Hi,
This is another puzzle/exercise based on a very practical need. I could not
find a built in function, hoping something like "colfn" already exists.
Otherwise I wonder about an idiomatic solution. This is self-explanatory
code:
user=> (require '[clojure.algo.generic.functor :as fu])
user=> (require '[me.raynes.fs :as fs])
user=> (defn colfn[col] (fn [a] (fu/fmap #(% a) col)))
user=> (map (colfn [fs/directory?,identity]) (filter fs/directory?(set
(fs/list-dir "."))))
([true "src"] [true "target"] [true ".git"])
user=> (map (colfn {:is-dir fs/directory?, :dir identity}) (filter
fs/directory?(set (fs/list-dir "."))))
({:is-dir true, :dir "src"} {:is-dir true, :dir "target"} {:is-dir true,
:dir ".git"})
My question is, if something like colfn already exists? The idea is to
generate a function of a sequence (vector, list, map) of functions which
would used in e.g. map.
Best,
Andy
