Hello Brainfuck

A greeting tool written entirely in Brainfuck - the famously minimalist esoteric programming language created by Urban Müller in 1993.

About Brainfuck

Brainfuck has only 8 commands:

• > - Move pointer right
• < - Move pointer left
• + - Increment cell
• - - Decrement cell
• . - Output cell as ASCII
• , - Input to cell
• [ - Jump past ] if cell is zero
• ] - Jump back to [ if cell is non-zero

Everything else (including comments) is ignored.

How It Works

The program builds each ASCII character using multiplication loops. For example, to print H (ASCII 72):

>+++++++[-<++++++++++>]<++.[-]

This creates 7 in a cell, multiplies by 10 (using a loop), adds 2, then prints.

Usage

CLI

enact run enact/hello-brainfuck

MCP (for LLMs/Agents)

Call enact__hello-brainfuck with no arguments.

Output

Returns JSON:

{"message":"Hello from Brainfuck!"}

Why?

Because we can. And because every tool registry deserves at least one Brainfuck program.
