I cannot get the null-ls prettier to work

[wakywayne]

I've gotten everything working with no errors however I can't seem to figure out how to get prettier to work I can't run the vim formatting command that you use in the null-ls video. The other thing I am struggling to figure out is how to do find and replace in vim. If you can help me with these issues I would really appreciate it.

I installed everything with mason and when I use the NullLsInfo command it shows me that prettier is active

null-ls.lua:

local null_ls_status_ok, null_ls = pcall(require, "null-ls")
if not null_ls_status_ok then
	return
end

-- https://github.com/jose-elias-alvarez/null-ls.nvim/tree/main/lua/null-ls/builtins/formatting
local formatting = null_ls.builtins.formatting
-- https://github.com/jose-elias-alvarez/null-ls.nvim/tree/main/lua/null-ls/builtins/diagnostics
local diagnostics = null_ls.builtins.diagnostics

null_ls.setup({
	debug = false,
	sources = {
		formatting.prettier.with({ extra_args = { "--no-semi", "--single-quote", "--jsx-single-quote" } }),
		formatting.black.with({ extra_args = { "--fast" } }),
		formatting.stylua,
    -- diagnostics.flake8
	},
})

-- null_ls.setup({
--     sources = {
--         null_ls.builtins.formatting.stylua,
--         null_ls.builtins.diagnostics.eslint,
--         null_ls.builtins.completion.spell,
--     },
-- })

I do not understand why we put some things in the servers list and not others, if someone could explain that'd be great

Mason.lua:

local servers = {
	"sumneko_lua",

	 "html",

local settings = {
	ui = {

	},
	log_level = vim.log.levels.INFO,
	max_concurrent_installers = 4,
}

require("mason").setup(settings)
require("mason-lspconfig").setup({
	ensure_installed = servers,
	automatic_installation = true,
})

local lspconfig_status_ok, lspconfig = pcall(require, "lspconfig")
if not lspconfig_status_ok then
	return
end

local opts = {}

for _, server in pairs(servers) do
	opts = {
		on_attach = require("user.lsp.handlers").on_attach,
		capabilities = require("user.lsp.handlers").capabilities,
	}

	server = vim.split(server, "@")[1]

	local require_ok, conf_opts = pcall(require, "user.lsp.settings." .. server)

I figured it out. The names of mason and the actual lsp don't always line up. You must go here
to get the correct naming to put in the mason file.

Sweet. Thanks for the heads up!
