title: Get name of the current file in Vim
body: <p>I'm trying to find the name of the file I'm editing inside of Vim. So I can use it to map <kbd>F5</kbd> to compile this file. Would of course be great if I could recognize the file format, and choose compiler accordingly, but really not necessary. If I find the name of the file, I could do that myself. But I really can't find any way to get the name of the file I'm editing.</p>
  
  <p>I know of the <code>:make</code> command, and have already mapped that, but for small scripts/testing programs, I really don't want to first have to write a simple makefile.</p>
