A class to print colored debug messages.
- The printing can be switched on or off so the debug code can remain in the code. (default is off)
- The messages can be colorized (default is red).
- The output can be redirected. (default is sys.stderr)
- Debug messages can be printed in a functional way or in C++ stream like way
If the environment variable "SDH_NO_COLOR" is defined then the messages are printed without coloring (usefull for logging or if your terminal does not support colors.
Example:
g =
cDBG(
true,
"green" );
d.PDM( "This message is printed in default color red" );
g << "and this one in a nice green ";
g << "of course you can debug print any objects that have a string representation: " << 08 << 15 << true;
g << "Messages can be turned of and on, e.g. selected by command line options";
g.SetFlag(false);
g << "This messages is not printed";
