Rinku is a Ruby library that does autolinking.
It parses text and turns anything that remotely resembles a link into an HTML link,
just like the Ruby on Rails auto_link
method -- but it's about 20 times faster,
because it's written in C, and it's about 20 times smarter when linking,
because it does actual parsing instead of RegEx replacements.
Rinku is available as a Ruby gem:
$ [sudo] gem install rinku
The Rinku source is available at GitHub:
$ git clone git://github.com/tanoku/rinku.git
It exports a single method called Rinku.auto_link
.
require 'rinku'
auto_link(text, mode=:all, link_attr=nil)
auto_link(text, mode=:all, link_attr=nil) { |link_text| ... }
Parses a block of text looking for "safe" urls or email addresses, and turns them into HTML links with the given attributes.
NOTE: Currently the follow protocols are considered safe and are the only ones that will be autolinked.
http:// https:// ftp:// mailto://
Email addresses are also autolinked by default. URLs without a protocol
specifier but starting with www.
will also be autolinked, defaulting to
the http://
protocol.
-
text
is a string in plain text or HTML markup. If the string is formatted in HTML, Rinku is smart enough to skip the links that are already enclosed in tags. -
mode
is a symbol, either :all, :urls or :email_addresses, which specifies which kind of links will be auto-linked. -
link_attr
is a string containing the link attributes for each link that will be generated. These attributes are not sanitized and will be include as-is in each generated link, e.g.auto_link('http://www.pokemon.com', :all, 'target="_blank"') # => '<a href="http://www.pokemon.com" target="_blank">http://www.pokemon.com</a>'
This string can be autogenerated from a hash using the Rails
tag_options
helper. -
The method takes an optional block argument. If a block is passed, it will be yielded for each found link in the text, and its return value will be used instead of the name of the link. E.g.
auto_link('Check it out at http://www.pokemon.com') do |url| "THE POKEMAN WEBSITEZ" end # => 'Check it out at <a href="http://www.pokemon.com">THE POKEMAN WEBSITEZ</a>'
Auto-linking functionality has been removed from Rails 3.1,
and is instead offered as a standalone gem, rails_autolink
. You can
choose to use Rinku instead.
require 'rails_rinku'
The rails_rinku
package monkeypatches Rails with an auto_link
method that
mimics 100% the original one, parameter per parameter. It's just faster.

While Rinku is busy doing autolinks, you should be busy following me on twitter. @tanoku
. Do it.
