Can't put floating option to the right.

[fnacarellidev]

Here's my current nvim-tree.lua config file
require("nvim-tree").setup({ view = { side = "right", float = { enable = true, quit_on_focus_loss = false, }, mappings = { list = { { key = "u", action = "dir_up" }, { key = "t", action = "cd" }, }, }, }, renderer = { highlight_opened_files = "all", indent_markers = { enable = true, }, }, })
I thought that if I did that the nvim-tree would float and would be at the right of my screen, but it doesn't, anyone knows why?

require("nvim-tree").setup {
  view = {
    side = "right",
    float = {
      enable = true,
      quit_on_focus_loss = false,
    },
  },
}

view.side does not apply to floating windows. You can set all your floating window parameters via view.float.

See :help nvim_open_win for all the options. anchor might be the one you are looking for.

Thank you, do you have any advice on how to do this configuration for nvim-tree?

[alex-courtis]

Unfortunately I'm not familiar with nvim_open_win

If you can't achieve the behaviour you want with a static table, you can set open_win_config to a function which can dynamically calculate the config.

@fnacarellidev Did you manage to figure this out? It seems when I do the following the anchor doesn't change (or perhaps I'm misunderstanding the option). I am also trying to move the floating window to the right.

float = {
  enable = true,
  open_win_config = {
    anchor = "NE"
  }
}

Take a look a @kryzar 's excellent solution:

#1538 (comment)

That allows exact positioning of the floating window.

Hopefully @kryzar will add his Recipe to the wiki ;)

This looks great! But is a bit more involved, was hoping anchor would just fix it to the right. Is there a reason that attribute doesn't seem to work?

Unfortunately that's outside the scope of nvim-tree, as the options are simply passed through. It's also very far outside of my knowledge.

I really shouldn't be credited for this! I will post the recipe, but all I did was using @davidsierradz's solution.

I modified @kryzar solution to pin the floating window to the upper right

local WIDTH_RATIO = 0.3
local HEIGHT_RATIO = 0.8
local OFFSET = 3

require('nvim-tree').setup({
  view = {
    float = {
      enable = true,
      open_win_config = function()
        local screen_w = vim.opt.columns:get()
        local screen_h = vim.opt.lines:get() - vim.opt.cmdheight:get()
        local window_w = screen_w * WIDTH_RATIO
        local window_h = screen_h * HEIGHT_RATIO
        local window_w_int = math.floor(window_w)
        local window_h_int = math.floor(window_h)

        -- adjust for the offset
        local col_right_aligned = screen_w - window_w_int - OFFSET
        local row_offset = OFFSET - 3


        return {
          border = 'rounded',
          relative = 'editor',
          row = row_offset,
          col = col_right_aligned,
          width = window_w_int,
          height = window_h_int,
        }
      end,
    },
    width = function()
      return math.floor(vim.opt.columns:get() * WIDTH_RATIO)
    end,
  },
})

Many thanks!
