Linux下 vim 的配置

为了能够复制粘贴到外面，需要下载gvim，可以自行下载。

我的插件管理是用vim-plug来管理的

下载命令

curl -fLo ~/.vim/autoload/plug.vim --create-dirs 
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

然后在vimrc中添加如下代码段

call plug#begin()
"""""中间放插件""""

call plug#end()

在中间放置需要的插件就可以了.

vim-plug管理插件时，只需要加入上面在代码段中加入需要的插件命(如下)，然后打开终端输入vim，在按：输入，PlugInstall，就可以完成插件安装。

我自己在使用的一些插件。

　neadtree　　管理目录用，我把快捷键设置成F3，可以让它开启或关闭

    Plug 'scrooloose/nerdtree'

　nerdcommenter　　代码多行注释用的，还是挺不错的，按住 +c+space 就可以注释与反注释了

    Plug 'ddollar/nerdcommenter'

　airline、airline themes　　美化 vim 底部状态栏

    Plug 'vim-airline/vim-airline'
    Plug 'vim-airline/vim-airline-themes'

　airline使用前需要安装powerline字体

安装方法如下

# clone
git clone https://github.com/powerline/fonts.git --depth=1
# install
cd fonts
./install.sh
# clean-up a bit
cd ..
rm -rf fonts

airline的主题目录如下，可以选择自己想要的主题

~/.vim/plugged/vim-airline-themes/autoload/airline/themes

以下是我的觉得比较好看的主题。

aurora.vim         base16_eighties.vim  dracula.vim     onedark.vim     silver.vim 
badcat.vim         base16_isotope.vim   hybridline.vim  papercolor.vim  term.vim
badwolf.vim        base16_pop.vim       minimalist.vim  peaksea.vim     understated.vim
base16_colors.vim  bubblegum.vim        molokai.vim     ravenpower.vim  vice.vim
base16color.vim    deus.vim             night_owl.vim   raven.vim       wombat.vim

其他的主题就被我删了。

现在我再用的vice和tomorrow主题，我认为还是蛮好看的。

只要在.vimrc中添加

let g:airline_theme="vice"

就可以了。

最后是完整的.vimrc
