Eta

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

composer require cobbdb/eta

---

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
]);

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

Example of a template include:

<div id="myWidget">
    <?= H::render("neat/widget.html") ?>
</div>

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();
