按编号或字母在帧之间切换

Question

我想创建一个函数，为我提供可编辑或字母选择（1, 2, 3或a, b, c）可切换的帧，而不是手动输入名称。 Aspell将是我能想到的最接近的例子。

有人可以分享一下如何做到这一点的例子吗？以下函数的第6行到第14行动态创建所有可用帧名称的列表。可以找到与帧切换相关的附加功能here

(defun switch-frame (frame-to)
  (interactive  (list (read-string (format "From: (%s) => To: %s.  Select: "
    ;;  From:
    (frame-parameter nil 'name)
    ;;  To:
    (mapcar
      (lambda (frame) "print frame"
        (reduce 'concat
          (mapcar (lambda (s) (format "%s" s))
            (list "|" (frame-parameter frame 'name) "|" )
          )
        )
      )
    (frame-list) )
   )))) ;; end of interactive statement
  (setq frame-from (frame-parameter nil 'name))
  (let ((frames (frame-list)))
    (catch 'break
      (while frames
        (let ((frame (car frames)))
          (if (equal (frame-parameter frame 'name) frame-to)
              (throw 'break (select-frame-set-input-focus frame))
            (setq frames (cdr frames)))))) )
  (message "Switched -- From: \"%s\"  To: \"%s\"." frame-from frame-to) )

编辑（2014年11月13日）：以下是使用ido-completing-read的修订功能：

(defun ido-switch-frame ()
(interactive)
  (when (not (minibufferp))
    (let* (
        (frames (frame-list))
        (frame-to (ido-completing-read "Select Frame:  "
          (mapcar (lambda (frame) (frame-parameter frame 'name)) frames))))
      (catch 'break
        (while frames
          (let ((frame (car frames)))
            (if (equal (frame-parameter frame 'name) frame-to)
              (throw 'break (select-frame-set-input-focus frame))
              (setq frames (cdr frames)))))))))

Answer 1

1. This answer描述了 Icicles 命令icicle-select-frame，它允许您使用完成按名称选择框架。

2. 还有冰柱命令icicle-other-window-or-frame（C-x o），它结合了命令icicle-select-frame，other-frame和{{1 }}。它允许您按名称或顺序选择窗口或框架。

   • 没有前缀arg或非零数字前缀arg： 如果所选框架有多个窗口，那么这就是 other-window。否则，它是other-window。

   • 使用零前缀arg（例如other-frame）： 如果所选框架有多个窗口，那么这就是 C-0框架中的窗口作为候选人。 否则（单窗口框架），这是icicle-select-window。

   • 使用普通icicle-select-frame： 如果所选框架有多个窗口，那么这就是 C-u所有可见帧的窗口为。{1}} 候选人。否则，这是icicle-select-window。

Answer 2

根据操作系统的不同，可能需要在功能结束时使用(select-frame-set-input-focus chosen-frame)而不是select-frame / raise-frame。

  

(defface frame-number-face
  '((t (:background "black" :foreground "red" )))
  "Face for `frame-number-face`."
  :group 'frame-fn)

(defface frame-name-face
  '((t ( :background "black" :foreground "ForestGreen")))
  "Face for `frame-name-face`."
  :group 'frame-fn)

(defun select-frame-number ()
"Select a frame by number -- a maximum of 9 frames are supported."
(interactive)
  (let* (
      choice
      chosen-frame
      (n 0)
      (frame-list (frame-list))

      (frame-name-list
        (mapcar
          (lambda (frame) (cons frame (frame-parameter frame 'name)))
          frame-list))
      (frame-name-list-sorted
        (sort

            frame-number-list)
          " | "))  )
    (message "%s" pretty-list)
    (setq choice (read-char-exclusive))
    (cond

    (setq chosen-frame (car (nth (1- choice) frame-name-list-sorted)))
    (when (> choice total-frames)
      (let* (
          (debug-on-quit nil)

        (signal 'quit `(,quit-message ))))
    (select-frame chosen-frame)
    (raise-frame chosen-frame)
    chosen-frame))
