self-compiled .net hybrids
Posted: 08 Jan 2014 09:03
just expanding idea that I saw here: http_://www.dostips.com/forum/viewtopic.php?f=3&t=4762 .
As the .net framework comes with three default compilers jsc.exe - for javascript , csc.exe - for c# and vbc.exe for visual basic .net I've tried to create a hybrid for each of them (with "hello world " examples only).
jscript.net is the best option according to me - does not require a main method or wrapping something in a class and also supports @if directive - http://msdn.microsoft.com/en-us/library ... xa(v=vs.90).aspx (as well as jscript) so the notorious jscript/bat technique can be used for clear output .It's not so powerful language as C# ,but for a script purposes I think it's better (beware that the WScript methods are not accessible here):
c# more code is required compared to the jscript.net and have unavidable "//>nul 2>nul||" print (may be could be remoted with some namespace definition??).Nothing new here:
Visual Basic - uses similar technique as this here http://stackoverflow.com/a/16622325/388389 .But cannot reduce the initial print of " '1>nul 2>&1 || " , because here is not possible to define a method outside of a class/module or whatever is called :

Imports System
Public Module modmain
' Main is the application's entry point.
Sub Main()
' Write text to the console.
Console.WriteLine ("Hello World using Visual Basic!")
End Sub
End Module
