MvL> I think Arash is pointing out that the first paragraph
MvL> right-adjusts in the Window, whereas the second paragraph
MvL> left-adjusts.
MvL> If you could read Farsi, you would probably also notice that
MvL> the order of words is incorrect in the second paragraph,
MvL> since the first word is on the left end of the line, so if
MvL> you read RTL, you start in the middle of a sentence
MvL> (depending on where your browser breaks the lines).
I see that now, thanks. Boy, Martin, I didn't know you read Farsi
too! :)
MvL> In the first paragraph, all is fine: the first word is on the
MvL> right end of the first line, and stays there no matter how
MvL> you resize the window. This is caused by the dir=3D"rtl" of th=
e
MvL> P element.
MvL> So, in short, you do need the dir attribute - the browser
MvL> does not automatically set the directionality of the
MvL> paragraph.
MvL> For Mailman, this means you need to augment all templates
MvL> appropriately - I guess this is usually done on the <html>
MvL> tag. If you ever generate the HTML tag without a
MvL> customization hook (e.g. as in htmlformat.Document.Format),
MvL> then this might cause a problem: you will need to inject
MvL> "DIR=3D'RTL'" there somehow. Alternatively, you'll have to mov=
e
MvL> the dir attribute further down, to, say, TITLE and BODY.
The templates should be easy, since you'd just add those to the fa
version. Here's a sketch of what Arash might want to hack together
for htmlformat.Document.Format():
- Add a dictionary to Defaults.py.in called LC_DIRECTIONS, where the
key is a language code and the value is a flag. I don't want to
change the interface for LC_DESCRIPTIONS.
- Add a function to Utils.py that returns the direction for a given
language code by looking up the language in LC_DIRECTIONS. The
default should be LTR so if there's no key in the dict, it's LTR.
- Add the appropriate dir attribute to the appropriate tag in Format()
based on the lookup. You probably should not add a dir attribute
for LTR.
That may be all you need, although check the archiver for other places
where <html> might be hardcoded.
