I guess you can now get c.j.jdbc and put (time ...) wrappers in the
call path in it to see where is the time mostly spent.

Thanx. I wanted to eliminate reflection as the potential culprit.

He got this far:

Yeah, outputting symbol style
The problem existed from Friday at about 10AM until Saturday morning
when it was found and fixed. It only occurred when compiling something
in advanced mode for the first time, which is probably why it was
missed. There are some tests in place but we haven't yet got to the
point where everything is
Hi Arthur,
I think thos would make a reasonable addition. If you'll make a JIRA ticket
in the backlog, I'll see if I can push it forward. Ultimately, it will be

Hi Martin,
It's definitely a concern, keeping track of map keys and finding mis-typed
names. I always use keywords instead of accessor functions, though. If there
were functions, it's just one more thing to rename when refactoring.

Hi Shoeb,
At this point, we probably need more data to give a meaningful answer.
Different core data structures and different coding conventions can mean
that "the same code" in Clojure and Java will behave quite differently.
Try profiling your Clojure code with a Java profiler such as VisualVM
hi!
Is there a tool available that does indentation of clojure code and does not
depend on an editor/IDE?
we work on the same code together with different editors
(eclipse+counterclockwise and emacs). We often reindent the other's code
what leads to changes when we merge our commits with git.
Alas, the current bug is in the head of master, and is unrelated to either
advanced-mode or the absence of the destination file.
Rather it appears to be due to the fact that the quick start doesn't pass an
output file to cljsc, but rather redirects stdout to the destination file.
When that occ
I have suffered the exact same problem in large projects. Clojure's
associative style is extremely powerful and simple, together with powerful
sequence handling functions you could hurt yourself. The fact that it's
really easy to put together nested maps to represent your models, shouldn't

Oops. I thin
Sorry. I didn't notice that you were compiling a single file. That is
a different problem from the one I was referring to.
You were right about the cause as well. That particular problem is now
fixed.
Thank you for reporting it.

Perhaps we can put these in core.incubator for now so they have a place
to live in the 1.3 world. The function for this library is the staging
of things that are destined for core itself, so it might not be a bad idea.

Is it possible to use macros within ClojureScript without having to
fully reference them?
Right now I have
(ns hack.cljs.hello
(:require-macros [d3-macros :as d3m]))
and have to use the form
(d3m/my-macro ...)
Ideally I could just say
(my-macro ...)
Is this possible?
Bonus
Great.
BTW, are these warnings expected:
$ cat > hello.cljs
(ns hello)
(defn ^:export greet [n]
(str "Hello " n))
$ bin/cljsc hello.cljs '{:optimizations :advanced}' > hello.js

Those warnings have been around for a couple of weeks now. In that
sense they are expected. I will see what I can find out about them.

Wouldn't string.incubator be better, for possible inclusion in
clojure.string (rather than core.incubator for clojure.core). Seems more
consistent... Otherwise things will be moving from c.contrib.foo to
c.core.incubator and then (possibly) to c.foo...

These warnings should now be gone (thanks to Fogus).

Hello,
I’m doing a word stemmer for a non-English language. A stemmer parses
a word into its word parts: prefixes, roots, suffixes. The input word
is at least a root word (English example would be ‘cloud’), but can be
any combination of prefix(es) and a root (e.g., 'pre-nuptial'), or a
