[Caml-list] [ANNOUNCE] OCaml Bitstring 2.0.2

2010-01-09 Thread Richard Jones 

Bitstring is a syntax extension which adds Erlang-style bit matching
and construction to OCaml programs.  You can use this to efficiently
and safely parse communication protocols and binary file formats.

Bitstring handles integers, booleans, strings, sub-bitstrings, big-,
little- and native-endianness, signed and unsigned types,
variable-width fields, fields whose width depends on values in
previous fields, fields with arbitrary bit alignment, forward offsets,
when-clauses, checked expressions, security against buffer overflows
and DoS, and lots more.

Example:

  let bits = Bitstring.bitstring_of_file image.gif in
  bitmatch bits with
  | { (GIF87a|GIF89a) : 6*8 : string; (* GIF magic. *)
  width : 16 : littleendian;
  height : 16 : littleendian } -
  printf %s: GIF image is %d x %d pixels filename width height
  | { _ } -
  eprintf %s: Not a GIF image\n filename

The latest version is 2.0.2 which fixes a number of compilation
problems related to OCaml 3.11, and incorporates some unofficial
patches which were floating around.  (Note that bitstring 2.0.0 is
known to be broken on Debian).

Re: [Caml-list] [ANNOUNCE] OCaml Bitstring 2.0.2

2010-01-09 Thread Matthieu Dubuget 
For those who would want to use bitstring on mingw, I had it compiled ok 
with the following:

cp byteswap.in.h byteswap.h
sed -i -e 's/-Werror -fPIC//' Makefile.in
sed -i -e 's/open_in/open_in_bin/' pa_bitstring.ml 
create_test_pattern.ml bitstring_objinfo.ml

./configure CFLAGS=-mno-cygwin
make



The test target is also buggy on mingw.

But the library is working ok

Salutations

Matt
