Modernize your C++ code
C++11 includes several additions to the core language and extends the C++ standard library. Some of these new features are very easy to use and bring a big added value to your C++ projects.
It's interesting to detect automatically places where we can use some C++11 new features. For such needs clang-modernize is a standalone tool used to automatically convert C++ code, written against old standards, to use features of the newest C++ standard where appropriate.
The CppDepend windows version integrates now the clang-modernize tool to detect the places where the following features could be used:
- Override: Detect places where you can add the override specifier to member functions that override a virtual function in a base class and that don’t already have the specifier
- Loop Convert: Detect loops like for(...; ...; ...) to replace them with the new range-based loops in C++11. And give you the new range loop expression to use.
- Pass-By-Value: Detect const-ref parameters that would benefit from using the pass-by-value idiom.
- auto_ptr: Detect the uses of the deprecated std::auto_ptr by std::unique_ptr.
- auto specifier: Detect places where to use of the auto type specifier in variable declarations.
- nullptr: Detect null literals to be replaced by nullptr where applicable.
How do I enable this feature?
This feature is not enabled by default, and you can enable it from "Project properties"=> Analysis=>Modernize C++ Code. However, it will take more time to analyse your code base and it's recommended to disable it as soon as you no longer need its results.
After the analysis you can find the CQLinq queries concerning the C++11 advices inside the "Modernize C++ Code" group:
And for each query, you can get the places where you can modernize your code. You can double click each result to go in your source code where the improvements could be applied.
