 - **Diagnostic cleanup**: When you close a file, its diagnostics are automatically cleared.
 - **Project file support**: You can feed your project file to cppcheck through the `--project` flag in the `cppcheck-official.arguments` field in the extension settings.
 - **Warning notes**: Display notes for warnings when those are available
-- **Dynamic config**: The extension supports running a script to generate arguments to pass to cppcheck. This can be done by including the command in the argument field wrapped with \@(), e.g. `--suppress=memleak:src/file1.cpp \@(bash path/to/script.sh)`. The script is expected to output the argument(s) wrapped with \@(). If the script e.g. creates a project file it should print out as `@(--project=path/to/projectfile.json)`. This output will be spliced into the argument string as such: `--suppress=memleak:src/file1.cpp --project=path/to/projectfile.json`.
