INDIGO

INDIGO is an esolang created as it was named after its 6 primary concepts: Increment, Next, Define, If, Goto, and Output. The language was inspired by Lisp, though it has many different features.

Syntax

Any INDIGO program will always have a bracket-based syntax, similar to Lisp. However, the commands are different, there are no lists, and the source code remains uneditable. The only variable types are integers, arrays, and characters.

Features

INDIGO

Function	Arguments + Action
def	name, args : define function
set	cond, block : set variable
inc	var : increment
dec	var : decrement
add	var, var : add (also can be +)
sub	var, var : subtract (also can be -)
mul	var, var : multiply (also can be *)
div	var, var : divide (also can be /)
mod	var, var : modulo (also can be %)
con	cond, block : conditional
whi	cond, block : while
pri	var : print
inp	var : place input in
got	name, args : goto
nex	var : next (can either inc or dec, depending on where var is relative to number in condition)
hal	var/int : halt with value

Examples

Hello World

(pri "Hello world!"
hal 0)

Fizzbuzz

(set x 1
whi (< x 100) (
   con (= (% x 3) 0) (
     pri "Fizz")
   con (= (% x 5) 0) (
     pri "Buzz")
   con (= & (= (% x 5) 0) (= (% x 3) 0) F) (
     pri x)
   nex x)
hal x)
