Introduction

It takes advantage of C# features such as collection initializers and lambda delegates to provide a short, concise specification of the option names to parse, whether or not those options support values, and what to do when the option is encountered. It's entirely callback based:

History

Usage

var verbose = 0;
var show_help = false;
var names = new List<string> ();

var p = new OptionSet () {
  { "v|verbose", v => { if (v != null) ++verbose; } },
  { "h|?|help",  v => { show_help = v != null; } },
  { "n|name=",   v => { names.Add (v); } },
};

int          verbose   = 0;
bool         show_help = false;
List<string> names     = new List<string> ();

OptionSet p = new OptionSet ()
  .Add ("v|verbose", delegate (string v) { if (v != null) ++verbose; })
  .Add ("h|?|help",  delegate (string v) { show_help = v != null; })
  .Add ("n|name=",   delegate (string v) { names.Add (v); });
