As others have mentioned - you’re probably talking about something like a python or node repl. Lisp repl development is not like python or node - you _work_ in the repl. The closer comparison might be between bash+node as a repl - up+enter and the like to rerun tests has an equivalent in clojure+IntelliJ. There’s no copy pasting but there are different key bindings.

One of the best parts about lisp style repl development is that you end up doing TDD automatically. You just redefine a function until it does what you want from sample data you pass in - without changing files or remembering how your test framework works. You can save the output of some http call in a top level variable and iterate on the code to process it into something useful. The code you evaluate lives in the file that will eventually house it anyway so it’s pretty common to just eval the entire file instead of just one function.

Since you don’t ever shut the repl down, developing huge apps is also quite pleasant. You only reload the code that you’re changing - not the rest of the infra so things like “memoize” can work in local development. That’s why it’s a bit closer to your bash shell in other languages.

If you’ve never tried it, I highly recommend trying the Clojure reloaded workflow [1] to build a web app with a db connection. You can really get into a flow building stuff instead of waiting for your migrations to run on every test boot.
