for macro expects each pair to be either binding-form/collection-expr or one of known modifiers (:let, :when, :while).
Here: plan (keyword (first l)) you give a pair of binding-form and keyword (which is really impossible to iterate over). If you meant let-binding for plan, dec, min and long, use :let modifier (you can find example in documentation - http://clojuredocs.org/clojure_core/clojure.core/for). 2014-08-30 16:47 GMT+03:00 gvim <gvi...@gmail.com>: > I have a long function which produces `list-of-lists` : > > (("Sun" "21" "li" "13" "201.2139410") > ("Moon" "11" "le" "21" "131.3457459") > ......) > > .... before entering a list comprehension (simplified for brevity): > > (defn calc ....... > (let [ ..... > ....... > list-of-lists (map #(rest (first %)) results)] > (for [l list-of-lists > plan (keyword (first l)) > deg (Integer/parseInt (second l)) > sign (signs (keyword (first (rest (rest l))))) > min (Integer/parseInt (second (rest (rest l)))) > long (Float/parseFloat (last l))] > {:deg deg :min min :long long}))) > > When I call the function I get this error: > > IllegalArgumentException Don't know how to create ISeq from: > clojure.lang.Keyword clojure.lang.RT.seqFrom (RT.java:505) > > I've tested all the bindings in the repl and they produce the desired data > so it seems the final construction of the map is where the problem lies. > > gvim > > > -- > You received this message because you are subscribed to the Google > Groups "Clojure" group. > To post to this group, send email to clojure@googlegroups.com > Note that posts from new members are moderated - please be patient with > your first post. > To unsubscribe from this group, send email to > clojure+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/clojure?hl=en > --- You received this message because you are subscribed to the Google > Groups "Clojure" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to clojure+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- Kind regards, Alexey S.
