btw, I just tested with:
KSR.pv.sets("$var(x)", "{\"foo\":\"bar\"}");
KSR.pv.sets("$var(e)", KSR.pv.get("$(var(x){s.encode.base64t})"));
KSR.pv.sets("$var(d)", KSR.pv.get("$(var(e){s.decode.base64t})"));
KSR.info("===== data: " .. KSR.pv.get("$var(x)") .. " - " ..
KSR.pv.get("$var(e)") .. " - " .. KSR.pv.get("$var(d)") .. "\n");
and the log looks good:
INFO: <core> [core/kemi.c:107]: sr_kemi_core_info(): ===== data:
{"foo":"bar"} - eyJmb28iOiJiYXIifQ - {"foo":"bar"}
Cheers,
Daniel
