sorear is there a meeting going on? 10:05
(hi lizmat)
lizmat hi sorear, yes, quack and hack europe 2012
in paris 10:06
sorear where does one find out about such things? 10:07
lizmat good question… dijkmat was drafted as sponsor… that's how we found out about it :-)
tadzik sorear: getty was talking about it on the YAPC, it was also mentioned in perl weekly iirc 10:08
lizmat also: wendy keeps a list of Perl events and posts them on some of the more local pm lists 10:09
hi tadzik!
10:09 cognominal left
tadzik hello lizmat! \o/ 10:09
sorear so I need to follow perl weekly, huh? 10:10
by "local pm lists" do you mean .nl or near the actual event?
lizmat local geographically, like nl.pm, vlaanderen.pm, groningen.pm, niederrhein.pm lists 10:11
sorear I'm worried that maybe I've missed some random event in *my* area... 10:12
lizmat well, keep following perl weekly, I would guess…

lizmat just found out that you cannot build rakudo star from a directory called 'rakudo*' 10:48
especially if you have a directory "rakudo" next to "rakudo*"
:-)
moritz there hasn't been an advent calendar post today 10:49
does anybody want to chime in? 10:50
lizmat sorry, I have been offline for 2 months or so.. what do you expect from an advent calendar post? 10:52
BTW, has anybody been reading "Uniqueness and Reference Immutability for Safe Parallelism", as mentioned on slashdot some time ago? 10:53
10:54 tokuhiro_ left
lizmat I wonder how the line "our core language and prototype do not allow mutable global variables" throws a spanner in the works if applying to Perl 6 10:55

moritz lizmat: basically a Perl 6 related blog post 11:11
though I guess there are others here that could do it too :-)
tadzik I wonder if I could write a Module::Build plugin-ish thing, to teach cpanm and friends how to install perl 6 modules 11:12
(and where)
11:13 spider-mario joined
felher tadzik: a gernal 'how to install Perl6-Modules' Post would be awesome. There was one 2010, but I don't know how accurate that one still is. :) 11:16
*general
moritz felher: GlitchMr already planned a post on panda this year 11:17
felher moritz: ah, okay. Thnx :)
tadzik: never mind then :)
11:18 cognominal joined
GlitchMr Huh... where is day 8 article? 11:18
moritz GlitchMr: not there yet
which is why I asked if anybody wants to chime in 11:19

GlitchMr Uhmmm... 11:55
I could put my panda article if PerlJam won't insert his article.
But, then we would have problem on 12th. 11:56
The panda article is already 100% done, all I've to do is convert it to WordPress syntax.

as for the 12th, maybe PerlJam wants to take that slot instead, or I'll write something about exceptions
GlitchMr well, ok then 12:41
'Congrats! You have been added to this blog.' 12:42
Thanks
I will add it now
moritz GlitchMr++ 12:44
GlitchMr "This post is super-awesome" 12:47
What?
timotimo sounds like some sort of test post
GlitchMr It's option in "Publish" 12:48
ok, now I can publish it, I guess.
perl6advent.wordpress.com/ 12:49
But that <pre> is on menu...
Perhaps I could fix it...
moritz just remove a bit of indention 12:50
GlitchMr perl6advent.wordpress.com/ 12:51
Well, it's published now
timotimo for me, the pre is in scroll areas
12:52 MayDaniel joined
GlitchMr Yeah, I didn't knew what to do 12:52
timotimo Let’s say you would want to parse INI file. - an INI file or INI files 12:53
using search command - using the search command
When module was installed - when a module 12:54
other than that, it's nice
will there be an article on how to publish your own perl6 modules? maybe a bit of "best practices", directory organisation for projects etc etc? 12:55
GlitchMr heh, masak hasn't found those issues when I've asked him to proofread :-). But I still think he has proofread it nicely.
Now to move things around in mu
timotimo :)

cognominal struggling with liz to get a work rakudo on her humongous 17'' inch macbook 13:30

