How can I see which exception was raised in the rescue block in this method?

method_with_rescue_block.rb

def some_method

  # some stuff in ruby that might fail

  rescue

  # do stuff, like drop into pry, with binding.pry, or ruby-debug with debugger to inspect 
  # state for debugging

end

def divide_thousand_by_number(n)
1000 / n
rescue => error
puts error.class
end

divide_thousand_by_number(1)
=> 1000
divide_thousand_by_number(0)
=> ZeroDivisionError

Ah, thanks Andrew,

I didn't know about the => error part inside a method. That's exactly what I was looking for !

BTW, I came across this when asking in #rubylang on freenode.net

Handy huh?

You always have access to the last exception thrown in the variable $! as well.

But in regards to the => error, be careful with this, blanket catching exceptions isn't a great idea. Add more specific rescue clauses with the exception types, for example:

rescue ZeroDivisionError => e
handle_divide_by_zero
