Golox

This repo is a go implementation of Lox language. Lox is a dynamic scripting language designed by Bob Nystrom in his book Crafting Interpreter. Lox is really like JavaScript. Refer to chapter 3 of the book for an overview of Lox lang.

This implementation adds some more features:

• Semicolon is not a must. :-)
• Lambda expressions(anonymous functions).
• Support break statement from loops.
• Support getters/setters, static methods for classes.
• Support for ... of statement.
• Support Arrays, Maps.
• Enhanced REPL.

Example

fun fibnacii() {
    var prev = 0, cur = 0

    // lambda expression.
    return () -> {
        if (cur == 0) {
            cur = 1
            return 0
        }

        var res = cur
        cur += prev
        prev = res

        return res
    }
}

var next = fibnacii()
for (var i = 0; i < 10; i += 1) {
    print next()
}
