BPSFuck

BPSFuck is a BrainFuck interpreter submitted for the 2021 #BPSCoders Student Contest. It was submitted for contest No. 6.

BrainFuck is an esoteric programming language created in the early 90's. It consists of a set of 8 "commands" which operate on a (theoretically) infinite tape of byte-sized cells, each holding a value from 0 to 255. The commands are as follows:

This list contains only 6 commands, as the remaining two come in delimiting pairs. They are [ and ], and they must come in matching pairs - somewhat like parentheses. Together, they form a loop which repeats the enclosed commands for as long as the current cell (that is, the cell in focus at the beginning of each repition) is nonzero. The above table could be continued as follows:

The definition of either of these commands can be replaced with "unconditional jump to the corresponding [/]" without changing the behavior of the system, but not both.

You can read more about BrainFuck on the Esolang Wiki.

To run this interpreter, you will need the Rust toolchain installed. You can find downloads and installation instructions for supported platforms on the Rust website.

To run the interpreter, invoke the command cargo run -- source.bf in your terminal of choice, where source.bf is the path to the file containing your BrainFuck source code.

Alternatively, you can install the interpreter with by invoking the command cargo install bpsfuck, and then run the interpreter with bpsfuck source.bf.

TODO:

• Support arbitrary chars as no-op
