ci-pug
ci-pug is a library for CodeIgniter to enable Pug Template Engine to render views with .pug or .jade extension.
- all files in the view folder ending with .pug or .jade can be rendered from the controllers, but you can still use any other files as views. So you're free to use Pug for all your views or just some of them.
- use the
'cache' => true
setting to render your views only once and save rendered files the cache folder, then serve cached file with no performance loss, views will be loaded as fast as the equivalent php views. You can also use'cache' => '/your/cutom/path
- ci-pug wait for you to load it. Only controllers with
use CiPug;
will load the wrapper, and until you call$this->settings()
or$this->view()
in the controller, the template engine will not be loaded.
Installation
You need PHP 5.4 or later to run ci-pug. If you use an earlier version of PHP we recommend you to upgrade. If you cannot, you can download the library version of ci-pug (available on PHP 5.3).
Open a terminal in the application folder in your CodeIgniter project, then enter:
composer require ci-pug/ci-pug
Be sure $config['composer_autoload'] = true;
in your
application/config/config.php file
How to use it?
application/controllers/Main.php
<?php
namespace App\Controllers;
class Home extends BaseController
{
use \CiPug;
public function index()
{
$this->view('myview');
}
}
application/views/myview.pug
doctype html
html(lang='en')
head
title My Pug View
body
h1 Hello World!
Pass variables
application/controllers/Main.php
<?php
namespace App\Controllers;
class Home extends BaseController
{
use \CiPug;
public function index()
{
$this->addVars([
'title' => 'My Pug View',
'authors' => [
'Luke',
'Leia',
'Lando'
]
]);
$this->view('myview');
}
}
or
<?php
namespace App\Controllers;
class Home extends BaseController
{
use \CiPug;
public function index()
{
$this->view('myview', [
'title' => 'My Pug View',
'authors' => [
'Luke',
'Leia',
'Lando'
]
]);
}
}
All variables from ->view()
or ->addVars()
are
merged and available in the view.
application/views/myview.pug
doctype html
html(lang='en')
head
title=title
body
ul
each author in authors
li=author
Keep rendered views in cache
We recommend you to do it in production to serve the views faster.
application/controllers/Main.php
<?php
namespace App\Controllers;
class Home extends BaseController
{
use \CiPug;
public function index()
{
$this->settings([
'cache' => true
]);
$this->view('myview');
}
}
Or you can use a custom storage folder:
$this->settings([
'cache' => '/tmp/my-cache-folder'
]);
If the folder does not exist, the library will try to create it.
Return the view instead of displaying it
$content = $this->view('foo', true);
echo str_replace('<hr>', '----------', $content);
// works also with vars
$content = $this->view('foo', [
'var1' => 1,
'var2' => 2
], true);
// and also with view auto-selection
$content = $this->view(true);
// see view auto-selection section below
Controller settings
This feature requires PHP 5.6 and allow you to specify settings for the whole controller.
<?php
namespace App\Controllers;
class Home extends BaseController
{
use \CiPug;
const SETTINGS = [
'cache' => true
// here, you can add any option
];
public foo()
{
$this->view('welcome/foo'); // will use the SETTINGS class constant
}
public bar()
{
$this
->settings([
'cache' => false// will override the SETTINGS class constant
])
->view('welcome/bar');
}
}
Tip: you can create and abstract controller with use CiPug;
and SETTINGS constant,
then extend this abstract class from several controllers.
View auto-selection
If you do not specify the view file, the most logic one with the given class and method will be taken:
abstract class BaseController extends Controller
{
use CiPug;
// ...
}
class Foo extends BaseController
{
public function index()
{
$this->view(); // load application/views/foo/index.pug
// or application/views/foo.pug if it does not exist
}
public function bar()
{
$this->view(); // load application/views/foo/bar.pug
// or application/views/foo/bar/index.pug if it does not exist
}
}
class Yep extends BaseController
{
public function index()
{
$this->view([
'some' => 'var'
]); // load application/views/yep/index.pug
// or application/views/yep.pug if it does not exist
}
public function nop()
{
$content = $this->view(true); // load application/views/yep/nop.pug
// or application/views/yep/nop/index.pug if it does not exist
}
public function dontKnow()
{
$this->view('yep/nop'); // load application/views/yep/nop.pug
// or application/views/yep/nop/index.pug if it does not exist
}
}
Custom views folder
If you do not store your .pug files in application/views,
use the view_path
setting:
$this->settings([
'view_path' => APPPATH . 'pug-templates'
]);
Disallow .jade
legacy file extension
If you use only up-to-date .pug
file extension, you can disallow the .jade
extension
to avoid unnecessary file existence checks:
class PugController extends BaseController
{
use CiPug;
public function __construct()
{
$this->disallowJadeFile();
}
}
