Gus26 It's telling me I need 'use experimental :macros', but even when I add the use statement, it still complains about it. I assume it's a normal use statement, without the quotes, but I tried with and without quotes and it doesn't seem to recognize it. Any thoughts? 00:00
tonyo m: use experimental :macros; 00:01
camelia ( no output )
tonyo what version of raku Gus26
Gus26 I'm trying this
committable6: rakuast %*ENV<RAKUDO_RAKUAST> = 1; my $p = run 'raku', '-e', "use experimental :macros; macro m() { use experimental :macros; quasi { say 'a' } } m;", :out; my $o = $p.out.slurp: :close; say $o;
committable6 Gus26, ¦rakuast: «===SORRY!===␤X::Syntax::Confused at line 2, near "quasi { sa"␤␤»
Gus26 Oops I was trying to put inside the function 00:02
committable6: rakuast %*ENV<RAKUDO_RAKUAST> = 1; my $p = run 'raku', '-e', "use experimental :macros; macro m() { quasi { say 'a' } } m;", :out; my $o = $p.out.slurp: :close; say $o;
committable6 Gus26, gist.github.com/4cbcb7ea0109796ba9...3e5b351bd5
Gus26 Trying what I figure is the simplest possible program that demonstrates the AST functionality is really turned on 00:03
I suppose I could try and instantiate some AST nodes but I need to learn more about the API; I got the sample macro code from one of jnthn's talks 00:04
Also, without the macro, I'm not sure how you insert an AST back into your program 00:07
Ok so that problem was caused by shell quoting, didn't even consider that originally. Now I get the error that it's not recognizing quasi 00:19
committable6: rakuast %*ENV<RAKUDO_RAKUAST> = 1; my $p = run 'raku', '-e', 'use experimental :macros; macro m() { quasi { say "a" } } m();', :out; my $o = $p.out.slurp: :close; say $o;
committable6 Gus26, ¦rakuast: «===SORRY!===␤X::Syntax::Confused at line 2, near "{ quasi { "␤␤»
ugexe does there need to be a semicolon on the } before m() since its on a single line? 00:24
say "a" } }; m(); 00:25
Gus26 As I keep playing with it I feel like there's more shell escaping problems 00:26
ugexe committable6: rakuast %*ENV<RAKUDO_RAKUAST> = 1; my $p = run 'raku', '-e', 'use experimental :macros; macro m() { quasi { say "a" } }; m();', :out; my $o = $p.out.slurp: :close; say $o;
committable6 ugexe, ¦rakuast: «===SORRY!===␤X::Syntax::Confused at line 2, near "{ quasi { "␤␤»
ugexe guess thats not it
Gus26 Even simplifying further, it doesn't work but it's a strange error to me 00:27
committable6: rakuast %*ENV<RAKUDO_RAKUAST> = 1; my $p = run 'raku', '-e', 'macro m { }', :out; my $o = $p.out.slurp: :close; say $o;
committable6 Gus26, ¦rakuast: «===SORRY!===␤X::Syntax::Regex::NullRegex at line 2, near "}"␤␤»
00:27 berber44 left
Gus26 And in an empty quasi and it complains about some character problem 00:27
committable6: rakuast %*ENV<RAKUDO_RAKUAST> = 1; my $p = run 'raku', '-e', 'macro m { quasi { } }', :out; my $o = $p.out.slurp: :close; say $o;
committable6 Gus26, ¦rakuast: «===SORRY!===␤X::Syntax::Regex::UnrecognizedMetachar at line 2, near " quasi { }"␤␤»
Gus26 I have no idea what an UnrecognizedMetachar would be 00:28
I guess a character not allowed inside a macro?
Or is it some shell quoting issue with the curly brace? 00:29
ugexe committable6: rakuast %*ENV<RAKUDO_RAKUAST> = 1; say run('raku', '-e', q|macro m($x) { quasi { {{{$x}}} }; }; m(1);|, :merge).out.slurp(:close); 00:40
committable6 ugexe, ¦rakuast: «===SORRY!===␤Undeclared variable $x␤␤»
Gus26 I don't think it's recognizing the macro keyword
I tried putting back in the use experimental :macros to no effect 00:41
This suggests that there is really something there, but I'm not sure what to do with it: 00:44
committable6: rakuast %*ENV<RAKUDO_RAKUAST> = 1; my $p = run 'raku', '-e', Q^say RakuAST.WHAT^, :out; my $o = $p.out.slurp: :close; say $o;
committable6 Gus26, ¦rakuast: «(RakuAST)␤␤»
ugexe hmm right but i dont think rakuast implies macros 00:45
its just a precursor to better macro support
i also havent kept up with rakuast as much as i should so i might be woefully out of date in my thinking 00:51
Gus26 Hmm, maybe I should make sure the environment variable is actually getting through 00:52
And print the variable from the nested -e block
Also, how can you reference a constructor without calling it?
I'm trying to get the constructor signature
ugexe i suppose there could be many constructors 00:53
Gus26 But RakuAST::Statement.new.signature is trying to call signature on the created object, not the method itself
ugexe ah ignore me then heh
Gus26 I guess it's likely I'm looking for the BUILD method though right?
Isn't it standard practice to not really touch new and put logic in BUILD? 00:54
Probably should have considered this sooner, but the place to see how this works is in the tests 01:05

