groovysh: how to deal with a typo

Question

This seems like a really silly question, but when I use groovysh, if I have a typo, it seems to kill the entire shell.

For example, if I want to iterate through an array, I can do this arr.each { elt ->. But if I accidentally type arr.each { elt =>, then every future line I type results in

groovysh_parse: 2: unexpected token: > @ line 2, column 13.
   arr.each { elt =>
               ^

I can't get back to a working shell without killing the shell and restarting it, which means I lose all the work I've done in the shell.

Is there a way to get out of this?

Probably better to use groovyConsole if you need to type a lot of code. — Evgeny Smirnov, Jan 23 '18 at 19:34

There are a couple ways to get out of this. One is to clear the entire buffer using :c. The other is to edit the current buffer and fix your typo using :e.

In older versions of Groovy, the command prefix was '\' i.e. \c and \e.
