Regex Editor & Tester

Parses nginx access logs in the combined log format, capturing named groups for client IP, remote user, timestamp with timezone, request method, path, protocol, status code, bytes sent, referer, user agent, and X-Forwarded-For header. Uses Go RE2 named capture groups (?P<name>...) making it suitable for Grafana Loki log parsing pipelines (logcli or LogQL pattern extraction). Handles missing values like '-' status codes and optional request components.
