Xliff Could someone take a quick look at https://github.com/Xliff/p6-Amazon-AWS-EC2/blob/DescribeImageAttribute/lib/Amazon/AWS/EC2/Tests/DescribeImageAttribute.pm600:29
And tell me why uncommenting the use statement on line 5 results in the require statement on line 20 to return Nil rather than a ClassHOW?00:29

Xliff vrurg: How can I tell if I've already loaded a module?02:20
vrurg Xliff: try checking for ::('Module::Name')02:20
Xliff Yeah. Am doing that, and it comes out as Nil02:21
But it's a thought. *sigh*02:21
m: my $r = ::('Test'); $r.^name.say02:22

Perl6::Metamodel::ModuleHOW02:22
That what it should be.02:22
Xliff vrurg++02:23
vrurg And if for any reason a module is not loaded you get Failure as a result.02:23
Xliff I'll rework things and see if that helps.02:23
vrurg Xliff: good luck!02:23
vrurg leaves.02:23
vrurg o/02:23
Xliff vrurg: So do you know why "(require ::('Module::Name'))" would return Nil?02:24
Oh. Well. o/02:24
vrurg Ok. :)02:24
You wrapped it in try {} – that's why. It masks away the problem.02:24
https://docs.perl6.org/language/modules#index-entry-require02:25
Xliff No. Those weren't curlies02:26
vrurg It doesn't matter.02:26
Xliff So remove the try?02:26
vrurg Curly braces are often optional. See BEGIN say "ok"; and BEGIN { say "ok" }02:26
Xliff So... "my $c; try { $c = require ::("Module::Name") }"02:27
??02:27
vrurg Depends on what you need. Basically, if it returns nil – it's a sign of a problem. Then if you check the return of ::('module') and get Failure – this is a problem.02:28
Xliff Yeah. Getting that . It's finding the root problem thats...well... the problem! :)02:28
vrurg ok, really time to go. Try the docs, they're pretty good on this subject.02:28

Woodi hallo #perl6 :)14:33
yoleaux 28 Jun 2019 22:06Z <sena_kun> Woodi: I re-did the module, now it parses all RFC examples, still exports hashes, but the structure is more complex. will update documentation tomorrow and do a PR14:33
sena_kun o/14:33
Woodi sena_kun: merged and seems working :)14:33
sena_kun \o/14:33
thanks!14:33
Woodi sena_kun: loots of work you have done !14:33
sena_kun wasn't worse than patching ASN::META to get a proper support of OCTET STRING type. :)14:35
Woodi sena_kun: if you want to do more work on it you can just make yourself maintainer and point ecosystem to your repo14:36
but if not then that's ok too14:37
sena_kun Woodi, I think now it does everything that I'd expect from "Text::LDIF" name, hence I bumped its version to 1.0. Maybe I'd add some serializer, but it can as well live in some other place.14:38
Woodi, if you insist on passing the maintainence to me, I don't mind too much, but I had no intention of "stealing" the module, just wanted it to support more features.14:39

→ AlexDaniel joined14:42
Woodi sena_kun: ok, then if you do more work then just change location in ecosystem to your repo for easy of work. then if you want to have less modules you maintain I voluntire to take it back14:54
sena_kun Woodi, sure, will do so if something other will be needed.14:55

TreyHarris I don't see how that gives the right answer, I don't see a special case that rounds when the denominator gets too large nor do I see where the Euler identity is handled trigonometrically, which can give the correct answer numerically. It looks like it's doing algebra. It's mathemagical ;-)18:23
