shakespeare-2.0.7: A toolkit for making compile-time interpolated templates

Text.Roy

Contents

Description

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.

If you interpolate variables, the template is first wrapped with a function containing javascript variables representing shakespeare variables, then compiled with roy, and then the value of the variables are applied to the function. This means that in production the template can be compiled once at compile time and there will be no dependency in your production system on roy.

Your code:

let b = 1
console.log(#{a} + b)

Final Result:

;(function(shakespeare_var_a){
  var b = 1;
  console.log(shakespeare_var_a + b);
})(#{a});

Synopsis

Functions

Template-Reading Functions

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

roy :: QuasiQuoter Source

Read inline, quasiquoted Roy.

royFile :: FilePath -> Q Exp Source

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

royFileReload :: FilePath -> Q Exp Source

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