Re: How to print the content of Table/

[Emeka <emekamicro@...>]

Basti,

I am pretty new to Lua, so how do I run it without _G?

Regards,

Emeka

Hi,

Try this code:

table.foreach(t, print)

This table.foreach is a function to map algorithm (see
http://en.wikipedia.org/wiki/Map_(higher-order_function)).

Perhaps, you can write this:

function inspect(key, value)
 local prefix = name
 local out = prefix and prefix..".%s" or "%s"
 if type(value) == "table" then
   name = prefix.."."..key
   table.foreach(value, inspect)
   name = prefix
 else
   out = type(value) == "function" and out.."()" or out.." = %s"
   print(out:format(key, tostring(value)))
 end
end

name = "t"
table.foreach(t, inspect)

Don't run this code using the _G table. The C stack overflow is
throwed because _G has a reference to yourself.

Regards.
