vim-plug VS copilot.vim

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.

I use copilot in neovim[1]. It was remarkably simple to get installed. Highly recommend

[1]: https://github.com/github/copilot.vim

I use Plug 'tpope/vim-markdown' and markdown fenced codeblocks fairly extensively, and recently installed Copilot.vim.

Anyways. Yes, neovim has AI integration like copilot ( https://github.com/github/copilot.vim ) and chatgpt ( https://github.com/jackMort/ChatGPT.nvim )

I do think VSCode is a great tool and I recommend it frequently to people, but I still want to set the record straight here. Yes, vim is obviously limited in the sense that as a CLI app it doesn't draw it's own PDF or HTML windows, that's fair. But it can remote control your favorite PDF viewer or browser for roughly the same functionality. I'm currently writing my thesis using vimtex and it's quite smooth. And all the other stuff you mention is implemented quite competently by various plugins like vim-fugitive, coc.nvim, vimspector and copilot.vim.
