Zig Brainfuck interpreter

A Brainfuck interpreter written in Zig

Build

Using Zig of course! Here are some examples of build commands:

# Build interpreter
zig build

# Run the tests
zig build test

# Disable value and pointer overflow wrapping
# If the value in the stack overflows, it will stay the same
# If the pointer to the stack overflows, it will panic and return an error
zig build -Dwrap_addr_overflow=false -Dwrap_val_overflow=false

# Non-debug build (debug build will return information about the stack on each Brainfuck call)
zig build -Doptimize=ReleaseFast

Usage

The interpreter takes any number of argument, each one can be a Brainfuck program. You can also pass a file with the -file parameter:

# Run an Hello world program
bf ">+++++++++[<++++++++>-]<.>+++++++[<++++>-]<+.+++++++..+++.[-]>++++++++[<++++>-]<.>+++++++++++[<++++++++>-]<-.--------.+++.------.--------.[-]>++++++++[<++++>-]<+.[-]++++++++++."

# Run the sierpinski example
bf -file examples/sierpinski.b

EOF can be sent with Ctrl+D on UNIX systems, Ctrl+Z then Enter on Windows systems.
