MikeFair Heya Parrot! 02:07
02:10 rurban_mobile joined
sorear hello MikeFair. 02:13
MikeFair continues on his quest for compilation and execution of his language using the new nqp. :) 02:15
It seems like "make" instead of parrot setup.pir is the tool of choice... in the two projects I've looked at (perl6 and Partcl-nqp) 02:16
benabik The general choices seem to be Makefile or setup.winxed 02:17
MikeFair benabik: unfortuantely I started with mk_language_shell.pl 02:19
benabik mk_language_shell needs some love.
There's nothing _wrong_ with a setup.pir
Other than hand-writing PIR.
MikeFair Well my problem seems to be that I need to call NQP's version of Compiler.new() and friends, but I can't seem to find a good hokk that works into making that happen 02:20
err hook
I'm sure this is just my ignorance I'm struggling with
I like the parrot setup.pir just fine for my purposes, I just can't seem to get a working build out of it. :) 02:21
I was told that my problem, based on the error of not being able to find a parse function, was that the compiler didn't get registered 02:22
So what I'm not sure about is how to go about getting the right things in the right places to make it all work 02:26
I'm not married to NQP either, it just seemed more supported than winxed for my purposes 02:29
I think I see the problem... 02:37
.local pmc hllns, parrotns, imports 02:38
hllns = get_hll_namespace
parrotns = get_root_namespace ['parrot']
imports = split ' ', 'PAST PCT HLL Regex Hash'
parrotns.'export_to'(hllns, imports)
benabik ... Can anyone write a calm response to zhuomingliang on gh818? I keep coming to "let's not have this argument _again_"
MikeFair in all the .pm files I had to add use NQPHLL;
benabik MikeFair: Are you trying to use parrot-nqp or new nqp? 02:39
MikeFair nqp
parrot-nqp seems to have some challenges in certain areas that I thought should work but are causing problems. 02:40
benabik mk_language_shell is based on parrot-nqp, and I would expect many subtle issues trying to just s/parrot-nqp/nqp/ in the result. 02:41
MikeFair I was having a hard time telling the difference between my ignorance/misunderstanding/mistakes and the limitations of parrot-nqp
benabik: I used a symlink
benabik Symlinked nqp to parrot-nqp?!?
Even vice-versa seems like quite a bad idea. 02:42
MikeFair other way around, but yeah, moved parrot-nqp to parrot-nqp.orig
benabik `ln -s nqp parrot-nqp`?
MikeFair Well I watched parrot setup.pirs execution, and the command line is the right command line
benabik: Yes
It builds
benabik That's... not a good idea. There are differences between the two and I would expect many subtle issues.
MikeFair benabik: I had to rebuild parrot and nqp to make sure they were aligned 02:43
benabik Simply replacing parrot-nqp with the new nqp is not the solution.
MikeFair benabik: I don't exactly see why not? 02:44
benabik: the nqp excutables take the .pms and output them to .pir
parrot doesn't see or even care what's in those .pms
benabik nqp takes .pm and outputs .pir that requires 6model. 02:45
I suppose the things we have written in nqp-rx are already compiled by that point...
MikeFair 6model are is a language or pbc's that parrot can load? 02:46
benabik It just feels wrong.
parrot-nqp is not nqp. parrot-nqp is nqp-rx
Which is a generation behind.
MikeFair Yes, I do need to change my source code 02:47
Which I've been doing
benabik Doing language development in nqp is fine, but I would suggest that making things that expect parrot-nqp run in nqp is error-prone.
