Horologium

Horologium is a Ruby library dedicated to scientific time: the time scales (UTC, TAI, TT, TDB, TCG, TCB, UT1, GPS), high-precision instants, Julian Dates, intervals, and rigorous conversions between scales that astronomy and physics require.

Install the gem and add it to the application's Gemfile by running:

bundle add horologium

Or install it directly:

gem install horologium

After checking out the repo, run bin/setup to install dependencies. Then, run rake to run the tests and RuboCop, or rake steep to type-check the signatures in sig/. Run COVERAGE=true rake test to measure test coverage, which is enforced at a 95% line minimum in CI. You can also run bin/console for an interactive prompt that will allow you to experiment.

Run bin/ci to run every check that GitHub Actions runs (RuboCop, Steep, YARD documentation coverage, and the tests with coverage) in a single pass. It runs each check even when an earlier one fails, so you see everything that needs fixing at once.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.

Bug reports and pull requests are welcome on GitHub at https://github.com/rhannequin/horologium.
