Can I remove this fillchars opt?

[yoshiya0503]

If we use this option (remove all vert and horiz lines, and put status line to bottom)

vim.opt.fillchars = {
  horiz     = " ",
  horizup   = " ",
  horizdown = " ",
  vert      = " ",
  vertleft  = " ",
  vertright = " ",
  verthoriz = " ",
  eob       = " ",
}
vim.o.laststatus = 3

I could not remove separator between diagnosis and outline of Trouble.

But I found fillchars settings at Trouble (trouble/view/window.lua), and I remove fillchars option from this minimal.wo, works very fine.

Do you have any other idea, remove the separator?

do you have any idea?

finally I found the perfect answer.

require("trouble").setup {
  win = {
    wo = {
      fillchars = ""
    }
  },
}
