を見て。
pythonもplugin作るのも初めてなんで不具合とかあるかもです(><)
何かあったら誰か直してください(><)

#ソース

SuddenDeath.py

# -*- coding: utf-8 -*-

import sublime, sublime_plugin

class SuddenDeathCommand(sublime_plugin.TextCommand):
	def width_kana(self,str):
		all = len(str)              # 全文字数
		zenkaku = self.count_zen(str)    # 全角文字数
		hankaku = all - zenkaku     # 半角文字数
		return zenkaku * 2 + hankaku
	def count_zen(self,str):
		from unicodedata import east_asian_width
		n = 0
		for c in str:
			wide_chars = u"WFA"
			eaw = east_asian_width(c)
			if wide_chars.find(eaw) > -1:
				n += 1
		return n
	def run(self, edit):
		for region in self.view.sel():
			if not region.empty():
				strs=self.view.substr(region).splitlines()
				max_width=max(map(self.width_kana,strs))
				head=u"＿人"+u"人"*(max_width/2)+u"人＿\n"
				tail=u"￣Ｙ"+u"Ｙ"*(max_width/2)+u"Ｙ￣\n"
				death_str=head
				for str in strs:
					death_str+=u'＞　%s　＜\n' % (str+" "*(max_width - self.width_kana(str)))
				death_str+=tail
				self.view.replace(edit, region, death_str)

#使い方
~/.config/sublime-text-2/Packages/Userに保存。
適当にキーバインドして囲みたい文字を選択して実行。
