Homecoming

Homecoming let's you easily traverse all parent directories of a given or the current directory.

This comes in handy when searching for a config file with settings that can be overridden by the same config file in a lower level directory (a popular example being .gitignore).

Installation

Add this line to your application's Gemfile:

gem 'homecoming'

And then execute:

$ bundle

Or install it yourself as:

$ gem install homecoming

Usage

Finding files

Homecoming.find searches for a given filename in the current and all parent directories.

# Given the following directory structure:

/
  home/
    rrrene/
      projects/
        your_project/
          .yourconfig
      .yourconfig

Homecoming.find(".yourconfig", "/home/rrrene/projects/your_project")
# => ["/home/rrrene/.yourconfig",
      "/home/rrrene/projects/your_project/.yourconfig"]

If no path is given as second parameter, the current directory is the starting point of the traversal.

Traversing parents

Homecoming.each traverses and yields the given and all parent directories.

Homecoming.each("/home/rrrene/projects/your_project") do |dir|
  # ...
end

If no path is given, the current directory is the starting point of the traversal.

In our example, this would yield the following directories beginning with the given/current one:

"/home/rrrene/projects/your_project"
"/home/rrrene/projects"
"/home/rrrene"
"/home"
"/"
