A Ruby language with Lisp syntax.

The compilation process:

1. Read the Lisp source code from a file.
2. Parse the source into an abstract syntax tree made up of Ruby objects.
3. Transform and optimise the AST if need be.
4. Convert the AST into strings of Ruby code.
5. Write the strings to files.

To compile an emerald file e.g example.emerald , run:

ruby emerald.rb example.emerald

The evaluated code will be output to the console, and the generated Ruby code will be can be found in compiled_lisp.rb

To run all tests, run:

rspec spec

To run linting with Rubocop, run:

bundle exec rubocop
