dalek p/ctmo: b33dc05 | moritz++ | / (3 files):
first shot at removing P6Regex.pir. Diws with "Can only use get_how on a RakudoObject"
 00:03
p/ctmo: aa87ead | jonathan++ | src/Regex/P6Regex/Grammar.pm:
Need to still use the HLL library; was missed when removing the P6Regex PIR file.
p/ctmo: 1eb4e1b | jonathan++ | build/Makefile.in:
Another round of Makefile changes to work towards getting things working again after removing P6Regex.pir.
p/ctmo: 9ace6d6 | jonathan++ | src/Regex/P6Regex/ (2 files):
Need to use block form of packages when there's multiple in a file.
p/ctmo: d014f94 | jonathan++ | src/Regex/P6Regex/Compiler.pm:
Work around a MAIN bug.
p/ctmo: 4460cea | jonathan++ | src/Regex/P6Regex/Compiler.pm:
Move regex compiler init to the right place; now all tests pass that pass in the ctmo branch.
p/ctmo: 9cdb417 | jonathan++ | src/NQP/Actions.pm:
Fix MAIN bug.
p/ctmo: e3036b0 | jonathan++ | src/stage0/ (6 files):

dukeleto sure is quiet in here 04:14
KaeseEs chirps 04:15
dukeleto feels better 04:16
04:16 Khisanth left
KaeseEs i know someone was talking about the GMP bindings gsoc project earlier, has anyone mentioned the GSL bindings project? 04:18
dukeleto KaeseEs: which GSL binding project?
KaeseEs: i think i proposed both of them
KaeseEs: are you interested?
KaeseEs: are you eligible to be a gsoc student?
KaeseEs i'm pretty sure i'm eligible! i'm a junior this year, will be asenior next year 04:19
the one that's on the wiki is for bindings for " Special Function, Random Distributions and Cumulative Distribution Functions (CDFs), which have the simplest function signatures" 04:20
and yeah i'm interested :)
dukeleto KaeseEs: awesome! 04:21
KaeseEs: have you used GSL before?
KaeseEs: i wrote Math::GSL on CPAN and it was a gsoc project 2 years ago
KaeseEs no, mostly i was interested because we did random distributions in my algorithms class about a month ago 04:22
i saw you did math::gsl, was actually perusing the source on cpan to see how it was done :3
dukeleto KaeseEs: beware, it uses SWIG 04:23
KaeseEs: black magic is under the hood
KaeseEs: take a look at src/nci
KaeseEs: most likely, you will need to add some function signatures to src/nci/*.nci, but you might be able to get away without it for the simplest GSL functions
KaeseEs swig autogenerates headers and does marshalling, yes?
dukeleto KaeseEs: it reads C header files and autogenerates XS and Perl glue to call C functions and marshall data 04:24
KaeseEs ah-ha.
dukeleto KaeseEs: somehow, it works most of the time
KaeseEs: lots of people seem to have problems with compiling Math::GSL on windows-ish platforms, tho 04:25
KaeseEs: but that is mostly because their environment is broke
04:25 Khisanth joined
KaeseEs i've got debian in a vm on my laptop, so i think i should be alright build-wise 04:26
KaeseEs fires up vmware and another instance of puttytray 04:27
dukeleto KaeseEs: the Math::GSL test suite will be useful to you, you can basically steal it
KaeseEs: i stole most of it from the actual GSL test suite :)
KaeseEs is parrot cool with perl tests or should i rewrite in pir or something?
dukeleto KaeseEs: i would say that you should start hacking now. do you have a fork of parrot.git on github yet? 04:28
KaeseEs yes
dukeleto KaeseEs: your tests would most likely need to be in PIR
KaeseEs i'm on break this week so i have some tuits to throw at it
dukeleto KaeseEs: but you could write a quick script to convert the Math::GSL perl tests into parrot tests
KaeseEs: good timing!
