String#camelize Ruby Extension

fast_camelize is a C extension that provides a fast implementation of ActiveSupport's String#camelize method.

At last check, these were the benchmarks (obtained by running bin/bench with ActiveSupport 6.1.3):

Warming up --------------------------------------
       ActiveSupport    20.000  i/100ms
        FastCamelize    74.000  i/100ms
Calculating -------------------------------------
       ActiveSupport    202.091  (± 7.4%) i/s -      1.020k in   5.081583s
        FastCamelize    974.025  (± 2.3%) i/s -      4.884k in   5.016944s

Comparison:
        FastCamelize:      974.0 i/s
       ActiveSupport:      202.1 i/s - 4.82x  (± 0.00) slower

Add this line to your application's Gemfile:

gem "fast_camelize"

And then execute:

$ bundle

Or install it yourself as:

$ gem install fast_camelize

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.
