The def was for legibility (or I was going for legibility). Speaking
of redefing, is there a way to block a redef so I or someone else
doesn't monkey-patch a function?
You can set a validator on the Var to prevent accidents. However,
someone who really wants to redefine a function can just

One problem is that the compiler can't keep track of line numbers in
the REPL (or SLIME).

The following will give you a fresh user namespace:

(remove-ns 'user)

Take a look at the dependency management tools. Most open-source
Clojure projects use either Maven and Leiningen. Both use the same
dependency model and provide similar capabilities for starting a REPL
with the classpath configured automatically.

I am having trouble with the re-seq regular expression form. I am not
an expert on regex, so this is probably part of my problem. I have a
k12 text file, basically it is hex broken up by '|' . I would like to
grab all the hex between two hex numbers (sample text below). For
example, I might

Hi,
you have to escape the |.
user= (re-seq #49\|00\|([0-9a-f|]+)\|a4\|ff a5|a5|49|23|49|00|12|
fc|5e|a4|ff|a7|49|00|ee|d3|a4|ff|ae)
([49|00|12|fc|5e|a4|ff|a7|49|00|ee|d3|a4|ff 12|fc|5e|a4|ff|a7|49|00|
ee|d3])
However this will be greedy...

Hi all,
I would like to announce clj-tagsoup, a simple cl-html-parse workalike

Hi,
Is it possible to remap the name of a class or package import?
Ideally
I'd like to say something like (import [[java.util :as ju] ArrayList
List]) and then use (ju.ArrayList.) to refer to the class. I recall
reading Rich doesn't like auto-imports of all classes in a package or
of renaming
The result is a little bit strange still, since I am getting
dupliates. First, it returns the string I want
49|00|12 12|a9|a4|ff
but then it also returns the same string without the first and last 4
characters, e.g.
12|12|a9|
Also, how come I don't need to escape the | inside the
Parentheses capture - anything that matches a parenthesized portion of
a regular expression is returned as part of the result of the match:
user= (re-seq #a(.)c abc)
([abc b])
If you don't want that behavior, you can use the special non-capturing
syntax, (?:...):
user= (re-seq #a(?:.)c abc)
Addendum: I highly recommend Jeffrey Friedl's book
_Mastering_Regular_Expressions_ if you want to learn how to use
regexes well. There are also a number of introductions/tutorials
online, but I'm not familiar enough with them to recommend any.

The labrepl now has much better getting started instructions, thanks
to everyone who pitched in. But this begs the question: Why hide the
getting started instructions in a single project? So, I am working to
create definitive instructions for getting started with Clojure in a

thx that works great! i guess I can also just leave out the
parenthesis all together.
but, what if i wanted just the portion inside?? the duplicate I
wanted to get rid of?
also any way to return the sequence without all those bars or do i
have to use a seperate regex and or filter?

Leaving out the parentheses changes the meaning because they group as
well as capture. #a(b|c)d matches either abd or acd. #ab|cd
matches either ab or cd.
