Displays the error message represented by the string, adding
embellishments like those that appears in the DrScheme REPL,
specifically a clickable icon for the stack trace (if the srcloc location is not empty),
and a clickable icon for the source of the error (read & syntax errors show their source
locations and otherwise the first place in the stack trace is shown).
If stack is false, then the stack trace embedded in the exn argument (if any) is used.
This should be called in the same eventspace and on the same thread as the error.

| 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 error-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.
This function implements an eval-handler in terms of another
eval-handler.
This function is designed to work in conjunction with drscheme:debug:make-debug-error-display-handler.
See also MzScheme’s eval-handler parameter.
The resulting eval-handler expands and annotates the input
expression and then passes it to the input eval-handler,
unless the input expression is already compiled, in which
case it just hands it directly to the input eval-handler.
Hides the backtrace window.
| (drscheme:debug:profiling-enabled enabled?) → void? |
| enabled? : boolean? |
| (drscheme:debug:profiling-enabled) → boolean? |
A parameter that controls if profiling information is recorded.
Defaults to #f.
Only applies if
drscheme:debug:make-debug-eval-handler
has been added to the eval handler.
Adds the profiling preferences panel.
| (drscheme:debug:open-and-highlight-in-file debug-info) → void? |
| debug-info : (or/c srcloc? (listof srcloc?)) |
This function opens a DrScheme to display
debug-info. Only the src the position
and the span fields of the srcloc are considered.
See also
drscheme:debug:get-cm-key.

| error-message : string? | ||||||||||||||
| dis : (or/c exn? (listof srcloc?)) |
Shows the backtrace window you get when clicking on the bug in
DrScheme’s REPL.
The error-message argument is the text of the error,
dis is the debug information, extracted from the
continuation mark in the exception record, using
drscheme:debug:get-cm-key.
Returns a key used with contination-mark-set->list.
The contination mark set attached to an exception record
for the user’s program may use this mark. If it does,
each mark on the continuation is a list of the fields
of a srcloc object.
