Monkey

An interpreter for the Monkey programming language.

Customizations

  • The lexer operates on buffered I/O instead of reading the entire input as a string. This saves on memory usage.
  • Tokens have spans associated with them, so in the case of unknown input, the interpreter can report line and column numbers. Spans mark the beginning and end of a token.
  • Added binary, octal, and hexadecimal integer literal support.
    • 0b0101
    • 0o1234
    • 0xffa4
  • _ support in number literals. Helps when visually parsing numbers.
    • 0b101_101
    • 20_000
