Archive::RPM(3) User Contributed Perl Documentation Archive::RPM(3)NAMEArchive::RPM - Work with a RPM
SYNOPSIS
use Archive::RPM;
my $rpm = Archive::RPM->new('foo-1.2-1.noarch.rpm');
# RPM2 header functions...
# other functions...
DESCRIPTIONArchive::RPM provides a more complete method of accessing an RPM's
meta- and actual data. We access this information by leveraging RPM2
where we can, and by "exploding" the rpm (with rpm2cpio and cpio) when
we need information we can't get through RPM2.
TRAITS
This package allows for the application of various "TraitFor" style
traits through the with_traits() function, e.g.:
Archive::RPM->with_traits('Foo')->new(...);
By default, we look for traits in the "Archive::RPM::TraitsFor"
namespace, though this can be overridden by prepending a "+" to the
full package name of the trait.
METHODS
An object of this class represents an actual RPM, somewhere on the
filesystem. We provide all the methods RPM2::Header does, as well as
additional functions to manipulate/extract the rpm itself (but not to
install).
Right now, our documentation is horrible. Please see RPM2 for the
methods provided by "RPM2::Header", and the source for the other
functions we have defined. We support all methods provided by
RPM2::Header, except the "files" method (that's handled by other bits).
new('file.rpm') | new(rpm => 'file.rpm', ...)
Creates a new Archive::RPM object. Note that the rpm parameter is
required, and if it is the only one being passed the "rpm =>" may
be omitted.
rpm => 'filename'|Path::Class::File
Required. Takes either a filename or a Path::Class::File
object pointing to the rpm.
auto_cleanup => 0|1
Default is 1; if the rpm is extracted to the filesystem, purge
this automatically.
rpm Returns a Path::Class::File object representing the rpm we're
working with.
extracted_to
Returns a Path::Class::Dir object representing where the rpm has
been exploded to. If the rpm has not been exploded, it will be.
has_been_extracted
Returns true if the rpm has been exploded; false if not.
is_source_package | is_srpm | is_source
Returns true if this is a source rpm; false if not.
has_files
True if this rpm contains any files. (Some, e.g. Fedora's "perl-
core" package, are "meta-packages" and do not deliver files; they
simply ensure a given set of dependencies exist on a system. Sort
of like Task::* CPAN dists.)
num_files
Returns the number of files delivered.
grep_files
Grep over the array of files; e.g.
my ($spec) = $srpm->grep_files(sub { /\.spec$/ });
map_files
files
Returns an array of all the dir/files delievered by the rpm. Note
that these are returned as Path::Class objects, and we use the
directories and files present on the filesystem after exploding the
rpm rather than the list described by the rpm itself.
first_file
last_file
join_files
num_changelog_entries
Returns the total number of changelog entries.
changelog_entries
Returns an array of all the changelog entries.
first_changelog_entry
Returns the first changelog entry; note that changelogs are stored
in reverse chronological order. That is, the first changelog entry
is the newest entry.
last_changelog_entry
Returns the oldest changelog entry.
get_changelog_entry(Int)
Get a specific changelog entry.
map_changelog_entries
find_changelog_entry
grep_changelog_entries
DIAGNOSTICS
We tend to complain and die loudly on any errors.
SEE ALSO
RPM2
LIMITATIONS
Our documentation and test suite is clearly lacking, sadly.
We also have to explode the rpm for anything more intense than simply
looking at the header for info. While this isn't really a _horrible_
thing, it's annoying to have to, say, explode a 100MB ooffice rpm just
to get a count of how many files there are in it.
We do the "exploding" using external rpm2cpio and cpio binaries. While
we could have used Archive::Cpio to handle the cpio extraction, it
seemed a touch overkill; as there does not appear to be a Perl library
to handle the "rpm2cpio" part, we may as well use the cpio bin. (It's
not like it's missing from many systems, anyways.
BUGS
All complex software has bugs lurking in it, and this module is no
exception. If you find a bug please either email me, or (preferred) to
this package's RT tracker at "bug-Archive-RPM@rt.cpan.org".
Patches are welcome.
