Winim - Nim's Windows API and COM Library

[Ward]

Hello, everybody. Happy to introduce my new project - 
[Winim](https://github.com/khchen/winim).

I like Nim, and I usually coding under Windows. There is a oldwinapi for 
Windows API wrapper. But it is old and incompleted. So I start this project. 
Compare to oldwinapi, this module:

  * More complete (of course).
  * Switch between unicode/ansi mode without problem.
  * Easily deal with wide-char string and multibyte string like built-in string 
type.
  * Add Winodws COM support, use Nim to play with COM object like a script 
language.



**Install**
    
    
    nimble install https://github.com/khchen/winim
    

**MessageBox Example**
    
    
    import winim
    MessageBox(0, "Hello, world !", "Nim is Powerful", 0)
    

**Interface Example**
    
    
    import os, winim
    
    var
      pIL: ptr IShellLink
      pPF: ptr IPersistFile
    
    try:
      CoInitialize(nil)
      
      if CoCreateInstance(&CLSID_ShellLink, nil, CLSCTX_LOCAL_SERVER, 
&IID_IShellLink, cast[ptr PVOID](&pIL)).FAILED: raise
      defer: pIL.Release()
      
      if pIL.QueryInterface(&IID_IPersistFile, cast[ptr PVOID](&pPF)).FAILED: 
raise
      defer: pPF.Release()
      
      if pIL.SetPath(getAppFilename()).FAILED or pPF.Save("link.lnk", 
true).FAILED: raise
    
    except:
      echo "something wrong !!"
    

**COM Example**
    
    
    import winim.com
    
    comScript:
      var dict = CreateObject("Scripting.Dictionary")
      dict.add("a", "the")
      dict.add("b", "quick")
      dict.add("c", "fox")
      dict.item("c") = "dog" # this line needs comScript macro
      
      for key in dict:
        echo key, " => ", dict.item(key)
