Anyway to change the lualine trouble.statusline to show workspace values instead of just buffer

[skela]

Have tried a few things, but not having any luck, can't find any examples on how to do it, just want the number of errors / warnings (perhaps even todos) for the whole workspace instead of just for the current buffer. (am using nvim lazy distro).

return {
	{
		"nvim-lualine/lualine.nvim",
		event = "VeryLazy",
		opts = function(_, opts)
			-- This doesnt seem to work even though it should
			local s = opts.sections.lualine_c[1]
			s.sources = { "nvim_workspace_diagnostic" }
			opts.sections.lualine_c[1] = s

			-- This doesnt work since i dont know the format to use 
			-- + i dont know how to avoid the existing trouble.statusline from showing up
			-- local trouble = require("trouble")
			-- local symbols = trouble.statusline({
			-- 	mode = "diagnostics",
			-- 	groups = {},
			-- 	title = false,
			-- 	filter = { range = true },
			-- 	format = "potato",
			-- 	-- format = "{kind_icon}{symbol.name:Normal}",
			-- 	hl_group = "lualine_c_normal",
			-- 	params = { sources = { "nvim_workspace_diagnostic" } }, -- this doesnt seem to do anything
			-- })
			-- table.insert(opts.sections.lualine_c, 1, {
			-- 	symbols.get,
			-- 	cond = symbols.has,
			-- })

			-- This works, but it doesnt have the nice trouble UI + i dont know how to remove the existing status line
			-- vim.list_extend(opts.sections.lualine_b, {
			-- 	{ "diagnostics", sources = { "nvim_workspace_diagnostic" } },
			-- })
			opts.sections.lualine_y = { "encoding" }
			opts.sections.lualine_z = { "location", "progress" }
			return opts
		end,
	},
}

This here gets me very close to what I want, the only thing ive lost is the code context stuff (so class name / method) that comes with the default lualine from lazynvim , which i believe is via aerial (i could be wrong).

Adding aerial to my config does not make it appear though. So getting closer

Screenshot here is from the default config, where it shows diagnostics for just the file:

Here is what the config below gives me (workspace diagnostics works, but lost the class / method context):

return {
	{
		"nvim-lualine/lualine.nvim",
		event = "VeryLazy",
		opts = function(_, opts)
			local icons = LazyVim.config.icons
			opts.sections.lualine_c = {
				LazyVim.lualine.root_dir(),
				{
					"diagnostics",
					sources = { "nvim_workspace_diagnostic" },
					symbols = {
						error = icons.diagnostics.Error,
						warn = icons.diagnostics.Warn,
						info = icons.diagnostics.Info,
						hint = icons.diagnostics.Hint,
					},
				},
				{ "filetype", icon_only = true, separator = "", padding = { left = 1, right = 0 } },
				{ LazyVim.lualine.pretty_path() },
				{
					"aerial",
					sep = " ", -- separator between symbols
					sep_icon = "", -- separator between icon and symbol

					-- The number of symbols to render top-down. In order to render only 'N' last
					-- symbols, negative numbers may be supplied. For instance, 'depth = -1' can
					-- be used in order to render only current symbol.
					depth = 5,

					-- When 'dense' mode is on, icons are not rendered near their symbols. Only
					-- a single icon that represents the kind of current symbol is rendered at
					-- the beginning of status line.
					dense = false,

					-- The separator to be used to separate symbols in dense mode.
					dense_sep = ".",

					-- Color the symbol icons.
					colored = true,
				},
				-- { "navic", color_correction = "dynamic" },
			}
			opts.sections.lualine_y = { "encoding" }
			opts.sections.lualine_z = { "location", "progress" }
			return opts
		end,
	},
}

The number of diagnostics does not come from trouble, that's a builtin of lualine.
The code context however, IS trouble. Not aerial.

folke's answer led me to the solution + this url here: https://github.com/LazyVim/LazyVim/blob/d1529f650fdd89cb620258bdeca5ed7b558420c7/lua/lazyvim/plugins/ui.lua#L93

Working solution:

return {
	{
		"nvim-lualine/lualine.nvim",
		event = "VeryLazy",
		opts = function(_, opts)
			local icons = LazyVim.config.icons
			local trouble = require("trouble")
			local symbols = trouble.statusline({
				mode = "lsp_document_symbols",
				groups = {},
				title = false,
				filter = { range = true },
				format = "{kind_icon}{symbol.name:Normal}",
				hl_group = "lualine_c_normal",
			})
			opts.sections.lualine_c = {
				LazyVim.lualine.root_dir(),
				{
					"diagnostics",
					sources = { "nvim_workspace_diagnostic" },
					symbols = {
						error = icons.diagnostics.Error,
						warn = icons.diagnostics.Warn,
						info = icons.diagnostics.Info,
						hint = icons.diagnostics.Hint,
					},
				},
				{ "filetype", icon_only = true, separator = "", padding = { left = 1, right = 0 } },
				{ LazyVim.lualine.pretty_path() },
				{
					symbols.get,
					cond = symbols.has,
				},
			}
			opts.sections.lualine_y = { "encoding" }
			opts.sections.lualine_z = { "location", "progress" }
			return opts
		end,
	},
}
