I think the easiest solution for me is to just use clj-http to get the
content of the "leaf" pages and then hit 'em with a regex. It's not pretty,
but, then again, neither is the tagsoup documentation.

If you really care about performance then I would use a macro for code
generation and do something the following:
(defmacro appendfunc
([m keys sb]
`(do
(.append ~sb (~m ~(first keys)))
~@(for [k (next keys)]
`(do
(.append ~sb \,)

You are right: I was not looking correctly. :-(
In a way it
Basically same way you profile java, I usually use jvisualvm, if you feel
like shelling out for yourkit that can be nicer.

You can probably omit try and throw to achieve the same effect.
(let [ste# (aget (.getStackTrace (Exception.)))]
..)

Deon,
This is outstanding. I experimented with a similar approach last summer, but
struggled with a couple of things. First was what to use for the event store.
I considered a few options, like using Datomic for that as well (I.e. annotate
transactions and treat the sequence of transactions
Clojure doesn't give you direct access to the name of the function you're
defining. However, you could use a macro to get that. Here’s one way. This
macro binds the strange symbol %0 to the symbol naming the current function.
;; %0 is bound to the function's symbolic name within the function
What is the best way to profile Clojure? I tried a reduce doto thing but it was
way slowe than apply str. would love to know why.

Unless I'm mistaken, in the output you show:
Exception ERROR: round [:high|:low|:normal] user/round
(repl-startup.clj:30)
"user/round" is the name of the function, as desired.

Well, one of the many reasons, that clojure is faster than bash is, that
during compilation, code is divorced from the original source symbols.
That means you can only access information about the original source that
you, or some library code you use, put in there for you.
Jony stated correctly,

Ah, I see. I don't know how to do that. But, the function name should be in
the stack trace associated with the exception. Is there a particular reason

That is not what I meant. I have the following function:
(defn round
([x] (round :normal x))
([mode x]
(let [fn (case mode
Good catch; Thanks for correcting me.

Enlive by default uses tagsoup to parse html and can also use jsoup, so I'd
start with parsing options for those. It can also be used with other
parsers, provided you can get them to generate clojure's xml map format.

There might be a neater way, but

In Bash I use the following construct:
printf "${FUNCNAME} needs an expression\n"
In this way I do not have to change the print statement when the name of
the function changes. Is something like this also possible in clojure?

It was not a non-breaking space (those I see), but something like it, with
code #x200b. Af
"Unable to resolve symbol: in this "
I get this error when I have a non-breaking space in my code :

A Clojure fn is an Object, but Math's ceil method is not an Object. The
Java-Interop notation for static methods, eg (Math/ceil...), papers over
this difference. If you want to manipulate something like Math/ceil as a
Clojure fn, you can wrap it in one such as your round-high.
