ABG

ABG is an esoteric programming language made by User:ChuckEsoteric08 that uses only 4 commands: a, b, g and c.

Commands

Command	Meaning
a	Increment the current cell and move the pointer to the right.
b	Decrement the current cell.
g	Move the pointer to the left and go to the matching c if the current value equals 0.
c	Go to the matching g if the current cell value does not equal 0.

There is also command for debug: # which outputs cell. Implementing it is unnsecesary.

gc

is just move pointer to the left and not start loop because there isn't anything between g and c If you want loop that does nothing, then you need this code:

g c

Examples

Infinity loop

agcg c

It is can be translated to BF like this:

+><[]

agc is same as + in BF. So BF equivalent is this:

+[]

Cat program

An infinitely repeating cat program is implemented in the following:

d#agd#aagcc

Truth-machine

This program implements a truth-machine:

d#bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbag
agcagcagcagcagcagcagcagcagcagcagcagcagcagcagcagcagcagcagcagc
agcagcagcagcagcagcagcagcagcagcagcagcagcagcagcagcagcagcagcagc
agcagcagcagcagcagcagcagc
#bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbaagcc

ABGAD

ABGAD is ABG, but with input command d, # outputs as ASCII and command e which halts program.

Computational class

BF can be translated to ABG like this:

BF	ABG
+	agc
-	b
>	ba
<	gc
[	bag
]	c

Interpreter

• Common Lisp implementation of the ABG and ABGAD programming language.
