rpms – RPM metadata

This module provides classes for manipulating rpms.json files. rpms.json files provide details about RPMs included in composes.

Example:

import productmd.compose
compose = productmd.compose.Compose("/path/to/compose")

# Print the entire dict that maps all variants, arches, and RPMs for this
# compose:
print(compose.rpms.rpms)

# Find all the source RPMs in this compose:
srpms = set()

for variant in compose.rpms.rpms:
    for arch in compose.rpms.rpms[variant]:
        for srpm in compose.rpms.rpms[variant][arch]:
            srpms.add(srpm)

print(srpms)
# ... prints the set of SRPMs in all our variants:
# ['ceph-2:12.2.5-25.el7cp.src',
#  'ceph-ansible-0:3.1.0-0.1.rc9.el7cp.src',
#  'ceph-iscsi-cli-0:2.7-1.el7cp.src',
#  ...
# ]
