Getting started
---------------

.. _getting_started:

Usage is simple.

**Construction**

>>> from anytree import Node, RenderTree
>>> udo = Node("Udo")
>>> marc = Node("Marc", parent=udo)
>>> lian = Node("Lian", parent=marc)
>>> dan = Node("Dan", parent=udo)
>>> jet = Node("Jet", parent=dan)
>>> jan = Node("Jan", parent=dan)
>>> joe = Node("Joe", parent=dan)

**Node**

>>> print(udo)
Node('/Udo')
>>> print(joe)
Node('/Udo/Dan/Joe')

**Tree**

>>> for pre, fill, node in RenderTree(udo):
...     print("%s%s" % (pre, node.name))
Udo
├── Marc
│   └── Lian
└── Dan
    ├── Jet
    ├── Jan
    └── Joe

For details see Node_ and RenderTree_.

**Visualization**

>>> from anytree.exporter import DotExporter
>>> # graphviz needs to be installed for the next line!
>>> DotExporter(udo).to_picture("udo.png")

.. image:: http://anytree.readthedocs.io/en/latest/_images/udo.png

The DotExporter_ can be started at any node and has various formatting hookups:

>>> DotExporter(dan,
...             nodeattrfunc=lambda node: "fixedsize=true, width=1, height=1, shape=diamond",
...             edgeattrfunc=lambda parent, child: "style=bold"
... ).to_picture("dan.png")

.. image:: http://anytree.readthedocs.io/en/latest/_images/static/dan.png

There are various other Importers_ and Exporters_.

**Manipulation**

A second tree:

>>> mary = Node("Mary")
>>> urs = Node("Urs", parent=mary)
>>> chris = Node("Chris", parent=mary)
>>> marta = Node("Marta", parent=mary)
>>> print(RenderTree(mary))
Node('/Mary')
├── Node('/Mary/Urs')
├── Node('/Mary/Chris')
└── Node('/Mary/Marta')

Append:

>>> udo.parent = mary
>>> print(RenderTree(mary))
Node('/Mary')
├── Node('/Mary/Urs')
├── Node('/Mary/Chris')
├── Node('/Mary/Marta')
└── Node('/Mary/Udo')
    ├── Node('/Mary/Udo/Marc')
    │   └── Node('/Mary/Udo/Marc/Lian')
    └── Node('/Mary/Udo/Dan')
        ├── Node('/Mary/Udo/Dan/Jet')
        ├── Node('/Mary/Udo/Dan/Jan')
        └── Node('/Mary/Udo/Dan/Joe')

Subtree rendering:

>>> print(RenderTree(marc))
Node('/Mary/Udo/Marc')
└── Node('/Mary/Udo/Marc/Lian')

Cut:

>>> dan.parent = None
>>> print(RenderTree(dan))
Node('/Dan')
├── Node('/Dan/Jet')
├── Node('/Dan/Jan')
└── Node('/Dan/Joe')

**Extending any python class to become a tree node**

The enitre tree magic is encapsulated by NodeMixin_
add it as base class and the class becomes a tree node:

>>> from anytree import NodeMixin, RenderTree
>>> class MyBaseClass(object):  # Just an example of a base class
...     foo = 4
>>> class MyClass(MyBaseClass, NodeMixin):  # Add Node feature
...     def __init__(self, name, length, width, parent=None, children=None):
...         super(MyClass, self).__init__()
...         self.name = name
...         self.length = length
...         self.width = width
...         self.parent = parent
...         if children:
...             self.children = children

Just set the `parent` attribute to reflect the tree relation:

>>> my0 = MyClass('my0', 0, 0)
>>> my1 = MyClass('my1', 1, 0, parent=my0)
>>> my2 = MyClass('my2', 0, 2, parent=my0)

>>> for pre, fill, node in RenderTree(my0):
...     treestr = u"%s%s" % (pre, node.name)
...     print(treestr.ljust(8), node.length, node.width)
my0      0 0
├── my1  1 0
└── my2  0 2

The `children` can be used likewise:

>>> my0 = MyClass('my0', 0, 0, children=[
...     MyClass('my1', 1, 0),
...     MyClass('my2', 0, 2),
... ])

>>> for pre, fill, node in RenderTree(my0):
...     treestr = u"%s%s" % (pre, node.name)
...     print(treestr.ljust(8), node.length, node.width)
my0      0 0
├── my1  1 0
└── my2  0 2
