ok i am making a nice file viewer for an OS i plan to make but when i run it

local files = fs.list("/")
print(files)

it says table: and then a random amount of numbers / letters
how do i make it print the the contents of directory / and not the numbers/letters

You can't really just print a table, haha.

You have to go through the entire thing and print each of its values individually.

for _, file in pairs(files) do
  print(file)
end

can you please explain how that code works?

I was going to ask the exact same question.

EDIT: Did some quick googling:

Spoiler

They loop through a table

tbl = { apples = 2, oranges = 3 }
for k, v in pairs(tbl) do
print(k, v) -- K = apples, oranges V = 2, 3
end

Ok thanks for the help

You could run a for loop, its easier to understand:

for i = 1, #files do -- #files returns the length of the table "files"
  print(files[i])
end

Thats how I first learned to do it, but the above solution is probably better />

You can use either one, really. It's a matter of preference.

The iterative for loop is faster than the in pairs, but in pairs doesn't require you to save the table into a separate variable. I've found it's a little harder to screw up with in pairs, which can be a factor.
