Simple Dired config for explorer

[donniebreve]

Hey all, I fell in love with the Dired experience in Emacs and never looked back. I am currently replicating that experience in NeoVim with Oil, but decided to try out @folke's Snacks.explorer plugin. Here's how you can replicate a single directory view, dired-jump, dired-up-directory and dired-find-file in Snacks.explorer:

return {
  "folke/snacks.nvim",
  priority = 1000,
  lazy = false,
  opts = {
    picker = {
      sources = {
        explorer = {
          layout = { preset = "ivy" },
          follow_file = true,
          auto_close = true,
          actions = {
            explorer_up_and_collapse = function(picker)
              picker:set_cwd(vim.fs.dirname(picker:cwd()))
              picker:find()
              require("snacks.explorer.tree"):close_all(picker:cwd())
            end,
            explorer_focus_or_confirm = function(picker, item, action)
              if item.dir then
                picker:set_cwd(item._path)
                picker:find()
              else
                require("snacks.explorer.actions").actions.confirm(picker, item, action)
              end
            end,
            explorer_collapse_and_close = function(picker)
              require("snacks.explorer.tree"):close_all(picker:cwd())
              picker:norm(function()
                picker:close()
              end)
            end
          },
          win = {
            list = {
              keys = {
                ["h"] = "explorer_up_and_collapse",
                ["l"] = "explorer_focus_or_confirm",
                ["q"] = "explorer_collapse_and_close"
              }
            }
          }
        }
      }
    },
    explorer = {
      enabled = true,
      replace_netrw = true,
    },
  },
  keys = {
    { "<leader>fd", "<cmd>lua require('snacks').explorer.open({ cwd = vim.fn.expand('%:p:h') })<cr>", desc = "Explorer" },
  }
}

explorer_collapse_and_close is required to ensure folders are collapsed if you exit the picker without selecting a file

I haven't used dired but this is cool.

I only changed in explorer_up_and_collapse the line picker:set_cwd(vim.fs.dirname(picker:cwd())) to picker:set_cwd(vim.fs.dirname(not item.dir and item.parent.file or item.file)), because Explorer follows the file that is currently open in a buffer and if that file is in a nested directory, then it will go up to the parent directory of the current working directory where Neovim is opened (e.g. current working directory is ~/.config/nvim/ and the explorer opens and follows the file in ~/.config/nvim/lua/plugins/snacks.lua and pressing h will go to ~/.config while I would expect it to go to ~/.config/nvim/lua/plugins/ directory).

But I guess that's just a personal preference after all. This probably happens because of the code here

snacks.nvim/lua/snacks/picker/core/filter.lua

Lines 40 to 41 in bc0630e

	local cwd = self.opts and self.opts.cwd
	self.cwd = type(cwd) == "string" and cwd or opts.cwd or uv.cwd() or "."

and cwd is nil and it resorts to uv.cwd().

Actually scratch that. It depends on the way you invoke the explorer. You use { "<leader>fd", "<cmd>lua require('snacks').explorer.open({ cwd = vim.fn.expand('%:p:h') })<cr>", desc = "Explorer" }, whereas I was using Snacks.explorer({ cwd = LazyVim.root() }) and that was resolving to the root of the current working directory. That was the difference.
