Highlight of open/close characters

Analysis

Summary

In a context where we have a nesting of complex objects as operation parameters, it is difficult to match the '{' and '[' with their closing counterparts. In particular at the end of the command, it is needed to quickly identify missing closing characters.

We are proposing here to highlight the matching pairs when the cursor is on the closing character.

Requirements

When moving the cursor onto a closing character (‘]‘, ‘}’, ‘)’), the opening character ( ‘[‘, ‘{‘, ‘(‘ ) should be highlighted. If no match is found, then the current closing character should be also highlighted (e.g.: in red to make it clear that it is an error). The user typed content must not be affected by the highlighting (e.g.: when executing an operation that would contain colored character).
