Initially I was hoping that major sites would put some more or less unique id attribute in their html or body elements, but it seems we can't rely on that. Do other browsers support something similar? Johannes

I've just pushed some changes, which will result in a broken line, which is OK. With no images shown, the column is somehow still too narrow, but the current release of dillo renders it too large.

You would need to do the setNonCssHint() before the first call to getStyle() on that element. So basically you would need to somehow remember the language for each element and then reload and set the appropriate language for the element - but I agree that that's not really elegant. > > I've tried: > > html->styleEngine->setNonCssHint( > PROPERTY_X_LANG, CSS_TYPE_STRING, html->lang); > > which seems to set it for the current element only. > > and > > html->styleEngine->restyle (); > > with no good result. Yeah, I fear restyle() does not what you need here. For now we could simply expose x-lang to the css parser, so you can at least set a reasonable default (e.g. body { x-lang:"en" } )in your ~/.dillo/style.css (see attached patch against dillo_hyphenation).

Several sites I visit don't trigger hyphenation because they lack the "lang" attribute. I'm experimenting with a very simple language guess routine, to get an idea of how it could help in this regard. @Johannes, This function samples text from the parser, and it may fall anywhere on the CSS tree. How can I set it for the HTML element so it is inherited from there? I've tried: html->styleEngine->setNonCssHint( PROPERTY_X_LANG, CSS_TYPE_STRING, html->lang); which seems to set it for the current element only. and html->styleEngine->restyle (); with no good result. TIA. -- Cheers Jorge.-
