code_checker ~master

codechecker [](https://dev.azure.com/wikodes/wikodes/build/latest?definitionId=5&branchName=master)

code_checker is a tool that perform a quality check of C/C++ code. The intended use is as an automated sanity check of code before e.g. a pull request is accepted, a manual inspection by a human etc.

The feature that set it apart from other clang-tidy wrappers is its ability for re-analyze of failing or changed files. It keep track of passed files and their dependencies (header). If any dependency, or the file itselt, is changed it is re-analyzed. This significantly reduces the time it takes to run clang-tidy.

It also provides a convenient integration with iwyu.

Getting Started

code_checker depends on the following software packages:

• D compiler (dmd 2.079+, ldc 1.8.0+)
• clang-tidy (4.0+)

For users running Ubuntu one of the dependencies can be installed with apt.

sudo apt install clang-tidy

Download the D compiler of your choice, extract it and add to your PATH shell variable.

# example with an extracted DMD
export PATH=/path/to/dmd/linux/bin64/:$PATH

Once the dependencies are installed it is time to download the source code to install code_checker.

git clone https://github.com/joakim-brannstrom/code_checker.git
cd code_checker
dub build -b release

Done! The binary is place in build/. Have fun. Don't be shy to report any issue that you find.
