CG's Ramblings

Last Saturday I released version 0.1.0 of cl-bzip2. The project is hosted at common-lisp.net. Its homepage is http://common-lisp.net/project/cl-bzip2/.

cl-bzip2 provides Common Lisp bindings (via CFFI) for libbzip2 — the C library for bzip2 compression/decompression. It provides an easy to use Lisp inteface for the same:

;;; Compression
;;; No values are returned if execution was successful
CL-USER> (bzip2:compress #p"test.txt" #p"test.txt.bz2")
; No value

;;; Decompression
CL-USER> (bzip2:decompress #p"test.txt.bz2" #p"test.txt")
; No value

;;; Using binary streams
CL-USER> (with-open-file (in "test.txt"
                            :direction :input
                            :element-type '(unsigned-byte 8))
          (with-open-file (out "test.txt.bz2"
                               :direction :output
                               :element-type '(unsigned-byte 8))
            (bzip2:compress in out)))
; No value

Hope someone finds it useful. If you have any suggestions for the Lisp API, please let me know (or drop in a mail to the mailing list).
