Hi, I am writing to ask whether anyone on this list knows about any built in right-to-left support for Groff (without having to resort to hacks like using sed to reverse streams of characters)[1]. One of the reasons I mention this, is that there was a document or a mini solution (perhaps?) provided on the groff mailing list a number of years back - but trying to search the web for modern and relevant information seems to be fraught with the wrong answers (or just bad info).
There was, for example, one solution suggested in 2006, see: http://lists.gnu.org/archive/html/groff/2006-12/msg00018.html But it's not clear whether a) this is the only solution and b) if there's a coded version of this solution. Now I do appreciate that PDF and Postscript is, of course, left-to-right oriented. I mean, we have the ability in PDF to just write: T* (Hello World) Tj to obtain a line of text reading "Hello World" - of course such output won't be aligned beautifully. Part of the other issue is that il8n means that UTF 8 (or unicode) is now supported by our systems and - for example - typing in Hebrew in HTML (when using unicode) forces this to output automatically. (Naturally there can be some issues with potentially English styling like full stops etc.) But, so far as I can tell, whilst advances like mom for groff seem to make it easy to use - plus all the other drawing and other graphing languages that can be used together with Groff, there seems to be some RTL support missing. (That is to say, in HTML, Unicode Hebrew letters automatically face the right way (although certain English punctuation marks might not without coaxing)). Thank you for your help, Russell N Hyer Maths Student/Geek/Part time human [1] One semi effective way is to use the bidiv programme for Hebrew text (but this does kinda suggest that the current system (or my setup) is slightly misconfigured for RTL languages; of course in such a setup bidiv becomes yet another pre-processor and you also need to strip the additional white spacing.)
