.clang-tidy

---
#
# Clang-Tidy configuration for simSYCL.
#
# There are three usage scenarios:
# 1. Automatic checks through an IDE (CLion, VsCode, ...)
# 2. Running manually on select files (not recommended)
#    `clang-tidy -p path/to/compile_commands.json file1 [file2, ...]`
#    Note: A script for running clang-tidy on all Celerity sources is provided in `ci/run-clang-tidy.sh`
# 3. Running on a diff (for CI)
#    `git diff -U0 --no-color | clang-tidy-diff.py -p1 -path path/to/compile_commands.json`
#
InheritParentConfig: false
# See https://clang.llvm.org/extra/clang-tidy/checks/list.html for a full list of available checks.
# Note: We would like to enable `misc-const-correctness` (introduced with Clang 15), but it currently
#       seems to be somewhat buggy still (producing false positives) => revisit at some point.
