How to customise float window?

[augustocdias]

How do I change the highlights from the float windows?

I would like to change the background. I'd like to change the color and remove the transparency.

There are three categories of floating windows that have config options. There's the "form" floats that open when you're launching or editing a task, the "confirm" float which only shows up when saving a task, and the "task_win" task output float that is opened from the "open float" action.

All of these are configured in the call to setup, and I believe the options you are looking for is to set winblend = 0 (see :help winblend) and winhighlight = "NormalFloat:MyCustomHighlight" (see :help winhighlight).

require("overseer").setup({
  form = {
    win_opts = {
      winblend = 0,
      winhighlight = "NormalFloat:MyCustomHighlight",
    },
  },
  confirm = {
    win_opts = {
      winblend = 0,
      winhighlight = "NormalFloat:MyCustomHighlight",
    },
  },
  task_win = {
    win_opts = {
      winblend = 0,
      winhighlight = "NormalFloat:MyCustomHighlight",
    },
  },
})

Isn't the preview window supposed to accept custom options too?

overseer.nvim/lua/overseer/task_list/sidebar.lua

Lines 97 to 107 in 2fb1794

	local winid = vim.api.nvim_open_win(task:get_bufnr(), false, {
	relative = "editor",
	border = "rounded",
	row = 1,
	col = col,
	width = width,
	height = vim.api.nvim_win_get_height(0),
	style = "minimal",
	})
	vim.api.nvim_win_set_option(winid, "previewwindow", true)
	vim.api.nvim_win_set_option(winid, "winblend", 10)

It seems winblend, border, etc are all hardcoded.

The "p" to preview is intended just for previewing the output. If you want your cursor to focus the window, use <C-f> to "open float" instead.

You're likely entering insert mode because you have an autocmd set up to do startinsert on BufEnter or some other event (it's recommended in the vim help docs, so a lot of people have that autocmd). If you can find out what it is, I might be able to give you some pointers on things you could adjust.

The preview window opts were an oversight. Should be fixed now

You're completely right. I have a start insert for when the buffer is a terminal.

Do you set a buftype for the float or is there anything I can check to avoid this behavior for overseer popups?

I think the issue is that the autocmd event is running on BufEnter, BufWinEnter, or similar and it's triggering startinsert even though you're not in the terminal buffer.

I pushed up a change that opens the preview window with noautocmd = true, which might fix your issue. If not, I recommend some version of the config below:

vim.api.nvim_create_autocmd("TermOpen", {
  desc = "Auto enter insert mode when opening a terminal",
  pattern = "*",
  group = aug,
  callback = function()
    -- You could even wrap this in vim.defer_fn() if there's a possibility that
    -- the terminal loses focus immediately
    if vim.api.nvim_buf_get_option(0, "buftype") == "terminal" then
      vim.cmd([[startinsert]])
    end
  end,
})
