A gem that lets one easily convert hash keys between snake_case and camelCase.
None.
As an example:
h = {something: "blah", two_words: "foo", nested_hash: {foo_bar: "something"}}
h.transform_key_case(:lcamel)
=> {"something"=>"blah", "twoWords"=>"foo", "nestedHash"=>{"fooBar"=>"something"}}
This will return a new hash with the keys transformed into the desired case. Transformed keys will always be of type String.
There is corresponding bang method transform_key_case! that operates in-place.
Valid case arguments are:
:lcamel
:lower_camel
:ucamel
:upper_camel
:snake
Both methods also accept an optional deep keyword argument. By default, transformations are deep. This can be turned off by setting that argument to false.
h.transform_key_case(:lcamel, deep: false)
=> {"something"=>"blah", "twoWords"=>"foo", "nestedHash"=>{:foo_bar=>"something"}}
Note that nested hashes may still have non-String keys since the method does not operate on them.
