What started as a single patch is now a series that\n\n- Replaces map iterators and pairs with structured bindings (1/4)\n- Replaces iterators for non-associative containers (vector, span, ...)\n with range-based for loops (2/4)\n- Rename one occurrence of a variable named 'it' that does not refer to\n an iterator (3/4)\n- Standardize on 'const auto' instead of 'auto const'\n\nOne thing *not* addressed by this series is replacement of 'auto' with\n'const auto' or 'const auto &' where applicable. This could be done on\ntop by someone with enough motivation :-)\n\nLaurent Pinchart (4):\n libcamera: Replace iterators with structured bindings\n libcamera: Replace iterators with range-based for loops\n libcamera: Use `it` variable name for iterators only\n libcamera: Standardize on 'const auto'\n\n .../guides/application-developer.rst | 2 +-\n include/libcamera/base/utils.h | 10 ++--\n .../libcamera/internal/ipa_data_serializer.h | 10 ++--\n src/apps/common/options.cpp | 6 +--\n src/apps/common/stream_options.cpp | 4 +-\n src/gstreamer/gstlibcamera-controls.cpp.in | 7 +--\n src/gstreamer/gstlibcamera-utils.cpp | 50 ++++++++-----------\n src/ipa/ipu3/ipu3.cpp | 8 +--\n src/ipa/mali-c55/mali-c55.cpp | 8 +--\n src/ipa/rkisp1/rkisp1.cpp | 8 +--\n src/ipa/rpi/common/ipa_base.cpp | 4 +-\n src/ipa/rpi/controller/controller.cpp | 6 +--\n src/ipa/rpi/controller/rpi/agc.cpp | 4 +-\n src/ipa/rpi/controller/rpi/agc_channel.cpp | 2 +-\n src/ipa/rpi/controller/rpi/lux.cpp | 2 +-\n src/ipa/rpi/pisp/pisp.cpp | 2 +-\n src/ipa/rpi/vc4/vc4.cpp | 2 +-\n src/ipa/simple/soft_simple.cpp | 8 +--\n src/libcamera/camera.cpp | 4 +-\n .../converter/converter_v4l2_m2m.cpp | 8 +--\n src/libcamera/delayed_controls.cpp | 4 +-\n src/libcamera/media_device.cpp | 2 +-\n src/libcamera/pipeline/ipu3/cio2.cpp | 6 +--\n src/libcamera/pipeline/ipu3/ipu3.cpp | 11 ++--\n src/libcamera/pipeline/mali-c55/mali-c55.cpp | 2 +-\n .../pipeline/rpi/common/delayed_controls.cpp | 4 +-\n .../pipeline/rpi/common/pipeline_base.cpp | 29 ++++++-----\n .../pipeline/rpi/common/rpi_stream.cpp | 8 +--\n src/libcamera/pipeline/rpi/pisp/pisp.cpp | 6 +--\n src/libcamera/pipeline/rpi/vc4/vc4.cpp | 2 +-\n src/libcamera/pipeline/vimc/vimc.cpp | 10 ++--\n src/libcamera/pipeline/virtual/virtual.cpp | 2 +-\n src/libcamera/request.cpp | 3 +-\n src/libcamera/sensor/camera_sensor_legacy.cpp | 4 +-\n src/libcamera/sensor/camera_sensor_raw.cpp | 4 +-\n src/libcamera/software_isp/software_isp.cpp | 3 +-\n src/libcamera/stream.cpp | 8 +--\n src/libcamera/v4l2_videodevice.cpp | 8 ++-\n test/media_device/media_device_print_test.cpp | 10 ++--\n test/v4l2_videodevice/buffer_cache.cpp | 2 +-\n 40 files changed, 126 insertions(+), 157 deletions(-)\n\n\nbase-commit: da12b1854fbc0ec32d3162a0ab97654fcb679ae3"}
