How can I use #pragma message() so that the message points to the file(lineno)?

Question

In order to add \'todo\' items into my code, I want to put a message in the compiler output.
I would like it to look like this:

c:/temp/main.cpp(104): TODO -         


        

Answer 1

just whipped this up now, and it sure beats my old solution of using #error :D

#define _STR(x) #x
#define STR(x) _STR(x)
#define TODO(x) __pragma(message("TODO: "_STR(x) " :: " __FILE__ "@" STR(__LINE__)))

you can modify this how ever you like/to whatever suits your needs. An example of its usage:

//in code somewhere
TODO(Fix this);

output in the console pane:

1>TODO: Fix this :: c:\users\administrator\documents\visual studio 2008\projects\metatest\metatest\metatest.cpp@33

only downside is you can't jump to the line of this (by double clicking the message in the console pane) using __pragma (but testing with #pragma it doesn't seem to be the case anyways...)
