Tweaks on Parameter.new

  - added "exclude" parameter
   If set to a True value, then the parameter will be excluded from dispatch
   (aka, it will introduce a ";;" in the Signature of which the Parameter is
   to be a part)
... (5 more lines)		 11:45
lucasb lizmat: Don't you think kebab-case looks better for those named parameters? :) $is-copy, :$is-rw, :$is-raw 11:57
11:57 pmurias left
lizmat yeah, was thinking about that.. 11:57
timotimo why not "offbYoNecAmelcAse"? 11:58
jnthn I think exclude isn't really clear what it's excluding it from. I'd probably just have a :multi-invocant that defaults to true and if you want to make it off you'd :!multi-invocant, which reads rather more nicely 11:59
lizmat tImotImo: not sure what you mean :-) 12:02
timotimo to make it more natural to people coming from other programming languages, maybe we can find out what "double semicolon" means in hebrew
lucasb haha, the PHP meme
lizmat meanwhile it seems I borked some nativecall tests :-(
lucasb ah, right, Paamayim Nekudotayim :) 12:04
timotimo well, that's double colon
lucasb I really thought this was the name of a person :)
timotimo class X::Steve is Exception { method message { "what kind of rapping name is steve" } }
Geth rakudo: e116f3adf7 | (Elizabeth Mattijsen)++ | src/core/Parameter.pm6
More Parameter.new tweaks

  - kebab-case: is_copy -> is-copy, is_raw -> is-raw, is_rw -> is-rw
  - rename: exclude to multi-invocant and reverse the default
   use :!multi-invocant to *not* have the multi-invocant flag set		 12:06

lizmat check :-) was looking for trait_mod 13:21
timotimo ah
lizmat ah, I probably need to create a BUILD_LEAST_DERIVED as well for Parameter\ 13:22
timotimo it doesn't get one from Mu?
lizmat it probably does, but it's not doing the right thing, I think
it probably runs BUILD again 13:25
yup, providing an empty BUILD_LEAST_DERIVED fixes the problem 13:26
timotimo but what does it do wrong? %) 13:27
lizmat it runs BUILD again without any parameters, losing the type info

cfa on the commit itself?
AlexDaniel no, on github.com/rakudo/rakudo/issues/2601
cfa oh, derp 17:55
missed your second link
AlexDaniel hmm, I wonder what is causing it 17:56
cfa: a golf of the issue can help, I think 17:57
lizmat I think it decided too quickly it can merge blocks, and therefore lose significantly different $_'s
cfa AlexDaniel: yeah, i'll take a look inside at the tests 17:58
AlexDaniel yes, but where exactly? The ticket is about `{ } for …` but no such construct in the source of the module
cfa okay, here's what's happening in the encoding module: 18:06
my $rx = rx/<[a..z]>/; 'abc'.comb.map({ if $rx { 'yes' } else { 'no' } });
that's (no no no) in HEAD, (yes yes yes) in 2018.12

AlexDaniel cfa: so it's jnthn's work for sure, but I'm a bit surprised that the whole module bisected to 541a4f1628e but that snippet bisected to an earlier commit eb3917c260b 18:17

patrickb I now have implemented some logic to determine the paths to /share/perl6/ and /share/nqp/ at runtime. They are required in the ModuleLoader (to determine the search paths, I think this happens very early on) and in RepositoryRegistry (setting the repository locations). Now I don't want to copy that logic. Where would be a good place/time to do them? Where would I stash the results? 20:09

patrickb I somehow got it to work by putting the code at the top in main.nqp (that's about as early as possible :-P) and using bindhllsym. 20:54
japhb patrickb: Does it slow down startup measurably? We'd like to avoid significant extra startup work where we can. That said, maybe take a look at rakudo/src/core/VM.pm6 ? 21:24
patrickb I haven't measured yet. But I guess it's a price we have to pay. 21:25
