Show file path in the winbar

init.lua

vim.o.winbar = "%{%v:lua.require'nvim.utils.nvim.winbar'.eval()%}"

winbar.lua

local M = {}

vim.api.nvim_set_hl(0, 'WinBarPath', { bg = '#dedede', fg = '#363636' })
vim.api.nvim_set_hl(0, 'WinBarModified', { bg = '#dedede', fg = '#ff3838' })

function M.eval()
    local file_path = vim.api.nvim_eval_statusline('%f', {}).str
    local modified = vim.api.nvim_eval_statusline('%M', {}).str == '+' and '⊚' or ''

    file_path = file_path:gsub('/', ' ➤ ')

    return '%#WinBarPath#'
     .. file_path
     .. '%*'
     .. '%#WinBarModified#'
     .. modified
     .. '%*'
end

return M

How do we add a space before "modified"?

Just adding ' ' ..?

.. ' ' .. modified

I have changed some stuff, added "WinbarFiletypeExclude" and Last modification date, etc. Thanks for sharing your knowledge!

Nice

Thanks for this and your videos!
I've found the following function helpful

local function join_status_line(input, highlight, item)
  return input .. '%#' .. highlight .. '#' .. item .. '%*'
end

function M.eval()
    local winbar = ''
    -- do stuff.........
      winbar = join_status_line(winbar, 'WinBarPath', file_path)
      winbar = join_status_line(winbar, 'WinBarModified', modified)

     return winbar
end
