enhance respond_to? method

[dlupu]

...::MethodWriter#respond_to? and Hashie::Extensions::MethodQuery#respond_to? so that it supports the optional include_private argument - needed to work properly with some other modules like ActiveModel::Validations

Could you link me to the docs where include_private is used? It makes sense that you want the method signature to be compatible, but I noticed you're not actually doing anything with the parameter. Is it safe to assume the value is false?

Hy @jch, thanks for answering.

Actually this is how the super of respond_to is declared (see http://ruby-doc.org/core-1.9.3/Object.html#method-i-respond_to-3F).

So when I tried to use the responds_to? with the include_privateset to true i got an “wrong number of arguments” ArgumentError. My pull request fixes this!

This issue is similar to #20 (same problem, same fix).

So please accept this pull request :)

@dlupu it would be great if you add some specs for that code :)

Sorry this took so long to get around to. I just got commit access to clean things up. Thanks again for the pull! 🍻

Oops, looks like this does not work on ruby 1.8 https://travis-ci.org/intridea/hashie/builds/4736037. I'm going to revert the change, but feel free to open another pull if you find a better fix.

I've merged the change back in. It turns out the problem was from another commit. See #74
