Boot Script Password Protection

[Memelord420 1]

So, basically I want to password protect my computer, and autorun.lua doesn't work when the computer starts, so I decided to make a boot script. The script runs last during the booting process, but this extremely simple code I'm trying to run bluescreens me and forces me to reinstall. (It's not that big a deal because I'm testing it all in creative before I bring it to survival) If anybody could help me, I'd appreciate it.

Broken Code:

local computer = require("computer")
local io = require("io")

print("Access Restricted")
print("Password: ")
password = io.read()
if password == "Password" then
	print("ACCESS GRANTED!")
else
	print("ACCESS DENIED!")
	computer.shutdown(true)
end

What's the bluescreen error and how are you running the script?

The bluescreen error is

init:93: /lib/term.lua:234: attempt to index local 'w' (a nil value)

and I'm running the script just by making it in the boot directory. I didn't change anything in init.lua, I just figured that the highest number boot script gets ran last, so I made a boot script called 100_password.lua and it got ran, but it bluescreened me.

There seems to be a bug in the term lib loading a tty window. I think perhaps tty isnt fully loaded yet..? Try using term.read instead of io.. Maybe that'll help... If you get a new error that'd be helpful.

It didn't give me a blue screen, but now it's stuck in a reboot loop.

yes - this is a bug in openos when users try to print to the screen before boot is finished

I have this fixed, you are running an older version of openos

Note that if you pull the latest code, it will fix your problem and you won't get a blue screen. However, you also won't get the text printed to the screen because the terminal isn't finished loading yet.

If you want to print to the screen in a script that runs automatically during boot, you need to add your programs to /home/.shrc

Things that run in /boot, or autoruns, or rc scripts, may be executing before the terminal has initialized

If you want to run your code before /home/.shrc is run (happens when the shell loads) then you'll have to wait for the terminal to become available, that is, you'll need to:

      if not term.isAvailable() do
        event.pull("term_available")
      end
