Explorer auto close when open files

[mau-mauricelim]

Is there any way to auto close the explorer when a new file is opened?

[drowning-cat]

opts = {
  picker = {
    sources = {
      explorer = {
        win = {
          list = {
            keys = {
              ['L'] = { 'L', { 'confirm', 'close' } },
              -- OR
              -- ['L'] = { { 'confirm', 'close' } },

[mau-mauricelim]

What is the difference between the first and second?

Also a follow up question. How can i set up a key as "confirm" BUT does not open the file. I.e. I still want the navigation but if its a file, dont open it in the buffer.

I want to be able to navigate quickly with hjkl but I dont want accidental opening of files.

1. They are the same, but the first one does not show a diagnostic error.
2. Basically, you want an action that only toggles a directory:

opts = {
  picker = {
    sources = {
      explorer = {
        actions = {
          toggle_dir = function(picker, item)
            if item.dir then
              picker:action 'confirm'
            end
          end,
        },
        win = {
          list = {
            keys = {
              ['l'] = 'toggle_dir',
              ['L'] = { { 'confirm', 'close' } }, ---@diagnostic disable-line: assign-type-mismatch

Magic! Thanks!

[mau-mauricelim]

I went back to check what I had changed since this solution was to add
focus = 'input'
and the above solution is no longer working. Version still remains the same.

[mau-mauricelim]

@drowning-cat was there a breaking since Apr 24? My following config does not seem to be working anymore.

        explorer = {
          actions = {
            go_in_if_dir = function(picker, item)
              if item.dir then
                picker:action 'confirm'
              end
            end,
          },
          win = {
          list = {
            keys = {
                ['l'] = 'go_in_if_dir', -- Same as ./custom/MiniFiles.lua
                ['L'] = { { 'confirm', 'close' } }, ---@diagnostic disable-line: assign-type-mismatch
                ['<CR>'] = { { 'confirm', 'close' } }, ---@diagnostic disable-line: assign-type-mismatch
              },
            },
          },
          focus = 'input',
        },

[drowning-cat]

win = {
  input = {
    keys = {
      ['l'] = 'go_in_if_dir', -- Same as { 'go_in_if_dir', mode = 'n' },

[mau-mauricelim]

Yes normal mode keys is what I want, but it seems to not be working. Even keys like the default h.

[mau-mauricelim]

keymaps if focus = 'input' is commented out:

The mapping above seems to be correct.

keymaps if focus = 'input' is enabled:

This mappings seems to be wrong, not the same as https://github.com/folke/snacks.nvim/blob/main/docs/picker.md#explorer
And my normal mode keymaps are not here.

Ah thanks, managed to figure it out.

So it seems focus = 'input' uses win.input.keys EVEN when in LIST mode (after escaping insert mode). This is a rather confusing behaviour. So I have to copy the defaults win.list.keys for win.input.keys and override any customs.

I would have thought the keys for normal mode would use list keys and insert mode to use input keys.

Is there a way to set it up similar to set win.input.keys to use what I have for win.list.keys without having to duplicate it?
I.e. reuse it.

This is my working config now:

        explorer = {
          focus = 'input',
          actions = {
            go_in_if_dir = function(picker, item)
              if item.dir then
                picker:action 'confirm'
              end
            end,
          },
          win = {
            list = {

            },

            input = {
              keys = {
                ['l'] = 'go_in_if_dir', -- Same as ./custom/MiniFiles.lua

[mau-mauricelim]

After playing around with the config this is what I have in my snacks.lua:

local function get_explorer_keys()
  -- Default keys
  local list_keys = require('snacks.picker').sources.explorer.win.list.keys
  -- Override keys
  return vim.tbl_extend('force', list_keys, {
    ['l'] = 'go_in_if_dir', -- Same as ./custom/MiniFiles.lua
    ['L'] = { { 'confirm', 'close' } }, ---@diagnostic disable-line: assign-type-mismatch
    ['<CR>'] = { { 'confirm', 'close' } }, ---@diagnostic disable-line: assign-type-mismatch
  })
end

return {
  'folke/snacks.nvim',
  priority = 1000,
  lazy = false,
  ---@type snacks.Config
  opts = {
...
        explorer = {
          focus = 'input',
          actions = {
            go_in_if_dir = function(picker, item)
              if item.dir then
                picker:action 'confirm'
              end
            end,
          },
          win = {
            list = {
              keys = get_explorer_keys(),
            },
            -- There is no default Snacks.picker.explorer.win.input.keys set
            -- so the keys default to Snacks.picker.Config.win.input.keys
            -- This sets the keys for focus = 'input'
            input = {
              keys = get_explorer_keys(),
            },
          },
        },
...
}

Is this the proper way to do this?

[drowning-cat]

To be honest, duplication is not necessarily a bad thing, but you can also use vim.tbl_extend('force', base, { --[[override]] }).

[mau-mauricelim]

I have another question, how can i make enter key in insert/input mode also open the file directly?
Currently, I have to press enter twice for it to work.

I've tried the following but they didn't work too.

            input = {
              keys = {
                ['<CR>'] = { { 'confirm', 'close' }, mode = { 'n', 'i' } }, ---@diagnostic disable-line: assign-type-mismatch
                ['<CR>'] = { { 'confirm', 'confirm', 'close' }, mode = { 'n', 'i' } }, ---@diagnostic disable-line: assign-type-mismatch
                ['<CR>'] = { { 'toggle_focus', 'confirm', 'close' }, mode = { 'n', 'i' } }, ---@diagnostic disable-line: assign-type-mismatch
              },
            },

[drowning-cat]

After typing in the input?

fixed_confirm = function(picker)
  if picker:filter().pattern then
    picker:action 'confirm'
    -- stylua: ignore
    vim.defer_fn(function() picker:action 'confirm' end, 100)
  else
    picker:action 'confirm'
  end
end,

[mau-mauricelim]

Thanks!

This is what I have now

            custom_confirm = function(picker, item)
              -- If in insert mode
              if vim.fn.mode() == 'i' then
                -- Confirm removes the current search pattern and goes into normal mode
                picker:action 'confirm'
                vim.defer_fn(function()
                  if item.dir then
                    picker:action 'confirm'
                  else
                    picker:action { 'confirm', 'close' }
                  end
                end, 0)
              else
                if item.dir then
                  return picker:action 'confirm'
                else
                  picker:action { 'confirm', 'close' }
                end
              end
            end,

Is there any way to deduplicate this part:

                if item.dir then
                  return picker:action 'confirm'
                else
                  picker:action { 'confirm', 'close' }
                end

I tried putting it in a local function etc and it did not work.

[drowning-cat]

Honestly, I still don’t quite understand what the problem is. I’m a bit too lazy to dig deep into it right now, but you’ll need to create a minimal reproducible example if you want to find the exact root cause of this behavior because I can’t reproduce it on my end.

custom_confirm = function(picker, item)
  local confirm = function()
    if item.dir then
      picker:action 'confirm'
    else
      picker:action { 'confirm', 'close' }
    end
  end
  if vim.fn.mode() == 'i' then
    picker:action 'confirm'
    vim.defer_fn(confirm, 50)
  else
    confirm()
  end
end,

-- ...

['<CR>'] = { 'custom_confirm', mode = { 'i', 'n' } },

[drowning-cat]

By “minimal reproducible example,” I mean no other plugins, no unrelated configuration, and the exact steps needed to reproduce the issue (like a bug report).
