My goal is to automatically close the environment while editing a tex file. There was an issue for vimtex asking for basically what I want to achieve. They achieve it using snippets as mentioned there.

The problem is, I have no idea how to set it up. I’ve never used snippets in nvim. I have vim-vsnip and cmp-vsnip installed as it was needed for another plugin to work. Is it possible to implement this using those?

It can be noted that in vimtex, an environment can be closed by typing ]] which is a mapping of vimtex-delim-close. I basically want to emulate the behavior in VS Code using LaTeX Workshop. It auto-closes the environment, adds an indented line in the middle, and moves the cursor there.

If anyone has any other ideas about doing this without snippets, that’s welcome too.
