Hi,
Is it by design that single-letter option needs to be glued to its
argument, like "-ofilename", or is it a bug in implementation?
Source:
import std.stdio;
import std.getopt;
void main(string[] args)
{
string outputFile;
getopt(args,
config.passThrough,
"o|output-filename", &outputFile);
writeln(args);
writeln("'" ~ outputFile ~ "'");
}
Results:
>test.exe -o somename
test.exe somename
''
>test.exe -osomename
test.exe
'somename'

It's by design in order to avoid confusion with parameterless options.
Your example works with either of these invocations:
./prog -ofilename
./prog -o=filename
./prog --o=filename
but not others.

Thanks very much.
I suggest adding this info to official docs (it's not obvious, and a bit
confusing, since long options work with whitespace(s)).
