RssWatcher

A Ruby Gem For Watching RSS Feeds

Installation

Add this line to your application's Gemfile:

gem 'rss_watcher'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rss_watcher

Usage Example

Whenever a new item is detected on the RSS feed, the given block is called with the item that was detected. item is an instance of a parsed RSS item using the Ruby RSS library. You should be able to access properties of the item using methods of the same name (e.g title, description, link, pubDate)

require "rss_watcher"
RssWatcher.watch(url: "http://lorem-rss.herokuapp.com/feed") do |item|
    puts item.title
    puts item.description
    puts item.link
end

Options

• url : URL of the RSS Feed to be watched (Required | String)
• update_interval: Time (in seconds) to wait between checking the url for updates (Optional | Default: 10 | Integer)
• cache_file: Path to a file that this gem uses internally for remembering the last seen item (Optional | Default: "rss_watcher.cache" | String)

RssWatcher.watch(url: "http://lorem-rss.herokuapp.com/feed", update_interval: 1, cache_file: "~/.tmp/rss_watcher_cache") do |item|
    puts item.pubDate
    puts item.link
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
