expanding parentheses gives undesirable indentation in neovim

Question

This post is not about curly brackets. It is about parentheses.

I couldn't find a solution on how to expand parentheses with my ideal indentation.

What happens now with expanding parentheses

I have delimitMate installed, but I don't think this is delimitMate's problem because it produces the same output without delimitMate. Yes, I experimented it.

The closest I've gotten was with filetype indent off, which successfully aligns the closing parenthesis with the opening one. However, the cursor's position ends up where I don't want it to be.

Ideally, I want a solution with delimitMate installed, but I think a solution without delimitMate will be a good foundation to solve this with delimitMate. So, I want to hear any solution to this with or without delimitMate.

Answer 1

I kind of solved the problem.(There might be a better way.)

Here is what I did as a Rust programmer.

1. I installed rust.vim plugin.
2. I found a pending pull request for the plugin.
3. I added the code manually from that pull request to see how it works.

It gave me the indentation.
