OCamlReformat.el

Goal

Proof of concept that aims to simplify the Elisp code of ocamlformat.el by using the library reformatter.el.

Basic configuration example

(add-to-list 'load-path "path_to_ocamlreformat")
(add-to-list 'load-path "path_to_reformatter")
(require 'ocamlreformat)
;; format the buffer on save
(add-hook 'tuareg-mode-hook #'ocamlreformat-on-save-mode)
;; bind Ctrl-Meta-\ to format a valid region (by default, bound to `indent-region')
(define-key tuareg-mode-map (kbd "C-M-\\") 'ocamlreformat-region)

Build

Use Makefile from the project root directory. Main targets:

• make - Download a copy of reformatter.el and compile ocamlreformat.el
• make test-* - Start an new instance of Emacs with a minimal configuration
• make clean - Remove reformatter.el dependency and clean generated files.

What's left to do

• Support ocamlformat-show-errors
• Package available from MELPA?
• Check it is a drop-in replacement of the current ocamlformat.el. So far, naming of the customizable variables is kept the same apart from the prefix (from ocamlformat to ocamlreformat).
