[DGD] (Newbie Question #2) [user->message]

[Jason Murray]

Hi,

I would leave message() alone and begin by allowing the user to toggle
whether he or she wants to (or can) see ansi colors, both as a command
and at logon. Then use a query on the user's preference to build the
string passed to message(). The implementation is up to you. The
simplest, perhaps, is something like this:

#include "ansi_defs.h"

if (user->use_ansi()) {
    str = ANSI_FG_RED + "hello, world" + ANSI_END;
} else {
    str = "hello, world";
}

user->message(str);