MikeFair benabik: I'm doing a full textual replacement of my source in straight nqp
benabik: I have like ten meaningful lines of code 02:48
I'm just working with the language shell atm
and even with that I'm primarily focused on the Grammar.pm parser part more than anything else
:)
benabik: I agree it feels wrong :) 02:49
benabik: My other option was to drop parrot entirely and just do the whole thing straight in rakudo
But I'd like to get to the point where I'm working on parrot's internasl
I'd like to try my hand eventually and trying out using a message queue model internal to Parrot (where rather than pirops being sequential in memory, the ParrotVM would be treated like a service consuming the pirops from the queued pipeline. Eventaully this is part of an end game I have to make a sane execution model for running parrot on GPU architectures). 02:53
(Namespaces, classes, and such would all have their own queues and a reference to an execution context would get passed around through the queues) 02:54
benabik Sounds interesting. 03:13
MikeFair benabik: So what do you think? Can this be done? I only did a symlink because I didn't know how to get parrot setup.pir to execute the nqp command instead. :)
benabik comments on gh818 and hopes that he kept most of his frustration out of it. 03:14
MikeFair benabik: I totally see what you're saying now if I was trying to build other langauges that expected nqp-rx then I just broke every one of those language compilations . :)
benabik++
benabik Getting setup.pir to run nqp would require mucking around with distutils. 03:15
I seem to remember adding a new phase wasn't too difficult...
MikeFair benabik: Wisdom for us all that we may acquire his patience
benabik: Actually, yeah, I remember seeing that distutils was straight in the middle of it 03:16
benabik Adding winded to distutils: github.com/Whiteknight/Rosella/blo...ils.winxed
MikeFair benabik: What do I do with that? 03:18
replace the distutils.pir in my library?
or add it somewhere and rebuild parrot
benabik MikeFair: No. That calls distutils functions to extend it.
You (or someone else) could use it as the basis of something similar for nqp. (rather than nqp-rx) 03:19
MikeFair So download it, compile it and run it?
benabik MikeFair: This is how I used it in PACT: github.com/parrot/PACT/blob/master...winxed#L69 03:20
That assumes Rosella is installed in the system.
MikeFair Which it is not atm :) 03:21
benabik It's probably not directly useful to you as-is, but it might point the way towards getting distutils to use nqp.
MikeFair Coke has managed to get Partcl to build with NQP and so I was trying to replicate the work he did
sorear Was there not at one point a distutils that used setup.nqp ? 03:22
opbots trust MikeFair
slavorg Ok
MikeFair sorear: The distutils library says I can use a setup.nqp but I couldn't make it work
benabik I recall setup.nqp using distutls, but not really vice-versa. 03:23
MikeFair Wow, thanks :)
any idea what this is? 03:26
github.com/ekiru/tree-optimization.../setup.nqp
sorear ekiru = tcurtis = tylercurtis, one of our past GSoC students 03:27
benabik That is an NQP script calling distutils.
sorear tree-optimization was an attempt to create a generic optimization framework for PAST
MikeFair benabik: Right, so that won't really help me because what I need is the distutils using nqp part
sorear like so many things we've built, it never really got used :(
MikeFair thinks he'll just type it out by hand and put it in a shell script to compile everything 03:28
It's 6 files and they take like 1/2 a second to build and I only want it for testing purposes 03:29
I'll absorb more about the build processes as I go along
ok 04:35
so think I'm really close now
here's what I'm getting
"load_bytecode" couldn't find file 'NQPHLL.pbc'
That file is in ~/local/lib/parrot/4.7.0-devel/languages/nqp/lib 04:36
but that lib directory does not seem to be in the load path
any suggestions? 04:38
Woohoo it built! 04:50
But it can it "say" anything?
nope:Method 'pasttype' not found for invocant of class 'QAST::Op'
benabik I've only found "It compiles" to have any relation to "does it work" in very strongly typed languages like Haskell. 04:51
And even then it's not very strongly correlated.
MikeFair benabik: hehe 05:00
benabik: yeah, it seems that I'm now back to my early days of assembly when compilation and build meant almost nothng 05:01
benabik For dynamic languages, "it compiles" just means you didn't screw up the syntax too badly. The compiler doesn't care if you're trying to do something non-sensical.
