Introduction

Some macros such as assertion with message.

Examples

test_msg.cpp

#include <limbo/preprocessor/Msg.h>
 
int main()
{
    int a = 1; 
    int b = 2; 
 
    limboPrint(limbo::kDEBUG, "a = %d, b = %d\n", a, b); 
    limboAssertMsg(a+b < 3, "a+b fails to be less than 3: a+b = %d", a+b); 
 
    return 0; 
}

Compiling and running commands (assuming LIMBO_DIR is exported as the environment variable to the path where limbo library is installed)

g++ -o test_msg test_msg.cpp -I $LIMBO_DIR/include
./test_msg

Output

(D) a = 1, b = 2
(A) test_msg.cpp:14: int main(): Assertion `a+b < 3' failed: a+b fails to be less than 3: a+b = 3
Aborted
