Okay. > It sounds like DrRacket is handling a `#f` result ok: it should only > support syntax coloring if a language specifies a 'color-lexer > configuration via `get-info`, and so if `get-info` is not provided, > then no 'color-lexer configuration is available. Or is `get-info` > provided and somehow not recognized? Syntax coloring is one thing and that's what's turning things red, yes. But I think that a language that defines a get-info that returns the default value for color-lexer should get the same behavior as when read-language returns #f. The former currently gets the racket-lexer. Do you think that behavior should change? (DrRacket also consults the read-language returned get-info procedure for other things, including the lack of buttons that Matthew B. reported. As it happens, the "returns #f" path is currently going thru the "raises exn" path, which is probably not what we want.)
