CPP directives like: 1) #if 2) #ifdef 3) #ifndef 4) #elif 5) #else 6) #endif
do form code blocks. Since, they don't make use of brackets, as a part of C language rule, their nested and repeated use can make the code very hard to read. Can even result it spaghetti code. This can be understood by this patch: https://lists.rtems.org/pipermail/devel/2020-April/058964.html The proposed idea is: 1) Nested CPP directives should follow same indentation rules as of nested conditional statements like 'if' and loops. 2) To mark which closing CPP directive (#endif) pairs with which opening CPP directive (#if or #ifdef or #ifndef), make use of comments. ex: #ifdef <some-macro> /* To test/verify/enable xyz */ ..... .... #endif /* To test/verify/enable xyz */ --Vaibhav Gupta _______________________________________________ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
