needing to be escaped. This implements the `__html__` interface a couple
of frameworks and web applications use. :class:`Markup` is a direct
subclass of `unicode` and provides all the methods of `unicode` just that
it escapes arguments passed and always returns `Markup`.
The `escape` function returns markup objects so that double escaping can't
happen.
The constructor of the :class:`Markup` class can be used for three
different things: When passed an unicode object it's assumed to be safe,
when passed an object with an HTML representation (has an `__html__`
method) that representation is used, otherwise the object passed is
converted into a unicode string and then assumed to be safe:
>>> Markup("Hello <em>World</em>!")
Markup(u'Hello <em>World</em>!')
>>> class Foo(object):
... def __html__(self):
... return '<a href="#">foo</a>'
...
>>> Markup(Foo())
Markup(u'<a href="#">foo</a>')
If you want object passed being always treated as unsafe you can use the
:meth:`escape` classmethod to create a :class:`Markup` object:
>>> Markup.escape("Hello <em>World</em>!")
Markup(u'Hello <em>World</em>!')
Operations on a markup string are markup aware which means that all
arguments are passed through the :func:`escape` function:
>>> em = Markup("<em>%s</em>")
>>> em % "foo & bar"
Markup(u'<em>foo & bar</em>')
>>> strong = Markup("<strong>%(text)s</strong>")
>>> strong % {'text': '<blink>hacker here</blink>'}
Markup(u'<strong><blink>hacker here</blink></strong>')
>>> Markup("<em>Hello</em> ") + "<foo>"
Markup(u'<em>Hello</em> <foo>')
