FROGGS hi pmichaud
BenGoldberg Should division by zero throw an exception, or return infinity? 00:18
pmichaud it actually returns Failure in Rakudo. 00:23
I think TimToady++ would ask what do you want to happen if the division by zero occurs in the guided missile controller :) 00:24

lizmat good * #perl6! 09:37
reading through S02, I was wondering whether "parens" is a good replacement for "parentheses" 09:38
yes, it is shorter, but "parens" does not occur in my Webster's dictionary
lizmat wonders whether she should s/parens/parentheses/ in the synopses 09:39
masak lizmat: might be a good idea, yes. perldoc seems to use 'parenthesis'/'parentheses' consistently. 09:40
(good * to you too!) :) 09:41

added tests for our-scoped variables
 09:57
FROGGS can somebody please review this new test file?
if the test is okay I want to push my rakudopatch 09:58
masak FROGGS: re question on L18: yes. that's one of the main points of 'our' vars, IIUC. 10:05
FROGGS: re question on L23: yes, that is right.
FROGGS masak: thanks!
masak FROGGS: why are you using classes and then calling them 'packages'? :) 10:07
I mean, they are. I was just wondering why you weren't using modules and calling them modules. 10:08
FROGGS hmmm, true 10:09
will change
10:14 anuby left
FROGGS masak: I guess I call them package and will actually use packages :o) 10:15
dalek kudo/nom: ffe441f | (Tobias Leich)++ | / (2 files):

 10:18
Heuristic branch merge: pushed 40 commits to rakudo/froggs_multibyte by FROGGS 10:19
masak um, was that branch merge intentional?
diakopter 65 yapc::na talk slots (24 20-min and the rest 50-min), and 97 non-lightning talks submitted so far
masak: I'm guessing cross-branch
FROGGS masak: no, but it doesn't hurt 10:20
masak ok.
just checking.
FROGGS masak: I could delete that branch anyway
dalek ast: 75c8a16 | (Tobias Leich)++ | S04-declarations/our.t:
use packages when we talk about packages
 10:21
masak FROGGS: test file looks good. 10:22
FROGGS thanks for checking 10:23
masak FROGGS: I didn't really understand what you were testing with the 'eval' one, and what that had to do with 'our' variables.
FROGGS masak: hmmm, I copied that from my.t, the first $e declaration could be 'our' though 10:24
but it is basically the same test as on line 12
10:26 FROGGS_ joined, FROGGS_ left
dalek ast: b0e6796 | (Tobias Leich)++ | S04-declarations/our.t:
remove redundant (and probably misplaced) test
 10:29
masak FROGGS: yeah, but it doesn't have anything to do with 'our' because there's no 'our' declaration inside. 10:34
only two 'my' declarations.
FROGGS masak: right 10:35
and if it would be 'our' it would be the same test as above
lizmat masak: so it's ok if I go ahead with s/parens/parentheses/ in S0[34568] and S11 10:45
and S12 10:46
?
diakopter TimToady likes parens 10:49
dunno if enough to want to keep them
dalek ast: cf7ea4f | (Tobias Leich)++ | S04-declarations/our.t:
fudged for niecza
 10:50
FROGGS lizmat: maybe it is enough if you do "parens (parentheses)" on the first occourance? 10:51
lizmat maybe then better to start a glossary, with terms such as "parens", "numa", "gcd" in them 10:52
numa and gcd I had to look up to make sure what they meant
tadzik numa? 10:53
lizmat see?
tadzik I see that I haven't really read the specs :P
lizmat en.wikipedia.org/wiki/Non-Uniform_Memory_Access
S02, about object identity
tadzik duckduckgo suggested: "Numa Numa (Internet Meme)"

