Exactly like Ticket #460:
status changed from new to closed
resolution set to invalid
what does it mean: resolution set to invalid?

It means that in Ruby 1.9 the old CSV library was replaced by the
FasterCSV code base. FasterCSV (now renamed to CSV in 1.9) has a
slightly different interface. The call above would need to be
translated to that new interface:
CSV.parse(a, :col_sep => “,”)
In this case though, it would be better to leave out the separator,
since it is the default.
Hope that helps.

Ok, I did not understand something!.
I have updated my ruby from 1.8.6 to 1.9.1
I used with ruby 1.8.6
FasterCSV.foreach(fichier, :col_sep =>‘;’, :row_sep =>:auto) do |ligne|
where ‘fichier’ in the name of my file
and all is ok
Now, I have to change this line to use my program with ruby 1.9.1:
CSV.foreach(fichier, :col_sep => “;”) do |ligne|
gives
/usr/local/lib/ruby/1.9.1/csv.rb:1329:in initialize': can't convert String into Integer (TypeError) from /usr/local/lib/ruby/1.9.1/csv.rb:1329:in open’
from /usr/local/lib/ruby/1.9.1/csv.rb:1329:in open' from aipsa2.rb:63:in ’
I check http://ruby-doc.org/stdlib/libdoc/csv/rdoc/index.html
however no example is given with “;” separator.
Thank you for help

Very little changed with CSV between 1.9.1 and 1.9.2 and I expect it to
work on the lower version too.

Yes, it works ! 
I think it’s time to take a break.
Thank you very much for your time

Your example works fine for me with Ruby 1.9:
$ echo ‘1;2;3’ > data.csv
$ ruby -v -r csv -e ‘CSV.foreach(ARGV.shift, :col_sep => “;”) { |row| p
row }’ data.csv
