CScout is a source code analyzer and refactoring browser for collections of C programs. It can process workspaces of multiple projects (a project is defined as a collection of C source files that are linked together) mapping the complexity introduced by the C preprocessor back into the original C source code files. CScout takes advantage of modern hardware (fast processors and large memory capacities) to analyze C source code beyond the level of detail and accuracy provided by current compilers and linkers. The analysis CScout performs takes into account the identifier scopes introduced by the C preprocessor and the C language proper scopes and namespaces. CScout has already been applied on projects of tens of thousands of lines to millions of lines, like the Linux, OpenSolaris, and FreeBSD kernels, and the Apache web server.

Building, Testing, Installing, Using

CScout has been compiled and tested on GNU/Linux (Debian jessie), Apple OS X (El Capitan), FreeBSD (11.0), and Cygwin. In order to build and use CScout you need a Unix (like) system with a modern C++ compiler, GNU make, and Perl. To test CScout you also need to be able to run Java from the command line, in order to use the HSQLDB database. To view CScout's diagrams you must have the GraphViz dot command in your executable file path.

  • To build run make. You can also use the -j make option to increase the build's speed.
  • To build and test, run make test.
  • To install (typically after building and testing), run sudo make install.
  • To see CScout in action run make example.

Under FreeBSD use gmake rather than make.

Testing requires an installed version of HSQLDB. If this is already installed in your system, specify to make the absolute path of the hsqldb directory, e.g. make HSQLDB_DIR=/usr/local/lib/hsqldb-2.3.3/hsqldb. Otherwise, make will automatically download and unpack a local copy of HSQLDB in the current directory.

Contributing

  • You can contribute to any of the open issues or you can open a new one describing what you want to do.
  • For small-scale improvements and fixes simply submit a GitHub pull request. Each pull request should cover only a single feature or bug fix. The changed code should follow the code style of the rest of the program. If you're contributing a feature don't forget to update the documentation. If you're submitting a bug fix, open a corresponding GitHub issue, and refer to the issue in your commit. Avoid gratuitous code changes. Ensure that the tests continue to pass after your change. If you're fixing a bug or adding a feature related to the language, add a corresponding test case.
  • Before embarking on a large-scale contribution, please open a GitHub issue.
