| <h1>Running the analyzer from the command line</h1> |
| |
| <p> Static Analyzer is by design a GUI tool. Its purpose is to find buggy execution |
| paths in the program, and such paths are very hard to comprehend by looking at |
| a non-interactive standard output. It is possible, however, to invoke the |
| Static Analyzer from the command line in order to obtain analysis results, and |
| then later view them interactively in a graphical interface. The following |
| tools are used commonly to run the analyzer from the command line. Both tools |
| are wrapper scripts to drive the analysis and the underlying invocations of the |
| Clang compiler: |
| <ol> |
| <li><a href="scan-build.html">Scan-Build</a> |
| is an old and simple command-line tool that emits static analyzer warnings as HTML files while compiling your project. You can view the analysis results in your web browser. |
| </li> |
| <ul> |
| <li> |
| Useful for individual developers who simply want to view static analysis results at their desk, or in a very simple collaborative environment. |
| </li> |
| <li> |
| Works on all major platforms (Windows, Linux, macOS) and is available as a package in many Linux distributions. |
| </li> |
| <li> |
| Does not include support for cross-translation-unit analysis. |
| </li> |
| </ul> |
| <li><a href="codechecker.html">CodeChecker</a> |
| is a web server that runs the Static Analyzer on your projects on demand and maintains a database of issues. |
| </li> |
| <ul> |
| <li> |
| Perfect for managing large amounts of Static Analyzer warnings in a collaborative environment. |
| </li> |
| <li> |
| Generally much more feature-rich than scan-build. |
| </li> |
| <li>Supports incremental analysis: Results can be stored in a database, subsequent analysis runs can be compared to list the newly added defects.</li> |
| <li><a href="https://clang.llvm.org/docs/analyzer/user-docs/CrossTranslationUnit.html">Cross Translation Unit (CTU) analysis</a> is supported fully on Linux via CodeChecker.</li> |
| <li>Can run clang-tidy checkers too.</li> |
| <li>Open source, but out-of-tree, i.e. not part of the LLVM project.</li> |
| </ul> |
| </ol> |
