How to enable *only* treesitter scope underline?

[ferdinandrau]

I currently use these Vim options:

vim.o.list = true
vim.o.listchars = "tab:› ,lead:·,trail:·,nbsp:␣,extends:…"

I would like to have no indent guides whatsoever but show the (exact) scope start and end underlines. Is this possible using this plugin? Couldn't get it to work, what combination of options is needed?

Setting :help ibl.config.indent.char to "" should get you that.

Thanks, the one issue with this though is that the fill chars in the current scope that are in the place where the indent guides would be still get highlighted.

There is no built-in way to disable the scope highlight.
You can use a custom hook to remove it. Something like this should work.

local hooks = require "ibl.hooks"
hooks.register(hooks.type.VIRTUAL_TEXT, function(_, _, _, virtual_text)
    return vim.tbl_map(function(vt)
        if type(vt[2]) == "table" then
            vt[2] = vim.tbl_filter(function(name)
                return not string.find(name, "scope")
            end, vt[2])
        end
        return vt
    end, virtual_text)
end, {})
