I'm using the following to read arrays from the command line (or redirected file) but am having some issues that I have not been able to solve on my own. Would appreciate if a little guidance. void f(T)(ref T a)if(isArray!T) { a.length = 100; int i; if(i == a.length) a.length *= 2; a.length[--i]; } how do it terminate the input (or clear the buffer) such that subsequent calls to readf are not ignored? int[] i; f(i); // no matter how many time I call readf() after this point it is all always ignored double d; readf(" %s", &d); // not called how do i read a string[] such that whitespace (all or one of my choosing) delineate the string boundary? readf(" %s ", &data) sort of does the trick for spaces but it leaves all newlines embedded in substrings. Assuming that input is provided one string per line, readf(" %s\n", &data) line separated by spaces an exception is immediately thrown from std.format. Thanks, Andrew

In case you're ever reading from a file you can do: string input = cast(string)std.file.read("filename"); string[] text = input.split();
