tetragon My 10.5 build with '-undefined dynamic_lookup' removed but '-fvisibility=hidden' left intact dies off when building the GLUT callbacks (and I did add the '-lparrot' I needed on the no '-fvisibility=hidden' run) 01:03
_do_panic is undefined 01:04
libparrot.dylib is not exporting it (defined internally, though) 01:05
japhb tetragon: I'm not sure what the official way of doing a parrot-friendly panic is. The intent is that panics from libglutcb.so occur when it detects something wrong with Parrot, like the interp that registered a callback has disappeared or something. 01:12
There actually used to be more failure detection code that I cargo culted from the NCI internals, but that stuff was always broken because it needed access to private data structures,
so I just ripped most of it out before submitting the patch.
Something similar should be created (preferably as an exported API) in the future. 01:13

tetragon For testing purposes I added PARROT_API to do_panic in exceptions.c. With that in place, the build and link completes, finding all symbols. 01:24
And yes, the triangle still spins
japhb and really, isn't that the most important thing? 01:30
kid51 When will I be able to run the spinning triangle as my wallpaper?
tetragon I consider building more important than spinning. It can't spin until it builds 01:31
japhb kid51: When I get enough time to wrap the GLUT GameMode extensions.
kid51 Hey, it's spinning for me on both OSX 10.4 and Ubuntu! 01:32
japhb kid51: excellent

tetragon And as expected, removing '-undefined dynamic_lookup' from the compiler flags stopped the (unpatched) readline test from spitting out "strange" errors when faced with editline 01:52

JordanG Hey all, I was wondering if the PIR Language Reference Manual actually exists or if its completely broken 03:16
cotto_home it doesn't appear to exist apart from what's on the wiki 03:23
if you want to learn it, www.parrotcode.org/docs/art/pp001-intro.html is a good starting place
pir?
purl well, pir is a bofh at tufts or www.pir.net or Passive Infra Red or Parrot Intermediate Language (and almost an acronym) or the Price is Right.
cotto_home purl, pir is also www.parrotcode.org/docs/art/pp001-intro.html 03:24
purl okay, cotto_home.
JordanG cotto_home: great, thanks! 03:26
cotto_home JordanG, why do you want to learn it? 03:27
(just out of curiosity) 03:28
JordanG cotto_home: thinking about having a toy langauge i'm working on target parrot
cotto_home it'll be an interesting exercise 03:29
japhb JordanG: You might want to start with PCT ... much gentler than implementing in raw PIR. 03:30
JordanG cotto_home: thats why I'm doing it ;) I started in python but trying to generate python bytecode is a bit of a pain. 03:31
japhb: PCT?
purl it has been said that PCT is a good solution, but heavyweight or the Parrot Compiler Toolkit
JordanG ah
I heard of the compiler toolkit, I wanted to write everything from scratch, just as a learning exercise 03:32
I'll take a closer look at it though 03:33
writing parsers and such is just a BIT of a pain.
japhb JordanG: I look at it as stages, working your way down -- language to implement -> PCT -> PIR -> PASM -> JIT code. You don't want to start by trying to do the JIT yourself. Similarly, trying to do everything in PIR, though nicer than writing C code, can still be a lot of work. So why not make use of the work pmichaud et al have already done? That way you get introduced to the "Parrot way of doing things", get the easy stuff out of the 03:39
way, and then you can later replace any part of that with raw PIR if you so desire.
WTH?
purl WTH is, like, WhatTheHack and happens 28th july 2005 in .nl

