Install the following opam packages:

opam install caml-mode merlin ocp-indent

Tweak your .emacs file with some or all of the following:

; shift tab to complete
(global-set-key (kbd "S-<tab>") 'company-complete)

Adding UTF-X decoding support to the stdlib

Since 4.06 we have UTF-X encoding support via the Buffer module. The following is a proposal to add UTF-X decoding (and bytes encoding) support with the following goals:

Provide a low-level, allocation-free codec API in bytes. This API provides all the information needed to implement loops for making higher-level UTF-X codec APIs (e.g. Uutf's folding functions) operating on bytes and string values. It's not geared towards the end-user

Switch creation and initialization in opam v2.

The first point for me is that we should as much as possible get to a system where the following basic sequences of steps are possible.

opam switch create bla               # Create switch
opam install non-ocaml-pkg           # Doesn't depend on ocaml
opam install ocaml.V.VV.V+variant

or

This has been integrated in the README of ocaml-depext.

See https://github.com/ocaml/opam-depext/blob/master/README.md

From opam 1.2.2 to 2.0.0 and back with homebrew on macOS

With these instructions you can try 2.0.0 for your day to day work but quickly and safely go back to 1.2.2 if you hit a wall. This maintains both setup entirely isolated.

Going to 2.0.0 for the first time:

> mv ~/.opam ~/.opam-v1 # Save your old setup, use cp -r if you want
