nvim VS vim-plug

So I wonder, how my config could be wrong if everything was ok ? I've always thought I could have the structure I want as long as I require files/plugins correctly, and as I saw this in many people configs I thought it was not a bad practice, more a way to have a clean config, but well, maybe I'm wrong.

There's things that seem strange to me in your plugins.lua. Not sure this is the problem but I've never seen use({something}) like this (I mean with parenthesis). Finally checking if packer exist and install it if necessary becomes useless if you install it later with packadd. There's a quite big config and I think you know what you're doing but seeing these I prefer showing how I did for my config. You can check this capture too if you want.

Nice ! I was searching for something like this. I've been trying to do the same but after 2 hours and so much pain in the config I git restore my config ^

I also hard times moving away from vimL and Coc at the begining but when I realised that LsPinstall/LspConfig just install and configure every lsp servers correctly (you also can reload them once updated if you read a bit their README) I stopped worrying and enjoyed a nvim that never as been so fast and powerful. I can share my config but you surely have better ones in the first link I gave above.

vim-plug

Did you really install VimTeX? Did you run :PlugInstall? Ensure you installed and set up vim-plug correctly (https://github.com/junegunn/vim-plug). If VimTeX is installed, it should be installed to '~/.vim/plugged', thus you can open a terminal, then cd ~/.vim/plugged/vimtex and you should find the files there.

If you're determined to use vim for some reason, I'd suggest checking out vim-plug: https://github.com/junegunn/vim-plug. Quite useful for installing and maintaining all of the plugins that you're going to need to get vim to provide even a subset of the features offered by modern editors.

I encourage you to add plugins to your vim (tip: use vim-plug). Use vimawesome.com for inspiration.

Personally, I like https://github.com/junegunn/vim-plug

But the plugin manager https://github.com/junegunn/vim-plug can also install from offline sources, without accessing Github:

To get started, simply install the plugin using your favorite plugin manager, such as vim-plug or packer.nvim. You can find detailed installation instructions in the README.

Not sure if Vundle did anything particularly fancy, but I'm using vim-plug [0] and have no complaints. It stays out of my way to the point that I had to look at my .vimrc just now to make sure that's what I was using.

I chose to move on to vim-plug and can report it was a simple switch from Vundle.
