Clojurians Log v2

i need to create a breadth first search wrapper using zippers. any ideas?

here's one without a zipper (returns first match of pred)

(defn breadth-first [pred coll] (when (seq coll) (or (first (filter pred coll)) (breadth-first pred (apply concat (filter coll? coll))))))

or - I don't know what a "wrapper" is, so maybe that's totally irrellevant

@abhayarawal: did a quick google-ing and didn’t find anything, should be pretty nice exercise writing it :simple_smile:

here’s my actual problem. http://stackoverflow.com/questions/32729795/shortest-path-using-breadth-first-search-in-clojure

@abhayarawal: do you always start searching from the root?

yes

hm, will try to look into it using zippers, just need to bootstrap a simple test file

thanks!

@abhayarawal: got it working here: https://gist.github.com/darwin/6fbc796aa6a8a17e71b3

the iteration needs to carry some state around, see the bfs-visits example it was more difficult than anticipated :simple_smile:

tested under cljs

thanks darwin. i’ll check it out

Any pointers on how our clojurebot /clj is implemented? I want to take it with me to other room :simple_smile:

Ok, I had to google it. It's verma/clj-slackbot in github :simple_smile:

Hi

component library is using a lot of syntax like (map->Something) - I can’t find any macro "map->” and it is not part of clojure core. What this is ? :simple_smile:

And uncle google doesn’t show any sensible results

Is this is just (map -> …)?

@mr-spock: it's a convention

mr-spock: it’s from defrecord: http://clojure.org/datatypes

Ha - Now I see :simple_smile:

@jcsims: thnx

(find-doc) (doc) did not gave any results
