Yes, "second Clojure book" is exactly what this book aims to be.
Thanks for the overwhelming response, guys!

Hey Francesco,
crossclj is a great project. I use it a lot and it’s actually the one tool that
keeps references up to date. However, it’d be great if the source code is open
sourced.

Hi!
Today I fall into:
java.lang.RuntimeException: java.lang.ClassFormatError: Invalid method
Code length 88118 in class file xxx$eval304 (xxx.clj:274) (xxx.clj:3)
problem.
The reason is that I tried to use data as code and just execute the slurped
AST in order to produce another form of cod
Hi,
I'm trying to remove an element from nested data structure (nesting in
unknown, so I'm trying to come up with a generic solution:
(def z [
{"a" {"b" 1 "c" 2}
"children" [{"a" {"b" 3 "c" 4}
"children" []}]}
{"a" {"b" 5 "c" 6}
The modify function
(defn modify [loc]
(-> loc z/remove))

Hussein,
Making this change to the zipper definition:
(z/zipper #(get % "children") #(get % "children") (fn [p c] (assoc p
"children" c)) {"children" z})
looks like it'll do the right thing here.
Take care,
Moe

Hi,
AFAIK the only way to create (just) a source (or sink) is:
(def my-source (s/source-only (s/stream ...)))
This results in creating a stream and then wrapping it with a SourceProxy.
We don't keep a reference to the stream and the SourceProxy doesn't allow
taking.
But if I'm not missing somet
Thanks a lot Moe for your help. I always appreciate your patience and
skills.
Would you explain why your zipper works in this case?
Thanks again.

Don't compile it, use the EDN reader instead.
You can't do functions and that sort of thing, but the data structures
will work.

For the sake of simplicity. I've just define functions or macros which can
appear in the data structure and simply call eval on that structure. The
defined functions and macros has side effect which is println to the binded
output stream.
The example structure looks like this:

Hussein,
The previous example (from your other thread) worked, as it happened
to involve removing the parents of nodes which match the predicate -
the make-node function I'd given you worked more or less by accident
in that one specific case, but not here. Apologies if you lost time
due to my mis

extending the Ring metaphor: building up the functionality of the web

That's misleading. In the case of convention function names, (index, show,
create), there's default :route metadata that is used automatically ... the
docstrings are merely supplying a reminder.
This is described in the "Getting Started" page:

Got it, thanks.
I think you still need to prepend ^'s to the metadata.

Pretty is a library for (among other things) printing Clojure stack traces,
prettily.
Changes in 0.1.19:
Print a blank line before the exception output, when reporting a
clojure.test exception.
Previously, the first line was was on the same line as the "actual:" label,

In the first two cases, the metadata is actually applied to the bar symbol

latter case, the #'bar Var gets the metadata d

A workaround for integer types is totally trivial:
(defn my-numerator [x]
(if (ratio? x)
(numerator x)
x)
)
(defn my-denominator [x]
(if (ratio? x)
(denominator x)
1)
)
