How to return a collection of files from a given directory in Elixir?

In Ruby, I can use 

target_files = Dir["/some/dir/path/*.rb"]
#=> ["/some/dir/path/foo.rb", "/some/dir/path/bar.rb", "/some/dir/path/baz.rb"]

which will return an array of all of the matching files in a directory. How can I do something similar in Elixir?

Path.wildcard/1 can handle recursive folders with two stars '**' (it works similar to Dir.glob in Ruby). E.g.

Path.wildcard("../data/??/**/*.yml")

You're looking for Path.wildcard/2:

iex(1)> Path.wildcard("/tmp/some/dir/path/*.rb")
["/tmp/some/dir/path/bar.rb", "/tmp/some/dir/path/baz.rb",
 "/tmp/some/dir/path/foo.rb"]
iex(2)> Path.wildcard("/tmp/**/*b*.rb")
["/tmp/some/dir/path/bar.rb", "/tmp/some/dir/path/baz.rb"]

And if you want to recursively gather files with a regex, there's :filelib.fold_files/5.
