bf-rs

A brainfuck interpreter and debugger written in rust. See the Esolang Wiki entry for more information on the language.

Usage

To execute a program, use the bf-rs binary:

bf-rs [program file]

To provide input, you can either pipe data into the interpreter process or pass the -i flag

echo "input" | bf-rs [program file]
bf-rs -i input.txt [program file]

Debugger

The -d flag enables basic debugging functionality, including stepping through the program and breaking on the special break character #.

bf-rs -d -i input.txt [program file]

Some of the comamnds are:

• re: run to the end of the program
• rle: run to the end of the current loop
• rli: run to the end of the current loop iteration
• r<#>: run the specified number of steps before breaking. For exmaple, r30 would run 30 steps.
• s: step to the next command.
