Kaiepi releasable6, status 00:04
releasable6 Kaiepi, Next release will happen when it's ready. 3 blockers. 166 out of 356 commits logged (⚠ 3 warnings)
Kaiepi, Details: gist.github.com/9ecaa05af8d30f49f1...7f6175d507
Kaiepi there are a couple features in the design docs i find interesting 00:05
one's WHENCE and the other's the COMPOSE phaser
the COMPOSE phaser in particular would remove a lot of boilerplate from Trait::Traced
since how it works with types is it mixes in a role to the type's HOW that adds behaviour to composition 00:06

lichtkind lizmat++ 10:02
is there a way to disable inheritance in raku?
lizmat lichtkind: you mean, that it doesn't inherit from Any / Mu ? 10:03
lichtkind like removing keyword is and does
lizmat m: class A { }; dd A.^mro
camelia (A, Any, Mu)
lizmat if you remove "is" and "does", then it would still inherit from Any / Mu 10:04
if you want to disable "is" / "does", you could create local versions of sub trait_mod:<is> and sub trait_mod:<does> 10:05
lichtkind lizmat: to me is important that classes you write are not able to use is or does
10:05 Doc_Holliwould left 10:06 Doc_Holliwood joined
lichtkind lizmat: yes thanks sounds like a solution, I just ponder if its possible to port KBOS to raku 10:06
jnthn lichtkind: Write a MOP module that 1) subclasses Metamodel::ClassHOW and overrides `add_parent` and `add_role` to throw an exception, 2) use the EXPORTHOW mechanism to have it replace the metaclass for the `class` keyword. 10:07
10:07 Doc_Holliwould joined
jnthn The trouble with replacing is/does traits is that they do a lot more than just inheritance :) 10:07
lizmat true 10:08
10:08 holli__ left
lichtkind allright so im stuck with same solution like in perl where you cant inherit kbos classes becasue they life in their own world 10:09
lizmat why wouldn't that work in Raku ?
lichtkind they have their own compilation phase where there resolved to data structures so they never appear as classes
that would work in raku 10:10
just that i cant bring down th thumb of god and forbid inherticance
10:10 holli__ joined
lizmat well, in Perl it's just about messing with a class's @ISA, no? 10:11

samebchase- Hi, What Graph library recommendations do you have for Raku? 10:19

samebchase- Is there any general purpose graph library available? 10:20

samebchase- lizmat: there are a lot of Perl libraries on CPAN that seem promising. Is Inline::Perl or Inline::Python expected to work better? 10:35
10:36 Doc_Holliwood left
lizmat Inline::Perl5 should do the trick for you then, I'd say 10:36
it's the best developed interface to another language that Raku has
samebchase- awesome.
Hopefully someone implements a pure-Raku Graph library someday 😏 10:37

ckc Good Day, all. I am successfully parsing to ASTs- how can I get postorder numbers for all nodes? (e.g., "1+2" as 3 nodes: 1 2 +, numbered: node0 node1 node2). If QAST doesn't provide this, is there an obvious way to derive it from the QAST dd ? I intend to use the postorder numbers as register numbers in compiling to assembly, and this is the 15:09
one missing step.
tellable6 2020-04-18T23:49:28Z #raku <guifa2> ckc: what kind of module are you making with Lingua?
ckc Not sure what "kind of module" means, but I've based my work on Shitov's excellent work. I am successfully parsing arithmetical and boolean expressions (as well as declarations, assignments, if, while; scalars only, I removed hashes and arrays), and accurately evaluating them. What I need is assembly output (Torczon's RISC ILOC). If I can 15:14
convert each node into a register/variable {r0, r1, r2, ..} then I think I've got what I need. I can derive preorder numbers from dd, but postorder is what I need.
samebchase- Given a SetHash like so `my $s = <one two three>.SetHash;` I am struggling to understand why `$s<'one'>` returns False. 15:15
If I have `my $str = 'one'`, how do I use the $str variable to find if that string exists in the SetHash or not 15:16
`$s<$str>` returns False. Or put another way, what can I do to `$str` so that I can use it to index the SetHash using the `<>` notation 15:17
Or am I running into the behaviour or `===`, where two strings 'one' and 'one' are not the same object 15:19
jnthn The `<>` notation is for putting a literal string as the index
$s{'one'} and $s{$str} are for when it's code as the index 15:20
samebchase- okay

samebchase- I have a grammar and during parsing, I want to discard the rest of the file, after the first part of the file has succeeded. What's the best way of achieving this. 15:58
Say I am only interested in parsing the list of imports at the top of the file, and not the rest of the code
What's the best way to do this?
I have verified using Grammar::Tracer that the part I am interested in matches correctly 15:59
Okay, there seems to be a method called Grammar.subparse
16:07 xinming joined
jnthn Yes, subparse is the way to go 16:13
