TextMate is Love
Just another reason I love TextMate and the users who use it with me: odds are, if you’re trying to solve a specific problem or configure things just so with the editor, someone else has all ready done it. Start searching Google with site:lists.macromates.com instead of re-inventing the wheel.
I had wanted PHP and HTML syntax editing all within the same files, since a lot of my use at work (and my original reason to buy TextMate) was for PHP and XHTML web development. And, as I suspected, there was a fix for exactly what I was trying to solve: set the syntax highlighting to HTML, and it sees the PHP environment automagically.
