I’m happy to announce I just released version
ppx_yojson is a ppx rewriter that helps you work with
Yojson by allowing you to write concise and expressive json expressions and patterns.
0.2.0 comes with a set of new features which makes it much more usable and less proof-of-concepty. This includes a new extension to write Yojson patterns and anti-quotation for the expressions extension. Hopefully it will attract more users.
Full release notes are available here.
Let me know if you have some feedback or if it lacks anything for you to be able to use it!
