MarkupSafe

Implements a unicode subclass that supports HTML strings:

>>> from markupsafe import Markup, escape
>>> escape("<script>alert(document.cookie);</script>")
Markup(u'&lt;script&gt;alert(document.cookie);&lt;/script&gt;')
>>> tmpl = Markup("<em>%s</em>")
>>> tmpl % "Peter > Lustig"
Markup(u'<em>Peter &gt; Lustig</em>')

If you want to make an object unicode that is not yet unicode but don't want to lose the taint information, you can use the soft_unicode function:

>>> from markupsafe import soft_unicode
>>> soft_unicode(42)
u'42'
>>> soft_unicode(Markup('foo'))
Markup(u'foo')

Objects can customize their HTML markup equivalent by overriding the __html__ function:

>>> class Foo(object):
...  def __html__(self):
...   return '<strong>Nice</strong>'
...
>>> escape(Foo())
Markup(u'<strong>Nice</strong>')
>>> Markup(Foo())
Markup(u'<strong>Nice</strong>')

Since MarkupSafe 0.10 there is now also a separate escape function called escape_silent that returns an empty string for None for consistency with other systems that return empty strings for None when escaping (for instance Pylons' webhelpers).

If you also want to use this for the escape method of the Markup object, you can create your own subclass that does that:

from markupsafe import Markup, escape_silent as escape

class SilentMarkup(Markup):
    __slots__ = ()

    @classmethod
    def escape(cls, s):
        return cls(escape(s))
