undefined method for Mash in 2.1

[nathany]

We are loading up a YAML file and running Hashie::Mash.new(attrib)on it.

In 2.0.5 a predicate that isn't specified in our YAML/hash is falsey.

In 2.1.0+ we get a undefined method awesome? in this case (unless we specifically put awesome: false).

Can we configure Hashie to provide the old behaviour?

related to #17 & #60.

Can you please write a spec within the existing Hashie specs to describe what you want it to do? I'll help with the implementation.

You mean the test suite? Maybe it would help if I first knew if this was change was intentional. Been through the changelogs.

[dblock]

No code from those issues has been merged, #60 is still open following a discussion in #17. So if change there was, it wasn't intentional and is a regression.

There was a regression that introduced where respond_to? returned the wrong result, and the fix (#147) is on HEAD. That could be your problem - you should try on HEAD and if that didn't fix your issue, definitely write a test that reproduces the problem.

@dblock That is the issue and https://github.com/intridea/hashie/pull/147/files#diff-a351d9f0497eba6d279202565db07edfR333 has a spec to cover it.

Sorry for not trying against HEAD before opening another issue.

Glad that worked!
