Xliff chloekek: I don't know. 08:34
The problem is that the socket needs to get a response from the client before it will send anything. 08:35
That should be done with this line:
await $conn.print: to-json(%handshake-obj, :!pretty);
chloekek That line does finish execution. 08:37
You could add .say to the body of the first whatever block and see if you receive anything.

tyil it's a little used feature, let me grab a link to the docs 10:05
antoniogamiz I have seen you prefer to use that but none of the modules actually specify that part
tyil docs.perl6.org/language/modules#ind...META6.json this describes it as an optional field (because it is)
antoniogamiz oh it looks like we I need for Documentable when the new documentation system comes 10:06
tyil I hoped that comment would spark interest in more people to use an api field in the META6.json, as it makes semantic versioning possible (which, in my opinion, is the most sane versioning scheme we have)
antoniogamiz (which will not be compatible with 1.x.x)
tyil: thanks a lot for mentioning that in the proposed changes, I did not have any idea about it 10:07
tyil App::Assixt has been putting it in META6.jsons for months!
jk, it's not a common thing to see anywhere :p

daxim why does proc::async print to stdout instead of capturing the echo output in the `out` attribute (IO::Pipe type)? 10:58
the sync Proc counterpart does not print 10:59
Xliff Probably because I didn't spec that in the call.
timotimo you have to :out for that to happen
Xliff Yeah.
Hence my entreaty to read the Proc::Async page.
timotimo you expect far too much goodwill from perlmonks, i think 11:00
daxim adding `, :out` to the new: method call does not help, can you show me how it's done right?
jnthn Proc::Async doesn't take a :out; one subscribes to the stdout Supply 11:01
The very first example at doc.perl6.org/type/Proc::Async shows how to do it. 11:02
(I'm glad to see it uses a react block too :))
chloekek Why are ENV and cwd capitalized differently in Proc::Async.start?
11:02 TreyHarris left
timotimo ah, right 11:03
tadzik heh, good question...
daxim how do we combine supply with the code xliff posted? 11:04
Xliff very carefully. It stops being a one-liner, then.
daxim perhaps it's easier to make `shell` async somehow
Xliff For one thing, I'd like to postpone the scheduler until after the command has started. 11:05
I don't think I can do that in "whatever $a.start { }"
jnthn I'd probably have not used $*SCHEDULER directly, but instead Supply.interval(2, 1).tap: { say "in handler..." } 11:06
Xliff jnthn++
jnthn And then it's easy to move into to react block. And better still, stick a `done` in the whenever that handles process termination, and it will automatically turn off that timer too :) 11:07
Xliff Ooh!
jnthn lunch, bbl
Xliff That solves everything.
daxim can you amend the posted code? I want to learn
chloekek Is it ok to begin the signature for BUILD with ::?CLASS:D:? 11:08
Xliff I'll post another comment.
chloekek Afaik it doesn't make sense to call it on the type object.

cygx why is there no parallelism in case of sub map? 12:43
jnthn The sub forms consistently deal in lists, following the 1-arg rule (e.g. sub map(&code, +values)) 12:45
So `map` the sub is always sequential map. 12:46

cygx thanks 12:50
another question: is there a way to set the batch size on a `race for`? 12:51
havint to write `race for @list.race(:batch(42)) {...}` seems sub-optimal...
*having
jnthn Yes, you do it like that; if you don't want to repeat the `race`, then just write `@list.race(:42batch).map: { ... }` 12:52
It's sub-optimal, but otoh the hope is that in the future, needing to set the batch manually would be a lot less common than it is today. 12:53
cygx perhaps a dynamic variable as default for the batch argument coult also work? 12:54
my $*BATCH = 4; race for ...
jnthn That's a bit too leaky 12:55
If anything, we might find a way to sneak in the colonpair to configure `race`, such as `race :batch(42) for ...`
Though not sure how wise that is 12:56

Xliff Yes.
I will run it again to verify.

Let me see if I can get it.

Xliff kay.
The failure exception is "No such symbol "OffendingModule" 14:40
vrurg: The failure exception is 'No such symbol "OffendingModule"'. I expect this is happening because 'require ::("OffendingModule")' hits something that is not being reported and the Failure comes from ::("OffendingModule") not being there because...it wasn't actually loaded. 14:41

anyway yeah wildtrees, you just slap a ^parameterize method on it like this 17:00

jnthn But really...just write a role :)
And yes, you can pass the role values as well as types. 17:01
wildtrees how would I type the values? 17:02
oh its working, just not showing up when I say the role 17:04

JackFly26 What eval issue 17:29
Xliff Dude...that was from back in April... I forgot!
JackFly26 With the parrotvm?
Xliff Maybe
I'd have to check the logs.
JackFly26 That's what I mostly used this for
AlexDaniel JackFly26: yes, it's for those who want to experiment with newest features that will be available in the next language release
JackFly26 Ok nice
Rn I'm just dropping in.
wildtrees can a role have more than one parameter? whats the syntax for that if so 17:30
JackFly26 I decided to try my lang with parser combinators first 17:31
