前些天升级了Archlinux，vi升级后的版本是vi-050325-1，结果之前设定好的高亮等配置都无效了。

vi,vim, gvim move to core and extra
I repost that, because now it will affect all users. In order to get the new vim layout installed you will have to remove some symlinks from the system:

Finally, the new vi* packages are up. There will be a little migration pain. For optimal results, I recommend to “sudo rm /usr/bin/{view,rview}” before you run “sudo pacman -Syu”

这是在Archlinux官方找到的信息！其实这里压根看不出比较有用的信息！顶多就是说最新的vi,vim, gvim如今已经被编制为正规军了，在更新vi之前要移除/usr/bin/{view,rview}，但是又不知道具体什么原因，说了等于没说…

看了一些帖子才知道，原来是vi现在搞独立了，不再和vim牵扯了！既然如此，还不如卸载了vi，完完全全用vim。

# 安装 vim
sudo pacman -S vim –noconfirm
# 卸载 vi
sudo pacman -R vi
# 做个软链接，执行 visudo 的时候需要调用vi
ln -s /usr/bin/vim /usr/bin/vi
# 复制 vimrc 样板文件到 /etc 目录下
cp /usr/share/vim/vim72/vimrc_example.vim /etc/vimrc

再编辑vimrc文件，适当修改来达到符合自己的爱好为止。

” for OpenVMS: sys$login:.vimrc

” When started as “evim”, evim.vim will already have done these settings.
if v:progname =~? “evim”

” Use Vim settings, rather then Vi settings (much better!).
” This must be first, because it changes other options as a side effect.

set incsearch ” do incremental searching
set nu “显示行号

” For Win32 GUI: remove ‘t’ flag from ‘guioptions’: no tearoff menu entries
” let &guioptions = substitute(&guioptions, “t”, “”, “g”)

” Don’t use Ex mode, use Q for formatting
map Q gq

” CTRL-U in insert mode deletes a lot. Use CTRL-G u to first break undo,
” so that you can undo CTRL-U after inserting a line break.

” In many terminal emulators the mouse works just fine, thus enable it.
