存放在：…\Sublime Text\Data\Packages\User\Default 下
Sublime 自帶的 snippet 只是 XML 的文字，如果想同時使用自定義變數沒辦法了。（起碼我沒辦法）
來自己寫個插入作者資訊的命令放在主選單、熱鍵

選單檔案：Main.sublime-menu

[
  { "command": "save", "caption": "儲存 (S)" },
  { "command": "build", "caption": "編譯 (B)" , "mnemonic": "B" ,"id":"build"},
  {
    "caption": "自定義(J)",
    "mnemonic": "J",
    "id": "CustomizeMenus",
    "children":
    [
        { "command": "add_author_info", "caption": "插入作者", "id":"insertAuthor"},
        { "command": "add_current_date", "caption": "插入日期", "id":"insertDate"},
        { "command": "add_current_time", "caption": "插入時間", "id":"insertTime"},
        { 
        	"caption": "計算器", 
        	"command": "exec", 
        	"args": {
        		"cmd": ["calc.exe","引數1","引數2"]
        	}
        },
        { "caption": "-" },
        { "command": "open_url", "args": {"url": "http://blog.csdn.net/jx520"}, "caption": "湖邊的小屋遺址" }

    ]
}
]
 

存放在 …\Sublime Text\Data\Packages 下即可，我就在這裡建立了個資料夾，放自己寫的外掛。
檔名不限，但要注意類名和呼叫命令的關係

${5}""" %datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
            }
        )
## 插入日期
# class AddCurrentDateCommand(sublime_plugin.TextCommand):
# class add_current_dateCommand(sublime_plugin.TextCommand):
# 個人覺得能與命令呼叫時保持一致是滿不錯的選擇
class add_current_date(sublime_plugin.TextCommand):
    def run(self, edit):
        self.view.run_command("insert_snippet",
            {
                "contents": "%s" % datetime.datetime.now().strftime("%Y-%m-%d ")
            }
        )
## 插入時間
class add_current_time(sublime_plugin.TextCommand):
    def run(self, edit):
        self.view.run_command("insert_snippet",
            {
                "contents": "%s" % datetime.datetime.now().strftime("%H:%M:%S")
            }
