spacetree

A Ruby library to generate a tree structure from a text file indented by spaces.

Example

Given a text file tree.txt

foo
  bar
  baz

Parsing it:

require 'spacetree'
parser = Spacetree::Parser.new
tree = parser.parse File.read('tree.txt')
# tree is root node
tree.value # => nil
tree.children.map(&:value) # => ["foo"]
tree.children.map(&:children).flatten.map(&:value) # => ["bar", "baz"]

Emitting a tree as indented text:

puts tree.emit

or simple

puts tree
