Get all function arguments

[Hardy]

Is there any method to get all function arguments(endless amount), because i writing my own chatbox and want to override chat.AddText to parse it.

[CombineGuru]

[lua]
function randomfunc(...)
print(unpack(arg))
end
[/lua]

-from ¦FJ¦

[MakeR]

[lua]function variadicfunc(...)
print(...)
end[/lua]

You can do that too, I think.

arg == {...}
unpack(arg) == ...

[CombineGuru]

It's a matter of preferance. I prefer using arg since, for one it's used in standard Lua. Second of all, you can use it as a table rather than a bunch of args.

If you're wondering, yes, I'm banned again ;) Requested it because Conna might have comprimised my account.

[MakeR]

I also prefer to use arg for the same reasons, Just giving other options.

Thanks

arg is deprecated.

21:09:02 Rcon: "lua_run function a(...) print(unpack(arg)) end"
21:09:03 > function a(...) print(unpack(arg)) end...
21:09:20 lua_run a("A" , "C" , "B" , 1 , 2, 3 , 4)
21:09:20 Rcon: "lua_run a("A" , "C" , "B" , 1 , 2, 3 , 4)"
21:09:20 > a("A" , "C" , "B" , 1 , 2, 3 , 4)...
         A<TAB>C<TAB>B<TAB>1<TAB>2<TAB>3<TAB>4

21:10:56 Rcon: "lua_run function b(...) print(...) end"
21:10:56 > function b(...) print(...) end...
21:11:06 lua_run b(1 , 2 , 3 , 4)
21:11:06 Rcon: "lua_run b(1 , 2 , 3 , 4)"
21:11:07 > b(1 , 2 , 3 , 4)...
         1<TAB>2<TAB>3<TAB>4

They're exactly the same. One is as good as the other.

[Overv]

Not really, with arg you can do a lot more than [b]...[/b]. With ... you can only forward arguments.

[andrewmcwatters]

So "arg" and "..." are actually referenced values in Lua? I learned something today. Thank you, Overv.

New question - how to find chat metatable(and override chat.AddText function)?

chat = FindMetaTable("chat") and
chat = FindMetaTable("Chat") not working.(returns nil)

[Overv]

chat is not a metatable, you'd just do this:

[lua]function chat.AddText( ... )
print( ... )
end[/lua]

or

[lua]chat.AddText = function( ... )
print( ... )
end[/lua]

What do you want to override chat.AddText for?

[andrewmcwatters]

chat is a library, not a metatable. Metatables are used with objects, such as Players, NPCs, or Entities. They can also be used with what I like to call theoretical objects, such as text, but this isn't an instance where that is so.

Ninja'd. :eng99:

[Hardy]

Thanks, i need override because there is no hooks to use with original chat.AddText for making custom chatbox

[editline]06:36AM[/editline]

One more question - string.len sometimes returning length = 2 for some symbols. How to detect those symbols?

[Crazy Quebec]

I'm pretty sure there is in fact a hook that detects text added with chat.AddText. I don't remember which exactly though.

[Overv]

This handles join and leave messages and I think the ChatPrint messages, but doesn't handle chat.AddText:
