EJS (Embedded JavaScript) template compiler for Ruby

EJS templates embed JavaScript code inside <% ... %> tags, much like ERB. This library is a port of Underscore.js's _.template function to Ruby, and strives to maintain the same syntax and semantics.

Pass an EJS template to EJS.compile to generate a JavaScript function:

EJS.compile("Hello <%= name %>")
# => "function(obj){...}"

Invoke the function in a JavaScript environment to produce a string value. You can pass an optional object specifying local variables for template evaluation.

The EJS tag syntax is as follows:

• Unescaped buffering with <%- code %>
• Escapes html by default with <%= code %>
• Unbuffered code for conditionals etc <% code %>

If you have the ExecJS library and a suitable JavaScript runtime installed, you can pass a template and an optional hash of local variables to EJS.evaluate:

EJS.evaluate("Hello <%= name %>", :name => "world")
# => "Hello world"
