eruby ā€” Embedded Ruby Language


eruby [options] [inputfile]


eruby interprets a Ruby code embedded text file. For example, eruby enables you to embed a Ruby code to a HTML file.

A Ruby block starts with `<%' and ends with `%>'. eRuby 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.
