Choosing an Editor or IDE

What matters most: REPL integration, evaluation controls, and good stack traces.

In Clojure, your editor is not just a text editor. It is the main control panel for your REPL-driven workflow: evaluating forms, reloading code, inspecting values, and navigating stack traces.

What matters more than brand

  • A reliable way to start/connect to a REPL.
  • Evaluate a selection, a top-level form, or a whole file.
  • Jump to definition for vars and namespaces.
  • Inline results or a good REPL window for inspecting values.
  • Stack traces that show you the relevant Clojure frames (not just raw Java noise).

Java mental model: think “IDE + debugger”, but replace step-debugging with “evaluate small forms and inspect values”.

Pick the editor you will actually use daily. The best setup is the one that keeps your inner loop fast and frustration-free.
