how to setup the trouble with snack.

[eahangari-8x8]

Hello everyone, Im new to nvim and lua but this is my snack config, can you please help me to setup the trouble.nvim with my snack. I love folke plugins 😍

return {
	"folke/snacks.nvim",
	dependencies = {

				opts = function(_, opts)
					return vim.tbl_deep_extend("force", opts or {}, {
						picker = {
							actions = require("trouble.sources.snacks").actions,
							win = {
								input = {
									keys = {
										["<c-t>"] = {
											"trouble_open",
											mode = { "n", "i" },

}

but I don't know how to setup the trouble, and the documentation for the pickers is difficult to follow for me because I know nothing on lua lang.

when I try to press CTRL-t on the lsp errors it shows me this error

E73: Tag stack empty

instead of showing the lsp error with trouble
thanks for your help

Try a minimal reproducible example of the configuration:

Code

-- Run with `nvim -u repro.lua repro.lua`

-- Reproduce:
--  :lua Snacks.picker.diagnostics()
--  <C-t>

vim.env.LAZY_STDPATH = '.repro'
load(vim.fn.system 'curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua')()

---@module 'snacks'

---@diagnostic disable-next-line: missing-fields
require('lazy.minit').repro {
  spec = {
    {
      'folke/trouble.nvim',
    },
    {
      'folke/snacks.nvim',
      dependencies = {
        { -- https://github.com/folke/snacks.nvim/blob/main/docs/picker.md?plain=1#L569-L596
          'folke/trouble.nvim',
          optional = true, -- Merge specs only if 'folke/trouble.nvim' is already imported
          specs = {
            'folke/snacks.nvim',
            opts = function(_, opts)
              return vim.tbl_deep_extend('force', opts or {}, {
                picker = {
                  actions = require('trouble.sources.snacks').actions,
                  win = {
		    -- When the cursor is within `input`
                    input = { keys = { ['<c-t>'] = { 'trouble_open', mode = { 'n', 'i' } } } },
                  },
                },
              })
            end,
          },
        },
      },
    },
    {
      'neovim/nvim-lspconfig',
      opts = {
        servers = {
          lua_ls = {},
        },
      },
      config = function(_, opts)
        for server, config in pairs(opts.servers) do
          require('lspconfig')[server].setup(config)
        end
      end,
    },
  },
}

But for me, it feels kind of odd. Here is a better approach:

-- Run with `nvim -u repro.lua repro.lua`

-- Reproduce:
--  :lua Snacks.picker.diagnostics()
--  <C-t>

vim.env.LAZY_STDPATH = '.repro'
load(vim.fn.system 'curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua')()

---@module 'snacks'

---@diagnostic disable-next-line: missing-fields
require('lazy.minit').repro {
  spec = {
    {
      'folke/trouble.nvim',
      specs = {
        { -- https://github.com/folke/snacks.nvim/blob/main/docs/picker.md?plain=1#L569-L596
          'folke/snacks.nvim',
          opts = function(_, opts)
            return vim.tbl_deep_extend('force', opts or {}, {
              picker = {
                actions = require('trouble.sources.snacks').actions,
                win = {
                  input = { keys = { ['<c-t>'] = { 'trouble_open', mode = { 'n', 'i' } } } },
                },
              },
            })
          end,
        },
      },
    },
    {
      'folke/snacks.nvim',
    },
    {
      'neovim/nvim-lspconfig',
      opts = {
        servers = {
          lua_ls = {},
        },
      },
      config = function(_, opts)
        for server, config in pairs(opts.servers) do
          require('lspconfig')[server].setup(config)
        end
      end,
    },
  },
}

@eahangari-8x8 I was confused and getting the same error because I was trying to use <c-t> thinking I could use it in the buffer view to open trouble. But the <c-t> keymap only applies when the picker is open. It takes the picker results them opens them up in trouble.
