vim配置无插件

其实，vim插件会影响编辑器的启动速度，虽然有些插件影响不大，我依然觉得不够，其实通过简易的状态栏，可以显示必要的信息，能自定义颜色和背景甚至透明就足够了。

一、自定义状态栏
其实以下内容可以写在一行上，分开是为了方便添加内容和解释方便而已。
set statusline=%1*\%<%.50F\             "显示文件名和文件路径
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    "这一行和set statusline=%1是对应的，其他以此类推，实现了vim的背景透明
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

　　上边的内容：%number *\ ... \%*和hi User<number>对应，hi User<number>后面设置的颜色样式会应用到%number *\ ... \%*中的部分对应

二、创建新文件后自动加上文件头

在一些脚本文件中，往往通过头几行包含一些特殊信息，比如注释信息，作者信息，每次都手写非常麻烦。利用vim的自动添加功能，即可实现针对不同的文件，添加不同的信息，非常方便。通过自定义一个函数，根据时机调用函数即可：

"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

还有括号补全，引号补全，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。

全部的配置信息如下：

" All system-wide defaults are set in $VIMRUNTIME/debian.vim and sourced by
" the call to :runtime you can find below.  If you wish to change any of those
" settings, you should do it in this file (/etc/vim/vimrc), since debian.vim
" will be overwritten everytime an upgrade of the vim packages is performed.
" It is recommended to make changes after sourcing debian.vim since it alters
" the value of the 'compatible' option.

" This line should not be removed as it ensures that various options are
" properly set to work with the Vim-related packages available in Debian.
runtime! debian.vim

" Vim will load $VIMRUNTIME/defaults.vim if the user does not have a vimrc.
" This happens after /etc/vim/vimrc(.local) are loaded, so it will override
" any settings in these files.
" If you don't want that to happen, uncomment the below line to prevent
" defaults.vim from being loaded.
" let g:skip_defaults_vim = 1

" Uncomment the next line to make Vim more Vi-compatible
" NOTE: debian.vim sets 'nocompatible'.  Setting 'compatible' changes numerous
" options, so any other options should be set AFTER setting 'compatible'.
"set compatible

" Vim5 and later versions support syntax highlighting. Uncommenting the next
" line enables syntax highlighting by default.
if has("syntax")
  syntax on
endif

" If using a dark background within the editing area and syntax highlighting
" turn on this option as well
"set background=dark

" Uncomment the following to have Vim jump to the last position when
" reopening a file
"if has("autocmd")
"  au BufReadPost * if line("'\"") > 1 && line("'\"") <= line("$") | exe "normal! g'\"" | endif
"endif

" Uncomment the following to have Vim load indentation rules and plugins
" according to the detected filetype.
if has("autocmd")
  filetype plugin indent on
endif

" The following are commented out as they cause vim to behave a lot
" differently from regular Vi. They are highly recommended though.
"set showcmd        " Show (partial) command in status line.
"set showmatch      " Show matching brackets.
"set ignorecase     " Do case insensitive matching
"set smartcase      " Do smart case matching

 　每当进行编辑并运行自定义函数时让vim检查时间

function SetTimeOfDayColors()
    let currentHour = strftime("%H")
    echo "currentHour is " . currentHour
    if currentHour <  +
      let colorScheme = "darkblue"

set statusline +=\ %{SetTimeOfDayColors()}

1）vi -d file1 file2------文件比较功能，很方便
2）编辑一个文件的同时打开另一个文件  ：sp file 或者 ：vsp  file   横向和竖向比较，ctrl+w进行文件之间的切换，用于复制比较等还是不错
3）函数原型查找、数据结构原型查找，现在一般的vi安装后会自带ctags，用于简单的查找也很方便，在源代码的目录中执行 $ctags -R*,执行完以后会在代码的目录下创建一个tag文件，在阅读代码的时候如果想查找函数的原型、数据的定义直接用ctrl＋］跳转，返回用ctrl＋t。很简单、很方便。
补充俩，跟踪文件
：$         直接到达文件底部
：Num    直接到达Num行
：0         直接到达顶部

在有tag存在下，直接vi -t 函数名字，可以直达文件中的函数位置
