Who knows how to add indentation rules to DrRacket? Where are they found? Is their modification something that can be attempted by a long-time programmer, but Racket novice? If I can add an indentation rule for "if" that just duplicates the current default behavior, then hopefully, it would highlight my ifs! > The specific conditional that you might be looking (if you wish to do things > differently) for is in framework/private/racket.rkt around line 1306 in the > body of racket-lexer-wrapper.

I don't really want to add a new preference pane to DrRacket; that sounds like a useful and worthy project for someone with more time and experience than I have. I just want to get DrRacket to highlight "if" to start out with. Any other knowledgable people willing to share some insights to help in this quest? --Christopher > > Robby > > > On Sat, Jun 8, 2013 at 2:05 PM, Christopher <ultimatemacfana...@gmail.com> > wrote: > Greetings all!
