给Octopress的RSS输出中添加文章作者信息

Octopress自带的RSS模版中没有包含文章作者信息，而是只包含了网站作者信息。考虑到博客经常只是一个人写作，同时文章作者随RSS显示，更常用一些，所以我对默认的RSS模版做了一点改动，让它支持了文章作者信息的输出。其实改动相当简单，默认情况下就一个 atom.xml 文件，该文件位于 source/ 目录下。改动如下：

atom.xml输出作者信息 (atom_author.diff) download

diff --git a/source/atom.xml b/source/atom.xml

     <content type="html"><![CDATA[{{ post.content | expand_urls: site.url | cdata_escape }}]]></content>
   </entry>
   {% endfor %}
 </feed>

其实很简单，就是将全局的作者设定移到文章条目的设定中，这样设置的作者信息就成为了文章的属性。对于曾经给Octopress添加过RSS2.0支持的站点¹，还需要相应修改一下 source/ 目录下 rss.xml 文件：

rss.xml输出作者信息 (rss_author.diff) download

diff --git a/source/rss.xml b/source/rss.xml
index 435f17f..044e52f 100644

    </item>
    {% endfor %}
  </channel>
 </rss>

同样，只需在文章描述段中加入作者信息的属性即可。修改好文件保存之后，再次运行 rake generate 就会发现rss文件已经正确更新了。

就添加一句 include post/copyright.html ，不过要注意是在CDATA段中。 rss.xml 一样处理：

    {% endfor %}
  </channel>
 </rss>

轻松搞定，效果就是我博客现在的效果。
