Alternatively parsing the file yourself could be an option. Use FileStream (
http://www.valadoc.org/#!api=glib-2.0/GLib.FileStream ) to open the file and
read each line. Vala, from its close dependency on GLib, includes a regex
library. For an introduction see
http://ewgeny.wordpress.com/2012/04/07/mighty-perl-like-regular-expressions-regex-with-glib-and-vala/
, for details see http://references.valadoc.org/#!api=glib-2.0/GLib.Regex or
you can just use string split (
http://references.valadoc.org/#!api=glib-2.0/string.split )
Writing your own CSV parser can be harder work if you start getting into
details of not splitting quoted values. For a discussion see

Good luck,
