returns a human readable output of the diffs

(println (-> (diff “10\n11\n \n13\n14” “10\n18\n \n19\n14”) (->string)))

creates a Chunk object from map

(create-chunk {:position 1 :lines “hello”}) => Chunk

creates a Delta object from map

(create-delta {:type “CHANGE” :original {:position 1 :lines “hello”} :revised {:position 1 :lines []}}) => Delta

creates a Patch object

(create-patch [{:type “CHANGE” :original {:position 1 :lines “hello”} :revised {:position 1 :lines “world”}} {:type “DELETE” :original {:position 1 :lines “again”} :revised {:position 1 :lines []}} {:type “INSERT” :original {:position 1 :lines []} :revised {:position 1 :lines “again”}}]) => Patch

returns a set of diff results

(diff “10\n11\n \n13\n14” “10\n18\n \n19\n14”) => [{:type “CHANGE”, :original {:count 1, :position 1, :lines “11”}, :revised {:count 1, :position 1, :lines “18”}} {:type “CHANGE”, :original {:count 1, :position 4, :lines “13”}, :revised {:count 1, :position 4, :lines “19”}}]

creates a summary of the various diffs

(summary (diff “10\n11\n \n13\n14” “10\n18\n \n19\n14”)) => {:deletes 2, :inserts 2}

takes a series of deltas and returns the revised result

(patch “10\n11\n \n13\n14” [{:type “CHANGE”, :original {:count 1, :position 1, :lines “11”}, :revised {:count 1, :position 1, :lines “18”}} {:type “CHANGE”, :original {:count 1, :position 4, :lines “13”}, :revised {:count 1, :position 4, :lines “19”}}]) => “10\n18\n\n\n19\n14”

creates a summary of the various diffs

(summary (diff “10\n11\n \n13\n14” “10\n18\n \n19\n14”)) => {:deletes 2, :inserts 2}

takes a series of deltas and restores the original result

(unpatch “10\n18\n\n\n19\n14” [{:type “CHANGE”, :original {:count 1, :position 1, :lines “11”}, :revised {:count 1, :position 1, :lines “18”}} {:type “CHANGE”, :original {:count 1, :position 4, :lines “13”}, :revised {:count 1, :position 4, :lines “19”}}]) => “10\n11\n \n13\n14”
