Catching line numbers in ruby exceptions

Question

Consider the following ruby code

test.rb:

begin

  puts
  thisFunctionDoesNotExist
  x = 1+1
rescue Exception => e
  p e
end

For deb

Answer 1

Usually the backtrace contains a lot of lines from external gems It's much more convenient to see only lines related to the project itself

My suggestion is to filter the backtrace by the project folder name

puts e.backtrace.select { |x| x.match(/HERE-IS-YOUR-PROJECT-FOLDER-NAME/) }

And then you can parse filtered lines to extract line numbers as suggested in other answers.
