converting a string into a set
Hello,
My apologies for this newbie question. I couldn't find a way to
convert a string to a set, thus:
"abc" => #{a b c}
Thanks.

Re: converting a string into a set
Hi,
(set "abc")
gives me #{\a \b \c}.
I'm expecting instead: #{a b c}
But thanks,

(set (map "abc"))
(set (map str "Tuba Lambanog"))

Hi Tuba,
Are you quite sure that #{\a \b \c} is not what you want? In Clojure's
notation, a backslashed character [more or less] refers to a
single-character string--something akin to the char type from C. Hence \a is
the character a. On the other hand #{a b c} is a set containing three
Clojure symbols, which is probably not what you want.
(If you want to be using a, b, and c as some kind of identifiers, take a
look at keywords.)

This will produce #{"a" "b" "c"}
I think
(set (map #(symbol (str %)) "abc"))
should do the trick

Re: converting a string into a set
Hi,
I'm clear on what I want ;) (something new to me), but I'm not clear on how
to get there. I'd like to compare str1 and str2, if at least one of the
letters in str1 is in str2. I'm thinking that if I can convert str1 and str2
to sets, then I can use the set intersection operation. It probably doesn't
matter here if the sets contain characters or symbols?

Re: converting a string into a set
In that case you don't need to convert to a symbol...
(set "abc") should be fine...
Using set intersection, something like this is probably what you're looking
for...
(use 'clojure.set)
(if (empty? (intersection (set "abc") (set "cde"))) false true))
I'm sure there's other (better) ways though

Wow, that some function is just what I'd expect from Clojure, simple, straightforward, elegant. How did I miss it? Thanks all.
