In the last few months I did a lot of work concerning imports.
Using the Sequel Toolokit I was able to treat every query row as a hash and the whole thing has been working out pretty good so far.
However I always needed to do conversions on the hashes (map keys to a different name, concatenate values etc....). Therefor I implemented several mapping classes that helped me with that but was never quite satisfied with the implementation.
Then I stumbled upon ActiveImporter and I knew: "That's exactly what I need".
Unfortunately ActiveImporter is designed to import table data into models.
I need to transform array of hashes into other array of hashes.
That's why I built morfo. It uses a similar DSL as ActiveImporter to do just this.
But I will continue to use it and implement new features on the way.
