Add ability to have @ mentions in xml/json feeds

[brandontreb]

Im currently using this plugin to handle mentions for micro.blog. I noticed that it filters out everything that's not a "page". Is there a way to have the plugin convert the @ mentions on a feed.json and feed.xml page?

Thanks so much!

I needed this as well, and it looks like altering this plugin as-is is harder than it looks due to the need to escape the output for XML documents, so I took a different approach. I ripped out the guts of the plugin and turned it into a liquid filter:

Just drop this in your _plugins folder (and add the "html-pipeline" gem to your Gemfile) and this creates a new "replace_mentions" liquid filter that you can use to do something like this:

{{ content | replace_mentions | xml_escape }}

Because it's a filter, this is a lot more flexible, as you can apply it at your discretion. In my case, I apply it in the default layout as well as in the XML template that I use for generating my RSS feed (which I then pass into an xml_escape pass).

Because I basically gutted the existing plugin, this uses all the same configuration settings and so forth, so it should drop in cleanly and can even be used side-by-side with the plugin.
