我怎么知道是否用文件名调用了vim？

Question

I'd like to add a switch in my .vimrc to do one thing if vim is being started up to edit an existing file or a new, empty buffer. In other words, I want to know if the command line call looked like this:

> vim

or this:

> vim myfile.txt

Is there a flag, argument, or file list I can examine to get this information?

You probably want to check ifeq (argc(),0) . http://vimhelp.appspot.com/eval.txt.html#argc%28%29
