C Macros vs Rust Macros : r/rust - Reddit
2023年2月19日 · Declarative are simple, just allowing you to inject code like C ones do.

do {...} while (0) in macros : r/programming - Reddit
In modern C, macros are about as useful as they are in C++. Still the odd corner case where they're handy (e.g., X-macros ), but for everything else, just use inline functions, which are hygienic. (Caveat: embedded developers may be stuck using old old compilers using ancient standards that don't have inline functions)
Are C/C++ macros bad? : r/learnprogramming - Reddit
2022年9月13日 · In C/C++, macros are problematic because the compiler doesn't know it's happened. It's a preprocessing step which gets run before the compiler even processes the code.

Assembly but it's deeply cursed with macros : …
2021年5月3日 · Kind of hard to fit that into a reddit post.

List of Classic Warrior Macros : r/classicwow - Reddit
2020年11月23日 · 90% of these macros can be summarized with "add /startattack to each of your abilities" and "add an automatic stance change to stance-specific abilities".
