Completion Function Fails in neovim configured by Lua

[DowneyFlyfan]

Here is my lsp.lua:

-- Mason Settings

vim.keymap.set("n", "<space>e", vim.diagnostic.open_float, { noremap = true, silent = true })
vim.keymap.set("n", "[d", vim.diagnostic.goto_prev, { noremap = true, silent = true })
vim.keymap.set("n", "]d", vim.diagnostic.goto_next, { noremap = true, silent = true })
vim.keymap.set("n", "<space>q", vim.diagnostic.setloclist, { noremap = true, silent = true })

On_attach = function(_client, bufnr)
	require("lsp_signature").on_attach({

	vim.api.nvim_create_autocmd("BufWritePre", {

		callback = function(args)
			local filetype = vim.api.nvim_buf_get_option(args.buf, "filetype")

				vim.lsp.buf.format({ bufnr = args.buf })

	})
end

require("mason-nvim-dap").setup({

require("mason-tool-installer").setup({

	},

	auto_update = true,
	run_on_start = true,
	start_delay = 500,
	debounce_hours = 5,
	integrations = {

require("Languages.python")

require("Languages.lua_config")

Here is my Languages.verilog.lua:

-- LSP config for svls
vim.lsp.config("svls", {
	on_attach = On_attach,
	capabilities = Capabilities,
	settings = {},
})

Here is my nvim-cmp":

local has_words_before = function()
	unpack = unpack or table.unpack
	local line, col = unpack(vim.api.nvim_win_get_cursor(0))
	return col ~= 0 and vim.api.nvim_buf_get_lines(0, line - 1, line, true)[1]:sub(col, col):match("%s") == nil
end

local luasnip = require("luasnip")
local cmp = require("cmp")

cmp.setup({
	snippet = {
		expand = function(args)
			require("luasnip").lsp_expand(args.body) -- For `luasnip` users.
		end,
	},
	window = {
		completion = cmp.config.window.bordered(),
		documentation = cmp.config.window.bordered(),
	},
	mapping = cmp.mapping.preset.insert({
		-- ["<C-b>"] = cmp.mapping.scroll_docs(-4),
		-- ["<C-f>"] = cmp.mapping.scroll_docs(4),
		-- ["<C-Space>"] = cmp.mapping.complete(),
		["<C-q>"] = cmp.mapping.abort(),
		["<CR>"] = cmp.mapping.confirm({ select = true }),

		["<Tab>"] = cmp.mapping(function(fallback)
			if cmp.visible() then
				cmp.select_next_item()
			elseif has_words_before() then
				cmp.complete()
			else
				fallback()
			end
		end, { "i", "s" }), -- i - insert mode; s - select mode
		["<S-Tab>"] = cmp.mapping(function(fallback)
			if cmp.visible() then
				cmp.select_prev_item()
			elseif luasnip.jumpable(-1) then
				luasnip.jump(-1)
			else
				fallback()
			end
		end, { "i", "s" }),
	}),

	formatting = {
		fields = { "abbr", "menu" },

		-- customize the appearance of the completion menu
		format = function(entry, vim_item)
			vim_item.menu = ({
				nvim_lsp = "[Lsp]",
				luasnip = "[Luasnip]",
				buffer = "[File]",
				path = "[Path]",
			})[entry.source.name]
			return vim_item
		end,
	},

	-- Set source precedence
	sources = cmp.config.sources({
		{ name = "nvim_lsp" },
		{ name = "luasnip" },
		{ name = "vimtex" },
		{ name = "buffer" },
		{ name = "path" },
	}),
})

Even if I delete verible, svls still fails on completion. Does anyone have the same experience?

[DowneyFlyfan]

Come on, nobody has this problem??

Unfortunately, svls doesn't support completion feature.

But completion feature is demonstrated in your readme(σﾟ∀ﾟ)σ

OK. It seems to be confusing. It is keyword-based completion provided another plugin.

Got it. Thank you for your interpretation.

Can you please tell me which plugin is that?

[sevenninesixthree]

I think its provided by any snip plugin and related snips written by hand.
