How to show file particular path only on unfocused windows

[XXiaoA]

Assuming that we have three windows in a tab: ~/a ~/b/file ~/c/file, we focus on the windows ~/a and its winbar show symbol as normal. But I want other two window show b/file and c/file in winbar instead of showing symbol. How can we do that?

You can create your own sources by wrapping existing sources and let the custom sources return empty lua table when the cursor is not at the window the dropbar instance is attached to.

Thx! But I'm confused about how to change the bar's source when we are about to leave a window. Before entering a new window, we ought to update the current winbar to only one source particular_path, I think.

Now I can create a source to show different content between focused window and unfocused windows.

    local source = {
        get_symbols = function(buf, win, cursor)
            if vim.api.nvim_get_current_win() ~= win then
                return {
                    bar.dropbar_symbol_t:new({
                        name = "Unfocused",
                        name_hl = "Title",
                    }),
                }
            end
            return { 
                    bar.dropbar_symbol_t:new({
                        name = "Focused",
                        name_hl = "Title",
                    }),
                 }

        end,
    }

Then we can set opt.bar.sources = { source }

The problem what I met is that in a focused window, we have loads of sources like path lsp. But in unfocused window, we have one source p_path only. I don't know how to do it. I tried use a function as opts.bar.sources's value, like

sources = function(buf, win)
    if win == current_win then
         return { path, lsp }
    else
         return { p_path }
    end
end

But it doesn't work. Because function is triggered when a new winbar is created only. Do u have any idea? @Bekaboo

@XXiaoA You should create a source that returns an empty table when the source is requested to return symbols for a window that is not the current window, instead of trying to change the source when you switch the window.

okay, i got it. Thx!
