Snacks Exporer misrepresents itself as floating window and breaks tmux-nvim navigation

[rudenkornk]

I have a LazyVim setup combined with tmux.nvim plugin with recommended settings.
<C-h> moves focus to the left, <C-l> to the right etc.
This worked fine with Neotree correctly changing focus and resizing windows.
However this does not work with Snacks Explorer: when trying to change focus from explorer to main neovim window (arrow 1), focus instead changes to another tmux pane (arrow 2)

I suppose this happens because this func in tmux.nvim recognizes Explorer is a floating window and thus navigation passes to tmux panes here.

What do you want to ask?
This won't be fixed. The Snacks Explorer consists of multiple windows:

• container
  • input
  • list (focused by default)
  • preview

All of these windows are floating, except for the container.

Yes, but the test is not about <C-w>h/l. I want you to refocus the explorer and then try using the tmux.nvim navigation keys with the same explorer (don't close it).

[rudenkornk]

Oh, ok.
Tried it, did not work, tmux navigation worked as previous (incorrectly).

[drowning-cat]

Thanks, sad.

You can override M.is_nvim_float:

require('tmux.wrapper.nvim').is_nvim_float = function()
  if Snacks then
    local is_explorer = vim.iter(Snacks.picker.get { source = 'explorer' }):any(function(picker) ---@param picker snacks.Picker
      return picker:is_focused()
    end)
    if is_explorer then
      return false
    end
  end
  return vim.api.nvim_win_get_config(0).relative ~= ""
end

Thanks, probably this will work. Though pattern should match only "falsy" floats of snacks (i.e. file picker is actually floating, so it should not be included)

[rudenkornk]

Duh... Snacks Explorer and Snacks File Picker both have the same name 😮‍💨

[rudenkornk]

I actually like your solution much better since it is more stable. Any thoughts how to specifically distinguish between explorer and file picker? (I know they are basically the same, but still...)

[drowning-cat]

• But is it even possible to navigate when Files picker is open?
• I will update the code if needed.

Some thoughts: based on @fastnded W/A created one, that works for me:

opts = {
  picker = {
    actions = {
      win_right = function(picker)
        vim.api.nvim_command("wincmd l")
      end,
    },
    sources = {
      explorer = {
        win = {
          input = {
            keys = {
              ["<C-l>"] = { "win_right", mode = { "i", "n" } }, -- W/A for tmux navigation
            },
          },
          list = {
            keys = {
              ["<C-l>"] = { "win_right", mode = { "i", "n" } }, -- W/A for tmux navigation
            },
          },
        },
      },
    },
    win = {
      input = {
        keys = {
          ["<C-j>"] = false, -- disable, conflicts with tmux navigation
          ["<C-k>"] = false, -- disable, conflicts with tmux navigation
        },
      },
      list = {
        keys = {
          ["<C-j>"] = false, -- disable, conflicts with tmux navigation
          ["<C-k>"] = false, -- disable, conflicts with tmux navigation
        },
      },
    },
  },
}

This of course will only work if Explorer is located on the left.