japhb Is anyone already working on a CBOR implementation (en.wikipedia.org/wiki/CBOR)? I think MUGS will need to switch to that (from JSON) in order to handle really big/rapid game updates, especially including blobs or arrays of native numbers, without spending too much bandwidth transmitting and time (de-)serializing. 01:09
I didn't see anything on modules.raku.org, but I know sometimes people have such things "simmering" in a local repo for quite a while before making them official.
01:12 kvw_5 left
Gus26 Ok, if you're manually building the AST, you don't need the ENV variable, so this works: 01:15
rakuast use MONKEY-SEE-NO-EVAL; my $s = RakuAST::Call::Name.new(name => RakuAST::Name.from-identifier('say'),args => RakuAST::ArgList.new(RakuAST::IntLiteral.new(5))); EVAL($s)
c: rakuast use MONKEY-SEE-NO-EVAL; my $s = RakuAST::Call::Name.new(name => RakuAST::Name.from-identifier('say'),args => RakuAST::ArgList.new(RakuAST::IntLiteral.new(5))); EVAL($s)
committable6 Gus26, ¦rakuast: «5␤»
01:25 brtastic joined, db48x left, db48x joined
Gus26 So the nested call to raku does see the ENV var, but somewhere along the line it's going crazy, and I'm at a loss why 01:26
Still feels like a quoting issue, but I don't see how
Even using the manual AST evaluation in the nested raku causes a weird error 01:28
committable6: rakuast %*ENV<RAKUDO_RAKUAST> = 1; my $p = run 'raku', '-e', Q[my $s = RakuAST::Call::Name.new(name => RakuAST::Name.from-identifier('say'),args => RakuAST::ArgList.new(RakuAST::IntLiteral.new(5))); EVAL($s)], :out; my $o = $p.out.slurp: :close; say $o;
committable6 Gus26, ¦rakuast: «===SORRY!===␤Unknown compilation input 'optimize'␤␤»
Gus26 Also, I guess when you use -e it no longer cares about EVAL
I think -e is doing weird things but I can't find any docs
It's actually looking for a package here: 01:30
committable6: rakuast %*ENV<RAKUDO_RAKUAST> = 1; my $p = run 'raku', '-e', Q[use MONKEY-SEE-NO-EVAL;], :out; my $o = $p.out.slurp: :close; say $o;
committable6 Gus26, gist.github.com/4f221254a9d34b640d...36b159f317
Gus26 Jeez we have been trying way too hard, it just works 01:37
committable6: rakuast use experimental :macros; macro z($str) { quasi { say {{{$str}}}; } }; z("foo");
committable6 Gus26, ¦rakuast: «foo␤»

