Hello everyone,
I have a feature request here that comes from an internal struggle here
between view helpers, decorator patterns and ERB in general. A problem that
occurs from time to time is how to build HTML tags with different settings
depending on the some states. Here's an example of what I mean.
<% for @posts.each do |post|%>
<%= content_tag :li, post.title, class: "post #{post.id == 3 ? 'selected'
: ''}" %>
<% end %>
With builtin' methods, there's many way to build this kind of HTML tag. And
I'm sure people here knows a few of them. However, none seem to really make
it easy to build them. So I decided to take a stab at it this weekend and
came up with this solution.
<% for @posts.each do |post|%>
<%= content_tag :li, class: %w(post) do |li| %>
<% if post.id == 3 %>
<% li.css << 'selected' %>
<% end %>
post.title
<% end %>
<% end %>
All attributes can be either set inline (as previously possible) or through
a tag object that is available inside the block. Now, since this might not
be really easy to figure out how useful this could be, I created a helper
that overrides content_tag() and saved it as a gist for you to test out
locally. It's very possible that there's a few bugs as it's the very first
version.

Would this be something RoR:Core would be interested in merging into Rails?
