digitalmars.D.learn - getopt short-options documentation

Hi!

Reading through the `getopt` documentation at one point it says:

   "Forms such as -t 5 and -timeout=5 will be not accepted."

But I'm able to to use short options like '-t 5' (with spaces 
between the 't' and the '5'). It seems that this limitation has 
been eliminated and it just-works-now, is it so?

Thx!

Hi Daniel!

Try this one :
-------
module tools.trainer;

import std.stdio, std.getopt;

//////////////////
// Main Program //
//////////////////---------------------------------------------------------
int main(string[] args) {

   dchar    letter = 'ñ';
   string[] inputFiles;
   string[] cmpFiles;


   arraySep = ",";  // defaults to "", separation by whitespace
   auto helpInformation = getopt(args,
                                 "letter|l", "The char that 
represent the input images.", &letter,
                                 "inputf|i", "The files that 
represent the image of the same char.", &inputFiles,
                                 "cmpf|c",   "The files that 
represent images of other chars to compare with.", &cmpFiles);

   if (helpInformation.helpWanted) {
     defaultGetoptPrinter("Some information about the program.",
                          helpInformation.options);
   }

   writeln("Letter selected is: ", letter);
   return 0;
}
---------

trainer -l Y
trainer -lY

Both of them work for me.
