Test, validate and match regular expressions
Matches X-Plane-style 'get value' command strings, starting with 'get' optionally followed by a partially or fully spelled 'value' (e.g., get, getv, getvalue). It captures a slash-separated dataref path made of alphanumeric/underscore segments (like sim/cockpit/autopilot/heading), then an optional numeric argument and an optional true/false boolean flag. Useful for parsing simulator command lines or config scripts that read X-Plane datarefs.
