在Mac中用快捷键快速插入日期时间
在Windows中有AutoHotkey这个好东东帮我快速插入日期时间，输入[mm然后敲空格就可以了。在Mac中就没有这么好的事了，虽然能够实现，但是没有AutoHotkey方便。还是要借助于AppleScript，但是并不能适用于Mac中任何文本输入的地方，比如DayOne的弹出窗口就不能用，另外还有一个限制：只能对选中的文字进行操作。
我使用的是这个文章里面的方案：
http://www.sixhat.net/applescript-insert-date-and-time-into-your-documents.html
代码是：
-- Insert Date and Time into your documents
-- @2012 David Rodrigues
set date_ to ((current date) as string)
set the clipboard to the date_
tell application "System Events"
set frontmostApplication to name of the first process whose frontmost is true
end tell
tell application frontmostApplication
activate
tell application "System Events"
keystroke "v" using {command down}
end tell
end tell
注意它会改变粘贴板的内容。我为它定义了一个快捷键：Cmd+Alt+Shift+F。使用之前，可以先敲一个字母，然后选中字母，按这个快捷键，就会显示出来日期时间了。比如现在的时间是： 2014-12-22 19:39:03 +0800。
下面的英文描述是下面参考第一个链接文章的内容，有时间再翻译。
Below is a very simple AppleScript that inserts the date, time and timezone in the format that Jekyll requires.
do shell script "date +%Y-%m-%d\\ %H:%M:%S\\ %z"
To make inserting it simple, it’s possible to assign a keyboard shortcut, by turning it into a Service in Automator.
Open Automator.app
Create a new Service
Set it to receive selected text in any application
Check the ‘Output replaces selected text’ tick-box
Insert the ‘Run AppleScript’ action
Copy and paste the above AppleScript
Press run to make sure it works
Save the
.workflowfile to~/Library/ServicesOpen the
Keyboard > Keyboard Shortcutssystem preference pane, select Services in the left column, then find the Service you just created.Assign a keyboard shortcut. I use
Command+Option+d
There is one pitfall: it only works on selected text.
When saving a post for Jekyll, the file-name also requires a date—but not a time. For this, you can follow the same process as above with a modified AppleScript:
do shell script "date +%Y-%m-%d"
For this, I use the keyboard shortcut Command + Option + Shift + d.
I would love it if the Service created the entire file name. So if the post title ‘This is a Post Title’ was on the clipboard, it would create a file called 2012-11-10-this-is-a-post-title.md; replacing spaces with hyphens and converting it to lowercase. However, that’s well beyond my very limited AppleScript knowledge.
