求助，这种elisp里面要怎么写呀？

我有这么个需求，就是希望在特定的快捷键下，添加一个hook函数，然后执行完恢复，也就是把这个hook函数再删掉。

但是我发现，因为这个快捷键对应的操作里面有ivy的调用，可能被终止掉，那么执行完恢复的操作就不会被执行了。

这种需求有没有什么好的办法处理呀？

对于你的第一个需求，doom-emacs有个macro add-transient-hook!

doomemacs/doomemacs/blob/develop/core/core-lib.el#L460


      
            "Add DIRS to `load-path', relative to the current file.
          The current file is the file from which `add-to-load-path!' is used."
            `(let ((default-directory ,(dir!))
                   file-name-handler-alist)
               (dolist (dir (list ,@dirs))
                 (cl-pushnew (expand-file-name dir) load-path :test #'string=))))
          
          
(defmacro after! (package &rest body)
            "Evaluate BODY after PACKAGE have loaded.
          
          
PACKAGE is a symbol or list of them. These are package names, not modes,
          functions or variables. It can be:
          
          
- An unquoted package symbol (the name of a package)
              (after! helm BODY...)
          - An unquoted list of package symbols (i.e. BODY is evaluated once both magit
            and git-gutter have loaded)
              (after! (magit git-gutter) BODY...)
          - An unquoted, nested list of compound package lists, using any combination of
            :or/:any and :and/:all
              (after! (:or package-a package-b ...)  BODY...)

先 hook post-command-hook , 然后判断 this-command 对应的函数和你的快捷键绑定的函数是否匹配，匹配就执行你要的操作
