Hi
I'm not sure what reversing you get (the whole link? individual letters?),
but in case it helps here is some antediluvian code that I used to use many
years ago to get occasional Hebrew words in ordinary EmTeX. You would want
to put the back-to-front text in the \reversedtext macro at the end of the
code; and you would need to have \input pstricks somewhere in the header to
your file. (Note that 'gobbledtext' in the follwowing just gets swallowed
up - I've forgotten the ins and outs of this and think the code is a bit of
trickery derived from something Jonathan Fine produced, either publicly or
in a message to me.)
\def\processlist#1%
{%
\ifx #1\ \ \else
\ifx #1\sentinel \expandafter \sentinel \noexpand
\else
%\processitem
\flip #1\fi\fi
\processlist
}
\def \sentinel {\gobble\sentinel}
\def \gobble #1 {}
%where \processitem is up to you.
%Use as \processlistabcdefghij\sentinel
\def\flip#1{\psscalebox{-1 1}{#1\vrule height 0.8\baselineskip depth
0.2\baselineskip width0pt}}
\def\flipletter#1{\ifreverse \scalebox{-1 1}{#1}\else\relax\fi}
\def\reversedtext#1{\processlist #1\sentinel gobbledtext \hskip 0pt\ }
Example of usage:
Some stuff \reversedtext{turnitround}and some more stuff.
Note that the space following the reversed material is part of the
\reversedtext macro so that after the closing } you *don't* put in a space
(otherwise you'll get a double space in the output) - it seems quite hard to
insert a space if you don't incorporate it in the macro, but as I say I've
forgotten all the details. If you need spaces within the argument (I think
not?) they would have to be given explicitly with \
If you want an entire block reversed (not each letter one by one), just give
\input pstricks and then
\psscalebox{-1 1}{text to be reversed}
Hope this helps!

Right, IIRC, that was the conclusion we reached while ago, it can't but
be fixed in the engine itself.
Hmm. Well, I've almost got what I want by modifying my \hr macro like so:
\def\hr#1#2{%
\ifrtl\endR\fi
\special{pdf:bann <</Subtype/Link/BS
<</Type/Border/W 0.0 /S/S>>
/A << /S/URI/URI (#1)>> >>}
\special{pdf: bc [ 0 0 1 ]}{\bgroup #2 \egroup}\special{pdf: ec}
\special{pdf:eann}
\ifrtl\beginR\fi}
Note the '\ifrtl', which is a new conditional which must be set to
indicate LTR vs RTL. So I stop the RTL before doing the special, and
resume it when I'm done with the specials. That works /almost/ as I want.
The remaining problem is that the link text (#2 in the macro) is reversed,
e.g. LTR. Do you know of a TeX way to reverse the characters? I could
shell out to 'rev', but that would be a pretty severe hit since I have a
lot of links in my document. I suppose I could also just reverse the text
in the document so it shows in the correct direction, but that's not
likely to be easy to remember to do.
Unlike in Arabic, Hebrew has no connecting forms to worrry about -- so
simply printing the 'link text' should look ok (that text also has no
vowel points to complicate matters).
Best regards,
Ron