The runtime OTOH 05:02
MikeFair yep
It seems that I've done something that registers say and print as viable parseable statements that are supposed to call "something" but that either go into some recursive loop or otherwise just disapear into and infinite blocking state when called 05:03
Yep, maximum recursion depth exceeded :) 05:11
Wel, it seems to be parsing, but I'm still getting a strange error 05:24
I put simply <integer> in TOP 05:25
and now get: Syntax error at line 2, near "\\n"
anytime I type an integer
If I type something "not an integer" then I get a parse error! :)
It's progress!! 05:26

brrt hi #parrot, i need your help once more 11:47
moritz I can try :-) 11:48
brrt oh, moritz, i need your help for another thing entirely 11:52
but my first and foremost problem
is that, when specifying parrot applications to run via the psgi handler
the actual script that should be run is Not Well Defined
case in point, i use an uri to specify the script 11:53
with the following structure: <compiler>://<script>/<class, optional, slashes are namespaces>#<routine, optional> 11:54
thus, if I have a script called foo.p6, which has a class called MyPsgiHanlder, and a routine called accept
it would be perl6://foo.p6/MyApp/MyPsgiHandler#accept 11:55
similarly for an error handler
perl6:://foo.p6/MyApp/MyPsgiHandler#onerror
but, where is foo.p6? 11:56
if you say 'server document root local', then fine, but it means i cannot put files anywhere but in the document root
which means $documentroot/somedirectory/foo.p6 would never work 11:57
wait.... this is a resolvable problem
i add yet another option
called ParrotApplicationDirectory
hmm no that is still not ideal
anyway, summarising 11:58
i use an uri scheme for specifying the langauge, script, class and routine 11:59
but using the hostname for the script component is Not Ideal 12:00
moritz yet another option sounds quite sensible to me
and have it default to the document root
brrt (virtual) server document root?
moritz erm, what other document roots are there? 12:01
brrt hmm.. not many
moritz but yes, I think that's what I mean
brrt its just, i had put it in <directory> statements earlier... hmnmmmm 12:05
bascially if it is in 'server' context, use document root 12:06
if in <directory> context, use directory specified
oh, and moritz, i get the 'raw parrot cannot load rakudo' problem 12:35
likely scenaroi, i must link something before i can load rakudo with load_language 12:36
moritz brrt: I can look into it, but I'm not sure I'll know how to fix it 12:42
brrt well, yeah, it would be nice to know in general :-) otherwise, i have to inspect the rakudo build process by hand 12:44
which i can, but don't in general
and haven't, and i was hoping you'd know
Coke yawns. 12:46
moritz brrt: a load_language 'perl6' just succeeded for me 12:47
brrt: after having rakudo installed, that is 12:48
brrt: what else do you need?
brrt ... lets see if i can make that work
moritz as in, it didn't throw any exception :-)
brrt i recall that being broken
no you 'should' have seen a segfault :-)
moritz yes, I recall that too 12:49
but now it works, by magic :-)
brrt sometimes magic is good
darn, i appear not to have perl6 on this box 12:50
wait, i'll get back to that
moritz ah 12:53
$P0 = compreg 'perl6'
$P0.'eval'('say 42')
brrt wait wait!
moritz Null PMC access in find_method('eval')
brrt you /should/ call load_language('perl6') first 12:54
moritz yes, I did
what's the way to register a compiler with parrot so that compreg will find it?
brrt ..... 12:55
hmm
load_language :-p
no, really, its compreg($S0, $P0)
but
thats what load_language is /supposed/ to do
moritz wait, how? 12:56
12:56 PacoAir joined
moritz load_language looks for a file named language.pbc 12:56
brrt well, i can't claim to know that
probably in its init function?
or load
moritz so the init function has to call compreg(S, P), so that compreg(P, S) will find it? 12:57
brrt as far as i know, yes
will have to check the documentaiton
moritz yes, that's how it should work 12:59
brrt it is somewhat of a lack in my understanding 13:00
whiteknight not here?
Coke moritz: yes, that's true.
in nqp, you get this by... 13:01
brrt nqp doesn't play nice with that at all
Coke github.com/partcl/partcl-nqp/blob/...cl.pm#L100
brrt (it can do it, but doesn't, no idea why) 13:02
13:02 PacoAir joined
moritz Coke: thanks, I'll try that in rakudo 13:03
Coke Oh, I thought rakudo already had all this figured out and that that was where this was cribbed from. ;) 13:09
moritz Coke: it probably was, in pre-nom days 13:11
.oO( nom ate it! )
 13:12
but it doesn't work
compreg still returns NULL
and no compreg in the generated .pir code 13:13
oh, and I know why 13:14
because it calls compreg at the time that you call $compiler.language($name)
but it doesn't generate code that calls compreg
