<article> <h2>APL mode</h2> <form><textarea id=“code” name=“code”> ⍝ Conway's game of life

⍝ This example was inspired by the impressive demo at ⍝ 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 gen ← {' #'[(life ⍣ ⍵) board]}

⍝ Show first three generations (gen 1) (gen 2) (gen 3) </textarea></form>

  <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>
