Nitpick, put "Your contribution here" below the line? Just more consistent with how we've been doing it.

Lets not shout. So "does not raise error if ..." Thanks :)

No problem.
The idea was not to shout, but to make it more visible when running using "documentation" format.

I am nitpicking, but is this optional :d needed for the spec?

I did to populate declared_params with something more than a Hash.
Just removed as I believe there are other specs covering thath.

Maybe .keys.first is more idiomatic?

Yes, it might.
The case is that I've just move the line that were in the given method as is.
Should I change the line then?
When using `given` and the paramter type is a Hash, a Grape::Exceptions::UnknownParameter is thrown. This is a wrong behavior due to the fact that the method `declared_param?(param)` do not deal properly with params that are hashes (even after flattening the declared params). This commit fixes this by checking if the param is a Hash and thus returning its first key. This approach was already used in other part of the code, so it was extracted and reused on `declared_params?(param)`.

@dblock just did the changes :) |
|
Merged, thank you. |
|
@dblock nice :) What are the plans to cut a release? Is there a particular time-box for that? |
|
No plans, maintainers cut releases fairly frequently so stay tuned. |

I have the same problem, so a gem release with this fix would be pleased |
