Changelog

Sourced from flexi_logger's changelog.

[0.18.0] - 2021-06-02

Significant API revision, to better cope with new features and for better readability/applicability. Most important changes:

• Better error handling in factory methods:
  • Logger::with_env() is replaced with Logger::try_with_env(), which returns a Result
  • Logger::with_str() is replaced with Logger::try_with_str(), which returns a Result
  • Logger::with_env_or_str() is replaced with Logger::try_with_env_or_str(), which returns a Result
  • consequently, the method Logger::check_parser_error is gone
• Bundling file-related aspects
  • introduction of FileSpec
  • move of filename-related methods from Logger to FileSpec (and similarly on the FileLogWriter)
• Logger::log_target(LogTarget) is replaced with a set of methods
  • Logger::log_to_file(FileSpec)
  • Logger::log_to_stdout()
  • Logger::log_to_stderr()
  • Logger::log_to_writer(FileSpec)
  • Logger::log_to_file_and_writer(FileSpec,Box<dyn LogWriter>)
  • Logger::do_not_log()
• The new method Logger::write_mode(WriteMode)
  • replaces several methods to control buffer handling etc
  • offers additionally asynchronous file I/O (if the crate feature async is used)
• Keeping the LoggerHandle alive has become crucial (except for trivial cases)!
• Several methods are now more generic with their input parameters
• A new method LoggerHandle::reset_flw allows reconfiguring a used FileLogWriter at runtime

Added an option to apply a stateful filter before log lines are really written (kudos to jesdazrez (Jesús Trinidad Díaz Ramírez)).

Fixed error handling in logspec parsing (wrong error was thrown).

Several docu improvements.

[0.17.1] - 2021-01-14

Add options Logger::buffer_and_flush() and buffer_and_flush_with() as means to avoid long output delays.

[0.17.0] - 2021-01-08

Introduce optional buffering of log output. This increases performance (which can be relevant for programs with really high log production), but delays log line appearance in the output, which can be confusing, and requires to flush or shutdown the logger at the end of the program to ensure that all logs are written to the output before
