Cppcheck Official

Cppcheck Official is a Visual Studio Code extension that runs cppcheck against C/C++ files upon save and reports any warnings or errors in the Problems panel.

Features

• On-save linting: When you save a c/cpp file, cppcheck is automatically run on that file.
• Per-file diagnostics: Only diagnostics relevant to the saved file are displayed.
• Configurable severity threshold: Filter out messages below a chosen severity level (info, warning, or error).
• Set C/C++ standard: Easily specify --std=<id> (e.g. c++17, c99, etc.).
• 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
