When I manually edit json files, I end up with red boxes falsely alerting me to syntax problems until I take manual action to refresh those lines.
I start with a file with a key/value pair:
{
"key1":"value1"
}
If I want to add another key/value pair, my first keystrokes are Enda,.
At this point, the comma is highlighted RED. This makes sense because it is a syntax error. to have a comma with nothing afterwards.
Next I add the new key/value:
Enter "key2":"value2"
The red over the comma persists until I refresh that line by temporarily adding a character after it, or reloading vim. That significantly increases the number of keystrokes I need when editing files. It also means I tend to ignore legitimate mistakes that I would prefer to address right away.
How can I get the syntax highlighting to auto-update for the previous line?
Here's vim --version if relevant.

git clone https://github.com/vim/vim.gitright now. – Stewart Oct 13 '23 at 13:11vim8.2. andvim9.0 and see the same behaviour in both. I see Vivan's work-around now. If I move the cursor to one of the closing bracket of the object, the highlight refreshes. That will work for me. Thanks. – Stewart Oct 13 '23 at 13:19
