Help

Hi,
I'm clearly new to lua and I can't figure out how to make my program work like the "excavate" what I want is to make my program call with the variable that corresponde to how many times I want it to loop. Just like excavate 3 for example.

Can someone help me?

p.s.: Forgive my english faults, not my native language

Look into tArgs

tArgs = {...}

if tArgs[1] == 1 then
  print("uno")
else
  print("spanish for not one")
end

then if you run <filename> 1 it will print "uno"

Basically {…} makes a table based off parameters called. and you can access those parameters with <var>[number]. I'll show you below, but this is something you would use if you wanted to make a function with an unset amount of parameters.

-- I showed you in my last comment how to use it when running a program.
-- this will show you how to use it in a function
local function helper(...)
  local t = {...} -- makes a table with the parameters put in when the function is called.
  for i = 1, #t do -- loop through all of t.  using # tells it to basically loop through the whole table.
    print(t[i]) -- all the parameters
  end
end

helper("hello", "world", "what", "a", "great", "day")
-- outputs
hello
world
what
a
great
day

Thank you so much, that was exactly what i was looking for

How do I count the number of args that was inputed?

You can use '#'

local numberOfArguments = #tArgs

the value in numberOfArguments will then be equal to the number of arguments passed

fun fact: 'tArgs' is commonly used as shorthand for 'table of arguments'

The arguments can't be words? Or i'm just not making it right?

The arguments are strings. They are stored in a table.

 print( ... ) --#passes ALL arguments to the print function
 tArgs = { ... } --#make a table of the arguments so we can use them individually
 print(tArgs[1]) --#passes the first argument to the print function
 print(#tArgs) --#passes number of arguments to the print function
 tArgs[1] = tonumber(tArgs[1]) --#convert the argument to a number if possible

You get a table from {…} and in that table there can be any type of variable that you pass to the program.

testProgram 1 abcd true

Inside the program:

args = {...}
for i, j in pairs(args) do
   print(type(j))
end

Output:

number
string
boolean

–EDID Fixed in pairs code

You forgot to pass in pairs a table

Lol, noob-derp. Fixed.

I figured you just quickly typed it up. I've done that several times.

well actually the output would be

string
string
string

you have to convert the arguments to the data type that you want. adding this code before your pairs loop would result in the output you stated

args[1] = tonumber(args[1])
args[3] = args[3] == "true"
