Here is what I came up with (defmethod print-method java.net.URI [x w]
(print-method (symbol (format "#uri [%s]" (symbol (str x w))
(pr-str (java.net.URI. "www.google.com"))
"#uri [http://www.google.com";
If used with the cljs parser from above, it works. Thanks

Create the atom in a let, in the function - so it's new and isolated

The URIs are coming from a datomic database that actually stores the values
as java.net.URIs. All I'm doing is transferring the query values from the
database to the client. The server uses pr-str before sending back the
results, and the client uses reader/read-string to get the results.

why not just print/send your uris as strings?
you only need a reader tag if you want to read/interpret it in a particular
way at read time in the client. do you want to do this?

You don't actually need gen-class, you can do a fully-non-AOT'd uberjar
and just invoke it with -cp instead of -jar:
$ java -cp myproject-1.0.0-standalone.jar clojure.main -m myproject

Is there any chance a patch to remove all the obsolete :static keywords from
Clojure's core.clj would be accepted? Or perhaps there isn't much point in
doing so?
I've removed :static as an example keyword in the Metadata section of the

Stathis,
That's a very good point. I've been thinking about the usefulness of
returning the errors map in the original map since the errors map itself is
returned as the first element in the call to 'validate'.
To be honest I'm tempted to remove that with the next release, making
validate return

Hi everybody,
I was implementing a skip list, just for fun.
I implemented the list and just to be sure that it were working I wanted to
count how many steps it compute to find a value.
SkipList --> http://en.wikipedia.org/wiki/Skip_list
To do so I was using a atom, and the code looks like this:

Hey Leonardo,
This is very interesting, but I'd like to know whether it's possible to
validate a map that contains an :errors key. Would bouncer overwrite this
with its own :errors key? Should it not be using a fully-qualified keyword
(as in ::errors) to avoid the clash?
Thanks,
Stathis

obviously, you would use 'assoc' in your reducing fn...If your old-map
is rather big then you can start with a transient version of a map and
persist it at the end of the entire operation.
new example:
(peristent!
(reduce-kv #(assoc! % (transform %2) %3) (transient (hash-map)) old-map))
;;% is
you can use reduce-kv...This is exactly its purpose - to be able to
reduce maps without the need of destructuring
example:
(reduce-kv some-fn-with-3-args {} old-map)

I have a map derived from JSON data where the keys are strings. I want to
build a new map from this one, where the new keys are based on integers
extracted from the strings of the old keys by a regex. Not all entries
will be transformed into the new map.

Hi all,
I often find myself wanting to attach meta-data to built-in Java classes
and particularly to the 'String' class. In a text-mining and NLP
context, it is very useful for example to have a dictionary of strings
where each string 'knows' its synonyms...Of course one can get around
that
So take this definition from master:
(def
^{:arglists '([x])
:doc "Return true if x implements ISeq"
:added "1.0"
:static true}
seq? (fn ^:static seq? [x] (instance? clojure.lang.ISeq x)))
static is used twice here. What is / was the difference? Is it correct
to say that it is now just

We're using that technique for both long-running server processes and small

I have question about certain metadata definitions, which I couldn't find a

1. is ^:dynamic the same as ^{:dynamic true}, just a shortcut?

what are the other validation libraries?
