A small, optimizing Brainfuck interpreter.

To use the microbf interpreter, simply execute it:

./ubf

It will read from the standard input until it hits an EOF (^D on Linux, Ctrl + Z on Windows), and interpret the input.

To compile microbf, you'll need a C compiler and Meson.

meson build
ninja -C build

libubf and ubfrun will be built to build/meson-out.

microbf can be embedded to create a custom REPL, debugger, or something, but it doesn't have any modularity or application embedding capabilities. Not yet, at least.

#include <ubf_brainfuck.h>

int main(void) {
  // To create a VM, use:
  ubf_vm_t *vm = ubf_init_vm();
  // To interpret code, use:
  ubf_interpret(vm, "+++++[>+++++<-]");
  // After you're done with the VM, don't forget to release its memory:
  ubf_free_vm(vm);

  return 0;
}
