Background

Currently, the TraceQL input is a plain text box. To enhance this, we could add lezer-traceql [1]. 

"Lezer (the Dutch word for reader, pronounced like “laser”) provides a parser generator that outputs JavaScript modules, which can be loaded to parse code into a non-abstract syntax tree. This tree can then be used to do highlighting and basic semantic analysis." [2]
