Logging and user interaction - HebaruSan/CKAN GitHub Wiki

The CKAN core is intended to be reusable across multiple clients, including consoles, native and web-based GUIs, and batch processes.

• Use User.WriteLine() rather than Console.WriteLine(). You should only use Console.WriteLine() if you know there is going to be a console.
• Use log4net generously:
  • log.Debug() for matters that will of only be interest to developers (--debug), and log.Info() for matters that users may find interesting when running with --verbose. Note that --debug implies --verbose.
  • log.Warn(), log.Error() and log.Fatal() will always be logged.
  • All log4net functions come with formatted versions. Eg: log.DebugFormat() or log.WarnFormat().
