Flip the frozen bit on ruby objects, to unfreeze (thaw) them.
Note: You probably don't need to use this gem, you probably want to .dup your objects instead.
To-date, thaw works in Ruby 2.0 through 2.61.
Check the build status for the most current compatibility.
1There seems to be a segmentation fault in Ruby 2.7 that I haven't had time to investigate.
The best way to install is with RubyGems:
$ [sudo] gem install thaw
Or better still, just add it to your Gemfile:
gem 'thaw'
string = "hello"
string.frozen?
=> false
string.thawed?
=> true
string.freeze
string.frozen?
=> true
string.thawed?
=> false
string.thaw
string.frozen?
=> false
string.thawed?
=> true
After checking out the repo, run bundle to install dependencies. Then, run bundle exec rspec to run the tests.
