yaml vs perl complexity ( was Re: [Catalyst] JSON instead ofYAML? )

[James FitzGibbon]

>From the YAML docs:

I am currently working on 3 different YAML implementations.

YAML::Lite

    The point of YAML::Lite is to strip YAML down to the 90% that people use
most and offer that in a small, fast, stable, pure Perl form. YAML::Lite
will simply die when it is asked to do something it can't. 


So perhaps just a private frozen YAML 0.39 will do the trick until
YAML::Lite is ready.

We'd still need a parser/validator/importer/exporter/etc for this
subdialect, since we wouldn't want to eval it directly if we're trying
to restrict what people can do with it.  Which puts us back in the
boat of writing Yet Another YAML-Like Module (Catalyst::YAYAMLLM
anyone? :) ).

YAML was a great solution for what Cat needed, it's just the Spiffy thing...

I say branch a copy of a good version of YAML, apply any relevant
fixes that have occured during Spiffy-time that apply to old YAML
also, and call it Catalyst::YAML, for now - roll it into the Cat
distribution instead of publishing it seperately.  I know - the
comparisons to the CDBI frozen thing....

Or we go with JSON, or something like Config::Scoped.  Whatever :)
