NAME

RPM::Search - Search all available RPMs

SYNOPSIS

# On (recent) RPM based systems
my $db = RPM::Search->new();

my @names = $db->search(qr/perl-Mo.se/);
# or
@names = $db->search('perl-CGI-*');
# or
@names = $db->search('cpanminus');

if ( @names ) {
  my $pkgs = join ", ", @names;
  `/usr/bin/yum -y install $pkgs`;
}
else {
    print "No matching packages\n";
}

PURPOSE

This module allows one to search the entire collection of RPMs available for a given installed Linux distribution that uses RPMs, not just listing the RPMs already installed on a system.

And frankly, have you tried using yum search?

Eventually, I plan to use this functionality to make a plugin for cpanminus to suggest vendor-supplied packages instead of building them "from scratch."

ATTRIBUTES

These are standard Perlish accessors: pass an argument to set it, pass no argument to get the current value.

cache_base

Base location of the yum data (default: none)

yum_primary_db

Fully qualified path to the primary SQLite database (default: none)

dbh

DBI handle to the yum SQLite database

METHODS

new()

Make a new RPM::Search object. Will automatically search for an appropriate yum database and open a handle to the data set unless you pass valid arguments to the dbh and/or yum_primary_db attributes at construction time.

Returns a new RPM::Search object.

find_yum_db()

This method searches for an appropriate yum database starting at the location passed as a parameter. If no parameter is given, the method will use cache_base. If cache_base is not set, the method will use /var/cache/yum.

This call populates yum_primary_db.

The return value is boolean: true for success, false for failure.

open_db()

This method opens a connection to the yum SQLite database. The DSN is constructed from the passed in parameter. If no parameter is passed in, the method will use yum_primary_db.

This method populates dbh.

This method causes a fatal error on any failure.

search()

This method searches the RPM database using an optional pattern parameter. If no pattern is given, the method returns all available package names. (Note: This will be thousands of packages.)

The format of the pattern can be one of the following:

  • A regular expression using the qr// construct.

  • A SQL-ish wildcard expression using % and _

  • A filesystem like glob expression using ? and *

  • A scalar which must be a literal match for a package name in the database to return any results

The method returns an array of all matching package names (which may be zero results.) Undef is returned on errors.
