Subject: browsing gem docs


This little script generates a simple web page containing a table of
(name, title, link-to-rdocs) for each installed gem. Could something
like this be incorporated into gem so that each time a gem is installed
you get a nice links page?


#!/usr/bin/env ruby

require "amrita/template"
include Amrita

Dir.chdir "/usr/local/lib/ruby/gems/1.8/doc"

tmpl = TemplateText.new <<END
<table border="1">
  <tr><th>Name</th><th>Title</th><th>Gem Docs</tr>
  <tr id=table1>
    <td id="name"></td>
    <td id="title"></td>
    <td><a id="gemdocs"></a></td>
  </tr>
</table>
END

links = Dir['*/rdoc/index.html']

linkdata = links.map do |link|
  {
    :name     => link[/(.*?)\//,1],
    :title    =>
File.open(link).grep(/<title>/)[0][/<title>(.*?)<\/title>/,1],
    :gemdocs  => a(:href=>link) { link }
  }
end

data = {
   :table1 => linkdata
}

tmpl.prettyprint = true
tmpl.expand(File.open("index.html", "w"), data)
