" Default Gentoo configuration file for neovim
" Based on the default vimrc shipped by Gentoo with app-editors/vim-core
" $Id$

" 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.

" Neovim comes with sensible defaults, see:
" https://github.com/neovim/neovim/issues/2676
" Most of the general settings from Gentoo's vimrc have been dropped here.
" We add only some necessary fixes and a few Gentoo specific settings.

" {{{ 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
endif
" }}}

" {{{ Fix &shell, see bug #101665.
if "" == &shell
  if executable("/bin/bash")
    set shell=/bin/bash
  elseif executable("/bin/sh")
    set shell=/bin/sh
  endif

" files should default to bash. See :help sh-syntax and bug #101819.
