👋 Does anyone know of a stand-alone nREPL client with similar featureset to REPL-y but with fewer/smaller dependencies? Ideally no JVM Readline and tab complete would be the main things I’m after

there is https://github.com/eraserhd/rep. i've never tried it, so i can't speak to what features it has, but maybe it fits the bill

the scenario is i’ve got some tools we’re bundling into a container that will include connecting to an nrepl server, and i’d like to avoid having to include a whole jvm in there if possible

@glenjamin it's possible to interact with an nREPL server from a bb script as well: https://book.babashka.org/#_interacting_with_an_nrepl_server

but this is possibly lower level than you would like

I'm using this on our CI to send commands to our production app, e.g. to clear caches

i suspect for now we’ll just bundle the usual lein repl stack, we did briefly try a graal compile and quickly abandoned it

@glenjamin if you would like to do without lein:

clojure -Sdeps '{:deps {reply/reply {:mvn/version "0.4.4"}}}' -M -m reply.main --attach localhost:1667

cheers, we might try that, but i think once we’ve got the JVM in there then lein isn’t much on top

@glenjamin There's a list of clients here: https://nrepl.org/nrepl/0.8/usage/clients.html#command-line-clients Not sure if any of them fit the bill.

@glenjamin I have some success with reply on GraalVM, working around some issues in complete.core, reflection etc, etc.

$ ./reply --attach localhost:52612

ExecutionException java.io.FileNotFoundException: Could not locate reply/parsing__init.class, reply/parsing.clj or reply/parsing.cljc on classpath.

One of the issues is that reply "complects" the in-process REPL with the client

please don’t sink time into it on my account! This was only a “it’d be nice if my container was a few hundred MB smaller” idle thought

:thumbsup:

At least this works if I close the REPL:

$ ./reply --attach localhost:52612
ConnectException Connection refused (Connection refused)

ehm... it works!

^ @glenjamin...

oh wow, nice one!

@glenjamin I just realized, I've been using CircleCI so much for my open source projects, I owe at least to publish this code, if you're interested.
