lsp ?

I am assuming you dont try out new langs on a daily and dont need mason.

1. First ensure you have downloaded the lsp for your lang of choice.

2. Then, go to: https://github.com/...lspconfig.nvim go into the /lsp directory and find the file corresponding to the name of your lsp. So for rust you would find the rust-analyzer file for go you would find gopls and so on.

3. Then copy the contents of that file into ~/.config/nvim/lsp/<YOUR_FILE_HERE> name this file accoring to the language its for (rust.lua, go.lua, etc,.).

4. Then go into your init.lua, (this is the entry point for nvim) usually at ~/.config/nvim/init.lua and write:

1vim.lsp.enable({
2    'rust'
3    -- 'lua' THESE ARE THE FILE NAMES IN THE LSP DIRECTORY
4    -- 'go'
5})

then below that add:

 1-- LspAttatch just means that whenever a lsp is being used
 2--run the stuff inside this block
 3vim.api.nvim_create_autocmd("LspAttach", {
 4    group = vim.api.nvim_create_augroup("lsp", { clear = true }),
 5    callback = function(args)
 6        local client = assert(vim.lsp.get_client_by_id(args.data.client_id))
 7        local bufnr = args.buf
 8        --this is a thing for specific lsp i lwk dont know why i even have this
 9        if client then client.server_capabilities.semanticTokensProvider = nil end
10
11        local function map(mode, lhs, rhs, opts)
12            opts = opts or {}
13            opts.buffer = bufnr
14            vim.keymap.set(mode, lhs, rhs, opts)
15        end
16        -- START: This is where you define the keymaps, 
17        --these are technicaly all set by default
18        --but I find setting then with somthing
19        --comon like "gr" and then the specific command 
20        --makes it easier to remmeber. 
21        -- there are more but you can figure that out yourself.
22        -- Also shift + k lets you see documentation of the thing
23        --your cursor is on
24        map('n', 'grD', vim.lsp.buf.declaration)
25        map('n', 'gri', vim.lsp.buf.implementation)
26        map('n', 'grd', vim.lsp.buf.definition)
27        map('n', 'grn', vim.lsp.buf.rename)
28        -- END 
29
30        -- START: This block lets you format on save
31        vim.api.nvim_create_autocmd("BufWritePre", {
32            buffer = bufnr,
33            callback = function()
34                vim.lsp.buf.format { async = false, id = client.id }
35            end,
36        })
37        -- END
38    end,
39})
40

you now should be getting lsp working!
