A common issue I have is that the default error handler does not display error message's exn:srcloc if it has it
racket -e "(require racket/match)" -e "(match 2)" => match: no matching clause for 2 context...: /Users/endobson/proj/rnacket/plt/racket/collects/racket/match/runtime.rkt:21:0: match:error But no information about what match raised the issue. The handler in DrRacket uses this info nicely in the buttons that it provides and the highlighting. Is this reasonable to add to the default error handler, and if so do people have suggestions on the format? My current .racketrc has (let ((old-error-display-handler (error-display-handler))) (error-display-handler (λ (str exn) (when (exn:srclocs? exn) (for ((srcloc ((exn:srclocs-accessor exn) exn))) (displayln (source-location->string srcloc)))) (old-error-display-handler str exn))))) Which is a hack but works for my interactive use. It doesn't work for when I run a program on its own, and I don't see a way to configure anything to do that. _________________________ Racket Developers list: http://lists.racket-lang.org/dev
