The content of the tag is evaluated as Ruby code and is expected to be a path pointing to a Ruby template file which is read, evaluated, and rendered. Same as <% + %> but file contents are simply rendered into the output. Treats the enclosed code as a block of Ruby code and (if necessary) appends a do keyword to the body of the tag.
As with Unix shells, Ruby also allows for the delimiting identifier not to start on the first column of a line, if the start of the here document is marked with the slightly different starter <<-. Besides, Ruby treats here documents as a double-quoted string, and as such, it is possible to use the #{} construct to interpolate code. The ...
The syntax of the Ruby programming language is broadly similar to that of Perl and Python.Class and method definitions are signaled by keywords, whereas code blocks can be defined by either keywords or braces.
Ruby is an interpreted, high-level, general-purpose programming language. It was designed with an emphasis on programming productivity and simplicity. In Ruby, everything is an object, including primitive data types. It was developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan.
Flow diagram. In computing, serialization (or serialisation, also referred to as pickling in Python) is the process of translating a data structure or object state into a format that can be stored (e.g. files in secondary storage devices, data buffers in primary storage devices) or transmitted (e.g. data streams over computer networks) and reconstructed later (possibly in a different computer ...

In these languages, including the line __DATA__ (Perl) or __END__ (Ruby, old Perl) marks the end of the code segment and the start of the data segment. Only the contents prior to this line are executed, and the contents of the source file after this line are available as a file object: PACKAGE::DATA in Perl (e.g., main::DATA) and DATA in Ruby.
