@AviFS Of course, but I'm pretty sure you've seen it already: xpqz.github.io/learnapl

@Adám Maybe as this? 
supply ← {⍺←⊢ ⋄ ⍺(⊣∘⍺⍺⊣⊢)⍵}

⍝     (f supply) Y
⍝ f Y

⍝     X (f supply) Y
⍝ X

⍝     (A supply) Y
⍝ A

⍝     X (A supply) Y
⍝ X
Oh, actually that ⊣∘A case is incorrect, you should understand the idea though
Adám
Adám
@awagga How would you describe this?
awagga
awagga
supply or compute default / supply or compute overridable default
Adám
Adám
I don't follow. Maybe that ⊣∘A talk throws me of.
awagga
awagga
supply ← {⍺←⍺⍺ ⋄ ⍺⊣⍵}
If function apply, if array constant, unless left argument is present, in which case use left argument as constant
Adám
Adám
Can you think of a single usecase?
awagga

Yes (f g h supply)

Adám
I don't get it.

+⌿÷≢ supply
Adám
Adám
??
awagga

(+⌿÷≢ supply) Y ←→ (+⌿Y)÷(≢Y)
X(+⌿÷≢ supply) Y ←→ (+⌿Y)÷X
I used it yesterday, in my definition of insert as well... which is a good example 
      1 2 3 ('QWER' insert) 3 3⍴⎕A
⍝ Q
⍝ ABC
⍝ W
⍝ DEF
⍝ E
⍝ GHI

      1 2 3 (÷ insert) 3 3⍴⍳9
⍝ 1            0.5   0.3333333333
⍝ 1            2     3
⍝ 0.25         0.2   0.1666666667
⍝ 4            5     6
⍝ 0.1428571429 0.125 0.1111111111
⍝ 7            8     9
So, the use case for supply is providing default values or allowing for different semantics depending on the nameclass of an operand

I guess my head just isn't working, because I still don't get it.

Maybe we should talk sometime?
Adám
Adám
Sure.

This makes me think tacit.help should have a feature where you can define functions/operators as part of a header. Easy way to implement f g h too... :)

Anyone here a Linux user who relies a lot on key compositions (e.g. <compose key> <'> <e> gives é? How annoying would it be if either those were overridden so that <compose key> e gives ∊, and/or changing the existing compose sequences to something longer?
OR more importantly, do you think there's a demand for a prefix-style input method similar to what you get on TryAPL? where instead of holding down a "shifting" key to get APL glyphs, you type one key followed by another?
dzaima

@RikedyP compose sequences don't necessarily need to start with the compose key
RikedyP
RikedyP
@dzaima no, but then it sort of becomes choosing what is an appropriate key I think - although I'll have a think maybe that's something the user can configure
dzaima
dzaima
right; it's not hard to change though, just replace the leading <...> of each line
unfortunately, while <grave> <w> : "⍵" for backtick prefix works, <Alt_R> <w> : "⍵" doesn't
RikedyP
RikedyP
hmmmm
you can set right alt to be Multi_key through various means
then you can have that, but then you could just have the shifting layout as normal
dzaima
dzaima
right, but I wanted to see if there'd be a way to have both a regular compose key and an APL compose key

Funny idea: If you made ⊣ a hybrid with the preference of being {⍺←⍺⍺ ⋄ ⍺⊣⍵} usual ⊣ would be represented as ⊣⊣
Super left tack!

@dzaima that's what I want to find out as well, it may be possible

@RikedyP from my experience with my key composition base APL input method, doing anything other than writing APL code gets annoying easily.

@Adám You're not relying on the Array notation wiki page, are you? Think I'm going to move that to Array notation in Dyalog APL and make something less language-specific and more condensed.

@Marshall I was going to do exactly that (both edit pages open in tabs) as evidenced by my navbox edit, but a home move came in the way. Please do go ahead and do the work!
Marshall
Marshall
Okay, will go for it when I get the chance. Hope your(?) move is going well!

It is indeed both mine and going well. The daily bike ride to the (Danish) office is about the same as from the Dyalog house to Bramley, so I'm getting my exercise too.
