    "content": "Hello,\n\nThis patch series addresses a shortcoming of libcamera compared to\nGStreamer or PipeWire, namely colored logs.\n\nThis was attempted by Marco Felsch in \"[PATCH] libcamera: log: add\ncolors to log levels\" but suffered from coloring message\nunconditionally for streams, regardless of whether the stream was backed\nby a TTY, a file or something else.\n\nThis turned out impossible to solve automatically (as far as I can tell)\nas the C++ stream API doesn't expose the underlying file descriptor.\nI've thus taken another approach, by exposing coloring through the\nlibcamera logger API and only enabling it automatically when logging to\nstd::cerr. This can be disabled with the new LIBCAMERA_LOG_NO_COLOR\nenvironment variable.\n\nLaurent Pinchart (5):\n  libcamera: base: log: Remove unnecessary local variable\n  libcamera: base: log: Replace stderr with std::cerr in documentation\n  libcamera: base: log: Log to std::cerr if log file can't be opened\n  libcamera: base: log: Add coloring to the log output\n  libcamera: base: log: Color the log prefix\n\n Documentation/environment_variables.rst |  21 ++-\n include/libcamera/base/log.h            |   5 +-\n include/libcamera/logging.h             |   4 +-\n src/libcamera/base/log.cpp              | 168 +++++++++++++++++-------\n src/libcamera/camera_manager.cpp        |   2 +-\n 5 files changed, 144 insertions(+), 56 deletions(-)\n\n\nbase-commit: 3e7f54a3128d8143afb200d626d3b208d493623a"
