OCaml PPX deriver for deriving `show` based on `ppxlib`.

This library reimplements the show plugin from ppx_deriving directly as a ppxlib deriver.

Usage

ppx_show can be used with dune by using the preprocess field. ppx_show_runtime has to be added to runtime libraries.

(executable
  ...
  (preprocess (pps metapp.ppx))
  (libraries ppx_show_runtime)
  ...)
