How do you deal with multiple REPLs in cider?

How do you select the one you want to evaluate code against?

If I understand correctly, CIDER figures it out, nice

try M-x cider-connection-browser to see which nrepl is the default one

You can switch connections there if cider isn’t picking the right one

It got a little smarter a few releases ago so you normally shouldn’t need to do that

if you have multiple projects

if you are trying to, for example, talk to nrepls for two different instances of one project, then you’ll need to do the manual nrepl switching.

I sometimes do that when talking to the staging machines and want to check something on all N of our servers…. Launch a bunch of ssh sessions with ports forwarded to the nrepl port. M-x cider connect to them all and toggle through.

ok thanks @norman

How can you cancel the evaluation of C-x C-e when it takes too long?

C-c C-c should cancel it I think (but it may depend on exactly what the code is doing).

I think I lost my REPL by evaluating something huuuge

it’s back
