digitalmars.D.learn - directory wildcard

According to:
http://dlang.org/phobos/std_path.html#globMatch

it is possible to use wildcards spanning multiple directories.

assert (globMatch(`foo/foo\bar`, "f*b*r"));

But wildcards with dirEntries() seem less powerful.

`c:\partial*\path\*.d`

If I were to use:
absolutePath + filter! + globMatch

I would expand too many unrelated directories, no?

I happen to know in my case that 'partial*' will match exactly 
one directory, but I don't know the complete name...

So am I left with tokenizing dirSeparator and 'cd' into one 
directory at a time? Or am I missing some magic D function which 
does everything? (wouldn't be the first time that happened to me 
;) hence my question).

I haven't used globMatch, but I've used nested dirEntries 
wildcard expansion loops.

I used SpanMode.shallow parameter with dirEntries to limit 
matches to one directory level.

I don't change directories with cd.  I just create a list of 
matches for the first level partial match, then create an inner 
loop that concatenates the matches from the first partial match 
and calls dirEntries again.


Here is a link to some code for the wildArgv single level search 
that I'm using.

This is roughly how I was using it, related to your example

	string[] argv;
	argv ~= r"c:\partial*";
	foreach( dirn; wildArgvs(argv[0..$])){
		string[] argv2 = null;
		argv2 ~= dirn ~ r"\path\*.d";
		foreach( filen; wildArgvs(argv2[0..$])){
                    do something with filen
                 }
         }

Thanks for your help :)
