There's no bug number for this proposal?
This doesn't seem particularly useful. On any other distribution on the
planet, sensible-editor won't exist, so it doesn't make it easier for
upstream, and as far as the user is concerned it's not much better than,
ummm,
char *pch, buf[1000];
if ((pch = getenv("EDITOR"))) {
sprintf(buf, "%s filename.txt", pch);
} else {
sprintf(buf, "vi filename.txt", pch);
}
system(buf);
. So this seems to be extra work for absolutely no benefit to anyone.
OTOH, the above code fragment doesn't conform to policy, which demands:
Thus, every program that launches an editor or pager has to use the
EDITOR or PAGER environment variables to determine the editor/pager
the user wants to get started. If these variables are not set, the
programs `/usr/bin/editor' and `/usr/bin/pager' have to be used,
respectively.
On the other hand, sensible-editor doesn't look at /usr/bin/editor either,
which conflicts with what policy says a couple of paragraphs later:
If it is very hard to adapt a program to make us of the EDITOR and
PAGER variable, that program should be configured to use
`/usr/bin/sensible-editor' and `/usr/bin/sensible-pager' as editor or
pager program, respectively. These are two scripts provided in the
Debian base system that check the EDITOR and PAGER variables and
launches the appropriate program or falls back to `/usr/bin/editor'
and `/usr/bin/pager', automatically.
.
I wonder if:
* EDITOR and PAGER are set in /etc/environment or /etc/profile
or somewhere to /usr/bin/editor and /usr/bin/pager respectively,
by default.
* Programs should check $EDITOR and $PAGER if they need to fork
an editor or a pager, and try some other reasonable defaults if
those variables aren't set. /usr/bin/editor and /usr/bin/pager
being recommended, but /usr/bin/vi, /bin/vi, /usr/bin/less, etc
being allowed, since that's what happens on other systems.
* If they can't do this, they should call
/usr/bin/sensible-{editor,pager} which will do it for them.
mightn't be a better way of managing this.
