A simple tree structure for working with FilePath objects in ruby. I simply took the simple_tree module from https://github.com/ealdent/simple-tree and hacked it into Pathname (http://www.ruby-doc.org/stdlib-2.0/libdoc/pathname/rdoc/Pathname.html) from the std-lib. This means you get all the awesome features of working with Pathname, as well as making it easy to examine a filepath's ancestors and descendants.

FileTree

A simple tree structure for working with FilePath objects in ruby. I simply took the simple_tree module from https://github.com/ealdent/simple-tree and hacked it into Pathname from the std-lib. This means you get all the awesome features of working with Pathname, as well as making it easy to examine a filepath's ancestors and descendants.

Usage

Install

install with: gem install filetree

Examples

    require "filetree"

    tree = FileTree.new('/home/user/test/test1/test2')
    # => #<FileTree:/home/user/test/test1/test2>

    tree.parent
    # => #<FileTree:/home/user/test/test1>

    tree.ancestors
    # => [#<FileTree:/home/user/test>,
    #     #<FileTree:/home/user>,
    #     #<FileTree:/home>,
    #     #<FileTree:/>]

    tree.descendants
    # => [#<FileTree:/home/user/test/test1/test2/testee>,
    #     #<FileTree:/home/user/test/test1/test2/testee/testeggg>,
    #     #<FileTree:/home/user/test/test1/test2/testee/testeggg/test4>,
    #     #<FileTree:/home/user/test/test1/test2/testee/testeggg/test4/myfile.txt>,
    #     #<FileTree:/home/user/test/test1/test2/testee/testeggg/test3>,
    #     #<FileTree:/home/user/test/test1/test2/testee/testeggg/test3/no>,
    #     #<FileTree:/home/user/test/test1/test2/testee/test4>,
    #     #<FileTree:/home/user/test/test1/test2/testee/test4/myfile.txt>,
    #     #<FileTree:/home/user/test/test1/test2/testee/test3>,
    #     #<FileTree:/home/user/test/test1/test2/testee/test3/no>]

    des_arr = tree.descendants.map { |e| FileTree.new(e.relative_path_from(FileTree.new('/home/user'))) }
    # => [#<FileTree:test/test1/test2/testee>,
    #     #<FileTree:test/test1/test2/testee/testeggg>,
    #     #<FileTree:test/test1/test2/testee/testeggg/test4>,
    #     #<FileTree:test/test1/test2/testee/testeggg/test4/myfile.txt>,
    #     #<FileTree:test/test1/test2/testee/testeggg/test3>,
    #     #<FileTree:test/test1/test2/testee/testeggg/test3/no>,
    #     #<FileTree:test/test1/test2/testee/test4>,
    #     #<FileTree:test/test1/test2/testee/test4/myfile.txt>,
    #     #<FileTree:test/test1/test2/testee/test3>,
    #     #<FileTree:test/test1/test2/testee/test3/no>]

    des_arr.first
    # => #<FileTree:test/test1/test2/testee>

    des_arr.last.ancestors # infinite loop. "ancestors" depends on hitting "/" to stop.

    # the "tree_rep" method provides prettyprinting for creating your own to_s methods
    puts tree.tree_rep
    # => nil
