Will all the total lines and slocs be aggregated at repository root level ?
That is certainly feasible in the future. Right now, only files have document data in the Lucene index. To store aggregated num-lines and LOC, it will be necessary to store Lucene data for directories — but without conflicting with the existing queries that all assume only file-level data.
One straight-forward idea would be to add Lucene "documents" for directories with wholly-separate fields so that these new documents never appear in current queries. Of course it would also be necessary to write an aggregator that runs at the appropriate stages.
