Parser Implementation Notes:

  • Design the Parser as an isolated component.
  • Bind the Parser component to the Lexer and use Lexer output as input for syntactic analysis.
  • Implement the Abstract Syntax Tree. Design the nodes as Classes.
  • Implement Syntax Analysis using PLY for LALR parser generation.
  • Parser will generate a complete Abstract Syntax Tree representation of the input COOL program.

Implement a custom ParseError Exception class. It should print the line at which the error happened, the probable reason(s) and the character/token at which the error happened.

Finished implementing 10 out of 25 grammar rules. Dissected the expr rule to smaller production rules.
