Whitespace Interpreter

By Brandon Stein

Usage

  • Run make from the root directory to generate the executable whitespace
  • Run the executable using ./whitespace filename, where filename refers to the file containing a whitespace program

The whitespace executable will print the program flow from the given file in plain English. If a value below 128 is pushed onto the stack, the character representation of that value will also be printed in the output. There is also support for non-whitespace characters in programs, which will be ignored by the lexer and treated as comments.

Development Notes and Important Documents

  • Run ocamldep -bytecode *.mli *.ml from the repository root to generate dependency lists for the Makefile
  • Run ocamlyacc -v parser.mly to generate parser.output which can be used to debug the parser
  • OCaml Lexer and Parser Generators
