Leonid Mamchenkov:
Validating JSON against schema in PHP
Mar 13, 2017 @ 11:13:53

In this new post to his site Leonid Mamchenkov talks about validating JSON content sent to your application to ensure it matches a JSON schema definition.

GitHub was rather slow yesterday, which affected the speed of installing composer dependencies (since most of them are hosted on GitHub anyway). Staring at a slowly scrolling list of installed dependencies, I noticed something interesting.

Of course, I’ve heard of the seld/jsonlint before. It’s a port of zaach/jsonlint JavaScript tool to PHP, written by Jordi Boggiano, aka Seldaek, the genius who brought us composer dependency manager and packagist.org repository.

But JSON schema? What’s that?

From there he gets into a high level definition of what JSON schema is and the similarities it has to XML's structure. He then links to a PHP package that can help with the validation and how to use it (defining a simple JSON file, a schema and the code to perform the evaluation).

composer-patches – Simple patches plugin for Composer
Jan 31, 2017 @ 09:22:18

Leonid Mamchenkov has an interesting post to his site detailing a plugin for the popular Composer package management tool that makes it easier to apply patches to the current version of libraries in use: composer-patches

composer-patches is a plugin for Composer which helps with applying patches to the installed dependencies. It supports patches from URLs, local files, and from other dependencies.

This plugin makes it so that, during the normal Composer installation flow, you can apply your own patches to fix functionality that may not be corrected upstream yet. It replaces the need to "fork and fix" in your own version of the repository and cleans up the process to a more automated flow. It can also help when working with multiple people on the same code that's not your own and apply their patches to evaluate their changes.

You can find more information about the composer-packages plugin in the README on its GitHub repository.

Laravel News:
Checking the Code Complexity of your App
Jan 11, 2017 @ 11:52:58

On the Laravel News site there's an article posted showing you how to determine the complexity of your application using the phploc tool from Sebastian Bergmann.

Yesterday, Taylor made a post comparing the code complexity between Laravel and other frameworks. The tool he used to generate these reports is called phploc and it’s very easy to run on your own code base.

I decided as a means of comparison I would run that on the codebase for this site and just see what the results are.

The tutorial walks you through the installation of the tool (as a globally installed Composer package), how to execute it and what the results look like. These results include a lot of data including:

  • Average Class Length
  • Average Complexity per LLOC
  • (Use of) Global Constants
  • (Number of) Namespaces

phploc is useful for getting the overall numbers but he wanted something a bit more specific. For that he chose the PhpMetrics package that allows for deeper introspection into files and classes in your code to locate the complexity and find spots for refactoring.

Master Zend Framework:
How To Use Forked Repositories In Composer
Dec 21, 2016 @ 12:40:09

The Master Zend Framework site has continued their series covering Composer and some more advanced concepts than just the usual introduction. In this new tutorial Matthew Setter shows you how to work with forked repositories.

Have you ever submitted a patch to a repository which your application relies on, but, because that patch is vital to the uptime of your application, you can’t wait for it to be reviewed and merged into the next release?

In times like these, it’s fair to want them to move faster than they normally would, so that you don’t have to wait for the normal review, merge, and release cycles. [...] But, you may urgently need the patch to be applied and released. So, what do you do? In times like these, you can use Composer’s ability to use custom repositories, specifically a fork which you create and patch.

If this sounds appealing to you — because perhaps you’re in this very situation right now — let’s now step through the process of modifying your composer.json configuration so that you can use one.

He walks through the Composer configuration you'll need to update to work with the forked repository as you'd expect. He also covers changes that would need to be made for working with private repositories and using local files instead of remote.

Paul Jones:
Package Development Standards: "pds/skeleton" Now Open For Review!
Dec 16, 2016 @ 10:54:14

Paul Jones has a post to his site with a proposal for a standard structure for PHP packages to help provide consistency across the PHP package ecosystem. His proposal - the Package Development Standards initiative - defines the structure of the repository instead of conventions to be used in the package itself (like naming or object structure).

The new pds/skeleton (and the related research) for public review. If you are a package author, you are invited to post your comments and criticisms of the publication as issues on the relevant Github repository.

The pds/skeleton publication describes a set of standard top-level PHP package directories and files. If you are an author of more than three packages on Packagist, chances are you already follow the standard! That’s because PDS initiative researches the PHP package ecosystem to recognize commonly adopted development practices.

He's putting it out there for public review for now until he can get some feedback from the community on the structure and recommendations made. He also recommends going a head and adding "pds/skeleton" to your "require-dev" section to indicate your compliance to the suggestions he's presented.

Master Zend Framework:
How To Automate Projects Using Composer Scripts
Dec 06, 2016 @ 12:08:01

The Master Zend Framework site has posted a new tutorial showing you how to automate your projects with Composer, making use of the "scripts" section to add commands that can be automatically executed via a "composer" command line call.

