# Use ag instead of the default find command for listing path candidates.
# - The first argument to the function is the base path to start traversal
# - Note that ag only lists files not directories
# - See the source code (completion.{bash,zsh}) for the details.
# - ag only lists files, so we use with-dir script to augment the output

`only-dir` and `with-dir` scripts can be found [here][dir-scripts]. They are
written in Ruby, but you should be able to rewrite them in any language you
prefer.
