#242256 How to break a loop out of scope

Posted by LoganDark on 03 January 2016 - 04:50 AM in Ask a Pro

You could call error without any arguments as such, which will instantly stop the program:

error()

I'm wondering if that will stop the program without causing a newline, hmm might have to test it. Going to edit post after testing.

Edit: I have tested it and it works perfectly! Thanks!

{see above}

However, in my opinion, this is a very ugly solution. I suggest you do something like this instead:

local keepRunning = true

while keepRunning do
   --# ...
end

Now if you set keepRunning to false, the loop will stop. Keep in mind that if you do this while the loop is running, the loop will finish its current iteration before it stops.

I have tried that, and it seems to work most of the time, but I don't think this is the correct solution.

#242228 How to break a loop out of scope

Posted by LoganDark on 02 January 2016 - 11:39 PM in Ask a Pro

I've discovered there is no way to stop a "while" loop from a function defined out of scope, for example this will not work:

function stop()
  term.setTextColor(colors.white)
  term.clear()
  term.setCursorPos(1, 1)
  break
end

while true do
  print("Exiting program in 2 seconds")
  sleep(2)
  stop()
end

Because, from the scope of the function, there is no loop to break, unless it is defined inside of the loop, as such:

while true do
  local function stop()
    term.setTextColor(colors.white)
    term.clear()
    term.setCursorPos(1, 1)
    break
  end

  print("Exiting program in 2 seconds")
  sleep(2)
  stop()
end

Unfortunately, this function can only be used inside of the loop it is defined within, and loops nested inside that use the function will end the loop the function is defined in.

I would like to be provided with a function that can be defined once and end all loops, to ultimately stop the program, but while clearing the screen and stopping all loops.

#241977 Compress - Transform a folder structure into a single self-extracting file!

Posted by LoganDark on 31 December 2015 - 06:54 PM in APIs and Utilities

Encryption seems like a great idea! Allow people to specify a password for the file, and when you run it, have it ask you for the password, and if it is correct (store a sha256 hash of the password inside) then decrypt the stored program (using the password), hide it somewhere (maybe make it .temp) and run it!

#240430 Beep Tone

Posted by LoganDark on 13 December 2015 - 10:33 PM in Suggestions

You should be able to control the tone of the beep.

I think this would be a good idea, but it should have a cooldown to prevent beep spam.

Also, only advanced / command computers should have this feature.

#239959 [CC1.75] Crash on creating a new world

Posted by LoganDark on 09 December 2015 - 04:16 PM in Bugs

Updating Java didn't fix the problem, unfortunately.

Edit: Oops, the render distance likely was higher than 32. I lowered it to 3 and MC worked perfectly! Thanks!

I have solved the problem! My render distance was set higher than 32.

I'm also running this on a MacBook from early 2008, not sure if that has something to do with it but yeah.

Also, here's the data I get on launcher start:

I haven't tested it, but I did see one thing in your code that I'd recommend doing differently.

On line 189 you set os.pullEvent = os.pullEventRaw but you don't backup os.pullEvent or restore it when the script is done. This will disable CTRL-T for everything on that computer until a restart (which will run your login and disable CTRL-T again).

I'd recommend doing the following. On line 189 backup os.pullEvent before pointing it os.pullEventRaw...

local oldPullEvent = os.pullEvent
os.pullEvent = os.pullEventRaw

Then at the end of your code, restore os.pullEvent so the computer operates as expected...

os.pullEvent = oldPullEvent

Oh, sorry. I seem to have forgotten the fact that the os.pullEvent is global. Silly me, fixed. Restarting the computer will apply the patch.

Also, not to be rude or anything, but you do not have to provide a method to restore it. I can figure things out on my own.

P.S. You did not offend me, what I have written may suggest you have.
