VERSION:
MC 1.7.10
Forge 10.13.2.1230
CC 1.74

DESCRIPTION:

CraftOS 1.7 shuts down whenever I type the word "type", followed by a space.

EXPECTED RESULTS:

Autocomplete guessing the first file/dir (".", meaning self) in the current directory

REPRODUCTION STEPS:
  1. Open the gui of any of these fine devices.
  2. Type in "type " (with the space but no need for enter)
  3. Watch the shell crash and the OS shut down.

SCREENSHOT:

POSSIBLE CAUSE:

Error on line 247 in bios.lua?

EDIT:

Manual debugging ftw. The row 247 of bios.lua contains the following:

tCompletions = _fnComplete( sLine )
The only call I see there is _fnComplete, which for some reason is nil for the "type" command only. The weirdest is the fact that the line just above it checks if _fnComplete exists, like this:

if _fnComplete and nPos == string.len(sLine) then
Also note that this is from the built-in "read" function, and _fnComplete is supposed to be the autocomplete function. I also dug in /rom/startup and … oh no…….. there's a…. TYPO!!! QUICK! TELL DAN THAT /ROM/STARTUP:184 IS SUPPOSED TO BE 

shell.setCompletionFunction( "rom/programs/type", completeEither )
(or just let everyone use a quicker badass shutdown by reproducing the bug)

Can confirm, this affects computers in CCEmuRedux as well.

Lemme just post a jar with the fix… (or you can debug it manually). Here. Hehe, this is like a modded mod :D/>/>

I have NO IDEA how to fix CCEmuRedux though. Maybe you can find the CC jar in ccemu's folder?

Please do not redistribute modified ComputerCraft files. You've posted a fix, and we should see that it gets added to the next version.

Oh sorry. I didn't know.

It can happen because even programmers make typos.

Also note that the type command can still be used, you just have to be careful. Step by step:
  1. Type "tye", "typ", "ype" or anything of the kind.
  2. Type the path of your file.
  3. Fix your spelling in the beginning.
  4. Press enter.
