XGetopt provides drop-in Unix-style command line processing for Win32 and MFC applications

Introduction

I have ported many apps (probably too many!) from Unix to Windows, and most of them need some command line processing. In Unix, standard method is to call getopt(), but there is no equivalent in Windows. I have gotten so used to getopt() that I like to use it even in new Windows apps - it has a clean interface that is very understandable and self-documenting.

XGetopt Demo

So here is my version of getopt() for Windows. Please note it does not have all features of latest GNU getopt() - the limitation are documented in source header. It is pretty much a drop-in replacement for any app already using getopt().

The demo project provides a sample app that shows how command line is processed. Press "Call getopt" button and getopt() will be invoked with command line you have entered.

How To Use

To integrate XGetopt into your own app, you first need to add following files to your project:

  • XGetopt.cpp
  • XGetopt.h

Next, include header file XGetopt.h in dialog's .cpp file (if it is a dialog-based app) or your CWinApp .cpp, and create a ProcessCommandLine() function, like the one in the demo app. See XGetoptTestDlg.cpp for an example.
