Installation

The plugin requires at least nvim 0.10.

-- lazy.nvim
{ "chrisgrieser/nvim-dr-lsp" },

-- packer
use { "chrisgrieser/nvim-dr-lsp" }

There is no .setup call for this plugin. Just add the components to your statusline.

Highlights of definitions and references

• Definitions are under-dashed, references are under-dotted.
• These are set up automatically for you as soon as the buffer is attached to an LSP client.
• To disable the highlights feature, set vim.g.dr_lsp_no_highlight = true before loading the plugin.
• The time for the highlights to show up depends on the updatetime option. It's recommended to set it to something like 300 ms.

Definition and reference count in the statusbar

Definitions and references inside current buffer:

LSP: 2D 6R

Definitions or references outside current buffer

LSP: 1(2)D 4(10)R

• 1 definition in the current buffer
• 2 definitions in the workspace
• 4 references in the current buffer
• 10 definitions in the workspace

-- adding the component to lualine.nvim
{
	sections = {
		lualine_c = {
			{ require("dr-lsp").lspCount },
		},
	}
}

There are no built-in options to format the components, since formatting can already be done with most statusline plugins. With Lualine, for example, you can use the fmt option:

lualine_c = {
	{ 
		require("dr-lsp").lspCount, 
		-- remove the letters from the component
		fmt = function(str) return str:gsub("[RD]", "") end,
	},
},

Alternatively, require("dr-lsp").lspCountTable() returns the lspCount information as lua table for custom formatting:

{
	file = {
		definitions = 1,
		references = 4,
	},
	workspace = {
		definitions = 2,
		references = 10,
	},
}
