Option to autoconvert camelCase to snake_case

[kiddten]

Is it possible to add such option to Config?
I have some 3rd party json with keys in camelCase but that isn't appropriate naming for attributes in dataclass

Not only that, it would be awesome to support removing trailing spaces from keys (e.g. my key is called from so I want to map it to from_

Hi @kiddick - thank you very much for reporting issue.

Unfortunately, I don't think it's a good idea to add any "data" processing features into dacite. I want to keep it simple.

I'm pretty sure that there are plenty of "camelCase-to-snake_case" libs in PyPI. You just have to call such lib before passing data to dacite.

@konradhalas -- thanks so much for this library! I am trying to use it to convert a large structure loaded from yaml. As you note, converting individual strings is not a problem. However, walking the data structure and recursively converting them before passing the structure to dacite seems like duplicate work.

Perhaps you could consider a convert_keys option, that took a function to pre-process keys as they were encountered during conversion. That way, I could pass my favorite "camelCase-to-snake_case" function (or for that matter, "arbitrary string to snake case slug" function) without you having to wade into "processing data". (?) Happy to create a separate feature request if this seems more doable.
