[Wtr-general] A small doubt in exception handling

[vijay]

Hello people,

Is there a way in Watir by which one can capture the line number of the code that threw an exception?  We can get the actual message in the exception from the gloabl variable '$!'.  Can we get the code's line number, which caused this exception, from some other global variable?

For example, the following code:

begin
	print z
rescue
	puts "The exception message was " + $!.to_s
end

would output the message, 

'The exception message was undefined local variable or method `z' for #<Object:0x2ac9258>'.  

But without the 'begin -- rescue class;, the code would have printed the error message, 

'file_name.rb:117 (or some other line number): undefined local variable or method `z' for #<Object:0x2ac9258> (NameError)

I want to use the 'begin -- rescue class' and still get the exact line number along with the error message.  Is that possible?

Thanks for your time,
Vijay.
