Examples

See examples

Build examples:

node ./bin/temple examples/*temple # Dump on stdout
node ./bin/temple examples/*temple > templates.js # Dump into templates.js

Use

Load scripts [temple_utils.js, templates.js]

Or cat templates.js temple_utils.js > res.js and paste it into chrome console

console.log(JSON.stringify(window.templates_pool.info())); # pool is empty
var t = window.templates_pool.get("ss"); # Load empty ss template
console.log(JSON.stringify(window.templates_pool.info())); # pool has one busy ss item
console.log(t[0]); # Look as dom
t[1].A("FiRsT");
console.log(t[0]);
t[1].B([{C: 1, E: "Yahhhoo!"},{C: 2, E: "MMMM",D: [1,1,1,9]}]);
console.log(JSON.stringify(window.templates_pool.info())); # more busy templates
window.templates_pool.build_cache({"ss": 100}); # build 100 elements cache for ss template
console.log(JSON.stringify(window.templates_pool.info())); # fresh new 100 ss items ready for action
console.log(t[0]);

Using instruction for browser env

1. Write temple file

For example, your template file my_template.temple looks like:

<div id="{{id}}">
  {{name}}
</div>

2. Compile

Build temple functions from template:

node path/to/temple/bin/temple my_template.temple > templates.js

3. Include template

Also don't forget include temple_utils.jsto your page, head section must look like:

<script src="temple_utils.js"></script>
<script src="templates.js"></script>

After that you'll have templates variable with all your templates and temple manipulations methods. Templates named by filename, for example you get templates.get('my_template').

4. Fill template by data

For example, you want render simple information:

data = {
  "id": 1,
  "name": "John"
}

Don't forget that json must be valid, you can try validator first. And finnaly pass data to your template:

myTemplate = templates.get('my_template', data);

or

pool = templates.get('my_template')[1];
myTemplate = pool.update(data);

Variable myTemplate its array with [0] DOM template and [1] temple methods for template.

5. Append template to DOM

div = document.getElementById('place-for-append')
div.appendChild(myTemplate[0])

Syntax

Temple templates are valid XML-tree:

<div id="{{id}}">
  {{name}}
</div>

Loops:

You can use forall instruction for render each item of array:

<ul>
  <forall key="items">
    <li>{{value}}</li>
  </forall>
</ul>

Conditional statements:

And use if for simple conditions:

<div>
  <if key="plane">
    Flight number: {{airline}} {{number}}
  </if>
  <if key="train">
    Train number: {{number}}
  </if>
</div>

Partial templates:

Use include to include partial template:

<include name="foo" key="value"/>

where foo is template name, and value is data for rendering;

Methods

.info()

.get(template_name)

myTemplate = templates.get('my_template');

.get(template_name, data)

myTemplate = templates.get('my_template', {data: data});

.update(data)

.build_cache({template_name: num_of_copy})

templates.info().free
templates.build_cache({‘my_template’: 1000})
templates.info().free

.remove()

.root()

Return DOM element

.child_template_name()

Temple provide setters for child template, for template my_template

<ul>
  <forall key="items">
    <li>{{data}}</li>
  </forall>
</ul>

You'll have

myTemplate = templates.get('my_template')[1]
myTemplate.items([{"data": "some data"}, {"data": "some data2"}])
