[xrayw]

Hello, I use this useful lua ide to debug redis lua. I meet this error in debug mode.

Program starting as '"/Applications/ZeroBraneStudio.app/Contents/ZeroBraneStudio/bin/lua.app/Contents/MacOS/lua" "/Applications/ZeroBraneStudio.app/Contents/ZeroBraneStudio/packages/redis.lua" --instance redis://localhost:6379 --controller localhost:8172 --debug yes "/Users/user/Desktop/2.lua" txt , 1 2'.
Program 'lua' started in '/Applications/ZeroBraneStudio.app/Contents/ZeroBraneStudio/myprograms' (pid: 13869).
/Applications/ZeroBraneStudio.app/Contents/ZeroBraneStudio/bin/lua.app/Contents/MacOS/lua: ...neStudio.app/Contents/ZeroBraneStudio/packages/redis.lua:1831: attempt to index global 'socket' (a nil value)
stack traceback:

but if i execute it directly(not in debug mode), no error report

@xrayw, it looks like socket is expected to be a global variable, but the newer version of luasocket may not provide that. Can you try replacing socket in socket.tcp with require("socket"), so the line 1831 looks like this:

local server, err = require("socket").tcp()

@pkulchenko Hi, boss, require("socket").tcp() works for me. thank you very much.

my luasocket version: 3.1.0-1

i think we can check if the global socket is nil. we use require("socket").tcp()

I pushed a fix for it, but it can probably be updated to use (require"socket" or socket).tcp() to also work with some older "luasocket" versions. Does that still work for you?

[xrayw]

@pkulchenko (require"socket" or socket).tcp() also works for me.
