drscheme:debug:make-debug-error-display-handler in DrScheme Tools Functions
(drscheme:debug:make-debug-error-display-handler-> (string? (or/c any/c exn?) . -> . any)oedh)
oedh: (string? (or/c any/c exn?) . -> . any)This function implements an error-display-handler in terms of another error-display-handler.
This function is designed to work in conjunction with
drscheme:debug:make-debug-eval-handler.See also MzScheme's MzLinkmz:p:error-display-handlererror-display-handler parameter.
If the current-error-port is the definitions window in drscheme, this error handler inserts some debugging annotations, calls
oedh, and then highlights the source location of the runtime error.
