Currently there is only a Pathname.glob method, which allows you to find Pathname objects by a pattern including wildcard characters like '*'.
I would like to be able to use this relative to a current Pathname.
some_directory = Pathname.new('some_directory')
Pathname.glob(some_directory + 'a*') # all children starting with "a"
could then simply be:
some_directory.glob('a*') # all children starting with "a"
If you like the idea, please let me know. I will provide a patch then.
Pathname#glob method implemented.

Here is a patch that adds the functionality as outlined by Alexander. It's using "Pathname#join" to build the glob pattern, and then delegating to "Pathname.glob".
As described in the rdoc, it will accept a single string with a glob pattern, or an array of glob patterns.
The main use case is when you want to do something based relative to a current directory that is already available as Pathname, such as Rails.root in a Rails project. With this, you can say e.g.
to find all ruby files in the current project.

It seems the proposed implementation treats the receiver as a glob pattern.
% ruby -rpathname -e ' class Pathname def glob(pattern, flags = 0, &b) Array(pattern).flat_map do |pat| self.class.glob(join(pat), flags, &b) end end end p Pathname("/b*").glob("i*") ' [#<Pathname:/boot/initrd.img-3.16.0-4-amd64>, #<Pathname:/bin/ip>]
I think it is not intentional.

We looked at this issue at today's developer meeting. As Akira already respond, the proposed patch has a problem. In order to reroute that we need to extend Dir.glob. Nobu opened a ticker for that. Once he finished that, we can resume this one.
