" Description: A minimal, but feature rich, example .vimrc. If you are a
"              newbie, basing your first .vimrc on this file is a good choice.
"              If you're a more advanced user, building your own .vimrc based
"              on this file is still a good idea.

"------------------------------------------------------------
" Features
"------------------------------------------------------------
"
" These options and commands enable some very useful features in Vim, that
" no user should have to live without.

" Set 'nocompatible' to ward off unexpected things that your distro might
" have made, as well as sanely reset options when re-sourcing .vimrc
set nocompatible

" Attempt to determine the type of a file based on its name and possibly its
" contents.  Use this to allow intelligent auto-indenting for each filetype,
" and for plugins that are filetype specific.
filetype indent plugin on

" Enable syntax highlighting
syntax enable

" this is mostly a matter of taste. but LaTeX looks good with just a bit
" of indentation.
set sw=2
" TIP: if you write your \label's as \label{fig:something}, then if you
" type in \ref{fig: and press <C-n> you will automatically cycle through
" all the figure labels. Very useful!
"set iskeyword+=:

set textwidth=80


"------------------------------------------------------------
" Colors
"------------------------------------------------------------

set t_Co=256
colorscheme one-light


"------------------------------------------------------------
" Must have options
"------------------------------------------------------------

" These are highly recommended options.

" One of the most important options to activate. Allows you to switch from an
" unsaved buffer without saving it first. Also allows you to keep an undo
" history for multiple files. Vim will complain if you try to quit without
" saving, and swap files will keep you safe if your computer crashes.
set hidden

" Better command-line completion
set wildmenu

" Show partial commands in the last line of the screen
set showcmd

" Highlight searches (use <C-L> to temporarily turn off highlighting; see the
" mapping of <C-L> below)
set hlsearch



"------------------------------------------------------------
" Usability options
"------------------------------------------------------------

" These are options that users frequently set in their .vimrc. Some of them
" change Vim's behaviour in ways which deviate from the true Vi way, but
" which are considered to add usability. Which, if any, of these options to
" use is very much a personal preference, but they are harmless.

" Use case insensitive search, except when using capital letters
set ignorecase
set smartcase

" Allow backspacing over autoindent, line breaks and start of insert action
set backspace=indent,eol,start

" When opening a new line and no filetype-specific indenting is enabled, keep
" the same indent as the line you're currently on. Useful for READMEs, etc.
set autoindent
" set smartindent

" /taStop certain movements from always going to the first character of a line.
" While this behaviour deviates from that of Vi, it does what most users
" coming from other editors would expect.
set nostartofline

" Display the cursor position on the last line of the screen or in the status
" line of a window
set ruler

" Always display the status line, even if only one window is displayed
set laststatus=2

" Instead of failing a command because of unsaved changes, instead raise a
" dialogue asking if you wish to save changed files.
set confirm

" Use visual bell instead of beeping when doing something wrong
set visualbell

" And reset the terminal code for the visual bell.  If visualbell is set, and
" this line is also included, vim will neither flash nor beep.  If visualbell
" is unset, this does nothing.
set t_vb=

" Enable use of the mouse for all modes
set mouse=a

" Set the command window height to 1 line, to avoid many cases of having to
" "press <Enter> to continue"
set cmdheight=1

" Display line numbers on the left
set number

" Quickly time out on keycodes, but never time out on mappings
set notimeout ttimeout ttimeoutlen=200

" Use <F7> to toggle between 'paste' and 'nopaste'

set pastetoggle=<F7>
set showmode



"------------------------------------------------------------
" Indentation options
"------------------------------------------------------------

" Indentation settings according to personal preference.

" Indentation settings for using 2 spaces instead of tabs.
" Do not change 'tabstop' from its default value of 8 with this setup.
set shiftwidth=2
set softtabstop=2
set expandtab

" Indentation settings for using hard tabs for indent. Display tabs as
" two characters wide.
"set shiftwidth=2
set tabstop=2



"------------------------------------------------------------
" Mappings
"------------------------------------------------------------

" Useful mappings

" Map Y to act like D and C, i.e. to yank until EOL, rather than act as yy,
" which is the default
map Y y$

" Map <C-L> (redraw screen) to also turn off search highlighting until the
" next search
nnoremap <C-L> :nohl<CR><C-L>

" Open all folds while set.
set foldenable
set foldmethod=syntax

" Tab Manupulation
map <C-Q> :q<CR>
set selectmode=mouse,key
" map <F11>  :tabp<CR>

" Find the word under cursor
