This kind of support makes this text editor an option for developers. The list of supported languages is decent. I was quite surprised to see that it can highlight the syntax even though I saved the file as '.txt'. The normal text editing is quite irrelevant because even the built-in TextEdit can do a fair job. Since it is a text editor, the first thing that I checked was the syntax highlighting for specific languages. It is fast, it has a well designed interface, and a very good support for various programming languages. Indeed, TextMate is a pretty good text editor. TextMate is referred as the missing text editor on Mac OS X.
