Ruby 2.6 adds Binding#source_location

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 .

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

Ruby 2.6 adds more readable method Binding#source_location to achieve similar result.

1binding.source_location
2=> ["/Users/taha/blog/app/controllers/application_controller", 2]
Copy

Here is relevant commit and discussion for this change.
