emacs以编程方式更改窗口大小

第一种是使用钩子”compilation-finish-functions’,它
是：

[A list of f]unctions to call when a compilation process finishes.
Each function is called with two arguments: the compilation buffer,
and a string describing how the process finished.

这导致了这样的解决方案：

(add-hook 'compilation-finish-functions 'my-compilation-finish-function)
(defun my-compilation-finish-function (buffer resstring)
  "Shrink the window if the process finished successfully."
  (let ((compilation-window-height (if (string-match-p "finished" resstring) 5 nil)))
    (compilation-set-window-height (get-buffer-window buffer 0))))

我对该解决方案的唯一问题是它假定可以通过在结果字符串中找到字符串“finished”来确定成功.

另一种方法是建议’编译 – 处理 – 退出 – 哪个
明确地传递退出状态.我写了这个建议
退出状态为非零时缩小窗口.

(defadvice compilation-handle-exit (around my-compilation-handle-exit-shrink-height activate)
  (let ((compilation-window-height (if (zerop (car (ad-get-args 1))) 5 nil)))
    (compilation-set-window-height (get-buffer-window (current-buffer) 0))
    ad-do-it))

注意：如果在第二次编译时仍然可以看到* compilation *窗口,则在失败时不会调整大小.如果要调整大小,则需要指定高度而不是nil.也许这是你喜欢的(改变第一个例子)：

(if (string-match-p "finished" resstring) 5 (/ (frame-height) 2))

nil被替换为(/(frame-height)2)
