Code.eval_file

You're seeing just the function eval_file, go back to Code module for more information.

eval_file(file, relative_to \\ nil)

eval_file(binary(), nil | binary()) :: {term(), binding()}

Evals the given file.

Accepts relative_to as an argument to tell where the file is located.

While require_file/2 and compile_file/2 return the loaded modules and their bytecode, eval_file/2 simply evaluates the file contents and returns the evaluation result and its binding (exactly the same return value as eval_string/3).
