Detailed Description

A spdlog formatter which wraps another formatter and makes sure that if there are new lines (\n) in the log message, that the log message is still properly indented.

Multiline log message with normal pattern formatter:

  std::shared_ptr<spdlog::logger> logger =
      spdlog::stdout_color_mt("logger_name");
  logger->set_level(spdlog::level::trace);
  SPDLOG_LOGGER_TRACE(logger, "hello\nworld");

Output:

[2020-10-08 20:45:54.021] [logger_name] [trace] [mesh_factory_tests.cc:77] hello

world

Multiline log message with LineFeedFormatter:

  std::shared_ptr<spdlog::logger> logger =
      spdlog::stdout_color_mt("logger_name");
  logger->set_formatter(std::make_unique<lf::base::LineFeedFormatter>(
      std::make_unique<spdlog::pattern_formatter>()));
  logger->set_level(spdlog::level::trace);
  SPDLOG_LOGGER_TRACE(logger, "hello\nworld");

Output:

[2020-10-08 20:47:15.781] [logger_name] [trace] [mesh_factory_tests.cc:81] hello

world
