Help with trouble.nvim - I want to cycle through modes (lemmy.world)

As the title suggests, I want to set something up so that while trouble is_open(), I have a keyboard shortcut that cycles through the various modes listed at https://github.com/folke/trouble.nvim/tree/main#commands.

I see how I can assign shortcuts to jump directly to the different modes, but I want to remember only one shortcut.

Writing a bit of lua to do this is easy enough, but I can't find any way to see what mode it's currently in, in order to write some function that toggles to the next one.

Is there any way to accomplish this?

Bonus question: Is there any way to get trouble to display on screen what mode it's currently in? Such as at the top or bottom of the trouble panel.

I don’t know any specifics about trouble, but would it be good enough to just track the current mode in your own global option/variable whenever you toggle it with your shortcut?

If not I‘d start by taking a look at the trouble source code.

For the sake of sharing... I took your idea and found this worked just fine:

TroubleMode = "workspace_diagnostics"

local function cycle_trouble_mode()
	local trouble = require("trouble")

	local modes = {
		"document_diagnostics",
		"workspace_diagnostics",
		"lsp_references",
		"lsp_definitions",
		"lsp_type_definitions",
		"quickfix",
		"loclist",
	}

	if trouble.is_open() then
		local function get_next_mode(mode)
			local next_index = 1
			for i = 1, #modes do
				if modes[i] == mode then
					next_index = i == #modes and 1 or i + 1
				end
			end
			return modes[next_index]
		end

		TroubleMode = get_next_mode(TroubleMode)
		trouble.toggle(TroubleMode)
	end
end

I did end up looking at the code a bit and couldn't find what I wanted. But what you suggest is a good idea. I may give that a try.
