The set of command-line tools and utility classes to simplify using Universa blockchain in ruby projects. Alfa stagem see usage section below for features by state.

Why not universa gem?

This workw was split from universa gem because of its lightweight nature allowing easy, painless upgrades, unlike huge universa gem that causes few megs of universa core libraries to be reinstalled on each release. Therefore, we limit releases of universa gem to the universa core and adapters updates, and put most of work in porgres in this lightweight gem.


Add this line to your application's Gemfile:

gem 'universa_tools'

And then execute:

$ bundle

Or install it yourself as:

$ gem install universa_tools


Please see online docs, the following are ready to beta test:

Command line tools:

When the gem is installed, get tools help with the terminal:

uctool -h    
uniring -h


After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

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 tags, and push the .gem file to rubygems.org.
