Never used Cake, but Lein works great.
Emacs is all about customization - something bothers you? Just change it
The standard keybindings are extremely bad, change them.
I use this one: http://xahlee.org/emacs/ergonomic_emacs_keybinding.html
Just ignore the controversy around the guy, the binding

Hi Clojure Gurus :)
I've a somewhat contrived use-case for macros that I've been
struggling with.
Let's say there's an interface called EWrapper that I'm trying to
implement with methods "tickPrice" and "tickSize", a concrete class

James,
For working with Clojure, if you are happy with Netbeans, use it. Especially
if you are relatively new
to Clojure, switching to Emacs won't do groundbreaking changes to your
productivity in the short term.
As you become more and more savvy with Lisp, Emacs will have more and more
to offer y
Hi,
I have 3 namespaces, each with functions that relate to the name of the ns:
core -- contains config and *server* var
query -- contains fn's related to querying
update -- contains update/delete fn's
I want to be able to "use" my core ns in my application, and call all of the
public fn's in

Hi,
these modern IDEs really do a tremendous job at organizing projects and
providing additional information at programming time. It's just, their
text-editor components suck.
If you are a Java developer, it's probably better to stay away from Emacs.
Should you ever get used to it, you're doo
Hi David,
Yes, the expansion I essentially want, and which runs properly without
the macro:
(proxy [EWrapper] []
(tickPrice [& args] (println "tickPrice" (. EWrapperMsgGenerator
tickPrice args)))
(tickSize [& args] (println "tickSize" (. EWrapperMsgGenerator
tickSize args)))
... other metho
So I realized that the method wasn't being found because args# is a
single argument, and I actually need it spliced in.
At this point I'm rather stuck. For example:
(defmacro make-msg-ewrapper [method-names]
`(proxy [EWrapper] []
~@(map
(fn [method-name]
(let [args (gensy

I'm currently using Eclipse with CCW and I quite like it. Much depends
on what you've been used to. I've worked in an Eclipse environment for
several years and use it for all my da
My main motivation for using Emacs is that it is rock-solid stable. I
look forward, however, to the day when the clojure plug-ins for the
other IDEs reach that level of maturity and stability, so I can leave
Emacs behind.
