Basically, I'm typing along just fine in terminal, using IRB to run ruby commands:
2.0.0-p0 :014 > bank_account.withdraw(2222) => -1222
But sometimes I accidentally miss out a quotation mark.
2.0.0-p0 :020 > BankAccount.create_for("Jim","Johnson) 2.0.0-p0 :021"> bank_account.withdraw(333)
If you look carefully, you'll see that the speech mark I missed out appears next to the line number on the left, next to the patch version.
From here on in, that speech mark appears everytime I run a command! And it stops the commands working:
2.0.0-p0 :021"> BankAccount.create_for("Julian","Hurley") 2.0.0-p0 :022"> BankAccount.create_for("Katt","Smith") 2.0.0-p0 :023"> exec($0)
What I want to know is, how do I get rid of that quotation mark? Or quit IRB from the command line in order to reset it?
In the Terminal app on your Mac, choose Terminal > Quit Terminal.
On Mac OS X or Linux you can use Ctrl + L to clear the IRB screen.
To access IRB, just type irb in the terminal. IRB allows you to do anything you can do in a Ruby file. For instance, you can do math, get the time by typing Time. now , or print text to the screen.
If you haven't closed a quote, just put a quote in and hit return.
Exiting from the console can be done by typing exit, though in the circumstance your are would need to hit Control - C
Control - C followed by Control - Z. I hope it helps!
