vim setup

1. Install vim and gvim

   • sudo apt-get install vim
   • sudo apt-get install vim-gnome

2. Install Vundle (Vim Plugin manager)

   • Clone Vundle repo: git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

3. create a new file in the .vim folder (touch vundle-vimrc.vim) and add the following lines to it:

    set nocompatible  " be iMproved, required
    filetype off  " required
   
    " set the runtime path to include Vundle and initialize
    set rtp+=~/.vim/bundle/Vundle.vim
    call vundle#begin()
    " alternatively, pass a path where Vundle should install plugins
    "call vundle#begin('~/some/path/here')
   
    " let Vundle manage Vundle, required
    Plugin 'VundleVim/Vundle.vim'
    " ADD PLUGINS AFTER THIS COMMENT. Use Plugin 'plugin_path'
   
    " All of your Plugins must be added before the following line
    call vundle#end()" required
    filetype plugin indent on" required
    " To ignore plugin indent changes, instead use:
    "filetype plugin on
    "
    " Brief help
    " :PluginList   - lists configured plugins
    " :PluginInstall- installs plugins; append `!`
    " :PluginUpdate - to update
    " :PluginSearch foo - searches for foo; append `!` to refresh local cache
    " :PluginClean  - confirms removal of unused plugins; append `!` to auto-approve removal
    "
    " see :h vundle for more details or wiki for FAQ
    " Put your non-Plugin stuff after this line
   

4. in the .vimrc add the following line:

   • source ~/.vim/vundle-vimrc.vim

       "Add Vundle config"
       source ~/.vim/vundle-vimrc.vim
     
       " Color-specific
       " examples 'bg=light'
       "colorscheme darkblue
       "set bg=dark
     
       " Turn on syntax coloring and line numbering.
       " Enable highlighting all search results.
       syn on
       set nu
       set hlsearch
     
       " Intentation settings.
       set tabstop=4
       set expandtab
       set shiftwidth=4
       set smartindent
     
       " Auto-wrap lines at X number of characters.
       set tw=100
     
       " Allow Vim to detect the filetype, useful for certain plugins.
       filetype plugin on
     
       " Tells Vim where to find cscope.
       set csprg=/usr/bin/cscope
     
       set number
     

if you don't have a .vimrc on your home(~/) directory create one (vim ~/.vimrc)