That seemed to work a little better.
JordanG japhb: It is a very good argument. 03:40
japhb Anyway, my point was that in my experience, there is an amazing amount of stuff to learn about Parrot. Trying to implement a new language using the low level tools is going to make the learning curve into a cliff. ;-)
JordanG japhb: sometimes climbing cliffs is fun ;) but your right, if there are decent tools out there its silly to reinvent the wheel 03:42
japhb: do you know where any good documentation exists for it? Google results are a little sparse
japhb At least, it's silly if you don't take the time to look over an existing wheel or two first. 03:43
Yes, there is a very good tutorial for it.
looking for URL
Start here: www.parrotblog.org/2008/03/targetin...ot-vm.html
JordanG japhb: just found the one on parrotblog
heh, yeah. Thanks ;) 03:44
japhb The code is all checked into languages/squaak, so that you don't have to retype it yourself if you don't feel like it.
Personally, I find retyping tutorial code can be good for cementing the concepts.
JordanG i tend to agree 03:45
japhb There have been a couple minor improvements to PCT in response to the tutorial author finding some grotty bits; I'm not sure if the tutorial articles were updated to reflect those improvements or not.
(Basically, the tutorial has a couple small workarounds that aren't needed anymore.)
JordanG I'm sure i'll muddle through. Or come back in here and annoy you guys ;) 03:46
japhb Always a pleasure to get someone new working on Parrot!
JordanG japhb: so are you a parrot dev or something? 03:47
03:47 Ademan_ joined
japhb I'm writing the OpenGL bindings for Parrot 03:47
JordanG nice
japhb :-) 03:48
03:49 tetragon joined
JordanG japhb: do you know if the Perl6 and Parrot O'Reilly book is any good? 03:51
i'm browsing the google books preview now, maybe I'll pick it up
japhb JordanG: I've heard it was good, but the dead tree version is considerably out of date.
JordanG japhb: yeah, i was kinda suprised they even had one 03:52
japhb However, O'Reilly released the rights on the Parrot portions to the parrot devs, so those chapters of the book are checked into the tree in docs/book/
JordanG ooh, nice
japhb I dunno if they have been updated fully yet. I've mostly been basing my work on docs/pdds/, where the design docs live. 03:53
JordanG man, somebody needs to update the website and make it more obvious where all this stuff lives. I've been clicking around for like half an hour and didn't find any of this stuff 03:54
i was mostly looking at the examples sections, though 03:55
well, thanks for the help with everything, I'm sure i'll have more questions ;) Its getting lateish here and i'm exhausted, so I'm gonna head out 03:57
japhb g'night
JordanG Oh, one more question, is there like a parrot beginners mailing list i could read to learn from other newbies issues? 04:02
i attempted to google for such a thing, but mostly got results about birds. 04:04

cognominal jonathan++ 13:22
Jonathan I fear not...not this summer, at least. Flights to the US are just too expensive in the summer. 13:23
If there's any autumn conference, I maybe consider it.
cognominal: I hope they don't overlap too much with what you plan on doing - I submitted more than I expect to give so there is some choice for the organizers, anyway.
13:24 mire joined
cognominal when I start parrot in the debugger and do > r languages/perl6/perl6.pbc it dumps (apparently) the perl6 pbc 13:25
this is weird because it works well other wise 13:26

Infinoid what kind of exception should I toss if PackFile_unpack() fails to parse the packfile data? 23:02
I want a sort of "malformed data" exception, but the closest I can find is E_ValueError, which is mainly used by utf8 encoding stuff.
Jonathan Infinoid: If there's nothing appropriate, I suggest adding one. 23:04
That's what I did when there was no good error code to use for role coposition collision exceptions... 23:05
Infinoid two questions: 1. is adding an entry to the exceptions enum all I have to do? 2. do I have to bump the bytecode version for that change? 23:07
(for now I'm just using E_ValueError, plenty of time to change that later)
Jonathan 1. yes, I think so. 2. no, because it doesn't affect the bytecode
Well, easier to have a distinct value for it now maybe? 23:08
Infinoid perhaps.
Jonathan Then at least if people dislike the name you give it or decide it should be one of the existing exceptions, it's an easy renaming job.
Find/Replace
Infinoid I've implemented PackFile->set_string_native and PackFile->get_integer_keyed_str, now its time to start writing tests, to see if the header parsed correctly 23:09
Jonathan And I suspect we want a code for it.
Nice! :-)
Infinoid E_InvalidBytecode? E_MalformedPackFile?
Jonathan I think the second one is better - the first could be confused with trying to execute an unknown opcode or something. 23:10
Infinoid good point, thanks.
Jonathan OK, I need sleep...laterz. 23:12
Infinoid sleep well 23:13
