module Roda::RodaPlugins::NamedTemplates

  1. lib/roda/plugins/named_templates.rb

The named_templates plugin allows you to specify templates by name, providing the template code to use for a given name:

plugin :named_templates

template :layout do
  "<html><body><%= yield %></body></html>"
end
template :index do
  "<p>Hello <%= @user %>!</p>"
end

route do |r|
  @user = 'You'
  render(:index)
end
# => "<html><body><p>Hello You!</p></body></html>"

You can provide options for the template, for example to change the engine that the template uses:

template :index, engine: :str do
  "<p>Hello #{@user}!</p>"
end

The block you use is reevaluted on every call, allowing you to easily include additional setup logic:

template :index do
  greeting = ['hello', 'hi', 'howdy'].sample
  @user.downcase!
  "<p>#{greating} <%= @user %>!</p>"
end

This plugin also works with the view_options plugin, as long as you prefix the template name with the view subdirectory:

template "main/index" do
  "<html><body><%= yield %></body></html>"
end

route do |r|
  set_view_subdir("main")
  @user = 'You'
  render(:index)
end
