Eta

A lightweight PHP templating engine designed for rapid prototypes and small-scale web applications.

The symbol for the Greek capital letter eta is H. Eta is often used in math as the symbol for efficiency.

This engine was designed for prototypes and small-scale web applications that need to be developed and deployed quickly with minimal setup. Since Eta does not use custom template tags, projects can be easily turned over to a more robust framework like Cake or Yii in the future.

Installation

• Copy this file into a directory of your choosing and add the require_once to the file that is using Eta.
• The default directory for Eta is ./, but may be changed via H::setHome().
• The default page template for Eta is ./base.view, but this may be changed via H::setBase().

Usage

Here is a simple hello world example:

// index.php require_once "H.php"; $who = "World"; echo H::render(null, [ "name" => $who ]);

```php
// base.view
Hello <?= $name ?>!

Example of a template include:

render(path, [model], [grounded])

Render a template without auto-responding.

Parameters

• {String} path - Path to the template or null to use the base template.
• {Array} [model] - Data to inject into the template.
• {Boolean} [grounded] - False to use a literal path and bypass the home directory.

Returns {String}
Throws {MissingTemplateException}

// The 'grounded' argument can bypass the home directory
$myView = H::render("../my/template.html", [], false);

setHome(path, [remember])

Set a new default views directory.

Paramters

• {String} path
• {Boolean} [remember] - True to retain this as the default directory for use with reset().

// Default is the same directory in which eta.php file is placed.
H::setHome("/path/to/my/templates/");

setBase(path)

Set a new default base page template.

Paramters

• {String} path - Complete path to new base template.

// Default is ./base.view
H::setBase("/path/to/myBase.html");
// Now H::render(null) will use a new base template!

reset()

Reset Eta back to default home directory.

// Use special templates directory temporarily.
H::setHome("../path/to/other/templates/");
H::render("some/newThing.tpl");
H::render("and/another/template.html");
// Now reset home back to default for rest of project!
H::reset();
