So I am converting some Ruby code I have into CLojure for practice/fun and I
am having trouble finding info via Google.
I want to take something like this from Ruby and do it in Clojure:
DATE_REGEX = /^\s*(\d{4})\s+(\d{1,2})\s+(\d{1,2})/
token =~ DATE_REGEX
[$1, $2, $3]
So far my best guess

Clojure uses the same regex style as Java, so you'll need to search
for information on Java regexes rather than Clojure regexes.

Here is one way:
user= (import 'java.util.regex.Pattern)
java.util.regex.Pattern
user= (def p (Pattern/compile mon|tue|wed|thu|fri|sat|sun
Pattern/CASE_INSENSITIVE))
#'user/p
user= (re-find p I have a dentist appoint on Monday morning, so you'll
need to take the kids to school.)

i think you want to do something like this:
(let [_ year month day] (re-find date-regex line))

I see. So I may have to use some kind of clunky syntax instead of a nice
$1, $2, $3 syntax. I can handle that I guess :)
Thanks.

A blog entry I read (and now can't find) mentioned being able to use syntax
like (?i) to do the ignore case.

For accessing groups in a match, you can use (re-matches). It will
always give the full match as the first element though:
user= (re-matches date-regex 2011 1 13)
[2011 1 13 2011 1 13]
So to replicate the Ruby code's behavior maybe you'll just want (rest
(re-matches date-regex line)).

Hey, it's a Lisp! You can use almost any syntax you want. How about %1, %2, %3:
(defn
bah! good catch.
(let [[_ year month day]] (re-find date-regex line))
fixed!
