dart_scheme_impl (skeleton)

This is skeleton code that, when complete, will allow you to build the online 61A Scheme interpreter.

Note: 61A Staff members don't need to use this repo. We have a private staff implementation of it in the dart_scheme_impl repo on our GitHub org.

See the setup instructions in the [dart_scheme][] contributing guide.

mkdir scheme && cd scheme
git clone git@github.com:Cal-CS-61A-Staff/dart_scheme.git
git clone git@github.com:jathak/scheme_impl_skeleton.git dart_scheme_impl

Implementing

You'll need to implement the various commented TODOs in lib/impl.dart. I've included the UnimplementedAsync mixin by default, since define-async and lambda-async are not commonly used. If you want them (effectively, async/await in Scheme), see the methods of ProjectInterface in the main repo.

The Scheme project spec from last semester may be helpful.

While I'm licensing this under the BSD 3-clause license to maintain consistency with the rest of the project, I ask that you please do not publicly distribute the source code that you implement here (dart2js builds are fine). We reuse the project that this code is based on each semester and would prefer that we did not have solutions floating around.

Additionally, if you are a Berkeley student, publicly distributing an implementation of ProjectInterface constitutes academic dishonesty as described in our course policies, as the implementation is close enough to the Scheme project's to be considered distribution of solutions, despite the change of language from Python to Dart. This applies even if you are not currently taking 61A.

An Alternate Option

You can contact me either by email or on Twitter and I can send you a completed version of impl.dart, provided you don't plan to take 61A now or in the future (if you're a high school student or a current Berkeley student who hasn't taken 61A, I won't provide this to you, even if you have no plans to take it, just as a precaution).
