MoonScript

MoonScript was inspired by CoffeeScript and is one of the fastest to-Lua compilers around.

MoonScript code can be compiled at runtime or at a peculiar time and have the code executed later.

What is new in this release:

• Added continue keyword for skipping the current iteration in a loop.
• Added string interpolation.
• Added do expression and block.
• Added unless as a block and line decorator. Is the inverse of if.
• Assignment can be used in an if statement's expression.
• Added or= and and= operators.
• @@ can be prefixed in front of a name to access that name within self.__class
• @ and @@ can be used as values to reference self and self.__class.
• In class declarations it's possible to assign to the class object instead of the instance metatable by prefixing the key with @.
• Class methods can access locals defined within the body of the class declaration.
• Super classes are notified when they are extended from with an __inherited callback.
• Classes can now implicitly return and be expressions.
• local keyword returns, can be used for forward declaration or shadowing a variable.
• String literals can be used as keys in table literals.
• Call methods on string literals without wrapping in parentheses: "hello"\upper!
• Table comprehensions can return a single value that is unpacked into the key and value.
