A esolang is a programming language that is not intended to be used for practical purposes. They are often used as a joke, educational tool, or as a challenge to write programs in. here is a list with most of them.
This repository is a collection of esolangs interpreters.
| Name | Description | Goto readme |
|---|---|---|
| Brainfuck | A simple esolang that uses only 8 instructions. | README.md |
| Spyrodecimal | It was designed to have only numbers as instructions. | README.md |
| Barely | The goal is to have as small of a interpreter as possible. | README.md |
Brainfuck is a simple esolang that uses only 8 instructions. It is Turing complete and one-dimensional.
The instructions are:
| Command | Description |
|---|---|
> |
Increment the data pointer (to point to the next cell to the right). |
< |
Decrement the data pointer (to point to the next cell to the left). |
+ |
Increment (increase by one) the byte at the data pointer. |
- |
Decrement (decrease by one) the byte at the data pointer. |
. |
Output the byte at the data pointer. |
, |
Accept one byte of input, storing its value in the byte at the data pointer. |
[ |
If the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command. |
] |
If the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command. |
# |
Print the current memory state from the data pointer to data pointer + 16 |
Hello World:
++++++++++[>+++++++>++++++++++>+++>+<<<<-]>++.>+.+++++++..+++.>++.<<+++++++++++++++.>.+++.------.--------.>+.>.Spyrodecimal is a esolang that was designed to have only numbers as instructions but it knows also some letters as instructions. It is Turing complete and one-dimensional. Made by Spyro543.
The instructions are:
| Command | Description |
|---|---|
0 |
Pauses for 1/10 seconds |
1 |
Outputs the ASCII byte in memory |
2 |
Increase memory |
3 |
Decrease memory |
4 |
Store input in memory |
5 |
Print new line |
6 |
generate random number between 1 and 256 and store it in memory |
7 |
Moves the program pointer back the amount of times the memory is |
8 |
Resets memory to 0 |
9 |
Moves the program pointer forward the amount of times the memory |
q |
Quits the interpreter |
x |
Quits the program |
s |
Stores memory in 1 of 6 variables (a, b, c, d, e, f). Variables are not effected by 8 |
r |
Loads memory from 1 of 6 variables (a, b, c, d, e, f) into memory |

Barely is a esolang that had the goal to have as small of a sturing complete interpreter as possible. And the original was just 59 bytes in size. it is Turing complete and one-dimensional.
The instructions are:
| Command | Description |
|---|---|
] |
Exits program |
^ |
If accumulator is 0, execute b instruction |
b |
Add jump to ip |
g |
Accumulator is memory |
h |
Add 71 to accumulator |
i |
Increment memory pointer |
j |
Increment accumulator |
k |
Decrement jump |
m |
memory is accumulator |
n |
Decrement memory pointer |
o |
Decrement accumulator |
p |
Add 10 to jump |
t |
Store user input in accumulator |
x |
Output accumulator |
f || l || q || s |
No operation |
~ |
No operation also marks start of program |
