显示文件类型图标，美化spacevim

平台：arch linux

1. 安装nerd fonts字体
2. 设置配置文件
3. 添加插件"ryanoasis/vim-devicons"

首先要有nerd fonts字体

spacevim在安装时，会顺带下载nerd font字体

也可以自己安装，使用"yay nerd-fonts"就可以找到相关字体

然后设置一下spacevim的配置文件，美化一下:
(主要是将一些选项设置为true，并设置皮肤为onedark)

[options]
    # set spacevim theme. by default colorscheme layer is not loaded,
    # if you want to use more colorscheme, please load the colorscheme
    # layer
    colorscheme = "onedark"
    colorscheme_bg = "dark"

    # Disable guicolors in basic mode, many terminal do not support 24bit
    # true colors
    enable_guicolors = true
    # Disable statusline separator, if you want to use other value, please
    # install nerd fonts
    statusline_separator = "arrow"
    statusline_iseparator = "bar"
    buffer_index_type = 4
    windows_index_type = 3
    enable_tabline_filetype_icon = true
    enable_statusline_mode = true
    statusline_unicode = true
    # Enable vim compatible mode, avoid changing origin vim key bindings
    vimcompatible = true
    # filemanager = "defx"

[[layers]]
  name = 'colorscheme'

最后添加一个插件，用来显示文件类型图标。

在spacevim的配置文件中添加：

[[custom_plugins]]
  repo = "ryanoasis/vim-devicons"
  merged = false
