TODO: ...
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:
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

Add this line to your application's Gemfile:
gem 'pascalina'
And then execute:
$ bundle install
Or install it yourself as:
$ gem install pascalina
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.
