Test, validate and match regular expressions
Parses MBUS bus-monitor log lines into named capture groups, extracting a timestamp (YYYYMMDDTHHMMSS), RTI label, numeric timestamp, bus ID, hex command (C), status word (S), RT value, RDI and EOT hex codes, and space-separated hex Data/REPLY byte sequences. Useful for decoding embedded or industrial bus traffic logs into structured fields for analysis. The gm flags allow it to match every line across a full log file.
