c - LXR 用于 Ruby 解释器？

Question

我正在尝试track down a bug caused by the intersection of MRI 1.8.7 and libxml-1.1.3 ，并且我需要在 Ruby 解释器本身的代码库中进行一些挖掘。 SVN browser用途有限；我真正想要的是使用 LXR ，它超链接 C 代码库以便于导航，例如http://lxr.linux.no/perl+perl-5.10.1/utf8.c

我当然可以在我的机器上设置 LXR，但是有人知道是否有用于 Ruby 的公共(public) LXR？谷歌不是很有帮助:http://www.google.com/search?ie=UTF-8&q=lxr+ruby

Answer 1

我还没有找到用于 MRI 的公共(public) LXR，所以我在我的机器上安装了一个。以下是在 Ubuntu 10.10 上执行此操作的方法:

: 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
