Using Web Feeds to Build Planet Sites in Ruby

A web feed (or news feed) is a simple document/data format that 1) lets you publish a list of status updates, blog postings, articles, pictures, cartoons, recordings, etc and that 2) lets others subscribe to your updates.

viennarb.ini

title  = Planet Vienna.rb

[viennarb]
  title   = Vienna.rb Blog
  link    = http://vienna-rb.at
  feed    = http://vienna-rb.at/atom.xml

[viennarbmeetup]
  title = Vienna.rb Meetups
  link  = http://www.meetup.com/vienna-rb
  feed  = http://www.meetup.com/vienna-rb/events/rss/vienna.rb/

$ pluto build viennarb.ini

Github Actions

I set up a github action using the ruby template, to update the feeds of identosphere.net every 3 hours:

didecentral/planetid-reboot/.github/workflows/ruby.yml

# This workflow will download a prebuilt Ruby version, install dependencies and run tests with Rake
# For more information see: https://github.com/marketplace/actions/setup-ruby-jruby-and-truffleruby

name: Ruby

on:
  schedule:
    # * is a special character in YAML so you have to quote this string
    - cron:  '15 * * * *'

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v2
    - name: Set up Ruby
    # To automatically get bug fixes and new Ruby versions for ruby/setup-ruby,
    # change this to (see https://github.com/ruby/setup-ruby#versioning):
    # uses: ruby/setup-ruby@v1
      uses: ruby/setup-ruby@ec106b438a1ff6ff109590de34ddc62c540232e0
      with:
        ruby-version: 2.6
    - name: Install dependencies
      run: sudo apt-get install libsqlite3-dev && gem install pluto
    - name: build reader
      run: pluto b planetid.ini -t planetid -o docs
    - name: Deploy Files
      run: |
        git remote add gh-token "https://github.com/didecentral/planetid-reboot.git"
        git config user.name "github-actions[bot]" # I use the GitHub Actions bot here.
        git config user.email "41898282+github-actions[bot]@users.noreply.github.com"
        git commit -a -m "update feeds"
        git push gh-token master

Planet Feed Reader in 20 Lines of Ruby

planet.rb:

require 'open-uri'
require 'feedparser'
require 'erb'

# step 1) read a list of web feeds

FEED_URLS = [
  'http://vienna-rb.at/atom.xml',
  'http://weblog.rubyonrails.org/feed/atom.xml',
  'http://www.ruby-lang.org/en/feeds/news.rss'
]

items = []

FEED_URLS.each do |url|
  feed = FeedParser::Parser.parse( open( url ).read )
  items += feed.items
end

# step 2) mix up all postings in a new page

FEED_ITEM_TEMPLATE = <<EOS
<%% items.each do |item| %>
  <div class="item">
    <h2><a href="<%%= item.url %>"><%%= item.title %></a></h2>
    <div><%%= item.content %></div>

EOS

puts ERB.new( FEED_ITEM_TEMPLATE ).result
