What plugin can be used to achieve this effect?

[jonahfang]

[jonahfang]

I use akinsho/bufferline.nvim .

[catgoose]

That would be heirline. Heirline starts with nothing and you have to build your own statusline/winbars. It takes a little work to get setup, but you can really make it your own. For example, though it's hard to see in the screenshot there is an indicator at the bottom showing how far you have scrolled down a buffer:

That indicator is only shown on the active window.

[jonahfang]

Thanks for reply. Why do you not use plugin like 'akinsho/bufferline.nvim'? I want to see all buffers opened:

[catgoose]

Because I want to see the file name of the buffer in the current window and not all the buffers that I have open. I don't generally close buffers, and when I do I close all of them at once using bufdelete plug-in.

It's my opinion that it's a mistake to treat buffers as tabs the way bufferline shows them. They are the contents of a file that can be mounted into a window. They are not tabs. That's just my opinion of course.

[jonahfang]

Good! You make sense, but I need time to accept your point of view.

[catgoose]

I would recommend reading this if you haven't already:

Thank you very much, you change my mind. I have just remove 'bufferline', and use 'heilline'+'lualine' (heiline just as winbar):

The effect:

I lost the grey background of winbar filename, can you help me?

[catgoose]

I manually set the colors in colors.lua so make sure you are using the correct reference. You may have to verify the colors are correct. I can take a better look in the morning.

I sovled. Your nvim configuration is awesome.

Thanks I really appreciate that! I need to do a few tweaks here and there but I find it useful for work.

The above problem only exists in MacOS iTerm2, in WezTerm it is ok.
