Mustache for Racket

A Racket implementation of Mustache.

Installation

$ raco pkg install "git://github.com/adolfopa/racket-mustache.git?path=mustache"

Quick Introduction

Lets create a simple Mustache template that outputs a single value. First, create a file named simple.ms (the .ms extension is not required; you can use whatever you want).

#lang mustache
Hey! this is my {{adjective}} Mustache template.

Note that templates must have #lang mustache as the first thing in the file for Racket to detect it as a Mustache template.

Templates are compiled into regular racket modules. To invoke the template from another module, simply require it and call the render function. Type this into a simple-test.rkt file in the same directory where simple.ms is:

#lang racket

(require "simple.ms") ; imports the `render` function

(module+ main
  (render (hash "adjective" "first") (current-output-port)))

The render function has the following signature:

(: render ((Dict String Any) Port -> Void))

where the first argument is a dict mapping names (strings) to values (any racket value); the second argument is the port where the template will write its output.

If you execute the simple-test.rkt script you should see something like:

$ racket simple-test.rkt
Hey! this is my first Mustache template.

And that's it!
