lambda-hs

Sorry for not using github features for features/issues :)

How To Run:

• Load File with Interpreter: stack run -- -i <filename>, e.g. stack run -- -i input/test.lb
• Run Interpreter: stack run or stack run -- -i
• Run a File's Main: stack run -- <filename>, e.g. stack run -- input/test.lb
  • The file must contain the identifier defined in Main.hs. As of writing, it is defined as module_main.

TODO:

• add a test suite for the parser and evaluation
• repl/cli
  • add multilining
  • special commands while in the interpreter (:q, :r)
  • add more commandline options
• evaluation:
  • strictness
• improve error messages:
  • Store line counts for symbols
• operators:
  • Add precedence parsing
  • Allow cool syntax for definitions of infix functions
• add datatype to lambdaline

Issues:

• letexpr and expr are called during assignment parsing (performance)
