-class Markup(unicode):
- r"""Marks a string as being safe for inclusion in HTML/XML output without
- 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 &lt;em&gt;World&lt;/em&gt;!')
-
- 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 &amp; bar</em>')
- >>> strong = Markup("<strong>%(text)s</strong>")
- >>> strong % {'text': '<blink>hacker here</blink>'}
- Markup(u'<strong>&lt;blink&gt;hacker here&lt;/blink&gt;</strong>')
- >>> Markup("<em>Hello</em> ") + "<foo>"
- Markup(u'<em>Hello</em> &lt;foo&gt;')
