Kind of like htmlgen, only much simpler. The only important symbol
that is exported is ``html``.
This builds ElementTree nodes, but with some extra useful methods.
(Open issue: should it use ``ElementTree`` more, and the raw
``Element`` stuff less?)
You create tags with attribute access. I.e., the ``A`` anchor tag is
``html.a``. The attributes of the HTML tag are done with keyword
arguments. The contents of the tag are the non-keyword arguments
(concatenated). You can also use the special ``c`` keyword, passing a
list, tuple, or single tag, and it will make up the contents (this is
useful because keywords have to come after all non-keyword arguments,
which is non-intuitive). Or you can chain them, adding the keywords
with one call, then the body with a second call, like::
>>> print html.a(href='http://yahoo.com')('')
<Yahoo>
Note that strings will be quoted; only tags given explicitly will
remain unquoted.
If the value of an attribute is None, then no attribute
will be inserted. So::
>>> print html.a(href='http://www.yahoo.com', name=None,
... c='Click Here')
Click Here
If the value is None, then the empty string is used. Otherwise str()
is called on the value.
``html`` can also be called, and it will produce a special list from
its arguments, which adds a ``__str__`` method that does ``html.str``
(which handles quoting, flattening these lists recursively, and using
'' for ``None``).
``html.comment`` will generate an HTML comment, like
``html.comment('comment text')`` -- note that it cannot take keyword
arguments (because they wouldn't mean anything).
Examples::
>>> print html.html(
... html.head(html.title("Page Title")),
... html.body(
... bgcolor='#000066',
... text='#ffffff',
... c=[html.h1('Page Title'),
... html.p('Hello world!')],
... ))
Page TitlePage Title
Hello world!
>>> print html.a(href='#top')('return to top')
return to top
