I have map of item names and vectors of vectors which store categories which the key string item are in. I am trying to parse this map into a couple hiccup defpartials which then can display them organized by category.
What I think I need to do is parse the map once to make a set of all possible categories and sub categories. Once I have that I can iterate that and filter all matches from the main map to get the proper key strings.
How can I go from the map below, to a set of all main and sub categories? Once I have that set, how do i use it query the original map by values not by key?
thanks for any help!
(def ITEM-CATEGORIES
{ "thingy" [["CatergoryA" "SubcategoryA"]]
"thingy2" [["FFT"]]
"thingy3" [["Generators" "Chaotic"]]
"thingy4" [["Analysis" "Pitch"] ["MachineListening"]]
"thingy5" [["Multichannel" "Ambisonics"]]
}
goal in sudo code
(generate-hiccup-partial (create-set-of-unique-categories ITEM-CATEGORIES) ITEM-CATEGORIES)
....
(defpartial generate-hiccup-partial
[categories map]
;; hiccup code
(in-each-sub/main-category-get-keys-by-value categories map)) ;; return a list of all keys with the same categories
I do not know what a defpartial is, but this will transform that map:
(defn xform [ic]
(reduce (fn [result [k [vs]]]
(reduce (fn [r v]
(assoc r v (cons k (r v)))))
result vs))
{} ic))
user=> (xform ITEM-CATEGORIES)
{"SubcategoryA" ["thingy"], "CatergoryA" ["thingy"], "Ambisonics" ["thingy5"],
"Multichannel" ["thingy5"], "Pitch" ["thingy4"], "Analysis" ["thingy4"],
"Chaotic" ["thingy3"], "Generators" ["thingy3"], "FFT" ["thingy2"]}
