Summary

This program is an interpreter for a simple programming language. It type checks and has informative error messages. It uses 'Bison' and 'Flex' to create the parser. The type checker and interpreter are written in C++. I wrote it mostly to see if I could. At this time it has very little practical use.

Acknowledgements

This project grew out of a class I took on Programming Languages at the University of British Columbia (CPSC 311 taught by Gregor Kiczales). The simple language and interpreter ideas are straight out of the interpreter we wrote in class (in Scheme) but the implementation in C++ is my own.

Other Notes:

Examples:

let x = 5
  in x
Result Type: int
Result Value: 5
let p = proc (int a)
          if =(a, 5) then false else true
  in call p(6)
Result Type: bool
Result Value: true
let p = proc ([int - int] q, int a)
          =(call q(a), a)
  in call p( proc (int b) b, 5)
Result Type: bool Result Value: true

let x = 3
  in begin
      set x = 4,
      x
     end
Result Type: int
Result Value: 4
