Re: Converting emacs to xemacs

Peter> Is there any potted description of how to convert elisp Peter> programs written for emacs to run under xemacs? I have not seen such a thing, but I have made a hardcopy version of the GNU Emacs Lisp Reference and then used the online version of the XEmacs Lisp Reference in order to find the differences in behavior in one vs. the other. Even then I miss things when porting sometimes (I synchronized our browse-url.el with the FSF version some time back and ended up introducing breakage in the process, which sucked). Basically, I'd start out evaluating the file in XEmacs and then looking for breakage. Some conditionals with featurep forms should allow you to make a reasonable version of the file that will work in both worlds. Don't forget to test a lot. :-) In some cases, I've found it's better just to throw the stuff out and start all over. I'd hope that's not the case with the file you want to port. http://www.interhack.net/pubs/applying-reusable-to-env/ describes a case where I threw out the old stuff and completely replaced it with the new. It was a win all the way around in that case. I hope that helps. -- Matt Curtin cmcurtin(a)interhack.net http://www.interhack.net/people/cmcurtin/
