PHp Interpreted Lisp.

Phil is a LISP dialect loosely based on the syntax used by Clojure.

Usage

Phil can either be invoked by running bin/phil or using ./phil.phar (coming soon). Running this will open the REPL where you can run simple commands. The binary also accepts a file path to run code contained in a script file.

Example Code

As with all LISP dialects the pattern is (functionname args), so to run a simple Hello World app you run:

(println "Hello, World")

or to add a list of numbers together:

(+ 1 2 3 4) ; returns 10

Functions can be declared using the defn keyword found in Clojure:

(defn sayHello (name) (println (+ "Hello, " name)))

(sayHello "Bob") ; returns "Hello, Bob"

Recursive functions and conditionals are also supported allow for code such as:

(defn length (xs)
	(if
	    (= 0 (count xs))
	    0
	    (+ 1 (length (rest xs)))
    )
)

(length '(1 2 3 4 5)) ; returns 5
