CSV with Ruby 1.9.2 and 1.8.7

Ruby
1

Hi all,

I am trying to generate a CSV with the code bellow:

csv_string = CSV.generate(:col_sep => “\t”) do |csv|
csv << [“row”, “of”, “CSV”, “data”]
csv << [“test”, “ação”]
end

But when I try with Ruby 1.8.7 I get the follow error:

ruby-1.8.7-p249/lib/ruby/1.8/csv.rb:326:in `initialize’: can’t convert
Hash into String (TypeError)

And if I try to call the generate methos without arguments, I get a
error too

If I try with 1.9.2 I get the error:

gerar.rb:35: invalid multibyte char (US-ASCII)
gerar.rb:35: invalid multibyte char (US-ASCII)
gerar.rb:35: syntax error, unexpected $end, expecting ‘]’

How to fix this?

First and possibly most important, the CSV implementation is completely
different on 1.8 and 1.9, and I’m not sure that the original 1.8.7
version
supports Unicode at all. So while the TypeError is a little bit
cryptic,
I’m not sure I can provide a better explanation.

The error under 1.9.2 is because you didn’t specify an :encoding in your
call to generate. This works under 1.9.2 on my machine:
csv_string = CSV.generate(:col_sep => “\t”, :encoding => “UTF-8”) do
|csv|
csv << [“row”, “of”, “CSV”, “data”]
csv << [“test”, “ação”]
end

Hi,

I tried set UTF-8 like you, but didnt works with 1.9.2. I got the same
error.

I tried with 1.9.2-head and 1.9.2-preview1
