# Embedded Crystal (ECR) is a template language for embedding Crystal code into other text,
# that includes but is not limited to HTML. The template is read and transformed
# at compile time and then embedded into the binary.
#
# There are `<%= %>` and `<% %>` syntax. The former will render returned values.
# The latter will not, but instead serve to control the structure as we do in Crystal.
#
# Using a dash inside `<...>` either eliminates previous indentation or removes the next newline:
#
# * `<%- ... %>`: removes previous indentation
# * `<% ... -%>`: removes next newline
# * `<%-= ... %>`: removes previous indentation
# * `<%= ... -%>`: removes next newline
#
# Quick Example:
#
#     require "ecr"
#
#     class Greeting
#       def initialize(@name : String)
#       end
#
#       ECR.def_to_s "greeting.ecr"
#     end
#
#     # greeting.ecr
#     Greeting, <%= @name %>!
#
#     Greeting.new("John").to_s
#     #=> Greeting, John!
#
# Using logical statements:
#
#     # greeting.ecr
#     <%- if @name -%>
#     Greeting, <%= @name %>!
#     <%- else -%>
#     Greeting!
#     <%- end -%>
#
#     Greeting.new(nil).to_s
#     #=> Greeting!
#
# Using loops:
#
#     require "ecr"
#
#     class Greeting
#       @names : Array(String)
#
#       def initialize(*names)
#        @names = names.to_a
#       end
#
#       ECR.def_to_s "greeting.ecr"
#     end
#
#     # greeting.ecr
#     <%- @names.each do |name| -%>
#     Hi, <%= name %>!
#     <%- end -%>
#
#     Greeting.new("John", "Zoe", "Ben").to_s
#     #=> Hi, John!
#     #=> Hi, Zoe!
#     #=> Hi, Ben!
#
# Likewise, other Crystal logic can be implemented in ECR text.
