Ths calculates the Levenshtein distance between two strings, in Rust. It's 10x to 500x faster to standard Ruby implementations.
irb(main) LevenshteinRust.distance("Tim Brady", "Tim Brody")
=> "1"
Add this line to your application's Gemfile:
gem 'levenshtein_rust'And then execute:
$ bundle
Or install it yourself as:
$ gem install levenshtein_rust
This gem requires compiling if you develop and then use on a different OS, for instance develop on MacOs but use it on an Ubuntu server. The fool-proof way to compile is to
$ cd
$ git clone https://github.com/heri/levenshtein_rust.git
$ cd levenshtein_rust
Assuming you have rust installed :
$ rake build
This will create native.* files in lib/levenshtein_rust that work on your OS. Copy these native files to where the levenshtein_rust gem is installed. Example (customize depending on your local ruby/bundle install):
$ cp lib/levenshtein_rust/native.* /home/user/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/bundler/gems/levenshtein_rust
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.
