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

If you can switch ERB to Erubis, your problem solving is as simple as:

require 'erubis'
template = File.read("sample_file.erb")
template = Erubis::Eruby.new(template)
template.result(:your_variable => "sample")
