However, if one has stan-based rather than file-based XHTML, it's neither documented nor obvious how this should be done. I've managed to get this far:

from nevow import stan ... _athena = stan.Proto ( 'athena:handler event="onkeypress" handler="keyPressed"' ) ... T.input ( type = "text", _class = "sw-input" ) [ _athena ]

stan.Proto takes a tag name, so you would really want just stan.Proto('athena:handler'). However, there's already one of these in athena, so you can just do: from nevow import stan, athena # ... T.input(type='text', _class='sw-input')[ athena.handler(event='onkeypress', handler='keypressed'] -- mithrandi, i Ainil en-Balandor, a faer Ambar

Thanks, Tristan; that's certainly a step forward: the tag is now being recognised and replaced. However, it's not quite perfect yet: the generated HTML is escaped:

_handler = athena.handler ( event = 'onkeypress', handler = 'keyPressed' ) ... T.input ( _class = "sw-input", type = "text" ) [ _handler ],

Results in:

<input type="text" class="sw-input" onkeypress="return Nevow.Athena.Widget.handleEvent(this, &quot;onkeypress&quot;, &quot;keyPressed&quot;);" />

Should I be wrapping it in anything else (T.raw()?).

Are you sure this is causing a problem? It looks correct to me. :) would seriously confuse an html parser. Jean-Paul

I am seeing the same behavior in my app, where I was working on implementing a feature similar to Tristan's. I'm seeing:

Now I'm just realizing what JP was referring to. That's definitely acceptable syntax, but it still doesn't seem to be working for me. Using this: T.div(render=T.directive('liveElement'))[ T.input(type="text", size=80, onKeyUp='Nevow.Athena.Widget.get (this).parse(event)') ] works, but this: T.div(render=T.directive('liveElement'))[ T.input(type='text', size=80)[athena.handler(event='onkeypress', handler='parse')]]) ] fails without generating any error. I guess I'm okay with the first version for my particular use-case, but I'd be interested to know if there's something obvious I'm missing, or other information I can supply. -phil

How does it fail? Can you throw together a minimal self-contained example? I use this in a lot of places and it works and as far as I understand there is no reason it shouldn't.

Here you go. At least, I hope I haven't broken it in some other way while whittling it down. twistd -noy stuff.py, then browse to http://localhost:8080 stuff.py as it stands it doesn't work. However, edit line 48 of stuff.py to read: docFactory = docFactoryJS instead of docFactory = docFactoryAthena and it starts working. I'm fully prepared for the possibility of eating humble pie over some typo, but if it is a typo, my eyes are incapable of seeing it :-) Regards, Ricky
