Hi Folks,
So, I have a search string, for example "rabble". And a map which
contains keyword keys, and vectors of strings as values:
(def players
{
:amit ["a" "b" "c"]
:roger ["rabble" "x" "y"]
})
Is there an idiomatic way to search for "rabble" in the vector values,
then return the keyword tha
Try this...
(second (first (filter (comp (partial some #{"rabble"}) val)
players)))

Oops! Slight mistake
(ffirst (filter (comp (partial some #{"rabble"}) val) players))

Thanks for the suggestions.
I think since the original version short circuits when it finds a
result (using "some"), that's probably what I have to stick with.
One thing I didn't mention in the original problem statement is that
my "players" map can be large.
Again, thanks for the ideas.

Sean's solution does as well.

This shaves 7 characters off Sean's solution and short circuits just
as fast:
(some #(and (some #{"rabble"} (val %)) (key %)) players)
Happy hacking!

lambdatronic: That's a very slick use of "and" in the outer "some!" I
quite like that.
Thanks to all again.