KaeseEs: i would say, as a first step, try to get access to a single GSL function via PIR, call it and get the return value 04:29
KaeseEs: you will need to use 'dlopen', 'dlfunc' and friends
KaeseEs: read up on those
KaeseEs: if you have a start on the project before you send your gsoc proposal in, that looks *really* good
KaeseEs: also, it will give you a better handle on how to estimate your timelines and deliverables
KaeseEs: the first steps are the hardest, everything gets easier after that 04:30
KaeseEs ok. i'll look at the dlopen manpages maitenant
dukeleto KaeseEs: examples/nci will help you a bunch
KaeseEs heh, my copy of the repo was 89 commits behind
dukeleto KaeseEs: you should basically copy the simplest example in examples/nci and tweak it to do what you want 04:31
KaeseEs: probably examples/nci/ls.pir
KaeseEs googles for a vim syntax file for PIR to make his eyes a little happier 04:32
plobsing KaeseEs: it is in the repo
KaeseEs oh neato 04:33
plobsing editor/*.vim
dukeleto KaeseEs: yes, those will make you much happier
KaeseEs: you should keep your repo up-to-date with "git pull --rebase", commit to a branch and don't commit to master
plobsing also 'make tags-vi' if you haven't already
<3 tags
dukeleto plobsing: i didn't know about that make target! 04:35
plobsing: that should be documented in our new hacking_tips.pod
KaeseEs: github.com/parrot/parrot/blob/mast...rkflow.pod
KaeseEs: any question you have about working with parrot.git is probably answered there
KaeseEs: if not, ask me here or send an email to parrot-dev 04:36
KaeseEs will do!
dukeleto KaeseEs: github.com/parrot/parrot/blob/mast...nology.pod will also be helpful
KaeseEs: excited to see someone hacking on GSL stuff for parrot! I've been wanting to do it for a while, but $life keeps getting in the way
KaeseEs: everybody here is friendly, don't hesitate to ask questions here or on parrot-dev 04:37
KaeseEs: you can mention that you are a prospective GSoC student too
KaeseEs: and if it makes you feel better, mention that I told you to :) 04:38
KaeseEs is #parrotsketch just for meetings btw? i saw it mentioned in the mailing list
dukeleto KaeseEs: yes, every tuesday there is a dev meeting in there
KaeseEs: it is listed on our google calendar on parrot.org
KaeseEs: it is in UTC, so the time changes depending on your timezone+DST (if applicable) 04:39
KaeseEs ah-ha
dukeleto KaeseEs: but i add sms/email reminders to the google calendar to remind me when it is, and I never have to think about that junk
KaeseEs: you can read the irc logs to get a feel for how they go 04:40
KaeseEs: you are of course welcome to attend (everyone is) and be sure to mention you are hacking on gsl bindings
KaeseEs: people will be very happy
KaeseEs do we have some uptake of parrot within scientific computing already? 04:41
i know a ton of eg. bio people are heavy p5 users, didn't know anyone had looked at 6 or other parrot-hosted languages
dukeleto KaeseEs: i guess i am the go-to person for scientific computing + parrot 04:43
KaeseEs: there is a bioperl6 project
KaeseEs oh neato
dukeleto KaeseEs: i know some bio/sci-comp people interested in parrot, but they don't have huge dev resources, so they haven't done much yet
KaeseEs: but they *are* excited
KaeseEs: github.com/cjfields/bioperl6
KaeseEs: i work in the bioinformatics world, i currently hack on solgenomics.net 04:44
KaeseEs oic!
dukeleto KaeseEs: and every line of that site is on github: github.com/solgenomics 04:45
KaeseEs: one of the nice things about being NSF-funded. Every line must me open source, by decree.
s/must me/must be/
KaeseEs so when the GM foods holocaust happens, i should write an angry letter to J. Leto in between shooting plague zombies, is what you're saying :3
does NSF specify BSD style or just something OSI approved 04:46
dukeleto KaeseEs: possibly :)
KaeseEs: i am actually not sure, probably osi-approved. All our stuff is artistic license 2.0 (i.e gpl/perl)
KaeseEs: we don't deal with monsanto or those other evil companies 04:47
cotto I'm hoping to eventually turn Parrot to evil and subvert PaFo, but that's still a ways off.
dukeleto KaeseEs: and mostly we just help facilitate researchers studying public data about plants, we don't sell GMO seeds or any of that evil stuff
cotto: i knew you had alterior motives 04:48
cotto I'm all about open evil.
