Hello,
I've got a pretty complicated macro inside my (unmanaged) C++ code. Is there any way to expand macros in VS debugger? Or maybe there is another way to debug macros there?
F.e. I'd like to place a breakpoint inside it.
(Yes, I know macros are bad...

Insert the expanded macro into your code.
Can read about with the macros expanded.
You can debug macros with VS macros IDE.
Macros are not that bad if used wisely.

In C, what is the proper way to define a printf like macro that will print only when DEBUG symbol is defined?
#ifdef DEBUG #define DEBUG_PRINT(???) ??? #else #define DEBUG_PRINT(???) ??? #endif
where ??? is where I am not sure what to fill in

Something like:

In general, I occasionally have a chain of nested macros with a few preprocessor conditional elements in their definitions. These can be painful to debug since it's hard to directly see the actual code being executed.
A while ago I vaguely remember finding...

This might not be applicable in your situation, but macros really do hamper debugging and often all together?
You should probably....
Debug the dissasembly with the symbols loaded.
Gcc -E will output the preprocessed source to stdout.

Hi,
I am using the following macro for printing debug information that I found on the web. It works great. However, I would like to turn-off debug printing for function A when debugging function B, which calls function A. I tried #define NDEBUG function...

#undef MY_DEBUG result = B(); #define MY_DEBUG....
You can do something like this though:
#if defined(NDEBUG) || !defined(MY_DEBUG(WHERESTR _fmt, WHEREARG, __VA_ARGS__) #endif /* NDEBUG */
Then, in function A():

Will not do anything.

There is a trace macro macros a try.
It'll send output to the debug channel.

I know that JavaScript doesn't support macros (Lisp-style ones) but I was wondering if anyone had a solution to maybe simulate macros? I Googled it, and one of the solutions suggested using eval(), but as he said, would be quite costly.
