I have a code that looks quite like:
ignore
(f ())
handle
AssertionError msg => (print ("assertion error: " ^ msg ^ "\n"); ())
| _ (* other exceptions *) => (print ("exception raised\n"); ())
But I need to print the generic exception message (with exnMessage
?).
How do I catch the _
exception in order to get and print its message?
Match the exception with a name instead of _
and use exnMessage
:
- (hd ([]: string list)) handle e => exnMessage e;
val it = "Empty" : string
