DNF5
DNF5 is a command-line package manager that automates the process of installing, upgrading, configuring, and removing computer programs in a consistent manner. It supports RPM packages, modulemd modules, and comps groups and environments.
As part of the DNF5 stack, libdnf is the package management library. It was originally written to support the DNF package manager, but gradually grew up into a versatile library. You can now use libdnf to build custom tools that load repositories, query packages, resolve dependencies, and install packages.
DNF5 is also powered with the libsolv library which provides an easy to use programming interface.
By using DNF5, you can work with the following artifacts:
- RPM repositories (repomd)
- RPM packages
- Comps groups
- Comps environments
- Advisories (updateinfo, errata)
- Modules (modulemd)
DNF5 is written in C++ and it can interface with the following programming languages:
- C++ - fully supported.
- Python 3 - fully supported.
- Perl 5 - best effort.
- Ruby - best effort.
Note, however, that DNF5 cannot yet interface with the following programming languages:
- Go - does not work, we are looking for contributors.
- C - not implemented, not a priority for any of our existing API users.
