3. Problem-solving ideas
Since before the development is basically on Linux, see the topic needs to exe, so he plans to complete the development of the basic functions on the Linux platform, then compatible with Windows platforms.
3.1 Cross-Platform
In consideration of the cross-platform (Linux + Windows), so I chose a combination of CMake + Qt; compiling with CMake to achieve cross-platform, Qt cross-platform GUI display.
In the source code, in addition to Gui is Qt implementation does not need to consider their own cross-platform, all other functions of the system needs its own judgment, and then operate the appropriate platform.
3.2 program basically
To improve the scalability of programs, commands, options parser, respectively statistics were processed loosely coupled; makes the option parser, statistics can be different needs for policy replacement; command through inheritance decorative way to enhance the command function. Then, build a single command registrar example, commands to manage (see here, you can probably guess the command registry so that the program can support multiple commands simultaneously, rather than just a wc), improves the scalability.
3.2 wildcard support
The idea is to achieve a wildcard wildcard expression into a regular expression, then realized poller directory, and then recursively traverse, in line with the wildcard file name as an argument callback. Note: Because Linux and Windows terminal CMD wildcard will be resolved, so the need to use double quotes (Windows is a single quotation marks) to the wildcard expression in quotes.
3.3 graphical interface
The graphical interface is implemented using Qt, Qt provides a more aesthetically pleasing user interface.
More than 3.4 language support (customized -L)
This function is regarded as a comment line to statistics, options lines of code (-a) expansion. When implementing functionality requirements of the subject, we recognize that different languages have different ways of annotation, allows users to select the language, and then comment syntax statistics according to a user-selected language.
By way of the configuration file, read different languages comment syntax to achieve extend the language without the need for recompilation.

VI project summary
The project selected C / C ++ as a development language, CMake + Qt as a development tool, GCov \ LCov do code coverage checking.
The development effort follows the use of object-oriented thinking to solve the problem, continue to consider the level of software modules to minimize coupling module. Spend more software modules in the design aspects of time. In addition, this development is compatible with Linux and Windows two systems, in part to write compatible code also spent a lot more time.
The development process using a relatively large number of callbacks to enhance code reuse rate, which is relatively satisfied with their own place; but there is still insufficient, the code redundancy is still relatively high.
