ObjJAcornCompiler - JavaScript/Objective-J Transpiler

ObjJAcornCompiler is a tiny, fast JavaScript and Objective-J transpiler with a built-in C-like preprocessor, written in JavaScript. The current version is 1.0.0-10 (pre-release), built on an extended Acorn parser. It supports multiple ECMAScript versions (ECMA5, ECMA8, latest), loose mode, and various output options like AST generation and source maps. Key differentiators: it is the primary transpiler for the Cappuccino framework, targeting Objective-J 2.0 syntax; includes a preprocessor for macros and conditionals; and is available as an npm package. However, it cannot compile Objective-J code that depends on other files without the Objective-J runtime.
