Overview

The Generator is in charge of taking an array of Mustache tokens, usually assembled by the Parser, and generating an interpolatable Ruby string. This string is considered the “compiled” template because at that point we're relying on Ruby to do the parsing and run our code.

For example, let's take this template:

Hi {{thing}}!

If we run this through the Parser we'll get these tokens:

[:multi,
  [:static, "Hi "],
  [:mustache, :etag, "thing"],
  [:static, "!\n"]]

Now let's hand that to the Generator:

>> puts Mustache::Generator.new.compile(tokens) “Hi #.to_s)!n”

You can see the generated Ruby string for any template with the mustache(1) command line tool:

$ mustache --compile test.mustache
"Hi #{CGI.escapeHTML(ctx[:thing].to_s)}!\n"
