and I have no idea how to use ipmi

wahnberger moritz: thx!
lizmat wonders if reseating things that haven't been soldered, might help 09:27

kawaii I'm trying to `.round` the `%stats{$inc}` and `%stats{$dec}` here so that I don't end up with floats (I need Ints), but keep being told they're immutable, any ideas why? www.irccloud.com/pastebin/TONa1gQ0/ 15:48
(the `if $inc` and `if $dec` are there purely because they can sometimes (rarely) be `(Any)`, which is valid but causes issues) 15:49

evalable6 False

lizmat kawaii: I guess I need more context?
kawaii lizmat: I'll provide a gist/example shortly 15:52
lizmat okido 15:53
kawaii `%stats` is a hash containing values that look like this: `{attack => 50, defence => 50, hp => 50, special-attack => 50, special-defence => 50, speed => 50}`
`$nature` contains a hash too, with keys like `increased-stat`
www.irccloud.com/pastebin/ch0D3nP4/ 15:54
I'm just not sure why these keys in this hash are immutable 15:55
If I remove the `.round` from `%stats{$inc}.round *= 1.1 if $inc;` it works but I get floats in the two keys we modified 15:57

japhb kawaii: Where's your repo? (I did github.com/japhb/RPG-Base and a few system-specific variations for e.g. PFRPG, so your question caught my eye)
kawaii japhb: it's github.com/kawaii/p6-pokeapi but I still need to push this code to it 16:07
one moment
japhb: so if you use this example script - github.com/kawaii/p6-pokeapi/blob/...eration.p6 it uses my :Test datasource, so no need for a database 16:09
usage: `perl6 -I lib/ examples/full-generation.p6`

^ the specific method
16:12 aindilis left
japhb kawaii: The problem with that method is that you want .round on the right, not the left. (.round does not produce an 'lvalue', which is a value that can appear on the left side of an assignment.) 16:12
raschipi You you'll need parens. 16:13
japhb So you'll probably need to longhand it a bit -- %stats{$inc} = (%stats{$inc} * 1.1).round if $inc.

17:45 Manifest0 left
raschipi It would be easy if you run just normal normal processes but started multiple workers in Perl6 to wait for them. 17:46
xinming raschipi: But there are over 20, running them all causes cpu to be bloated 17:48
sena_kun m: react { my $batch-size = $*KERNEL.cpu-cores; my @queue = eager 0..10; sub do-one { with @queue.shift -> $el { sleep rand; say $el; do-one } }; do-one for ^$batch-size; }

xinming So, I'm thinking wether it's possible to control the size.
sena_kun but in do-one you are running a Proc::Async, and inside of the same sub then you can do `whenever $proc.ready`, `whenever $proc.start { (call do-one here) }` 17:49
xinming I need to think about how your example work
sena_kun this way your Proc::Async jobs will be done in parallel with a fixed batch size
I wrote it with some working code, but if I add non-runnable pseudocode, it'll be like... 17:50
sub do-one { with @queue.shift -> $el { my $proc = Proc::Async.new(...); whenever $proc.out {} do-one } }; do-one for ^$batch-size 17:51
ugh

sena_kun sub do-one { with @queue.shift -> $el { my $proc = Proc::Async.new(...); whenever $proc.out { ...processing... }; whenever $proc.start { ...some post-processing... do-one() } } }; do-one for ^$batch-size 17:51
lucs zef questions: 1. Can I tell it to use a directory different from $HOME/.zef? 2. What config file is --config-path about? ("Load a specific Zef config file") 17:54
xinming I'm thinking, how can perl6 do so much magic. 17:55
I'll check doc about whenever and react
raschipi xinming: Alsdo check .race
xinming sena_kun: So, for whenever block without react is ok?
I thought whenever should be only used in react or supply block. 17:56
sena_kun xinming, no, react is necessary
xinming raschipi: Ok, WIll check, Thanks.
sena_kun: So, for second example, there should be a react block wrap all the code, right? 17:57
17:57 zacts left
sena_kun xinming, ah, well, the second example is incomplete. I just shown how can `do-one` look like to be closer to your(probably) usecase, instead of dumb `sleep rand; say` thing. 17:58
to show that in your case you have to recurse not in the end of the block, but whenever the process ends
xinming sena_kun: For the second one, Where should I wrap the react? 17:59
all code? or only the after the Proc::Async.new(...); react { whenever $proc.out { ... }; whenever $proc.start { ...; do-one() } }; do-one for ^$batch-size
sena_kun xinming, you can just take the first one, then paste definition of do-one from the second one instead of the one from the first one. 18:00
give me a second...
xinming, gist.github.com/Altai-man/ca5412b2...005a895ac1 18:01
xinming Thanks. So, react block should be the top-level. 18:03
sena_kun yes
xinming If I understand right, in perl6, We can have only one react block per program, right?
So, We can't do something like this. if blabla { react { ... } } else { }; 18:04
sena_kun why not?
no
react block is just a thing that takes care of your `whenever` subscriptions
give me a second... 18:05
xinming So, all whenever subscribed things, will be shared globally?
hmm
sena_kun xinming, jnthn.net/papers/2019-gpw-react-sup...enever.pdf <- I recommend reading this
it is an awesome reading and it just explains the thing I remembered out of this paper... :)
xinming Ok, THanks. I don't know that material. 18:06

tony-o_ lucs: you can use somewhere else with the env var XDG_CONFIG_HOME so long as there is a child zef/config.json 18:17
18:17 tobs left, tobs joined
tony-o_ --config-path allows you to use a custom config file, for example, if you want to muck around with some modules or write your own for fetching/updating/testing/whatever you could copy zef's %?RESOURCES<config.json> somewhere, modify it, and then use that config path temporarily 18:19

kawaii Using DBI, when I select a single column from a table and then do `my @stuff = $query.allrows;` I get a nested array each time like `[[hello], [world]], is there some operator I can use to prevent that? 18:46
sena_kun kawaii, just you `$stuff`? 18:50
oops
m: sub foo { [1], [2] }; my $a = foo; say $a
evalable6 ([1] [2])
kawaii well, I want to return a non-nested array 18:51
sena_kun m: sub foo { [1], [2] }; my $a = |foo; say $a
evalable6 ([1] [2])
sena_kun m: sub foo { [1], [2] }; my $a = foo.flat; say $a
evalable6 (1 2)
sena_kun kawaii, like a flatted one or?
kawaii eh I think, i.e. [hello, world, goodnight, world] instead of [[hello], [world], [goodnight], [world]] 18:52
sena_kun kawaii, try `flat`
either a method or a subroutine, as you see fitting... 18:53
kawaii sena_kun: perfect, thank you!

Elronnd is there a good way to get namespaced enums? So far I've been doing module A is export { enum <X Y Z> }, but it would be nice to say something like 'better enum A<X Y Z>' 20:43
(so I can refer to A::X or A.X or something like that, not just bare X)
or, rather, so I'm forced to refer to it with the namespace 20:47

kawaii I have issues with DBIish that are probably easy to fix but complicated to explain 22:19

sena_kun kawaii, one question... 22:43
maybe I don't understand something, but in `get-natures` you have `$_<name> => $_` for every row. 22:44
kawaii, but in your table select I don't see such a column. maybe you want `$_<nature> => $_`?
kawaii hmmmmmmmm!
how did I miss that
maybe because I'm really tired 22:45
sena_kun the error is saying that you are using Any in place of something that can be a Str.
kawaii, no problem, it happens sometimes. Take care and take your time to rest!
