How to integrate with alpha.nvim?

[fjchen7]

Follow the this guide in README.md I fail to integrate with alpha. I am trying to show all my saved sessions in alpha page. Is there an example? Very thanks!

Hi, I think alpha-nvim is more like a library for building startup screens, as it is actually quite challenging to build something with it (if not using one of the provided themes). That's why I didn't initially include a full example - it's quite user-specific.

But for a starting point you can try the following gist: https://gist.github.com/jedrzejboczar/618b531d1e0de6a956c66132287689aa. It uses some helpers copied from existing alpha-nvim themes and from my config. It creates a startup screen with your sessions, you can change the workspace definitions to suite your needs. You may also experiment with the layout, add some additional highlights in the create_button function, etc.

Thank you for response. I post my version here which may look more concise.

return {  -- lazy.nvim
  "goolord/alpha-nvim",
  event = "VimEnter",
  opts = function()
    local dashboard = require("alpha.themes.dashboard")
    dashboard.section.buttons.val = {
      dashboard.button("f", " " .. " Find Files", ":Telescope find_files<cr>"),
      dashboard.button("e", " " .. " New Files", ":ene <BAR> startinsert <CR>"),
      dashboard.button("o", " " .. " Recent Files", ":Telescope frecency <CR>"),
      dashboard.button("g", " " .. " Find Text", ":Telescope live_grep <CR>"),
      dashboard.button("c", " " .. " Nvim Config", [[<cmd>PossessionLoad config<CR>]]),
      dashboard.button("z", "鈴" .. " Lazy", ":Lazy<CR>"),
      dashboard.button("q", " " .. " Quit", ":qa<CR>"),
      (function()
        local group = { type = "group", opts = { spacing = 0 } }
        group.val = {
          {
            type = "text",
            val = "Sessions",
            opts = {
              position = "center"
            }
          }
        }
        local path = vim.fn.stdpath("data") .. "/possession"
        local files = vim.split(vim.fn.glob(path .. "/*.json"), "\n")
        for i, file in pairs(files) do
          local basename = vim.fs.basename(file):gsub("%.json", "")
          local button = dashboard.button(tostring(i), "勒 " .. basename, "<cmd>PossessionLoad " .. basename .. "<cr>")
          table.insert(group.val, button)
        end
        return group
      end)()
    }
    dashboard.opts.layout[1].val = 8
    return dashboard
  end,
  config = function(_, dashboard)
    require("alpha").setup(dashboard.opts)
  end,
}

Thanks, your example is definitely more concise. I added a link to your example in the README.

You could also try using require('possession.query').as_list() instead of manually globbing the JSON files - this will automatically respect your session_dir settings if you decide to change it in setup and will return a list with session objects so you can use e.g. the .name key. But of course your solution is ok and I don't plan any breaking changes regarding how/where the sessions are stored.
