Lisk.rb¶ ↑

A simple Ruby wrapper for the Lisk API. 💎

Note before using¶ ↑

This is very early work-in-progress. The idea is to publish this gem as soon as it is fully compatible with Lisk Core 1.0.0, which, however, is not released yet. The current implementation of the lisk.rb gem is pure minimal by design and barely allows checking the node status.

API Implemententation Status:

• Lisk::Legacy 48/62 APIs for Lisk Core 0.8.0+ (#4)

• Lisk::Raw 0/34 APIs for Lisk Core 1.0.0+ (#1)

Installation¶ ↑

Add this line to your application's Gemfile:

gem 'lisk'

And then execute:

$ bundle

Or install it yourself as:

$ gem install lisk

Usage¶ ↑

Make sure to include lisk.rb in your scripts.

require 'lisk'

To get started, point the lisk.rb to any Lisk-API endpoint. By default, lisk.rb assumes a running Lisk testnet node on localhost port 7000.

node = Lisk::Client.new "127.0.0.1", 7000

For convenience, check if the Lisk node is connected, fully synchronized, and active by pinging it.

if node.is_alive?
  # only do stuff if client is connected, fully synchronized, and active ...
end

Get access to the Lisk-0.8.0 legacy API (see #4).

lisk = Lisk::API.new node

Get the version of the connected Lisk node.

version = lisk.get_version
build = lisk.get_version_build
p "Lisk node version #{version} build #{build}..."

Get the status of the connected Lisk node.

connected = node.is_alive?
loaded = lisk.is_chain_loaded?
p "Lisk node is connected: #{connected}... Blockchain loaded: #{loaded}..."

Figure out if the node is still synchronizing.

syncing = lisk.is_syncing?
remaining = lisk.get_remaining_blocks
best = lisk.get_chain_best_block
p "Lisk node is syncing: #{syncing}... #{remaining} remaining blocks to latest block #{best}..."

Get some global Lisk blockchain stats.

height = lisk.get_best_block
reward = lisk.get_block_reward / 1e8
supply = lisk.get_available_supply / 1e8
p "Lisk chain latest block: #{height}... total supply: #{supply}... block reward: #{reward}"

See examples/*.rb for more examples implementing the Lisk API.

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.