13:34 Reini left 13:39 sftp joined
lizmat stumped :-( 13:57
src/Perl6/Actions.pm
make: *** [blib/Perl6/Actions.pbc] Segmentation fault: 11
from a fresh rakudo checkout
jnthn Haven't seen/heard about that happening before. 13:58
moritz neither 14:00
lizmat on osx mountain lion with latest xcode 14:01
seeing a lot of warnings like "bind.c:662:77: warning: unused parameter 'lexpad' [-Wunused-parameter] 14:02
...Rakudo_Parameter *param, PMC *lexpad) {
" but cognominal tells me this is normal on gcc-clang
cognominal jnthn, I am working with liz to get highligting from a parse tree. We will have questions to ask you. 14:03
jnthn Well, plus unused parameters aren't likely to cause segfaults.
lizmat $ gcc
i686-apple-darwin11-llvm-gcc-4.2: no input files
cognominal in nqpm how to test if a value is a string? is a sub?
in github.com/cognominal/p6hilite/ I use ugly hacks to get around 14:04
jnthn If you're looking at the parse tree, then you would be going off the names of the rules, I guess?
lizmat $ /Users/liz/rakudo/install/bin/nqp --version
This is nqp version 2012.11.1-10-g785d2fa built on parrot 4.10.0 revision RELEASE_4_10_0
cognominal lizmat, yes we have the same comoiler
right now, I work from a match to get an straight dump, a json dump and a html file 14:05
I need to get lexcical highlingting
jnthn "lexical highlighting"? 14:06
cognominal I have a %rule2docco to match a rule name to a hmtml attribute class name
the value can be either a string or a sub that gives the string 14:07
right now I cheat using arrays. Depending on the type of the array, I will get to the string and the sub
that's top ugly
I would like to test if the value is a sub or a string. 14:08
lizmat basically Perl5's reftype is what I think cognominal wants
14:08 pharoah joined
cognominal jntnh: what I call lexical highlighting is what people call syntax hightlighting. 14:09
jnthn I think there's some isinvokable thing that'll tell you if what you have is something that can be called. 14:10
cognominal I make the distinction because I am able to do dynamic syntax hightlighting on perl6 generated parse tree. Too bad that perl6 code is nqp generated parse trees
jnthn Well, yeah, they have different types of match object.
pharoah I'm new to looking through the perl6 source. Can anyone tell me if uniq is defined in the source for perl6 or if it is taken from perl5 and where I might be able to find it? 14:11
cognominal so I have written code to get the equivalent of a Perl6 .chunks in a nqp match :)
jnthn pharoah: github.com/rakudo/rakudo/blob/nom/...st.pm#L315 is where Rakudo implements it 14:12
pharoah jnthn: great. thank you!!

cognominal jnthn, is_invokable is not mapped from pir to nqp ! 14:33
I suppose I must add the mapping in nqp/src/QAST/Operations.pm 14:34
14:34 SamuraiJack joined
cedrvint_ timotimo: I thought communauty names were exclusive, that's I reserved "Perl 6" 14:34
*that's why
it seems it was useless, so just discard mine :) 14:35
jnthn cognominal: Yeah, that tends to mean nobody decided if it should really exist... :) 14:36
timotimo don't worry about it :)

cognominal jnthn, adding QAST::Operations.add_core_pirop_mapping('is_invokable', 'is_invokable', 'iP', :inlinable(1)); in Operation.nqp would do it? 14:56
jnthn No 14:57
We *never* put the underscores in nqp op names
And the return type is always a register so it must be IP
cognominal ok, will try it
jnthn (exception for underscore rule is to indicate a type, like add_i vs add_n. But never in the middle.)
cognominal don't know where to add it in the file
jnthn Near islist and ishash maybe
cognominal ok, be back. listning the quack talks of the hackandquack 14:58
moritz I've written an advent post on exceptions, and stored it as a draft 15:03

lizmat could it be that rakudo and rakudo-star are interfering with each other ? 16:38
moritz lizmat: they shouldn't, but occasionally it happens anyway
lizmat I guess I will nuke rakudo star and try from scratch then
no change :-( 16:42
src/Perl6/Actions.pm
make: *** [blib/Perl6/Actions.pbc] Segmentation fault: 11
are we sure that nqp / rakudo are currently heatlhy?
jnthn Apparently not on your box :/ 16:45
As I said, nobody else has reported any issues
lizmat: Did you have the same issue with building the last R* release?
lizmat nope 16:46
which leads me to think it was a more recent change in rakudo / nqp that is messing things up for me
I'm going to nuke rakudo from my box now, and start with a fresh rakudo-star just to be sure 16:47
felher lizmat: how many jobs do you run in parallel when compiling?
jnthn lizmat: In your NQP repo, please try reverting 0c08da36 locally and then installing the resulting NQP.
(git checkout master; git revert 0c08da36; make install) 16:48
Then try building Rakudo again.
er, wait
moritz huh, that was just a parrot revision bumpt
lizmat is waiting
jnthn moritz: Yes.
Sorry, I want you to try it with the older Parrot
So we know if the Parrot revision bump is to blame or not. 16:49
lizmat so: assuming a clean machine, what would you like me to do?
16:50 tokuhiro_ left
lizmat get a fresh rakudo checkout, build perl Configure.pl --gen-parrot --gen-nqp 16:50
then revert a commit in nqp subdir? 16:51
jnthn Not quite that
lizmat then make?
jnthn Because it will have built the newer Parrot
moritz let me try to write up the instructions
lizmat moritz++
jnthn yeah, thanks
I as just looking at Configre.pl --help
If you manually clone nqp inside your Rakudo directory after checking it out, then cd nqp and do the git revert I sussgested... 16:52
Then back in Rakudo directory do perl Configure.pl --gen-nqp=master
That may do it 16:53
(then it should build the older Parrot)
moritz lizmat: gist.github.com/4240982
jnthn moritz: The thing that makes me suspect this a bit is that there's hardly any changes in NQP, and none that touch C code.
lizmat a "make distclean" would be enough to start from scratch ?
or shall I clone rakudo fresh from github
moritz lizmat: use git clean -xdf inside the rakudo repo # deletes all files NOT under version control 16:54
then omit the cloning step

