Ngn/apl

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 , forks and atops, strand assignment , indexed assignment , and user-defined operators , but does not support Key , Rank (operator tradfns , non-zero index origin , comparison tolerance , prototypes (it always uses zero as fill), modified assignment , keywords , object-oriented programming, or namespaces. It extends Dyalog APL with infinities (  or  ) and a few additoinal primitives.

On December 27, 2020, Nickolov announced that he would discard his implementation. Soon after, Adám Brudzewsky took up the mantle of hosting the source and online demo.
