;;; Commentary:
|
|
|
|
;; tuareg is the preferred ocaml mode for Emacs
|
|
|
|
;; These setups for ocaml assume that you are using the OPAM package
|
|
;; manager (http://opam.ocaml.org/).
|
|
|
|
;; Because of the apparent complexity of getting Emacs environment
|
|
;; variables setup to use opam correctly, it is instead easier to use
|
|
;; opam itself to execute any necessary commands.
|
|
|
|
;; Also, the standard OCaml toplevel usage has been replaced in favor
|
|
;; of UTOP, the universal toplevel, and we assume that you are using
|
|
;; the Jane Street Core libraries rather than the regular OCaml
|
|
;; standard libraries
|
|
|
|
;; The minimum required setup for using Prelude's OCaml setup would be
|
|
;; to install OPAM, and then, minimally `opam install core utop'. A
|
|
;; good getting started guide is available at
|
|
;; https://dev.realworldocaml.org/install.html
