But keep a namespace alias to avoid breaking project that depend on the previous namespace name while they get updated. Done with through the following steps: - git grep -l dawn_native:: | xargs sed -i "" "s/dawn_native::/dawn::native::/g" - git grep -l "namespace dawn_native" | xargs sed -i "" "s/namespace dawn_native/namespace dawn::native/g" - git cl format - Manual fixups in generator/templates (and the addition of namespace_case in dawn_json_generator.py). - The addition of the namespace alias in DawnNative.h Bug: dawn:824 Change-Id: I676cc4e3ced2e0e4bab32a0d66d7eaf9537e3f09 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/75982 Reviewed-by: Loko Kung <lokokung@google.com> Commit-Queue: Corentin Wallez <cwallez@chromium.org> Auto-Submit: Corentin Wallez <cwallez@chromium.org>
