vimrc.vim

This plugin replaces lion's share of my .vimrc. A superset of vim-sensible.

It consists of two, well documented parts:

vim-sensible defaults
extra configuration

Installation

Just include with some package manager, like:

Plug 'sheerun/vimrc'

I recommend to use:

vim-plug as lightweight plugin manager
vim-polyglot for syntax highlighting

Example for simple .vimrc file:

" Select your Leader key
let mapleader = "\<Space>"

" vimrc includes this additional color scheme
colorscheme wombat256mod

call plug#begin()

Plug 'sheerun/vimrc'
Plug 'sheerun/vim-polyglot'
" Load other plugins

call plug#end()

" Define maps for your plugins
nnoremap <Leader>o :CtrlP<CR>

Features

Basics

Disable strange Vi defaults.
```
set nocompatible
```

Turn on filetype plugins (:help filetype-plugin).

if has('autocmd')
  filetype plugin indent on
endif

Enable syntax highlighting.
```
if has('syntax')
  syntax enable
endif
```
Autoindent when starting new line, or using o or O.
```
set autoindent
```
Allow backspace in insert mode.
```
set backspace=indent,eol,start
```
Don't scan included files. The .tags file is more performant.
```

```
Use 'shiftwidth' when using <Tab> in front of a line. By default it's used only for shift commands (<, >).
```
set smarttab
```
Disable octal format for number processing.
```

```
Allow for mappings including Esc, while preserving zero timeout after pressing it manually.
```
set ttimeout
set ttimeoutlen=100
```
Enable highlighted case-insensitive incremential search.
```
set incsearch
```

Indent using two spaces.

set tabstop=2
set shiftwidth=2
set expandtab

Use Ctrl-L to clear the highlighting of :set hlsearch.
```
nnoremap <silent> <C-L> :nohlsearch<CR><C-L>
```
Always show window statuses, even if there's only one.
```
set laststatus=2
```
Show the line and column number of the cursor position.
```
set ruler
```
Show the size of block one selected in visual mode.
```
set showcmd
```
Autocomplete commands using nice menu in place of window status. Enable Ctrl-N and Ctrl-P to scroll through matches.
```
set wildmenu
```
When 'wrap' is on, display last line even if it doesn't fit.
```
set display+=lastline
```
Force utf-8 encoding
```
set encoding=utf-8
```

Set default whitespace characters when using :set list

set listchars=tab:>\ ,trail:-,extends:>,precedes:<,nbsp:+

Delete comment character when joining commented lines

if v:version > 703 || v:version == 703 && has("patch541")
  set formatoptions+=j
endif

Search upwards for tags file instead only locally

if has('path_extra')
  setglobal tags-=./tags tags^=./tags;
endif

Reload unchanged files automatically.
```
set autoread
```
Support all kind of EOLs by default.
```
set fileformats+=mac

```
set history=1000
```

```
set tabpagemax=50

```
set viminfo^=!
```

Enable backup and undo files by default.

let s:dir = has('win32') ? '$APPDATA/Vim' : isdirectory($HOME.'/Library') ? '~/Library/Vim' : empty($XDG_DATA_HOME) ? '~/.local/share/vim' : '$XDG_DATA_HOME/vim'
let &backupdir = expand(s:dir) . '/backup//'
let &undodir = expand(s:dir) . '/undo//'
set undofile

Allow color schemes to do bright colors without forcing bold.

if &t_Co == 8 && $TERM !~# '^linux'
  set t_Co=16
endif

Load matchit.vim, but only if the user hasn't installed a newer version.

if !exists('g:loaded_matchit') && findfile('plugin/matchit.vim', &rtp) ==# ''
  runtime! macros/matchit.vim
endif

Ctrl-U in insert mode deletes a lot. Use Ctrl-G u to first break undo, so that you can undo Ctrl-U without undoing what you typed before it.
```
inoremap <C-U> <C-G>u<C-U>
```

Avoid problems with fish shell (issue).

if &shell =~# 'fish$'
  set shell=/bin/bash
endif

Extras

Set monako font if using macvim

if has("gui_macvim")
  set guifont=Monaco:h13
endif

Keep flags when repeating last substitute command.
```
nnoremap & :&&<CR>
xnoremap & :&&<CR>
```
Y yanks from the cursor to the end of line as expected. See :help Y.
```
nnoremap Y y$
```

Automatically create directories for backup and undo files.

if !isdirectory(expand(s:dir))
  call system("mkdir -p " . expand(s:dir) . "/{backup,undo}")
end

Use more readable color scheme by default. It works well with :set colorline option.
```
colorscheme wombat256mod

Enable saving by Ctrl-s

nnoremap <C-s> :w<CR>
inoremap <C-s> <ESC>:w<CR>

Use Q to intelligently close a window (if there are multiple windows into the same buffer) or kill the buffer entirely if it's the last window looking into that buffer.

function! CloseWindowOrKillBuffer()
  let number_of_windows_to_this_buffer = len(filter(range(1, winnr('$')), "winbufnr(v:val) == bufnr('%')"))
  if matchstr(expand("%"), 'NERD') == 'NERD'
    wincmd c
    return
  endif
  if number_of_windows_to_this_buffer > 1
    wincmd c
  else
    bdelete
  endif
endfunction
nnoremap <silent> Q :call CloseWindowOrKillBuffer()<CR>

Set window title by default.
```
set title

Always focus on splited window.

nnoremap <C-w>s <C-w>s<C-w>w
nnoremap <C-w>v <C-w>v<C-w>w

Don't display the intro message on starting Vim.
```
set shortmess+=I
```

Use Silver Searcher for CtrlP plugin (if available) Fallback to git ls-files for fast listing. Because we use fast strategies, disable caching.

let g:ctrlp_use_caching = 0
if executable('ag')
    set grepprg=ag\ --nogroup\ --nocolor
    let g:ctrlp_user_command = 'ag %s -l --nocolor -g ""'
else
  let g:ctrlp_user_command = ['.git',
    \ 'cd %s && git ls-files . -co --exclude-standard',
    \ 'find %s -type f' ]

Make sure pasting in visual mode doesn't replace paste buffer

function! RestoreRegister()
  let @" = s:restore_reg
  return ''
endfunction
function! s:Repl()
  let s:restore_reg = @"
  return "p@=RestoreRegister()\<cr>"
endfunction
vmap <silent> <expr> p <sid>Repl()

Prevent common mistake of pressing q: instead :q
```
map q: :q
```

Make a simple "search" text object. http://vim.wikia.com/wiki/Copy_or_change_search_hit It allows for replacing search matches with cs and then /././.

vnoremap <silent> s //e<C-r>=&selection=='exclusive'?'+1':''<CR><CR>
    \:<C-u>call histdel('search',-1)<Bar>let @/=histget('search',-1)<CR>gv
omap s :normal vs<CR>
