Arcyóu

Arcyóu is a LISP-like functional programming language suitable for code golf. It has a large library of potentially useful functions, all one or two characters in length.

Examples

Here are some real PPCG puzzles which Arcyóu can solve in a small amount of bytes:

"Hello, World!":

"Hello, World!"  ; 15 bytes

Golf you a quine for great good!:

Q  ; 1 byte?!

Implement a Truth-Machine:

(?(#(l))(@ 1(p 1))0  ; 19 bytes

Is this number a prime?:

(p?(#(l  ; 7 bytes

Output the current time:

(@ t(pn(zz 1)(p(st %H:%M:%S  ; 27 bytes

Motivation

I would be lying if I didn't admit that I picked the Lisp syntax partially because of how easy it was to parse. But the idea behind Arcyóu is for it to be the Mathematica of golfing languages and have a builtin for everything, a feature which should easily offset the byte cost of parentheses.

Executing code

To run an Arcyóu program you find on the Web somewhere, save it to a file, then run arc.py in a Python 3.x interpreter with the file's name as a command-line argument. Example in a bash shell:

$ python3 arc.py myprogram.arc

You can also run the interpreter without any arguments to start an interactive read-eval-print loop, or REPL, session. Here's an example session:

$ python3 arc.py
