我写了一些东西来做我想要的,以防其他人发现它有用:
更新:使用更通用的命令更新此解决方案。
(defun mrc-dired-do-command (command)
"Run COMMAND on marked files. Any files not already open will be opened.
After this command has been run, any buffers it's modified will remain
open and unsaved."
(interactive "CRun on marked files M-x ")
(save-window-excursion
(mapc (lambda (filename)
(find-file filename)
(call-interactively command))
(dired-get-marked-files))))
现在M-x mrc-dired-do-command delete-trailing-whitespace
做我想要的。
如果有人向我指出我不必这样做,我会很高兴,我忽略了一个明显的命令dired-do-command
。
AFAIK dired没有这样的工具,但ibuffer确实 - 使用dired标记你想要影响的所有文件(m
),访问它们(C-u F
),运行ibuffer(M-x ibuffer [RET]
),标记所有缓冲区(m
)和invoke ibuffer-do-eval
(E
),插入要在每个缓冲区中计算的表达式,将它们全部保存(S
)并关闭它们(D
)。
Matt的解决方案很有用,但它有点受限,因为它只允许执行单个命令而不需要任何参数。我想知道是否可以在标记文件上执行宏,并提出了以下dired命令,该命令允许为每个选定文件重放任意(保存)的宏任意次。
使用此命令,我终于能够以非常重要的方式半自动编辑许多文件!
更新:新版本允许执行任意命令(包括宏)和lisp表达式。