japhb patrickbkr[m]: I hadn't looked at FlatBuffers (thanks for the pointer) because it wasn't listed in en.wikipedia.org/wiki/Comparison_o...on_formats as being a JSON superset. I wanted something that could do everything that JSON could do (only better in terms of performance and space efficiency) and which could be a valuable core addition to Cro as a default-supported format. 15:46
codesections yeah, that's what I realized/mentioned in the comment. I was surprised by that, but I think I was misunderstanding how lexical scope works 15:47
(in Raku, but also just in general)
japhb FlatBuffers has the downside of needing a schema to parse, IIUC. I also wanted to make sure that the serialization and parsing where schemaless.
MasterDuke protobuf?
codesections (the same effect occurs in js, for example)
El_Che did someone mention protocol buffers? 15:48
(oh MasterDuke just did)
japhb MasterDuke: Also needs a schema to parse. And has one of the most baroque systems for parsing I know of. (I know, I implemented the wire format in Raku back before it was called that.)
MasterDuke ah 15:49
japhb Some other advantages of CBOR is that it is getting picked up in a bunch of IETF specs, has standard bindings for zero-copy (on parse) browser-side typed arrays, and is designed not only to be relatively space efficient, but to be parser-efficient as well, since part of the target audience is constrained/IoT devices. 15:55
All of which are other reasons it looks like a decent fit for adding support to Cro as well. :-) 15:56
japhb wonders if our UDP support is decent enough to support CoAP too .... 15:57
tonyo flatbuffers looks to have flexbuffers 16:02
guifa2 codesections: it's more of at the end of the scope, if the variable doesn't "belong" to anyone else, it'll get frozen. 16:04
m: sub foo ($a is rw) { return { $a + 1 } }; my $x = 0; my &bar = foo $x; say bar; $x++; say bar;

raydiak japhb: fwiw, I was looking at p5's CBOR::PP and it seems extremely short and clean and easy to port to Raku 16:13
japhb tonyo: Hmmm, flexbuffers are at least not schema'd, though it was only by you mentioning it that I even found it -- seems like flexbuffers uses the flatbuffer wire format, but is otherwise not their primary target? 16:16
raydiak: Oooh, good data point.

raydiak however I have no idea of the legalities of creating a derivitive work of a GPLv2 project and relicensing it as artistic 2, or if you'd have to do it as its own separate GPL'd module (or get special permission/relicensed copy from the original author) 16:19
Xliff Can someone help me with regex issues, here: replit.com/@Xliff/MobileBeneficial...#main.raku 16:20
japhb raydiak: CBOR::PP and CBOR::Free appear to be Perl-licensed. CBOR::XS is I think the only GPL-only one? 16:23
raydiak japhb: oh I missed that, just saw the bulk of the license file and missed the first few lines, and saw github said gplv2. looks like its actually dual licensed if I carefully read the top of the license file 16:26
Xliff: apparently I am not human enough to pass the captcha on that site after a few attempts :D 16:27

raydiak got it, looking... 16:44
Xliff Thanks. 16:46
raydiak can you put that together into an actual test that shows how you're initiating the match/parse against the header file and shows the output? 16:48
Xliff ?
raydiak you just define some lexical tokens/rules, but you don't actually use them to parse the file 16:49
Xliff Oh... I didn't finish it off...
Should now be corrected. 16:50
16:53 aluaces left
raydiak looks like you're getting there. in general, I'd suggest wrapping it all in a grammar and using grammar::tracer, if that's something you can do in this environment 16:53
Xliff Well, if you comment out the $<value> rule, I can pick up names,. 16:54
However that's useless.
It looks like <string> isn't working, and I'd like some help figuring out why 16:55
Throwing it all in a grammar and using that is just another way to get a whole lot of nothing. 16:57
Grammar::Tracer would require the whole output to match\ 16:58
s/output/input/
It's why I did this with a regex.
radiakAck! You had it. You needed to remove the my's 17:02
raydiak my bad, assumed this thing would have version control 17:03
Xliff LoL! No 17:05
raydiak I suggest doing that, but against a much shorter test file
Xliff Yes, but the utulity of Grammar::Tracer when used for what really is a line-by-line algorithm is...less than awesome. 17:06
So. As you can see... as soon as I add support for value extaction, things stiop working. 17:09
... or not 17:10
Huh... why does removal of $$ allow the <value> to process?!
Also. Only picks up the decimal, not the hexi... 17:11
!?? 17:12
Now Grammar::Tracer has dissappeared!
raydiak uh...I'll reinstall it 17:13
Xliff Didn't even know Grammar::Tracer was installed by default on repl.it@
s/@/!/
raydiak it's not, I installed it in the shell
it does have zef 17:14
Xliff Ah! Nice trick! radiak++

kybr: to flesh out what Ven_de_Thiel said a bit: the syntax for type conversions is `TargetType(OriginType)` and if OriginType is omitted, it's treated as Any. E.g.: 21:28
m: my $a = Int(); say $a = '42'; say $a.WHAT

codesections (I'm kind of surprised having the coercion doesn't work as the right-hand-side, but that's a tangent) 21:31
