Is there a way to automatically generate getters and setters if they aren't present in C++?

The C++ Core Guidelines advise against using trivial getters and setters because they’re unnecessary and a symptom of bad object-oriented design. As such, C++ has no built-in functionality for auto-generating getters and setters (though metaclasses, if they ever get included in the language, would make this possible). This is related to the well-established software engineering principle tell, don’t ask.

In particular, mutating state via setters is usually a sign of code smell and a bad architectural design. There are exceptions from this rule, purely out of practicality. And this is fine, but the exceptions are few enough that they shouldn’t warrant tools to auto-generate getters and setters.

In fact, you may use this as a litmus test: whenever you find yourself wishing for a tool to autogenerate such boilerplate, take a step back and reconsider your code design.

That said, there exist a number of tools to provide the functionality and in purely practical terms they may prove useful, though I have not personally tested them:

• Visual Studio Code:
  • Getter and Setter Generator
  • Getter/Setter Generator
• Vim
  • vim-refactor
• Emacs
  • semantic-refactor
• Visual Studio
  • Resharper C++
  • Visual Assist
  • GS Assist
• CLion
  • built in
• Eclipse
  • built into Exclipse CDT (“Implement method”)

Not the compiler itself, but an IDE like eclipse CDT can actually perform this action automatcally (right click on class > Source > Generate Getters and Setters...).

You have to implement them yourself
