Detailed Description

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:

   #include "sdh/dbg.h"
   d = cDBG( true );
   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";

Constructor & Destructor Documentation

cDBG::cDBG	(	bool	flag = false,
		char const *	color = "red",
		std::ostream *	fd = &std::cerr
	)		[inline]

constructor: construct a cDBG object

Parameters:

flag	- the initial state of the flag, if true then messages sent to the object are printed. Default is false. Can be changed with SetFlag()
color	- the name of the color to use, default is "red". Can be changed with SetColor()
fd	- the ostream to use for output, default is stderr. Can be changed with SetOutput()

Member Function Documentation

bool cDBG::GetFlag

(

void

)

const [inline]

Get debug_flag of this cDBG object.

Definition at line 158 of file dbg.h.

void cDBG::PDM	(	char const *	fmt,
			...
	)

Print debug messages of printf like fmt, ... in the color set with SetColor, but only if debug_flag is true.

void cDBG::SetColor

(

char const *

color

)

[inline]

Set debug_color of this cDBG object to color. color is a string like "red", see util.py for valid names.

Attention:

The string is NOT copied, just a pointer is stored

Definition at line 170 of file dbg.h.

void cDBG::SetFlag

(

bool

flag

)

[inline]

Set debug_flag of this cDBG object to flag. After setting the flag to true debug messages are printed, else not.

Definition at line 149 of file dbg.h.

void cDBG::SetOutput

(

std::ostream *

fd

)

[inline]

Set output of this cDBG object to fd, which must be a file like object like sys.stderr
