C!

C! is a Turing-complete esoteric programming language inspired by C++, and was made to simplify it to one letter commands. It requires no whitespace and has basic instructions. It was made by User:PeRsOn.

Overview

C! instruction table

Instruction	Description	Long form
O:: x	outputs x	Out
G:: x	turns x into an input string	Get
P:: x, y	puts a black pixel at x, y	Pixel
F: x,n	makes x a float with value n	Float
S: x,n	makes x a string with n as its value	String
C: x,n	makes x a char with n as its character	Character
I: x,n	makes x an integer with value n	Integer
B: x n	makes x a bool of n	Boolean
T < x	turns x into type T	N/A
+, -	mathematics	N/A
>, <, =	conditionals / comparators	N/A
!, ^, v	boolean operations	N/A
D: x, {n}	makes x a function with instructions n	Define
Q[c, i]	does instructions i if conditional c is true	Question
R[i]	repeats instructions i until E is called	Repeat
E	ends a loop	End
M[x,y,n]	Replaces all instances of y with n in x.	Match
J[x,n]	Concatenates x and n	Join
L[x,n]	gets the nth letter of string x	look

Examples

Truth machine

G::x;
I:x, I<x;
R[
O::x;
Q[x = 0, E];
];

Without whitespace

G::x;I:x,I<x;R[O::x;Q[x=0,E];];

Hello, world!

O::"Hello World!"

Slime fighting game (Inspired by Truttle1)
