arkiuat | I've been trying to figure out how to set up the same kind of behavior as the perl5 empty diamond operator (reading from files on command-line, if any, or STDIN if not). Learned a lot about sub MAIN and command-line arg processing, but not yet what I set out for. | 06:11 | |
oh, sorry, that's probably more appropriate for #raku-beginner | 06:16 | ||

arkiuat | SmokeMachine, thank you. That works beautifully. I'd forgotten about the special - filename. | 08:56 | |
SmokeMachine | :) | ||
arkiuat | ab5tract_ I'd been messing around with something like sub MAIN (:$f) { given $f { when Str { .say $f.IO.lines }; when Bool { .say $*IN.IO.lines if $f } } } thinking that a -f flag without a filename ought to make it read standard input | 09:00 | |

patrickb | Hi! Is there some convention which filename and format to use for a raku module changelog file? | 09:08 | |
A quick search revealed: metacpan.org/dist/CPAN-Changes/vie...s/Spec.pod and keepachangelog.com/ | 09:09 | ||
They are sadly .... not the same thing. | |||

lizmat | patrickb: as I use App::Mi6, I follow whatever that uses :-) | 09:14 | |
tellable6 | 2023-11-09T21:10:38Z #raku-dev <vrurg> lizmat The only method is nqp::findmethod(HLL::Compiler, 'PERFOR-CHECL').(self). See command_eval in src/Perl6/Compiler.nqp. | ||
arkiuat | ab5tract_ left out the "for"s while typing. Should've pasted it | 09:17 | |
and it turns out that version even works when a filename is provided, once I finished correcting the last of my syntax errors. But the second when clause still doesn't work (because I don't yet understand how raku refers to STDIN internally yet, I guess), and using the - filename is much nicer anyway | 09:21 | ||
patrickb | lizmat: The App::Mi6 changelog looks like CPAN::Changes::Spec. I guess that's what I should go with now. Sooner or later we as a community should make a recommendation and doc it. | 09:23 | |

tellable6 | 2023-10-29T02:15:00Z #raku <Xliff> gfldex That usually stems from when you try to serialize an object that isn't a @, % or Cool-based $ | ||
2023-10-29T02:15:46Z #raku <Xliff> gfldex You'll get that if you do something like: "unit package A; class B { has $.c }; our $c; BEGIN $c = B.new" | |||
2023-10-29T02:16:38Z #raku <Xliff> gfldex That also extends to the contents of any @ or % value you are trying to cache at BEGIN time. | |||

codesections | I'm having trouble detecting a Mu value in NQP. nqp::isnull and nqp::isnull_s both return 0, but dump throws an error saying it's a VMNull. What am I missing here? | 14:56 | |
I'm trying to fix github.com/Raku/nqp/blob/b0bbc4d57...#L612-L619 | 14:57 | ||
which is currently calls tryfindmethod on Mu (i.e., unset) action objects | 14:58 | ||

tonyo | are you just looking for nqp::what($a) ? | 15:16 | |
codesections | Maybe? I tried that, but still couldn't find a way to use it to detect a Mu | 15:17 | |
tonyo | you're looking for the equiv of if Mu ~~ $a ? | ||
codesections | nqp::isnull(nqp::what($a)) still returns 0 for Mu | 15:18 | |
tonyo | m: use nqp; my Mu $a; say nqp::who($a) eq 'Mu' | 15:19 | |
camelia | True | ||
codesections | Yeah; something that returns True (or 1, I guess in NQP) for Mu | 15:20 | |
Oh, I thought that'd be too hacky :D | |||
But maybe that's just how nqp rolls? | |||
tonyo | wonder what ~~ does for type checks under the hood | 15:21 | |
i'd figured it'd be nqp::who($something) eq nqp::who(Mu) | 15:22 | ||
ugexe | github.com/rakudo/rakudo/blob/a9da...od#L37-L44 | ||
checking for a string Mu is done in at least one other spot it looks like | 15:23 | ||
lib/NativeCall.rakumod: if $r.returns.^name ne 'Mu' && !validnctype($r.returns) { # another one | 15:24 | ||
although that one is from a module, not from core | 15:25 | ||
tonyo | github.com/Raku/nqp/blob/b0bbc4d57...lass.t#L29 | 15:27 | |
looks like it might just be .isa | |||
codesections | but everything isa Mu, right? | 15:28 | |
tonyo | only eventually | 15:29 | |
m: use nqp; my Mu $a = Nil; my Int $b; say nqp::callmethod(Mu, "isa", $a); say nqp::callmethod(Mu, "isa", $b) | |||
camelia | True False |
||
tonyo | depends on what order you ask | ||
a pebble is a rock but a rock is not necessarily a pebble | |||
ugexe | m: my int $a; say $a.^name; # why does ^name turn e.g. int to Int? | 15:30 | |
camelia | Int | ||
codesections | I think because int doesn't have a HOW, so $a.HOW($a, name) auto-upgrades to an Int | 15:32 | |
ugexe | m: my uint $a; my UInt $b; say $a.^name; say $b.^name | 15:33 | |
camelia | Int UInt |

codesections | Hmm, neither of the ideas above seem to work either :( | 15:55 | |
nqp::callmethod(Mu, "isa", $a) returns 0 | 15:56 | ||
and nqp::who($actions) eq nqp::who(Mu) throws Cannot stringify object of type BOOTHash | |||
16:07
kjp joined
|
|||
codesections | nqp::who($actions) eq 'Mu' works, though | 16:14 | |
I _guess_ I'll go with that, even though I feel slightly dirty having a hardcoded string there | 16:15 | ||

codesections | Oh, wait, I shouldn't have been using nqp::callmethod with "isa" – I should've used nqp::istype(Mu, $a) | 17:18 | |
I think that might work | |||
