Anything that provides vi should out of compability reasons also provide
ex.

Now, why isnt this discussion on -dev?

In principle, I don't have a problem with this, but I have a couple
questions:

1. Does having a virtual require that only one of the options is
   installed at a time?  I recall this being the case with
   ssmtp/postfix/etc, but maybe that's specific to those ebuilds.
   I wouldn't want Gentoo to be restricted to a single vi-clone on a
   system.

2. What are the builds that require ex?  That's a pretty strange
   requirement, to be honest.  Most builds I've seen require ed for
   non-interactive editing, not ex.

3. What about the case where you install vim, then install nvi, then
   uninstall nvi?  In that case /usr/bin/ex will disappear from the
   system (because the files conflict between packages), but the virtual
   will still be "satisfied".

4. What are the ebuilds that provide ex?  At first glance, I only see
   nvi and vim.

A Makefile generation script within the mozilla build required it, but I
decided adding two dependencies just to make a Makefile which isn't
specific to the user's system was overcomplicating matters.

Also, I noticed earlier the presence of virtual/editor, which nvi/vim
can satisfy, so I don't know how much utility virtual/ex will serve...

No , those builds also -conflict- with the virtual, to prevent any other
thing that satisfies said virtual from working.

This is a hairy issue which probably should be fixed within portage
(sanity check of some sort??  check target of symlinks perhaps?)

classic vi do that as well.

Hehe, that one didn't turn up with "ls -d */?vi*" (of course).  There's
also elvis and vile.  I guess there's quite a few that would satisfy 
virtual/ex, but I'm still hesitant to add it for a single questionable
build.

Dubiously yours,

Oh, that I can agree on, especially since it isn't needed anymore
(according to  mozilla changelogs )

But, nonetheless its a functionality that a lot of packages actually
supply, and I think they are all quite compatible (no, I dont use ex
myself very often... do you folks? ;)

let this thread fall I think...  until next time ;)

Are you saying that you're no longer pursuing virtual/ex?
