NAME¶

AptPkg::Version - APT package versioning class

SYNOPSIS¶

use AptPkg::Version;

DESCRIPTION¶

The AptPkg::Version module provides an interface to APT's package version handling.

AptPkg::Version¶

The AptPkg::Version package implements the APT pkgVersioningSystem class. An instance of the AptPkg::Version class may be fetched using the "versioning" method from an AptPkg::System object. The following methods are implemented:

label

Return the description of the versioning system, for example:

 

    Standard .deb
    

 

for Debian systems.

compare(A, B)

Compare package version A with B, returning a negative value if A is an earlier version than B, zero if the same or a positive value if A is later.

rel_compare(A, B)

Compare distribution release numbers.

check_dep(PKG, OP, DEP)

Check that the package version PKG satisfies the relation OP to the dependency version DEP.

 

The relation OP is specified in the Debian syntax regardless of the versioning system:

 

    <<  strictly earlier
    <=  earlier or equal
    =   exactly equal
    >=  later or equal
    >>  strictly later
    

upstream(VER)

Return the upstream component of the given version string.
