How do I execute ruby template files (ERB) without a web server from command line?

Question

I need ERB (Ruby\'s templating system) for templating of non-HTML files.
(Instead, I want to use it for source files such as .java, .cs, ...)

Answer 1

Write a ruby script that does it. The API documentation is here: http://www.ruby-doc.org/stdlib/libdoc/erb/rdoc/

For example:

template = ERB.new File.read("path/to/template.erb"), nil, "%"
template.result(binding)

(Where binding is a binding with the @vars that the template needs.)
