% Current as of latest clang-tidy-20 from Ubuntu 24.04 apt package
Requires cmake in "build" sub-directory with -DCMAKE_EXPORT_COMPILE_COMMANDS=ON (for "build/compile_commands.json")
and -DCMAKE_BUILD_TYPE=Debug (so `assert()`s defined), and then make (for Qt generated includes).
In project root directory (warning, slow):
clang-tidy-20 backend/*.c frontend/*.c backend_qt/*.cpp frontend_qt/*.cpp -p build/compile_commands.json
For "backend_tcl", which has no "compile_commands.json", specify the tcl include directory and package define, e.g.
clang-tidy-20 backend_tcl/*.c -- -I/usr/include/tcl8.6 -DPACKAGE_VERSION='"2.14.0"'
Options are in ".clang-tidy" (in the project root directory). The excluded check is
`clang-analyzer-security.insecureAPI.DeprecatedOrUnsafeBufferHandling` (for `sprintf()`).
The test suite (cmake given -DZINT_TEST=ON) can also be analysed with additional checks disabled:
clang-tidy-20 backend/tests/*.c frontend/tests/*.c backend_qt/tests/*.cpp \
-checks='-clang-analyzer-security.insecureAPI.strcpy,-clang-analyzer-optin.performance.Padding' \
-p build/compile_commands.json
