how do I detect OS X in my .vimrc file, so certain configurations will only apply to OS X?

I use my .vimrc file on my laptop (OS X) and several servers (Solaris & Linux), and could hypothetically someday use it on a Windows box. I know how to detect unix generally, and windows, but how do I detect OS X? (And for that matter, is there a way to distinguish between Linux and Solaris, etc. And is there a list somewhere of all the strings that 'has' can take? My Google-fu turned up nothing.)

For instance, I'd use something like this:

if has("mac")   " open a file in TextMate from vi: "   nmap mate :w<CR>:!mate %<CR> elseif has("unix")   " do stuff under linux and " elseif has("win32")   " do stuff under windows " endif 

But clearly "mac" is not the right string, nor are any of the others I tried.


UPDATE: The answer below ("macunix") seems fairly clearly like it should work, but for some reason it doesn't. (Perhaps Apple didn't compile vim properly to respond to this? Seems unlikely.)

At any rate I guess I need to shift the focus of the question: does anyone have a solution that will achieve the same ends? (That is, successfully detecting that the .vimrc file is being used on Mac OS X.)

My updated .vimrc now uses the following:

if has("gui_running")   " Gvim   if has("gui_gtk2") || has("gui_gtk3")     " Linux GUI   elseif has("gui_win32")     " Win32/64 GVim   elseif has("gui_macvim")     " MacVim   else     echo "Unknown GUI system!!!!"   endif else   " Terminal vim endif 

My original answer is below


You could try what I do in my .vimrc:

if has("unix")   let s:uname = system("uname -s")   if s:uname == "Darwin"     " Do Mac stuff here   endif endif 

Although, to be completely transparent, my actual .vimrc reads:

let s:uname = system("echo -n \"$(uname)\"") if !v:shell_error && s:uname == "Linux" 

Mainly for detecting Linux (as opposed to OSX)

I'm not sure if you absolutely have to do that echo -n \"$(uname)\" stuff, but it had to do with the newline at the end of the uname call. Your mileage may vary.
