Hello, I recently created a module for encoding and decoding numerical arrays to strings, in the form of "1,4,10-29", with duplicates being supported. It works by optionally exporting a selection of functions including encode_array, decode_array, validate_encoded_array, add_encoded_arrays, subtract_encoded_arrays. Probably will add another function to remove duplicates and allow greater flexibility with the format of the string in the future. Tempted to possibly add more set logic - though don't want to make it overlap Set::Scalar too much.
It's main uses would be for display and user entry. For instance in a web application it could be used to specify a collection of ID numbers in a shortened form, rather than having to select them all individually. I was thinking of calling it Number::Collection - but wasn't sure if that's appropriate or not. I've already written the bulk of the module and a series of tests and POD for it, which I can show if need be. Best wishes -- K. J.
