BFInterpreter

Brainfuck interpreter in C

./bf programs/test.bf
Lorem ipsum dolor sit amet.

There are two flags you can give:

-m Print a hexadecimal representation of the memory block left behind by the program
-t Measure and print the time needed to execute the program (including waiting for user input)

Or, if you want to enter some code quickly (like a REPL, just without the L):

./bf -t
Enter a BF program: -[------->+<]>-.-[->+++++<]>++.+++++++..+++.[--->+<]>-----.---[->+++<]>.-[--->+<]>---.+++.------.--------.-[--->+<]>.
