Printing the current line in elixir source code

Question

In elixir we have the Pseudo-variables __MODULE__, __DIR__ et al. In erlang there is also the functionality to get the current line, using an erlang macro.

How do I get the current file line in elixir.

Something like

IO.puts __LINE__

Answer 1

It's all inside __ENV__:

IO.puts __ENV__.file
IO.puts __ENV__.line
