SYNOPSIS
use RPM::VersionCompare;
RPM::VersionCompare::rpmvercmp('1.0', '0.9');
RPM::VersionCompare::labelSplit('4:5.12.0-140');
RPM::VersionCompare::labelCompare('4:5.12.0-140', '5.14.1');
DESCRIPTION
This module provides functions to compare RPM version strings. No
function is exported by default. If possible, calls are passed to
native librpm library. Otherwise Python extension provided with RPM
sources is re-implemented.
labelCompare(LABEL1, LABEL2)
Compares two version strings including epoch and release.
Return 1 if LABEL1 is bigger, return 0 if LABEL1 equals to
LABEL2, return -1 otherwise.
labelSplit(LABEL)
Splits a version LABEL (e.g. "4:5.12.0-140") into epoch,
version and release. The epoch and release parts are optional.
If they miss, the separator (collon for epoch, hyphen for
release) should miss too and their implicit value is 0. See
<http://www.rpm.org/wiki/PackagerDocs/Dependencies#RequiringPackages>
for specification.
If LABEL is in correct format, array (EPOCH, VERSION, RELEASE)
will be returned. Otherwise undef is returned.
rpmvercmp(VERSION1, VERSION2)
Compares two RPM version strings by calling librpm function
rpmvercmp(). It does not support strings with RPM epoch or
release. (Use labelCompare() if you need to support epoch or
release.) It will return 1 if VERSION1 string is bigger, 0 if
strings are equal, and -1 if VERSION1 is lesser.
