I've explained my difficulties with permutation on this forum previously. It looks like x3 now has the binary parsers. Thanks for that! Since the majority of my qi parsers were binary parsers, x3 was a non-starter for me until that happened. The 'advance' parser component was also essential for binary parsing. I need to create an x3 repository version of it. ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
