I'm thinking about rewriting the low-level HTML tag generator in
WebHelpers2, and wondering if there's an existing library that would be
worth using in this HTML 5/Python 2.6+ world. Something to reimplement the
low-level make_tag function:
make_tag("a", "Click here", href="foo.html") =>
"<a href="foo.html">Click here.</a>"
The stdlib seems to only have ElementTree, which is overkill and not that
suited to making individual tags in isolation. The libraries on PyPI seem
to be very old, older than the WebHelpers implementation. So I'm looking
for something that's:
- In the stdlib, or small and with no esoteric dependencies.
- Fast.
- Without ancient HTML 4/3 clutter.
- Compatible with MarkupSafe and the ''.__html__()`` protocol.
Other desirable features:
- Knows about HTML 5's empty tags, boolean attributes, data attributes, etc.
- Can set characteristics at the class level, and is subclassable.
- Has a Tag class or equivalent for lazy stringification. This would allow
you to build up the attributes piecemeal, pass the tag to a template, and
it would stringify itself when str() or .__html__() is called. Possibly
caching the string.
Is there a library that does this or should I write it myself?
I'd also like feedback on another idea. I'm thinking about adding arguments
to build up the class attribute and style attribute piecemeal:
make_tag(..., classes=["foo", "bar"]) => ' ... class="foo bar"'
make_tag(..., styles=["margin:0", "padding: 1ex"]) => '...
style="margin:0; padding: 1ex")
Would this be useful to others? Would the names collide with any other
potential attributes? (I don't think so since HTML doesn't define "styles"
and "classes", and is unlikely to because of user confusion.) Is there a
better API? Are there any other attributes where this would be useful on?
Are there any other syntactic sugar patterns that would be helpful in a
Javascript-rich or HTML 5 application?
