Tcl provides a portable scripting environment for Unix, Windows, and Macintosh that supports string processing and pattern matching, native file system access, shell-like control over other programs, TCP/IP networking, timers, and event-driven I/O. Tcl has traditional programming constructs like variables, loops, procedures, namespaces, error handling, script packages, and dynamic loading of DLLs. Tk provides portable GUIs on UNIX, Windows, and Macintosh. A powerful widget set and the concise scripting interface to Tk make it a breeze to develop sophisticated user interfaces.
CMake is a cross-platform, open-source build system. It is used to control the software compilation process using simple platform and compiler independent configuration files. It generates native makefiles and workspaces that can be used in the compiler environment of your choice. CMake is quite sophisticated: it is possible to support complex environments requiring system configuration, pre-processor generation, and code generation.
Google C++ Mocking Framework (or Google Mock for short) is a library for writing and using C++ mock classes. It was inspired by jMock, EasyMock, and Hamcrest, and designed with C++'s specifics in mind. It lets you create mock classes trivially using simple macros, supports a rich set of matchers and actions, handles unordered, partially ordered, or completely ordered expectations, and is extensible by users.
xCover is a code coverage library for C and C++. It uses non-standard features available with GCC 4.3+ and Visual C++ 7.0+. Users place line-marks in each branch of each function or method in a component's source file, and the library is able to produce, upon request, a report of which of these has not been executed. Reporting can be done on a per-file, per-alias, or per-file-group basis.
Oink is a collaboration of backends for the Elsa C and C++ frontend. It aims to be industrial-strength for immediate utility in finding bugs, extensible for ease in adding backends, and composable for ease in combining existing ones. It computes expression-level and type-level data flow, and statement-level intra-procedural control flow (by delegating to Elsa). It's easy to get started by using the two demo backends that print graphs of these flows. It also comes with a client of the data flow analysis that does type qualifier inference: Cqual++, a C/C++ frontend for Cqual. Whole-program analyses may be attempted using the linker imitator.
