What tools do you use for static code analysis?
code-analysis
Solution
I have been setting up a Hudson continuous integration (CI) build system for my Objective-C iPhone projects (iOS apps), and have compiled a varied list of tools that can be used to analyze my projects during a build:
Clang static analyzer: free, up-to-date stand-alone tool that catches more issues than the version of Clang included with Xcode 4. Active project. -- visit http://clang-analyzer.llvm.org
Doxygen: free documentation generation tool that also generates class dependency diagrams. Active project -- visit http://www.doxygen.nl
HFCCA (header-free cyclomatic complexity analyzer): free Python script to calculate code complexity, but without header files and pre-processors. Supports output in XML format for Hudson/Jenkins builds. Active project. -- visit http://code.google.com/p/headerfile-free-cyclomatic-complexity-analyzer
CLOC (count lines of code): free tool to count files, lines of code, comments, and blank lines. Supports diffing, so you can see the differences between builds. Active project. -- visit http://cloc.sourceforge.net
SLOCcount (source lines of code count): a free tool to count lines of code and estimate the costs and time associated with a project. Does not appear to be active. -- visit http://sourceforge.net/projects/sloccount and http://www.dwheeler.com/sloccount
AnalysisTool: free code analysis tool that measures code complexity and also generates dependency diagrams. Not active. Does not seem to work with Xcode 4, but I would love to get it working. -- visit http://www.karppinen.fi/analysistool
Problem
This question on Cyclomatic Complexity made me think more about static code analysis. Analyzing code complexity and consistency is occasionally useful, and I'd like to start doing it more. What tools do you recommend (per language) for such analysis? Wikipedia has a large list of tools, but which ones have people tried before? Edit: As David points out, this is not a completely unasked question when it comes to C/UNIX based tools.
