用“ n”退出滑轨控制台

Question

I noticed a weird thing. I accidentally typed:

@a = n

which led to exit of rails console.

On further experimenting I found out even if I just do (in console)

n

The console exits. If I try any other character, I get error as expected.

a
# => NameError: undefined local variable or method `a' for main:Object

I was not able to find any documentaion that stated n is used to exit rails console . Is this normal? Or my console is breaking cause of some thing that I dont understand at all?

Versions:

ruby 1.8.7 (2012-06-29 patchlevel 370) [x86_64-linux]
Rails 3.2.13

This is a known issue in debugger. Go through here https://github.com/cldwalker/debugger/issues/133 . This is also with pry https://github.com/nixme/pry-debugger/issues/55 .

Answer 2

Well, works as expected (undefined local ...) for me at least. Ruby 1.9.3

Consider reinstalling ruby, maybe? :)
