Sure, just use the ":so otherexrc" command. I haven't posted this for a while, so here's my .exrc; it's something to stick in the faces of emacsoids, who think vi is not an extensible editor. Just remember: EMACS belongs in <sys/errno.h> :-) Now, it's true that it doesn't start up particularly quickly on diskless Suns, but what does? It works just fine on my Convex. :-) I've commented out a few things that won't work in all versions. There are pretty extensive comments, but you'll want to try them out to really appreciate the stuff. A couple of these are just for fun, but most are quite helpful. Some are really, really helpful. I've run this all through "cat -v" so that it gets there semi- intact, so you'll have to undo this. A problem is that there are some real carets in here. They are on these maps: \C \l ^X ^Y \r It should be obvious which are real. If you run the file through this filter: perl -pe 's/\^(.)/sprintf("%c",ord($1) &~ 0x40)/ge' It will uncat-v the whole thing, and then you should go fix up the five maps listed above. If you don't have perl (shame on you! :-) then you'll have do it by hand; that substitute doesn't work quite as well in sed. :-) --tom " tom christiansen's .exrc file <tchrist@convex.com> " " set terse " because we prefer terse error messages, set writeany autowrite " because we want to write out our file whenever we can, " like on a :tag, :stop, or :next set tabstop=8 " so tabs look right for us set shiftwidth=4 " so ^T and << are smaller set report=1 " so we our told whenever we affect more than 1 line set nomesg " because being talked to during an edit is aggravating set autoindent " so i don't have to tab in set redraw optimize " keep the screen tidy " " " INPUT MACROS that i always want active " map! ^Z ^[:stop^M " so i can stop in input mode. note that autowrite is set, so map! ^A ^[:stop!^M " will stop me without writing.