Well, awk has "sorta" LTM 20:48
s/"sorta"// 20:49
Just like Perl 6
20:50 bruges joined
masak somehow I doubt awk has LTM "just like Perl 6" :P 20:50
GlitchMr Why?
/a|ab/ matches 'ab' if possible, unlike Perl 5. 20:51
masak yes, as you showed above.
that's neat.
GlitchMr Isn't it LTM?
masak sure, but I doubt it's as widely developed as in Perl 6.
what about more complicated declarative prefixes? what about quantifiers, for example? 20:52
sorear I think what awk is doing might be called "using a real DFA engine"
GlitchMr Because it does use DFA 20:53
masak sorear: oh, then it might actually get quite close, I guess.

it's a small Dancer clone.
quietfanatic I've never seen Dancer, though it looks kinda like Sinatra
So yeah, I'll need a way of accessing a database. Is there a good module for that? 21:12
I saw DBIish sitting around
masak yeah, Dancer is a Sinatra clone :)
I'd recommend DBIish, yes.
look at zblog for how to join them up.
quietfanatic okay 21:13

lue is beginning to feel that the attempt to split up the CORE.setting step will occur in the vicinity of Perl6::World (at least according to the comments next to NQP's HLL::World) 21:20
masak lue: feels like Perl6::World is at an earlier stage than CORE.setting, though.
lue Well, if I go with my plan to include similar functionality to gcc -c and ld (that is, separate these two parts of the process) 21:21
quietfanatic Gah, I've been working under rails so long, whenever I type 'vim' I immediately follow it with ' app/' 21:22
lue I can keep trying to mash together files in src/core and try to find the smallest combination of files that will compile, but, esp. if it comes to rearranging the contents of files, that isn't -Ofun at all. 21:23
jnthn lue: What's your goal exactly? 21:24
I can't help but feel you're setting off on an essentially doomed task...
lue to split the big CORE.setting -> CORE.setting.pir step. (Or rather, make it less memory-intensive) 21:25
jnthn Making it less memory-intensive is certainly desirable. I just don't think trying to split the step up is likely to be very successful. 21:27
21:28 lichtkind joined
masak I have my doubts as well. 21:28
21:28 felher joined
masak and even if you succeed, it's likely to be something of a moving target. 21:28
part of the allure of CORE.setting is that it's actually all in one scope. 21:29
lue Well, my goal ultimately is to make that step feasible. I'm willing to toss out the (admittedly grandiose) "let's replicated gcc -c and ld" idea.
s/replicated/replicate/
jnthn You'd have an easier time reducing memory usage by looking at slimming down data structures. 21:30
Which is where many of the wins over the last year have come from.
masak ooh, that sounds like a feasible idea.
lue Huh. I just looked at the file sizes of CORE.setting and its resultant pir file. I always thought that was taking up all the RAM.
jnthn Granted most of the low hanging fruit has been eaten. OTOH, I shaved 4 or 8 bytes off every Cursor object within the last week... 21:31
diakopter replied to parrot-dev
jnthn lue: The space isn't really consumed by the input and output, but rather by the data structures built while compiling.
21:33 whiteknight joined
lue sounds like working on memory structure slimming would be fun (although requiring knowledge of the code). I'm assuming these data structures are in nqp (at least mostly)? 21:33
jnthn Yes. 21:35
One example of a possible saving: right now, in QAST::Node (the base class) there is a @!children or something like that.
However, not all node types can have children.
There should be some benefit into moving that into a role, which is composed into the various nodes that can have children. 21:36
lue I'm assuming @!children is actually @!array, correct? 21:42

quietfanatic Hm, is it the test that's the problem and not the code then? 22:16
tadzik that might be the only test for that code path
POST params may act funny :) 22:17
and may not (: if źblog works then probably everything's fine
quietfanatic uh...okay, well, I guess I'll go with it then :)
flussence the only reason it fails is because the POST code didn't exist before ;) 22:19
tadzik but it does now, and fails. What to do? /o\ :) 22:21
flussence (actually I'm not sure what's wrong with that particular one, I recall trying to fix it then found out a billion things were broken all the way down to the socket functions)
tadzik I think request() may simply be broken in Bailador::Test
quietfanatic hm.
tadzik it's a bit hand-wavey
flussence IIRC HTTP::Easy will fall over if you try to give it chunked requests too
quietfanatic I can't do without POST though. 22:22
