[apps-discuss] draft-snell-merge-patch-08 in Ruby

[Steve Klabnik <[e-mail]>]

Hey there!

James suggested that I post to this list, so here I am.

I'm a committer to Ruby on Rails, and Rails 4 is near a release. One
of the changes in Rails 4 is the usage of PATCH, which means I'm
checking up on various diff media types. Mark Nottingham brought my
attention to draft-snell-merge-patch as a simpler variant of
json-patch.

Anyway, I have a _mostly_ working implementation of the latest draft
as a gem, here: https://github.com/steveklabnik/json-merge_patch .
It's only missing the "Recursively apply rule 2" portion. Hopefully
I'll be finishing it off soon.

I'd say that overall this draft was super simple to implement,
especially given Ruby's (like many scripting languages) ease of
mapping JSON directly to its rich Hash and Array types in the language
core.

I may have one or two thoughts on the language of the spec, but I need
to re-read it and take some notes this time around.
