Ruby 1.9 # coding: utf-8

Ruby
1

I am trying some ruby 1.9. taste for the first time and I have got to
this new behaviour. Since my location is in Estern Europe, most of my
source files are coded in utf-8. I have found out that I should use #
coding: utf-8 if I want to omit nasty “rubyArchiveTesti.rb:82: invalid
multibyte char (US-ASCII)” error.

Where can I set that all my source files are encoded in utf-8, since I
don’t like the idea of editing them all.

-Ku does this but it’s not recommendable. If your code needs to run
on any other computers, it would need to be run with this flag.
The source encoding magic comments are just a reality of Ruby 1.9
based development, and it seems that your problem could be solved by
better settings in your editor to automatically add this line for you.

foo.rb:

p ENCODING

$ ruby19 foo.rb
#Encoding:US-ASCII
$ ruby19 -Ku foo.rb
#Encoding:UTF-8

You should get to like it. It’s only 1 line per file. Image that
someone with differencts locale wants to use your file. He shoulnd’t
care what encoding did you use.

If you are too lazy to write it by habd you can write some script
which do that for you ;).

It’s my first day and I was suppose to love it. But almost none of my
programs work as before.

Why do you expect they should? Ruby 1.9 represents a completely new
generation of Ruby, and had a whole year of a ‘testing period’ before
it’s first stable release. If you don’t pay attention to what’s
going on, and then expect something to ‘just work’, you’re asking for
trouble. That said, although there are minor tweaks that need to be
made to most Ruby 1.8 based software, it’s normally a quick process to
get things running on Ruby 1.9.

I have just realized that reading file takes about 50x times more on my
Vista then in 1.8.6. (on XP also). Lets go bug reporting.

I’ve been working on character encoding documentation for both Ruby
1.8 and Ruby 1.9 on my blog:

I haven’t got to the 1.9 stuff yet, but I promise it’s coming…
