Redirecting Folders in Middleman's config.rb

I'm using the static site generator Middleman to build my site. We currently have landing pages that we proxy via config.rb as such:

# landing page template directories to redirect
landingpage_seo_templates = Dir['source/landingpages/seo/*.erb']

# point all landingpage/seo templates to the root
landingpage_seo_templates.map! do |tpl_name|
  tpl_name = File.basename(tpl_name).gsub(/.erb$/, '')
  proxy "/#{tpl_name}/index.html", "/landingpages/seo/#{tpl_name}.html", :ignore => true
end

This points all of the files in a directory from /landingpages/seo/{filename}.erb to the /{filename}.erb when the site is built. However, this doesn't work for sub-folders.

My question is how would I modify this script to render the sub-folders. For examples I would like files in /landingpages/seo/foo/{filename}.erb to render to /foo/{filename}.erb

I know how to do this via .htaccess, however I'd like to learn how to do this via config.rb.

Thank you in advance.

Solution

If you modify your file pattern ...

landingpage_seo_templates = Dir['source/landingpages/seo/**/*.erb']

... you should get all erb templates in the seo tree.

You then need to modify the tpl_name computation (there probably is a smarter/shorter way for that):

# point all landingpage/seo templates to the root
landingpage_seo_templates.map! do |tpl_name|
  tpl_name = tpl_name.gsub(/.erb$/, '')
  tpl_name = tpl_name.gsub(/source\/landingpages\/seo\//, '')
  proxy "/#{tpl_name}/index.html", "/landingpages/seo/#{tpl_name}.html", :ignore => true
end
