A simple, complete brainfuck interpreter program that focusses on usability and code readability.

• Uses 8-bit unsigned wrapped cells
• Tape is infinite in both directions
• Outputs cleaned code if verbose and when cleaning was performed
• Code is checked for valid brackets before accepting input
• Takes lines of code through STDIN until an empty line was found
• If the code contains an !, everything afterwards is considered input
• Otherwise takes input from STDIN until an empty line was found
• Does not work for input requiring entirely empty lines (yet!)
• There is no way to alter initial tape state except by prepending code.
• Programs like +[] may cause infinite loops which never crash
• Throws error if there is less input than expected
• If verbose prints the resulting tape as well

Builiding and running requires The Haskell Tool Stack installed.

Run stack build to build, stack run to run the program and stack test to run the unit tests.

Everything else including getting dependencies is taken care of automatically by Stack.
