Overview

Filters internal Rubinius locations.

There are a couple of reasons why we wanna filter out the locations.

  • ::Kernel.raise, is implemented in Ruby for Rubinius. We don’t wanna have the frame for it to align with the CRuby and JRuby implementations.

  • For internal methods location variables can be nil. We can’t create a bindings for them.

  • Bindings from the current file are considered internal and ignored.

We do that all that so we can align the bindings with the backtraces entries.
