From d21224fdfe86fd9d3881537a2bc374a1fc7c1347 Mon Sep 17 00:00:00 2001 From: Don Viszneki Date: Thu, 10 May 2018 05:02:09 -0700 Subject: [PATCH 1/2] content script now doesn't rewrite code as refmt errors improved Refmt2: - eliminated Refmt2.refmtJS - Refmt2.refmt now uses bs-result protocol improved: - made refmt message serialization format more friendly: - using string for tag instead of integer - using jsConverter for payload record limitations: - Refmt2.refmt really needs a more complex result type to report degree of success or failure - code on page should contain the error
