Fedora modularization command line tool

This is repository for Fedora modularization command line tool ("fm").

It is standalone "fm" command which is used query fm-metadata-service API server to get metadata about available Fedora Modules.

In the future, this tool should be able to enable/disable modules and probably also install them. The long term goals now are not set to stone yet.

  • bin - Directory with then main "fm" script installed to /usr/bin.
  • docs - Documentation using the sphinx generator.
  • fm - Module with the core "fm" functionality.
  • plugins - DNF plugin implementing "dnf module" subcommand.
  • tests - Unit-tests based on nosetests framework.

You can install fm tool from source code using following commands:

Installation from RPM package

We also provide RPM package with the latest version of fm tool. Since we are in early stage in development, there is no stable fm release, so the packages are rebuilt from time to time when we will it's worth doing so.

[modules-repos]
name = Fedora modules repos
url = http://dev.fed-mod.org/modularity/repos

Now you can try listing all available modules in the testing repository as root:

# dnf module list
