Output Options

-1, --first

print the slot of the package

collapse multiple matching versions together

--attr attribute

print this attribute's value (can be specified more than once)

--force-attr attribute

like --attr but accepts any string as attribute name instead of only explicitly supported names

--one-attr attribute

print one attribute, suppresses other output

--force-one-attr attribute

like --one-attr but accepts any string as attribute name instead of only explicitly supported names

Usage

Another switch that could do with some extra explanation is --raw. Specifying --raw makes your configuration not affect the results. Example:

$ pquery --attr alldepends sys-apps/dbus --max -v
* sys-apps/dbus-0.62-r1
    description: A message bus system, a simple way for applications to talk
                 to each other
    homepage: http://dbus.freedesktop.org/
    depends: >=dev-libs/glib-2.6 || ( ( x11-libs/libXt x11-libs/libX11 )
                 virtual/x11 ) >=x11-libs/gtk+-2.6 >=dev-lang/python-2.4
                 >=dev-python/pyrex-0.9.3-r2 >=dev-libs/expat-1.95.8
                 dev-util/pkgconfig sys-devel/automake
                 >=sys-devel/autoconf-2.59 sys-devel/libtool
    rdepends: >=dev-libs/glib-2.6 || ( ( x11-libs/libXt x11-libs/libX11 )
                 virtual/x11 ) >=x11-libs/gtk+-2.6 >=dev-lang/python-2.4
                 >=dev-python/pyrex-0.9.3-r2 >=dev-libs/expat-1.95.8
    post_rdepends:

This is the highest unmasked package on the system. Also notice there are no references to USE flags or qt in the dependencies. That is because qt is not in USE for this configuration, so those dependencies do not apply.:

$ pquery --attr alldepends sys-apps/dbus --max -v --raw
* sys-apps/dbus-0.91
    description: Meta package for D-Bus
    homepage: http://dbus.freedesktop.org/
    depends:
    rdepends: >=sys-apps/dbus-core-0.91 python? (
                 >=dev-python/dbus-python-0.71 ) qt3? (
                 >=dev-libs/dbus-qt3-old-0.70 ) gtk? (
                 >=dev-libs/dbus-glib-0.71 ) !<sys-apps/dbus-0.91
    post_rdepends:

This version is in package.mask, and we can see the use-conditional flags now.

The --verbose or -v flag tries to print human-readable output (although some things like the formatting of depend strings need some improvement). Without -v the output is usually a single line per package in a hopefully machine-parseable format (usable in pipelines). There are some extras like --atom meant for shell pipeline use. If you have some useful shell pipeline in mind that pquery's output could be better formatted for please open an issue.

Adding short options is planned but there are some features to add first (want most of the features in place to avoid name clashes).

Examples

pquery

Comments

equery belongs /bin/ls

pquery --owns /bin/ls

equery check

not implemented (yet?)

equery depends python

pquery -I --revdep dev-lang/python

omitting -I makes it equivalent to equery depends -a

equery depgraph

not implemented (yet?)

equery files python

pquery --contents python

--contents is an output option, can be combined with any restriction

equery hasuse python

pquery -I --has-use python

equery list python

pquery -I '*python*'

this is in ExtendedAtomSyntax

equery size python

pquery --size python

equery uses python

pquery --attr use python

less information, but is an output option so mixes with any restriction

emerge -s python

pquery -vn '*python*'

emerge -S python

pquery -vnS python

searches through longdescription (from metadata.xml) too

no equivalent

pquery --license GPL-2 -I

list all installed GPL-2 packages

no equivalent

pquery --maintainer radhermit

list all packages that are maintained by radhermit

It can also do some things equery/emerge do not let you do, like restricting based on maintainer or herd and printing various other package attributes. See --help for those. If you miss a query open an issue.
