end

StackTrace.current # => Returns a Hash that contains all the method calls and exception information.

Configuration

StackTrace.configure do |config|
  config.trace_ruby = true
  config.trace_c = true
  config.inspect_return_values = true # Default `false` for performance reasons
  config.inspect_arguments = true # Default `false` for performance reasons

  config.check_proc = -> (self_klass_name, defined_klass_name, method_name) do # If you want to limit the tracing for a set of classes
    self_klass_name == "Bar"

    # If you use autoload and resolve the constant by klass names
    # it's really likelly that you get a segfault: https://bugs.ruby-lang.org/issues/18120.
    # Preload all the constants before running the `StackTrace.trace` if you want to
    # constantize klass names.
  end
