About

I wanted reports from CppCheck to appear in GitLab Merge Requests as Code Quality reports, which is a JSON file defined by the Code Climate team/service.

That's all this does: convert CppCheck XML to Code Climate JSON.

Usage

It is primarily used as a console script. As such, ensure you have Python 3's "scripts" directory in your PATH variable. For example, on Linux, that might be $HOME/.local/bin.

To test, try the --help or --version flags:

cppcheck-codequality --help

CppCheck already has a script to convert its XML report to HTML for easy human reading. See "Chapter 11 HTML Report" in the CppCheck Manual

This script follows that example and provides similar command-line options. A typical workflow might look like this:

# Generate CppCheck report as XML
cppcheck --xml --enable=warning,style,performance ./my_src_dir/ 2> cppcheck_out.xml
# Convert to a Code Climate JSON report
cppcheck-codequality --input-file cppcheck_out.xml --output-file cppcheck.json

If you wanted, you could invoke the script directly as a module, like this:

# Run as a module instead (note the underscore in the module name here)
python -m cppcheck_codequality --input-file=cppcheck_out.xml --output-file=cppcheck.json

Now, in your GitLab CI script, upload this file as a Code Quality report.

  artifacts:
    reports:
      codequality: cppcheck.json
