It appears that tab completion does not work in the lua prompt on LuaJ archs, and further investigation finds that the reason is because the environment is failing to supply a list of available keywords -- and the reason appears to be that user defined __ipairs and __pairs metamethods are NOT called (__len and __index are). I have not tested other metamethods.

Paging LuaJ master @gamax92.

Sorry, something went wrong.

I think __ipairs is deprecated since Lua 5.3, because ipairs now respects __index. __pairs isn't though.

Sorry, something went wrong.

Without looking it up, I'll agree that sounds familiar :)
I felt it worth noting that the tab-completion bug needs __pairs fixed, not __ipairs.

Sorry, something went wrong.
