haskell haskell@gentoo.org Shakespeare is a template family for type-safe, efficient templates with simple variable interpolation . Shakespeare templates can be used inline with a quasi-quoter or in an external file. Shakespeare interpolates variables according to the type being inserted. In this case, the variable type needs a ToJavascript instance. There is also shakespeare-coffeescript for coffeescript templates. Coffescript is a language that compiles down to javascript. It expects a coffeescript compiler in your path, and variable should be a ToCoffee instance. Please see http://docs.yesodweb.com/book/templates for a more thorough description and examples shakespeare-js was originally called julius, and shakespeare originated from the hamlet template package. Test coffee. Test export. Test roy.
