This blog is part of our  Ruby 2.6 series.

Before Ruby 2.6, if we want to know file name with location and line number of source code, we would need to use Binding#eval (Link is not available) .

1binding.eval('[__FILE__, __LINE__]')
2=> ["/Users/taha/blog/app/controllers/application_controller", 2]

Ruby 2.6 adds more readable method Binding#source_location (Link is not available) to achieve similar result.

2=> ["/Users/taha/blog/app/controllers/application_controller", 2]

Here is relevant commit and discussion for this change.
