description

erb interprets a Ruby code embedded text file. For example, erb enables you to embed a Ruby code to a HTML file. A Ruby block starts with ’<%’ and ends with ’%>’. erb replaces the block with its output. If ’<%’ is followed by ’=’, eRuby replaces the block with a value of the block. If ’<%’ is followed by ’#’, the block is ignored as a comment.