FROGGS masak / jnthn / moritz (when awake): do you mind if I change rakudo that it will look up 'use v5' as a module too? 11:24
masak I'm not present enough to be able to answer that. 11:26
nwc10 good pm jnthn
jnthn o/ lizmat, FROGG, masak, nwc10 :) 11:27
FROGGS: How exactly are you pondering changing it?
FROGGS: In the actions?
tadzik hooray, jnthn!
lizmat I also wonder: use 5.10 should do the same thing, no? 11:28
jnthn lizmat: I hesitate on that one a bit. 11:29
11:29 pmurias joined
jnthn lizmat: It'd imply a very particular emulation, I guess. 11:29
11:29 pmurias_ joined
arnsholt investigates a NativeCall segfault 11:30
FROGGS jnthn: in the grammar... so that 5.-versions are treated as module usage
11:30 pmurias_ left
pmurias one thing we need to consider is that the spec seems to imply use v5 import the Perl module 11:31
lizmat if the goal is to allow darkpan modules that have "use 5.10" in their code to run transparently on Rakudo, some sort of support for that syntax would be needed, I suppose
FROGGS only in the token statement_control:sym<use>
pmurias re supporting use v5.10,v5.12... we definitly want to support that too, as it's also used to request extra perl features (like 'say') 11:34
FROGGS jnthn: I'll gist the patch later 11:36
jnthn FROGGS: ok :) 11:37
pmurias re 'use v5' being treated like 'use Perl:ver<5.*>' S11:497
FROGGS pmurias: right, all features turned on
jnthn just did a 5 hour timezone shift on top of only 3 hours sleep, and should not be relied on too heavily for sanity today ;)
FROGGS hehe
jnthn: I slept about 1.5 hours... because hacking till 4 a.m. and can't get to sleep because of thinking about how to implement these and that :P 11:38
lizmat remembers being in the flow and is looking forward to being it again soon 11:39
*in it
pmurias FROGGS: a basic 'use v5' as module support can be implemented with a one line change
pastie.org/7267265 11:40
jnthn FROGGS: Yes, I've taken to crashing on the sofa for an hour between leaving the keyboard and trying to sleep, doing something non-programming. Otherwise I would have that kind of problem very regularly.
FROGGS pmurias: true, even a 'v'? '5' '.'? could (something like that)
pmurias: ohh, that looks nice 11:41

11:57 asogani_ joined 11:58 asogani_ is now known as anant
jnthn anant: (answering earlier question) needs an argument so as to support prototype OO systems, where the meta-data is tied up with the object and the HOW is actually just some singleton thingy 12:00
anant jnthn: So this singleton HOW object (seems to be Perl6::Metamodel::ClassHOW.new()) actually inquires the object passed as an argument for meta-data? 12:05
jnthn anant: No, because ClassHOW implements class-based OO. 12:06
anant: It's more if you're implementing an object system along the lines of what JavaScript has, for example.
nwc10 jnthn: nqp-jvm prep still "works" on my machine apart from the 2 usual failures on nqptest 12:10

[Coke] looks like new tests caused a niecza hang when running the suite yesterday. 13:02
I just killed the offending test file.
arnsholt anant: AFAIK no-one's implemented prototype OO yet, but it can be done 13:15
13:15 PacoAir joined
anant arnsholt: so the .HOW.methods() taking in an argument is more of a future-proofing thing? 13:17
colomon [Coke]: WHAT WAS IT? 13:18
errr, sorry about the caps lock
moritz anant: no. A metaclass can handle more than one class
so you need to pass in an extra object to let it know which one you're working on 13:19
I don't know if rakudo uses this mechanism, but I'm pretty sure SMOP did 13:20
jnthn I suspect it'll come in rather useful when we get to HLL interop style things
moritz (SMOP being a runtime library for MOP stuff written in C, back in the days)
lizmat Regarding S02L1734-41: square brackets? I don't see any square brackets there ? 13:21
jnthn e.g. for the JVM port to provide access to Java classes, for example.
moritz lizmat: the example with square brackets would be my Hash[Array[Recipe]] %book 13:22
lizmat Parametric types are named using square brackets, so: my Hash of Array of Recipe %book; actually means: my Hash:of(Array:of(Recipe)) %book;
is what it says...
so an omission in S02? 13:23
moritz yes
13:23 adu_ joined
moritz jnthn: at your convenience, please take a look at irclog.perlgeek.de/perl6/2013-03-23#i_6622306 I'm kinda stuck with the EXPORT_hash branch 13:24
anant moritz: Do all objects delegate to the same metaclass instance?
moritz all objects of the same type do, in rakudo
13:25 ilbot6 joined
moritz so in rakudo it wouldn't be necessary to pass in the extra argument right now 13:25
so in some sense it's both for future-proving and past-proving :-)
jnthn: (that branch is in the [email@hidden.address] fork) 13:26
13:26 xinming left, xinming joined
anant as that would explain it needing the object as an argument 13:27
[Coke] colomon: I didn't write it down, sorry. 13:29
dalek ecs: aff4d83 | (Elizabeth Mattijsen)++ | S02-bits.pod:
Added omitted square brackets example with parametric typing.
colomon doh
[Coke] you'll see it in the failures when I post today, though.

