[Caml-list] [ANN] Atdgen 1.2.0 + tutorial, OMake/Make support

[Martin Jambon <martinj@mylife.com>]

Hello list,


I have the pleasure to officially announce this new release of Atdgen.
Atdgen is a tool that generates optimized OCaml code from type
definitions, primarily for data serialization:

  http://oss.wink.com/atdgen/

Atdgen supports one text format, JSON, and one binary format, Biniou,
which retains most properties of JSON.

  JSON specification: http://json.org
  Biniou specification: http://martin.jambon.free.fr/biniou-format.txt


What's new
----------

* a tutorial: http://mylifelabs.github.com/atdgen-tutorial.html

* new command-line modes (-t, -b, -j, -v) and new conventions that make
it easier to split groups of type definitions into multiple files and
OCaml modules. Existing users of Atdgen are encouraged to switch to this
new model, described in the tutorial.

* a validator mode (-v) which produces code that calls user-specified
validators on the nodes of data structures to validate.

* OMake support: https://github.com/MyLifeLabs/atdgen-omake

* GNU Make support: https://github.com/MyLifeLabs/atdgen-make


Development status
------------------

Atdgen is being developed at MyLife (http://www.mylife.com) where we use
it routinely to process and serve terabytes of rich data.

The source repository is publicly hosted on GitHub:

  https://github.com/MyLifeLabs/atdgen


Technology used
---------------

* type definition parsing (atd package): ocamllex + menhir
* JSON parsing (yojson package): ocamllex, some Obj
* Biniou parsing (biniou package): handwritten OCaml, some Obj
* pretty-printing (atd, yojson, biniou): easy-format, relying on Format
* not-too-ugly-printing OCaml code (atdgen) uses simple technique
implemented here:
    https://github.com/MyLifeLabs/atd/blob/master/atd_indent.mli
    https://github.com/MyLifeLabs/atd/blob/master/atd_indent.ml

(Atdgen does not use Camlp4)



Enjoy!
