No preview window

[silentjay]

When I open the plugin no preview window is shown.

My config is as follows:

  {
    "nvim-telescope/telescope.nvim",
    dependencies = {
      { "nvim-lua/plenary.nvim" },
      {
        "debugloop/telescope-undo.nvim",
        config = function(plugin, opts)
          require "plugins.configs.telescope" (plugin, opts) -- include the default astronvim config that calls the setup call
          local telescope = require "telescope"
          telescope.setup {
            pickers = { oldfiles = { cwd_only = true } }, -- only show files in current directory
            extensions = {
              undo = {
                use_delta = true,
                side_by_side = true,
                layout_strategy = "vertical",
                layout_config = {
                  preview_height = 0.8,
                },
              },
            },
          }
          telescope.load_extension "undo"
        end,
      },
    },
    keys = {
      { "<leader>fu", "<cmd>Telescope undo<cr>", desc = "Open File Undo His. in Telescope" },
    },
  },

Not sure if this is how I've had to integrate the plugin with astronvim's telescope integration. However changing layout_strategy to horizontal works as expected and the preview window is shown.

If you want the preview result just like in README, use horizontal rather than vertical. Maybe it's the author's negligence in the configuratiojn part of README.

Thanks as I mentioned horizontal works as expected, but was trying to get vertical to work. I suspect it might have something to do with my astronvim config but exactly what I couldn't work out. In the end I switched to a different plugin so I'll close this.

Hi, pretty sure the issue was unrelated to the plugin. If your notification in the screen shot is any indication, you config tried to attach a LSP client to the preview buffer, failed, and closed the window? I can only guess if that is indeed the reason, but feel free to reopen with more info if you want to get to the bottom of this.
