Glob object model support for **

[kunalkaroth]

Your globbing library is pretty nice. I was wondering if there’s a way to glob a pattern like this using the GlobBuilder: [a-zA-Z0-9]**

I can do it with string parsing, Glob.Parse(); but I seek high performance and was wondering if it would be possible to use the GlobBuilder to achieve the same.
new GlobBuilder().LetterInRange('a', 'z').Wildcard().WildCard() -> [a-z]**

.Wildcard().WildCard() doesn't seem to be equivalent to "**".

Also, another thing that’s problematic is being able to do, [a-zA-Z0-9]**.

Finally, I want to glob files with a certain extension for e.g., *.pdb this doesn't seem to work at the moment?

Thanks!
For .Wildcard().WildCard() I think you want .DirectoryWildcard()

For [a-zA-Z0-9]** are you saying you want to match one single character that is within the range a-z or A-Z or 0-9, followed by anything?

** can only be used when its the only thing in a segment.. i.e foo/**/bar is fine. foo** is not fine.

At the moment I think you could create three seperate globs like so:

[a-z]/**, [A-Z]/** and [0-9]/**

Using the glob builder that might be something like:

var lowerCase = new GlobBuilder().LetterInRange('a', 'z')
                                                     .PathSeperator(PathSeperatorKind.BackwardSlash)
                                                     .DirectoryWildcard()
                                                     .ToGlob();

var upperCase = new GlobBuilder().LetterInRange('A', 'Z')
                                                     .PathSeperator(PathSeperatorKind.BackwardSlash)
                                                     .DirectoryWildcard()
                                                     .ToGlob();

var number = new GlobBuilder().NumberInRange(0,9)
                                                     .PathSeperator(PathSeperatorKind.BackwardSlash)
                                                     .DirectoryWildcard()
                                                     .ToGlob();

Actually you can condense that to two seperate globs, by doing a case-insenstive match for the a-z. For example:

var options = new GlobOptions();
options.Evaluation.CaseInsensitive = true;

var letterGlob = new GlobBuilder().LetterInRange('a', 'z')
                                                .PathSeperator(PathSeperatorKind.BackwardSlash)
                                                .DirectoryWildcard()
                                                .ToGlob(options);

var numberGlob = new GlobBuilder().NumberInRange(0,9)
                                                     .PathSeperator(PathSeperatorKind.BackwardSlash)
                                                     .DirectoryWildcard();

var result = letterGlob.IsMatch("a/foo/bar/baz") || numberGlob.IsMatch("a/foo/bar/baz");

However I am not sure I can do better than this seperate glob idea at present - i.e I don't think you can create a single glob, that matchesa single character that is within the range a-zA-Z0-9 at present.

Hopefully that makes sense to you.

To glob files with a certain extension?

*.pdb should work for example.

if you want any directory: /**/*.pdb

You can have a look at the test cases as they might help aid you.

Closing this for now, hopefully your question is answered but let me know if not.

@dazinator : Thanks for the detailed responses. I wasn't aware of the .DirectoryWildcard() for some reason. :)
