Hi,
the macro only works with the vector itself,
because otherwise it only sees the symbol,
but not the vector. What you want is a doseq
loop.
(defn add-elements
[model elements]
(doseq [elem elements]
(.addElement model elem)))
Then you can do:
(doto (DefaultListModel.)
That solved it, thank you!

Ok, I've updated the code with some of Tim's code:

The public functions/macros are:
enabled? [level] [level log-name]
true/false whether that level is enabled for the current namespace
or log-name
log [level message ...]
logs the message either directly

Hi Laurent,
I believe using
(log :fine (expensive-calc))
will do precisely what you describe (not do anything unless
level :fine is enabled, and return nil)
(debug (some-expr)) is intended when you want to leave the logic
precisely as is but display part of the calculation;

Could you give me a two-sentence description, or a pointer to a description,
of what keyword inheritance is? Apparently this is something I haven't
encountered or don't remember...
Thanks a lot.

What's the point of interfaces if you write APIs that require classes?

Tim is correct. The log macro is what you want to use when you're
really just wanting to log something; in that case the message
expression won't get evaluated unless the particular logging level is
enabled.
The debug function is for when you want to execute an expression
regardless, but would
Hmm, I like spy since it doesn't mimic a logging level like debug

Hey Travis,
I just went through your article, worked through your code, tinkered. Great
job. I'm learning Clojure now and these are definitely the types of
articles that make it a lot easier to see how to work with all of the
concurrency mechanisms that the language provides.

I'm learning Clojure, and I like a lot what I've seen so far. Thank

I think it is fair to consider that everything the client of your (public)

of the call to 'doc.
