fedrq¶
A tool for querying the Fedora and EPEL repositories
fedrq makes it easy to query any branch of Fedora or EPEL. It uses the dnf
Python bindings and does not shell out to dnf repoquery. It allows querying
for reverse dependencies, packages that contain a certain Provide or file,
subpackages of an SRPM, and package metadata.
The tool doesn’t seek to replace every feature of dnf repoquery. It provides a
more user friendly interface than dnf repoquery for certain common tasks.

Installation¶
fedrq has a Copr repository at gotmax23/fedrq that contains released versions. Development snapshots are available at gotmax23/fedrq-dev. The RPM specfile is located in the repository root.
fedrq is also published to PyPI so you can
pip install fedrq.
When installing the package with pip, some additional system packages are needed.
The following additional system package is required for the dnf backend:
- python3-dnf (dnf is currently the default Fedora package manager, so this should already be installed)
The following additional system packages are required for the libdnf5 backend:
- python3-libdnf5
The following additional system packages are always required:
- python3-rpm
fedrq defaults to the dnf backend, but fedrq falls back to the libdnf5 backend
if the former’s dependencies aren’t installed.
Users can explicitly choose a backend with the
--backend CLI option
or globally in the fedrq config file.
Note that fedrq can only be installed for the system python interpreter.
fedrq cannot be installed in a venv unless it has --system-site-packages,
as it needs to find the aforementioned system bindings.
fedrq check-config --dump requires tomli-w.
The RPM package weakly depends on python3-tomli-w.
Container images¶
fedrq now provides container images.
quay.io/gotmax23/fedrq:latestis built withregistry.fedoraproject.org/fedora:latest.quay.io/gotmax23/fedrq:ubi9is built with the ubi9 image. It includes a builtinrhel9repository configuration that can be used to query the actual RHEL repositories when run on a system registered with subscription-manager.
Both of these images use the latest fedrq RPM packages from the gotmax23/fedrq Copr repository.

Versioning¶
This project is in beta and its versioning scheme follows semver.
See NEWS.md.
Python API¶
The fedrq.config module and the fedrq.backend package are public API.
Everything under fedrq.cli is internal. fedrq is primarily a CLI tool and
its API only abstracts the specific dnf/libdnf5 functionality that the CLI uses. The
API’s main purpose is “repoquerying”, but you can use the fedrq functionality
you’d like and then access the underlying dnf Base object to preform other
tasks if needed.
See the API Summary on the docsite for more information. See api-examples for some example code. As always, direct any feedback, questions, or issues to the mailing list (see Contributing).
Documentation¶
See fedrq’s documentation site for rendered manpages, changelogs, and Python API documentation.
Contributing¶
Development, issue reporting, and project discussion happen on the mailing list (~gotmax23/fedrq@lists.sr.ht).
See CONTRIBUTING.md.
