mberends donri: inventing toy languages on Parrot is exactly why pmichaud++ made the Parrot Compiler Toolkit. 07:53
donri Yea :) 07:54
moritz_ not just toy languages
donri Basing the syntax of a bastardization of Python + LISP + Haskell and some Perl 6, can you imagine 07:55
07:55 shi joined
donri i.imgur.com/6mIxi.png hooray making a vim syntax file before anything else 07:57
mberends I think Perl 6 is doomed to remain a toy language unless we can make at least one implementation that people outside of its developer circle choose to use on a large scale. 07:58
donri Agreed. That day is not doomed to not come, I would think, but might take years. 07:59
mberends aye
tadzik ie eleven years? :) 08:03
mberends a hundred years was (I hope jokingly) posited as the expected lifetime of Perl 6, so we have plenty of wiggle room. The greatest danger is that alternative projects lure away most of the developers before that chosen-by-ousiders implementation is delivered. 08:08
donri You mean in a hundred years it will be obsoleted? 08:11
With the singularity just around the corner I'm not so sure ;) 08:12
08:12 drbean joined
mberends donri: I am sure that a hundred years will see such unimaginable changes in computer architecture that there will be many currently unanticipated new language requirements. 08:13
donri Exactly
08:13 robins is now known as robinsmidsrod
donri Maybe the nanoclouds will run Erlang because of the heavy dependency on communication 08:14
mwahahah

sorear pmurias: niecza's handling of numbers is quite wrong; but there have been more important things to worry about :/ 16:17
pmurias sorear: see the bug 16:18
sorear: it seems the pseudo-inlining pass turns some infix:<=> calls in constants incorrectly
16:19 Psyche^ joined, Psyche^ is now known as Patterner

sorear looks right to me
that's not pseudo-inlining at work - it's special-cased in STD and in the actions

sorear phenny: tell TimToady pmurias and I disagree on what sub infix:<=>($,$a) { say $a }; constant foo = 5; # should do 16:57
phenny sorear: I'll pass that on when TimToady is around.
sorear pmurias: I'm still waiting for a revelation on container removal. As long as post-declared subs can have is rw arguments, I don't think it's feasable. 16:58
pmurias sorear: i don't have a strong opinion on that
17:00 tyatpi_ left
jnthn sorear: Looking at STD and pondering implementation sanity, I agree with your interpretation. 17:00
pmurias sorear: we will need a proper optimalisation framework to do that 17:01
that is something hoopl based rather then adhoc code transformations
sorear nothing whole program can be reasonably done here 17:02
we need something fairly fast and sub-at-a-time, because as soon as a named sub is closed it can potentially be called 17:03
I asked TimToady earlier about sub...sub...sub... BEGIN { eval "sub" ~ (0..9).pick }
totally legit 17:04
pmurias hm?
jnthn hopes that can be relaxed for 6.0.0 17:05
pmurias you mean using eval to generate a sub name?
jnthn pmurias: No, calling subs in the current compilation unit in a BEGIN 17:06
If they're outside of the BEGIN itself, of course.
sorear in general, every time a BEGIN block is seen, all previous subs need to be callable 17:07
that includes implicit BEGINs in use, constant, enum, subset, etc 17:08
jnthn Easy to say, total nuisance to do.
17:09 mkramer1 left
jnthn Guess we'll end up needing to, though. :/ 17:09
17:10 pmurias left, justatheory joined 17:13 alester joined, pmurias joined
pmurias we can do the optimalisations after the last BEGIN 17:15
the optimiser doesn't have to be fast, if the optimiser takes 30sec to make the setting or a commonly used module a few times faster it's worth it
sorear: how can i compile SAFE.pm6 without a setting? 17:18
17:19 cibs joined 17:23 pmurias left 17:25 pmurias joined
sorear pmurias: on-stack replacement is a hard problem 17:26
theoretically, we should wait until the end of the MAIN CHECK to do sensitive optimizations 17:28
I'm not really sure how this should work
it's SAFE.setting, and it *is* a setting 17:29
I think you can just use -Bxxx -C SAFE
pmurias i want to run SAFE.setting with -Bclisp
and i don't want it to load lib/SAFE.setting 17:30
sorear: my understanding is that we will do whole program optimalisations once to program is safe to disk as .nam
sorear you don't need to do anything special - SAFE.setting is special cased to not load itself at NieczaFrontendSTD:497
pmurias in order to support calling subs out of BEGIN we will need to change our model to constructing the program picewise and then serialising it 17:34
17:35 mberends left
pmurias sorear: the psuedo-inliner doesn't handle the insides of infix:</> if i do that 17:37
sorear: would you mind the optimiser being in haskell (so that we don't need to rewrite hoopl) 17:39

sorear pmurias: what do you mean? -C CORE and -C SAFE work fine, they're used in the Makefile 17:53
pmurias: yes, I oppose Haskell componenets. I just got done getting rid of all the Perl 5 components - I'm now quite pleased that the compiler can run in a single process 17:55

plobsing jnthn: is it worth converting Zavolaj to use the new Parrot pointer types (old ones are deprecated), or will nom be bringing larger changes here? 20:24
jnthn Zavolaj is worth updating. 20:27
nom may enable a bunch of stuff but Zavolaj will certainly go on existing beyond it.
(e.g. nom may help Zavolaj be better, but isn't a replacement for it.) 20:28
plobsing but will my changes just get swallowed up in a sea of nom changes in a couple of weeks (a case where I'd classify it as "not worth it")
basically, how much does nom change the inner workings of Zavolaj? 20:29
jnthn Zavolaj mostly works off signature and object introspection. The APIs for those will change little so far as Zavolaj is concerned. 20:31
plobsing OK 20:32
jnthn So ti's certainly worth it.
