tadzik hello pmichaud 09:52
masak is curious about what exactly mark_commit is... 09:53
jnthn: could you explain? I don't want to disturb pmichaud while he implements it :) 09:54
pmichaud mark_commit is the opcode that handles ratcheting
masak ok, gotcha.
pmichaud essentially, it has to throw away backtracking state but preserve captures 09:55
masak right.
and those are generally slightly coupled, so the challenge is to decouple them some.
pmichaud right. As I've been working on it and thinking on it heavily the past couple of days, I'm a little surprised it's the ratcheting that is causing issues. usually it's the non-ratcheting case that is problematic. 09:57
masak yeah. 09:58
masak remembers the headache of *finally* understanding and implementing backtracking and quantifiers for GGE... about five times :P 09:59
jnthn pmichaud: github.com/perl6/nqp/commit/87bb1c...40307849fd
pmichaud: You may want to revert that commit before solving things the "proper way" :)

pmichaud okay, in QRegex the relevant code is "regex_commit" 10:07

tadzik yeah, I'm quite sure I don't like any of the predefined topics, so I must figure out some great fun and a not bad mentor
masak .oO( ever tried to put a mentor in a bottle of Diet Coke? ) :P 10:10
pmichaud I think that causes the mentor to spew.
10:10 sergot joined
masak well, some kind of reaction is assured. 10:10
pmichaud it's much easier to get a Diet Coke into a mentor than vice-versa, though. :)

moritz jnthn: S11 says "Every C<UNIT> gets a lexically scoped C<EXPORT> package automatically. 10:44
"
jnthn: but we give it an our-scoped EXPORT package, so that it can be accessed from the outside 10:45
jnthn: should I change the spec? or is our implementation just a shortcut?
another weird thing: 10:47
Any C<proto> declaration that is not declared C<my> is exported by default. 10:48
but 'my' is usually the default
jnthn moritz: Huh?
moritz: Our UNIT::EXPORT is lexical.
I'm sure it is...
moritz so 'my proto' usually behaves just the same as 'proto', except when exporting is considered? 10:49
jnthn: oh, I might be wrong here
jnthn moritz: proto defaults to "my" too, since it's a sub
moritz yes that's the odd thing about that statement 10:50
jnthn (methods aside, which default to has)
Yeah
S11 has a few dubious parts ;)
That part feels like it was written before we changed subs to be lexically scoped by default.
I mean, we can detect explicit "my" and export it but...it feels weird. 10:51

Woodi hallo 11:33
I got that now .get on socket strips last \n but not \r 11:34
it is intentional or should I check eg. on Linux ?
11:34 benabik left
moritz it's not intentional, I think 11:35
but I don't know how it is supposed to work
ie on which level the \r\n gets transformed to \n
masak should it strip things at all?
.get sounds fairly low-level
moritz .get is what gives you a line
and autochomp is the default 11:36
Woodi it removed both in November I think
11:43 jaldhar joined 11:44 spider-mario joined
Woodi moritz: I think that it is better that send/get use \r\n form becouse in net protocols OS related fixes can not be right thing to do... 11:47

jnthn I'll probably pull this into qbootstrap later today and see how far it helps there. 12:16
pmichaud this still doesn't have transitive LTM yet
I'm not likely to get that before today's release.
jnthn Yes, that's the other thing qbootstrap needs.
pmichaud but I'm not as concerned about that from a release perspective -- it's not really a user-facing bug like #107254 is.
jnthn Right. 12:17
pmichaud gist.github.com/2718535 # also from RT #107254
(formerly RT #112148)
all spectests pass in rakudo 12:19
looks like it's time to commit and push :)
Woodi pmichaud: from where map gets $_ in last gist ? it to functional for my mind yet... 12:21
pmichaud Woodi: you mean in the 2718518 gist? 12:22
Woodi yes
and what $match realy is ? list ?
pmichaud Woodi: from ($match, $match<w1>, $match<w2>, $match<w3>)
$_ is set to each of those values one at a time 12:23
masak r: .say for map { $_ * 10 }, <1 2 3 4>
p6eval rakudo b390e8: OUTPUT«10␤20␤30␤40␤»

pmichaud $match is a Match object -- it contains the result of the match.

