Hold on! It already exists:

std.file.readText
std.string.splitLines

GULP!  This language is so powerful!  Do I dare ask a followup question?
I will try the readText.splitLines().  Thanks to all!

Thanks Jesse.
I'm finding that I can't just substitute args[1] for a text string.  Is there a clever way to use args[] in place of your "file.in"?

Why not?

void main(string[] args) {
    if(args.length > 1) {
        foreach(line; readText(args[1]).splitLines()) ...
    }
}

This is my program:

import std.stdio,std.string,std.file;

// Main function
void main(string[] args){
    if (args.length > 1){
        foreach(line; readText(args[1]).splitLines()) {
            writefln("line : %s", line);
            //if (n > 10) break;
        }
    }
}

I get this:

std.utf.UTFException@std\utf.d(644): Invalid UTF-8 sequence (at index 1)

These are the first few lines of my text file:

  What are you reading? If it's regular text (0-127) then you
shouldn't have an issue. However 128-255 (or, -1 to -127) are
treated differently. D by default is UTF-8 or unicode encoded,
meaning it wants to see valid encodings that follow that
structure.

  Unfortunately I don't have good references of how to simply
convert old Ascii to a utf-8 (within Phobos). I have my own
workaround...

I am trying to write simple parser, that split text to
key value

name = david
lastname = wood

here is my code:

		foreach (line; readText(confname).splitLines())
		{
			writeln(line);
			foreach (str; split(line, "="))
			{
				writeln(str);	
			}
		}

now it's look like my code are put at str something wrong. I tried to do writeln(str[0]) but it's put there only first letters from first row.

Also could anybody help me to find example how create structure and than fill it's with value field.
