Reference of Moon Programming Language

This document is a reference to all things about the language.

Why Moon?

Moon is a flexible, easy to learn programming language.

Syntax

Paradigm

Multi paradigm: Object-oriented, Imperative, Functional, Procedural

Keywords

• def: Declare/define variables/functions in the current scope
• global: Declare/define variables and functions in the global scope
• local: Declare/define variables that can only be used on the current scope

Variables

You can declare a variable with var keyword or just declare it with a value (it will declare in current scope)

var foo
var bar = 0
foobar = 2

You can use global to refer a declaration to the global scope.

global foo = 12

Also use local for variables that you will only use in your current scope

local foo = 5
{
  foo = 2
}
print foo // 5

Scope

You can create a scope using { and }

local foo = 5
{
  foo = 2
}
print foo // 5

Also you can use a tab based scope with :. But only compatible with functions and for, while keywords.

while true:
  foo()
  bar()
foobar()

If it have an instruction in the same line of : or theres no additional space/tab added compared to the previous line when using this type of scope you are only able to use one (the next) instruction

while true: foo()
bar() // Not in loop
while true:
bar()
foobar() // Not in loop
