[gentoo-user] where is the functionality of etcat

[Rudmer van Dijk]

etcat is deprecated in favor of equery but equery does not have a 
functionality like `etcat -v <package>` (listing all available versions of a 
package). I used it quite often and have been struggling with equery ever 
since etcat is deprecated... Are there plans to build this functionality into 
equery? if not, why??

Possibly because you can do the same with eix (emerge eix):

 eix gnome-games
* gnome-extra/gnome-games
     Available versions:  1.4.0.3-r3 2.4.2 2.6.2 2.8.1 2.8.1-r1 2.8.2
2.8.3 2.10.0 ~2.10.1
     Installed:           2.10.1
     Homepage:            http://www.gnome.org/
     Description:         Collection of games for the GNOME desktop

* gnome-extra/gnome-games-extra-data
     Available versions:  2.8.0 2.10.0
     Installed:           2.10.0
     Homepage:            http://www.gnome.org/
     Description:         Optional additional graphics for gnome- games


If that's of any help to you :-) .

It is already in there, people just tend to overlook it ;-) Run
"equery list -p package", for more information run "equery list --help"
or generally "equery <command> --help". If you run "equery --help" you
will notice that equery has global options and local options which do
some nice stuff.

Cheers,
Renat

thanks! I should have RTFM better than I did...

Holly: eix is probably not it, since it looks like it does not show the 
availability of the package (masked+keyword), but thanks for the suggestion!

Actually, it most certainly does; keyworded packages are shown in brown
with a ~ in front, masked packages are listed in red with a [M] in front.

Of course you can use what suits you best; just wanted to clear up the
misconception.

I haven't seen anyone post this script as yet.  It's by ciaranm and is
very useful when people ask on irc why a certain package version can't
be installed on their arch.

Sample output:
tom@tom ~ 0 0.67 $ eshowkw
gnome Keywords for gnome-base/gnome:

nice!
don't think it is really useful for me, I have two archs (amd64 and x86) but 
have good access to both machines. if you maintain more archs than this can 
be very usefull. Is this in some (dev-)package? maybe something for 
gentoolkit??

Well 'eix zoneminder' shows '~0.9.12  ~1.21.2'
both in brown.

emerge -s zoneminders shows
that it is masked in red and only 1.21.2. is available.

Maybe my color scheme is messed up?

According to packages.gentoo.org, both zoneminder 0.9.12 and 1.21.2 are
keyword masked, so the output is correct (for x86).

Esearch shows only the last version, and doesn't distinguish between
hard and keyword masking; perhaps emerge -s is the same.

Also, it helps to remember to do an update-eix after an esync, so that
new or updated packages are added to the eix database.

Other than that, I don't see a problem.

Doesn't 'equery list -p <package>' do what you want?  

$ equery list -p gentoo-sources
