Detailed introduction to Ubuntu vi configuration

Android source code development is almost inseparable from Linux. Of course, Ubuntu is the most recommended Linux system. The editing tool VI that comes with Linux, I believe everyone who has used it knows its power. However, the system comes with vi has limited functions and is certainly not very convenient to use, so we need to optimize and configure it.
1. Install the enhanced version of vi: sudo apt-get install vim
2. Make a soft link: sudo ln -sf /usr/bin/vim /usr/bin/vi This step can be omitted because it is just It's a matter of personal habits, but typing vi is probably faster than typing vim.
3. Create a new vi configuration file: sudo vi /etc/vim/vimrc.local. Add the following content in it and save it.
set nocompatible "Remove the annoying vim consistency mode and avoid some bugs and limitations of previous versions.
set number "Display the line number.
set ruler "Display the row and column information of the current cursor
syntax on "Syntax highlighting. (This is definitely required.)
set background=dark "The background color is dark. (I think it is good, protect your eyes.)

set hls "Find matches that are highlighted
set lbr "Do not break lines between words.
set fo+=mB "Turn on the line breaking module to support Asian languages ​​
set backspace=indent,eol,start

set vb t_vb= "When vim is editing, if the command is wrong, a beep will be emitted, this setting removes the beep
set incsearch "Start retrieval when the text to be retrieved has not been completely entered.
filetype plugin indent on "Enables Vim's three intelligences: automatic identification of file types,
autocmd FileType text setlocal textwidth =78
autocmd BufReadPost *
\if line("°\"")>0&&line("°\"") \ exe "normal g` \""|
\endif
highlight Search term=reverse ctermbg=4 ctermfg=7
highlight Normal ctermbg=black ctermfg=white

set completeopt=longest, menu

" Use the space bar to turn folding on and off
set foldenable
set foldmethod=manual

4. To add friendly support for Chinese, you need to modify a hidden file in the user directory
vi ~/.vimrc Add the following two lines:
let &termencoding=&encoding
set fileencodings=utf-8,gbk,ucs-bom,cp936

After completing the above steps, try using your vi to write a c code, it is very beautiful.
