hlisp

Learning about parser combinators by implementing a tiny lisp.

How to use

No REPL yet. The Main module exports a utility interpret function that will read in a lisp string and evaluate it.

Progress

• Numbers (only integers are supported for now)
• Strings
• Bools (denoted #t and #f)
• Lambdas ((lambda x (+ x x)))
• Let bindings ((let x 5 (+ x x)))
• Conditionals ((if (= (+ 2 2) 5) "Big Brother won" "Still the captain of my soul"))
• Quoting (hurts my brain) ((quote (1 2 3)))
• REPL

Standard library

hlisp supports a vast standard library:

• Integer arithmetic: +, -, *
• Equality testing: =