anant moritz: Rakudo wants that argument ...
moritz yes
but at its current state, it could have been written to not need it, afaict 13:31
anant moritz: which is what was confusing me
moritz anant: I think one motivation was to allow objects with mixins to retain the original type 13:36
jnthn moritz: Note that you can't QAST::WVal something that doesn't already live in an SC
colomon [Coke]: maybe our.t? Lots of changes, and it seems like it's the only one that's changed since the last time I ran make spectest. 13:37
jnthn moritz: Why are you WVal'ing it, ooc? 13:38
colomon jnthn! \o/
moritz jnthn: a type object of a lexical class that I try to import
jnthn moritz: It was actually written as a class? Hmm
moritz jnthn: it looks like this: my class A { }; our sub EXPORT(|) { (A => A).hash }
jnthn moritz: OK, I think I'll have to build the branch. But I'm not sure I have the energy/concentration for it today.
moritz jnthn: ok, no hurry 13:39
jnthn o/ colomon :)
[Coke] colomon: weird. the niecza run is done, I don't see anything new in the diff since yesterday. :( 13:40
jnthn moritz: I do find it very odd that the lexical class would not have had its type object put in an SC, though...
colomon [Coke]: and our.t worked fine when I tried it. :\
[Coke] colomon: there are like 35 failures that are ongoing, btw. 13:41
our.t seems fine, aye.
wonder if it was something that died after generating the "end of test" output. hurm. 13:42
13:42 Chillance joined
colomon [Coke]: yeah, there's the subst.t thing (which I still think is a spec issue, gonna blog about it at some point) and a bunch of misc. failures caused by TimToady++ reworking the return value of if that's it's not clear to me if they are roast bugs or niecza bugs. 13:42
moritz jnthn: I tried also to $*W.add_object every symbol that we import, but that made setting compilation blow up, so I quickly abandoned that approach 13:43
colomon [Coke]: in other words, I've been trying to fix the obvious things, and putting off dealing with the tricky issues until I had more time. :)
moritz jnthn: also it seems that the SC comes from a CompUnit.sc() call. Is it normal to have CompUnits without a SC? 13:44

moritz tadzik: how about "be an awesome module installer"? 15:08
tadzik that's a good one 15:09
Now I need to think of a way to get there
step one: stop hating the code
I have a couple of ideas, and all of them involve turning stuff upside down and breaking backwards compat. 15:10
I could set up a compatibility layer, I guess
moritz or work on a fork 15:12
15:12 Gwyxx joined
tadzik my thoughts keep circling around a git-like thing 15:13
moritz what's the logical successor to panda? babypanda? bear? :-)
git-like in what way?
tadzik so we have a set of independent tools, like panda-build, panda-fetch, panda-test. They can be nice developer tools
early tests show that panda-build can be even faster than ufo && make
pmichaud p6: "panda".succ.say
p6eval rakudo ffe441, niecza v24-35-g5c06e28: OUTPUT«pandb␤»
tadzik then we can have a Mother Tool, called just 'panda', which saves the user the effort of typing all those things to install stuff 15:14
PerlJam "pan db"? it's a bread database ?
:-)
pmichaud it's part of our bread and butter, yes.
tadzik haha
[Coke] AHAHAHAHA.
tadzik and then one of the points is to keep those small tools simple 15:15
so no tight-coupling, no more insanity like Panda::Resources etc
[Coke] So, planetsix.perl.org/ is going away. I am trying out planeteria.org/perl6 as a replacement. I noticed recent changes were not reflecting on the front page. I email the admin, get back: "Congratulations, your perl6 feed broke the system!" 15:16

