plugins - 垂直打开 'undo-tree-visualize side by side to the buffer, and not "”

Question

有什么办法可以让undo-tree-mode在“水平”缓冲区中显示可视化(即 C-x 3 与 C-x 2)？

Answer 1

根据@Tom's suggestion ，我提出了一个仅适用于撤消树的解决方案:

(defadvice undo-tree-visualize (around undo-tree-split-side-by-side activate)
  "Split undo-tree side-by-side"
  (let ((split-height-threshold nil)
        (split-width-threshold 0))
  ad-do-it))

2017-04-29:defadvice 现已弃用，取而代之的是 advice-add。上述解决方案的更新版本如下:

(defun undo-tree-split-side-by-side (original-function &rest args)
  "Split undo-tree side-by-side"
  (let ((split-height-threshold nil)
        (split-width-threshold 0))
    (apply original-function args)))

(advice-add 'undo-tree-visualize :around #'undo-tree-split-side-by-side)
