.SH NAME
aur \- helper tool for the arch user repository
.
.SH DESCRIPTION
.BR aur (1)
is the command wrapper for
.BR aurutils ,
a collection of scripts to automate usage of the Arch User
Repository. Different tasks such as update checks, package searching,
and computing dependencies are split to separate commands.
.PP
The chosen approach for managing packages is local pacman
repositories, instead of foreign (installed by
.BR "pacman \-U" )
packages.
.PP
A brief overview of local repositories is given in the
.B "CREATING A LOCAL REPOSITORY"
section.
.
.SH AUR COMMANDS
The below gives a short overview; see the respective documentation for
details.
.PP
.BR aur (1)
searches for commands in
.BR /usr/lib/aurutils/
by default, followed by

as set in the environment. A different path may be set at run-time

environment variable, for example
.IR /usr/local/lib/aurutils:/usr/lib/aurutils .

.SH EXIT STATUS
Programs follow a subset of errno(3), or preserve command status where
applicable.
.
.SH ENVIRONMENT
Environment variables for
.B aur
programs are prefixed with
.BR AUR .
Where applicable, standard variables such as
.B XDG_CONFIG_HOME
are respected. Variables supported by specific programs are listed
in their respective man pages (see
.BR "AUR COMMANDS" ).
.PP
Variables can be set in the user environment or in
.IR $XDG_CONFIG_HOME/aurutils/env ,
using a key/value format separated by newlines. For example:
.PP
.RS
.EX
AURDEST=/home/custompkgs
AUR_PACMAN_AUTH=sudo --askpass
AUR_PAGER=ranger
AUR_REPO=custom
.EE
.RE
.
.TP
.B AUR_DEBUG
Setting this variable enables debug mode (typically
.B xtrace
for
.BR bash (1)
scripts) in
.B aur
programs.
.
.TP
.B AUR_EXEC_PATH
The path in which
.B aur
searches for commands, prepended to
.BR $PATH .
Defaults to
.BR /usr/lib/aurutils .
.
.TP
.B NO_COLOR
Output colorization can be disabled by setting this environment
variable.
.
.SH CREATING A LOCAL REPOSITORY
A local repository may be configured directly in
.BR /etc/pacman.conf ,
or in a separate file specified with the
.B Include
directive. This section documents an example configuration; for
details, consult the
.BR pacman.conf (5)
man page.
.
.TP
.B Note:
Avoid naming the repository
.IR local ,
as this name is reserved by
.BR pacman (8).
.
.TP
.B Tip:
Consider separate repositories for different purposes, such as
version control packages.
.
.SS Pacman configuration
For the purposes of this example, we assume the local repository
.I custom
is located in
.IR /home/custompkgs .
.PP
Append a section for the local repository to
.IR /etc/pacman.conf
.PP
.EX
    [custom]
    SigLevel = Optional TrustAll
    Server = file:///home/custompkgs
.EE
.PP
Create the repository root and database:
.PP
.EX
    $ sudo install \-d /home/custompkgs \-o $USER
    $ repo\-add /home/custompkgs/custom.db.tar.gz
.EE
.PP
If built packages are available, add them to the database:
.PP
.EX
    $ cd /home/custompkgs
    $ repo\-add \-n custom.db.tar.gz *.pkg.tar*
.EE
.PP
Synchronize pacman:
.PP
.EX
    $ sudo pacman \-Syu
.EE
.
.SS CacheDir (optional)
When packages from a local repository are installed through
.BR "pacman \-S" ,
they are copied to a cache directory (usually
.IR /var/cache/pacman/pkg )
by
.BR pacman .
Besides using additional space, this may result in checksum mismatches
when rebuilding packages without increasing
.BR pkgrel .
(See GitHub issue #85)
.PP
To avoid this, set the repository path as a
.B pacman
.IR CacheDir ,
together with the
.B "CleanMethod = KeepCurrent"
setting to avoid unexpected deletion of built packages with
.BR "pacman \-Sc" .
.PP
This can be done by editing
.IR /etc/pacman.conf
as follows:
.PP
.EX
    [options]
    CacheDir = /var/cache/pacman/pkg /home/custompkgs
    CleanMethod = KeepCurrent
.EE
.PP
In addition,
.B SigLevel
should be set to
.B Never
or
.BR Always ,
if package signing is disabled or enabled, respectively. This avoids
.B pacman
copying over packages to the main
.BR CacheDir ,
if signature files are missing and
.B SigLevel = Optional
is set. (FS#71109)
.PP
Note that
.BR "pacman \-Scc"
will remove packages regardless of the
.B CleanMethod
setting.
.
.SH EXAMPLES
In this section, we assume that
.BR bash (1)
is the interactive shell.

.IR /usr/local/bin .
.PP
.BR aur\-gc
.PP
.EX
    #!/bin/bash
    # Remove unused build files in aur\-sync cache
    XDG_CACHE_HOME=${XDG_CACHE_HOME:\-$HOME/.cache}
    AURDEST=${AURDEST:\-$XDG_CACHE_HOME/aurutils/sync}

    # Assumes build files were retrieved through git(1)
    find "$AURDEST" \-name .git \-execdir git clean \-xf \e;

    # Print directories which do not contain a PKGBUILD file
    for d in "$AURDEST"/*; do

        paccache \-c "${repo_path%/*}" \-rvk0 "$@"
    done
.EE
.
.SS Using third-party helpers
Repository packages can be "made foreign" by temporarily removing the
repository from the pacman configuration. This can be used with programs
that support the
.B PACMAN
environment variable and check foreign packages for AUR updates.
.PP
For example, create the
.I mypacman
script in
.IR /usr/local/bin/mypacman :
.PP
.EX
    #!/bin/sh
    pacman \-\-config=/usr/share/devtools/pacman\-extra.conf "$@"
.EE
.PP
and point the
.B PACMAN
variable towards it:
.PP
.EX
    $ export PACMAN=/usr/local/bin/mypacman
.EE
