How to use FileSystemGlobbing.Matcher

Question

How to use the Microsoft.Extensions.FileSystemGlobbing.Matcher class. I read the documentation, but I still don't understand it.

I expect to be able to exclude the specified folder(use glob), but the code does not work:

var matcher = new Matcher();
matcher.AddExclude("foo/*.txt");
matcher.Match(new[] { "foo/a.txt", "foo/b.md", "bar/a.txt" }); // HasMatches: false

Expected:

foo/b.md
bar/a.txt

Actual:

// nothing

You have to specify what to include:

var matcher = new Matcher();
matcher.AddInclude("**"); // <-- this line is added
matcher.AddExclude("foo/*.txt");
matcher.Match(new[] { "foo/a.txt", "foo/b.md", "bar/a.txt" });
