#2287: No simple way to make TurboGears 2 produce HTML

-------------------------+--------------------------------------------------
In TG 1.0, switching between HTML and XHTML output was the matter of only
one config setting, but in TG 2.0 this has become very difficult. By
default TG 2.0 produces XHTML (while TG 1.0 produced HTML by default) and
there is no clean and simple way to use HTML in TG 2.0.
Note that I'm not against using XHTML as the default, but there are many
good reasons to produce HTML instead of XHTML, so people should at least
be given the [http://www.htmlgoodies.com/beyond/xml/print.php/3669451
choice].
There are two problems:
1. Changing the output method of the default render function (using
Genshi) is not as straightforward as it should be (as discussed
[http://groups.google.com/group/turbogears/browse_thread/thread/7f65c32d4621a52e
here]).
2. Even if you change the default Genshi renderer, the ressource
injection of !ToscaWidgets will still use XHTML for CSS links, because it
uses the string.Template rendering engine with a hardcoded XHTML template
(as discussed [http://groups.google.de/group/toscawidgets-
discuss/browse_thread/thread/91765d109965ad2d here]).
My current solution is to add the following code to
`config/environment.py`:
{{{
# Make Genshi render HTML (instead of XHTML) by default:
_load_environment = load_environment
def load_environment(*args):
_load_environment(*args)
from genshi.output import DocType, HTMLSerializer
render_genshi = base_config.render_functions.genshi
def render_genshi_html(*args, **kwargs):
return render_genshi(method='html', *args, **kwargs)
base_config.render_functions.genshi = render_genshi_html
# Monkey-patch ToscaWidget so that it creates a valid HMTL link tag
# instead of a XHTML tag when injecting resources:
from tw.api import CSSLink
CSSLink.template = CSSLink.template.replace('/>', '>')
}}}
This solves the problem, but it is really ugly and complicated. Something
so basic should have a much simpler solution. I think this is an annoying
step backward in TG2 compared with TG1.
