Build Status

It's like a tiny-templater but with a little dash of logic.

usage

var language = require('medium-templater')

var template_string
  , template
  , compile

template_string =
    '<ul>' +
    '{% for item in items %}' +
    '<li>{% if item.okay %}okay{% else %}not okay{% endif %}</li>' +
    '{% endfor %}' +
    '</ul>' +
    '{{ message }}'

compile = language()

template = compile(template_string)

var result = template({
    items: [{okay: true}, {okay: false}]
  , message: 'hello world'
})

console.log(result) // <ul><li>okay</li><li>not okay</li></ul>hello world

extending

Though you get if and for for free, you can also provide your own tags (or override the defaults if you don't like how they work!) like so:

index.js

var language = require('medium-templater')
  , reverse = require('./lib/reverse')

language({
    reverse: reverse
})

./lib/reverse.js

module.exports = reverse

function reverse(parser, tag_options) {
  var contents = ''

  parser.parse({'endreverse': end_reverse})

  return function(context) {
    // context is what is passed to the template, irrelevant in this example.
    return contents().split('').reverse().join('')
  }

  function end_reverse(tpl) {
    contents = tpl
  }
}

now you can:

{% reverse %}
!sredner etalpmet eht nehw thgir eb lliw txet siht
{% endreverse %}

further options

Specifying reversed at the end of a for statement (ie for item in items reversed) will parse the items in reverse. Specifying an {% empty %} tag after the {% for ... %} will return that chunk in the event of no items.
