Alexander Shorin commented on COUCHDB-3093:
-------------------------------------------

Ideally, PATCH method should work with [JSON Patch|https://tools.ietf.org/html/rfc6902] specification. There is no reason to invent something else for this.

> I know I could do update handler (and I have create my own like this https://gist.github.com/Thaina/9e4d8d6643b3dee06903350ffc5d9714)
> but it would be more efficient to just support natively. It would make all of us write PATCH in standard
> And I would like to suggest that you should natively support special string as function. something like 2 underscores for activate special function
> suppose current doc is { "number" : 1 }
> then patch with { "number" : "_-2_","text": "text","_usText_":"_=\"_usText_\"_" }
> result into { "number" : -1,"text": "text","_usText_":"_usText_" }
> So it could support append,prepend,insert,replace and delete
> Also I wish PATCH would return the updated diff
