Assignments are allowed in expressions, but they are only allowed on the right side of arithmetic/comparision operators if they are put inside parenthesis - - -data types: -integers and booleans. - -comments: -// and /* */ comments are allowed. - -(For compilation to work the Bool type in Abssyntax has to be removed so the internal haskell type is used) - -shift/reduce conflicts: - -if with else: 1 conflict -An if statement before the else could be reduced to an if statement lacking the else, but the correct thing is to shift it onto the stack. +Files: +Typechecker.hs: Simple modification of the bnfc-generated Testsyntax which calls the type-checking functions. +Typecheck.hs: Contains the type-checking functions typeCheckExp, typeCheckVar and typeCheckStm and some utility functions, responsible for the entire type-checking process. +Abssyntax.hs, Parsyntax.y, Lexsyntax.x,ErrM.hs,Printsyntax.hs,Skelsyntax.hs: The files generated by bnfc, only modification is the removal of the Bool type in Abssyntx.hs so haskell's internal type can be used. typing rules
