Principles of Programming Assignment: Project

Objective

Implement a language E interpreter following project.pdf.

Implement the functions in src/main/scala/impl, which are currently left blank as ???

WARNING:Please read the restrictions below carefully.

If you do not follow these, your submission will not be graded.

DO NOT FIX THE FILES WITHOUT EXPLICIT INSTRUCTIONS
- You can ONLY modify the functions with ??? in src/main/scala/impl
- Your code will not be compiled if you modify any of the codes other than ???.
Do not use the keyword var (except we've already given). Use val and def instead.
Do not use mutable data structures.
- You can see useful data structures from this link: Scala 3 Collections
- From the above link, you are forbidden to use the classes in scala.collection.mutable.
Do not use while.

Again, your score will be zero if you do not follow these rules.

sbt run # run a REPL of language E
sbt test # test TestSuite.scala

We will offer test cases (TestSuite.scala) until 11/30.

For all assignments, we will test your code only with the given files in src/main/scala directory.
All the additional files you've created will be lost!!
We will check git logs of the main branch, and grade the latest commit before the due date.

git add src
git commit -m 'Write some meaningful message'
git push

Branch errata is protected. If any correction would be appeared on the code, I will update errata branch.
If you find any ambiguity from the description, write an issue to the GitHub issue tracker.
