Linting works after activating the LSP twice using Autocommand FileType.

nvim-lspconfig version(commit hash): 47d80fa334aff1fdf720ebd0f3efb1f19230788c
What language server (If the problem is related to a specific language server): clangd, ccls, pyright
Can you reproduce this behavior on other language server clients (vscode, languageclient-neovim, coc.nvim, etc.): No
Can you reproduce this behavior on other language servers offered in the nvim-lspconfig repo? (pyls -> pyright): Yes
Is the problem isolated to a particular language server: No
Operating system/version: Manjaro Linux. 5.10.56

Installed nvim-lspconfig via pathogen

When requesting the Lspconfig for a filetype via

autocmd FileType cpp lua require('lspconfig').clangd.setup{}

it does not activate linting. Only after the autocommand is called twice will the linting work.

autocmd FileType cpp lua require('lspconfig').clangd.setup{}
autocmd FileType cpp lua require('lspconfig').clangd.setup{}

Yet when calling the require command without the FileType autocommand, it activates linting:

lua require('lspconfig').clangd.setup{}

Temporary solution

I found a workaround that activates the lsp depending on the filetype.

if &filetype ==# "cpp"
    lua require('lspconfig').clangd.setup{}
endif

How to reproduce the problem from neovim startup

Install:

nvim-lspconfig
clang
pyright Open a file ending in either: .cpp or .py

Actual behaviour

LSP does not show linting

Expected behaviour

Have LSP show linting

Minimal init.vim or init.lua and code sample

" When executing via Autocommand, the 'require' needs to be called twice.
augroup CPP
    autocmd!
    autocmd FileType cpp lua require('lspconfig').clangd.setup{}
    "autocmd FileType cpp lua require('lspconfig').clangd.setup{}
augroup END

augroup PY
    autocmd!
    autocmd FileType python lua require('lspconfig').pyright.setup{}
    "autocmd FileType python lua require('lspconfig').pyright.setup{}
augroup END

" Only need to call 'require' once when not executing via an autocommand

" lua require('lspconfig').clangd.setup{}
" lua require('lspconfig').pyright.setup{}

Python Code for testing

The LSP should show '"var" is not defined'

var

C++ Code for testing

The LSP should show 'Use of undeclared identifier 'endl'; did you mean 'std::endl'? (fix available)

#include <iostream>

int main()
{
    cout << "hello" << endl;
}

You are lazy loading a lazy load. Your filetype autocommand is calling a function which maps a filetype autocommand which can't be called because the buffer filetype trigger was already called (and which mapped it).

I see. Thanks for the quick response. There is a lot for me to learn.

Those who use lazy.nvim could face the same problem https://github.com/folke/lazy.nvim/issues/880 for the same reason
