ohai

Build status Gem Version

Description

Ohai detects data about your operating system. It can be used standalone, but its primary purpose is to provide node data to Chef.

Ohai will print out a JSON data blob for all the known data about your system. When used with Chef, that data is reported back via node attributes.

Chef distributes Ohai as a RubyGem. This README is for developers who want to modify the Ohai source code. For users who want to write plugins for Ohai, see the documentation:

Development Environment

Ohai's development dependencies should be installed with bundler. Just run bundle install in the root of the repo.

Spec Testing

We use RSpec for unit/spec tests. To run the full suite, run:

bundle exec rake spec

You can run individual test files by running the rspec executable:

bundle exec rspec spec/unit/FILE.rb

Style

We use Cookstyle, as a code linter, to enforce style guidelines. To run:

bundle exec rake style

You can run and automatically correct the issues:

bundle exec rake style:auto_correct

Rake Tasks

Ohai has some Rake tasks for doing various things.

bundle exec rake -T
rake build               # Build ohai-$VERSION.gem into the pkg directory
rake clean               # Remove any temporary products
rake clobber             # Remove any generated files
rake install             # Build and install ohai-$VERSION.gem into system gems
rake install:local       # Build and install ohai-$VERSION.gem into system gems without network access
rake release[remote]     # Create tag $VERSION and build and push ohai-$VERSION.gem to rubygems.org
rake spec                # Run RSpec code examples
rake style               # Run Chefstyle tests
rake style:auto_correct  # Auto-correct RuboCop offenses

($VERSION is the current version, from the GemSpec in Rakefile)
