tupcc

This is an interpreter for a LISP inspired programming language called tuple.

• To run a file, pass it as an argument to npm start or node index.js.
• To run in interactive mode, pass the -i or --interactive flag.
• To compile to JavaScript, pass the -c or --compile flag.

If you would like to run a file and interactively run code afterwards, instructions 1 and 2.

The following is a short description of the syntax of the language. To see some more example code, look at the examples/ directory.

• Define a variable (define test 1)
• Change a variable (set test 2) (different from define to help prevent the issue noted below about lack of variable shadowing)
• Evaluate basic operations (+ 1 2)
• Print a value (print (+ 1 2))
• Create a function (lambda (a b) ( {expressions that get evaluated} ))
• Name a function (define sum (lambda (a b) ( (+ a b) )))
• Call a defined function (sum a b)
• Conditional execution (if {cond} ( {exprs if true} ) ( {exprs if false} ))
• Create a list (tuple 1 2 3)
• Loop (while {cond} ( {expressions that get evaluated} ))
