Looping over types of pages in Middleman with sitemap + regex.

gistfile1.md

Middleman doesn't yet support multiple blogs, so on my portfolio, I needed a way to loop through my "work" items in a reliable way. I didn't want to have to mess with a bunch of code just when I was adding a new project to the mix. Thanks to Middleman's sitemap feature, and a little Googling, I figured out a way. In Haml:

- sitemap.resources.each do |page|
  - if page.url =~ /^(\/work\/)/
    =link_to page.data.title, page.url

Basically, this loops through every page in the sitemap and filters out everything that doesn't contain the string in the regex. The string I'm looking for here is "/work/". Edit accordingly, and remember that forward slashes (these guys: /) must be escaped with a backslash (one of these: ).

And in ERB:

<% sitemap.resources.each do |page| %>
  <% if page.url =~ /^(\/work\/)/ %>
     <%= link_to page.data.title, page.url %>
  <% end %>
<% end %>

I have a fairly comprehensive Middleman blog tutorial over this way. Check it out.
