How to terminate the process in cider-repl?

Question

When running into a deadlock because of an infinite loop, how can I exit from the cider-repl?

When it happens, I have to kill the emacs, or even reboot my computer to kill the cider-repl. Is there a better way of solving this?

Answer 1

The key combination C-c C-c will break from a loop at the top level of the cider repl, while leaving emacs and the repl running.

In a regular terminal repl, the equivalent is C-c.

Answer 2

When you're editing a file and have 'jacked-into' a cider repl, by default typing C-c C-c runs cider-eval-defun-at-point, but typing C-c C-b runs cider-interrupt, which cancels whatever is being evaluated.
