Combining Tables

--# Just an example table
local t = {
    "hello", "world", "foo", "bar"
}
local text = "" --# This would be the string you'd send
for i = 1, #t do --# Loop through all the other strings
    text = text .. t[i] --# Concatenate the strings
end

print( text ) --# Outputs: helloworldfoobar

From what I understood you want to do something like this?

--# Just an example table
local t = {
	"hello", "world", "foo", "bar"
}
local text = "" --# This would be the string you'd send
for i = 1, #t do --# Loop through all the other strings
	text = text .. t[i] --# Concatenate the strings
end

print( text ) --# Outputs: helloworldfoobar

Do you have any code? If so, then please post it, as it would be helpful for a better understanding of what you mean.

I'd say you're running the program with less than 3 arguments. What exactly are you giving it for arguments?

My guess would be that it's this part that errors

for i = 3, #tArgs do --starting from 3 because the msg starts from the 3rd value.
	text = text.." "..tArgs[i]
end

wouldn't that part be this instead

for i = 2, #tArgs do
	text = text .. " " .. tArgs[i]
end

because the usage is "say <message>" and not "say <parameter> <message>"

edit: ninja'd :ph34r:/>

 for i = 2, #tArgs do 

elseif sCommand == "tell" then

text = text.." "..tArgs[i]

if sCommand == "say" then

  local text = ""
  for i = 3, #tArgs do
    text = text.." "..tArgs[i]
  end
  print( text )

elseif sCommand == "tell" then

for i = 2, #tArgs do

local tArgs = {...}
if #args < 1 then
    error( "Usage: chatbox <text>" ) --# In this case "chatbox" would be the name of your program
else
    print( args[1] ) --# But when printing the first argument in the varargs table it prints whatever "<text>" was, and not "chatbox"
end

local t = {"hello", "world", "foo", "bar"}

rednet.send(id, t)

local t = rednet.receive()
for i = 1, #t do print(t[i]) end

print( table.concat( tArgs, " ", 2 ) )

I want to add a function that, if tArgs[2] (the second argument) equals "-l" then the rest of that is the label

tArgs = {...}

local labelPos = #tArgs+1 --# A variable to store the position of "-l" - It defaults to the length of tArgs
for i = 3, #tArgs do --# Start from 3, 1 is "say" and 2 is the message - lets assume the message has to be at least 1 word
  if tArgs[i] == "-l" then
	labelPos = i
	break
  end
end

local msg = {} --# Stores the message
local label = {} --# Stores the label, if there was one

for i = 2, labelPos-1 do --# Continue until one before "-l", or the end of tArgs if we didn't find "-l"
  msg[ i-1 ] = tArgs[i] --# Copy the message from tArgs to msg
end

msg = table.concat(tArgs , " " , 2 , labelPos-1)

label = table.concat(tArgs , " ", labelPos+1 , #tArgs)
--# Note the second one shouldn't do anything if "-l" wasn't found

local msg = {} --# Stores the message

for i = 2, labelPos-1 do --# Continue until one before "-l", or the end of tArgs if we didn't find "-l"
  msg[ i-1 ] = tArgs[i] --# Copy the message from tArgs to msg
end

msg = table.concat( msg , " " )

local msg = table.concat( tArgs, " ", 2, labelPos - 1 )

you could instead just do:

local msg = table.concat( tArgs, " ", 2, labelPos - 1 )

Can someone provide me with the two functions (say and tell) with the label functionality as well please

chatbox say <label> <message>
chatbox tell <player> <label> <message>

chatbox tell bob "Chat Box" "hi bob"

print( textutils.serialize( tArgs ) ) -->
{
  "tell",
  "bob",
  "Chat Box",
  "hi bob",
}
