[gentoo-dev] new-style virtual/editor

[-- Attachment #1.1: Type: text/plain, Size: 675 bytes --]

Hi,

about 26 ebuilds have a PROVIDE=virtual/editor.  Those could be
transformed to a new-style virtual, which is really simple.  According
to zmedico and genone the impact of just commiting the virtual would be
low.  But I'd like to hear some comments on it.  If noone objects I
will commit it next week (Monday probably) and remove all PROVIDE
lines.  Eventually I will check profiles, too, and file bugs when
unsure what the intended behaviour?  Or anyone objections about me
touching his profiles.

How many packages depend on virtual/editor? Should it be a virtual at 
all?

Thanks,

<Tester_> !rdep virtual/editor
<jeeves> virtual/editor <- app-admin/sudo sys-process/fcron

I think the answer is none that really should, I would favor just
removing virtual/editor.

Does it really depend on it ? Or is it just a convenient dep so its
installed as part of the stage1 ? Why not just put nano in the system
(which is was gets pulled into the stages anyway).

I see that both sudo and fcron, while they have some versions that
depend on virtual/editor actually hardcode nano as the default.

The system set depends on it, and last I knew didn't allow for any-of
deps.

Ehh... "system" also requires it.  Removing the virtual means everybody,
no matter what, will get nano and won't be able to remove it without
portage bitching up a storm.  Currently, you can replace nano with any
editor that meets the virtual and it'll satisfy the system target.

For the fcron dependency, see https://bugs.gentoo.org/149376#c15 and
onward.

Couldn't people just profile/package.provided or profile/packages it, as 
I used to do with ssh (which apparently isn't a system dependency any 
longer, maybe omitted just on desktop profiles?) and still do for 
busybox, as neither is necessary or useful on my system, at least not to 
the point of justifying future upgrade hassles on a from-source 
distribution like Gentoo.

As for editor, even where people have an alternative system default 
editor, nano is extremely useful as a self-documented, small, low-
dependency fallback (for which it'd be more useful if it were compiled 
static, is it?).

Earlier in my Linux life I ended up in a situation where I had no working 
interactive editor at all, or at least none I was aware of (I later found 
they shipped a static vim-minimal as an emergency fallback editor, but I 
had no way of knowing it at the time)!  It's not a pleasant situation to 
be in, especially when you know all you have to do to get back to a 
working system is edit a single line in a single file -- only you can't 
do it without an editor!  Luckily, I remembered sed, and the sed appendix 
in the back of the "Linux in a Nutshell" book I still keep within easy 
reach to this day.  I'd never used sed before, but that day i had a crash-
course, and yes, I did manage to use it to get a working system back! =8^)

So yes, I definitely appreciate nano's role as low-dep fallback editor, 
and deliberately keep it on the system for exactly that reason.  I think 
I've used it twice in that role in the years I've been on Gentoo, during 
which I've upgraded or otherwise remerged it several times, but it's an 
easy and very quick emerge (unlike say, busybox), and VERY handy when 
nothing else works, so it's worth it.

>From here, therefore, a hard system dependency on nano doesn't look so 
bad, particularly since Gentoo already provides reasonable, easy and 
documented ways to avoid that dependency if one should prefer to.

A lot more applications need it, see subversion and cvs, which invoke 
$EDITOR.

I think you missed the train when someone mentioned we put an editor
in system, thus making one always available.

I thought this discussion was going into a direction that had the system 
dependency removed. I guess I was mistaking.

if it's part of the "system" target, then it's a pita for people to switch 
editors ... `emerge vim && emerge -C nano` wont work anymore

if it's part of the "build" target (meaning it goes into stage1 but isnt part 
of "system"), then it'll get cleaned by default when doing something simple 
like `emerge depclean`

it doesnt matter to me whether ebuilds do PROVIDE or a new style virtual, 
whatever floats your boat i guess

 New-style virtual in the tree with nearly 30 packages in
RDEPEND...:)...we added some that were not providing it until now.
Profiles fixed (except selinux/2005.1/mips) and ebuilds cleaned-up.
Thanks to ulm for the help.  So if you have a text-mode editor not in
there, just add it to the virtual or file a bug.  I put emacs, xemacs,
vim teams and base-system into metadata.xml as maintainers.
