Custom :key_converter?

[sshaw]

Any reason not to accept something callable or allow one to add a converter?

The problem I've found is that some schemas upcase certain words. For example:

Ruby	:camelcase	Wanted
:product_id	ProductId	ProductID
:iso_code	IsoCode	ISOCode

Hey @sshaw, I'm sorry that I did not respond sooner. I completely agree that this is a useful feature, and I'm very glad that @tvon issued a pull request for this functionality.

Do you feel his pull request resolves this? Perhaps we could release a new version of Gyoku with this and then close the issue?

I haven't tried it out but it's better than nuthin'. Some thoughts:

1. May be better to say respond_to?(:call) instead of is_a?(Proc). In some cases people might prefer to use a class.
2. Given Gyoku's interface -i.e., Many calls to Gyoku.xml, it would be nice if one could add converters to FORMULA.

To clarify FORMULA is in XMLKey's singleton class and can't be accessed as if it were scoped to the module. Here's an example:

irb [2.1.2] (ember-test)$ class A 
1{                          class << self
2{                            X = 123
2{                            end
1{                          end
irb [2.1.2] (ember-test)$ A::X
NameError: uninitialized constant A::X
    from (irb):23
    from /Users/sshaw/.rvm/rubies/ruby-2.1.2/bin/irb:11:in `<main>'
irb [2.1.2] (ember-test)$ A.singleton_class::X
=> 123

Was this intentional?
