Support for PHP 7.2 is here!

For all who doesn't know about new type of versions of Nette Framewor 2.4, there is no planed 2.4.x version. All packages have their maintenance version, but Framework doesn’t have. There is build from (2017–08–29) with release notes, that is full compatible with incomming PHP version 7.2

We spent summer together at an extraordinary meeting Nette Camp and two excursions to Czech breweries. Definitely follow up the events next year. It's an interesting way to meet in an offline world. In September, the 90th anniversary Last Saturday is waiting for us.

PhpStorm and code completion for $this->template

by David Grudl about a month ago in Nette

How to get rid of PhpStorm alerts on “undefined fields” and activate the code completion for $this->template in presenters?

So how to change this view with the underlined abc and the empty pop-up window:

Into this?

Simply. Just add the following annotation to the presenter (for example to BasePresenter):

 * @property-read \Nette\Bridges\ApplicationLatte\Template|\stdClass $template
abstract class BasePresenter extends Nette\Application\UI\Presenter

Note: In the latest versions of Nette, this annotation will be directly in the code.

Template class

The stdClass class in the annotation is a workaround for PhpStorm, which otherwise treats all variables as undefined. However, it is more interesting to create a class with a real list of the variables that the template uses, including their types. It may look like this:

class ArticleTemplate
    /** @var string */
    public $lang;

    /** @var int */
    public $page;

    /** @var string[] */
    public $menu;

    /** @var Model\Page */
    public $article;

And then put it in the annotation of a specific presenter instead of stdClass:

 * @property-read ArticleTemplate|\Nette\Bridges\ApplicationLatte\Template $template
final class ArticlePresenter extends Nette\Application\UI\Presenter

From now on, the message is perfect:

We still have to solve the suggestion in the template. So far, Latte plugin can't do it, but once it can, it could use the same template class. For example, there could be a new macro {template App\Presenters\ArticleTemplate} that will pass the template class name.

New Nette 2.4 is out

After a summer break, here comes a whole heap of news and info about what has been going on and what is in the picture. The hottest piece of news is the new version of Nette Framework 2.4. A complex overview of changes made to the framework, including all novelties related to versioning, can be found on the release webpage:…2-4-released. In short, in the future only respective packages will be versioned (such as the release described here:…4-2016-07-31). Other big changes that should be mentioned is Nette/Object replacement with traits, see David's talk from Hradec Králové:… and the fact the “guts” of Latte, a template system, have been rewritten (a video from Plzeň will be published on YouTube soon). Here is also a post bringing attention to what you need to be careful about when migrating:…nette-2-4-rc. If you're still unsure whether you should use the latest version of Nette Framework or not, why don't you read a short post from the Slevomat boys about changin to 2.4:…122388672512, there are more and more companies following the example. In case you run on 2.4 too, tweet with hashtag #nettefw.

Nette Camp

A four-day event filled with Nette and beer took place in a quaint village in Czech Paradise and judging from the reactions, it was a hit. Speaking on behalf of organisers, we have learnt yet a lot and let's hope it will be for the benefit of future events. You can expect Nette Camp 2017 again in the last two weeks of August. As a surprise we migrated to a new portal: .

Following several meetings with Tomáš Votruba, the Czech Symfony community care-taker, we put our heads together and we are starting to build a framework non specific php community. More news to be expected on twitter @pehapkari. Follow us for what's hot in the czech php world. We started to broadcast a podcast too! :

In a Nutshell

Nextras & Kdyby

Compatible extensions releases go hand in hand with the release of new Nette Framework version. Most packages are compatible with Nette 2.4 already, if sometimes in @dev versions for now. We are still waiting for some stable releases.


Petr Knap from Netpromotion released a simple PHP profiler with a Tracy extension:…ion/profiler

Nette and Webpack

Jirka Pudil wrote an article on how to interlink these two platforms in an easy way:…with-webpack

In Conclusion

If you have ideas how to improve our next edition, please let me know. Have I forgotten something? Make sure to email me and we will include it in the next edition. We are still looking for partners who wish to address the growing community interested in our news.

