#
# = ERB -- Ruby Templating
#
# == Introduction
#
# ERB provides an easy to use but powerful templating system for Ruby. Using
# ERB, actual Ruby code can be added to any plain text document for the
# purposes of generating document information details and/or flow control.
#
# A very simple example is this:
#
# require 'erb'
#
# x = 42
# template = ERB.new <<-EOF
# The value of x is: <%= x %>
# EOF
# puts template.result(binding)
#
# Prints: The value of x is: 42
#
# More complex examples are given below.
#
#
# == Recognized Tags
#
# ERB recognizes certain tags in the provided template and converts them based
# on the rules below:
#
# <% Ruby code -- inline with output %>
# <%= Ruby expression -- replace with result %>
# <%# comment -- ignored -- useful in testing %> (`<% #` doesn't work. Don't use Ruby comments.)
# % a line of Ruby code -- treated as <% line %> (optional -- see ERB.new)
# %% replaced with % if first thing on a line and % processing is used
# <%% or %%> -- replace with <% or %> respectively
#
# All other text is passed through ERB filtering unchanged.
#
#
# == Options
#
# There are several settings you can change when you use ERB:
# * the nature of the tags that are recognized;
# * the binding used to resolve local variables in the template.
#
# See the ERB.new and ERB#result methods for more detail.
#
# == Character encodings
#
# ERB (or Ruby code generated by ERB) returns a string in the same
# character encoding as the input string. When the input string has
# a magic comment, however, it returns a string in the encoding specified
# by the magic comment.
#
# # -*- coding: utf-8 -*-
# require 'erb'
#
# template = ERB.new <<EOF
# <%#-*- coding: Big5 -*-%>
# \_\_ENCODING\_\_ is <%= \_\_ENCODING\_\_ %>.
# EOF
# puts template.result
#
# Prints: \_\_ENCODING\_\_ is Big5.
#
#
# == Examples
#
# === Plain Text
#
# ERB is useful for any generic templating situation. Note that in this example, we use the
# convenient "% at start of line" tag, and we quote the template literally with
# <tt>%q{...}</tt> to avoid trouble with the backslash.
#
# require "erb"
#
# # Create template.
# template = %q{

#
# === Ruby in HTML
#
# ERB is often used in <tt>.rhtml</tt> files (HTML with embedded Ruby). Notice the need in
# this example to provide a special binding when the template is run, so that the instance
# variables in the Product object can be resolved.
#
# require "erb"
#
# # Build template data class.
# class Product
# def initialize( code, name, desc, cost )
# @code = code
# @name = name
# @desc = desc
# @cost = cost
#
# @features = [ ]
# end
#
# def add_feature( feature )
# @features << feature
# end
#
# # Support templating of member data.
# def get_binding
# binding
# end
#
# # ...
# end
#
# # Create template.
# template = %{
# <html>
# <head><title>Ruby Toys -- <%= @name %></title></head>
# <body>
#
# <h1><%= @name %> (<%= @code %>)</h1>
# <%= @desc %>
#
# <ul>
# <% @features.each do |f| %>
# <li><%= f %></li>
# <% end %>
# </ul>
#
# 
# <% if @cost < 10 %>
# Only <%= @cost %>!!!
# <% else %>
# Call for a price, today!
# <% end %>
# 
#
# </body>
# </html>
# }.gsub(/^ /, '')
#
# rhtml = ERB.new(template)
#
# # Set up template data.
# toy = Product.new( "TZ-1002",
# "Rubysapien",
# "Geek's Best Friend! Responds to Ruby commands...",
# 999.95 )
# toy.add_feature("Listens for verbal commands in the Ruby language!")
# toy.add_feature("Ignores Perl, Java, and all C variants.")
# toy.add_feature("Karate-Chop Action!!!")
# toy.add_feature("Matz signature on left leg.")
# toy.add_feature("Gem studded eyes... Rubies, of course!")
#
# # Produce result.
# rhtml.run(toy.get_binding)
#
# Generates (some blank lines removed):
#
# <html>
# <head><title>Ruby Toys -- Rubysapien</title></head>
# <body>
#
# <h1>Rubysapien (TZ-1002)</h1>
# Geek's Best Friend! Responds to Ruby commands...
#
# <ul>
# <li>Listens for verbal commands in the Ruby language!</li>
# <li>Ignores Perl, Java, and all C variants.</li>

# <li>Gem studded eyes... Rubies, of course!</li>
# </ul>
#
# 
# Call for a price, today!
# 
#
# </body>
# </html>
#
#
# == Notes
#
# There are a variety of templating solutions available in various Ruby projects.
# For example, RDoc, distributed with Ruby, uses its own template engine, which
# can be reused elsewhere.
#
# Other popular engines could be found in the corresponding
# {Category}[https://www.ruby-toolbox.com/categories/template_engines] of
# The Ruby Toolbox.

