I'm afraid that any variation of
Code:
printf '%s' "string"

messes up all the 'display'.
And i dont want to use eval to get the colors prints properly, as i dont want to execute other possible variables placed as output. (See 5th post - 1st -enlared post to it)

Sorry I forgot to add solved.

Tk_GetDash(3TK) 					       Tk Library Procedures						   Tk_GetDash(3TK)

__________________________________________________________________________________________________________________________________________________

NAME

       Tk_GetDash - convert from string to valid dash structure.

SYNOPSIS

       #include <tk.h>

       int
       Tk_GetDash(interp, string, dashPtr)

ARGUMENTS

       Tcl_Interp	    *interp(in)
				      Interpreter to use for error reporting.

       CONST char *	    string(in)
				      Textual value to be converted.

       Tk_Dash	 *dashPtr   (out)     Points to place to store the dash pattern value converted from string.
_________________________________________________________________

DESCRIPTION

       These  procedure  parses  the  string and fills in the result in the Tk_Dash structure. The string can be a list of integers or a character
       string containing only [.,-_] or spaces. If all goes well, TCL_OK is returned. If string doesn't have the proper syntax then  TCL_ERROR	is
       returned, an error message is left in the interpreter's result, and nothing is stored at *dashPtr.

       The  first possible syntax is a list of integers. Each element represents the number of pixels of a line segment. Only the odd segments are
       drawn using the "outline" color. The other segments are drawn transparent.

       The second possible syntax is a character list containing only 5 possible characters [.,-_ ]. The space can be used to  enlarge	the  space
       between other line elements, and can not occur as the first posibion in the string. Some examples:
	   -dash .     = -dash {2 4}
	   -dash -     = -dash {6 4}
	   -dash -.    = -dash {6 4 2 4}
	   -dash -..   = -dash {6 4 2 4 2 4}
	   -dash {. }  = -dash {2 8}
	   -dash ,     = -dash {4 4}

       The  main  difference  of this syntax with the previous is that it it shape-conserving. This means that all values in the dash list will be
       multiplied by the line width before display. This assures that "." will always be displayed as a dot and "-" always as a dash regardless of
       the line width.

       On  systems where only a limited set of dash patterns, the dash pattern will be displayed as the most close dash pattern that is available.
       For example, on Windows only the first 4 of the above examples are available. The last 2 examples will  be  displayed  identically  as  the
       first one.

KEYWORDS

       dash, conversion
