a) You test your code using the REPL window. In the bottom there's a user input
area were you can run Clojure expression interactively.
The REPL panel has a couple of buttons in the top right corner.
You can see the last exception, interrupt processing if it loops forever,
...
The console is used to look at detailed error messages from the runtime
like exceptions.
b) When editing a Clojure source file, you can load it in a REPL directly
by using either a shortcut ctrl->alt->s or through the mouse-right-click ->
Clojure
menu. Look at the shortcuts available. You can reload a name space
in a running REPL on the fly, redefine stuff through cursor selection,
change the current name space in the REPL to the one of the source file
edited, ....
c) The time it takes to get the REPL alive can be significant depending on your
hardware. The idea is to avoid restarting it as much as possible by
reloading name spaces or redefining fns, ... w/o shutting down your
current REPL. Beware that in some cases it's unavoidable like when
you alter the project class path or if you are modifying java source code
part of your clojure project. The Java compilation will alter static files
not the loaded code in the JVM supporting the REPL.
Can't help you much with the menu that vanished but if you work
within a clojure source file and not the other way around, you should be able
to run it with the above indications.
Make sure that your project has it's Clojure nature enabled otherwise none of
the Clojure shortcuts will appear in the editor context menu.
