A game debug console - help
Author
I have this little game debug console thing. It all works nice and fins and everything, I just want to simplyfy the syntax for it. The way I have it now, you can just spit messages out to the console, like so
sConsole() << "here is some message";
sConsole().End();
The End() method adds the constructed string finally to the console, and prepares for another msg, etc. what I want to be able to do is
sConsole() << "here is some message" << End();
But I cannot figure out for the life of me the syntax to allow this to work. Any help?
btw - I dont just have an ''End'' function, I have other functions such as changing the current color of the text, etc...

Simple.
You need to overload the ''<<'' operator - check google for C++ operator overloading. A suggestion of mine would be the following:

// struct that is used to set the colorstruct SetColor{ int mColor; // actual color value // constructor that initializes member SetColor(const int nColor) : mColor(nColor) {} // convert to integer const operator int() const { return mColor; }};// just an empty typestruct End {};class Console{ // other stuff here void SetColor(cont int nColor) { // change our text color for output here } // text output Console& operator << (const string& strText) { // call your printing function here return *this; } // end output Console& operator << (const End& sEnd) { return (*this << "\n"; // or whatever you use to end } // change output color Console& operator << (const SetColor& sColor) { SetTextColor(sColor); return *this; }};// usage exampleConsole sColor;sColor << "This is a " << SetColor(GREEN) << "green" << SetColor(GREY) << " text" << End(); Just my 0.02€,

Ohhhhhhh I see now.... so the End() would not actually be a method but a struct/class called End but then overloaded by the Console so simply end the line?
thanks much for the help, i was thinking it would be more of a method than overloading for a constructed object
thx

Actually, I was gonna post my SDL based pluggable console here in a bit, but what I did for it was this:
That way, you can do things like:
I hope that makes sense.
class SDL_Console{public: // some stuff // Stream operators enum OpFlag { Flush = 0x01, Exec = 0x02, Term = Flush | Exec }; SDL_Console& operator<<(OpFlag op); // some other stuff};SDL_Console& SDL_Console::operator<<(SDL_Console::OpFlag of){ if(of & Exec) Execute(m_stringBuffer.str()); if(of & Flush) { Out(m_stringBuffer.str()); m_stringBuffer.str(""); } return *this;} That way, you can do things like:
con << "echo here" << SDL_Console::Term;// output: "here"con << "echo this" << SDL_Console::Exec << " is a test" << Flush;// output: this// output: echo this is a test I hope that makes sense.
