tree_print
A gem for visualizing binary tree data structures in ruby.
Works for any node-based implementations where the node responds to the following methods
node.left # returns node object 'on the left'
node.right # returns node object 'on the right'
node.val # returns value at that node
node.height # however many levels above the bottom-most child (leaf) node
# (leaf nodes are at height 1)Simply pass the head node as an argument to the TreePrint::tree_to_s method to convert the whole tree to a nicely formatted, multi-line string. You can include the TreePrint module to your class as well.
See examples for integration with a binary search tree class.
Running the example.rb in the examples directory produces the following output:
