.Ar ACTION
.Op ARGUMENTS
.Sh DESCRIPTION
The
.Nm
utility provides various utilities for interacting with XBPS and XBPS packages.
.Sh ARGUMENT TYPES
.Ss BINPKG
A
.Ar binpkg
argument is a string of the format
.Em <pkgname>-<version>_<revision>.<arch>.xbps ,
like the filename of a binary package.
.Ss PKGVER
A
.Ar pkgver
argument is a string of the format
.Em <pkgname>-<version>_<revision> ,
like the
.Em pkgver
property.
.Ss PKGPATTERN
A
.Ar pkgpattern
argument is package expression specifying a package name and version separated
by any of the following version comparators:
.Pp
.Bl -tag -width xx -compact
.It Sy <
less than
.It Sy >
greater than
.It Sy <=
less or equal than
.It Sy >=
greater or equal than
.Pp
.El
Example:
.Dq Sy foo>=2.0 .
.Sh OPTIONS
.Bl -tag -width -x
.It Fl C, Fl -config Ar dir
Specifies a path to the XBPS configuration directory.
If the first character is not '/' then it's a relative path of
.Ar rootdir .
.It Fl d, Fl -debug
Enables extra debugging shown to stderr.
.It Fl h, Fl -help
Show the help message.
.It Fl r, Fl -rootdir Ar dir
Specifies a full path for the target root directory.
.It Fl V, Fl -version
Show the version information.
.El

.Sh EXAMPLES
Compare package versions:
.Pp
.Dl $ xbps-uhelper cmpver 'foo-1.0_1' 'foo-2.1_1'
.Dl $ xbps-uhelper cmpver 1.0 2.1
.Pp
Get the package name for dependency pattern
.Dq foo>=0 :
.Pp
.Dl $ xbps-uhelper getpkgdepname 'foo>=0'
.Pp
Get the version expression for the dependency pattern
.Dq foo>=0 :
.Pp
.Dl $ xbps-uhelper getpkgdepversion 'foo>=0'
.Pp
Get the package name for pkgver
.Dq foo-2.0_1 :
.Pp
.Dl $ xbps-uhelper getpkgname foo-2.0_1
.Pp
Get the revision for pkgver
.Dq foo-2.0_1 :
.Pp
.Dl $ xbps-uhelper getpkgrevision foo-2.0_1
.Pp
Get the version for pkgver
.Dq foo-2.0_1 :
.Pp
.Dl $ xbps-uhelper getpkgversion foo-2.0_1
.Pp
Check if the pkgver
.Dq foo-1.0_1
matches the dependency pattern
.Dq foo>=1.0 :
.Pp
.Dl $ xbps-uhelper pkgmatch foo-1.0_1 'foo>=1.0'
.Pp
Get the version for the installed package
.Dq foo :
.Pp
.Dl $ xbps-uhelper version foo
.Pp
Get the names of packages from a list of pkgvers:
.Pp
.Dl $ xbps-query -Rp pkgver -s foo | cut -d: -f1 | xargs xbps-uhelper getpkgname
.Pp
Get the names of dependencies for a package:
.Pp
.Dl $ xbps-query -Rp run_depends xf86-video-amdgpu | xargs xbps-uhelper getname
.Sh ENVIRONMENT
.Bl -tag -width XBPS_TARGET_ARCH
.It Sy XBPS_ARCH
Overrides
.Xr uname 2
machine result with this value.
Useful to install packages with a fake
architecture.
.It Sy XBPS_TARGET_ARCH
Sets the target architecture to this value.
This variable differs from
.Sy XBPS_ARCH
in that it allows you to install packages partially, because
configuration phase is skipped (the target binaries might not be compatible with
the native architecture).
.El
.Sh FILES
.Bl -tag -width /var/db/xbps/.<pkgname>-files.plist
.It Ar /etc/xbps.d
Default configuration directory.
.It Ar /usr/share/xbps.d
Default system configuration directory.
.It Ar /var/db/xbps/.<pkgname>-files.plist
Package files metadata.
.It Ar /var/db/xbps/pkgdb-0.38.plist
Default package database (0.38 format). Keeps track of installed packages and properties.
.It Ar /var/cache/xbps
Default cache directory to store downloaded binary packages.
