⍝ This example was inspired by the impressive demo at

⍝ http://www.youtube.com/watch?v=a9xAKttWgP4

⍝ Create a matrix:

⍝ 0 1 1
|
|
|
⍝ 1 1 0
|
|
|
⍝ 0 1 0
|
|

creature ← (3 3 ⍴ ⍳ 9) ∈ 1 2 3 4 7 ⍝ Original creature from demo
|
|
|
creature ← (3 3 ⍴ ⍳ 9) ∈ 1 3 6 7 8 ⍝ Glider
|
|
|
|
|
|
⍝ Place the creature on a larger board, near the centre
|
|
|
board ← ¯1 ⊖ ¯2 ⌽ 5 7 ↑ creature
|
|
|
|
|
|
⍝ A function to move from one generation to the next
|
|
|
life ← {∨/ 1 ⍵ ∧ 3 4 = ⊂+/ +⌿ 1 0 ¯1 ∘.⊖ 1 0 ¯1 ⌽¨ ⊂⍵}
|
|
|

⍝ Compute n-th generation and format it as a
|
|

⍝ character matrix

<p>Simple mode that tries to handle APL as well as it can.</p>
|
|
|
<p>It attempts to label functions/operators based upon
|
|
|
monadic/dyadic usage (but this is far from fully fleshed out).
|
|
|
This means there are meaningful classnames so hover states can
|
|
|
have popups etc.</p>
