You can add :repl-options {:init-ns user} in your project.clj to load a different namespace (it’s ok if that ns doesn’t exist)

Hmm, I get an error when I start the REPL with that option: Never mind, the error was coming from something wrong in my Run Configuration.

I have a project that uses java logging and it doesn't output in the repl window either. What I generally do is start the app from the command-line in the IntelliJ terminal window (or an external terminal) and then connect to it with a remote nrepl connection. Console logging then appears in the terminal window.

I created my project from the command line with "lein new app <project-name>" then I "Open"ed the project.clj in Cursive and "open as project". Then I "Run 'REPL for <project>'" from the application Run menu. Here's my run config and project.clj.

I have been working in my <project>/core.clj file. I think lein is compiling my :main namespace, and in the process evals the code I'm working on (which is what I want to avoid). It looks like I can prevent this by setting the project.clj option :main nil.

@ben.grabow Yes, that makes sense. In Clojure, compiling a namespace effectively evals it, so if it has side effects they will happen during compilation.

Makes sense. And I see now that if I run lein repl from a shell at my project directory I get the same behavior, so obviously not a Cursive-specific thing. Thanks so much for your responses, and all your work on Cursive of course!

No problem, I’m glad it’s working!

Or at least, it’s clear why it’s not working 🙂

Is there a way to "load current namespace in repl" automatically when the repl starts? The hooks in the Run Configuration looked like they all apply prior to the repl starting.

"Switch REPL NS to current file" is what I mean, in the Tools > REPL menu

The problem is that it isn’t always clear what the current namespace or file is when you run a REPL. You can do this with a user.clj file at the Clojure level, rather than in Cursive. Since the default namespace in the REPL is user, if you have a user.clj file at the root of the classpath it will be eval’ed when you start your REPL, and you can do what you like in there.

Root of the classpath is typically <project-dir>/src/ right? Probably depends on my :source-paths option in project.clj?

@ben.grabow That’s right.
