List of messages

html # outer template ot = TemplateText.new <<-html html # build msglist data = Hash.new{|h,k| h[k] = []} messages = %w(one two three) messages.inject(data){|data, msg| data[:list] << {:msg => msg}; data} msglist = it.expand('', data) # build main page data = Hash.new data[:msglist] = noescape{ msglist } ot.expand(STDOUT, data) ~/eg/ruby > ruby amrita0.rb

List of messages

or: ~/eg/ruby > cat amrita1.rb require 'amrita' require 'amrita/parts' include Amrita module View class MsgList TEMPLATE = TemplateText.new <<-html

List of messages

html attr :list def initialize; @list = []; end def << msg; @list << {:msg => msg}; self; end end MsgList::TEMPLATE.install_parts_to self end msglist = View::MsgList.new msglist << 'one' << 'two' << 'three' t = TemplateText.new <<-html html t.expand STDOUT, {:msglist => msglist} ~/eg/ruby > ruby amrita1.rb