tadzik: I'm so >.< close to making for-loops eager again
15:19 FROGGS joined
moritz it's just silly to try to make a construct lazy that people don't expect to be lazy 15:19
tadzik moritz: so I'm not the only one?
moritz and then jump through hoops to make it appear to DWYM most of the time
tadzik: not at all
tadzik the point of for, imho, is that it doesn't return results. So I expect side-effects to happen _now_
[Coke] moritz: I don't know if that part of the infrastructure is also going away. Certainly I will blog about it in a feed that appears in sixplanet before it gets shut off.
moritz [Coke]: which time frame are we talking about? 15:20
if it's two weeks or more, I might be able to set up a new system on planet.perl6.org or so 15:21

moritz sink do for @list { ... }
pmichaud: but it's still silly
it violates everybody's expectations except TimToady_'s and mine
and mine only because I implemented sink context
pmichaud well, and mine. :) 15:24
although I'm fine with an eager for also.
tadzik :D
15:25 thou joined
pmichaud ooc, because my brane isn't all here at the moment, do we have use cases for the lazy 'for' ? 15:25
[Coke] Is there a doc on sink context other than the specific mentions in the spec (e.g. "Because C<gather> evaluates its block or statement in sink context")

i'm trying to extract information off of a table. 17:12
there's a value in the table that is 0 on the screen. however when i printed the internal contents of the table. it shows up as not having any value. as a result, the ultimate value is that this cell is blank. i ran the code on this table many times so it is not a spuriously bad web connection
in perl 5 lingo, i tried doing a data dumper. 17:13
maybe i'm dumping the wrong thing ... but how can something show up on the screen and not in the raw table.
i do not have this problem with any of the other contents of the table ...
if it would help and would not be unwelcomed ... i could show brief code and/or the results of the data dumper and/or the raw table ...
i meant the table as it appears on the web 17:14

FROGGS tadzik: you changed panda the last days? how do I set it up on a fresh rakudo? 20:55
tadzik FROGGS: I did not break the original panda, yet
20:55 woolfy left
tadzik FROGGS: there is pandabrew, which is quite cute 20:55
and I'm still working on a new version (mostly a rewrite) of panda, but that's not yet ready 20:56
FROGGS so I just clone that repo and I'm done? do I need to copy modules around?
tadzik pandabrew is ready for testing though. It should improve the panda experience significantly
try it: github.com/tadzik/pandabrew
pandabrew init # brews a new panda 20:57
FROGGS is cloning
tadzik pandabrew env # put that in .bashrc/.zshrc
it automatically detects when you've updated rakudo, and offers to rebuild the installed modules
[Coke] szabgab: updated. will take some time to reflect. 20:58
FROGGS tadzik: you should chmod 0755 it :o)
tadzik ayes, I should 20:59
but well, if you install pandabrew with panda it will 0755 it itself :P
fixed, thanks 21:00
szabgab [Coke] thanks 21:01
FROGGS tadzik: that `pandabrew env` is not quit right 21:03
tadzik how so?
FROGGS if I run `panda`, I get 'pandabrew: command not found'
tadzik uh-oh
well, it assumes pandabrew is installed by panda :F
FROGGS hmmm, chicken&egg problem? 21:04
21:04 rindolf left
tadzik sort of 21:04
[Coke] bootstrap to the rescue! ;) 21:05
tadzik pandabrew improves panda experience, but is not a substitute
pandabrew init bootstraps panda, I guess it could also install itself afterwards
all this could be improved :\ 21:06
labster good day, all you happy perl6 people
FROGGS hi labster 21:07
21:07 szabgab left
FROGGS tadzik: looks like v5 doesn't like panda (or panda doesn't like v5) 21:07
labster tadzik: I sent you a pull request for File::HomeDir (which would improve pandabrew)
FROGGS ===SORRY!===
Could not find NQPP6QRegex in any of: ...
tadzik labster: looking 21:08
FROGGS: ahyes
labster hi FROGGS o/
tadzik FROGGS: well, NQPP@*$J(@! is not in lib anywhere :(
it should probably be installed with Rakudo 21:09
if the module ecosystem wants to use it
labster: looks good, thanks!
[Coke] is nqpp6qregex from the parrot nqp? 21:10
FROGGS [Coke]: right 21:12
[Coke] URK?
masak moritz: I'll have some time to look at tee-two re-views tomorrow ;) thanks for your enthusiasm. 21:13
[Coke] I am surprised to find anything in rakudo-land depending on that.
FROGGS [Coke]: well, v5 is not really in rakudo land 21:14
[Coke] I'm just wondering why use anything from parrot's nqp (which is on the table to get removed from parrot) rather than nqp. 21:15
FROGGS [Coke]: ahh, no 21:17
[Coke]: it is nqp@parrot, not parrot-nqp
[Coke] Carry on, then. ;) 21:18

