== LibIDN Ruby Bindings Version 0.1.0 Ruby Bindings for the GNU LibIDN library, an implementation of the Stringprep, Punycode and IDNA specifications defined by the IETF Internationalized Domain Names (IDN) working group. Included are the most important parts of the Stringprep, Punycode and IDNA APIs like performing Stringprep processings, encoding to and decoding from Punycode strings and converting entire domain names to and from the ACE encoded form. The latest version of the LibIDN Ruby Bindings project and its documentation can always be found at * https://github.com/deepfryed/idn-ruby The original version can be found at, * http://rubyforge.org/projects/idn See the CHANGES file for detailed information on the changes of every released version. === Requirements * GNU LibIDN[http://www.gnu.org/software/libidn/] Library * Rake[http://rubyforge.org/projects/rake] to run the tests and generate the documentation * RubyGems[http://docs.rubygems.org/] to produce a Gem package * Ruby 1.9.1 or above. Patches welcome to make this work in 1.8.7 === Installation You can easily install the LibIDN Ruby Bindings by following one of the ways outlined below: ==== Automatic installation and management with RubyGems Simply invoke the standard RubyGems commands (install, update, ...), for example: % gem install --remote --test idn or if the GNU LibIDN library can only be found in a non-standard location % gem install --remote --test idn -- \ --with-idn-dir=/path/to/non/standard/location or in an even more complex setup % gem install --remote --test idn -- \ --with-idn-lib=/path/to/non/standard/location/lib \ --with-idn-include=/path/to/non/standard/location/include ==== Semi-automatic installation with Rake If you are not able to or don't want to use RubyGems you can simply download the latest release and install it with the help of Rake: % tar -xvzf idn-x.x.x.tar.gz % cd idn-x.x.x % rake install or if the GNU LibIDN library can only be found in a non-standard location % rake install IDN_DIR=/path/to/non/standard/location You can also run the tests or generate the documentation; just call Rake with the '--tasks' parameter to get an overview of the available tasks: % rake --tasks ==== Manual installation with extconf.rb If you are not able to or don't want to use even Rake then you will have to do a little bit more work by yourself: % tar -xvzf idn-x.x.x.tar.gz % cd idn-x.x.x/ext % ruby extconf.rb or if the GNU LibIDN library can only be found in a non-standard location % ruby extconf.rb \ --with-idn-dir=/path/to/non/standard/location or in an even more complex setup % ruby extconf.rb \ --with-idn-lib=/path/to/non/standard/location/lib \ --with-idn-include=/path/to/non/standard/location/include and finally % make % sudo make install === Documentation The complete documentation is available online at * http://rubydoc.info/github/deepfryed/idn-ruby/master/frames ==== Example usage require 'idn' include IDN puts 'Idna.toUnicode: ' + Idna.toUnicode('xn--rksmrgs-5wao1o.josefsson.org') puts 'Punycode.decode: ' + Punycode.decode('egbpdaj6bu4bxfgehfvwxn') puts 'Stringprep.with_profile: ' + Stringprep.with_profile('FOO', 'Nameprep') === References [GNU LibIDN] An implementation of the Stringprep, Punycode and IDNA specifications defined by the IETF Internationalized Domain Names (IDN) working group, used for internationalized domain names.
