Archangel

A Ruby client library and command-line interface for the Archangel DLT system.

Installation

Add this line to your application's Gemfile:

gem 'archangel'

And then execute:

$ bundle

Or install it yourself as:

$ gem install archangel

Usage

You can store and fetch data using the command-line client:

bundle exec archangel store {id} {payload}

bundle exec archangel fetch {id}

Currently this will store the payload string into Archangel (based on the ID and current time) using the dummy filesystem driver. A simple driver for Guardtime's Catena DB is also available. Future versions will support richer data and more backend drivers.

Commands:
  archangel store ID PAYLOAD  # stores PAYLOAD for ID at the current time
  archangel fetch ID          # retrieves the PAYLOAD previously stored with ID

Options:
  [--driver=DRIVER]      # Backend driver to use [file|guardtime]. Defaults to file
  [--username=USERNAME]  # Guardtime username
  [--password=PASSWORD]  # Guardtime password
  [--dir=DIR]            # File storage root directory

Development

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.