frdmn if i ord() an character and get "3" as result... what is that? 21:29
geekosaur control-C? 21:30
FROGGS frdmn: it the third character in the ascii table
21:30 skids joined
FROGGS r: say "A".ord 21:30
p6eval rakudo ffe441: OUTPUT«65␤»
FROGGS r: say 65.chr
p6eval rakudo ffe441: OUTPUT«A␤»
frdmn i mean... i have a regexp like: s/\x02|\x09|\x13|\x0f|\x15|\x1f|\x16|\x12|\x03(?:\d{1,2}(?:,\d{1,2})?)?//
i want to include that character in there
FROGGS s/\x02|\x03|\x09|\x13|\x0f|\x15|\x1f|\x16|\x12|\x03(?:\d{1,2}(?:,\d{1,2})?)?// 21:31
frdmn oh i am stupid
i tried \x3
thank your FROGGS
geekosaur \x3 is the same as \x03 21:32
frdmn hmm... it still appears
geekosaur and that looks like mIRC attributes (colors)
and indeed it is control-C
frdmn "101 2 3 101 [...]"
all the color attributes are working fine... and the bold tag 21:33
geekosaur you already have \x03 in that regex 21:34
the original one, that is
frdmn yeah
that is used for colors
\x03
geekosaur yes
so why are you trying to add it again? 21:35
sorear the behavior of \x has changed between 5 and 6. beware.
frdmn im using 5
geekosaur maybe this belongs in #perl then :)
frdmn probably, sorry :/

frdmn i was just still in here because of the auther of ilbot :P 21:36

sorear geekosaur: iirc moritz has told people to come to #perl6 for ilbot help 21:41
geekosaur ah
21:50 adu_ is now known as adu 22:04 xilo left
frdmn not sure if its a perl5 or 6 relevant problem but, when i call a method of a module (IRC::Utils)) i get an "Use of inherited AUTOLOAD for non-method IrcLogBot::strip_color() is deprecated at ilbot2.pl line 34." error 22:07
22:07 thou left
frdmn and the script exits 22:07
can someone help me out there?
22:08 thou joined
masak frdmn: I think you'll have better luck when moritz is awake. right now he's asleep, I think. 22:09
frdmn: try in, hm, about eight hours.
frdmn okay, masak 22:10
i assume he is a european?
diakopter or europan 22:11
FROGGS frdmn: you're assuming right
frdmn i am from germany as well :P
FROGGS frdmn: me too :o)
frdmn \o/
FROGGS beeing in the same timezone is always a plus
diakopter me too, well, 8 generations ago 22:12
FROGGS hehe
frdmn FROGGS: indeed
:P
FROGGS diakopter: well, that's true for your neighbours as well :P
well, at least the chance is pretty gohigh
high

labster It would be nice if S05 actually defined backslash sequences, rather than depend on P5's spec. 23:02
I'm porting something with \l (lc next letter), and that property isn't mentioned at all, as taken out or included. 23:03
huh... it's lowercasing something that matches [a-z]? that's a no-op anyway! 23:11
