[Someone Else 37]

The number of currently-discovered elements on the Periodic Table

121 Why would you ever say such a thing @CoolSquid?

 

[erindalc]

1+2=3 Welp

 

[lenscas]

local t={}
setmetatable(t,{
__index = function(t,k) return {1,2,4} end
})

print(table.concat(t.luaBeingLua,""))

Guess what this does and how it works. (assuming I didn't screw the code up which is possible as I did not test it)

edit: I should have just done this

local t={}
setmetatable(t,{
__index = function(t,k) 
   return 1,2,4
end
})

io.write(t.luaBeingLua)
io.write("\n")

I worked too much with languages that can only return 1 thing >_<

 

[erindalc]

125 You forgot something

125 You forgot something

? What did I forget?
if you mean that I forgot to give t.luaBeingLua a value then that is not the thing I forgot as it should work correctly

 

[erindalc]

127 You forgot a number

 

[lenscas]

128 ?_?
124 was the number for that post right?

 

[erindalc]

129 Yes

 

[lenscas]

130 then what number did I forget?

I just can't today

132 also, about what it is supposed to do:
When you want to find a value in a table that is not set lua looks for the __index value of the metatable of that table. If its a function it executes it

Thus when I asked it to find the value of luaBeingLua in table "t" it should run the index value and thus return 1,2,4.
io.write() takes an infinite amount of arguments and print them. However unlike print() it doesn't put a newline character at the end of it and what it needs to do when the arguments are split are very strictly documented, unlike print which depending on the interpreter will either print a tab in between the values, a space or perhaps even nothing (which I don't think I encountered yet myself but I wouldn't be surprised if there is an interpreter out there that does that).

However I personally never found this a problem due to me either only using print to debug things (not in all projects but like the thing I am working on right now that is defiantly the case), I know how the interpreter that it is going to run on handles it or because the difference is just very tiny

2 @lenscas But isn't that needlessly complicated for printing a three digit number?

 

[lenscas]

3 yes, yes it is and it was exactly supposed to be that
