Everybody can write an add-on for Mozilla. But nobody (except a few experts) messes with redisplay. Redisplay is *hard*. There are very few redisplays capable of doing what Emacs can do. Emacs, XEmacs. *Maybe* Gecko (Mozilla) or Webkit (Safari). On the other hand, the way you write your post, I doubt it requires changes to redisplay, but I could be wrong. So I think you need to explain what it is you want to do. Note that Mozilla has a high-level language (XUL) for managing its display (and other aspects of user interface). Add-ons are written in that language. Well, so does Emacs: Emacs Lisp. > I do not know how redisplay of Mozilla works, but as time as new > add ons appear every day, that means that the system is very > standardized and easy to learn. Emacs is also standardized and easy to learn. There are just many fewer people interested in writing Lisp libraries than there are writing Mozilla add-ons.
