Yet another Brainfuck interpreter, this time written in Common Lisp.
This has only been tested with SBCL. Also, you may want to install Quicklisp, if you still haven't.
In order to compile cl-bff into a single binary, you just need to call make bin:
$ make bin
...
;;; Computing Hangul syllable namesSTYLE-WARNING:
Defining (*DEFAULT-MEMORY-SIZE*) as a constant, even though the name follows
the usual naming convention (names like *FOO*) for special variables

done]
$ ls bin/
cl-bff
$
After you've compiled the code, you can simply run bin/cl-bff:
$ ./bin/cl-bff t/examples/hello.bf
Hello, world!
$ ./bin/cl-bff t/examples/hello.bf --mem-size 30
Hello, world!
You can test the code against all the Brainfuck source files in tests/ by running the following make target:
$ make test
-- snip --
1 Bottle of beer on the wall
1 Bottle of beer
Take one down and pass it around
0 Bottles of beer on the wall
./bin/cl-bff t/examples/hello.bf
Hello, world!
./bin/cl-bff t/examples/hello4.bf
Hello World!
./bin/cl-bff t/examples/hello5.bf
Hello World!
[test] finished!
$
You can run the unit tests with make unit target:
$ make unit
TEST-SANITIZE: 1 assertions passed, 0 failed.
TEST-IS-VALID-OPERATOR: 2 assertions passed, 0 failed.

Still need to add more, though.
