[英]Copy emacs shell input list to a buffer or file
I have an emacs shell buffer and would like to save each command that I have input as a new line of text in a new temporary buffer. 我有一个emacs shell缓冲区,想将我输入的每个命令另存为新的一行文本到新的临时缓冲区中。
My shell history is something like: 我的shell历史是这样的:
% echo 1
% echo 2
I have found comint-dynamic-list-input-ring
which contains the commands but it's in a reverse-sorted table like this 我发现comint-dynamic-list-input-ring
包含命令,但它在这样的反向排序表中
echo2 echo1
I need a forward-sorted chronological list, ideally in a temporary buffer so I can edit the buffer and save to a .bash
file or what have you. 我需要一个按时间顺序排序的列表,最好是在一个临时缓冲区中,以便我可以编辑该缓冲区并保存到.bash
文件或您拥有的文件中。
I think you should set comint-input-ring-file-name
and use comint-write-input-ring
to save your commands: 我认为您应该设置comint-input-ring-file-name
并使用comint-write-input-ring
来保存命令:
(defun my-shell-buffers ()
"Return the list of buffers with non-nil `comint-input-ring'."
(let (ret)
(dolist (b (buffer-list) ret)
(with-current-buffer b
(when comint-input-ring
(push (buffer-name b) ret))))))
(defun my-edit-history (comint-buffer history-file)
(interactive
(list (completing-read "Comint buffer: "
(or (my-shell-buffers)
(error "No shell buffers"))
nil t nil nil
(and comint-input-ring (buffer-name)))
(read-file-name "History file name: ")))
(with-current-buffer comint-buffer
(let ((comint-input-ring-file-name history-file))
(comint-write-input-ring)
(find-file comint-input-ring-file-name))))
Thanks so much to @sds 非常感谢@sds
Just for the record, my own latest version is: 仅作记录,我自己的最新版本是:
(defun write-input-ring (filename)
"Write shell input to FILENAME then visit FILENAME."
(interactive "F")
(let ((comint-input-ring-file-name filename))
(comint-write-input-ring))
(if (file-readable-p filename)
;; If the input ring was saved to a file, visit that file
(find-file filename)
;; Else report that no input was saved
(message "This buffer has no shell history.")))
