#JLox ##TheOneAndOnly

A minimal language based on the project at craftinginterpreters.com.

This is very similar to the original, although I made a few changes after writing the initial code. Specifically, I:

• Added Anonymous Functions

In the form (fun (){}) they represent LoxFunctions without binding it to a variable. Example:

fun named_func(arg1, callable) {
  print arg1;
  print callable();
}

named_func("Hello", fun() {
  return " World!";
});

This will print "Hello World!".

As a semantic choice, I allowed the expression statement fun (){}; as well as fun (){}();.

• Added Class Methods

By prefixing a method name with class it makes the method a class method, meaning it is owned by the class, but not any instances.

class MyClass {
  class method() {
      print "Class Method!";
  }
}
MyClass.method();

Note that it is a resolver error to use this in a class method.

• Refactored functions.

After doing these two things, I was pulling my hair out with the complex nature of handling both an expression form of functions, and a statement form, so I formally conjoined the two and go rid of the statement form. Semantically, it makes absolutely no difference at all that fun identifier() {} is syntax sugar for var identifier = fun (){} but in the code base it makes for simpler code, so I know to only expect an expression when dealing with functions.
