I Try to write a parser for this command line

binoculars-ng --debug process data/test/config_sixs_ruche_flymedv_3.ini 698-734 735-736

But I have this problem

Invalid argument `735-736'

The parser used for this is this one

processOptions :: Parser Options processOptions = Process <$> optional config <*> optional (argument (eitherReader (parseOnly configRangeP . pack)) (metavar "RANGE"))

it use the configRangeP attoparser parser whcih knows how to deal with the string "698-734 735-736"

I guess you must use something like (many (argument ...)).
