require.js doT plugin

This plugins loads dot-templates with require-text during development, and has the capabilities to build dependency free optimized versions with r.js

Usage

Create your template: persons.dot

<ul>
{{~ it.persons :person }}
  <li>
    <h2>{{= person.name }}</h2>
    <h3>{{= person.age }}</h3>
  </li>
{{~}}
</ul>

Use it:

define(['doT!persons'], function(tmpl) {
  var data = {
    persons: [
      { name: 'foo', age: 30 },
      { name: 'bar', age: 53 }
    ]
  };

  var html = tmpl(data);
});

Installation & Dependencies

Install with bower to get them all. You can also manually download doT.js or clone this repository and get the dependencies in whatever way you see fit.

bower install requirejs-doT

In your paths setup the mappings to the dependencies (change to fit your setup).

require.config({
  paths: {
    doTCompiler:  'components/doT/doT',
    text:         'components/requirejs-text/text',
    doT:          'components/requirejs-dot/doT'
  }
});

Config

templateSettings are passed into doT.templateSettings.

require.config({
  doT: {
    ext: '.dot', // extension of the templates, defaults to .dot
    templateSettings: {
      evaluate:    /\{\{([\s\S]+?)\}\}/g,
      interpolate: /\{\{=([\s\S]+?)\}\}/g,
      encode:      /\{\{!([\s\S]+?)\}\}/g,
      use:         /\{\{#([\s\S]+?)\}\}/g,
      define:      /\{\{##\s*([\w\.$]+)\s*(\:|=)([\s\S]+?)#\}\}/g,
      conditional: /\{\{\?(\?)?\s*([\s\S]*?)\s*\}\}/g,
      iterate:     /\{\{~\s*(?:\}\}|([\s\S]+?)\s*\:\s*([\w$]+)\s*(?:\:\s*([\w$]+))?\s*\}\})/g,
      varname: 'it',
      strip: true,
      append: true,
      selfcontained: false
    }
  }
});

Optimized

In a optimized build, the templates is defined as compiled doT function. So in optimized mode it doesn't really have dependencies at all, not even doT.

The optimized version of the persons.dot template above.

define("doT!persons",function(){return function(t){var n="<ul>",r=t.persons;if(r){var i,s=-1,o=r.length-1;while(s<o)i=r[s+=1],n+=" <li> <h2>"+i.name+"</h2> <h3>"+i.age+"</h3> </li>"}return n+="</ul>",n}})

If your application doesn't use require-text or doT somewhere else, you can go ahead and stub them from the build by using stubModules in your build.

stubModules: ['doTCompiler', 'text', 'doT']

Pitfalls

  • Remember to make sure your webserver can serve .dot-files during development (Or whatever extension you choose).
  • Optimizing isn't tested for Rhino yet...
