pkgcore is an alternative package manager for Gentoo that aims for high performance, extensibility, and a clean design. Written in Python, pkgcore also subsumes most of the functionality of the eix and layman repository management tools.
pkgcore is written and maintained by Gentoo developer Tim Harder (radhermit).
pkgcore is still experimental and care should be taken when updating a system
The the emerge command:
emerge --ask sys-apps/pkgcore
If there is no specific pkgcore configuration (that is /etc/pkgcore.conf or ~/.pkgcore.conf) it reads the Portage configuration and converts it transparently for use. For a detailed explanation of how the pkgcore specific configuration works see Pkgcore/Configuration.
Updating the system
For synchronizing the local copies of the Portage tree and any overlays the pmaint utility is used. Then pmerge is invoked to update all packages and clean superfluous packages.
pmerge --ask --upgrade --deep --newuse
pmerge --ask --clean --with-built-deps
Searching for a package
To search for a package use the pquery program:
pquery -nv <query>
For example to find some audio software for encoding ogg files one may use the following to find media-sound/vorbis-tools.
pquery -nv --description ogg 'media-sound/*'
Note the quotes around the extended atom to protect from expansion by the shell.
Installing a package
A package can be installed with pmerge:
pmerge --ask --verbose <atoms>
In our example this would be the following:
pmerge --ask --verbose media-sound/vorbis-tools
pmerge is intended to be compatible with portage. It should be possible to use both emerge and pmerge on the same system.
emerge --ask --depclean --verbose sys-apps/pkgcore
