Is 'typedef super' a Useful Convention in C ?

Using "super" in C : An In-Depth Discussion

In C , the use of the "typedef super" convention has been employed by some developers to facilitate the access and manipulation of base classes within derived classes. While it offers certain advantages, its usage raises questions about its prevalence, practicality, and potential for standardization.

Prevalence and Acceptability

The practice of typedef'ing "super" is not particularly common in C codebases. However, it is not entirely uncommon either, especially among developers who prefer a concise and flexible coding style. The acceptability of this convention depends on the context and preferences of individual developers and teams.

Reasons for Consideration

There are several reasons why the use of "typedef super" might be considered:

• Convenience: It allows developers to use a convenient alias for the base class, streamlining constructor calls, method invocations, and other scenarios where the base class is referenced.
• Clarity: When dealing with complex or templated base classes, using "super" can improve code readability and prevent unnecessary repetition or clutter.
• Extensibility: The "super" convention enables chained inheritance, where methods from multiple levels of the inheritance hierarchy can be accessed using a consistent syntax.

Arguments Against Standardization

Despite its advantages, there are reasons why "super" has not been standardized as a keyword in C :

• Complexity: Implementing "super" as a keyword would introduce additional complexity to the C language syntax.
• Potential Ambiguity: In cases where multiple base classes are inherited, using a non-qualified "super" reference could lead to ambiguities.
• Availability of Workarounds: The use of typedefs provides a viable alternative to a dedicated "super" keyword, allowing developers to achieve similar functionality without modifying the language syntax.

Conclusion

While the typedef "super" convention offers certain benefits, its prevalence remains limited in C codebases. It is not a standardized practice and may not be suitable for all development scenarios. Nevertheless, for developers who value code readability, convenience, and extensibility, it can be a useful tool.