Here, in the second part of the series, we’ll look at the scripts section of composer.json. If you’ve never heard of this section, it provides a way to automate tasks in your project.

Perhaps you think that this is unnecessary, as there is already such a wealth of tools available; including Make, Ant, Phing, and so on. But I see a place for having automation in Composer — though at first I didn’t.

Why? Because you can bring everything that much closer together. Because you can keep everything in a very tidy, organized, and well-structured way.

He starts with a brief overview of how the "scripts" section of the composer.json configuration works. He also shows examples of setting up scripts for code sniffing, running tests and generating test coverage reports. He also shows how to run these commands via the Composer command line and an the use of event handlers (like "post-install-cmd") to execute things at a certain point in the install/update process. He finishes off the post with an example from Zend Expressive calling an "Automation" to clear out the contents of the caches.

Symfony Finland:
Symfony Flex set to enable RAD (Rapid Application Development)
Dec 05, 2016 @ 11:58:37

On the Symfony Finland site there's a post that gets into the details of one of the new advancements in the Symfony ecosystem recently announced by Fabien Potencier at SymfonyCon Berlin 2016 - Symfony Flex.

The Symfony team has acknowledged this gap in their offering. And at SymfonyCon Berlin 2016 project lead Fabien Potencier announced what is known as Symfony Flex. Details are not precise, as I was not attending conference, but the tag line for Symfony Flex is: "Composition over Inheritance"

In essence it seems that Flex will allow for zero-config installation of Bundles. This is done using a Composer plugin. You will simply install packages with Composer and if the Bundle supports it, Composer will also author the necessary integration code and configuration.

As with any new thing, Flex support will start out pretty limited but as it grows in support the community should help it thrive in the Symfony ecosystem. The first release of the tooling for Flex will be available in early 2017.

Three Devs & A Maybe:
Episode 110 - Getting Started using Composer with Jonathan Klein
Nov 30, 2016 @ 13:35:02

The Three Devs and a Maybe have released an episode with guest Jonathan Klein talking about getting started using the Composer package manager.

In this weeks episode we are joined by Jonathan Klein to discuss his recently released Composer Pluralsight course. We start off by discussing the problem Composer is trying to solve, followed by past attempts at trying to solve it in the PHP landscape. Following this, we move on to discuss how the composer.json and composer.lock files work, the importance of versioning, the Semantic Versioning standard and how autoloading works. Finally, we delve into a couple of lesser-known Composer features, such as the event life-cycle, scripts and the plugin architecture that is present.

You can listen to this episode either through the in-page audio player or by downloading the mp3 directly. If you enjoy the show, be sure to subscribe to their feed to get more information on new episodes as they're released.

Master Zend Framework:
The Composer Command-Line Essentials
Nov 29, 2016 @ 10:15:52

The Master Zend Framework site has posted a tutorial that seeks to help you get the most out of Composer on the command line with some essential tips beyond just he basics.

I know that a series on Composer might seem odd. But, as Composer’s been a part of PHP for so long now, I feel that it’s something which most of us take for granted. It’s revolutionised the PHP landscape, making it easier than ever before to build great software in PHP. But do we really know how to get the most out of it. For that reason, I’ve created this series, so that you level up your skills and really get the most from it.

In part one of this series, I’m going to take you through Composer’s command-line. I’ve cherry-picked a key subset of the command-line options, and focused in on key switches, so that you can do more than you already can.

He skips over the basic "require", "install" and "update" handling covered in many other tutorials and instead covers:

  • project creation
  • the "show" command to list installed packages
  • "remove" to drop a package from the current dependencies
  • using "depends" to see package dependencies
  • finding outdates packages with (appropriately) the "outdated" command
  • seeing suggested packages with "suggest"

For each item on the list there's an example of the command, what kind of options is allows and, for some, the output generated as a result.

Jordi Boggiano:
PHP Versions Stats - 2016.2 Edition
Nov 18, 2016 @ 11:17:40

In his latest post Jordi Boggiano (of the Composer project) has released his PHP usage statistics for the second half of 2016 based on the information gathered during Composer installations.

It's stats o'clock! See 2014, 2015 and 2016.1 for previous similar posts.

A quick note on methodology, because all these stats are imperfect as they just sample some subset of the PHP user base. I look in the packagist.org logs of the last 28 days for Composer installs done by someone. Composer sends the PHP version it is running with in its User-Agent header, so I can use that to see which PHP versions people are using Composer with.

He compares them to the statistics from May 2016 showing some interesting but not unexpected changes, mostly in the growth of PHP 7+ versions. He shares a few of his own observations of the results and encourages library authors to start focusing on PHP 7 functionality rather than 5.5/5.6 compatibility. He also shares a secondary data set - the PHP versions that libraries require that, surprisingly, is moving a lot slower than the actual PHP version adoption.
