This is\ndone in patch 4/5. As a byproduct, I ended up simplifying the generation\nby merging the two scripts into one (2/5) and moving the build logic\n(1/5) and generation script (3/5) to the right location.\n\nThe last patch (5/5) is an API improvement for the eGL class that\nresults from a suggestion received in the review of v1.\n\n\nLaurent Pinchart (5):\n libcamera: shaders: Move header generation to shaders directory\n utils: Merge shader header generation scripts\n utils: Rename and move shader header generation script\n libcamera: shaders: Replace C array with std::array\n libcamera: egl: Replace pointer and length with span for shader\n sources\n\n include/libcamera/internal/egl.h | 9 +--\n src/libcamera/egl.cpp | 29 ++++-----\n src/libcamera/meson.build | 10 ---\n src/libcamera/shaders/meson.build | 10 +++\n src/libcamera/software_isp/debayer_egl.cpp | 25 +++-----\n utils/codegen/gen-shader-header.py | 74 ++++++++++++++++++++++\n utils/codegen/meson.build | 1 +\n utils/gen-shader-header.py | 37 -----------\n utils/gen-shader-headers.sh | 54 ----------------\n utils/meson.build | 2 -\n 10 files changed, 109 insertions(+), 142 deletions(-)\n create mode 100755 utils/codegen/gen-shader-header.py\n delete mode 100755 utils/gen-shader-header.py\n delete mode 100755 utils/gen-shader-headers.sh\n\n\nbase-commit: 7a033dbdd4ca29cca2ef7eb144f6a6f57979b70d" }
