A few ideas here: 1. Geiser mode for Emacs provides both of these things. 2. The general way to go about this would be to use `identifier-binding` to find the module(s) that define and provide the thing, then search within the file to find the definition or provision. A head start: https://github.com/greghendershott/racket-mode/blob/master/defn.rkt 3. Another approach, as Neil mentioned, is to provide this capability at least for functions you define yourself. Starter using a struct with a procedure property (you could also use a side dictionary for this): http://stackoverflow.com/questions/20349543/how-do-you-return-the-description-of-a-procedure-in-scheme/20362858#20362858 As Neil mentioned you could create a #lang where `define` is your special define of this sort. ____________________ Racket Users list: http://lists.racket-lang.org/users
