Ruby CSV with CP932
Ruby is a good language. But little bit unuseful for japanese user include me.
I’ve got often invalid seqence error.
CSV.open(filename, 'r:cp932')
This code is bad.
I found a code in csv.rb below:
@encoding ||= Encoding.default_internal || Encoding.default_external
This line from /usr/local/ruby-1.9.1/lib/ruby/1.9.1/csv.rb.
I tried use only “Encoding.default_external = ‘cp932′”.
Encoding.default_external = 'cp932' CSV.open(filename, 'r')
It works.

Getting MacBook Pro
Now I’m in Japan. I had bought and setuped MacBook Pro 15″ in this new year holiday.
MacBook Pro 15"
I am NOT Mac fan and Jobs believer. I just love UNIX envronments. Actually MacBook is good UNIX laptop.
But I got little trouble after I migrate from old MacBook white by Migration Assistant.
I just wrote and ran a ruby script as usual. I got error “nokogiri not found”. OMG!!
The Ruby 1.9.2 was compiled by me. Migration Assistant migrate compled ruby itself but don’t migrate libraries. sigh…
After setup, I bought 8GB RAM. I use many application, especially VMware use RAM much more.
Cool. I got 4 core CPU and 8GB RAM laptop. My first mobile UNIX has 486 compatible CPU and 2MB RAM. I couldn’t use Emacs 19 because it is too heavey. Thanks for Moore’s Law.
