使用Windows emacs在Cygwin中運行Opam

Question

我在Cygwin中成功安裝了https://github.com/fdopen/opam-repository-mingw，merlin和tuareg。 現在，我已經安裝了Windows emacs並更改了.emacs以啟用用於編輯Ocaml文件的模式。

這是應該如何設置的嗎？ Windows emacs可以與Cygwin OCaml工具一起使用嗎？

如果不是，那么我要求提供詳細信息以在Cygwin中設置emacs。

更新：現在我的init.el是這個

;; Added by Package.el.  This must come before configurations of
;; installed packages.  Don't delete this line.  If you don't want it,
;; just comment it out by adding a semicolon to the start of the line.
;; You may delete these explanatory comments.
(package-initialize)

(setenv "PATH" (concat "c:/OCaml64/bin;" (getenv "PATH")))
(setq exec-path (cons "c:/OCaml64/bin/" exec-path))
(require 'cygwin-mount)
(cygwin-mount-activate)

(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
'(package-selected-packages (quote (company))))
(custom-set-faces

;; OCaml code
(add-hook

  0 -1))
 (add-to-list 'load-path (concat opam-share "/emacs/site-lisp"))

 ;; separate calls, not like setq

 (setq-local show-trailing-whitespace t)
 (setq-local indent-line-function 'ocp-indent-line)
 (setq-local indent-region-function 'ocp-indent-region)
 (merlin-mode)))

 (add-hook 'utop-mode-hook (lambda ()
            (set-process-query-on-exit-flag
             (Get-process "utop") nil)))

cygwin-mount.el在site-lisp文件夾中。

打開.ml文件或鍵入Mx merlin模式時，我看不到任何更改

您確定Tuareg已實際加載嗎？ 如果轉到*scratch* ，請鍵入(locate-library "tuareg")並執行它（當光標位於(locate-library "tuareg")括號后，鍵入C-xC-e ），在回顯區域中您會看到什么？

在您安裝Tuareg的目錄中，應該有一個文件tuareg-site-file.el 。 如果是這樣，請在~/.emacs放入以下行： (load "/path/to/tuareg-site-file")以啟用Tuareg。
