Natalie is a very early-stage work-in-progress Ruby implementation.
It provides an ahead-of-time compiler using C++ and gcc/clang as the backend. Also, the language has a REPL that performs incremental compilation.
There is much work left to do before this is useful. Please let me know if you want to help!
Contributions are welcome! You can learn more about how I work on Natalie via the hacking session videos on YouTube.
The easiest way to get started right now would be to find a method on an object that is not yet implemented and make it yourself!
Natalie is tested on macOS, OpenBSD, and Ubuntu Linux. Windows is not yet supported.
The compiler and REPL require MRI Ruby. I only test with Ruby 2.7.x currently.
Install the above prerequisites on your platform, then run:
git clone https://github.com/seven1m/natalie cd natalie git submodule update --init gem install bundler bundle install make # or gmake if your system make isn't GNU make
NOTE: Currently, the default build is the "debug" build.
Run a Ruby script:
Compile a file to an executable:
bin/natalie examples/hello.rb -c hello ./hello
docker build -t natalie . # build image docker run -it --rm natalie # repl docker run -it --rm natalie -e "p 2 * 3" # immediate docker run -it --rm -v$(pwd)/myfile.rb:/myfile.rb natalie /myfile.rb # execute a local nat file docker run -it --rm --entrypoint bash natalie # bash prompt