Woodi it looks there is no order in Perl6, things works from left to right and in other directions too :)
pmichaud there's more than one way to order it, yes. :)
masak Woodi: the idea is that it's up to you, the programmer, to tell the story in an order that makes sense.
pmichaud sometimes "subject verb" makes the most sense, sometimes "verb subject" makes more sense. Perl 6 allows both. :-) 12:26
moritz \o/ commits 12:27
masak in story-telling around the camp fire, it seems that there's some use to end-loading sentences for suspense. in programming, suspense isn't often what you want to achieve, and up-front details are preferable.
hence for example .subst(:g, q["], q[']) from yesterday.

tadzik so in about 3 hours
pmichaud tadzik: perfect, works for me. Apologies for causing the delay. 12:54

Then it's basically a way of doing futures.
tadzik pmichaud: you're not causing the delay :)
moritz pmichaud++ # mark_commit fix 12:55
masak jnthn: I thought it wasn't a question of that, but of a by-need kind of semantics.
moritz: what I like about DEFER is that it's a transitive verb and so the block that comes after naturally becomes its direct object.
12:56 derrazo joined
moritz masak: I like it too. And I wasn't quite serious with LATER 12:57

pmichaud I've just noticed that the .gist for Match objects looks.... backwards. 13:54

moritz pmichaud: but you're not the first to complain
p6eval rakudo d43876: OUTPUT«=> <xy>␤ a => <x>␤ b => <y>␤␤»
pmichaud I mean with the fact that the 'x', and 'y' are in angles 13:55
even though they aren't keys
jnthn PerlJam: As in, invoke it?
masak pmichaud: I don't understand that criticism.
pmichaud how does one get to the 'x' there? By using $<a>
masak pmichaud: <x> means "the string 'x'"
moritz a and b are the keys, that's why the appear left of =>
jnthn PerlJam: Just wrap a PAST::Op.new( :pasttype('call'), ...the thing... ) around it 13:56
pmichaud <x> means "the string 'x'" as long as there aren't any spaces in it.
jnthn PerlJam: If you mean what I think you mean :)
masak pmichaud: it's the .gist format, not .perl
pmichaud r: grammar XYZ { token TOP { [ $<a>='x y' ]? $<b>='z' } }; say XYZ.parse('x yz')

pmichaud it just seems like an odd use of angles to me, that's all.
moritz pmichaud: what would you prefer? 13:57
PerlJam jnthn: If I've got PAST::Op.new(:pasttype<call>, $code); and I want to checkthe return type of executing that code, how do I do it?
pmichaud I'd be okay if it was some other bracketing character that didn't accidentally pun with the meaning of $<...>
masak pmichaud: how about ''?
pmichaud I'm wondering if q[...] might be better. 13:58
masak that would highlight the string nature of the strings.
yeah, q[] wfm too.
jnthn PerlJam: Use the :pirop('type_check__IPP') node that I mentioned the other way around it, and then you can put that in an if node.
pmichaud anyway, the angles keep throwing me off because instinctively they look like keys or <subrule> thingies. 13:59
jnthn PerlJam: Assuming you mean "check the return type it produces at runtime when we run it"

pmichaud yes, I suppose it does make sense to depend on .gist, since it's the canonical 'say' output format.

Fix bug with subcaptures receiving empty hash entries from outer match quantified captures (RT #111286).
 15:35
pmichaud re-spectesting rakudo now. 15:36
jnthn peers curiously at the patch 15:39
masak peers curiously at the RT ticket
pmichaud captures normally keep track of $!regexsub, which is the sub that created the capture 15:40
then the CAPHASH uses information from the $!regexsub to populate empty arrays
thus: regex abc { <a>* } will end up with an entry in the 'a' hash slot 15:41
even if no <a>'s actually match
15:41 s1n joined
pmichaud but in the case of 15:41
regex abc { <a>* $<b>=b }
the $<b> match object really shouldn't be tied to the 'abc' regex
it's a "subcapture", which is only just the text of the capture 15:42
what was happening was that the match object for $<b> kept the reference to the outer $!regexsub
which meant that when someone asked for hash entries, it would construct an empty list to represent the quantified <a> captures
jnthn oh! 15:43
pmichaud somewhat telling is something like:
r: grammar XYZ { rule TOP { [ $<a>=x ]? $<b>=y [ $<c>=z ]? } }; XYZ.parse('xyz').<b>.keys.say 15:44
p6eval rakudo d43876: OUTPUT«0␤»
pmichaud ummm.
r: grammar XYZ { regex TOP { [ $<a>=x ]? $<b>=y [ $<c>=z ]? } }; XYZ.parse('xyz').<b>.keys.say
p6eval rakudo d43876: OUTPUT«a c␤»
pmichaud there.
the $<b> match object was tied to the TOP regex, and thus it thought it needed empty lists for $<a> and $<c>. 15:45
dalek ast: 343a61d | (Solomon Foster)++ | S (2 files):

Spec halfwidth corner brackets for Q[] equivalent

This is primarily to improve output of strings that mostly want to be complete quoted, to avoid cluttering such output with Q[]. But to allow it for .perl output, we have to allow it on input too.		 17:18

icwiener In the announcement, "-I and -M command-line options" stands a bit lonely there, no? I mean, another half-sentence explaining what those options do, might be nice.
masak right.
but this is the first thing in the spec that isn't latin-1, no? correct me if I'm wrong.

