Cosgrove

Cosgrove is a STEEM Centric Discord Bot Framework that allows you to write your own Discord bots that interact with the STEEM blockchain.

One example of a bot that uses this framework is @banjo on SteemSpeak.

• Engine support provided by the Cosgrove::Utils module.
• Bug fixes
• Gem updates.

• Registration
  • $register <account> [chain] - associate account with your Discord user (chain default steem)
• Verification
  • $verify <account> [chain] - check account association with Discord users (chain default steem)
• Up Voting
  • $upvote [url] - upvote from cosgrove; empty or ^ to upvote last steemit link
  • The ability for each discord channel to have its own upvote weight, as well as have a default. Upvote voting weight can be:
    • dynamic - uses the bot's current voting recharge percent as the upvote percent.
    • upvote_rules - uses channel specific rules.
    • 100.00 % - can be any valid voting percentage.
    • disable_comment_voting - only posts can get votes.
  • CommentJob for creating automated replies.
  • Callback on_success_upvote_job which can be used to, for example, reply to the post after being upvoted.
  • Market data now uses Bittrex instead of Poloniex.
  • operators to keep track of steem accounts that can do things like block upvotes (by blockchain mute).
  • Support for HiveSQL
  • Optimized interactive messages to update as data is acquired in realtime

$ gem install cosgrove

... or in your Gemfile

source 'https://rubygems.org'

gem 'cosgrove'

Add a config file to your ruby project called config.yml:

:cosgrove:
  :token: 
  :client_id: 
  :secure: set this
  :operators: <account names seperated by space>
  :upvote_weight: upvote_rules
  :upvote_rules:
    :channels:
      :default:
        :upvote_weight: 50.00 %
      :general_text:
        :channel_id: <Your Favorite Channel ID>
        :upvote_weight: 100.00 %
        :disable_comment_voting: true
:chain:
  :steem_account: 
  :steem_posting_wif: 
  :steem_api_url: https://api.steemit.com
  :steem_engine_api_url: https://api.steem-engine.com/rpc
  :hive_engine_api_url: https://api.hive-engine.com/rpc
  :hive_account: 
  :hive_posting_wif: 
  :hive_api_url: https://api.steem.house
:discord:
  :log_mode: info

You will need to request a token and client_id from Discord (see below).

Provide the accounts and wif private postings keys if you want your bot to upvote posts.

You should change the secure key using the output of:

SecureRandom.hex(32)

1. Request a new bot here: https://discordapp.com/developers/applications/me#top
2. Register an application and create an app bot user.
3. Replace APP_CLIENT_ID with the App's Client ID in this URL: https://discordapp.com/oauth2/authorize?&client_id=APP_CLIENT_ID&scope=bot&permissions=153600
4. Give that URL to the Discord server/guild owner and have them authorize the bot.
5. Set the token and client_id in your bot constructor (see below).

Some features provided by cosgrove require access to HiveSQL, which is a Microsoft SQL database containing all the Steem blockchain data.

Please note:

If you intend to use HiveSQL, you can provide the credentials in authorize-hive-sql.sh, then use this terminal command to enable HiveSQL just before running your bot. Copy the example example-authorize-hive-sql.sh and add your credentials:

source path/to/authorize-hive-sql.sh

Features that currently require HiveSQL:

• Details in $mvests command
• Any command that tries to suggest account names
• $upvote (when checking for dailly limits)

Cosgrove is based on discordrb, see: https://github.com/meew0/discordrb

All features offered by discordrb are available in Cosgrove. In addition, Cosgrove comes with pre-defined commands. See them by typing: $help

You can add you features thusly:

require 'cosgrove'

bot = Cosgrove::Bot.new

bot.message(with_text: 'Ping!') do |event|
  event.respond 'Pong!'
end

bot.run

Here's an example of a bot that does Engine API calls when you type: $bal ENG alice

require 'cosgrove'

include Cosgrove::Utils

bot = Cosgrove::Bot.new

bot.command :bal do |event, *args|
  symbol = args[0].strip.upcase
  account = args[0].strip.downcase
  params = {
    query: {
      symbol: symbol,
      account: account
    }
  }
  result = steem_engine_contracts(:findOne, params)
  
  "#{result['balance']}'s '#{result['symbol']}: #{result['balance']}"
end

bot.run

• Clone the client repository into a directory of your choice:
  • git clone git@github.com:steem-third-party/cosgrove.git
• Navigate into the new folder
  • cd cosgrove
• Basic tests can be invoked as follows:
  • rake
• To run tests with parallelization and local code coverage:
  • HELL_ENABLED=true rake