;)
dukeleto "OSI-approved evil"
KaeseEs is GM for vitamin/mineral fortification feasible yet or is it stuck in the "like foo but bigger!" rut 04:49
dukeleto KaeseEs: i really don't know, I am just a coder pretending to know about biology 04:51
KaeseEs heh
dukeleto cotto: you will be happy to hear that I actually met a bio-coder dude at a conf recently that was excited to hear that I hack on parrot 04:52
plobsing OpenEvil is great. That's how I got my Beowulf cluster of atomic supermen.
dukeleto cotto: i am always taken aback a bit when people actually know stuff about parrot 04:53
cotto: guess i should get used to that...
cotto dukeleto, that's pretty awesome. It'll be even more awesome when it's commonplace.
speaking of which, I really want to find out if my oscon talk gets accepted. 04:54
dukeleto cotto: yeah, me too 04:55
cotto: also, YAPC::NA
cotto: you should go to YAPC::NA
we should have a parrot hackathon there
cotto dukeleto, +1
dukeleto cotto: also, at Open Source Bridge 04:56
cotto: and Linux Fest NW
dukeleto is all about IRL hackathons
so much gets done in a short period 04:57
cotto +1 for each;

Coke whiteknight: pong 16:42
whiteknight has partcl-nqp ever worked?
Coke ... yes.
parrot keeps breaking me. What can I say. 16:43
whiteknight it is relying on some code pathways, some of which are relatively old, which should not have ever worked for you
Coke And yet they did.
whiteknight hence my confusion
I don't think this is a case of "parrot broke it", this shouldn't have ever worked, and now it doesnt 16:44
Coke note that partcl-nqp is just using nqp-rx (and therefore PCT & friends).
whiteknight: (shouldn't have ever worked) - talk to nqp-rx & PCT, then. 16:45
whiteknight these problems aren't in NQP or PCT
Coke Where are they?
What level of the stack? I'm not using anything lower level than PIR, and damn little of that. 16:46
msg cotto - reverse that - while it works either way, it makes more sense to have devel always point to latest and just update latest (and supported if needed.) 16:47
aloha OK. I'll deliver the message.
whiteknight specifically, the code that's a problem is Parrot_pmc_reuse. Autopromotion from Float->TclString is undefined at best 16:48
what worries me the most are the comments "Warning, this should not be called on Object PMCs"
now, we're seeing why
Coke whiteknight: It's not supposed to be going from Float to tclstring. It's supposed to be going from TclFloat to TclString, like it used to. 16:49
whiteknight well, it isn't
Coke Right. because parrot broke something regarding the HLL mapping.
So, rather than give me crap that I'm using some wrong interface...
whiteknight Where is TclFloat defined 16:50
?
"ack -a TclFloat" in the partcl-nqp repo returns no results
Coke *sigh*. I may be conflating the 2 versions. Apologies for ranting. Moment.
