如何在我的 .vimrc 文件中检测 OS X，因此某些配置仅适用于 OS X? [英] how do I detect OS X in my .vimrc file, so certain configurations will only apply to OS X?

问题描述

我在我的笔记本电脑 (OS X) 和几台服务器 (Solaris & Linux) 上使用我的 .vimrc 文件，并且假设有一天可以在 Windows 机器上使用它.我知道如何检测 unix 和 windows，但如何检测 OS X?(就此而言，有没有办法区分 Linux 和 Solaris 等.是否有一个包含has"可以接受的所有字符串的列表?我的 Google-fu 什么也没找到.)

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.)

例如，我会使用这样的东西:

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

但显然mac"不是正确的字符串，我尝试过的任何其他字符串也不是.

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

更新:下面的答案(macunix")似乎很明显应该工作，但由于某种原因它没有.(也许 Apple 没有正确编译 vim 来回应这个问题?似乎不太可能.)

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.)

无论如何，我想我需要转移问题的焦点:有没有人有可以达到相同目的的解决方案?(也就是说，成功检测到 .vimrc 文件正在 Mac OS X 上使用.)

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.)

推荐答案

我更新的 .vimrc 现在使用以下内容:

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

我的原答案如下

你可以试试我在我的 .vimrc 中所做的:

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

虽然，为了完全透明，我的实际 .vimrc 内容如下:

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

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

主要用于检测 Linux(相对于 OSX)

Mainly for detecting Linux (as opposed to OSX)

我不确定你是否绝对必须这样做 echo -n "$(uname)" 东西，但它与 uname 调用.您的里程可能会有所不同.

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.
