Overview

A wrapper class for Valkyrie logging. This class attempts to provide tooling that helps improve the communication through-out the stack.

In gem development there are several considerations regarding logging.

1) The development on the gem directly, in particular specs 2) The downstream development that leverages the gem, both when specs are

running and when running the downstream processes in a development
environment.

3) The downstream behaviors that are called in production environments.

In each of these cases, different considerations regarding logging may be relevant.

In the below example,

Examples:

Valkyrie.logger.suppress_logging_for_contexts!("A Named Context") do
  # The following will NOT be logged
  Valkyrie.logger.warn('Hello', logging_context: "A Named Context")

  # The following will be logged
  Valkyrie.logger.warn('Hello')
end
# The following will be logged
Valkyrie.logger.warn('Hello', logging_context: "A Named Context")