Nette 2.4 is coming closer

At the last PoSobota meetup, David Grudl introduced the news waiting for us in the version 2.4 which should become the LTS in Nette version 2. There are big plans with Nette version 3, especially regarding PHP 7, therefore the version 2.4 should most likely be the version for all Nette 2.x projects to stick to for good, thus the prolonged support. As of today, the minimal support of each .x version is 2 years, prolonged by at least a year in the LTS version.

Nette Camp

Summer is coming! (pun intended) and the planned outing in the open is coming with it. You can pre-register at Together with Tomas Jacik, we are preparing many new things and we will try to overcome the obstacles exposed by last year’s 0th Camp. The date is 25 – 28 August 2016 and we are moving the venue to Český ráj.



Dan Kadera is actively working on Nittro, a JavaScript framework for Nette Framework. Among new components, there is: Paginator, AutoConfirm or Dropzone. Make sure to follow @nittrojs for upcoming demos.

VS Code

If you are coding in VS Code, you will surely be pleased with syntax support for Latte and NEON.…


A new version of the utility Viktor was released. The utility checks whether you have the latest version of libraries installed with composer.

Worth reading…

Martin Zlamal published an article about replacing RobotLoader with PSR-4 in a new Nette application.…der-aplikace

And not only that. He also wrote an article describing how the “magical” mapping of presenters works.…g-presenteru

We Are Expanding

Our Czech mailing list community already counts more than 600 subscribers. It is a shame that we are not able to gauge the exact count of newcomers who decided to read this actual post. But I believe that this number is going to rise at least as fast as the Czech, local one.

Nette Framework

A new patch version of Nette Framework has just released. It brings a few novelties that may be found at…3-9-released. I cannot leave out, at least, one of them – it is now possible to turn off the Tracy by Debugger::$showBar = FALSE; The last stable versions (2.3.9, 2.2.12 and even 2.1.12) are fully compatible with PHP 7 and, as a bonus, version 2.3.9 is able to get use of PHP 7 features as argument type hints and a return type of a generated factory.

But this is not the end yet. There has also been proposed Nette 2.4 release plan; the subsequent issue of this newsletter is going to contain some more info about it.

Tracy Built Upon AJAX

David Kadera is currently working on some changes that I would like to mention. The functionality of Tracy is going to be enhanced with support for AJAX (and likely CLI also) – the first dose of code and tests are already online. You can review a working prototype at…ree/ajax-bar.

PhpStorm Plugins

The popular PhpStorm plugins have been updated – David Matějka submitted their new versions during February. Especially autocomplete feature in the NEON plugin works pretty well. David has also recoded a core of Nette Framework plugin that is no longer causing occasional deadlocks. And this is not the end – a new version of Latte plugin has also been released, which (besides of ordinary and n: macros) fully supports HTML, Emmet, JavaScript and CSS development.

These plugins are accessible through the JetBrains Plugin Repository (Neon, Nette and Latte). You might also want to support us by starring our corresponding GitHub repositories. Neon ★, Nette ★, Latte ★


More and more people are coming to our informal discussing event, so as a consequence, we are expanding to even more locations during the next month. A new Facebook page is about to be set that is going to work as a hub of organizing these events at even more places – e.g. it will be possible to involve cities as Vienna or Berlin.


You can support our team by purchasing official Nette t-shirts from a recently launched online store. Also, when you are buying a t-shirt, don't forget to order some more Nette stickers; Unfortunately, out-of-Czech delivery is not currently supported. But anyway, in case of demand of any item, you can still contact me.


A reveal of NettePro is coming soon. David Matějka has already coded a ticket support app and David Grudl is finishing a registration tool and a dashboard containing info provided to our partners. Last, my work is to hire people for a support team (Nette Support Commando – will be adjusted ;-) ).

In a Nutshell


Milan is constantly updating a new addons portal which is about to lose its beta tag soon. Test it and leave a feedback.


A lifespan of this hangover tool is certainly heading to the end. A Newer version of Nette Framework will replace this object by Trait collection. You can already see it in production at Dibi and Texy projects.

Nextras ORM 2

Nextras community has released new major version of its new popular ORM newcomer. Change list may be accessed from here.

Nette Tester & PhpStorm

Jirka is currently working on a code integration, see the online repository.
