Unicode::Data

A Ruby wrapping for the unicode character data set.

Add this line to your application's Gemfile:

gem "unicode-data"

And then execute:

$ bundle

Or install it yourself as:

$ gem install unicode-data

When this gem is installed, it will automatically download the unicode character data set to a temporary zip file and generate a list of properties from that zip file. You can use this information (under lib/unicode/data/derived.txt) to implement, for example, a regular expression engine that can respect the unicode semantics defined by the unicode technical standard. At the moment the list of properties generated includes:

• General Categories
• Blocks
• Ages
• Scripts
• Script Extensions
• Core Properties (Math, Alphabetic, Lowercase, Case_Ignorable, etc.)
• Prop List Properties (White_Space, Bidi_Control, Terminal_Punctuation, etc.)

This lines up to almost all of the Onigmo unicode support (and a lot more), with the exception of:

• POSIX brackets
• Emoji

Use this like:

Unicode::Data.property?('\p{Math=True}', '<') # => true

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.
