Haxe to nim transpiler

Warning. Just an experiment. Lot of bugs!!!

Transpiler from haxe to nim (http://nim-lang.org/)

The main goal for now is:

• High performance.
• Low memory footprint.
• Stable garbage collector, or maybe no GC at all (owned/unowned ref).
• Async IO: Files, TCP, UDP, HTTP, HTTPS, Websockets.

What it's all good for?

Backend, micro services, iot, calculations, haxe compiler :)

Why not go, rust, D and other languages?

Because.

What it can do:

• Classes:
  • inheritance
  • constructors
  • super call
  • static and instance methods
  • instance fields
• Interfaces
• Typedefs
• Anonymous
• Basic types:
  • Int
  • Float
  • String
  • Bool
  • Generic Array
  • IntMap, StringMap, ObjectMap
• Enums and ADT
• Abstracts and enum abstracts
• Generics
• GADTs
• Expressions:
  • for
  • while
  • if
  • switch
• Closures
• Externs
• Basic file reading by File.getContent
• haxe.Json
• Stdin output by trace

How to use it

• Install lix packet manager https://github.com/lix-pm/lix.client
• Install nim compiler with https://github.com/dom96/choosenim
• Install craxecore library by "nimble install https://github.com/RapidFingers/Craxe?subdir=core"
• Create lix project
• Select haxe 4.0.0-rc3 compiler
• Add craxe library with lix from github https://github.com/RapidFingers/Craxe
• Add build.hxml with following strings:
  -cp src
  --macro craxe.Generator.generate()
  --no-output
  -lib craxe
  -main Main
  -D nim
  -D nim-out=main.nim
• Add some simple code to Main.hx
• Launch "haxe build.hxml"
  It will generate code and will launch the nim compiler
  "nim c -d:release filename.nim"
