Hi Jaap, your CSV library is used in the Hackage2 project. I found that backup and restore does not work with a pristine state, and the reason seems to be a problem with your library: It either adds unnecessary newlines or interprets empty lines at the end of the program for no apparent reason: Prelude Text.CSV> (parseCSV "name" . printCSV) [] Right [[""]] Prelude Text.CSV> (parseCSV "name" . printCSV) [[]] Right [[""],[""]] Prelude Text.CSV> (parseCSV "name" . printCSV) [[],[]] Right [[""],[""]] Prelude Text.CSV> (parseCSV "name" . printCSV) [["hi"],["ho"]] Right [["hi"],["ho"],[""]] Prelude Text.CSV> (parseCSV "name" . printCSV) [["hi"]] Right [["hi"],[""]] Prelude Text.CSV> Is that easy to fix?
