Script 2 Script is a programming language translator.
It aim to translate any high level language into any language. (named ori -> goal)

The first POC is to translate Python -> Javascript (in a way similar to Pyjamas)

The basic idea is to translate the ori into a simplier language first.
(Like the GCC compiler which have a GIMPLE ast tree)
It goes like this ori -> SIMPLE -> goal

Status :
 - SIMPLE is not yet fully defined. It lacks a lot about libraries
 - The syntax of Python is well advanced into SIMPLE.


What simple sould have :
 - function and class
 - variable declaration each time (as an object of more precise)
 - classes are not changeable at runtime (or are they ?)
 - It have no hyheritance, all should be done by hand
 - No private or protected function/variable
 - method and function are the same, method should return null
 - Exception (try/a single catch/finally)
 - if/while/class/fct are expression (everything return something)
 - Content is simplified (if had always an else, while/for/foreach => do while)
 - Class functions are not attached to the current object
 - lambda functions
 - new Object() is a special expression (not like python)


The way it will work, all the ori code should be loaded once, then translated.
The optimisation part can't be done if only part of the language is loaded at a time.





Python => AST => SIMPLE => AST => Javascript


Python stuff that need adaptation :
 - Yield
 - Long data type
 - Function
 - Import
 - Getter/setters
 - __call__
 - operators
 - dir
 - getattr/setattr

Make a configuration
[input]
  ast2simple
  astParsing
  source2ast
[optimisation]
  simpleParsing
  optimisation
[output]
  simple2ast
  astParsing
  ast2source

Make a library by module, so it can be adapted for each languages

Code :
 - Init, Commun
 - Library
 - Source by module
   - Modules = [expressions]
     - expression have the source line information
