April1

Note:

1. Still in early development stage. Things may change.
2. XML and HTML output was removed in 0.3.1 – moved to april1-html.

April1 is a general-purpose, extensible template engine for the Node.js platform.

Main characteristics:

• Not coupled to any syntax. Templates are defined in plain JS. The extremely simple data structures can be (de)serialized by other packages.
• Separate components. Designed for easy overriding without breaking other parts, thanks to a well-defined set of constraints.

This is the core module. It provides basic functionality for more specialized modules.

Simple example:

var A = require ('april1');
var template = A.template (
	'Hello, ',
	A.insert ('who'),
	'.',
	A.list (
		'then',
		' ',
		A.insert ('item'),
		'.'
	)
);

The above code creates a reusable template.

Values are supplied afterwards:

var values = {
	who: 'World',
	then: [
		{ item: 1 },
		{ item: 2 },
		{ item: 3 }
	]
};

Now, the function call A.string (template, values) would by default return this string:

Hello, World. 1. 2. 3.

By default.

unit tests

The test folder contains a test script. It is rudimentary, but has good coverage.
