[gentoo-user] get unversioned list of installed packages without eix or esearch

I know that I can get a list of installed packages without their version 
numbers with eix:

# eix -nI --format '<category>/<name>' | \
	grep -vr '^$\|^\[[0-9]*\]\|^Found\ [0-9]*'

This is probably possible with esearch too. But does anybody know of a way to 
get it with portage, bash or gentoolkit?

I was of course considering something like this:

# cd /var/db/pkg && ls * | ${some_magic_regular_expression_to_remove_version}

But I have found it impossible to make a regular expression that does break 
for at least one of those:

media-fonts/font-adobe-100dpi-1.0.0
media-fonts/font-adobe-75dpi-1.0.0
media-fonts/font-adobe-utopia-type1-1.0.1
media-libs/jpeg-6b-r7
net-misc/cisco-vpnclient-3des-4.8.00.0490
sys-apps/portage-2.1.1_pre1-r2
sys-fs/udev-090
sys-fs/udev-090-r1
sys-libs/libstdc++-v3-3.3.6
sys-libs/timezone-data-2006g

Which are:

media-fonts/font-adobe-100dpi
media-fonts/font-adobe-75dpi
media-fonts/font-adobe-utopia-type1
media-libs/jpeg
net-misc/cisco-vpnclient-3des
sys-apps/portage
sys-fs/udev
sys-fs/udev
sys-libs/libstdc++-v3
sys-libs/timezone-data

Any ideas?

Well, there is probably a better way to write this script, but here is
a method that will do it with bash.  The idea is for each package in
portage, to determine whether that is installed or not.  This seems a
bit easier than working backwards from the installed package database:

cd /usr/portage
find . -name "*.ebuild" | sed -e 's/\.\///g' | while read ebuild; do
    pkg=`dirname $ebuild`
    category=`dirname $pkg`
    pkgdir=`basename $ebuild .ebuild`
    test -d /var/db/pkg/$category/$pkgdir && echo $pkg
done | sort

This works, but it does seem to take a long time!

Probably because of all those dirnames and basename calls. Try:

cd /usr/portage
find . -name "*.ebuild" | sed -e 's/\.\///g' | while read ebuild; do
	pkg=${ebuild%/*}
	category=${pkg%/*}
	pkgdir=${ebuild##*/} ; pkgdir=${pkgdir%.ebuild}
	[[ -d "/var/db/pkg/$category/$pkgdir" ]] && echo "$pkg"
done | sort

It works on the examples you provided. I don't think anything in the tree 
uses '-' in the version number, unless it's a case of '-rN'. But you never 
know, of course, so I always double check all package names I ever filter 
through anything.

This was exactly what I was looking for. Since the following command did not 
produce any relevant output I can confirm that this works for everything 
currently in portage.

# cd /usr/portage && \
	find . -name '*.ebuild' | sed -e 's/\.ebuild$//' | \
	awk -F/ '{print $2"/"$4}' | sed -r 's/-[^-]+(-r[0-9]+)*$//' | \
	awk -F/ '{system("eix -C "$1" -e "$2" -c | grep -q ^Found\\ 1\\ matches || \
	 echo "$0)}'

Thank you to everyone who replied. :)

Just pipe the above list through the attached script.
