TreeWalker

TreeWalker is an Elixir library to recursively walk through directories, streaming the file paths discovered as it goes.

It can optionally skip directories or return File.Stat structs if enabled.

The full documentation is available at https://hexdocs.pm/tree_walker.

Installation

The package can be installed by adding tree_walker to your list of dependencies in mix.exs:

def deps do
  [
    {:tree_walker, "~> 0.1.0"}
  ]
end

To find all the .json files in a repo, skipping the .git directory, you might do something like:

TreeWalker.stream(path, skip_dir: &String.ends_with?(&1, ".git"))
|> Stream.filter(&String.ends_with?(&1, ".json"))
|> Enum.to_list()
