Monolisp

A lisp-based programming language written for a CompSci class. The name is a play on the word "monolith" and initially referred to the codebase.

Examples

Fibonacci sequence

The program asks the user for a number, and displays N Fibonacci numbers starting from 0.

(setvar n (num (input "Enter a number: ")))

(println "Finding" n "numbers of Fibonacci")

(setvar a 0)
(setvar b 1)
(setvar tmp 0)

(for i (range 0 n)
  (print a "")
  (setvar tmp a)
  (setvar a (+ a b))
  (setvar b tmp)
)

(println)

FizzBuzz

Shows the FizzBuzz sequence from 1 to 100.

Since logical operators don't exist right now, the final if-statement uses multiplication to check if neither are 0.

(for i (range 1 101)
  (if (== (% i 3) 0)
    (print "Fizz")
  )

  (if (== (% i 5) 0)
    (print "Buzz")
  )

  (if (!= (* (% i 3) (% i 5)) 0)
    (print i)
  )

  (println)
)

How to use

Make sure you have Java installed. If one version doesn't work, use a later one.

Once you get that set up, compile the Java source files into class files.

javac *.java **/*.java

Then make sure your program is in program.mono (no CLI interface yet) and type the following to run it.

java Monolisp

Known quirks

Missing features

• No logic operators: not, xor, or are missing.
• No control flow commands: break, continue are missing.

Prod-unreadiness

• Operators intentionally work with only one argument, but should ideally be enforced to a minimum of 2.
• Not all Java errors are handled.
• Types are assumed in many places. For example, == only works with numbers.
• No comments, both in the codebase and in the language.
• User-defined functions are still to be defined.
• It's written in Java.
