(with-open [r (reader "FILE")] (str-join ", " (take 5 (drop 5 (line-seq r))))) This still does the work of finding all the \ns that you skip, of course. Linewise navigation of a file is not as fast as seeking to byte offsets. > I can do this in java using traditional java way by using > LineNumberReader's setLineNumber(int lineNumber) but i'm not sure how > to interweave this in with clojure's file sequence operations. (with-open [#^Reader r (reader "FILE")] (with-open [lr (java.io.LineNumberReader. r)] (.setLineNumber lr 5) ;; Your code here. ))) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
