abaplint rules documentation
abaplint can be configured by placing a abaplint.json file in the root of the git repository. If no configuration file is found, the default configuration will be used, which contains have all rules enabled.Get default configuration by running abaplint -d > abaplint.json
abaplint-clean-code contains rule documentation as well as abaplint.json definitions which attempt to align abaplint with the official Clean ABAP styleguide.
