Patch: Code


clojure.inspector/inspect-table gives up when first element of coll is nil. The patch provided is rather trivial...instead of blindly choosing the first element (which might be nil), it would be more convenient to choose the first element that is NOT nil and use its keys for columns...a similar issue exists with clojure.pprint/print-table where the keys of the first element are used (if not provided explicitly). The same is not true for 'inspect-table' though. As a result, one cannot 'inspect' a collection of maps where the first element is nil. My (trivial) patch looks for the first element which is NOT nil and uses its keys instead. Maps have to have the same length anyway so no problems there...

clj-1020-inspect-table-skip-nil-rows-patch1.txt of July 12, 2012 is identical to inspector.patch of July 2, 2012, except it is in the desired git format. Proper attribution is given to author Dimitrios Piliouras in the patch.

I literally copied the contents of "clj-1020-inspect-table-skip-nil-rows-patch1.txt" and pasted them on "clj-1020-inspect-table-skip-nil-rows-patch2.txt" only changing:

(some #(when-not (nil? %) %) data)
(some identity data)

much nicer/cleaner and faster since we skip the internal nil-test.
