=head1 NAME
expac - alpm data extraction utility
=head1 SYNOPSIS
Usage: I<expac> [options] E<lt>formatE<gt> targets...
=head1 DESCRIPTION
expac is a data extraction tool for alpm databases. It features printf-like
flexibility and aims to be used as a simple tool for other pacman based
utilities which don't link against the library. It uses pacman.conf as a config
file for locating and loading your local and sync databases.
Invoking expac consists of supplying a format string, which is generally
described by one to many of the formatting tokens (see the B<FORMATTING>
section), any relevant options and zero to many targets. The format string
B<must> be the first non-option argument. Targets can be a simple package name,
a query string (in the case of a search), or in repo/package syntax when the
-sync option is supplied.
=head1 OPTIONS
=over 4
=item B<-Q, --query>
Search the local database for provided targets. This is the default behavior.
=item B<-S, --sync>
Search the sync databases for provided targets.
=item B<-s, --search>
Search for packages matching the strings specified by targets. This is a
boolean AND query and regex is allowed.
=item B<-g, --group>
Return packages matching the specified targets as package groups.
=item B<--config> <file>
Read from I<file> for alpm initialization instead of I</etc/pacman.conf>.
=item B<-H, --humansize> <size>
Format package sizes in SI units according to I<size>. Valid options are:
B, K, M, G, T, P, E, Z, Y
=item B<-1, --readone>
Stop searching after the first result. This only has an effect on -S operations
without -s.
=item B<-d, --delim> <string>
Separate each package with the specified I<string>. The default value is a
newline character.
=item B<-l, --listdelim> <string>
Separate each list item with the specified I<string>. Lists are any interpreted
sequence specified with a capital letter. The default value is two spaces.
=item B<-p, --file>
Interpret targets as paths to local files.
=item B<-t, --timefmt> <format>
Output time described by the specified I<format>. This string is passed directly
to strftime(3). The default format is %c.
=item B<-v, --verbose>
Output more. `Package not found' errors will be shown, and empty field values
will display as 'None'.
=item B<-h, --help>
Display the help message and quit.
=back
=head1 FORMATTING
The format argument allows the following interpreted sequences:
%B backup files
%C conflicts with
%D depends on
%E depends on (no version strings)
%F files (only with -Q)
%G groups
%L licenses
%N required by
%O optional deps
%o optional deps (no descriptions)
%P provides
%R replaces
%S provides (no version strings)
%a architecture
%b build date
%d description
%f filename (only with -S)
%g base64 encoded PGP signature (only with -S)
%h sha256sum
%V package validation method
%i has install scriptlet (only with -Q)
%k download size (only with -S)
%l install date (only with -Q)
%m install size
%M modified backup files (only with -Q)
%n package name
%p packager name
%r repo
%s md5sum
%u project URL
%v version
%w install reason (only with -Q)
%! result number (auto-incremented counter, starts at 0)
%% literal %
Note that for any lowercase tokens aside from %m and %k, full printf support is
allowed, e.g. %-20n. This does not apply to any list based, date, or numerical
output.
Standard backslash escape sequences are supported, as per printf(1).
=head1 EXAMPLES
Emulate pacman's search function:
=over 4
$ expac -Ss '%r/%n %v\n %d' <search terms>
=back
List the oldest 10 installed packages (by build date):
=over 4
$ expac --timefmt=%s '%b\t%n' | sort -n | head -10
