README

Phel is a functional programming language that transpiles to PHP.

It is a dialect of Lisp inspired by Clojure and Janet, designed for building robust applications in the PHP ecosystem.

Example

# Define a namespace
(ns my\example)

# Define a variable with name "my-name" and value "world"
(def my-name "world")

# Define a function with name "print-name" and one argument "your-name"
(defn print-name [your-name]
  (print "hello" your-name))

# Call the function
(print-name my-name)
