Question

I need to create routes that include a colon to produce URLs like http://app.com/prjct:a9b5c. Obviously it’s currently simple to use a slash instead with the default routing.

$SLUG = array('slug' => '[-_A-Za-z0-9]+');
Router::connect('/prjct/:slug', array('controller' => 'projects', 'action' => 'show'), $SLUG);

But routes specifications use the colon character as a special indicator, which interferes with my naive attempt to replace the second slash above with another colon.

How do I use colons in this case for a route?

You can use named parameter as explained in CakePHP Cookbook. Write code below in your app/config/routes.php:

// Parse only the 'prjct' parameter if the current action is 'show' and the controller is 'projects'.
Router::connectNamed(array('prjct' => array('action' => 'show', 'controller' => 'projects')));

// Then set default route to controller 'projects' and action 'show
Router::connect('/', array('controller' => 'projects', 'action' => 'show'));

In your projects_controller.php :

function show(prjct = null) {
    // Check if prjct match the pattern
    $pattern = '[-_A-Za-z0-9]+';
    if(!preg_match($pattern, prjct)){
        // Redirect somewhere else
    }
    // Rest of your code here
}
