Install

1. Introduction:

   Installation requires [Git] and triggers [git clone] for each configured repository to ~/.vim/bundle/ by default. Curl is required for search.

2. Set up [Vundle]:

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

3. Configure Plugins:

   Put this at the top of your .vimrc to use Vundle. Remove plugins you don't need, they are for illustration purposes.

   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()
   
   " let Vundle manage Vundle, required
   Plugin 'VundleVim/Vundle.vim'
   
   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 `!` to update or just :PluginUpdate
   " :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. Install Plugins:

   Launch vim and run :PluginInstall

   To install from command line: vim +PluginInstall +qall

5. Install Powerline Fonts Font are used as part of Airline plugin

sudo apt-get install fonts-powerline

Short-Cuts

Enter Insert mode

• i - insert at the current position
• I - insert at the beginning of line
• a - append just after the current cursor position
• A - append at the end of line
• o - Open a new line below the current line
• O - Open a new line above the current line

Copy/Paste

Insert mode

In normal mode, one can copy (yank) with y{motion}, where {motion} is a Vim motion. For example, yw copies to the beginning of the next word. Other helpful yanking commands include:

• yy - or Y – yank the current line, including the newline character at the end of the line
• y$ – yank to the end of the current line (but don't yank the newline character); note that many people like to remap Y to y$ in line with C and D
• yiw – yank the current word (excluding surrounding whitespace)
• yaw – yank the current word (including leading or trailing whitespace)
• ytx – yank from the current cursor position up to and before the character (til x)
• yfx – yank from the current cursor position up to and including the character (find x) Cutting can be done using d{motion}, including:

dd - cut the current line, including the newline character at the end of the line To copy into a register, one can use "{register} immediately before one of the above commands to copy into the register {register}.

Pasting in normal mode

In normal mode, one can use p to paste after the cursor, or P to paste before the cursor.

The variants gp and gP move the cursor after the pasted text, instead of leaving the cursor stationary.

Pasting in insert mode

The contents of a register can be pasted while in insert mode: type Ctrl-r then a character that identifies the register. For example, Ctrl-r then " pastes from the default register, and Ctrl-r then 0 pastes from register zero which holds the text that was most recently yanked (copied)

Vim Screen Navigation

• G – Go to the end of the file.

• g – Go to the beginning of the file.

• H – Go to the first line of current screen.

• M – Go to the middle line of current screen.

• L – Go to the last line of current screen.

• ctrl+f – Jump forward one full screen.

• ctrl+b – Jump backwards one full screen

• ctrl+d – Jump forward (down) a half screen

• ctrl+u – Jump back (up) one half screen

• N% – Go to the Nth percentage line of the file.

• NG – Go to the Nth line of the file.

NERD Tree

• o to open the file in a new buffer or open/close directory.
• t to open the file in a new tab.
• i to open the file in a new horizontal split.
• s to open the file in a new vertical split.
• p to go to parent directory.
• r to refresh the current directory.

Vim Windows movement

• Ctrl + w (hjkl)
• Ctrl + ww

Vim Buffers

So every file you open will be placed in a Buffer, that can be displayed or not. You can cycle through buffers with

• :bnext and :bprev commands and list them all with the
• :buffers command.
• :buffers, :ls list all buffers
• :buffer [N] show the buffer with the provided number
• :bnext/:bprev show next/previous buffer
• :edit [filename] put a new file into a buffer
• :bdelete [N] delete the current buffer or the buffer [N]
• [N] Ctrl-^ go to buffer [N] or the previously shown buffer

Note that :q doesn’t delete a buffer, keeping it in memory, thus not removing from the buffer list.

Vim-Windows

A Vim Window is what you see and interact with. A Window always shows a Buffer, being it from a file or just an empty one. Many windows can be opened at the same time by splitting the editor.

• Ctrl-w s, :split [filename] split the window, optionally opening a new file
• Ctrl-w v, :vsplit [filename] split the window vertically, optionally opening a new file
• :sbuffer [N] split the window and open the buffer [N]
• :sball open all buffers in windows
• Ctrl-w w/Ctrl-w W go to next/prev window
• Ctrl-w [direction] go to the window at [direction]
• :q close a window (if it is the last window it also exits the editor)
• :qa close all windows and exit the editor Many famous Vim plugins like NERDTree uses Windows to show lists or the filesystem.

Buffer mappings - no plug-ins

" Mappings to access buffers (don't use "\p" because a
" delay before pressing "p" would accidentally paste).
" \l       : list buffers
" \b \f \g : go back/forward/last-used
" \1 \2 \3 : go to buffer 1/2/3 etc
nnoremap <Leader>l :ls<CR>
nnoremap <Leader>b :bp<CR>
nnoremap <Leader>f :bn<CR>
nnoremap <Leader>g :e#<CR>
nnoremap <Leader>1 :1b<CR>
nnoremap <Leader>2 :2b<CR>
nnoremap <Leader>3 :3b<CR>
nnoremap <Leader>4 :4b<CR>
nnoremap <Leader>5 :5b<CR>
nnoremap <Leader>6 :6b<CR>
nnoremap <Leader>7 :7b<CR>
nnoremap <Leader>8 :8b<CR>
nnoremap <Leader>9 :9b<CR>
nnoremap <Leader>0 :10b<CR>
" It's useful to show the buffer number in the status line.
set laststatus=2 statusline=%02n:%<%f\ %h%m%r%=%-14.(%l,%c%V%)\ %P

Vim-Tabs

A tab can show one or more windows and if more than one tab exists a list of tabs is shown at the top of the editor, much like tabs in a browser.

• :tabnew [filename] create a new tab, optionally opening a file
• gt/gT , :tabnext/:tabprev show next/previous tab
• :tab sball open all buffers in tabs
