Overview

Snp::Printer

This class is responsible for outputing string in normal output and error streams. It defaults to ‘STDOUT` and `STDERR`, respectively but can be used to generate output for other streams.

Example

stream = Snp::Printer.new
stream.out('Hello')  # => 'Hello' is written to the standard output
stream.err('ERROR!') # => 'ERROR!' is written to the standard error
