Alpha theme customization

[genebean]

I am working to port my neovim + lazy config to nixvim and can't quite figure out how I am supposed to translate this code:

return {
  "goolord/alpha-nvim",
  dependencies = {
    "nvim-tree/nvim-web-devicons",
  },

  config = function()
    local alpha = require("alpha")
    local dashboard = require("alpha.themes.startify")

    dashboard.section.header.val = {
      [[                                                                       ]],
      [[                                                                       ]],
      [[                                                                       ]],
      [[                                                                       ]],
      [[                                                                     ]],
      [[       ████ ██████           █████      ██                     ]],
      [[      ███████████             █████                             ]],
      [[      █████████ ███████████████████ ███   ███████████   ]],
      [[     █████████  ███    █████████████ █████ ██████████████   ]],
      [[    █████████ ██████████ █████████ █████ █████ ████ █████   ]],

      [[                                                                       ]],
      [[                                                                       ]],
      [[                                                                       ]],
    }

    alpha.setup(dashboard.opts)

    vim.cmd('autocmd User AlphaReady Neotree show')
  end,
}

I am hoping someone here can help me understand how this should be converted.

That config is basically loading a default theme, modifying it slightly and then passing it to alpha. It also triggers an autocmd.

Our config options aren't really optimized for this kinda imperative setup. Currently they can either assign a default theme with plugins.alpha.theme or define a custom theme using plugins.alpha.layout.

The situation might improve when we refactor the plugin to use a rfc42-style settings option, but for now I'd recommend avoiding the plugins.alpha options and instead manually adding your above config to extraConfigLua and adding pkgs.vimPlugins.alpha-nvim to extraPlugins.

Looks like @GaetanLepage was the last to refactor the plugin, so he might have a better suggestion as he'll be more familiar with it.

Thanks, that gets me unstuck. FWIW, this kind of setup is straight out of the docs for alpha at https://github.com/goolord/alpha-nvim/blob/main/doc/alpha.txt
