First of all it's seems bug in docs:
void main(string[] args)
{
getopt(
args,
"length", &length, // numeric
"file", &data, // string
"verbose", &verbose, // flag
"color", &color); // enum
...
}
with args inside getopt I am getting:
C:\D\dmd2\windows\bin\..\..\src\phobos\std\getopt.d(547):
Deprecation: using * o
n an array is deprecated; use *(receiver).ptr instead
C:\D\dmd2\windows\bin\..\..\src\phobos\std\getopt.d(547): Error:

http://dlang.org/phobos/std_getopt.html
But problem that I do not know how handle not existing values:
void main(string[] args)
{
args.getopt
(
"help", &help
);
}
app.exe -sss
causes crash:
std.getopt.GetOptException at C:\D\dmd2\windows\bin\..\..\src\phobos\std\getopt.d(4
63): Unrecognized option -sss
----------------
