Feature #7360


Adding Pathname#glob

Added by aef (Alexander E. Fischer) over 10 years ago. Updated over 5 years ago.

Target version:


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 ='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.

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)
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.
