How to create error messages in ace code

Question

I am using the Ace editor to display code on a website. I would like to be able to highlight code ranges and display an error message when they freeze as shown.

I'm not sure if this can be done using the Ace editor API, or if I need to use jQuery magic.

Answer 1

There is no api for this.

You can add a tooltip similar to token_tooltip to the ace , but it needs some processing to add an arrow and not move with the mouse.
