frostcod very interesting 🙂 09:03
antononcube @frost Thanks! There was an important omission in the introduction -- why functional parsers are used instead of Raku grammars. (Fixed now with a brief remark.) 09:24

[Coke] anyone else seeing github.com/tony-o/perl6-data-dump/issues/40 ? 13:23
tonyo: ^^
timo can you get the value it's actually expecting? 13:24
so for 06-match.t it looks like my $expected = "Match :: (\n made => (Nil),\n pos => 7.Int,\n hash => \{ \},\n from => 4.Int,\n list => [ ],\n orig => \"hello world\".Str,\n)"; 13:25
m: my $expected = "Match :: (\n made => (Nil),\n pos => 7.Int,\n hash => \{ \},\n from => 4.Int,\n list => [ ],\n orig => \"hello world\".Str,\n)"; my $got = "Match :: (\n made => Nil :: (\n ),\n pos => 7.Int,\n hash => \{ },\n from => 4.Int,\n list => [ ],\n orig => \"hello world\".Str,\n)"; say $expected eq $got 13:27
camelia False
timo the Nil has parethesis in one and not the other 13:28
obj.t expects $!public => (Nil) but gets $!public => undefined 13:30
but i couldn't tell you why i can install it successfully and you can't 13:31
do you have a DATA_DUMP env var with stuff in it? 13:37
14:10 zenmov left 14:12 zenmov joined
[Coke] unlikely. One sec 14:45
no env var. 14:46
timo: test would tell me that if it used `is` instead of 'ok $a eq $b` 14:50
working with a local copy... 14:51
The only difference here is the undefined vs. (Nil) 14:53
m: class E { has $.public }; dd E.new; 14:55
camelia E.new(public => Any)
[Coke] wonders why the module is showing that as Nil OR undefined.

[Coke] gist.github.com/coke/d3f749ec9966b...5a82ea2848 - timo 15:08
timo what does that line number point at locally for you? 147 and 133? 15:09
[Coke] it's going to take me some time to golf this, and I'm back at $dayjob. will try to get a golfed set of raku that behaves differently on win vs. *nix 15:16
133 is unchanged, 147 is the try Dump that is paired with '// 'undefined'' 15:18
I removed the try and just called the Dump directly; but the trace isn't inside the Dump call, it's one of the parameters.
trying to dig, I'm now seeing: Cannot resolve caller min(Any:U: ); none of these signatures matches: 15:19
but there's no min() in the lib/ dir.
m: say min(Any)
camelia Inf
[Coke] I'll dig later today 15:21
timo maybe the extreme hammer that is `MVM_COVERAGE_LOG=huge_file.txt MVM_COVERAGE_CONTROL=2 rakudo -I . t/blah.t` can give any kind of insight. it will output one line for every single line that rakudo executes. it will likely be absolutely enormous. 15:59
maybe a lot easier to use the moar remote debugger tbh
antononcube How many people here are interested in answer(s) of this question: > Number of ways of arranging 2n+1 non-attacking semi-queens on a (2n+1) X (2n+1) toroidal board. 16:02
A semi-queen can only move horizontal, vertical and parallel to the main diagonal of the board. Moves parallel to the secondary diagonal are not allowed. 16:03

antononcube Hmm... that blog post would be somewhat late. Meaning, it is 2025 already. 18:14
timo 2025 is allowed to have blog posts as well :P 18:20
..i should post blog 18:21
antononcube It looks like I do not know a fair amount of the properties of the core Raku numerical functions. Meaning, I should prepare a blog post showing different mathematical properties of the number 2025. 18:24
"Math::Sequences" would simplify that post a lot.

SrainUser I'm getting the error: 'use lib' cannot be pre-compiled and thus cannot be used in a module. What do I use instead of 'use lib "."' in imported modules? 20:24
ugexe you set RAKULIB=/foo/bar or pass -I /foo/bar to the raku command 20:29
or `use lib ...` in your top level raku script
SrainUser Where do I set RAKULIB=/foo/bar? on the command line? 20:34
ugexe however way your OS supported. typically one might do `RAKULIB=/foo/bar bin/my-script.raku` to only set it when invoking the script 20:36
to be clear by "set RAKULIB" I mean set the RAKULIB environment variable. how you set your environment variable depends on your OS 20:38
regardless of OS you could just run `raku -I /foo/bar bin/my-script.raku`
SrainUser If I have more than 2 raku files in the same directory, how do they share each each others functions without throwing the error? 21:02
or modules? 21:05
I see. The raku language server was throwing the error. I was able to run the program just fine. 21:09

antononcube Is a there an existing module where a generalization of base can put in? That generalization function is called real-digits; can take non-integer bases. 22:35
For example, this should work : real-digits(π, ϕ, :20length )
I was thinking "Math::Sequences", but seems to be more about integers, etc. 22:36
timo sounds like polymod 22:58
m: say ϕ, π
camelia ===SORRY!=== Error while compiling <tmp>
Undeclared routine:
ϕ used at line 1
timo aw we don't have phi
