# Pascalina
## Usage
TODO: ...
### AST cache
Pascalina doesn't handle the AST cache like other alternatives, but you can
cache it your-self and pass it with `evaluate_ast`.
Check the `benchmark/ast.rb` to see the usage:
```ruby
Warming up --------------------------------------
evaluate 634.000 i/100ms
marshal evaluate_ast 1.464k i/100ms
direct evaluate_ast 1.595k i/100ms
Calculating -------------------------------------
evaluate 5.783k (±14.2%) i/s - 29.164k in 5.146870s
marshal evaluate_ast 14.502k (±18.1%) i/s - 70.272k in 5.015046s
direct evaluate_ast 22.910k (±19.1%) i/s - 106.865k in 5.046620s
Comparison:
direct evaluate_ast: 22910.4 i/s
marshal evaluate_ast: 14502.0 i/s - 1.58x (± 0.00) slower
evaluate: 5782.7 i/s - 3.96x (± 0.00) slower
```

## Installation
Add this line to your application's Gemfile:
```ruby
gem 'pascalina'
```
And then execute:
$ bundle install
Or install it yourself as:
$ gem install pascalina
## Development
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 the created tag, and push the `.gem` file to [rubygems.org](https://rubygems.org).
