Normal usage is rather straightforward (where ``text`` is page text):

>>> import mwparserfromhell
>>> wikicode = mwparserfromhell.parse(text)
>>> import mwparserfromhell
>>> wikicode = mwparserfromhell.parse(text)

``wikicode`` is a ``mwparserfromhell.Wikicode`` object, which acts like an
ordinary ``str`` object (or ``unicode`` in Python 2) with some extra methods.
For example::
>>> text = "I has a template! {{foo|bar|baz|eggs=spam}} See it?"
>>> wikicode = mwparserfromhell.parse(text)
>>> print(wikicode)
I has a template! {{foo|bar|baz|eggs=spam}} See it?
>>> templates = wikicode.filter_templates()
>>> print(templates)
['{{foo|bar|baz|eggs=spam}}']
>>> template = templates[0]
>>> print(template.name)
foo
>>> print(template.params)
['bar', 'baz', 'eggs=spam']
>>> print(template.get(1).value)
bar
>>> print(template.get("eggs").value)
spam
Since nodes can contain other nodes, getting nested templates is trivial::
>>> text = "{{foo|{{bar}}={{baz|{{spam}}}}}}"
>>> mwparserfromhell.parse(text).filter_templates()
['{{foo|{{bar}}={{baz|{{spam}}}}}}', '{{bar}}', '{{baz|{{spam}}}}', '{{spam}}']
For example:
>>> text = "I has a template! {{foo|bar|baz|eggs=spam}} See it?"
>>> wikicode = mwparserfromhell.parse(text)
>>> print(wikicode)
I has a template! {{foo|bar|baz|eggs=spam}} See it?
>>> templates = wikicode.filter_templates()
>>> print(templates)
['{{foo|bar|baz|eggs=spam}}']
>>> template = templates[0]
>>> print(template.name)
foo
>>> print(template.params)
['bar', 'baz', 'eggs=spam']
>>> print(template.get(1).value)
bar
>>> print(template.get("eggs").value)
spam
Since nodes can contain other nodes, getting nested templates is trivial:
>>> text = "{{foo|{{bar}}={{baz|{{spam}}}}}}"
>>> mwparserfromhell.parse(text).filter_templates()
['{{foo|{{bar}}={{baz|{{spam}}}}}}', '{{bar}}', '{{baz|{{spam}}}}', '{{spam}}']

You can also pass ``recursive=False`` to ``filter_templates()`` and explore
templates manually. This is possible because nodes can contain additional
``Wikicode`` objects::
>>> code = mwparserfromhell.parse("{{foo|this {{includes a|template}}}}")
>>> print(code.filter_templates(recursive=False))
['{{foo|this {{includes a|template}}}}']
>>> foo = code.filter_templates(recursive=False)[0]
>>> print(foo.get(1).value)
this {{includes a|template}}
>>> print(foo.get(1).value.filter_templates()[0])
{{includes a|template}}
>>> print(foo.get(1).value.filter_templates()[0].get(1).value)
template
``Wikicode`` objects:
>>> code = mwparserfromhell.parse("{{foo|this {{includes a|template}}}}")
>>> print(code.filter_templates(recursive=False))
['{{foo|this {{includes a|template}}}}']
>>> foo = code.filter_templates(recursive=False)[0]
>>> print(foo.get(1).value)
this {{includes a|template}}
>>> print(foo.get(1).value.filter_templates()[0])
{{includes a|template}}
>>> print(foo.get(1).value.filter_templates()[0].get(1).value)
template

Templates can be easily modified to add, remove, or alter params. ``Wikicode``
objects can be treated like lists, with ``append()``, ``insert()``,
``remove()``, ``replace()``, and more. They also have a ``matches()`` method
for comparing page or template names, which takes care of capitalization and
whitespace::
>>> text = "{{cleanup}} '''Foo''' is a [[bar]]. {{uncategorized}}"
>>> code = mwparserfromhell.parse(text)
>>> for template in code.filter_templates():
... if template.name.matches("Cleanup") and not template.has("date"):
... template.add("date", "July 2012")
...
>>> print(code)
{{cleanup|date=July 2012}} '''Foo''' is a [[bar]]. {{uncategorized}}
>>> code.replace("{{uncategorized}}", "{{bar-stub}}")
>>> print(code)
{{cleanup|date=July 2012}} '''Foo''' is a [[bar]]. {{bar-stub}}
>>> print(code.filter_templates())
['{{cleanup|date=July 2012}}', '{{bar-stub}}']
whitespace:
>>> text = "{{cleanup}} '''Foo''' is a [[bar]]. {{uncategorized}}"
>>> code = mwparserfromhell.parse(text)
>>> for template in code.filter_templates():
... if template.name.matches("Cleanup") and not template.has("date"):
... template.add("date", "July 2012")
...
>>> print(code)
{{cleanup|date=July 2012}} '''Foo''' is a [[bar]]. {{uncategorized}}
>>> code.replace("{{uncategorized}}", "{{bar-stub}}")
>>> print(code)
{{cleanup|date=July 2012}} '''Foo''' is a [[bar]]. {{bar-stub}}
>>> print(code.filter_templates())
['{{cleanup|date=July 2012}}', '{{bar-stub}}']

You can then convert ``code`` back into a regular ``str`` object (for
saving the page!) by calling ``str()`` on it::

>>> text = str(code)
>>> print(text)

>>> text == code

>>> text = str(code)
>>> print(text)
{{cleanup|date=July 2012}} '''Foo''' is a [[bar]]. {{bar-stub}}
>>> text == code
True

Likewise, use ``unicode(code)`` in Python 2.
