Ngn/apl: Difference between revisions

Revision as of 12:45, 27 December 2020

ngn/apl is an APL bytecode compiler and interpreter by Nick Nickolov. Because it is implemented in Javascript, it can be run in Node.js or any modern browser.

ngn/apl supports most of the core language of Dyalog APL 14.0,: dfns ({⍺ ⍵}), nested arrays, complex numbers (1j2), forks and atops, strand assignment ((a b)←c), indexed assignment (a[b]←c), and user-defined operators ({⍺⍺ ⍵⍵}), but does not support Key (⌸), Rank (operator (⍤) tradfns (∇R←X f Y), non-zero index origin (⎕IO←1), comparison tolerance (⎕CT), prototypes (it always uses zero as fill), modified assignment (x+←1), keywords (:If), object-oriented programming, or namespaces. It extends Dyalog APL with infinities (¯ or ∞) and a few additoinal primitives.
