In the meantime, I've attached a dot-emacs and dot-merlin files that I think work nicely on a mac. The one thing you need to do is to add this line to your .profile file:
eval `opam config env` The dot emacs depends on this being in place for figuring out where to find all the executables stashed in the .opam directory. The pre-reqs for this to work is getting tuareg downloaded and in the proper path (right now, I assume ~/.elisp/tuareg-mode), and installing some opam packages: opam install core async merlin utop ocp-indent This should give you merlin, ocp-indent, tuareg, and utop support, all nicely integrated. Note that the .merlin file needs to go in the directory where you're editing code (and really, in every directory where you're editing code.) And the .merlin assumes that you're using ocamlbuild (or corebuild) and so are putting your build artifacts in _build. I'm hoping this is helpful. y On Thu, Jan 22, 2015 at 8:42 PM, Yaron Minsky <[email protected]> wrote: > On Thu, Jan 22, 2015 at 8:25 PM, Louis Gesbert > <[email protected]> wrote: >> Thanks for the feedback.
