I implemented tree commnad with go.
We use yaml for tree definition.

Installation and usage

$ make setup

About Tree Yaml

For the definition of tree, from the go-tree onwards, define a tree structure with yaml's array. For directories, add a semicolon at the end. You can define the root directory name with root-dir(default: ".").

root-dir: "Sample"
go-tree:
  - fizz
  - buzz
  - dir1:
    - comp1-1
    - comp1-2
    - comp1-3
    - comp1-4
  - dir2:
    - comp2-1
    - comp2-2
    - comp2-3
    - comp2-4
    - dir3:
      - comp3-1
      - comp3-2
      - dir4:
        - comp4-1
        - comp4-2
        - comp4-3
      - comp3-3
      - comp3-4
    - comp2-5
    - comp2-6
  - dir5:
    - comp4-1
    - comp4-2
    - comp4-3
    - comp4-4
  - foo
  - bar
