xRecurseDiff is a small program that can rapidly traverse entire directory trees to show the differences between different copies of the same file. It can be useful for code analysis, expecially for collaborative development. For example, it can analyze differences before a CVS/SVN submission or to resolve a conflict in concurrent editing.
Squale (Software QUALity Enhancement) provides models and associated tools to assess software quality and help improve it over time. Its models and tools know how to aggregate raw quality information (such as metrics) given by third party technologies into high-level factors, offer dashboards which present those factors and allow digging deeply into the code quality, show the evolution of quality over time, and give economical indicators about the return on investment of quality efforts.
SCC is a cross-platform tool that counts the number of lines in source code files. It features a GUI that gives the user complete control over which files are processed. Blank lines are counted separately from lines containing source code statements. Configurable regular expressions can be applied to count parts of source code files separately. Regular expressions are applied according to a file type rather than to all files. It can process any textual source code file, includingJava, C/C++/C#, Perl, Python, PHP, Ruby, and TCL. The line count is split between blank, counted, and remaining lines. Results and summaries can be exported to a CSV file for further processing.
