Dependencies

• Java 9+ (because Map.of is too nice to live without)
• llvm
  • lli for the REPL
  • clang for outputting an executable. Despite what it looks like, clang does not compile any code, it just assembles and links the .ll file. This is because the equivalent shell script is both 6 lines and system dependant.

Optional dependencies

• libreadline (for readline in the REPL)

Differences from upstream:

Lexer

• allows escape characters
• allows numbers to start with a '.'
• disallows multi-line strings
• logs column as well as line number on error
• logs multiple illegal tokens in a row as a single error
• use 'null' instead of 'nil'
• use c-style function declarations instead of 'fun'
• adds several operators:
  • unaries (PLUS_PLUS, MINUS_MINUS)
  • bitwise functions (PIPE, AMPERSAND, PERCENT, CARET)
  • enhanced assignment (PLUS_EQUAL, MINUS_EQUAL, STAR_EQUAL, SLASH_EQUAL, DOT_EQUAL, CARET_EQUAL, PERCENT_EQUAL, AMPERSAND_EQUAL)
