Overview

Calculate the path under ‘output_path` that has the same structure relative to one of the `base_paths`

“‘rb calculator = PathCalculator.new(Pathname(“/rbs-inline”), [Pathname(“app”), Pathname(“lib”)], Pathname(“/tmp/sig”)) calculator.calculate(Pathname(“/rbs-inline/app/models/foo.rb”)) # => Pathname(“/tmp/sig/models/foo.rb”) calculator.calculate(Pathname(“/rbs-inline/lib/bar.rb”)) # => Pathname(“/tmp/sig/bar.rb”) calculator.calculate(Pathname(“/rbs-inline/hello/world.rb”)) # => Pathname(“/tmp/sig/hello/world.rb”) calculator.calculate(Pathname(“/foo.rb”)) # => nil “`
