Hahahaha
I didn't mean to ask for tech support for this particular issue because it looks like it was already well documented in the wiki and such, but thanks thanks a lot for your time and kindness :)

@dzaima @dzaima Awesome! I tried setxkbmap -layout pt,apl -variant ,dyalog -option 'grp:caps_switch' and for now I'm happy with it!

But then I'm unable to type @ € { [ ] } the usual way

In my case, with PT layout enabled I can use AltGr+Shift+J and Shift+AltGR+J to type ⍤
diogotito
Jan 27, 2021 12:57
@dzaima You're right!
diogotito
Jan 27, 2021 12:55
@dzaima thanks for pointing me that

setxkbmap -layout gb,apl -variant ,dyalog -option 'grp:switch' allows my to type ⍤ with Shift+J when the "apl" layout is enabled.

@Adám It's the first thing in the wiki page. I hadn't read it until now :'D
diogotito
Jan 27, 2021 12:39
@dzaima That works like a charm! I'll incorporate that in my configuration
diogotito
Jan 27, 2021 12:33
Right now I have
{ 2160 1620÷⍵ }¨ ⍳5
diogotito
Jan 27, 2021 12:33
Oh, APL distinguishes between the two?
diogotito
Jan 27, 2021 12:32
@Adám So, as I as saying,
I have a tablet with dimensions `2160 1620`
I want to write a nice APL expression to have
2160 1620 ÷ 1
2160 1620 ÷ 2
2160 1620 ÷ 3
and so forth

I used Super+Return to spawn a terminal but that sent Enter to the chat
diogotito
Jan 27, 2021 12:29
It doesn't, sorry for the confusion
diogotito
Jan 27, 2021 12:25
Oh, didn't notice that troubleshooting guide, thanks :D
diogotito
Jan 27, 2021 12:24
No problem, I have a rather unusual setup and I'm still fiddling with stuff xD
diogotito
Jan 27, 2021 12:23
oops, sorry, the apl Xorg key layout hijacked my Shift+Return XD

Jan 27, 2021 12:23
BTW I tought up a tiny problem that I'm wondering how to do in APL:
I have a tablet with

Ok, thanks for the correction

⋄⍳⌊0.5*⍨7
diogotito
Jan 27, 2021 12:16
@Adám Thanks for the clarification. Do APLers also call user-defined functions functions?
diogotito
Jan 27, 2021 12:03
Thanks @MartinJaniczek, I'll try out the modulo operator now!
diogotito
Jan 27, 2021 11:45
Hello! I've been thinking about expressing an `IsPrime` function with simple operations for a while.
I managed to cut it down to
`⋄{2=+/⍵(÷=(⌊÷))⍳⍵}¨⍳30`
diogotito
Jan 19, 2021 01:21
Oh, so ⌊ and ⌈ live a double life as floor/ min and ceiling/max

Oh I see. Thanks!

@Adám Exactly! I'm still getting overwhelmed by the notation
diogotito

Pretty cool!
diogotito
Jan 19, 2021 00:56
@rak1507 Oooh! I get it now! +/÷≢is Sum divided by Length!
diogotito
Jan 19, 2021 00:51
oh, they can be either unary or binary
diogotito
Jan 19, 2021 00:50
In your example, f and h are unary functions and g is binary, right?
diogotito
Jan 19, 2021 00:47
Let that sink into my head xD
diogotito
Jan 19, 2021 00:45
f <*> g reuses the operand I guess
diogotito
Jan 19, 2021 00:44
It was funny
diogotito
Jan 19, 2021 00:44
oh

Jan 19, 2021 00:44
ap, If I recall correctly

Yes, I read some chapters from Learn You a Haskell

Quite!
