Class Method Details

.merge(*filesets) ⇒ Object

Produce a hash of files, with merged so that earlier files with the same postfix win. E.g., /dir1/subfile beats /dir2/subfile. It’s a hash because we need to know the relative path of each file, and the base directory.

This will probably only ever be used for searching for plugins.

  result

Instance Method Details

#files ⇒ Object

Return a list of all files in our fileset. This is different from the normal definition of find in that we support specific levels of recursion, which means we need to know when we’re going another level deep, which Find doesn’t do.

  # any slashes that might end up at the beginning of the path.

  # And add the path itself.
