• Title: drdoogie.rb - Vote Trail Bot for Hive
• Tags: radiator ruby curation
• Notes:

Fixes

Added support for Hive.

Features

• YAML config.
  • global
    • mode
      • head - the last block
      • irreversible - (default) the block that is confirmed by 2/3 of all block producers and is thus irreversible!
  • scale_votes - scale votes in %
  • max_age - only vote if the post is under this number in minutes
  • allow_upvote - trail upvotes
  • allow_downvote - trail downvotes
  • enable_comments - vote for comments
  • skip_tags - do not vote if the post contains any of these tags
  • only_tags - only vote if the post includes at least one of these tags

Overview

Dr. Doogie (drdoogie.rb) is a voting bot that will trail the votes of other accounts in order to then mirror their voting pattern.

Install

To use this Radiator script:

Get rvm

See: rvm.io

Get bundler

$ gem install bundler

Bundle

First, clone this gist and install the dependencies:

$ git clone https://gist.github.com/d57c9bc744f05ada01d173521c01df8a.git drdoogie
$ cd drdoogie
$ bundle install

Run

$ ruby drdoogie.rb

Check here to see an updated version of this script:

https://gist.github.com/inertia186/d57c9bc744f05ada01d173521c01df8a

---

Upgrade

Typically, you can upgrade to the latest version by this command, from the original directory you cloned into:

$ git pull

Usually, this works fine as long as you haven't modified anything. If you get an error, try this:

$ git stash --all
$ git pull --rebase
$ git stash pop

If you're still having problems, I suggest starting a new clone.

---

Troubleshooting

Problem: What does this error mean?

drdoogie.yml:1: syntax error, unexpected ':', expecting end-of-input

Solution: You ran ruby drdoogie.yml but you should run ruby drdoogie.rb.

---

Problem: Everything looks ok, but every time drdoogie tries to post, I get this error:

`from_base58': Invalid version (RuntimeError)

Solution: You're trying to vote with an invalid key.

Make sure the .yml file voters item have the correct account name and WIF posting key.

Problem: The node I'm using is down.

Is there a list of nodes?

Solution: Yes:
