Draws ASCII trees.

Project description

Occasionally, you want things to look slightly pretty in the terminal. If trees are involved, give asciitree a shot!

Sample output

Here’s a code sample:

class Node(object):
    def __init__(self, name, children): = name
        self.children = children

    def __str__(self):

root = Node('root', [
    Node('sub1', []),
    Node('sub2', [
        Node('sub2sub1', [])
    Node('sub3', [
        Node('sub3sub1', [
            Node('sub3sub1sub1', [])
        Node('sub3sub2', [])

print draw_tree(root)

and its output:

  |  +--sub2sub1
     |  +--sub3sub1sub1


The module consists of a single public function, with the following signature:

draw_tree(node, child_iter, text_str)

where node is the root of the tree to be drawn, child_iter is a function that when called with a node, returns an iterable over all its children and text_str turns a node into the text to be displayed in the tree.

The default implementations of these two arguments retrieve the children by accessing node.children and simply use str(node) to convert a node to a string.

The resulting tree is drawn into a buffer and returned as a string.
