TextMate is a powerful text editor in Mac. This article is posted through the TextMate.
By the way, TextMate is flexible to extending its functionalities and suitable for coding. If you are looking for an excellent tool for coding (or programming) in Mac, you should try it!
不過 TextMate 目前對於 CJK 字型寬度的支援還很糟（也跟輸入法處得不好），希望它能及早改進這個 feature。（我是很勉強才打得出這些中文字的 XD）
