# The approach for using clang tidy is to enable all warnings unless it adds no practical value to the CharLS projects
|
|
# Having all warnings enables helps to find problems when new code is added to the project. Some warnings are however
|
|
# to noisy and adding NO_LINT suppressions make the code less readable.

# -llvm-header-guard => Rationale: #pragma once is used
|
|
# -hicpp-no-array-decay => Rationale: alias for cppcoreguidelines-pro-bounds-constant-array-index
|
|
# -hicpp-signed-bitwise => Rationale: Bad test, types are checked, not values.
|
|
# -clang-diagnostic-c++98-compat* => Rationale: CharLS targets C++17

|
|
# -clang-diagnostic-sign-conversion => Rationale: warning will be enabled in additional steps
|
|
# -clang-diagnostic-switch-enum => Rationale: options are handled by default case
|
|
# -clang-diagnostic-exit-time-destructors => Rationale: Acceptable construction
|
|
# -clang-diagnostic-pragma-once-outside-header => Rationale: Generates false warnings for usage in header files
|
|
# -clang-diagnostic-unused-const-variable => Rationale: false warnings for constexpr in .h files
|
|
# -clang-diagnostic-unused-command-line-argument => Rationale: false warning about option passed to MSVC
|

# -clang-diagnostic-declaration-after-statement => Rationale: Target is C17 and higher
|
|
# -clang-diagnostic-unsafe-buffer-usage => Rationale: Too many false warnings, access is verified with other tools.
|
|
# -clang-analyzer-core.NonNullParamChecker => Rationale: cannot be effective disabled, already checked by other checkers.

|

|
|
# -misc-include-cleaner => complains about no direct includes
|
|

|
|
# -cppcoreguidelines-non-private-member-variables-in-classes => Warning is too strict, manual review code review is preferred
|
|
# -cppcoreguidelines-pro-bounds-constant-array-index => gsl:at is not used by design
|
|
# -cppcoreguidelines-init-variables => reports false warnings for out parameters (other checkers are better to detect these problems)
|
|
# -cert-msc32-c => Rationale: predictable seed is by design (random used for testing, not crypto)
