Blog Feed

This tutorial shows you how to get blogs details from the specified author, limited to five results.

Full, runnable src of Blog Feed can be downloaded as part of: tutorials/ruby (or download just this tutorial: devportal-master-tutorials-ruby-01_blog_feed.zip).

Script

blog_feed.rb

The script parses the creation date, assuming Zulu timezone (AKA UTC).

The output will be the latest five posts/reblogs for the account specified. If the author is the same as the account specified, it is assumed to be a post by this account. Otherwise, it is assumed to be a reblog.

It also counts the words in the content body by splitting the text into an array of strings, delimited by whitespace.

Finally, it creates the canonical URL by combining parent_permlink, author, and permlink.

Final code:

require 'rubygems'
require 'bundler/setup'

Bundler.require

account_name = ARGV[0]
api = Radiator::Api.new
query = {tag: account_name, limit: 5}
created = nil

api.get_discussions_by_blog(query) do |posts|
  posts.each do |post|
    words = post.body.split(/\s/)
    author = post.author
    type = author == account_name ? 'Post' : 'Reblog'
    uri = []

    uri << post.parent_permlink
    uri << "@#{author}"
    uri << post.permlink

    if created != post.created
      puts created = Time.parse(post.created + 'Z')
    end

    puts "  #{type}: #{post.title}"
    puts "  By: #{author}"
    puts "  Words: #{words.size}"
    puts "  https://hive.blog/#{uri.join('/')}"
  end
end
