lizmat japhb__: it was 4:22 am when I did that: because of a storm, our fast ferry across the Irish Sea was cancelled 07:00

is anybody working on unifying nqp's Configure*.pl and Makefiles? 07:36
FROGGS_ moritz: nobody picked that task yet afaik 07:38
lizmat moritz: it's going to be a bumpy ride for the next 3 hours 07:39
FROGGS_ moritz: but you know about that one, right? github.com/perl6/nqp/issues/110 07:40
moritz FROGGS_: yes
07:41 iravan left
FROGGS_ what I would think is that you end up with nqp-moar, nqp-jvm and nqp-parrot, then a wrapper `nqp` that points to your favourite, is able to list the other candidates, and let you switch the favourite 07:42
like perlbrew does
dunno if that fits the needs of that ticket, since it mentions debian-alternatives... which, well, is debian-specific 07:43
moritz well, alternatives can be used on debian 07:44
I guess a simple 'make install-without-nqp-link' or so would be fine for debian, which then takes care of creating the 'nqp' alias
FROGGS_ yeah
perl Configure.pl --but-please-don't-create-the-wrapper-because-I-am-daxim-:o) 07:45
moritz fwiw my plan so far is
1) move the generated files into per-vm directories 07:46
2) unifiy the makefiles
3) unify the Configures
and at each step, make sure it still builds :-)

FROGGS_ ahh yeah, we need the per-vm directories for fudged source files only, right? 07:48
moritz I want to put every VM-specific, generated file into a per-vm dir 07:49
so that if there happen to be name collisions, we are fine

Failed 19/22 subtests
moritz is this the one that succeeds when run on its own? 08:03
FROGGS_ yes
but since it fails always on my box when running with -j4, it should be bisectable
moritz the question is whether to bisect rakudo or t/spec/ 08:04
FROGGS_ I guess nqp+rakudo? 08:05
moritz well, if you find a starting point for the bisect by going back in time in nqp+rakudo, then that's what you need to bisect 08:08

TimToady idly wonders whether ^@num will end up more optimizable than @num.keys 15:05
felher Is there a way to import some Class and giving it a new Name in the Prozess? Something like 'use very::deeply::nested::class::in::some::strange::module::ClassName as MyClassName; MyClassName.new ...". I think I did ask that once and probably did just forget, so sorry for that.
moritz felher: 'constant' can be used for aliasing
felher tests that right away

felher moritz: if you meant to use constant like "constant NewName = foo::bar::OldName", yeah, that works just fine, thanks. :) 15:10
moritz felher: exactly what I meant, yes 15:12
TimToady aliasing is supposed to be built into 'use'
moritz TimToady: with which syntax? 15:13
TimToady do I need to repeat the link I just gave?
moritz erm, no :-)
ah, with use Aliased:name<Original::Name>; 15:14
TimToady though :name is perhaps a bad name for one of two names :) 15:15
TimToady didn't add that...
:was or :really would be clearer to the reader 15:16
felher TimToady: I guess 'the short name' of foo::bar::SomeClass:ver<1.2.3> would be 'SomeClass'? Or foo::bar::SomeClass with just the version stripped? 15:17
TimToady :from is taken, I guess, but the original intent was to use :from for that
japhb__ TimToady: FWIW, :from makes more sense to me as "from this other world" than "from this other name" 15:18
TimToady well, the second component was the from-name, but maybe it's confusing to call that "name" 15:19
PerlJam Why not "use Foo::Bar::Baz:as<Fred>" for aliasing? Is that another of those end-weight things?
TimToady yeah
PerlJam That feels more natural to me, but I can see how it could hide the alias if you're not careful. 15:20
15:20 kaare_ joined
TimToady maybe a cleaner fix would be to reduce :from to :from<name version> and then have some prefix for name that indicates some language other than P6 15:21
or maybe there's just some other thing we're too stupid to think up yet :) 15:22
the prefix could live in package namespace anyway, lang::Java::Foo::Bar::Baz 15:25
or some such
japhb__ Gah, how do I force the Shell-Command submodule in panda to update to the latest commit? (I could just nuke it and clone again, but there has got to be a standard way ...)
TimToady then you could just look in the lang package to see what languages are supported :)

moritz jnthn: are you up for some build and library path discussion? 18:30
FROGGS jnthn: of course beer :o) 18:31
jnthn moritz: sure, let's try )
moritz jnthn: ok, my goal is to be able to build all NQP on all backends within the same source dir 18:32
diakopter moritz: I think the different backends should have different libdirs
moritz jnthn: so I think a good approach is to split off generated files into different directories
diakopter (when installed)
moritz jnthn: which works fine, until I try to invoke NQP from within the source dir, not within the build dir 18:33
jnthn moritz: Which generated files, ooc? 18:34
moritz jnthn: all of them, if possible
jnthn I know that if we try to not build stuff into blib/Perl6 we're gonna hit fun...
Ah, but we're still on NQP at the moment?
moritz yes, NQP
sorry
so I have this branch 'unified-build', which starts to do that for parrot 18:35
diakopter moritz: you don't agree?
moritz diakopter: I agree
./gen/parrot/nqp-p -e 1
"load_bytecode" couldn't find file 'ModuleLoader.pbc'
because ModuleLoader.pbc is in gen/parrot/, not in .
jnthn Right 18:36
It relies on it being in the install location or in .
moritz can I somehow fudge the include path, preferably from within nqp?
jnthn Well, if we toss the fake executable and go to the same approach as the other backends then it's just the --include or --library args (I forget which) to Parrot... 18:37
Not sure if that's throwing the baby out with the bathwater though
moritz or else I could create an ./nqp that is a shell script/batch file that invokes parrot with all those amgical args
jnthn: we could still use the fakexecutable for the installed nqp
jnthn True
18:37 kurahaupo left
jnthn In which case this approach has a decided attraction :) 18:38
Since a similar approach will work just fine for JVM and MoarVM too :) 18:39
dalek p/unified-build: 6059c4a | moritz++ | tools/build/Makefile-Parrot.in:
executable name nqp-p
moritz ok, in this branch, stuff is built in 3rdparty/*, config.stats, dynext/*, gen/parrot/*, src/gen/nqp-config.nqp and src/vm/parrot/* 18:41
*config.status
so I guess src/gen/nqp-config.nqp is the only real problem of those, since all others are parrot specific
jnthn I think that path may just come from the Makefile, though 18:42

moritz newborns just do what they see others do; they don't understand why
masak also, the form of madness that consists of doing the same thing over and expecting different results, is also a form of positive bias.

(repeat N times)
I found that really clever. I also saw it work in practice, really really well. 20:41

masak I think there's a psychological payoff involved. the feeder deposits some amount of imagination into the mind of the child, in the form of the choice of hilarious thing.
