considered a method on that &
fglock mm - anon prototype? $x = { method {...} } 20:31
with named methods, actually - $x = { method meth {...} } 20:33
moritz should POST have access to internal variables of a sub?
PerlJam doesn't quite see the unification of classes and subroutines as a good thing. 20:34
TimToady if they're in lexical scope, but it might not be best practice
PerlJam perhaps I'm just pessimistic today
moritz ?eval sub f(Num $i){my $x=$i; return 1; POST {$x > 0}} f(42)

TimToady I mostly just worry about the people who think -Opessimism is -Ofun 20:36
that set of people contains a lot of illigitimi that I have to non-carborundum 20:37
PerlJam btw, I had another idea for an article on Perl 6. "Perl 6: Where the heck is it?" I thought about trying to answer that question myself, but then decided that it would be better if I came up with some of the naysayer's arguments and such and then asked the set of questions to many of the principle players in Perl 6. 20:39

Juerd PerlJam: See also the fears document, for inspiration
PerlJam People like larry, damian,chromatic,pmichaud,allison, etc.
Juerd: thanks.
Juerd I got caught up in other work, while writing that.
Yet another subproject died :(
sili slacker 20:40
:p
PerlJam Juerd: leonardo da vinci started bunches of projects that he never finished. But you have to start them before you can finish them anyway. :-)
moritz PerlJam: well, he died. so he wasn't successfull after all ;) 20:41

sili dying makes people famous 20:42
PerlJam moritz: I don't know ... some people measure success by how many dreams you can dream.
Juerd PerlJam: Anyway, it's in quickref 20:43
moritz PerlJam: that's too philosophical for me ;)
Juerd quickref itself died too. Some of it is in Spec, but AFAIK, that's not maintained anymore either. 20:44
PerlJam I'm going to try to find time to write more about perl 6 this weekend (it might be hard since I'm going to SXSW) 20:46
Anything in particular that you guys think is lacking in terms of bring perl6 to the people?
sili PerlJam: working code 20:47
(pugs excluded)
moritz something cool about rules
PerlJam sili: pugs is our anchor until perl6-parrot comes alive.
moritz: like what? Rules aren't cool all by themselves? 20:48
moritz PerlJam: no, but what you can do with them is cool IMHO - so an example would be nice.. 20:50
specbot6 r14324 | larry++ | typo from perl++

moritz PerlJam: but then you'd have to explane a lot I guess
PerlJam moritz: explaining alot is almost the point :-) I want people to be comfortable with perl 6.
I guess I could start a tutorial or two. Or take up Juerd's flag and start fleshing out quickref 20:51
[particle] pj: keep your eye on parrot's object model, which is being implemented *now*. expect perl 6 with object support shortly after 20:52
PerlJam [particle]: is it documented in the pdd?
[particle] allison, jonathan, and mugwump have been working on the draft pdd 20:53
it's updated in the repo. i'm writing tests, and jonathan's coding pmcs
PerlJam I'm guessing parrot's object model closely mimics perl 6's now?
[particle] there's a pir-based prototype impl in compilers/smop/
of course 20:54
once we have objects and i/o, we'll release 0.5.0
PerlJam who's RM for that one?
Coke?
[particle] which one? 20:55
PerlJam 0.5.0
[particle] dunno, wheever's lucky enough to be the rm when we decide the next release will be 0.5.0
PerlJam Didn't they go to a rotating RM schedule?
[particle] yes, but we haven't chosen the release numbers yet
PerlJam oh, I see.
[particle] coke's releaseing 0.4.10 this month
PerlJam Coke++ (like he has a choice ;-) 20:56

sili PerlJam: I think a "Learning Perl 6" type wiki would be helpful. there's a lot of documentation out there, but it's not very organized and is dating quickly 21:08
it needs to be maintained, most importantly
21:14 Lorn joined 21:20 drupek12 joined
tene sili: the stuff in svn isn't dating so quickly. 21:21
sili tene: perhaps, but i think if the goal is to start putting perl6 in the hands of users, it needs to be accessible. in other words, a pretty web site 21:22
tene sili: the reason things are dating is because Perl 6 is still in heavy development.
sili tene: i understand that 21:23
tene However, if you want to volunteer to put together such a website, I'm sure it will be quite appreciated. :)
sili $newcomer doesn't, and doesn't want to bother with such things
there's a wiki up there somewhere, it just needs to be maintained 21:24
moritz sili: $noewcomer who doesn't want to be bothered with language changes shouldn't use p6 yet ;)

