Gensym

Generate new, unbound variable names in your Ruby program. An homage to Lisp's gensym macro.

Handy for the kind of metaprogramming you really shouldn't be doing.

Usage

Instantiate a Gensym object by passing in a Binding. You'll probably want the binding of the current scope returned by Kernel#binding. Generate a new symbol by calling generate:

Gensym.new(binding).generate # => :gensym_OMUYsTEIbvjGwqhQgifkJNaByAHzxc

Installation

Add this line to your application's Gemfile:

gem "gensym"

And then execute:

$ bundle

Or install it yourself as:

$ gem install gensym

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec 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.
