di52 version 2.0 is out!

The PHP 5.2 compatible dependency injection container finally out after some serious rework. Why version 2.0? While version 2.0 of DI52 is not a breaking change to 95% of version 1.0 code I’ve dropped the support for the convolute array-based instantiation interface in favour of the more intuitive instance method. I’ve written about it enough already I’ve written about DI52 new version in the…

Travis CI, PHP 5.2 and PHPUnit

Testing a PHP 5.2 compatible package on Travis with PHPUnit. Why bother? In a canned answer: due to WordPress minimum requirements. While PHP 5.2 has been deprecated for some time there is still software that will probably not run on it (a little portion of WordPress installations still runs on PHP 5.2). Second best answer for the thrill of it. Third answer: there are some edge cases that will…

After build methods support in di52

Small but useful addition to the PHP 5.2 compatible dependency injection container. Not all objects are built equal The DI52 package is born out of my need and will to use a dependency injection container in my WordPress projects. The [minimum supported version](!g wordpress minimum requirements) is still PHP 5.2 and DI containers for PHP 5.3 and above are abundant. Mocking an interface similar…

di52, the quest for performance 02

Performance lessons learnt along the road. The quest The quest is one to optimize DI52 performances without loss of functionality. I’ve outlined the main tool I will use to know where I stand in an earlier post as Tom Butler’s DI benchmarks. While I had to adapt them to my context the tool remains substantially the same. The starting point is this one: The DI52 places itself before in the middle…

di52, the quest for performance 01

What about the DI container performance? The inspiration Full disclosure: beside some common known good practices I’m a lame developer performance wise. In a WordPress echo system I know I should not make the same query twice, avoid any kind of data manipulation when necessary and so on. But deep down at the “let’s use this function in place of this one” level my knowledge is scarce to say the…

DI52 decorator pattern support 02

Decorator pattern support added to the di52 library. New methods With version 1.2.5 I’ve added decorator pattern support to the di52 package; two new methods are now available to support it. A closure based solution common to many dependency injection containers has always been available with a syntax like this (from the package README file): class A implements SomeInterface { public function…

DI52 decorator pattern support 01

Thinking about decorator support for the DI52 package. A PHP 5.2 compatible Dependency Injection container The DI52 library was born out of my frustration of not being able to find a PHP 5.2 compatible package I could use to leverage the dependency injection container pattern in WordPress plugins. The PHP 5.2 back-compatibility requirement sure limits the access to many libraries and I needed…

di52 automagical powers in the work

Adding auto-magical dependency resolution powers to the PHP 5.2 compatible DI container. New dog, old bone, new tricks While PHP 5.2 is deprecated it’s still listed among the minimum requirements for WordPress. But PHP has progressed very much and with it techniques and tools. Part as an experiment and part out of need I’ve developed di52: a PHP 5.2 compatible dependency injection container. The…
