msg isBEKaml thanks for the pull request. We've got a release tomorrow (tuesday) so nothing gets merged before that. I'll look at it afterwards. Thanks!
aloha OK. I'll deliver the message.

whiteknight blah, tools/release/auto_release.pl wants to do my text editing in vim, which is a no-go 13:52
try for a few minutes to actually make an edit to the text buffer, fail. Then press Ctrl+C and Alt+F4 until the whole thing goes away and I can get into an editor that I understand 13:53
moritz can't you just make it invoke $EDITOR ?
whiteknight I probably don't have that set up. Plus, it doesn't help me once the script is already running 13:54

brrt1 reading winxed documentation, it strikes me that parrot is remarkably powerful actually 14:38
or, 'cps is actually pretty awesome' 14:39
whiteknight I think so, yes. It's a matter of making sure all that power is exposed through clean interfaces, and implemented efficiently
sometimes we do good. Sometimes we can do better
brrt1 :-) 14:40
14:40 dmalcolm joined
whiteknight wanting to take really cool ideas and give them really great implementations is my biggest motivator for participating in parrot 14:41
brrt mine was 'i want to run perl6 by now'... it has since loosened up a bit to 'parrot itself is pretty awesome' 14:43
whiteknight not a bad loosening :)
Perl6 is extremely ambitious, and if we want it done right we cannot be impatient 14:44
moritz but we cannot wait either 14:45
brrt extremely ambitious indeed
which attracted me in the first place, mind you 14:47
whiteknight Sometimes I suspect it might be too ambitious, and Perl7 will be almost exactly like Perl6 minus the handful of features that are more burden than they are worth :) 14:51
But, you don't know what things are worth until you implement them and test them out
moritz: I think I have a handle on the last remaining threading failures. If we can get that sorted out, and if my GC finalization work tests out, Rakudo might get a few new features this month 14:54
brrt i honestly feel that sometimes this goes way above my head
whiteknight brrt: It takes time and experience. I can tell you that schools usually don't prepare you for "real world" development tasks 15:01
....which incidentally is why GSOC is so valuable 15:05
brrt also, you did read and know i'm not a compsci student, right? :-) 15:12
but really, it is all ... learnable, i guess 15:13
just rather large
benabik Parrot involves some strange concepts from CS. They're not too unapproachable I think. :-) 15:16
whiteknight brrt: What is your major? I'm not compsci either 15:24
brrt biology 15:25
as in, medical moluculair neuro immuno biology 15:26
very few trees and birds, unfortunately :-)
moritz is just a CS minor 15:28
15:31 darbelo joined
brrt whats 'just a' about that 15:44
i read nine's thesis, and i thought it rather impressive
moritz well, I didn't do a bachelor, it was just my secondary subject 15:45
(I don't know if you call that actually a "minor")
brrt ah, i see, what was your primary subject then? 15:46
15:51 alin joined
moritz physics 15:55
(and still is, I'm doing my PHD thesis)
brrt nice 15:59
i started out with physics.. was more or less scared off when people said 'you know whats awesome? physics gets you into finance!'
moritz well, that's an option, not mandatory
brrt i know 16:00
but considering the other options... i don't think i was ever going to be a 'good' physicist really :-)
moritz physics can also get you into basically anything
our prime minister had a PhD in physics
brrt i know 16:01
one reason for my respect for her
PerlJam physics is the sweet spot that everything is based on and has some connection to reality. Math is good too, but it's too easy to lose the connection to reality. :) 16:02
brrt i guess.. life is pretty awesome as well 16:03
:-p
PerlJam brrt: sure, but how those organic molecules interact is all based on the principles of physics! ;)
brrt also true, but complex to a point that physics-as-done-by-humans can't really manage it 16:05
moritz right, you need to get into a different abstraction layer
brrt something that - if i may generalise from personal experience - engineers and physicsists sometimes forget :-) 16:06
anyway, have to run 16:07
hope to catch #parrotsketch today

kjs good evening 20:18
I'm looking for the status of M0. Anyone has some pointers for me?
cotto: ping 20:22
brrt late for parrotsketch, no? 20:26
NotFound kjs: I think there are some doc in the m0 branch
brrt: yes
kjs NotFound: thanks, I'll have a look.
NotFound github.com/parrot/parrot/blob/m0/d...d32_m0.pod 20:27
brrt too bad 20:30
kjs thanks NotFound. Do you know who's working on this?
cotto kjs: poing 20:31
kjs hi cotto
cotto hio kjs
kjs the internet told me you're involved in m0 :-)
cotto I hate that guy, but he's right in this case.
;)
kjs was interested in status, and code.
cotto also, welcome back
kjs thanks :-) 20:32
NotFound brrt: If you have something to report, just enter the channel and write it as a late report, the logs are saved.
cotto the status is that some folks are concurrently working on a spec and two reference implementations 20:33
kjs are the ref impl. in perl?
cotto there's only a perl 5 assembler, but there's a p5 and a C interp
they both currently pass all existing tests
of which there are a healthy chunk 20:34
kjs is this the m0 branch as well?
cotto yes
make m0_tests and m0_c_tests
kjs ok thanks, will have a look
cotto there are a number of important holes in the spec that are being worked through by me, nbrown++, jimmyz++, benabik++ and others 20:35
brrt NotFound: not really, just wanted to see it :-) have read the logs by now
kjs not sure if it's of interest, but there's a Lua bytecode "specification"; there's a manual which explains the lua bytecode format, which may be of interest for implementing a new bytecode format.
cotto yup. I stole a few ideas from it
not too many though, since Lua's philosophy about interacting with C isn't very compatible with m0's 20:36
lua embraces C whereas m0 will use CPS pretty extensively
*C calling conventions
kjs ok. thanks. 20:38
cotto the current list of holes is at gist.github.com/2581153
kjs how do i download m0 branch? Not really familiar with git
can i just click the zip button after selecting the m0 branch on the http interface?
cotto better to have a full git clone 20:39
moritz and then git checkout m0
kjs i have a normal parrot checkout....
cotto then do git checkout -b m0
from svn or git? 20:40
kjs i used git to clone my parrot
moritz then it already has the m0 branch
cotto also, we have a cla from you, don't we?
moritz (unless it's too old, in which case you can do 'git fetch' first)
kjs ok, it switched the branch now 20:41
but I think i still need to do some fetching?
Yes, CLA is there. though I wouldn't start committing...
cotto does docs/pdd/draft/pdd32_m0.pod exist?
if so, you're ready to go 20:42
kjs no.. not there
well not a big deal, i can read online i suppose. just interested in status and how its done 20:43
cotto git pull origin m0
do you want a commit bit now? 20:44
kjs not at the moment, thanks
cotto alright
kjs i'll have to see how much time i have...
but this m0 idea/architecture is very interesting
dalek nxed: 0289de5 | NotFound++ | winxedst2.winxed:
clean a bit IdentifierExpr and FunctionId classes
 20:52
kjs cotto: if i understand correctly, the C interpreter implementation doesn't have a parser/assembler 21:10
cotto kjs: right
kjs is the C implementation going anywhere? 21:11
cotto it's not as important to implement a C assembler right now
definitely
kjs ok
cotto the Perl version is for easier prototyping
the C version is (close) to what the final version will look like
kjs I suppose it's important not to make the same mistake as with IMCC, which is now too tightly glued to parrot guts
cotto and multiple implementations help shake out bugs in the spec 21:12
kjs yeah good point.
cotto which has been happening already
