arith2js – Calculator Transpiler with Scope Analysis

A transpiler that converts calculator expressions (supporting complex numbers, min/max operators, variables, and print statements) into executable JavaScript code. Built on jison and extended from a basic arithmetic calculator, version 1.0.0 adds scope analysis to enforce variable declaration before use, reference semantics for complex objects, and comma-separated expression sequences. Key differentiators: full complex arithmetic transpilation, meticulous error reporting with line/column, and avoidance of primitive method calls via explicit Complex() wrapping.