yes, there is no TclFloat in partcl-nqp, only partcl. Trying to find the reuse. 16:52
whiteknight the reuse happens automatically inside Float. It's a code path which has obviously never been well tested 16:53
16:53 sigue joined
whiteknight there's no obvious indication that you shouldn't have been using it. 16:53
I'm just surprised that you haven't seen failures in this area until now
Coke to be fair, this is not a recent bug. 16:54
and that would explain why it doesn't impact partcl (which has pmcs for the 3 string/int/float types) 16:55
whiteknight okay. The timeline really isn't important. What's important is that now I know what behavior is expected here, and I can try to implement that
Coke I am wondering why this only happens on the second invocation. 16:56
(and why it depends on the formatting of the tcl code). 16:57
whiteknight The first invocation, the types are different
Coke (presumably it compiles down to different pir)
whiteknight I think it's an Undef being transformed into a Float
I need to trace through it again
in-place morphing to an Object type is going to be a huge pain to implement. It should be in by 3.3 at the latest 16:58

jnthn_ whiteknight: (in-place morphing to an Object type) do you mean PMC => Object that inherits from that PMC? 17:18
whiteknight jnthn: doesn't need to inherit. Just in-place morphing from any built-in PMC type to any Object type 17:19
jnthn_ oh
we have the latter in Rakudo's dynops.
er, wait
whiteknight in src/pmc.c, take a look at Parrot_pmc_reuse and Parrot_pmc_reuse_noinit
jnthn_ I mean, we have the inheritance case in Rakudo's dynops
:)
whiteknight the code does interp->vtables[new_type], and does absolutely no bounds checking 17:20
jnthn_ Though I look forward to killing it in a month or so :)
eww
That sounds...dangerous.
whiteknight I look forward to 6model too, but I need to fix this problem for Coke now. Can't wait for 6model
davidfetter aloha, 6model 17:21
hrm
whiteknight aloha, 6model?
aloha whiteknight: 6model is basically intended to be used from a HLL
whiteknight awesome
davidfetter ah
um, what is it?
whiteknight it's the new meta-object model, inspired by Rakudo's needs in the area
Parrot intends to adopt it, more or less wholesale 17:22
17:22 alin left, ShaneC joined
davidfetter more, or less? 17:23
whiteknight I'm sure there will be some modifications made and plenty of bikeshedding
davidfetter you have to have bikeshedding. totally necessary for any project of note 17:24
whiteknight the bikeshedding is actually the primary objective. 6model is just a nice side-effect
Coke whiteknight: partcl-nqp has no PMCs. (just to clarify your comment on the TT 1886 ticket.) 17:25

Util NEWS says "A statement convert the '.param' PIR systax". Assuming s/systax/syntax/, what does it mean? 17:34
cotto_work It means nobody proofread NEWS. 17:35
whiteknight plobsing made some modifications to the .param syntax in the IMCC grammar 17:36
Util Right :) I mean "what change to .param was made?"
whiteknight: pointer to details?
cotto_work .param can appear anywhere in a sub now
(iirc)
whiteknight now .param can appear anywhere in a function, not just at the very top. This is useful for e.g. params on an exception call and params on callback into a coroutine
Util: I don't know where the details would be. Ask plobsing 17:37
Util cotto_work, whiteknight: thanks!
whiteknight sorry we can't be more helpful!
Util Actually, that was the level of detail I needed 17:38
whiteknight msg NotFound: I would love to have conditional compilation in Winxed. Something like a DEBUG{ ... } block which could be made invisible in a non-debug build would be perfect 17:40
aloha OK. I'll deliver the message.
whiteknight the alternative to built-in DEBUG stuff would be to use a separate preprocessor like M4 17:41
being able to litter your code with debug notes and assertions, and have all those things disappear in a release build would be very handy 17:48
I used to wish for that feature from IMCC a lot. Now, forget IMCC
17:51 dodathome joined
plobsing whiteknight: winxed is quite amenable to CPP 17:51
whiteknight what do you mean by that? 17:52
plobsing the C preprocessor. It works fairly well on javascript and winxed
in case you wanted quick and dirty debug build capability 17:53
whiteknight oh, okay. Yeah there are other solutions I can come up with. I would really love to have something built into Winxed though 17:57
there was some talk at one point of having a Debug PAST node type which disappeared going into POST
I think that was supposed to be part of the tree-optimization work
lucian plobsing: i think that's very evil 17:58
whiteknight how is that more evil than any other type of debug mechanism?
