Subject: lamp: lua5.0-isms in draw-{candle,staryeyes}
X-Git-Url: https://hydra-www.ietfng.org/gitweb/?a=commitdiff_plain;h=e68e815afc325193c03ea6517e45ebcf5e6990b0;p=acmetensortoys-esp-lua_lamp

lamp: lua5.0-isms in draw-{candle,staryeyes}

In particular, the use of the function-local "arg" is deprecated and
gone entirely in lua5.2. Switch to "ipairs{...}" rather than
"ipairs(arg)" which should work with both nodemcu and host programs.
