Tomlrb

A Racc based TOML Ruby parser supporting the 0.4.0 version of the spec.

TODO

• Better tests
• Dumper

Installation

Add this line to your application's Gemfile:

gem 'tomlrb'

And then execute:

$ bundle

Or install it yourself as:

$ gem install tomlrb

Usage

Tomlrb.parse("[toml]\na = [\"array\", 123]")

or

Tomlrb.load_file('my_file', symbolize_keys: true)

Benchmark

You can run the benchmark against the only other v0.4.0 compliant parser to my knowledge with ruby benchmarks/bench.rb.

Here are the results on my machine:

Calculating -------------------------------------
      emancu/toml-rb     1.000  i/100ms
     fbernier/tomlrb    46.000  i/100ms
-------------------------------------------------
      emancu/toml-rb     13.657  (± 7.3%) i/s -     69.000
     fbernier/tomlrb    486.095  (± 3.5%) i/s -      2.438k

Comparison:
     fbernier/tomlrb:      486.1 i/s
      emancu/toml-rb:       13.7 i/s - 35.59x slower

Development

After checking out the repo, run bin/setup to install dependencies. Then, run bin/console for an interactive prompt that will allow you to experiment.

Do not forget to regenerate the parser when you modify rules in the parser.y file using rake compile.

Run the tests using rake test.

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 to create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
