一、 vimrc基本设置

.vimrc

" Sample .vimrc file by Martin Brochhaus
" Presented at PyCon APAC 2012

" ============================================
" Note to myself:
" DO NOT USE <C-z> FOR SAVING WHEN PRESENTING!
" ============================================


" Automatic reloading of .vimrc
"" autocmd! bufwritepost .vimrc source %


" Better copy & paste
" When you want to paste large blocks of code into vim, press F2 before you
" paste. At the bottom you should see ``-- INSERT (paste) --``.

 set pastetoggle=<F2>
 set clipboard=unnamed


" Mouse and backspace
 set mouse=a  " on OSX press ALT and click
 set bs=2     " make backspace behave like normal again


" Rebind <Leader> key
" I like to have it here becuase it is easier to reach than the default and
" it is next to ``m`` and ``n`` which I use for navigating between tabs.
 let mapleader = ","


" Bind nohl
" Removes highlight of your last search
" ``<C>`` stands for ``CTRL`` and therefore ``<C-n>`` stands for ``CTRL+n``
 noremap <C-n> :nohl<CR>
 vnoremap <C-n> :nohl<CR>
 inoremap <C-n> :nohl<CR>


" Quicksave command
" noremap <C-s> :update<CR>
" vnoremap <C-s> <C-C>:update<CR>
" inoremap <C-s> <C-O>:update<CR>



" Quick quit command
"" noremap <Leader>e :quit<CR>  " Quit current window
"" noremap <Leader>E :qa!<CR>   " Quit all windows


" bind Ctrl+<movement> keys to move around the windows, instead of using Ctrl+w + <movement>
" Every unnecessary keystroke that can be saved is good for your health :)
 map <c-j> <c-w>j
 map <c-k> <c-w>k
 map <c-l> <c-w>l
 map <c-h> <c-w>h


" easier moving between tabs
 map <Leader>n <esc>:tabprevious<CR>
 map <Leader>m <esc>:tabnext<CR>


" map sort function to a key
"" vnoremap <Leader>s :sort<CR>


" easier moving of code blocks
" Try to go into visual mode (v), thenselect several lines of code here and
" then press ``>`` several times.
 vnoremap < <gv  " better indentation
 vnoremap > >gv  " better indentation


" Show whitespace
" MUST be inserted BEFORE the colorscheme command
 autocmd ColorScheme * highlight ExtraWhitespace ctermbg=red guibg=red
 au InsertLeave * match ExtraWhitespace /\s\+$/


" Color scheme
" mkdir -p ~/.vim/colors && cd ~/.vim/colors
" wget -O wombat256mod.vim http://www.vim.org/scripts/download_script.php?src_id=13400
 set t_Co=256
" color wombat256mod


" Enable syntax highlighting
" You need to reload this file for the change to apply
 filetype off
 filetype plugin indent on
 syntax on


" Showing line numbers and length
 set number  " show line numbers
 set tw=79   " width of document (used by gd)
 set nowrap  " don't automatically wrap on load
 set fo-=t   " don't automatically wrap text when typing
 set colorcolumn=80
 highlight ColorColumn ctermbg=233


" easier formatting of paragraphs
"" vmap Q gq
"" nmap Q gqap


" Useful settings
"" set history=700
"" set undolevels=700


" Real programmers don't use TABs but spaces
 set tabstop=4
 set softtabstop=4
 set shiftwidth=4
 set shiftround
 set expandtab


" Make search case insensitive
 set hlsearch
 set incsearch
 set ignorecase
 set smartcase


" Disable stupid backup and swap files - they trigger too many events
" for file system watchers
 set nobackup
 set nowritebackup
 set noswapfile


" Setup Pathogen to manage your plugins
" mkdir -p ~/.vim/autoload ~/.vim/bundle
" curl -so ~/.vim/autoload/pathogen.vim https://raw.githubusercontent.com/tpope/vim-pathogen/master/autoload/pathogen.vim
" Now you can install any plugin into a .vim/bundle/plugin-name/ folder
" call pathogen#infect()
