Question

Let’s say I’m working on an html file, and my cursor is between the open and close tags:

<button>I</button >

when I hit enter, I want vim to automatically format to this:

<button >
  I
</button >

I is the cursor position.

I’m thinking about modifying vimrc file, something like:

inoremap <CR>  "if previous character is > and next character is <, then <CR>O"

But I don’t know how to get the previous/next character of the cursor.

I hope this makes sense,
I tried to search everywhere but I couldn’t find any help, maybe I’m searching for the wrong keywords, or taking the wrong approach.

Answer 1

inoremap <expr> <CR> '<CR>' . (search('\V>\%#<','bcn') ? '<Esc>O' : '')