oh, you mean to use the preprocessor. Nevermind
lucian whiteknight: it relies on pre-lexing (or at the very least pre-ast) macros
yeah, that
plobsing lucian: they get a bad rap, but when they're enough, the work great 18:00
lucian plobsing: i think the bad rap is very justified 18:01
plobsing: pre-ansic macros are very dangerous even for simple things 18:04
even ansi c ones are dangerous, and often even for simple things
plobsing they're a feature that is simpler but less powerfull than an alternative, and some people take them too far. Regular expressions are in the same boat. 18:05
lucian plobsing: i blame them for being too powerful and not abstract enough
even scheme macros (which happen during scope analysis i think) scare me a bit 18:06
lucian will brb
plobsing lucian: but those are hygenic! what would you have? hermetically-sealed macros? 18:07

Util In NQP, is there significance to upper/lowercase in the pir:: signatures? 18:18
Such as this: pir::get_hll_global__PPS(...); 18:19
versus this: pir::get_hll_global__PPs(...);
jnthn_ Yes 18:20
S - must come from a register, s = can come from a constant too
iirc
Coke There's a page describing those...

lucian plobsing: they're hygienic, but you still need to expand them to see what's going on 18:26
better is possible
18:26 petdance left
lucian plobsing: www.erights.org/data/irrelevance.html is interesting 18:27
i'd rather have scope checked before any macros, then expansion is much less surprising
although scheme's are the best i've seen so far 18:28
plobsing wait, what do you mean by scope checking? 18:29
lucian plobsing: lexical names scope checking 18:30
lucian 's terminology is crap 18:31
18:32 hudnix left 18:34 hudnix joined
plobsing in plt, conflicting macro names get rewritten, inserting (let ...)s where necessary 18:34
lucian plobsing: racket's macros are better, yes 18:35
plobsing basically, it is auto-gensym
lucian also, expansion for debugging is better
but i still don't think it's quite enough 18:36
plobsing sounds to me like you just don't like macros
lucian plobsing: perhaps :) i don't think they're worth the risks most of the time
but as i said, scheme's are the closest i've seen 18:37
E's macros don't work yet, so it doesn't count 18:38
18:39 minusnine joined
lucian plobsing: for simple things, i rather like D's approach, with version() {} and debug{} blocks 18:40
and static if () {}
playing spore, my idea of a game where programming is important is becoming more clear 18:44

Util jnthn_: Does the MOP provide (at least in theory) an API to control inheritance? If so, would it limited to single inheritance? 23:14
23:16 cotto left
jnthn_ Util: The core doesn't actually know what inheritance is at all. :) 23:17
Util For 6model's core, I agree; is it also true for the MOP itself. 23:18
Util has not read the book :(
s{\\.}{?}
jnthn_ Util: Individual meta-object implementations are free to implement inheritance as they wish. See NQPClassHOW.pm for an example of multiple inheritance, and see www.jnthn.net/papers/2011-nlpw-classes.pdf for an example where single inheritance is implemented.
It's possible to implement any desired MRO also.
NQPClassHOW.pm contains a C3 implementation, but you could just as easily write pre-order or whatever. 23:19
Util But it is the *meta*-object that must implement all this? The MOP has no API to say at runtime something like, "this particular class, let's change the MRO or inheritance tree just for it"? 23:20
jnthn_ I'm a little confused by what you're referring to as "the MOP". 23:21
If you want to change it by class, then you'd need to probably mix in to the meta-object for that class 23:22
And override compute_mro or some such.
Util Thanks! I will point the Python-on-Parrot discussion to this.
jnthn_ Essentially though, the meaning of a class (or role or grammar or whatever) is defined by its meta-object. 23:23

p/ctmo: 2acf542 | jonathan++ | / (2 files):
Eliminate HLL.pir. Now we're down to just one library that is overall PIR-compiled; the rest is NQP-compiled. We'll keep Regex.pbc fully in PIR for the foreseeable future, and everything else will trend towards its last remaining bits of PIR becoming NQP.
