This is a compiler for a subset of the Manatee Programming Language.

The idea is for students to fork this repository to build their own compilers and interpreters for the full language. After all, it can be argued that extending a compiler for a small language has more pedagogical value that having students implement everything from scratch.

Manatee is described at http://cs.lmu.edu/~ray/notes/manatee.

Here are some of the full language features not implemented in this subset:

• Modules --in grammar
• Codepoint escapes in character and string literals
• Object types and literals --in grammar (+expanded Type.java for object types)
• Streams for reading and writing --Gone
• Increment and decrement statements --in grammar
• Parallel assignment --in grammar
• Exceptions --in grammar
• Timers --in grammar
• unless and until modifiers --in grammar
• Bitwise operators --in grammar
• Modulo operator --in grammar
• Divides operator --in grammar
• Bitwise complement operator --in grammar

Entities that need to be added:

• IdentifierExpression --Added constructor and getters
• Import --Added constructor and getters
• FailStatement --Added constructor and getters
• UntilLoop --Added constructor and getters
• ModifiedStatement.ModifierType.UNLESS
• ModifiedStatement.ModifierType.UNTIL
  • (The previous two are members of enum ModifierType in ModifiedStatement)

Resubmit for Homework2:

• IncrementStatement.java Entity
• CallStatement Entity (for wait time addition)
• TryStatement.java
• manatee.jj
  • Parallel Assignment
  • Increment/Decrement
  • TYPEDEC ( where TYPE() used to be)

Homework3: analyze methods that need to be filled out/updated:

• Type (for object types) --done
• IncrementStatement --done
• CallStatement (for wait time) --done
• ParallelAssignmentStatement --done
• TryStatement --done
• FailStatement --done (analyzes expression at least)
• UntilLoop --done
• Import
