How do you let the line of text end with something other than \n?

[lewdie]

I am trying to write a function for a console app which will allow the user to enter in text using carriage returns and end the line upon input of a period (.). I, for the life of me, cannot figure it out.


I would like to overload the following function for ease of use:

inline void get_line(string & s)
{
    cout.flush();
    if (cin.peek() == '\n')
    {
        cin.ignore(); 
    }
    getline(cin, s);
    return;
}

Anyone? =]

std::getline() can get an additional parameter, which is a delimiter char (default is '\n')

EDIT: @Romai:
I think he wants to read back from the buffered input upon pressing the period key.

Wait, this sounds suspicious.
What exactly are you trying to accomplish with this? Perhaps we can suggest a better way.

[chrisname]

Why is that suspicious? He wants to get the input buffer when '.' is pressed instead of '\n'. What's suspicious about that?

@OP,
That means you'll need to use raw mode. Use pdcurses or ncurses.

ncurses: http://www.gnu.org/software/ncurses/

It is suspicious because he is asking a question that might be better answered using a different mode of thought than what you assume he is trying to do.

[Albatross]

@Duoas: That's why we didn't give him the answer obtained by that mode of thought.

[Duthomhas]

Because I want to first know what he is thinking, rather than make wild stabs at random possibilities.

[Albatross]

I recognize your concerns Duoas, but I do believe that Ncurses couldn't be used to record keystrokes when the program using its library is not selected.

Well it could, in the same way system() could be used to delete system files. Just because it could be used for that, it doesn't mean it will.

Edit:

Or are we just going to operate under a "guilty until proven innocent" policy?
