I’m working on a project and have a problem that I believe can be solved with macros, but given the nature of the issue I don’t have the experience to write one myself.
Here’s what I would expect as input and output of the #define macro:
Inputting code such as this
printf(foobar(Hello World.));
Should result in the preprocessor producing code that reads:
printf((char *)(std::string("")+'H'+'e'+'l'+'l'+'o'+' '+'W'+'o'+'r'+'l'+'d'+'.').c_str());
I’m assuming something this complicated is possible, and I hope one of you guys can help me out.
I NEED IT TO BE A MACRO, I DO NOT want a string constant anywhere.
The only solution I can think of is to run your code through a suitable script (probably just some light awk), that does the substitution before your code reaches the pre-compiler.
Depending on your environment you could do this as a “Pre-Build Event” in Visual Studio, or just add a step directly into your makefile.
