I am using a similar approach to filter network flows, but the language is just SQL-like (notably because users may not be familiar with all the quirks of SQL) and gets translated to ClickHouse SQL. The language is exposed to the end user, so there is completion and syntax highlighting. Since the result is open source, you get a complete example (notably to evaluate how complex this is).
