Motivation

Way before the ReScript compiler moved to OCaml 4.06.1, I liked the richness and interface provided by Jane Street's ppx_let, but I haven't had the chance to target native. It was time to give it a try in JavaScript-land.

Installing

In your terminal, run:

yarn add --dev @leeor/rescript-ppx-let

Edit bsconfig.json:

  "ppx-flags": [
    ["@leeor/rescript-ppx-let/ppx.exe", "-as-ppx"]
  ]

The specifics of using this PPX are very well documented in the original README.
