Text.Roy

A Shakespearean module for Roy, introducing type-safe, compile-time variable and url interpolation. It is exactly the same as Text.Julius, except that the template is first compiled to Javascript with the system tool roy.

To use this module, roy must be installed on your system.

#{...} is the Shakespearean standard for variable interpolation, but CoffeeScript already uses that sequence for string interpolation. Therefore, it seems more future-proof to use %{...} for interpolation

Integration with Roy is a bit rough right now. You can only perorm a shakespeare insertion inside a Roy string. This should work well for urls and strings. Otherwise you should stick your Haskell into Julius as a window variable, and then retrieve it in your Roy code.

Functions

Template-Reading Functions

These QuasiQuoter and Template Haskell methods return values of type JavascriptUrl url. See the Yesod book for details.

roy :: QuasiQuoter

Read inline, quasiquoted Roy.

royFile :: FilePath -> Q Exp

Read in a Roy template file. This function reads the file once, at compile time.

royFileReload :: FilePath -> Q Exp

Read in a Roy template file. This impure function uses unsafePerformIO to re-read the file on every call, allowing for rapid iteration.
