vimrc.vim

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

It consists of two, well documented parts:

Installation

Just include with some package manager, like:

Plug 'sheerun/vimrc'

I recommend to use:

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

      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.

    set complete-=i
  • 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.

    set nrformats-=octal
  • 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 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

    let &backupdir = expand(s:dir) . '/backup//'
    let &undodir = expand(s:dir) . '/undo//'

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

    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$'
