You should get col and col_1 automatically since it looks for
duplicate column names and makes them unique. Which version of
java.jdbc are you using?

I have an issue with clojure.java.jdbc, in that I want to join two tables
that have columns with the same name. What's happening is that the result
set maps only have the second key-value pair from the result row in them.
Is there some way to alias or namespace the keywords in the results from
cl
Hi,
So I got a working test and it looks like this:
(facts "sets a value for the given key in redis"
(with-redefs [redis/with-conn (constantly "Ok")]
(require '[com.leonardoborges.cache :as cache] :reload)
(fact "with no ttl "
(cache/set "key" "value") =>
timely comment.
you can create and throw it but catching it requires the imported type.
(not withstanding catching the generic Exception on the JVM).
see the link for suggestion/discussion on making this more "uniform" for
clj and cljs:

Hi,
I have some caching code that relies on a macro called 'with-redis' so
while writing my tests I'd like to redef this macro to bypass all of
it's redis connection machinery and just execute a function that does
nothing instead.
Something like this works:
(with-redefs [cache/with-redis (fn [&

Was there a library or some other way to pass ie. maps to functions
so that the order of the params isn't predefined, just in case I want to
skip some passing parameters without actually having to pass some value for
them, I could just refer to which params I'm passing by identifying them

ah nice, never realised that, thank you. still it'd be somewhat more
consistent to import ExceptionInfo:
(throw (Exception.))
(throw (IndexOutOfBoundsException.))
(throw (IllegalArgumentException.))
;; ...there's quite clearly a pattern here, which many are accustomed to
(throw (ex-info "" {})) ;

Clojure's collection functions do a typeof dispatch for JVM types. In a
bootstrapped clojure, that would be solved with protocols.
E.g.
https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/RT
You can create an ExceptionInfo instance easily by using the core fn
`ex-info`. So something like ... (throw (ex-info {:foo "bar"})) works
fine. ~BG

Couldn't clojure.lang.ExceptionInfo be imported by default? That'd surely
help making ExceptionInfo the idiomatic exception to be thrown.

Thank you!
Adding type hints solves the problem. The interop now slightly outperforms
Clojure's get and count.
So how come Clojure's get and count don't incur the reflection penalty?

Try to set! *warn-on-reflection* to true and you'll find out that
there's a lot of reflection going on when using direct java interop.
Try benchmarking (.length ^String sss) and you'll see the difference

I am writing an expensive algorithms in Clojure and while trying to
optimize the code I discovered something that puzzled me. Clojure count and
get functions are much faster on strings than direct interop with .length
and .charAt. On my machine I get the following:

It has been up since October 2012. Not much activity recently but except
for macros,
all the essentials are pretty well covered already.

Even though what Aaron said is correct, I'll just add that with lein2
you can get away with not "installing" your jar in ~/.m2/. Just use the
:resource-paths key in your project.clj and point to a folder with
'orphan' jars...something like this:
:resource-paths ["orphan-jars/*"] ;;all jars un
"clojure-doc.org" ??
OMG, is this new? it seems to have some gorgeous tutorials for
