- Description
MarkupSafe ========== Implements a unicode subclass that supports HTML strings: >>> from markupsafe import Markup, escape >>> escape("<script>alert(document.cookie);</script>") Markup(u'<script>alert(document.cookie);</script>') >>> tmpl = Markup("<em>%s</em>") >>> tmpl % "Peter > Lustig" Markup(u'<em>Peter > 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))
