Uh, actually, I completely forgot about that macro... That actually *can* be handled in a line-based fashion, because TextMate operates by opening "scopes" in response to patterns. Thanks for picking up on that! *And why \\fB inside a .de is treated as \fB.* That was actually a conscious exception on my part. Many roff macros need heavy escaping, so I made all `\` characters match as one character. For syntax themes that recognise punctuation characters, this can have a huge improvement to readability: [image: Inline images 1] So the expected result of \fB inside a `.de` block would, of course, be that the text inside is emboldened. *Why is .PS orange versus .PE's purple?* Hrm, could you show me where you're seeing that, please? =) BTW, I'm still finishing off some rough edges - specifically, adding highlighting for Pic and other preprocessors.
