在Emacs下可以使用caml模式下的tuareg字体吗？ [英] Is it possible to use the font of tuareg in caml-mode under Emacs?

问题描述

对于缩进if，我必须使用 Caml-mode 在Emacs下。

For Indentation of "if", i have to use caml-mode under Emacs.

但是我发现 tuareg 比 caml-font 更加多彩，所以我的问题是是否可以使用 tuareg 在 caml-mode 。

But I find the font of tuareg is more colorful than caml-font, so my question is whether it is possible to use the font of tuareg in caml-mode.

另外，使用当前的。emacs 需要 caml-font ，当我打开一个 .ml 文件，一些行（特别是在文件的开头）不突出显示。如果我去那些行，修改它们，他们会改变他们的颜色。有没有人会告诉我如何解决这个问题？

Also, with the current .emacs which requires caml-font, when I open a .ml file, some lines (especially in the beginning of the file) are not highlighted. If I go to those lines, modify them, they will change their color. Could anyone tell me how to fix that problem?

另外，除了 tuareg之外，还有一些更好的ocaml程序的字体和 caml-font ？

非常感谢！

推荐答案

你的意思是你喜欢的颜色更好或更多的颜色？

Do you mean that you like the colors better or that their are more colors?

如果是后者，可能很难用caml模式使用tuareg字体锁定，虽然我只看了一下这两个。

If the latter, it's probably difficult to use tuareg font-locking with caml-mode, though I only looked at the two a little bit.

如果是前者，您可以简单地自定义 caml-mode 使用的脸部，以使用更好的脸部（我的意思是字体或颜色）。使用足够新的emacs，将光标放在要更改的面上，然后键入 M-x custom-face RET 。它会建议你所在的脸的名字，所以再次返回。然后你可以以任何你想要的方式改变脸部。作为第一步，您可以保持 tuareg.el 打开并检查所在的脸，例如

If it's the former, you can simply customize the faces used by caml-mode to use better faces (by which I mean typeface or "color"). With a sufficiently new emacs, put your cursor on the face that you want to change and type M-x customize-face RET. It will suggest the name of the face that you are on, so hit return again. Then you can change the face in any way you want. As a first step you might keep tuareg.el open and check what faces are there, for example

(defface tuareg-font-lock-governing-face
  '((((background light)) (:foreground "blue" :bold t))
    (t (:foreground "orange" :bold t)))
  "Face description for governing/leading keywords."
  :group 'tuareg-faces)

是用于let的脸的定义，所以你只需把你的光标放在let， Mx自定义面RET RET ，然后将前景更改为蓝色并打开粗体（假设您有浅色背景）。不要忘记保存它。

is the definition of the face used for let, so you would just put your cursor on let, M-x customize-face RET RET, then change the foreground to blue and turn on bold (assuming you have a light background). Don't forget to save it.

或者，您可以编辑 caml-font.el 并更改 caml-font-lock-keywords 部分使用您喜欢的字体（可能来自tuareg）。如果要添加到 .emacs ，那么您应该将其更改为（setq caml-font-lock-keywords ...）。

Alternately, you can edit caml-font.el and change the caml-font-lock-keywords section to use the fonts you like (which could be from tuareg). If you want to add to your .emacs instead then you should change it to (setq caml-font-lock-keywords ...).

(defconst caml-font-lock-keywords
  (list
   ...
;definition
   (cons (concat
          "\\<\\(a\\(nd\\|s\\)\\|c\\(onstraint\\|lass\\)"
          "\\|ex\\(ception\\|ternal\\)\\|fun\\(ct\\(ion\\|or\\)\\)?"
          "\\|in\\(herit\\|itializer\\)?\\|let"
          "\\|m\\(ethod\\|utable\\|odule\\)"
          "\\|of\\|p\\(arser\\|rivate\\)\\|rec\\|type"
          "\\|v\\(al\\(ue\\)?\\|irtual\\)\\)\\>")
         ;; 'font-lock-type-face)
         'tuareg-font-lock-governing-face)
   ...
   ))
