如何从Magit中的大块中删除尾随空格？

Question

Emacs（v21后）包含来自文件的delete trailing whitespace函数。我如何在Magit临时区域（delete-trailing-whitespace）中提供magit-status，以便我可以删除单个黑客或整个文件中的尾随空格？

Answer 1

这是Sean的片段，根据Magit v2进行了调整：

(defun my-magit-delete-trailing-whitespace-from-file ()
  "Remove whitespace from the current file."
  (interactive)
  (save-excursion
    (magit-diff-visit-file-worktree (magit-file-at-point))
    (delete-trailing-whitespace)
    (save-buffer)
    (kill-buffer))
  (magit-refresh))

Answer 2

感谢@ tarsius的精彩演绎！我设法调整它以删除线上的尾随空格。这需要＆＃39; ws-trim＆＃39;包已安装。

(defun my-magit-delete-trailing-whitespace ()
  "Remove whitespace from the current file."
  (interactive)
  (save-excursion
    (magit-diff-visit-file-worktree (magit-file-at-point))
    (ws-trim-line nil)
    (save-buffer)
    (kill-buffer))
  (magit-refresh))

(add-hook 'magit-status-mode-hook
 (lambda ()
   (local-set-key [deletechar] 'my-magit-delete-trailing-whitespace)))

我绑定了删除键，因为它不会用于magit-status-mode中有用的任何内容。
