LXRing Ruby

As those of you who follow me on StackOverflow already know (Anyone? Bueller? Anyone?), I need to browse the source code of the Ruby interpreter. Getting no immediate answer, I set up LXR myself:

: josh@josh; cat /etc/issue
Ubuntu 10.10 \n \l
: josh@josh; sudo aptitude install apache2 lxr
: josh@josh; sudo vim /etc/apache2/sites-available/default
: josh@josh; tail -6 /etc/apache2/sites-available/default
Alias /lxr /usr/share/lxr

Options All
AllowOverride All

: josh@josh; sudo vim /usr/share/lxr/http/.htaccess
: josh@josh; sudo cat /usr/share/lxr/http/.htaccess

SetHandler cgi-script

: josh@josh; sudo mkdir -p /usr/share/lxr/source/1.8.7-p334
: josh@josh; cd /usr/share/lxr/source/1.8.7-p334
: josh@josh; sudo tar xvjf /tmp/ruby-1.8.7.tar.bz2
: josh@josh; sudo mv ruby-1.8.7 ruby
: josh@josh; sudo vim /usr/share/lxr/source/versions
: josh@josh; sudo cat /usr/share/lxr/source/versions
1.8.7-p334
: josh@josh; sudo ln -s /usr/share/lxr/source/1.8.7-p334 /usr/share/lxr/source/defversion
: josh@josh; sudo genxref ruby
