状态栏

我不是很喜欢用插件，因为我觉得插件会影响我编辑器的启动速度，虽然我知道有些插件影响得很小。比方说airline，它只会延迟100ms，但是我依然不想用，大概是有洁癖。所以我自己写了一个简易的状态栏，可以展示必要的信息，同时也可以自定义颜色。

set statusline=%1*\%<%.50F\             "显示文件名和文件路径 (%<应该可以去掉)
set statusline+=%=%2*\%y%m%r%h%w\ %*        "显示文件类型及文件状态
set statusline+=%3*\%{&ff}\[%{&fenc}]\ %*   "显示文件编码类型
set statusline+=%4*\ row:%l/%L,col:%c\ %*   "显示光标所在行和列
set statusline+=%5*\%3p%%\%*            "显示光标前文本所占总文本的比例
hi User1 cterm=none ctermfg=25 ctermbg=0 
hi User2 cterm=none ctermfg=208 ctermbg=0
hi User3 cterm=none ctermfg=169 ctermbg=0
hi User4 cterm=none ctermfg=100 ctermbg=0
hi User5 cterm=none ctermfg=green ctermbg=0

• %< 如果状态行过长，在何处换行
• %F 完整文件路径名
• %.50F 文件路径名长度不超过50，超过则进行缩写
• %= 在此之后的内容，显示在状态栏上时右对齐
• %y 文件类型
• %m 如果缓冲区已修改则表示为[+]
• %r 如果缓冲区为只读则表示为[RO]
• %h 如果为帮助缓冲区显示为[Help]
• %w 如果为预览窗口则显示为[Preview]
• %{&ff} 显示文件系统类型
• %{&fenc} 显示文件编码
• %l 光标所在行数
• %L 文件总行数
• %c 光标所在列数
• %p 当前行数占总行数的的百分比
• cterm:设置粗体，斜体，正体；ctermfg：前景色；ctermbg：背景色

%number *\ ... \%*和hi User<number>对应，hi User<number>后面设置的颜色样式会应用到%number *\ ... \%*中的...部分

vim效果图

背景透明

从上图我们不仅可以看到最下面的状态栏，还可以发现vim的背景是透明的。vim的背景透明是通过hi Normal ctermfg=252 ctermbg=none实现的，但是这条语句依赖于你的终端透明，它需要你的终端可以设置透明背景，我这里是ubuntu系统自带的终端。

创建新文件自动加上文件头

我喜欢在代码文件开头写一些注释，比如作者信息，因此我还希望我的vim可以根据我新创建的文件类型，自动选择相应的文件头。这个功能我觉得很棒。这个功能实现起来也非常简单，定义一个函数然后调用就可以了。

"创建文件头
autocmd BufNewFile *.py,*.tex exec ":call SetTitle()"
func! SetTitle() 
    if &filetype == 'python'
        call setline(1,"#!/usr/bin/env python3")
        call append(line("."),"# -*- coding:UTF-8 -*-")
        call append(line(".")+1,"##########################################################################")
        call append(line(".")+2, "# File Name: ".expand("%"))
        call append(line(".")+3, "# Author: stubborn vegeta")
        call append(line(".")+4, "# Created Time: ".strftime("%c"))
        call append(line(".")+5, "##########################################################################")
    endif
    if &filetype == 'plaintex'
        call setline(1,"% -*- coding:UTF-8 -*-")
        call append(line("."),"%#########################################################################")
        call append(line(".")+1, "% File Name: ".expand("%"))
        call append(line(".")+2, "% Author: stubborn vegeta")
        call append(line(".")+3, "% Created Time: ".strftime("%c"))
        call append(line(".")+4, "%#########################################################################")
    endif
    normal Go 
endfunc

下面分别是我新建一个python文件和新建一个LaTeX文件的效果图。

python

LaTeX

此外，还有括号补全，编译系统设置和一些快捷键设置，配置文件里都写的很清楚了。我没有设置引号补全，因为我写python时经常用三个引号，补全之后反而很麻烦。

" All system-wide defaults are set in $VIMRUNTIME/debian.vim and sourced by
