YAML

info

You can enable the extra with the :LazyExtras command. Plugins marked as optional will only be configured if they are installed.

Alternatively, you can add it to your lazy.nvim imports
lua/config/lazy.lua
require("lazy").setup({
  spec = {
    { "LazyVim/LazyVim", import = "lazyvim.plugins" },
    { import = "lazyvim.plugins.extras.lang.yaml" },
    { import = "plugins" },
  },
})

Below you can find a list of included plugins and their default settings.

caution

You don't need to copy the default settings to your config. They are only shown here for reference.
