Frama-C is a suite of tools dedicated to the analysis of the source code of software written in C. Frama-C gathers several static analysis techniques in a single collaborative framework. The collaborative approach allows static analyzers to build upon the results already computed by other analyzers in the framework. It provides sophisticated tools, such as a slicer and dependency analysis.
ShellCheck is a static analysis tool for shell scripts. Its goals are to point out and clarify typical beginner's syntax issues that causes a shell to give cryptic error messages, to point out and clarify typical intermediate level semantic problems that causes a shell to behave strangely and counter-intuitively, and to point out subtle caveats, corner cases, and pitfalls that may cause an advanced user's otherwise working script to fail under future circumstances.
