To begin implementing the functionality for a particular chapter:\n\n```\n$ bundle install\n$ git checkout chapter-two\n$ bundle exec rspec\n```\n\nThe examples expect to be able to instantiate a class called `LittleScheme::Parser` and call its `parse` method to get the abstract syntax tree (AST) of a program, and then to be able to instantiate a class called `LittleScheme::Evaluator` and call its `evaluate` method to evaluate that AST. If you run the examples, the failures should guide you.\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftomstuart%2Flittle_scheme","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftomstuart%2Flittle_scheme","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftomstuart%2Flittle_scheme/lists"}
