Glob but not fnmatch?

Can't imagine this is right (Linux, Ruby 1.8.4)

  Dir.glob('lib/**/*') #=> [ 'lib/facets.rb' ]

  File.fnmatch?('lib/**/*', 'lib/facets.rb') #=> false

In the mean time, anyone got a working Ruby-coded #fnmatch? I can use?

Hi!

It does seem strange...

JRuby does it like this in Java, it should be exceedingly trivial to
convert to Ruby:

        checkArgumentCount(args, 2, -1);
        String pattern = args[0].convertToString().toString();
        RubyString path = args[1].convertToString();
        int opts = (int) (args.length > 2 ?
args[2].convertToInteger().getLongValue() : 0);

        boolean dot = pattern.startsWith(".");
        
        pattern = pattern.replaceAll("(\\.)", "\\\\$1");
        pattern = pattern.replaceAll("(?<=[^\\\\])\\*", ".*");
        pattern = pattern.replaceAll("^\\*", ".*");
        pattern = pattern.replaceAll("(?<=[^\\\\])\\?", ".");
        pattern = pattern.replaceAll("^\\?", ".");
        if ((opts & FNM_NOESCAPE) != FNM_NOESCAPE) {
            pattern = pattern.replaceAll("\\\\([^\\\\*\\\\?])", "$1");
        }
        pattern = pattern.replaceAll("\\{", "\\\\{");
        pattern = pattern.replaceAll("\\}", "\\\\}");
        pattern = "^" + pattern + "$";
        
        if (path.toString().startsWith(".") && !dot) {
            return getRuntime().newBoolean(false);
        }

        return getRuntime().newBoolean(Pattern.matches(pattern,
path.toString()));

As far as I can see File.fnmatch does not support directory path
matching with "**":
http://www.ruby-doc.org/core/classes/File.html#M000012

So although this may seem inconvenient / asymmetric behavior conforms
at least to the docs.
