====== Emulating of WSH ======

To make it easy migrate already existing scripts written for [[http://msdn.microsoft.com/en-us/library/9bbdkx3k(v=vs.84)|WSH]] to HippoEDIT scripts, or just simplify your learning curve with HippoEDIT scripting, HippoEDIT provides limited emulation of WSH objects and methods.\\ 
Explicitly there are following objects:
  * **WScript** (IWScript),
  * **TextStream** (IWshTextStream) and
  * **Arguments** (IWshArguments)
  * rest of objects can be created with help of //WScript.CreateObject//

Following methods are not supported:
  * [[http://msdn.microsoft.com/en-us/library/ccxe1xe6(v=VS.84).aspx|WScript.ConnectObject]]
  * [[http://msdn.microsoft.com/en-us/library/2d26y0c1(v=vs.84).aspx|WScript.DisconnectObject]]
  * [[http://msdn.microsoft.com/en-us/library/dc1y0x0h(v=vs.84)|WScript.Arguments.ShowUsage]]

Here is simple example that demonstrate emulation:
<file javascript wscript.js>
var WshShell = WScript.CreateObject("WScript.Shell");
var WshExec = WshShell.Exec("cmd /c dir c:\\"); 

while (!WshExec.StdOut.AtEndOfStream) 
        WScript.Echo( WshExec.StdOut.ReadLine() );	

WScript.Echo(WScript.Fullname + ", v:" + WScript.BuildVersion);
WScript.Echo("Hi one");
WScript.Quit(); 
WScript.Echo("Hi two"); // this should not be executed
</file>

After execution inside of HippoEDIT (//Tools->Execute->wscript.js//) you will get following text in [[plugins:output-window|Output Window]]:

<note>If you want to use WSH emulation for [[scripting:python|Python scripts]], be aware that you need to start all your WScript object calls by //Application//. Something like this: //Application.WScript.Echo("...")//.</note>
