Break not exiting while loop

[Catythcatmunchr 0]

For some reason break isn't exiting this while loop, when I input "exit" it just prints it and continues the loop instead leaving it.

While true do

  Local input = term.read ()

  Term.write (input)

  If input == "exit" then

    Break

  End

End

I believe term.read returns its input with a newline char (\n) appended to the end of its output. So, typing 'exit' would return 'exit\n'.

One option is to use io.read if you don't need all of the options term.read offers. io.read will return the input without a newline. Or, you can

strip the newline and compare as usual.

local input = term.read()

if input:sub(-2) == 'exit' then
	-- # I believe input:sub(-2) should strip the last two chars (\n) from the input variable...
end

Thank you, input:sub(-2) didn't work but io.read() did work. I searched through the documentation and you are correct that term.read() adds a newline char.

'\n' is one character so it may be sub(-1)

Thanks. It's always referenced as 'the' newline char
