I just want to announce I've uptated my binary-types package, which is
a library for reading and writing raw "binary" files in lisp. Most
notably, I've removed/changed some of the really ugly parts of the
design (which I wrote as a lisp novice), so I now think the code can
be deemed "usable" by others.

Also note that the syntax of binary-type declarations is somewhat
changed. The syntax now mirrors that of DEFCLASS and DEFSTRUCT (by
BT:DEF-BINCLASS and BT:DEF-BINSTRUCT, respectively), so that you can
add binary read/write capability to such lisp objects by simply adding
binary-type slot-options, for example:

(def-signed raw-number 8 :big-endian) ; RAW-NUMBER is 64-bit signed integer
=> RAW-NUMBER

(def-binstruct raw-complex
(real 0 :bt 'raw-number)
(imag 0 :bt 'raw-number))
=> RAW-COMPLEX

(with-binary-file (stream "x.raw" :direction :output)
(write-binary 'raw-complex stream #S(raw-complex :real 12 :imag 43)))
=> 16 ; wrote 16 octets

(with-binary-file (stream "x.raw" :direction :input)
(read-binary 'raw-complex stream))
=> #s(raw-complex :real 12 :imag 43)
=> 16 ; read 16 octets

% hexdump -C x.raw

Is it available for download somewhere?

Is it generic Common Lisp or implementation-specific?

Duh.. <URL:http://www.cs.uit.no/~frodef/sw/binary-types/>

It is supposed to be generic. I use ACL myself, but I've briefly
checked that it works in clisp and CMUCL.