tene sili: I think moritz is probably right. The type of user you're trying to appeal to doesn't want to use Perl 6 until it's released.
evalbot_r15539 536870912
sili maybe
moritz tene: on the other hand once it's out we _have_ to have tutorials etc., and then it's too late to write them 21:26
tene how is it too late?
moritz well, when p6 is released, it will be in all the (tech) news and will get lots of attention... 21:27
and many people will try it...
and if they can't find suitable documentation they'll just abandon it 21:28
which is not what we want
21:29 beppu joined
tene That's probably true. 21:30

pasteling "ajs" at 63.107.91.99 pasted "example of v6 regex parsing failure" (13 lines, 609B) at sial.org/pbot/23398 22:04
ajs Am I doing something odd there, or is v6?
Or does backwhacking in rules just not work very well right now
?
ayrnieu PerlJam - I'd like simple comparisons: 'here is idiomatic $lang code', 'here is functionally similar but idiomatic perl6 code', with comments on anything interesting about the perl6, but otherwise not emphasising the comparison.
ajs v6 says: "Error in perl 6 parser: parsing error in Expression: ..." ~ $/[0]" 22:05
[particle] sure 22:07
{ return " " ~ $/[0] }
probably doesn't like that for some reason
ajs So it would seem...
[particle] although i don't see why it wouldn't work 22:08
ajs It almost smells like it's reading the previous "\\" as "\" ... I'll try dumping the P5

ajs Yeah, I just changed that { ... "\\" ... } to { ... $bs ... } where I'd set $bs to a backslash, and it worked. 22:16
seems v6 may have problems with escapes in rule-embedded code 22:17

allbery_b so, about versioning: a non-perler on #lopsa has raised a couple issues 23:09
(1) explosive complexity when a program ends up requiring 5 different versions of a perl module
(2) what happens when you end up mixing multiple versions of something like DBI?
[particle] you get what you deserve? 23:10
;)
allbery_b well, he's worrieid that it might end up becoming common practice. my take is that it's sufficiently complex and de-huffmanized to suggest "don't do that" but he still worries 23:11
personally I'd like to see a system where modules declare (a) version (b) compatibility; consumers declare compatible module versions (or don't, and risk faiure at runtime); (c) p6 finds the "best" single module that conforms or throws a compile time error saying what constraints need to be satisfied 23:14
[particle] if you're using different module versions with different apis in the same scope, that's a problem
(if it's even allowed--i imagine it isn't) 23:15
allbery_b the problem is,, wha constitutes scope?
[particle] a class or module?
allbery_b in the case of something like DBI, the underlying database foo essentally makes the scope the entire program. likewise when any module has internal state that isn't instance state 23:16
the proposed p6 behavior is IMO only safe for stateless modules
TimToady not without aliasing 23:17
it's not like we haven't talked about those issues over and over already...
[particle] again! again! 23:18
TimToady I think you're ignoring wha'ts already specced on modules that manage exclusive resources
allbery_b I may have missed them
TimToady it's also possible that it never made it from apocalypse to spec. :) 23:21
allbery_b where do I find the spec on exclusive resources? it's not in S11 wehere I would expect it
TimToady but we've certainly been discussing it recently
allbery_b huh
TimToady in p6l, for instance. 23:22
allbery_b hm, thought I was on p6l 23:23
seen lots f discussion about shaped arrays recently, but the only version stuff I've seen is snippets here 23:24
TreyHarris TimToady: yeah, i was just looking, i don't think it made the A->S transition
allbery_b: do you filter out the svn commit emails? it's been in a thread whose subject line is one of the commit logs
TimToady I guess I'll have to fix that then..
allbery_b nope, I get those 23:25
and I check my flters regularly so would notice if somehow they were getting spamfiltered
TreyHarris allbery_b: check your subject lines for /r14317/ 23:26
allbery_b hm, I've been getting those. 23:27
okay, so maybe it's the damn drugs doing the filtering :/
allbery_b needs to call $doctor and find out if there's some other alternative, this seems to only have downsides currently 23:28
TimToady it's certainly not adequately specced, regardless of how much we've discussed it.
