Google URL Shortener is a library to interact with the goo.gl URL shortener API. It provides:

• A CLI to easily shorten/expand URL’s
• A clean API to handle shortening/expanding URL’s in an application
• An interface to view analytical data for any short URL

The project is hosted on rubygems.org. Getting it is simple:

gem install google_url_shortener

You need to provide an API key (get one here) to use the URL shortener service. To do this set the api_key:

Google::UrlShortener::Base.api_key = "KEY"

You can also turn on verbose logging to inspect requests made by the library. Behind the scenes the library uses RestClient to call the API, therefore whatever you set here will be used as the RestClient log (RestClient.log).

Google::UrlShortener::Base.log = $stdout

To shorten a URL:

url = Google::UrlShortener::Url.new(:long_url => "http://blog.josh-nesbitt.net")
url.shorten! # => http://goo.gl/r5akx

Or the shorthand form:

Google::UrlShortener.shorten!("http://blog.josh-nesbitt.net") # => http://goo.gl/r5akx

To expand a URL:

url = Google::UrlShortener::Url.new(:short_url => "http://goo.gl/r5akx")
url.expand! # => http://blog.josh-nesbitt.net

Or the shorthand form:

Google::UrlShortener.expand!("http://goo.gl/r5akx") # => http://blog.josh-nesbitt.net

More data is available from a URL once it’s been expanded:

url = Google::UrlShortener::Url.new(:short_url => "http://goo.gl/r5akx")
url.expand! # => http://blog.josh-nesbitt.net
url.created_at # => 2011-01-11
url.created_at.year # => 2011
url.analytics # => Google::UrlShortener::Analytics
url.analytics.all # => Google::UrlShortener::AnalyticsGroup
url.analytics.all.browsers # => { "Chrome" => 1 }
url.analytics.all.countries # => { "GB" => 1 }
url.analytics.all.platforms # => { "Macintosh" => 1 }
url.analytics.all.referrers # => { "Unknown/empty" => 1 }
url.analytics.all.long_url_clicks # => 23
url.analytics.all.short_url_clicks # => 3

Available scopes are:

all
month
week
day
two_hours

E.g: url.analytics.month.

There is also a CLI wrapper for Google URL Shortener. Firstly, you need to tell the CLI your API key (get one here):

googl install AIzaSyByl4x5CMcnm2rNWafmaUz5sljmzMWIgZ0

This saves your API key in ~/.googl.

To shorten a URL:

googl shorten http://example.com
googl s http://example.com

To expand a URL:

googl expand http://goo.gl/1234
googl e http://goo.gl/1234

You can also get analytical data from a short URL using the -a or --analytics flag:

googl expand http://goo.gl/1234 -a

You can use the CLI alongside something like pbcopy to make shortening URL’s crazy fast:

googl shorten http://example.com | pbcopy

Also use a bash function to simplify it further:

shorten (){
	googl shorten $1 | pbcopy
	echo "$1 shortened and copied to clipboard"
}

Which can be used as:

shorten http://example.com

Run the specs with the following command:

bundle exec rspec --require ./spec/spec_helper.rb --format nested --color spec/lib/*.rb spec/lib/**/*.rb

If you have any problems with Google Url Shortener, please file an issue.

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don’t break it in a
  future version unintentionally.
• Commit, do not mess with rakefile, version, or history.
  (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
