OpenFact is a community implementation of Facter, a command-line tool that gathers basic facts about nodes (systems) such as hardware details, network settings, OS type and version, and more. These facts are made available as variables in your Puppet manifests and can be used to inform conditional expressions in Puppet.
Documentation for the Facter project can be found on the Puppet Docs site.
At the time of writing, the OpenVoxProject does not have a documentation website. But your help is very welcome! Reach out to the Documentation Special Interest Group if you want to help.

The project has three main parts, the framework, facts and resolvers. In the framework we implement functionality that is agnostic of specific facts like parsing user input, formatting output, etc.
Facts are the nuggets of information that will be provided by openfact e.g. os.name, networking.interfaces, etc.
Resolvers have the role of gathering data from the system. For example a resolver can execute a command on the system, can read a file or any operation that retrieves some data from a single source on the system.

After cloning the project, run bundle install to install all dependencies.
You can run openfact by executing ./bin/facter.
The command will output all the facts that openfact detected for the current OS.
The implementation can be validated locally by running bundle exec rake check.
