" You can override any of these settings on a global basis via the
" "/etc/vim/nvimrc.local" file, and on a per-user basis via "~/.nvimrc".
" You may need to create these.

" {{{ General settings
" The following are some sensible defaults for Vim for most users.
set bs=2                " Allow backspacing over everything in insert mode
set ai                  " Always set auto-indenting on
set history=50          " keep 50 lines of command history
set ruler               " Show the cursor position all the time
set formatoptions+=j    " Delete comment character when joining commented lines

" Don't use Ex mode, use Q for formatting
map Q gq

" When doing tab completion, give the following files lower priority. You may
" wish to set 'wildignore' to completely ignore files, and 'wildmenu' to enable
" enhanced tab completion. These can be done in the user vimrc file.
set suffixes+=.info,.aux,.log,.dvi,.bbl,.out,.o,.lo

" When displaying line numbers, don't use an annoyingly wide number column. This
" doesn't enable line numbers -- :set number will do that. The value given is a
" minimum width to use for the number column, not a fixed size.
set numberwidth=3

" Use sensible whitespace indicators
set listchars=tab:>\ ,trail:-,extends:>,precedes:<,nbsp:+
" }}}

" {{{ Modeline settings
" We don't allow modelines by default. See bug #14088 and bug #73715.
" If you're not concerned about these, you can enable them on a per-user
" basis by adding "set modeline" to your ~/.vimrc file.
set nomodeline
" }}}

" {{{ Locale settings
" If we have a BOM, always honour that rather than trying to guess.
if &fileencodings !~? "ucs-bom"
  set fileencodings^=ucs-bom
endif

" Always check for UTF-8 when trying to determine encodings.
if &fileencodings !~? "utf-8"
  " If we have to add this, the default encoding is not Unicode.
  let g:added_fenc_utf8 = 1
  set fileencodings+=utf-8

" {{{ Syntax highlighting settings
" Switch syntax highlighting on, when the terminal has colors
" Also switch on highlighting the last used search pattern.
if &t_Co > 2 || has("gui_running")

  " include raw escapes in the file.

" Enable plugin-provided filetype settings, but only if the ftplugin
" directory exists (which it won't on livecds, for example).

  " indent settings. Some people don't like these, so we won't turn them on by
  " default.