# ERB::Compiler
class ERB
 # = ERB::Compiler
 #
 # Compiles ERB templates into Ruby code; the compiled code produces the
 # template result when evaluated. ERB::Compiler provides hooks to define how
 # generated output is handled.
 #
 # Internally ERB does something like this to generate the code returned by
 # ERB#src:
 #
 # compiler = ERB::Compiler.new('<>')
 # compiler.pre_cmd = ["_erbout=+''"]
 # compiler.put_cmd = "_erbout.<<"
 # compiler.insert_cmd = "_erbout.<<"
 # compiler.post_cmd = ["_erbout"]
 #
 # code, enc = compiler.compile("Got <%= obj %>!\n")
 # puts code
 #
 # Generates:
 #
 # #coding:UTF-8
 # _erbout=+''; _erbout.<< "Got ".freeze; _erbout.<<(( obj ).to_s); _erbout.<< "!\n".freeze; _erbout
 #
 # By default the output is sent to the print method. For example:
 #
 # compiler = ERB::Compiler.new('<>')
 # code, enc = compiler.compile("Got <%= obj %>!\n")
 # puts code
 #
 # Generates:
 #
 # #coding:UTF-8
 # print "Got ".freeze; print(( obj ).to_s); print "!\n".freeze
 #
 # == Evaluation
 #
 # The compiled code can be used in any context where the names in the code
 # correctly resolve. Using the last example, each of these print 'Got It!'
 #
 # Evaluate using a variable:
 #
 # obj = 'It'
 # eval code
 #
 # Evaluate using an input:
 #
 # mod = Module.new
 # mod.module_eval %{
 # def get(obj)
 # #{code}
 # end
 # }
 # extend mod
 # get('It')
 #
 # Evaluate using an accessor:
 #
 # klass = Class.new Object
 # klass.class_eval %{
 # attr_accessor :obj
 # def initialize(obj)
 # @obj = obj
 # end
 # def get_it
 # #{code}
 # end
 # }
 # klass.new('It').get_it
 #

# ERB
class ERB
 #
 # Constructs a new ERB object with the template specified in _str_.
 #
 # An ERB object works by building a chunk of Ruby code that will output
 # the completed template when run.
 #
 # If _trim_mode_ is passed a String containing one or more of the following
 # modifiers, ERB will adjust its code generation as listed:
 #
 # % enables Ruby code processing for lines beginning with %
 # <> omit newline for lines starting with <% and ending in %>
 # > omit newline for lines ending in %>
 # - omit blank lines ending in -%>
 #
 # _eoutvar_ can be used to set the name of the variable ERB will build up
 # its output in. This is useful when you need to run multiple ERB
 # templates through the same binding and/or when you want to control where
 # output ends up. Pass the name of the variable to be used inside a String.
 #
 # === Example
 #
 # require "erb"
 #
 # # build data class
 # class Listings
 # PRODUCT = { :name => "Chicken Fried Steak",
 # :desc => "A well messages pattie, breaded and fried.",
 # :cost => 9.95 }
 #
 # attr_reader :product, :price
 #
 # def initialize( product = "", price = "" )
 # @product = product
 # @price = price
 # end
 #
 # def build
 # b = binding
 # # create and run templates, filling member data variables
 # ERB.new(<<-'END_PRODUCT'.gsub(/^\s+/, ""), trim_mode: "", eoutvar: "@product").result b
 # <%= PRODUCT[:name] %>
 # <%= PRODUCT[:desc] %>
 # END_PRODUCT
 # ERB.new(<<-'END_PRICE'.gsub(/^\s+/, ""), trim_mode: "", eoutvar: "@price").result b
 # <%= PRODUCT[:name] %> -- <%= PRODUCT[:cost] %>
 # <%= PRODUCT[:desc] %>
 # END_PRICE
 # end
 # end
 #
 # # setup template data
 # listings = Listings.new
 # listings.build
 #
 # puts listings.product + "\n" + listings.price

 #
 # Chicken Fried Steak
 # A well messages pattie, breaded and fried.
 #
 # Chicken Fried Steak -- 9.95
