nvim-tree resizes other windows after opening

[alloc33]

I have an issue with preserving window proportions. If I have one or more horizontal splits - it doesn't work. For example I have terminal in the bottom (:term://zsh or ToggleTerm terminal). So nvim-tree keeps resize my splits igoring 'preserve_window_proportions' property.

Is there any way to fix that?

Unfortunately :help nvim-tree.view.preserve_window_proportions only applies to windows that nvim-tree open, rather than the nvim-tree window itself.

Resizing after split is actually a vim option: :help 'equalalways' and out of nvim-tree's control. Try :set noequalalways

setting equalalways=true unfortunally doesn't help

Suggestion: try to replicate the behaviour you desire without nvim-tree.

Create a "fake nvim-tree" window with, say width 30 and try to produce your desired behaviour with manual window opens etc.

On WinNew

  set winfixwidth
  set winfixheight

Or open_window in lua/nvim-tree/view.lua should be rewritten like this.

local function open_window()
  if M.View.float.enable then
    vim.api.nvim_open_win(0, true, open_win_config())
  else
    -- vim.api.nvim_command "vsp"
    -- M.reposition_window()
    local width = get_width()
    vim.api.nvim_command(('vert topleft %s split'):format(width))
  end
  setup_tabpage(vim.api.nvim_get_current_tabpage())
  set_window_options_and_buffer()
end

This works to preserve window sizes when I open nvim-tree with NvimTreeToggle. But the moment I close nvim-tree, the window sizes are wrongly resized to "default" sizes.
