Hi,
How can I access after an exception (in the rescue area) the following
information do you know (i.e. associated with where the error occured)?

- file,
- line number
- class
- method

thanks

When you catch, err, rescue exception look at the 'backtrace' method.
It won't give you all information you need, but some of them.

# file exc.rb
class A
def foo
raise "bar"
end
end

begin
a =3D A.new
a.foo
rescue =3D> e
puts e.backtrace
end

$ ruby exc.rb
exc.rb:3:in `foo'
exc.rb:9

thanks - no way to get the class name & method name then?

Method name is included in backtrace. e.backtrace returns array of
string, where each string has following form:
file:line in `method'
You can try to parse it (simply with regexp). I'm surprised that there
is no information about class but probably there is reason for that.
