emacs - 如何在 emacs 次要模式下设置注释开始和注释结束？

Question

我正在尝试为Twig创建一个次要模式，语法与 django 非常相似，我想更改注释样式的值以使用 {# 和 #}

如果我做

(setq comment-start "{#")
(setq comment-end "#}") 

运行正确，但是当更改为 lisp 模式时，注释端仍然是“#}”而不是“”

代码在这里

谢谢

Answer 1

You need to make them buffer-local by adding this:

(set (make-local-variable 'comment-start) "{#")
(set (make-local-variable 'comment-end) "#}")

to the define-minor-mode body.

您可以按照有关如何根据次要模式更改光标的答案来做一些事情：

(defvar twig-mode-previous-comments nil
  "Storage for comment start/end that was before twig mode was enabled")
(define-minor-mode twig-mode "twig" :lighter ""
  (unless twig-mode-previous-comments
    (set (make-local-variable 'twig-mode-previous-comments) (cons comment-start comment-end)))
  (if twig-mode
      (progn
        (set (make-local-variable 'comment-start) "{#")
        (set (make-local-variable 'comment-end) "#}"))
    (setq comment-start (car twig-mode-previous-comments))
    (setq comment-end (cdr twig-mode-previous-comments))))
