"You can exit the Tokay REPL with Ctrl+C."

Other repls often use ctrl-d for end of Input Stream instead. Ctrl-c is rather expected to Interrupt the programme execution, not the repl.

The Lua REPL also terminates on Ctrl-C, which can be infuriating when you’re accustomed to Readline’s interpretation of “abort history editing and clear input”.

Ctrl+C for Elixir's iex as well. When i first used it I had to Google, it was that special "how to exit vim" moment for me.

Perl's re.pl exits on ^C too (as well as ^D). Ditto Clojure.

The even more annoying thing is that it's Ctrl+C twice.

Clozure common lisp is Ctrl+D three times.

Well, at least there's a reason for this: Elixir REPL is actually a remote shell, and the first Ctrl+C is an escape sequence that drops you into local connection manager. You of course know this, but I thought I'll leave it here for people who don't :)

TIL, in fact. I had a vague understanding of it - I knew that the REPL was sort of "sshing" into the actual BEAM process, but your explanation cleared it up. Thanks!

I often use Ctrl-C to abandon a command I'm typing and get a new prompt.
