Why can’t we get Lua debug info on device? Is this possible? Is it a bug?
This works fine on simulator but not when tested on Device (Android, Galaxy S4).
I would like to use Lua debug info to build an advanced logging module for Corona.
[lua]
local debugInfo = debug.getinfo(i)
table.foreach (debugInfo, print)
[/lua]
Thanks,
Daniel
perhaps it’s a violation of store terms to include “introspective” stuff
perhaps like loadstring()'s absence - no dynamic code
?
That could be it. Maybe there is another way to get debug info on device? I hope to get a response from Corona team.
Anyway, here is my logging module: https://github.com/promptcode/CoronaAdvancedLogging

I’ve asked Engineering about it.

You’ll need to build your app with debug symbols for those functions to work (the Simulator always compiles Lua with debug enabled). Take a look at the Build Control section in the Project Build Settings documentation.
That’s it, thank you 
I will update the library and sample ASAP: http://forums.coronalabs.com/topic/50004-corona-advanced-logging/
