I'm sure this must have come up before, but I'm having trouble searching for it. The docs for Text::CSV_XS say,

A CSV string may be terminated by 0x0A (line feed) or by 0x0D,0x0A (carriage return, line feed).

Unfortunately, some Mac format files terminate their lines with a sole carriage return (\r) and this is breaking our automated file processor which uses Text::CSV_XS. We can run mac2unix (or similar) on the file and that works fine, but we need a way to detect and deal with Mac files in an automated manner. Some ideas are:

  1. Read the first few KB of the file and look for lone \r's. If there are some, run mac2unix on the file.
  2. Use one of Perl's new-fangled IO layers/filters to deal with it. I'm not familiar with the new IO stuff so I don't really know where to begin looking.
  3. Use some option in Text::CSV_XS which I accidentally overlooked. (Oops.)

Thanks for your help.