adu TimToady: I agree it's not ideal, but I don't live in China, so maybe it is 17:52
lucas_ I see that Perl 6 embraces operators that are not ASCII. This design decision is documented somewhere?
sisar comments welcome
TimToady lucas_: yes, S02 says: In the abstract, Perl is written in Unicode, and has consistent Unicode 17:53
semantics regardless of the underlying text representations.
ASCII is so, like, 2nd millenium :) 17:54
actually, I malign the 2nd millenim, which used a far richer character set than ASCII, at least until typewriters were invented 17:55
*nium
so chalk it up to 20th century madness 17:56
PerlJam 19th century even. We're still living with the legacy of Herman Hollerith
adu like crosses and double crosses and backwards Ps
TimToady is waiting for the whine about characters being hard to type now :)

TimToady under Gnome, there's a CTRL-SHIFT u 263a sequence to enter any char you know the code of
I generally use a Compose key in the termianl to get characters like «»
tadzik and the release's done 18:04
TimToady I use an input method like anthy to get characters like 漢字.
lucas_ Oh, I must learn all these ways of entering chars...
tadzik thanks for flying with tadzikair, I wish you an enjoyable stay in #53, "MadMongers"
TimToady sometimes I use a little program that scans the Unicode database for names, and then cut and paste
often there's already an example of a charcter you can reuse from the current window
or the current file 18:05
anyway, TMTOWTDI applies
lucas_ thanks for the tips
diakopter my cow-orker doesn't like me calling my Java program with a 500-line main() method a "script". 18:06

lichtkind this whole thing smells liek a bug
colomon moritz++'s, I should have said.

lichtkind i understand now

sorear++'s substr(-rw) is not pure Perl 6
lichtkind TimToady: thank you but wheres the difference to eager context ? 19:47
moritz eager context reifies
but reifying not only occurs in eager context
but also when accessing elements of lazy lists
or iterating them 19:48

if any.

masak put differently, 'eager' is the boring variant between 'lazy' and 'hyper' :P 19:52
TimToady well, hyper is boring compared to race
lichtkind TimToady: so its nothing more then compute or give me the next element? 19:53

i know lot of people question reality of alchemy thats ok :) 19:58
TimToady "reify" is a concept, not an officially specced API 19:59

lichtkind you clearly not evolved ebough for alchemy :)
ah enough
TimToady well, I have my chemistry textbooks, and I don't recall that they mention supernovas either...
masak lichtkind: is a skeptical mind a no-go for doing alchemy?
if so, I'm probably toast as far as my alchemical career goes... 20:06
moritz lichtkind should tell the folks on lesswrong.com :-)
masak that's a discussion I'd pay to see.
moritz not 20:07
PerlJam masak: wouldn't that be "alphysy" to parallel alchemy ?
lichtkind masak: being close minded is a no go :)
moritz eeks, it seems that deduction of string sequences relies on numeric comparisons :/

masak hoarding to me has the connotations of people buying and stocking things because everyone else is doing the same.
TimToady land grab, back in the days when no one was thought to own the land
and grabbing your own hammer is certainly not stealing 20:23

uh, I mean whatzitcalled...
isBEKaml yeah. :D
tadzik adu: did you see perl6advent.wordpress.com/2009/12/2...-actions/?
adu I think my problem is that (1) I don't understand how to get stuff from $/, and (2) I don't know what kind of return is expected 21:28
when I tried to write parrot-nqp actions, it complained greatly that I wasn't returning PAST nodes 21:29
jnthn You don't return, but rather "make". And you take $/ as a parameter.
masak adu: it's a towel. so here's the thing.
adu: I had lost that towel the previous night. literally lost it. 21:30
turned out in the pitch darkness of the sauna, someone else had accidentally nicked it.
I got it back, and I was so happy to have it back that I put it on my head.
21:30 s1n left
adu so I know $<value> is the same as $/{'value'} but whenever I try $/{'value'}{'subvalue'} I would expect it to work, but it doesn't 21:30
masak I like that picture because I'm looking suitably annoyed by having my picture taken.
adu masak: lol 21:31
masak showing a face that seems to say "you've never seen a guy with a towel on his head before?"
adu: probably $/{'value'} is a list, and you need to do [0] or something in between. 21:32
adu another thing, is when I "say $x.parse()", is it dumping the $/ corresponding to TOP? and is it a hash? or a list?
masak adu: reason for $/{'value'} being a list: you used a quantifier, like * or ?
adu: the thing that comes out of .parse is always a single Match. 21:33
adu: think of a Match as having both hash and array nature.
