Spackle allows you to add code blocks and substitutions to any file.

Creating Templates


Substitution Notation: {{...}}

   Hello, my name is {{name}}.

Substitutions will be replaced based on the configuration of their Parser.

Code Blocks

Code Block Notation: {{> ... <}}

    echo "Hello, Word!";

Code blocks are always parsed last, this way you can use substitutions and other plugins within code blocks.

  foreach ({{likes}} as $likeable) {
    echo '<li>';
    echo $likeable;
    echo '</li>';


Plugin Notation: {{key ... <}}

You can create your own plugins to parse custom template keys.

See CodeBlockParser.php for an example of a plugin.

class MyPlugin extends \Spackle\Plugin
    // The key used to notate the beginning of this element.
    public $key = 'url';

    // Parse each element found matching this plugin.
    // {{url some/data <}} woud come out to https://localhost/some/data
    public function parse($data)
        return 'https://localhost/'.$data;

. . .

// Add on a global scope
\Spackle\Plugin::add(new MyPlugin());

// Add to a specific parser
$parser->addPlugin(new MyPlugin());

Parsing Templates

Once you've created a template, you can parse it in PHP. To parse the template you need to create an instance of \Spackle\TemplateParser. In the following example, we will use the \Spackle\FileParser class. It is a subclass of the TemplateParser, the only difference being that it loads the contents of a file in instead of using a string.

For this example, we will use the following Spackle Template stored in ./test.spackle.

<h4>Welcome to Spackle!</h4>

Spackle was created by <a href="{{github_url}}" target="_blank">{{name}}</a>.<br />

Some things that {{name}} likes are:<br />

    foreach ({{likes}} as $likeable) {
        echo '<li>';
        echo $likeable;
        echo '</li>';


<b>Bound: {{> echo $this->bound; <}}

Now, to parse it we will need to tell it what values to use.


include_once __DIR__.'/vendor/autoload.php';

use \Spackle\FileParser;

// The FileParser extends the TemplateParser
// and instead of cunstructing with a string
// is uses a file path.
$parser = new FileParser(
    // Template File Path

    // Optional Substitutions (add more with $parser->setSubstitution($key, $val))
        'github_url' => '',

// You can set substitutions easily using the setSubstitution
// member function of a TemplateParser.
$parser->setSubstitution('name', 'Nathan Fiscaletti');

// You can also bind the Parser to a specific object.
// Anytime you reference `$this` in your code blocks
// within the template, this bound object will be
// referenced.
$bindTest = (object)[
    'bound' => 'Yes, Bound.'

// You can use functions for substitutions.
// When the return value is an integer or
// a string, it will be directly substituted.
// Otherwise, the value will be used.
$parser->setSubstitution('likes', function() {
    return ['Coding', 'PHP', 'Trial by Combat'];

// The ->parse() function will parse the template
// and return the parsed value.
echo $parser->parse();

This should output something like this:

Welcome to Spackle!

Spackle was created by Nathan Fiscaletti.

Some things that Nathan Fiscaletti likes are:
    * Coding
    * PHP
    * Trial by Combat

Bound: Yes, Bound.

(You can find this example in ./example/

Why stop there?

You can use Spackle for any file type you want, since it's a glorified regex matcher.

For example, JavaScript:

console.log("Hello, {{name}}!");
