I'm trying to make my gVim installation as portable as possible, and in doing so I want to put the _viminfo file in the $VIM directory rather than $HOME. I'm pretty new to hacking vimrc configurations, but here's what I've been trying:

let viminfopath=$VIM."\\_viminfo"
execute "set viminfo='1000,n".escape(viminfopath, ' ')

" Some other portability stuff.
set nobackup
set nowritebackup
if has("win32") || has("win64")
    set directory=$TMP
else
    set directory=~/tmp
end

This doesn't seem to be working, though; does anyone have any tips?

Thanks!

Edit: running :echo viminfopath gives the result F:\Programs\Vim\_viminfo, so the path itself is valid at least. It must be the execute operation that's not working.

You can use amix's suggestions: (I know the MySys approach can be done in different and better ways, but I think you can get the idea)

fun! MySys()
  return "windows"
endfun

set runtimepath=~/vim_local,$VIMRUNTIME
source ~/vim_local/vimrc

$VIMRUNTIME is the approach here, really interesting. Check amix's vimrc as well, there are some cross-plataform tips to get you started.

I'm thinking that if you use a backslash as your directory separator, you're going to break anything that isn't Windows.

let viminfopath=$VIM."\\_viminfo"

I would shoot for

let viminfopath=$VIM."/_viminfo"

instead. That should work in Windows as well as anything else.

Granted, that's a guess, but it's where I'd start.
