I found the answer to this question while writing it, so I’ve broadened it a little. I wanted to access the --servername argument, in order to create dynamic settings in my .vimrc file.

Through vim’s help, I found the v:servername variable, and my script is working. However, now I’m curious if it’s possible to access any arbitrary command-line argument. For example, if I wanted to know if vim was in Lisp mode (-l) or Debugging mode (-D), how would I do it? There seems to be no corresponding v: variable for them.

Here are the variables I found by autocompleting :help v:<Tab>

Is there a general way to access command-line arguments from vimscript?

    Strangely, I think the answer may be “No, there is no direct way to access startup options specified on the command line”.

    The :args command and argv() can be used to access the filename(s) specified on startup, but that’s not what you want.

    I see on Vim’s forums that someone offered this solution to get the startup command line on Linux:

    :exe '!tr "\0" " " </proc/' . getpid() . '/cmdline'

    I assume there’s analogous command on Windows. . . .

    You can look over that forum thread here:
