Armadillo
A small library for Django-like template inheritance adapted for ERB.
Usage
To render an Armadillo template you need to call the Armadillo.render method.
This method accepts any of the following options:
-
:scope- Any object you want to bound to the template scope. -
:base_path- The path of the directory for which the templates are going to be searched on.
Note: A .erb extension is assumed for every file and should not be part of
the filename given as the template filename.
Armadillo.render("myview.html", { :items => [1, 2, 3] }, {
:base_path => File.join(Dir.pwd, "views"),
:scope => self
})<!-- views/myview.html.erb -->
<% extends("base.html") %>
<% vlock(:title) do %>
<%= current_user.name %>
<% end %>
<% vlock(:body) do %>
<ul>
<% items.each do |item| %>
<li><%= item %></li>
<% end %>
</ul>
<% end %>
<!-- views/base.html.erb -->
<!DOCTYPE>
<html>
<title><% vlock(:title) %> - MyApp</title>
<body>
<% vlock(:body) %>
</body>
</html>Usage example using Cuba
module View
def render_view(template_name, locals = {})
content = Armadillo.render(template_name, locals, {
:base_path => File.join(APP_PATH, "views"),
:scope => self,
:escape_html => true
})
res.write(content)
halt(res.finish)
end
end
on get, root do
render_view("main/index.html", {
:items => [1, 2, 3]
})
end
