[gentoo-user] portage wants to remove less and nano

[Niccolò Belli]

Here is after an emerge -av --depclean:

!!! 'app-editors/nano' (virtual/editor) is part of your system profile. 
 

!!! Unmerging it may be damaging to your system. 
 

 
 

 
 

  app-editors/nano
     selected: 2.2.5
    protected: none
      omitted: none

!!! 'sys-apps/less' (virtual/pager) is part of your system profile. 
 

!!! Unmerging it may be damaging to your system. 
 

 
 

 
 

  sys-apps/less
     selected: 441
    protected: none
      omitted: none



Portage version is 2.2.0_alpha62.

This is somewhat surprising, but intended and correct, it has been
discussed here some months ago. Just add those to your world file (using
emerge -n).

Yes, that is a known issue. Just add nano and less to @world with
emerge --noreplace app-editors/nano sys-apps/less
Or you could just emerge a different editor and pager. If you have
something else you can put in EDITOR and PAGER, you don't need those
packages and that is why portage no longer requires you to have them
installed.

Weird.  dispatch-conf certainly needs 'less'.  Why isn't it a dep?

No. It needs a pager.

Because dispatch-conf can use any pager.

Best,

One would think that if it is the selected and only one installed, it 
wouldn't try to remove it.  Isn't this what virtuals are for?  Portage 
needs one pager from the following list and as long as one is installed, 
portage is happy and doesn't try to remove it.

I know, this has been discussed and the devs still let it do this. < sighs >

That's how it works with regards to virtuals. It will only remove 'less'
if you have some other pager installed.

It currently *will* remove 'less' while it's eselected as the pager.
There's an underwhelming bug for this:

Didn't we thrash this one to death already 2 months ago?

Wasn't Zac's response that virtuals are inappropriate in the system set?

It's strange, there was no defaults editor and pager...

laptop ~ # eselect editor list && eselect pager list
Available targets for the EDITOR variable:
   [1]   /bin/nano
   [2]   /usr/bin/ex
   [3]   /usr/bin/vi
   [ ]   (free form)
Available targets for the PAGER variable:
   [1]   /bin/more
   [2]   /usr/bin/less
   [ ]   (free form)

laptop ~ # eselect editor show
EDITOR variable in profile:
   (none)

laptop ~ # eselect pager show
PAGER variable in profile:
   (none)


I'm pretty sure I never unset them...

Most likely you've never set them. Use 'eselect editor set X' where X
is 1 for nano, 2 for ex, and 3 for vi etc.

Shouldn't it ship with a default setting? Anyway even after setting a 
default, portage still wants to remove both less and nano. I had to put 
them in the world set.

I'll chime in.  I know this has been discussed so many times... but it
seems the discussion recurs.

You *can* get away with not putting virtuals in your world file, even
with the new portage behavior.  The trick is to not have any other
package satisfy the virtual.  For example, I use most as my pager and
gvim as my editor.  I uninstalled nano because I can't stand it and
never use it.  I also uninstalled less because I use most.  My world
file has neither most nor gvim in it, but because nothing else satisfies
the dependencies for virtual/pager and virtual/editor then they don't
get depclean'ed.

Of course this won't work for everyone.  If you have to have 2 pagers
installed, for example. Where I think some people will come into a
problem is with sys-apps/util-linux[ncurses].  This satisfies the
virtual/pager dep so it may want to clean sys-apps/more.  I don't have
the "ncurses" flag set for util-linux, so I don't have that issue.

Anyway a lot of people don't like the "new" behavior (which isn't really
new anymore).  I can't say I'm enthused about the change, but if you
think about (for a while) it makes sense, and it's not like it's going
to kill you to put nano/more/whatever in your world file.

I didn't pay too much attention back then, but for your second question,
these are all @system:

*virtual/dev-manager
*virtual/editor
*virtual/libc
*virtual/man
*virtual/os-headers
*virtual/package-manager
*virtual/pager
*virtual/ssh
