space-vim 的模块化设计取自于 spacemacs，其核心理念是 layer，可以点击这里查看 spacemacs 的 layer，点击这里查看 space-vim 的layer。其中，以 + 开头的目录我称之为 topic，其下层目录是该 topic 的一些 layer。LAYERS.md 是所有的 layer 清单。

.spacevim在 spacemacs 中，可以使用 .spacemacs 对 spacemacs 进行定制。与 spacemacs 相类似，space-vim 可以通过 .spacevim 来完成配置的个性化。.spacevim模板如下：
" Let Vim and NeoVim shares the same plugin directory.
" Comment it out if you don't like
let g:spacevim_plug_home = '~/.vim/plugged'
" Enable the existing layers in space-vim
function! Layers()
" Default layers
Layer 'fzf'
Layer 'unite'
Layer 'better-defaults'
endfunction
" Add your own plugins
function! UserInit()
" The default leader key is space key.
" Uncomment the line below and modify "<\Space>" if you prefer another
" let g:spacevim_leader = "<\Space>"
" The default local leader key is comma.
" Uncomment the line below and modify ',' if you prefer another
" let g:spacevim_localleader = ','
" Install personal plugins
" Plug 'hecal3/vim-leader-guide'
endfunction
" Override the default settings as well as adding extras
function! UserConfig()
" If you have installed the powerline fonts and want to enable airline layer
" let g:airline_powerline_fonts=1
" Use gui colors in terminal if available
if has('termguicolors')
set termguicolors
if g:spacevim_tmux
" If use vim inside tmux, see https://github.com/vim/vim/issues/993
" set Vim-specific sequences for RGB colors
let &t_8f = "\<Esc>[38;2;%lu;%lu;%lum"
let &t_8b = "\<Esc>[48;2;%lu;%lu;%lum"
endif
endif
endfunction
