Radiator v0.1.0 - Golos Ruby API Client

radiator

STEEM Ruby API Client

Radiator is an API Client for interaction with the STEEM network using Ruby.

Fixes in v0.1.0

Improved reliability of Stream.
Handling more broadcast datatypes.

Quick Start

Add the gem to your Gemfile:

gem 'radiator', github: 'inertia186/radiator'

Then:

$ bundle install

If you don't have bundler, see the next section.

Prerequisites

Linux

$ sudo apt-get install ruby-full git openssl libssl1.0.0 libssl-dev
$ gem install bundler

macOS

$ gem install bundler

Usage

require 'radiator'

api = Radiator::Api.new
response = api.get_dynamic_global_properties
response.result.virtual_supply
=> "135377049.603 STEEM"

Follower API

api = Radiator::FollowApi.new
response = api.get_followers('inertia', 0, 'blog', 100)
response.result.map(&:follower)
=> ["a11at",
 "abarefootpoet",
 "abit",
 "alexgr",
 "alexoz",
 "andressilvera",
 "applecrisp",
 "arrowj",
 "artificial",
 "ash",
 "ausbitbank",
 "beachbum",
 "ben99",
 "benadapt",
 .
 .
 .
 "steemzine"]

Here's an example of how to use a streaming instance to listen for votes:

require 'radiator'

stream = Radiator::Stream.new

stream.operations(:vote) do |op|
  print "#{op.voter} voted for #{op.author}"
  puts " (weight: #{op.weight / 100.0}%)"
end

The output would look like this and continue until interrupted.

richman voted for krnel (weight: 100.0%)
rainchen voted for rainchen (weight: 100.0%)
richman voted for exploretraveler (weight: 100.0%)
jlufer voted for michaelstobiersk (weight: 100.0%)
jlufer voted for michaelstobiersk (weight: 100.0%)
patelincho voted for borishaifa (weight: 100.0%)
richman voted for vetvso (weight: 100.0%)
jlufer voted for michaelstobiersk (weight: 100.0%)
richman voted for orcish (weight: 100.0%)
demotruk voted for skeptic (weight: -100.0%)
photorealistic voted for oecp85 (weight: 100.0%)
meesterboom voted for rubenalexander (weight: 100.0%)
thecurator voted for robyneggs (weight: 40.0%)
richman voted for originate (weight: 100.0%)
helikopterben voted for etcmike (weight: 100.0%)
.
.
.

Streaming

You can also just stream all operations like this:

stream.operations do |op|
  puts op.to_json
end

Example of the output:

{
   "vote":{
      "voter":"abudar",
      "author":"rangkangandroid",
      "permlink":"the-kalinga-tattoo-maker",
      "weight":10000
   }
}
{
   "vote":{
      "voter":"shenburen",
      "author":"masteryoda",
      "permlink":"daily-payouts-leaderboards-september-16",
      "weight":10000
   }
}
{
   "vote":{
      "voter":"stiletto",
      "author":"fyrstikken",
      "permlink":"everybody-hating-me",
      "weight":2500
   }
}
{
   "comment":{
      "parent_author":"mariandavp",
      "parent_permlink":"re-onceuponatime-re-mariandavp-the-bridge-original-artwork-by-mariandavp-20160906t182016608z",
      "author":"onceuponatime",
      "permlink":"re-mariandavp-re-onceuponatime-re-mariandavp-the-bridge-original-artwork-by-mariandavp-20160917t054726763z",
      "title":"",
      "body":"https://www.steemimg.com/images/2016/09/17/oldcomputerpics551cb14c.jpg",
      "json_metadata":"{\"tags\":[\"art\"],\"image\":[\"https://www.steemimg.com/images/2016/09/17/oldcomputerpics551cb14c.jpg\"]}"
   }
}
{
   "vote":{
      "voter":"abudar",
      "author":"rangkangandroid",
      "permlink":"the-journey-north-through-the-eyes-of-kalinga-tradition",
      "weight":10000
   }
}
{
   "limit_order_cancel":{
      "owner":"fnait",
      "orderid":2755220300
   }
}
.
.
.

Transactions are supported:

stream.transactions do |tx|
  puts tx.to_json
end

Example of the output:

{
   "ref_block_num":59860,
   "ref_block_prefix":2619183808,
   "expiration":"2016-09-17T06:03:21",
   "operations":[
      [
         "custom_json",
         {
            "required_auths":[

            ],
            "required_posting_auths":[
               "acidpanda"
            ],
            "id":"follow",
            "json":"[\"follow\",{\"follower\":\"acidpanda\",\"following\":\"gavvet\",\"what\":[\"blog\"]}]"
         }
      ]
   ],
   "extensions":[],
   "signatures":[
      "2048d7e32cc843adea0e11aa617dc9cdc773d0e9a0a0d0cd58d67a9fcd8fa2d2305d1bb611ac219fbd3b6a77ab60071df94fe193aae33591ee669cc7404d4e4ec4"
   ]
}
.
.
.

Even whole blocks:

stream.blocks do |bk|
  puts bk.to_json
end

Example of the output:

{
   "previous":"004cea0d46a4b91cffe7bb71763ad2ab854c6efd",
   "timestamp":"2016-09-17T06:05:51",
   "witness":"boatymcboatface",
   "transaction_merkle_root":"0000000000000000000000000000000000000000",
   "extensions":[],
   "witness_signature":"2034b0d7398ed1c0d7511ac76c6dedaf227e609dc2676d13f926ddd1e9df7fa9cb254af122a4a82dc619a1091c87293cbd9e2db1b51404fdc8fb62f8e5f37b4625",
   "transactions":[]
}
.

Transaction Signing

Radiator supports transaction signing, so you can use it to vote:

tx = Radiator::Transaction.new(wif: 'Your Wif Here')
vote = {
  type: :vote,
  voter: 'xeroc',
  author: 'xeroc',
  permlink: 'piston',
  weight: 10000
}

op = Radiator::Operation.new(vote)
tx.operations << op
tx.process(true)

You can also post/comment:

tx = Radiator::Transaction.new(wif: 'Your Wif Here')
comment = {
  type: :comment,
  parent_permlink: 'test',
  author: 'your-account',
  permlink: 'something-unique',
  title: 'Radiator Can Post Comments!',
  body: 'Yep, this post was created by Radiator in `ruby`.',
  json_metadata: '',
  parent_author: ''
}

op = Radiator::Operation.new(comment)
tx.operations << op
tx.process(true)

Transfers:

tx = Radiator::Transaction.new(wif: 'Your Wif Here')
transfer = {
  type: :transfer,
  from: 'ned',
  to: 'inertia',
  amount: '100000.000 SBD',
  memo: 'Wow, inertia!  Radiator is great!'
}

op = Radiator::Operation.new(comment)
tx.operations << op
tx.process(true)

Golos

Radiator also supports Golos. To use the Golos blockchain, provide a node and chain_id:

tx = Radiator::Transaction.new(wif: 'Your Wif Here', chain: :golos, url: 'https://node.golos.ws')
vote = {
  type: :vote,
  voter: 'xeroc',
  author: 'xeroc',
  permlink: 'piston',
  weight: 10000
}

op = Radiator::Operation.new(vote)
tx.operations << op
tx.process(true)

There's a complete list of operations known to Radiator in broadcast_operations.json.

- git clone https://github.com/inertia186/radiator.git
Navigate into the new folder
