Static Analysis

Static analysis tools usually needs a compile_commands.json file. If you use Meson to build JackTrip, it already created this file in your build directory.

Scan-Build

If you only want to run basic static analysis on JackTrip, you can install scan-build. Meson will automatically generate a scan-build target for you:

ninja -C builddir scan-build

This should never show any warnings or errors.

Clang-Tidy

If you installed clang-tidy and there's a .clang-tidy file in the project directory, Meson generates a clang-tidy target, too. The .clang-tidy file defines which checks should be run. Running clang-tidy on the entire code base:

ninja -C builddir clang-tidy

In most cases you want to run clang-tidy on single files.

cd src
run-clang-tidy.py -j 4 -p ../builddir singlefile.cpp

In -j #, # specifies the number of tidy instances that run in parallel.

Fixes

For some checks clang-tidy offers automatic fixes. Some of these are save to apply without worries. Others should be checked afterwards.

run-clang-tidy.py -fix -j 4 -p ../builddir singlefile.cpp
