定义匿名函数以绑定到邪恶领袖密钥

Question

使绑定到键t在下面的工作所需的语法是什么？

(evil-leader/set-key
  "f" 'find-file
  "o" 'other-window
  "b" 'switch-to-buffer
  "k" 'kill-buffer
  "1" 'delete-other-windows
  "2" 'split-window-below
  "3" 'split-window-right
  "c" 'winner-undo
  "w" 'enlarge-window-horizontally
  "t" (lambda () (enlarge-window 5))
  "d" 'ido-dired)

我尝试了几种变体，包括引用整个表达式，仅引用enlarge-window调用等。也许你不能这样做？

Answer 1

该函数必须是交互式的。

例如

(evil-leader/set-key
  ...
  "t" (lambda () (interactive) (enlarge-window 5)))

旁注：如果冗长让您感到烦恼，此宏可以解决此问题：

(defmacro λ! (&rest body)
  `(lambda () (interactive) ,@body))
(evil-leader/set-key
  "t" (λ! (enlarge-window 5)))
