Toggle between the Clojure & ClojureScript REPL

[bbatsov]

If we have the two REPLs for some project it will be nice to be able to quickly toggle between them.

Any suggestion for a keybinding?

I immediately thought of C-c C-r(rotate repl), because I've never used that binding, but that's bound to eval region. Is eval region really something that's useful in the repl buffer?

[bbatsov]

I was thinking of C-c M-z. Frankly, I dislike the rotate terminology.

[Malabarba]

How about cider-other-repl under C-c o in analogy to other-window.

[bbatsov]

This is a keybinding reserved for users. (but I like the name for the command, this was my idea as well, although inspired by find-other-file).

[expez]

How about repurposing the C-c C-o binding? It's currently used by:

C-c C-o runs the command cider-repl-clear-output, which is an
interactive compiled Lisp function in `cider-repl.el'.

It is bound to C-c C-o, <menu-bar> <REPL> <Clear output>.

(cider-repl-clear-output)

Delete the output inserted since the last input.

Since we already have C-c M-o (which clears the entire repl) I've never found the need for C-c C-o.

[bbatsov]

It's pretty useful when the last evaluation dumped some huge output and you lost context because of it. SLIME has the same command with the same keybinding, so I'm guessing plenty of people are used to it.

[expez]

Right. What about repurposing C-c M-o then, and let C-c M-o be what C-c C-o does when given a prefix? That way C-c C-o clears the last or all output.

[Malabarba]

I like that.

[bbatsov]

I like it as well.

[arichiardi]

:+1 I use C-c M-o a lot, but I guess that change won' t bother me too much, it actually sounds more appropriate to have a prefix to C-c C-o

[bbatsov]

I didn't rebind the command in cider-mode, only in cider-repl-mode. Probably it'd better if it were changed there as well for consistency.
