### Improvements in Maintainability:
|
||||||
|
|
||||||
- C-style casts have been replaced by C++ casts. C-style casts are difficult to search for. C++ casts provide compile time checking ability and express programmers' intent better, so they are safer and clearer.
|
- Setup of a Continuous Integration system that checks building and runs QA code in a wide range of GNU/Linux distributions (ArchLinux, CentOS, Debian, Fedora, OpenSUSE, Ubuntu) and releases. See https://gitlab.com/gnss-sdr/gnss-sdr
|
||||||
- The override special identifier is now used when overriding a virtual function. This helps the compiler to check for type changes in the base class.
|
- Creation of multi-system processing blocks, drastically reducing code duplication and maintainability time.
|
||||||
- Use of const container calls when result is immediately converted to a const iterator. Using these members removes an implicit conversion from iterator to const_iterator.
|
- Automated code formatting with clang-format. This tool is widely available and easy to integrate into many code editors, and it also can be used from the command line. It cuts time spent on adhering to the project's code formatting style.
|
||||||
- Improved control over minimum required versions for core dependencies.

|
||||||
- Application of the coding style guide in several source files, improving readability.
|
- Improvement in C++ usage: A number of unused includes have been removed. Order of includes set to: local (in-source) headers, then library headers, then system headers. This helps to detect missing includes.
|
||||||
- The software builds with C++11, C++14 and C++17 standards.

|
||||||
|
- A downside in portability: BLAS and LAPACK libraries are now required even in ARM devices.
|
||||||
|
- A downside in portability: the matio library >= 1.5.3 is a new required dependency. If not found, it is downloaded and built automatically at building time, but this requires libtool, automake and hdf5 already installed in the system.
