如何在REPL中找到函数定义？

Question

After experiencing several times, finally, I got a function works. After a few tests, I believe I could put this function to the source code file. But now the function definition is a long way burred in the REPL. I tryed

(source my-function)

Unfortunately, it doesn't work. It only work on the functions in the lib.

So I have to scroll back, and search (within Cider-nrepl,Emacs).

Is there a better way?

Assuming you're function definition starts with defn , within Cider/Emacs, you can type (defn at the REPL and hit Mp (Meta-p or Esc-p). This will find any previous input to the REPL that started with (defn . Hitting Mp multiple times will allow you to go backwards through history, ie it will find all input starting with (defn .

This of course works also for all other input to the REPL.
