Support for glob with parent directory included in single string

[xmichaelx]

It would be useful if methods Glob.Files and Glob.Directories would support providing only one glob with parent directory concatenated like: C:/**/*.cs. This is something that is available in Python glob module.

Would it be possible to add such functionality or would you accept PR with such functionality?

I just tested what you are describing in the UI and it appears to work. Maybe I am not following your specific use case? Can you provide a code sample that fails?

These are the parameters I used in the Glob tester UI:

I mean the ability to call:

var files = Glob.Files("C:/**/*.cs");

instead of having to providing working directory separately:

var files = Glob.Files("C:/", "**/*.cs");

Is the former somehow possible?

[kthompson]

Oh yes I see now. I would probably try to parse the beginning of the pattern until a non-literal was found which would allow us to split the pattern into the constant part ie "c:/" and the pattern "**/*.cs" then use the existing overload to return the results.
