otherfunc-apl

APL subset interpreter with Unicode glyphs, ASCII aliases, and SIMD-friendly array storage.

Implementation

• All numeric values are f64; arrays stored as contiguous Vec<f64> for autovectorization
• Right-to-left evaluation with strand notation (adjacent values form vectors)
• 17 scalar functions (element-wise with scalar extension), 7 structural functions, 4 operators
• Operators: reduce (/), scan (\), each (¨), outer product (∘.f)
• Unicode APL glyphs and ASCII aliases: iota for ⍳, rho for ⍴, rev for ⌽, mul for ×, div for ÷, etc.
• Default instruction limit: 10,000,000 (configurable via with_instruction_limit())

Install

cargo install --path .

Usage

# Inline code
apl "2+3"
apl "+/⍳100"
apl "∘.×⍳5"

# ASCII aliases
apl "+/iota 100"

# From file
apl -f program.apl

As a Library

use otherfunc_apl::AplInterpreter;
use otherfunc_core::Interpreter;

let mut apl = AplInterpreter::new();
let output = apl.execute("+/⍳100", "").unwrap();
assert_eq!(output, "5050");
