Overview

Deprecated.

This class is deprecated and will be removed in version 0.2.0. Use Makit::Logging::Logger with multiple middleware instead.

Multi-target logger that writes to multiple destinations

This logger allows writing log messages to multiple targets simultaneously, such as both stdout and a file, or multiple files with different formats.

Examples:

Create a logger that writes to both console and file

stdout_logger = Logger.new($stdout)
file_logger = Logger.new("app.log")
multi_logger = MultiLogger.new(stdout_logger, file_logger)
multi_logger.info("This goes to both destinations")

Constructor Details

#initialize(*targets) ⇒ MultiLogger

Initialize a new MultiLogger with multiple logging targets

Parameters:

  • targets (Array<Logger>) —

    One or more logger instances to write to

  @targets = targets
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method) ⇒ nil

Forward any unknown methods to all logger targets

This allows calling standard Logger methods like info, debug, error, etc. directly on the MultiLogger instance.

Parameters:

  • method (Symbol) —

    The method name to forward

  • args (Array) —

    Arguments to pass to the method

Returns:

  • (nil)

  @targets.each { |logger| logger.send(method, ...) }
end

Class Method Details

.create_file_logger(log_filename, log_level, options) ⇒ Logger

Create a file logger with appropriate formatter

Creates a logger that writes to a file with the specified formatter and log level. Ensures the directory for the log file exists.

Parameters:

  • log_filename (String) —

    Path where log file should be created

  • log_level (Integer) —

    Log level to set (from Logger constants)

  • options (Hash) —

    Configuration options

Options Hash (options):

  • :structured_logging (Boolean) — default: false —

    Whether to use JSON formatted logs

Returns:

  • (Logger) —

    Configured file logger

  file_logger = ::Logger.new(log_filename)
  file_logger.level = log_level

  # Use structured logging for file output if requested

  file_logger.formatter = if options[:structured_logging]
      StructuredFormatter.new
    else
      PlainFormatter.new
    end

  file_logger
end

.create_log_filename(options) ⇒ String

Determine the appropriate log filename

Generates a log filename based on options and the current rake task. If a custom log file is specified in options, that is used. Otherwise, a log file is created in the artifacts directory with a name based on the current rake task.

Parameters:

  • options (Hash) —

    Configuration options

Options Hash (options):

  • :log_file (String) — default: nil —

    Custom log file path

Returns:

  • (String) —

    The path to use for the log file

.create_logger(options = {}) ⇒ Logger, MultiLogger

Deprecated.

This method is deprecated and will be removed in version 0.2.0. Use Makit::Logging::Logger.new with middleware instead.

Create a configured logger based on options

This factory method creates a logger configured with appropriate formatters and targets based on the provided options. By default, it creates a logger that writes to both stdout (with colors) and a log file (plain text).

Parameters:

  • options (Hash) (defaults to: {}) —

    Logger configuration options

Options Hash (options):

  • :level (Symbol) — default: :info —

    The log level (:debug, :info, :warn, :error, :fatal)

  • :file_logging (Boolean) — default: true —

    Whether to log to a file

  • :log_file (String) — default: nil —

    Custom log file path, defaults to rake task-based path

  • :structured_logging (Boolean) — default: false —

    Whether to use JSON structured logging for file output

Returns:
