So… I'm currently working on an OS called "WinOS". It's a pretty young project of about 270 lines of code. Currently I'm trying to make a "Add new User"-screen, in which the user writes in his username and password. I write all that data to a file called "%userdata" then, which looks like this after a fresh startup:


-
-
-
-
-
-
-
-
-

The maximum of users you can have is 3. That's why I programmed in an error which shuts down the PC when you try to add an fourth user. The only problem is, that I always get the error message, even if no users are registered! I really hope for a quick answer.

Here's the code (And yes, I know, it's not very organized):


---- Preparations ----
term.clear()
---- Draw Login Screen ----
--- Background ---
paintutils.drawFilledBox(1,1,51,19,colors.cyan)
--- User Boxes ---
paintutils.drawBox(6,2,15,11,colors.blue)

There are a number of problems with your code…

1 - if 'firstUDLine' equals "", userdata will closed when you get past that if statement.
Fix:


local userdata = fs.open("%userdata", "r")
local firstUDLine = userdata.readLine()
if firstUDLine == "" then
  userdata.close()
  local userdata = fs.open("%userdata", "w")

  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")

  userdata.close()
  userdata = fs.open("%userdata", "r") --#userdata has already been declared local to your script, don't make it local to this statement!
end

2 - each time you call userdata.readLine, it's going to go to the next line. Thus, this:

if userdata.readLine() == "red" then
  paintutils.drawFilledBox(7,3,14,10,colors.red)
elseif userdata.readLine() == "blue" then
  paintutils.drawFilledBox(7,3,14,10,colors.blue)
elseif userdata.readLine() == "green" then
  paintutils.drawFilledBox(7,3,14,10,colors.green)
else
  paintutils.drawFilledBox(7,3,14,10,colors.white)
end

..will likely move 3 lines if the line did not contain "red".

Fix:


local c = { red = colors.red, blue = colors.blue, green = colors.green }
paintutils.drawFilledBox( 7, 3, 14, 10, c[ userdata.readLine() ] or colors.white )

Thanks for your answer, but sadly this didn't solve any of my problems, it only got me some new ones.

1 - if 'firstUDLine' equals "", userdata will closed when you get past that if statement.
Fix:

local userdata = fs.open("%userdata", "r")
local firstUDLine = userdata.readLine()
if firstUDLine == "" then
userdata.close()
local userdata = fs.open("%userdata", "w")

userdata.writeLine("-")
userdata.writeLine("-")
userdata.writeLine("-")
userdata.writeLine("-")
userdata.writeLine("-")
userdata.writeLine("-")
userdata.writeLine("-")
userdata.writeLine("-")
userdata.writeLine("-")

userdata.close()
userdata = fs.open("%userdata", "r") –#userdata has already been declared local to your script, don't make it local to this statement!
end

This wasn't exactly right. This works for me although:


if fs.exists("%userdata") == false then
  local createUserdata = fs.open("%userdata", "w")
  createUserdata.close()
end

local userdata = fs.open("%userdata", "r")
local firstUDLine = userdata.readLine()
if firstUDLine == nil then
  userdata.close()
  local userdata = fs.open("%userdata", "w")

  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")
  userdata.writeLine("-")

  userdata.close()
  userdata = fs.open("%userdata", "r")
end

2 - each time you call userdata.readLine, it's going to go to the next line. Thus, this:
if userdata.readLine() == "red" then
paintutils.drawFilledBox(7,3,14,10,colors.red)
elseif userdata.readLine() == "blue" then
paintutils.drawFilledBox(7,3,14,10,colors.blue)
elseif userdata.readLine() == "green" then
paintutils.drawFilledBox(7,3,14,10,colors.green)
else
paintutils.drawFilledBox(7,3,14,10,colors.white)
end
..will likely move 3 lines if the line did not contain "red".

Fix:
local c = { red = colors.red, blue = colors.blue, green = colors.green }
paintutils.drawFilledBox( 7, 3, 14, 10, c[ userdata.readLine() ] or colors.white )

I replaced my old code for every User with your fixed code and edited the paintutils coordinates. Result: User 1's color displays in User 2's picture and the other ones don't display at all.

Help :(/>

There are probably more errors in the code than I found, I'd not read through the whole thing. If you could post the updated code so I know how you tried to use my fixes, I might be able to figure out the problem.

So I did a bunch of stuff to the top half of your code, it works now… I think.

Well, it kinda works, it just overwrites the .userdata on every startup with this:


--UserData--
--

I dont understand why there is so much going wrong with my code. :(/> xD

It shouldn't… I tested my code myself. For me, it doesn't overwrite the .userdata file if –UserData– is left at the top.

So that's what I did wrong, I deleted the –UserData– on top… >_<
