Hello @leobip, We usually call those rules “naming conventions”, and you can find the for instance by searching for that term: [https://rules.sonarsource.com/cpp?search=naming](https://rules.sonarsource.com/cpp?search=naming). Hope this helps, ---

Thanks Loic… Those rules are what I am using but I cannot get the ones referring to the names of the variables, Structs, macros and enums. In C ++ Language I’ve found them in Java and Python … it´s must be in C ++
