The stdio_logger extension exposes a Sequel::StdioLogger class that can be used for logging with Sequel, as a minimal alternative to the logger library. It exposes debug/info/warn/error methods for the different warning levels. The debug method is a no-op, so that setting the Database sql_log_level to debug will result in no output for normal queries. The info/warn/error methods log the current time, log level, and the given message.
To use this extension:
Sequel.extension :stdio_logger
Then you you can use Sequel::StdioLogger to wrap IO objects that you would like Sequel to log to:
DB.loggers << Sequel::StdioLogger.new($stdout) log_file = File.open("db_queries.log", 'a') log_file.sync = true DB.loggers << Sequel::StdioLogger.new(log_file)
This is implemented as a global extension instead of a Database extension because Database loggers must be set before Database extensions are loaded.
