combine: node implementation

A template engine that hopefully works the way you'd expect :3.

Getting started

To install combine, you can clone this repository to your node_modules folder or use the fantastic NPM:

npm install node-combine

Then simply require it in your projects to start using

var combine = require('node-combine');

Basic usage

var tmpl = combine('{{test}}', { test: 'lol' });
tmpl.render(); // LOL 




combine works by parsing your template into a stack and rendering data.

Replacing template variables####

var template = '{{lol}}';
var context = { lol: 'test' };
var tmpl = combine(template, context);
var output = tmpl.render();
/// output == 'test' 

Using filters on variables####

var template = '{{test|reverse}}';
var context = { lol: 'test' };
var tmpl = combine(template, context);
tmpl.filters.add('reverse', function(val) {
  return val.split('').reverse().join('');
var output = tmpl.render();
/// output == 'tset' 


Instead of being logic-less, combine doesn't make any assumptions and allows you to do things like if/elsif/else with simple conditionals, such as if something = somethingElse or if not something. You may only test against strings, all data types will be coerced with toString().

var template = '{%if not test%}why not?{%endeach%}';
var context = { test: false };
var tmpl = combine(template, context);
var output = tmpl.render();
/// output == 'why not?' 

or a more complicated example...

var template = '{%if test = hello%}goodbye!{%else%}hello!{%endeach%}';
var context = { test: 'hello' };
var tmpl = combine(template, context);
var output = tmpl.render();
/// output == 'goodbye!' 

Iterating arrays####

Will not work on array-like objects, such as arguments or NodeList, coerce with;

var template = '{%each test%}{{.}} {%endeach%}';
var context = { lol: [1,2,3,4] };
var tmpl = combine(template, context);
var output = tmpl.render();
/// output == '1 2 3 4 ' 

Iterating objects####

var template = '{%each test key,val%}the {{key}} is {{val}}{%endeach%}';
var context = {
  lol: {
    hello: 'lol'
var tmpl = combine(template, context);
var output = tmpl.render();
/// output == 'the hello is lol' 

Running unit tests

Run the follow command to fetch the Node.js dependencies.
