Turanct/Shack

A Stack middleware that will add a unique identifier (sha) to the application. It will set a custom header (X-Shack-Sha) containing the sha.

Example

<?php

$app = new Silex\Application();

$app->get('/', function() use ($app) {
    return 'Hello World';
});

$stack = new Stack\Builder();
$stack->push('Turanct\Shack', new Turanct\Shack\Git());
$app = $stack->resolve($app);

Usage

Just pass in the right Sha type as argument to the Turanct\Shack constructor (Git, RevisionFile, String), and Shack will take care of the rest.

Options:

• Turanct\Shack\Git will run a git command on your server, to retreive the current HEAD's sha
• Turanct\Shack\RevisionFile will use the contents of a given file as sha. This is particulary handy when using Capistrano, as there's a Capistrano task to create these files. You can just pass the revision file path as a constructor parameter.
• Turanct\Shack\String takes any string and uses that as the sha. This might be handy to use when you want to set the sha yourself, e.g. using ENV variables.

If you want to disable the html sha stamp on your html pages, just pass false to the Turanct\Shack constructor.
