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。
