bitmatch 1.0


Richard Jones announced:
I'm pleased to announce the first stable release of bitmatch, version 1.0.

We have a NEW home page:

Bitmatch adds Erlang-style bitstring matching and construction syntax
to OCaml.  It makes parsing binary files, formats and protocols
exceptionally simple.  It has numerous features including 1-64 bit
integers, strings, efficient subsets of bitstrings, big- and little-
endianness, signed and unsigned types, variable-width fields, and
fields with arbitrary bit-level alignment.

You might also want to check out our tool virt-df which uses bitmatch
to parse a wide variety of disk formats:

The source code for the diskimage library is a good place to see
bitmatch in real world usage:;manifest=64ac2a858070b95bc02445b9bb966786e84bebe7;path=/lib/

Bitmatch is available under the GNU LGPL version 2 or later with the
usual OCaml linking exception.

Using folding to read the cwn in vim 6+

Here is a quick trick to help you read this CWN if you are viewing it using vim (version 6 or greater).

:set foldmethod=expr
:set foldexpr=getline(v:lnum)=~'^=\\{78}$'?'<1':1

If you know of a better way, please let me know.

Old cwn

If you happen to miss a CWN, you can send me a message and I'll mail it to you, or go take a look at the archive or the RSS feed of the archives.

If you also wish to receive it every week by mail, you may subscribe online.
