elcaro oooh, Terminal::Print show-and-tell time! Here's a terminal snake game with "fancy" graphics. Snake can be controlled with via WASD, HJKL, or cursor keys. Pause game with P. 02:37

:(**@rest, *%rest) when assignment signatures do different than function signatures 😔 08:06

CIAvash if you want it to act like function signatures, then you should use binding(:=), not assignment 09:04

Nemokosch very cool stuff! 09:41
09:55 Manifest0 joined
elcaro Thanks 09:59
Nemokosch Terminal::Print could also "get a life", again 10:03
what I'm really curious about for low-level terminal handling is this 10:06
sometimes one just has to deal with Windows
for example because of colleagues who only use that... 10:07

Skarsnik MS push to use the Terminal app now that support lot of thing 13:21
Nemokosch yes, it's like, they do have working choices by now, but it's too often not available still 13:46
:(**@rest, *%rest) does anyone knows why my super implementation doesn't work 13:48
should give this output A.a is called B.a is called 13:49
Nahita => $o); can't initialize a private attribute with that 13:52
it's private 13:53
has $!o is built; might help
to initialize
or has $.o as usual 13:54
:(**@rest, *%rest) oh nice now it worked 13:55
Nahita FWIW, callsame will do too 13:57
Nemokosch I think the problems with callsame arise once you had multiple candidates by argumentation 14:16
like, callsame is perfectly happy to redispatch to a less specific candidate on the same class 14:17
:(**@rest, *%rest) super avoids that 14:18

tg57 I just started learning Raku and was wondering if anyone had good suggestions for practice projects 17:40
18:28 tg57 left 18:55 NemokoschKiwi joined, NemokoschKiwi left
Nemokosch I think it very much depends on what you'd like to learn/achieve 19:15
something with text processing? something about making a port of an existing thing? playing around with some algorithm? some TUI fun like elcaro posted yesterday (mini snake game)? 19:19

nHail This code should be printing the tick onto the screen in ncurses every 0.5 seconds, but I'm not seeing any output. What's going on? I tried a similar thing with say and no ncurses, and it did print every half second as expected. perl my $tickSupply = Supply.interval(0.5); $tickSupply.tap(-> $v { mvaddstr(1, 1, $v); nc_refresh; }); 21:12
ab5tract perl? 21:18
I think you want to wrap that in a react { whenever $tickSupply -> $v { #current tap code } } 21:19
Nemokosch You yourself imply that this is a problem related to ncurses. It's probably not a "beginner question", or even a question that most people have a chance to answer
nHail That's to mark the syntax highlighting lang in discord. There's no raku option so I told it to use perl 21:20
Well, now it's at least giving me an error message 21:23
This type cannot unbox to a native string: P6opaque, Int
thrown on the mvaddstr line 21:24
Nahita $v is integer? 21:25
oh it's a parameter there
i don't know supplies so i shouldn't clutter here
but mvaddstr seems to expect string as its last parameter there 21:26
nHail Okay, I figured it out 21:28
I had a react block earlier in the program which killed the program when I pressed q 21:29
From the docs: > a react block runs where it appears in the code flow
Nemokosch yes; unlike a supply block 21:30
ab5tract yeah, there's that. glad you got it sorted 21:45
