Ruby 2.0 release candidate one

Hey, the first Ruby 2.0 release candidate has been released! These days, I've been using rbenv to manage my Ruby installations, but I don't see rc1 in ruby-build yet. No matter, it's easy to add it to rbenv without ruby-build. First, fetch the source code and untar it.

$ wget http://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-rc1.tar.bz2
$ md5sum ruby-2.0.0-rc1.tar.bz2 
24cebdda11e01ff4889ac983cd7dc02c  ruby-2.0.0-rc1.tar.bz2
$ tar xf ruby-2.0.0-rc1.tar.bz2
$ cd ruby-2.0.0-rc1

Since rbenv uses the directory name to determine the versions, we just adjust our prefix in the configure step of the usual configure-make dance.

$ ./configure --prefix=$HOME/.rbenv/versions/2.0.0-rc1
$ make
$ make test
$ make install

Now a rehash will pick it up.

$ rbenv rehash
$ rbenv global 2.0.0-rc1
$ ruby -v
ruby 2.0.0dev (2013-01-07 trunk 38733) [x86_64-linux]

Oops! This ruby doesn't seem to know it's the release candidate, but it is.

Note that they plan on one more release candidate and then Ruby 2.0 will be released!

We will release 2.0.0-rc2 in early February, and 2.0.0-p0 at 24th Feb. (the 20th anniversary of Ruby).

Keyword arguments! Lazy Enumerators! Onigmo! Exciting times!
