我可以使用Emacs中的哪些命令将当前日期和时间插入文件的文本缓冲区?
(例如,Notepad中的等效功能是简单地按F5,这大约是Notepad唯一有用的功能!)
C-u M-! date
放入.emacs文件:
;; ====================
;; insert date and time
(defvar current-date-time-format "%a %b %d %H:%M:%S %Z %Y"
"Format of date to insert with `insert-current-date-time' func
See help of `format-time-string' for possible replacements")
(defvar current-time-format "%a %H:%M:%S"
"Format of date to insert with `insert-current-time' func.
Note the weekly scope of the command's precision.")
(defun insert-current-date-time ()
"insert the current date and time into current buffer.
Uses `current-date-time-format' for the formatting the date/time."
(interactive)
(insert "==========n")
; (insert (let () (comment-start)))
(insert (format-time-string current-date-time-format (current-time)))
(insert "n")
)
(defun insert-current-time ()
"insert the current time (1-week scope) into the current buffer."
(interactive)
(insert (format-time-string current-time-format (current-time)))
(insert "n")
)
(global-set-key "C-cC-d" 'insert-current-date-time)
(global-set-key "C-cC-t" 'insert-current-time)
参考
我用过这些简短的片段:
(defun now ()
"Insert string for the current time formatted like '2:34 PM'."
(interactive) ; permit invocation in minibuffer
(insert (format-time-string "%D %-I:%M %p")))
(defun today ()
"Insert string for today's date nicely formatted in American style,
e.g. Sunday, September 17, 2000."
(interactive) ; permit invocation in minibuffer
(insert (format-time-string "%A, %B %e, %Y")))
它们最初来自journal.el
插入日期:
M-x org-time-stamp
插入日期时间:
C-u M-x org-time-stamp
您可以为该命令绑定全局密钥。
org-mode
的方法非常用户友好,您可以从日历中选择任何日期。
您可以安装yasnippet,它将允许您键入"时间"和tab键,除此之外,还可以执行更多操作。它只是在后台调用current-time-string
,因此您可以使用format-time-string
控制格式设置。
这是我不久前写的一个包,它可以满足您的要求。
http://github.com/rmm5t/insert-time.el/tree/master/insert-time.el
(require 'insert-time)
(define-key global-map [(control c)(d)] 'insert-date-time)
(define-key global-map [(control c)(control v)(d)] 'insert-personal-time-stamp)
M-1M-!日期
这将导致您运行的shell命令插入到当前正在编辑的缓冲区中,而不是插入到新的缓冲区。
最简单的方法可能是:
(插入(当前时间字符串))
插入日期:
C-c . RET
对于选择日期向左/向右/向上/向下移位-RET(输入)
谢谢,CMS!我的变体,就其价值而言,让我足够高兴:
(defvar bjk-timestamp-format "%Y-%m-%d %H:%M"
"Format of date to insert with `bjk-timestamp' function
%Y-%m-%d %H:%M will produce something of the form YYYY-MM-DD HH:MM
Do C-h f on `format-time-string' for more info")
(defun bjk-timestamp ()
"Insert a timestamp at the current point.
Note no attempt to go to beginning of line and no added carriage return.
Uses `bjk-timestamp-format' for formatting the date/time."
(interactive)
(insert (format-time-string bjk-timestamp-format (current-time)))
)
我把它放在一个文件中,该文件由我的.emacs使用:调用
(load "c:/bjk/elisp/bjk-timestamp.el")
这既使修改变得更容易,又不必冒破坏.emacs中其他内容的风险,还让我有一个简单的切入点,也许有一天我会真正了解emacs Lisp编程的全部内容。
附言:非常欢迎对我n00b技术的批评。
这是我的看法。
(defun modi/insert-time-stamp (option)
"Insert date, time, user name - DWIM.
If the point is NOT in a comment/string, the time stamp is inserted prefixed
with `comment-start' characters.
If the point is IN a comment/string, the time stamp is inserted without the
`comment-start' characters. If the time stamp is not being inserted immediately
after the `comment-start' characters (followed by optional space),
the time stamp is inserted with “--” prefix.
If the buffer is in a major mode where `comment-start' var is nil, no prefix is
added regardless.
Additional control:
C-u -> Only `comment-start'/`--' prefixes are NOT inserted
C-u C-u -> Only user name is NOT inserted
C-u C-u C-u -> Both prefix and user name are not inserted."
(interactive "P")
(let ((current-date-time-format "%a %b %d %H:%M:%S %Z %Y"))
;; Insert a space if there is no space to the left of the current point
;; and it's not at the beginning of a line
(when (and (not (looking-back "^ *"))
(not (looking-back " ")))
(insert " "))
;; Insert prefix only if `comment-start' is defined for the major mode
(when (stringp comment-start)
(if (or (nth 3 (syntax-ppss)) ; string
(nth 4 (syntax-ppss))) ; comment
;; If the point is already in a comment/string
(progn
;; If the point is not immediately after `comment-start' chars
;; (followed by optional space)
(when (and (not (or (equal option '(4)) ; C-u or C-u C-u C-u
(equal option '(64))))
(not (looking-back (concat comment-start " *")))
(not (looking-back "^ *")))
(insert "--")))
;; If the point is NOT in a comment
(progn
(when (not (or (equal option '(4)) ; C-u or C-u C-u C-u
(equal option '(64))))
(insert comment-start)))))
;; Insert a space if there is no space to the left of the current point
;; and it's not at the beginning of a line
(when (and (not (looking-back "^ *"))
(not (looking-back " ")))
(insert " "))
(insert (format-time-string current-date-time-format (current-time)))
(when (not (equal option '(16))) ; C-u C-u
(insert (concat " - " (getenv "USER"))))
;; Insert a space after the time stamp if not at the end of the line
(when (not (looking-at " *$"))
(insert " "))))
我更喜欢将其绑定到C-c d
。
当我想用一种简单的方法插入当前日期和时间时,这篇文章就出现了。但没有一个答案显示了插入时间的最简单方法。然后,我又进行了一番搜索,找到了答案。。。
C-u C-C。插入具有当前日期和时间的活动时间戳。
C-u C-C!插入带有当前日期和时间的非活动时间戳。
正如Misho发布的那样,省略C-u只是日期,没有时间。
这没有副作用折衷主义的答案。
