[ANN] yamerl, a YAML 1.2 parser in Erlang

Hi everyone!

Yakaz is pleased to release yamerl, our YAML parser, written in Erlang.

This parser supports YAML 1.1 and YAML 1.2. The code, documentation and
testsuite are available on GitHub:
  https://github.com/yakaz/yamerl

Beside YAML 1.2 node types, it supports two Erlang-specific node types:
    o  Erlang atom node type.
    o  Erlang fun() node type.

Compared to yamler[1], another parser for Erlang but based on libyaml,
it has the following features and differences:
    o  Support for stream parsing.
    o  Support for YAML 1.2.
    o  Erlang atom autodetection (ie. no tag is specified):
         - yamerl (this one, pure Erlang) tries to represent plain
           scalar as Erlang atom only
         - yamler (libyaml-based) tries to represent both plain
           and single-quoted scalars. This looks more like Erlang
           syntax (where atoms can be unquoted or single-quoted) but
           breaks YAML specification, if I understand correctly.

Also, still compared to yamler, yamerl has the common advantages and
caveats we find in native-code-based vs. pure-erlang-based implementations:
    o  yamerl is slower than yamler.
    o  yamerl may scale better (though I never verified this).
    o  yamerl won't take down the whole VM because of a crash.

Everything is distributed under the terms of the 2-clause BSD license.
