Question re Mikael Sundberg's Getting started with compojure

[Jacek Laskowski]

Hi,

I've been reading Mikael Sundberg's Getting started with compojure [1]
and been wondering how to reload a function "display" (without Emacs
and swank) so I don't have to restart repl. I'd love to update the
function while running lein repl. Is it possible?* How?

* I know it's possible, but dunno how and therefore the question :)

I'm not sure if this is the question you are asking, but to reload a namespace in a repl, depending on whether you are use-ing the ns or require-ing it, there are :reload and :reload-all  keyword arguments accepted:

(require '[foo.something :as something] :reload)

(require '[foo.something :as something] :reload-all)

Thanks! That was it.

As we're at it, how does people reload functions while connected to a
remote Clojure app from within Emacs? Do they also
(require...:reload)? Is there a tutorial/article about it?

One possibility is to open the remote file wherein the function in
question is defined, modify it as appropriate, then either enter
(require :reload ...) at the REPL or press C-c C-k (a SLIME / Swank
binding) in the buffer with the modified code. (Or press C-c C-c with
point inside the top-level form in question.)

Another possibility -- which is open even if the app has been packaged
as a .jar / .war file -- is to switch to the appropriate namespace at
the REPL and evaluate the appropriate defn; or maybe stay in the user
namespace and use clojure.core/intern / alter-var-root / .bindRoot to
replace the root binding of the Var holding the function.

Sincerely,
Michał
